Abstract
A packet switched communications system is provided in which a station communicates with at least one user over downlink communication channel, the downlink communication channel being divided into a plurality of frames and each frame including a plurality of data packets. Each data packet is directed to a predetermined user and includes transmission power control information for said user. An extended transmission power control information field is provided in at least one data packet in every frame, which includes transmission power control information for 10 at least one other user of the communication system.
Claims5
