Abstract

Directional-beam generative apparatus (62), and an associated method (102) for a radio communication station (36) forms directional antenna beam patterns (22, 34, 36, 52, 54, 56) for the communication of communication signals with remote communication stations (24, 26, 28) operable in a TDMA communication system (10). Channels (12, f1) are allocated for effectuation of communications between the radio communication station (18) and the remote stations (24, 26, 28) responsive to indications of locations at which the remote communication stations (24, 26, 28) are indicated to be positioned. Remote communication stations indicated to be positioned within a selected area are allocated to channels (12, f1) formed upon a single carrier (f1).
