Abstract
Systems and methodologies are described that facilitate employing a paging indicator channel in connection with high speed channels in a wireless communications network. A paging indicator transmission can be sent on the paging channel to one or more mobile devices. The paging indicator indicates that additional information such as a full paging messages, other control plane data or other user plane data is expected to be transmitted at a specific time instant (e.g., subframe) on the associated high speed channel. A set of parameters can be transmitted on common channels that specify a set of associated subframes in a high speed channel. Mobile devices can analyze the set of parameters to determine the associated subframes and receive the subframes in accordance with a schedule.

This application also claims the benefit of U.S. Provisional Patent application Ser. No. 60/895,399, entitled “PICH-HS TIMING AND OPERATION” which was filed on Mar. 16, 2007. The entireties of the aforementioned applications are herein incorporated by reference.
  • BACKGROUND
  • [0002]
    I. Field
  • [0003]
    The following description relates generally to wireless communications, and more particularly to relative timing and operation between paging indicator channel and high speed channels.
  • [0004]
    II. Background
  • [0005]
    Wireless communication systems are widely deployed to provide various types of communication content such as, for example, voice, data, and so on. Typical wireless communication systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, . . . ). Examples of such multiple-access systems may include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, and the like. Additionally, the systems can conform to specifications such as third generation partnership project (3GPP), 3GPP long term evolution (LTE), etc.
  • [0006]
    Generally, wireless multiple-access communication systems may simultaneously support communication for multiple mobile devices. Each mobile device may communicate with one or more base stations via transmissions on forward and reverse links. The forward link (or downlink) refers to the communication link from base stations to mobile devices, and the reverse link (or uplink) refers to the communication link from mobile devices to base stations. Further, communications between mobile devices and base stations may be established via single-input single-output (SISO) systems, multiple-input single-output (MISO) systems, multiple-input multiple-output (MIMO) systems, and so forth. In addition, mobile devices can communicate with other mobile devices (and/or base stations with other base stations) in peer-to-peer wireless network configurations.
  • [0007]
    MIMO systems commonly employ multiple (NT) transmit antennas and multiple (NR) receive antennas for data transmission. A MIMO channel formed by the NT transmit and NR receive antennas may be decomposed into NS independent channels, which may be referred to as spatial channels, where NS≦{NT, NR}. Each of the NS independent channels corresponds to a dimension. Moreover, MIMO systems may provide improved performance (e.g., increased spectral efficiency, higher throughput and/or greater reliability) if the additional dimensionalities created by the multiple transmit and received antennas are utilized.
  • [0008]
    MIMO systems may support various duplexing techniques to divide forward and reverse link communications over a common physical medium. For instance, frequency division duplex (FDD) systems may utilize disparate frequency regions for forward and reverse link communications. Further, in time division duplex (TDD) systems, forward and reverse link communications may employ a common frequency region. However, conventional techniques may provide limited or no feedback related to channel information.

    Referring now to FIG. 1, a wireless communication system 100 is illustrated in accordance with various embodiments presented herein. System 100 comprises a base station 102 that can include multiple antenna groups. For example, one antenna group can include antennas 104 and 106, another group can comprise antennas 108 and 110, and an additional group can include antennas 112 and 114. Two antennas are illustrated for each antenna group; however, more or fewer antennas can be utilized for each group. Base station 102 can additionally include a transmitter chain and a receiver chain, each of which can in turn comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators multiplexers, demodulators, demultiplexers, antennas, etc.), as will be appreciated by one skilled in the art.
  • [0043]
    Base station 102 can communicate with one or more mobile devices such as mobile device 116 and mobile device 122; however, it is to be appreciated that base station 102 can communicate with substantially any number of mobile devices similar to mobile devices 116 and 122. Mobile devices 116 and 122 can be, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable device for communicating over wireless communication system 100. As depicted, mobile device 116 is in communication with antennas 112 and 114, where antennas 112 and 114 transmit information to mobile device 116 over a forward link 118 and receive information from mobile device 116 over a reverse link 120.

