Abstract

To increase throughput efficiency and attain a higher achieved bit rate for data transmissions over a high speed shared channel, a variable transmit power increase factor is used to control the maximum rate at which the power at which data is transmitted over the high speed shared channel can increase. In one non-limiting implementation, the power increase factor F is varied with the current total downlink transmitted power available for high speed downlink transmission. For example, when the available high speed shared channel power is large, the variable transmit power increase factor assumes a more conservative value, e.g., a smaller F value, at the beginning of the high speed downlink transmission, and then a more liberal value, e.g., a larger F value, later during the high speed downlink transmission.
