Channel allocation method for facilitating downlink power control and downlink adaptive beam forming

摘要

A method for transmitting information in a wireless TDMA communication system whereby such method allows downlink information to be transmitted during an entire slot assigned to a user of the communication system thus enabling the communication system to perform downlink adaptive beam forming and downlink power control. An allocation message that contains identification codes assigning users to a particular slot of uplink and downlink frames is first transmitted to the users during an entire slot of a first frame of a downlink block of frames. The corresponding slots of ensuing downlink frames are then used to transmit information to users during which downlink adaptive beam forming and/or downlink power control can be done. Corresponding slots of uplink frames are used by users to transmit information to the system equipment. Legacy users, which transmit and receive information in accordance with prior art methods, can simultaneously use the system with the users that transmit and receive information in accordance with the method of the present invention.