Also, while base station 102 utilizes beamforming to transmit to mobile devices 116 and 122 scattered randomly through an associated coverage, mobile devices in neighboring cells can be subject to less interference as compared to a base station transmitting through a single antenna to all its mobile devices. Moreover, mobile devices 116 and 122 can communicate directly with one another using a peer-to-peer or ad hoc technology as depicted.
  • [0045]
    Turning to FIG. 2, illustrated is a communications apparatus 200 for employment within a wireless communications environment. The communications apparatus 200 can be a base station or a portion thereof, a mobile device or a portion thereof, or substantially any communications apparatus that receives data transmitted in a wireless communications environment. A paging indicator channel (PICH) can be employed to notify a mobile device that it is possibly being paged. The mobile device reads another channel to verify the page. Conventionally, the mobile device read the secondary common control physical channel (S-CCPCH). However, the communications apparatus can employ the PICH with high speed channels in addition to the S-CCPCH channel. For example, the high speed channels can include a high speed physical downlink shared channel (HS-PDSCH) and/or a high speed shared control channel (HS-SCCH). The communications apparatus can employ components described below to facilitate timing and operation of the PICH channel with high speed channels. The communications apparatus 200 can include a pager 202 that can transmit a paging indicator to one or more mobile devices and an HS scheduler 204 that can schedule and transmit data associated with the PICH channel for the mobile device corresponding to the paging indicator.
  • [0046]
    According to an example, the communications apparatus 200 can employ the PICH channel in connection with the S-CCPH or high speed channels to facilitate paging a mobile device and/or a plurality of mobile devices. This can occur, for example, when the communications apparatus 200 detects data (e.g., incoming call, downloadable data, etc.) that is to be transmitted to the mobile device. The pager 202 sends a paging indicator to a mobile device on the PICH channel. It is to be appreciated that the pager 202 can send a plurality of paging indicators to a plurality of mobile devices. In one embodiment, the paging indicator is set in a PICH frame by the pager 202. The paging indicator notifies a mobile device that data is located on at least one other channel. The mobile device reads the other channels to verify that the paging indicator actually designates a page to the mobile device (e.g., that the data on the other channel is the mobile device's data). The pager 202 can interoperate with both the S-CCPCH channels and high speed channels such as a high speed shared control channel (e.g., HS-SCCH) and/or a high speed shared data channel (e.g. HS-DSCH, HS-PDSCH, etc.). When a paging indicator is received by user equipment or mobile device, the paging indicator informs the mobile device that it should expect to receive more information such as a full paging message, other control plane data or user plans data at a specific time instance (e.g., subframe) on associated high speed channels. The association between paging indicator and high speed channels can be determined by a set of parameters established as a standard or signaled in overhead signaling messages on common channels. The communications apparatus 200 can provide the set of parameters that define scope, length and timing of data on the high speed channels. In one embodiment, the base station 200 can announce the set of parameters on common channels. According to another aspect, the base station 200 can announce a subset on common channels and the remaining parameters in the set can be announced per transmission on dedicated messages (e.g., signaled on dedicated channels). Pursuant to an illustration, the set of parameters can be transmitted on, for example, a broadcast channel along with other system information. It is to be appreciated that other common channels can be employed. For example, the set of parameters or a subset thereof can be transmitted on the high speed shared control channel (e.g., HS-SCCH channel). These parameters can be employed by the HS scheduler 204 to schedule data associated with the paging indicator on the high speed channel.
  • [0047]
    The HS scheduler 204 can schedule data for a mobile device associated with the paging indicator on the high speed channel based at least in part on the set of parameters provided by the pager 202. The parameters indicate a set of high speed shared control channel subframes or high speed shared data channel subframes that are associated with paging indicator on the PICH channel. For example, the set of parameters can indicate a number of subframes that a mobile device should attempt to receive, a number of retransmissions possible in a HARQ scenario, a degree of multiplexing or interleaving between subframes destined for different mobile devices and/or a number of subframes a mobile device should monitor following successful receipt. The paging indicator set in the PICH by pager 202 can indicate that a paging message, upper layer signaling specific to a mobile device or mobile device specific data is to be scheduled for the mobile device. The HS scheduler 204 can schedule the paging message, upper layer signaling or device specific data in one of the associated subframes on the high speed channel. The HS scheduler 204 determines an appropriate time to schedule based upon an offset determined for the lifetime of the channels.
  • [0048]
    Now referring to FIG. 3, illustrated is a wireless communications system 300 that can generate a paging indicator that can be utilized to receive data on a high speed channel such a high speed shared control channel and/or a high speed shared data channel. The system 300 includes a base station 302 that communicates with a mobile device 304 (and/or any number of disparate mobile devices (not shown)). Base station 302 can transmit information to mobile device 304 over a forward link channel; further base station 302 can receive information from mobile device 304 over a reverse link channel. Moreover, system 300 can be a MIMO system. Additionally, the system 300 can operate in an OFDMA wireless network, a 3GPP LTE wireless network, etc. Also, the components and functionalities shown and described below in the base station 302 can be present in the mobile device 304 as well and vice versa, in one example; the configuration depicted excludes these components for ease of explanation.
  • [0049]
    Base station 302 includes a pager 306 that can transmit a paging indicator 318 to one or more mobile devices, an HS scheduler 308 that can schedule and transmit data for the mobile device and associated with the paging indicator 318. Additionally, the base station 302 can include a parameter selector 310 that can determine a set of parameters 322 sent to mobile device 304 on a common channel 320 (e.g., HS-SCCH, a broadcast channel, etc.). The set of parameters 322 can establish a configuration for mobile device 304 to utilize when receiving data on a high speed channel 324 in response to a paging indicator 318. The parameter selector 310 can ascertain parameters 322 based upon scope and content of data to be transmitted to the mobile device 304 as well as configurations of system 300. For example, the parameter selector 310 can choose parameters 322 for the high speed transmission associated with the paging indicator 318 such that the parameters 322 conform to the configuration of the system 300 (e.g., HARQ configurations, HS-SCCH operation, HS-SCCH less operation, etc.).
  • [0050]
    Mobile device 304 includes a parameter analyzer 312 that analyzes the set of parameters 322 to determine how data will be transmitted on a HS channel 324 in association with a paging indicator 318 and a HS decoder 314 that retrieves data on the high speed channel 324 (e.g., HS-SCCH, HS-PDSCH, HS-DSCH, etc.) in accordance with the analyzed parameters. In one example, the mobile device 304 can receive a paging indicator 318 from the base station 302 on a paging indicator channel 316 that indicates a possibility that the mobile device 304 is being paged The mobile device 304 can read another channel to ascertain if it is being paged and, if so, retrieve data on the other channel. Pursuant to an example, the other channel can be the high speed channel 324 and the data retrieved can be high speed data 326.
  • [0051]
    According to an example, the base station 302 can obtain data for the mobile device 304. The data can be from another mobile device (e.g., a voice communication, a data transfer, etc.), a wired device on a network communicatively coupled to the base station 302, a server and the like. It is to be appreciated that the base station 302 can possess data to be transmitted to the mobile device 304 (e.g. power control data, assignment data, etc.). The pager 306 of base station 302 can transmit a paging indicator 318 to the mobile device 304 on the paging indicator channel (PICH) 316 to notify the mobile device 304 that data is waiting. The timing of the paging indicator 318 can be based at least in part on the discontinuous reception (DRX)/wake up cycle of mobile device 304. For instance, the pager 306 can set the paging indicator 318 when the mobile device 304 wakes up to listen for pages every DRX period. The pager 306 sets the paging indicator 318 in a PICH frame to notify the mobile device 304 that high speed data 326 is scheduled in associated subframes of the high speed channel 324 (e.g., HS-SCCH channel or the HS-PDSCH channel). In one aspect, the high speed data 326 can include a paging message, upper layer signaling specific to mobile device 304 or data specific to mobile device 304. Pursuant to an illustrative embodiment, the paging indicator 318 set on the PICH channel 316 points to a set of associated subframes on the HS channels 324. Following the paging indicator 318, the HS scheduler 308 of the base station 302 schedules the high speed data 326 on the high speed channels 324 in accordance with the set of parameters 322 established by the parameter selector 310 (e.g., schedules the information on the set of associated subframes). A timing offset between the time the PICH frame with the paging indicator 318 ends and the beginning of a first subframe in the set of associated subframes is established for the lifetime of the channels. The timing offset can be transmitted by the base station 302 on the common channel 320. The mobile device 304 can employ the timing offset to properly synchronize receipt of the paging indicator 318 and the associated transmitted information 326 on the high speed channels 324.
  • [0052]
    The base station 302 provides parameter selector 310 that determines a set of parameters 322 that can be transmitted as overhead signaling on a common channel 320. The set of parameters 322 relates to how data 326 associated with a paging indicator 318 is transmitted on a high speed channel 324. The parameter selector 310 ascertains a first set of high speed subframes (e.g., HS-SCCH/HS-PDSCH subframes) pointed to by the paging indicator 318. This parameter, which can be denoted NUM_HS_SUBFRAMES_SET1, indicates the number of subframes that mobile device 304 should attempt to receive. According to an aspect, this value can be n frames where n is an integer value between 5 and 20, inclusive. In addition, the parameter selector 310 can determine a second set of subframes that the mobile device 304 should attempt to receive. The parameter, NUM_HS_SUBFRAMES_SET2, indicates the number of subframes the mobile device 302 extends it monitoring following successful receipt of the first set. In addition, the parameter selector 310 can determine parameters associated with hybrid automatic repeat requests (HARQ) configurations. For example, the parameter selector 310 can establish BLIND_HARQ_NUM_RETRANS that indicates a number of transmission repeats for the forward link only. Moreover, the parameter selector 310 can establish BLIND_HARQ_STRIDE that indicates spacing in terms of subframes for the aforementioned retransmissions. Pursuant to an illustration, forward link transmission can be repeated BLIND_HARQ_NUM_RETRANS times every (BLIND_HARQ_STRIDE+1) subframe(s). According to an aspect, BLIND_HARQ_NUM_RETRANS can be an integer between 0 and 7 inclusive and BLIND_HARQ_STRIDE can be established between 0 and 5 inclusive. The parameter selector 310 can determine a floor and ceiling for the number of HARQ instances based upon the chosen parameters. For example, a ceiling can be given by (NUM_HS_SUBFRAMES_SET1/(BLIND_HARQ_NUM_RETRANS+1)) or a floor can be provided by the same formulation. Moreover, the parameter selector 310 instructs the HS scheduler 308 how to schedule HARQs. Pursuant to an illustration, each (BLIND_HARQ_STRIDE+1) HARQs are interleaved. Transmissions are back to back when the stride parameter is zero. When the stride parameter is set to one, two HARQs are interleaved and so on.
  • [0053]
    In accordance with another aspect, the parameter selector 310 can determine parameters based upon configurations of the network or other entity. For example, regular HS-SCCH and HS-SCCH less operations can be employed. However, the parameter selector 310 can indicate that bit exact HS-SCCH repetition is to be utilized to enable the mobile device 304 to employ Chase combining. In addition, incremental redundancy HARQ can be predefined and the parameter selector 310 can utilize the predefinition. Moreover, the parameter selector 310 can optimize parameter coding in the common channel 320 to avoid combinations of parameters that cannot be achieved. In addition, it is to be appreciated that the set of parameters 322 can be conveyed to mobile device 304 during connection negotiation.
  • [0054]
    The mobile device 304, upon receiving the paging indicator 318, can retrieve a high speed data transmission 326 from the base station 302 scheduled on another channel such as the S-CCPCH channel, the HS-SCCH channel, the HS-PDSCH channel or other high speed channel. The parameter analyzer 312 analyzes a set of parameters 322 on a common channel 320 to determine the parameters established by the parameter selector 310 of the base station 302. The parameters 322 instruct the mobile device 304 the subframes to receive and/or how the subframes are organized. The timing offset established for the lifetime of the channels indicates when the set of associated subframes determined by the parameter analyzer 312 are scheduled on the HS channels 324. The HS decoder 314 of the mobile device 304 subsequently receives and decodes the subframes in accordance with the parameters. For example, the HS decoder 314 receives and decodes the number of subframes on the HS channels 324 indicated by the corresponding parameter. Following successful receipt of the first set of subframes, the HS decoder 314 monitors and attempts to receive a second set of subframes.
  • [0055]
    According to another aspect, system 300 supports both HS-SCCE and HS-SCCH less operations. These operations are configured by the network. In HS-SCCH less operation, the mobile device 304 is configured with a set of transport formats. In addition, the mobile device 304 is configured with one or more walsh channels that can be blindly decoded. Moreover, pursuant to an illustrative embodiment, two high speed downlink shared channels (HS-DSCH) Radio Network Transaction Identifiers (H-RNTI) are monitored by the mobile device 304 at all times. In one aspect, the two H-RNTIs can be a common and dedicated H-RNTI.
  • [0056]
    Now referring to FIG. 4, an example timing diagram 400 that illustrates PICH to HS timing. The timing diagram 400 depicts relative timing between a variety of channels in communications system. For example, the timing diagram 400 includes primary and secondary synchronization channels (SCH), any common pilot channel (CPICH), a primary common control channel (P-CCPCH), a secondary common control channel (S-CCPCH), a paging indicator channel (PICH), acquisition indicator channel (AICH) access slots, a dedicated physical channel (DPCH), a fractional dedicate physical channel (F-DPCH) and HS-SCCH subframes. The PICH can be employed with both S-CCPCH and HS-SCCH. As shown in the timing diagram 400, S-CCPCH and HS-SCCH operate on different timings. Accordingly, offsets need to be determined to account for timing differences.
  • [0057]
    As the PICH can serve both S-CCPCH and HS-SCCH, the conventional timing needs adjustment. Conventionally, the PICH served the S-CCPCH and provided a timing τPICH that indicated the offset between the PICH frame and an associated S-CCPCH frame. In an embodiment, τPICH is 7680 chips in duration. However, this duration after a PICH frame can align with a middle portion of a HS-SCCH subframe. Accordingly, an additional offset τHS-SCCH needs to be established. Pursuant to an illustration, τHS-SCCH is determined by the respective frame offset of the PICH frame and HS-SCCH subframe as illustrated in the timing diagram 400.
  • [0058]
    Turning now to FIG. 5, illustrated is an exemplary timing diagram 500 that further depicts the timing between PICH and HS-SCCH. The timing diagram 500 includes a PICH frame 502 that includes a paging indicator pointing to a set of associated HS-SCCH subframes 504 and an offset 506 that specifies the timing offset therebetween. According to an example, the first HS-SCCH subframe in the set of associated subframes 504 starts τPICHHS-SCCH chips after the transmitted PICH frame 502 that includes the paging indicator. Pursuant to an illustration, τPICH is 7680 chips. Thus, τHS-SCCH can be determined as the offset between a time computed as the end of the PICH frame plus 7680 chips. In accordance with an aspect, τHS-SCCH is less than 7680 chips (e.g., less than the duration of τPICH). According to another aspect, τHS-SCCH can be zero. Thus, τPICH is the only timing required and can be relative only to HS-SCCH/HS-DSCH. In addition, it is to be appreciated that multiple PICH channels can exist that point to multiple or a plurality of HS channels (e.g., HS-SCCH and/or HS-DSCH).
  • [0059]
    Referring now to FIGS. 6-9, exemplary diagrams are depicted in accordance with an aspect of the subject disclosure. For the purposes of simplicity of explanation, the examples illustrate timing diagrams that include a PICH channel, a HS-SCCH channel and a HS-PDSCH channel. Each block in a row of a channel indicates a frame and/or subframe. It is to be appreciated that FIGS. 6-9 are for illustrative purposes and the disclosed subject matter is not limited to the scope of these examples. Those skilled in the art should appreciate how the timing diagrams can be extended to other channel pairings, parameter combinations etc.

    In FIG. 6, an example 600 is illustrated that depicts PICH to HS operation with two user equipment (UE) devices, UE1 and UE2. In example 600, the parameter NUM_HS_SCCH_SET1 is 5, BLIND_HARQ_NUM_RETRANS is 4, BLIND HARQ STRIDE is 0 and BLIND_HS_SCCH_SET2 is 0. As shown in example 600, UE1 wakes up 3 HS-SCCH subframes after the end of the PICH radio frame that includes the paging indicator to UE1. UE1 attempts to decode any transmission on the associated HS-SCCH or HS-SCCH less channels (e.g., HS-PDSCH) for 5 subframes. The transmission is repeated for 5 subframes. Subsequently, UE1 can employ discontinuous reception (DRX). Similarly, UE2 wakes up 3 subframes after the end of the PICH radio frame that includes the paging indicator to UE2. UE2 is configured to utilize HS-SCCH less operation and attempts to decode any transmission on the HS-PDSCH channel for the next 5 subframes.
  • [0061]
    In FIG. 7, an example 700 is illustrated that depicts PICH to HS operation. In example 700, the parameter NUM_HS_SCCH_SET1 is 5, BLIND_HARQ_NUM_RETRANS is 4, BLIND_HARQ_STRIDE is 0 and BLIND_HS_SCCH_SET2 is 10. Thus, in example 700, the UE monitors and attempts to receive 10 subframes after successful receipt of the first set under the same conditions as the first set. The UE wakes up 3 HS-SCCH subframes after the end of the PICH radio frame that includes the paging indicator. The UE attempt to decode any transmission on the associated HS-SCCH or HS-SCCH less channels wherein the transmission is repeated over 5 consecutive subframes. If the UE successfully decodes the HS-SCCH or HS-PDSCH transmission destined for the UE, it attempts to receive packets over the next 10 subframes.

    In FIG. 8, an example 800 is illustrated in accordance with an aspect of the subject disclosure. Example 800 is similar to example 700 illustrated in FIG. 7. However, in example 800, the PICH is aligned with an S-CCPCH channel. The S-CCPCH channel is not aligned to the P-CCPCH radio frames.
  • [0063]
    In FIG. 9, an example 900 is illustrated according to another aspect of the subject disclosure. In example 900, PICH to high speed operation is depicted with two UEs, UE1 and UE2. In example 900, the parameter NUM_HS_SCCH_SET1 is 12, BLIND_HARQ_NUM_RETRANS is 2, BLIND_HARQ_STRIDE is 1 and BLIND_HS_SCCH_SET2 is 0. As shown in this example, UE1 and UE2 wake up 3 subframes after the end of the PICH radio frame that include the paging indicators to UE1 and UE2. UE1 and UE2 attempt to decode any transmission on the HS-SCCH channel or the HS-PDSCH channel (e.g., the HS-SCCH less channel) for the next 12 subframes. The transmission is repeated over 3 subframes that are one frame apart. As depicted in example 900, the subframes destined for UE1 are interleaved with subframes intended for UE2. After receiving 12 subframes, UE1 and UE2 can utilize DRX.

    Turning to FIG. 10, illustrated is a methodology 1000 that facilitates employing a page channel to notify mobile devices of data on high speed channels. At reference numeral 1002, parameters are determined that are transmitted on a common channel to mobile devices to indicate how high speed data on high speed channels should be received.

For example, the parameters can determine the number of repeats of a transmission and the degree of interleaving between one or more transmissions destined for distinct mobile devices. At reference, numeral 1006, a paging indicator is transmitted to at least one mobile device. Pursuant to an illustration, the paging indicator is associated with a set subframes scheduled on the high speed channel according to the determined parameters. At reference numeral 1008, the high speed data is sent to at least one mobile device. The high speed data is sent as scheduled in the set of associated subframes.

At 1102, a paging indicator is received on a paging changing such as the PICH channel. The paging indicator on the PICH can indicate that a paging message, upper layer signaling specific to a mobile device or mobile device specific data is scheduled on an associated high speed channel. At reference numeral 1104, data on a common channel is analyzed to determine parameters contained therein. The parameters can define how high speed data associated with the paging indicator is scheduled on the high speed channel. The parameters instruct a mobile device as to how many subframes to attempt to receive, the configuration of the subframes, and whether or not to monitor following successful receipt. At reference numeral 1106, high speed data is obtained in accordance with the determined parameters. At reference numeral 1108, additional high speed transmissions are monitored following successful receipt of the obtained high speed data associated with the paging indicator.

    It will be appreciated that, in accordance with one or more aspects described herein, inferences can be made regarding selecting and/or determining parameters employed in a paging indicator to specify data in associated high speed channels in a wireless communications network. As used herein, the term to “infer” or “inference” refers generally to the process of reasoning about or inferring states of the system, environment, and/or user from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic—that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources.

  • [0076]
    At base station 1410, traffic data for a number of data streams is provided from a data source 1412 to a transmit (TX) data processor 1414. According to an example, each data stream can be transmitted over a respective antenna. TX data processor 1414 formats, codes, and interleaves the traffic data stream based on a particular coding scheme selected for that data stream to provide coded data.
  • [0077]
    The coded data for each data stream can be multiplexed with pilot data using orthogonal frequency division multiplexing (OFDM) techniques. Additionally or alternatively, the pilot symbols can be frequency division multiplexed (FDM), time division multiplexed (TDM), or code division multiplexed (CDM). The pilot data is typically a known data pattern that is processed in a known manner and can be used at mobile device 1450 to estimate channel response. The multiplexed pilot and coded data for each data stream can be modulated (e.g., symbol mapped) based on a particular modulation scheme (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM), etc.) selected for that data stream to provide modulation symbols. The data rate, coding, and modulation for each data stream can be determined by instructions performed or provided by processor 1430.
  • [0078]
    The modulation symbols for the data streams can be provided to a TX MIMO processor 1420, which can further process the modulation symbols (e.g. for OFDM). TX MIMO processor 1420 then provides NT modulation symbol streams to NT transmitters (TMTR) 1422 a through 1422 t. In various embodiments, TX MIMO processor 1420 applies beamforming weights to the symbols of the data streams and to the antenna from which the symbol is being transmitted.
  • [0079]
    Each transmitter 1422 receives and processes a respective symbol stream to provide one or more analog signals, and further conditions (e.g., amplifies, filters, and upconverts) the analog signals to provide a modulated signal suitable for transmission over the MIMO channel. Further, NT modulated signals from transmitters 1422 a through 1422 t are transmitted from NT antennas 1424 a through 1424 t, respectively.
  • [0080]
    At mobile device 1450, the transmitted modulated signals are received by NR antennas 1452 a through 1452 r and the received signal from each antenna 1452 is provided to a respective receiver (RCVR) 1454 a through 1454 r. Each receiver 1454 conditions (e.g., filters, amplifies, and downconverts) a respective signal, digitizes the conditioned signal to provide samples, and further processes the samples to provide a corresponding “received” symbol stream.
  • [0081]
    An RX data processor 1460 can receive and process the NR received symbol streams from NR receivers 1454 based on a particular receiver processing technique to provide NT “detected” symbol streams. RX data processor 1460 can demodulate, deinterleave, and decode, each detected symbol stream to recover the traffic data for the data stream. The processing by RX data processor 1460 is complementary to that performed by TX MIMO processor 1420 and TX data processor 1414 at base station 1410.
  • [0082]
    A processor 1470 can periodically determine which precoding matrix to utilize as discussed above. Further, processor 1470 can formulate a reverse link message comprising a matrix index portion and a rank value portion.
  • [0083]
    The reverse link message can comprise various types of information regarding the communication link and/or the received data stream. The reverse link message can be processed by a TX data processor 1438, which also receives traffic data for a number of data streams from a data source 1436, modulated by a modulator 1480, conditioned by transmitters 1454 a through 1454 r, and transmitted back to base station 1410.
  • [0084]
    At base station 1410, the modulated signals from mobile device 1450 are received by antennas 1424, conditioned by receivers 1422, demodulated by a demodulator 1440, and processed by a RX data processor 1442 to extract the reverse link message transmitted by mobile device 1450. Further, processor 1430 can process the extracted message to determine which precoding matrix to use for determining the beamforming weights.
  • [0085]
    Processors 1430 and 1470 can direct (e.g., control, coordinate, manage, etc.) operation at base station 1410 and mobile device 1450, respectively. Respective processors 1430 and 1470 can be associated with memory 1432 and 1472 that store program codes and data. Processors 1430 and 1470 can also perform computations to derive frequency and impulse response estimates for the uplink and downlink, respectively.
