Variable rate forward power control for multichannel applications

摘要

Separate power control for the forward voice channel and forward data channel is provided without using additional bandwidth or decreasing the amount of pilot signal provided from the mobile to the base station. Alternating voice and data power control commands or information are transmitted in the pilot channel by a mobile to a base station. In one embodiment, the power control portion of a first pilot channel segment is used to provide power control for the forward voice channel and then in the following pilot channel segment, the power control portion is used to provide power control for the forward data channel. In other embodiments, other than a 50/50 mix between voice and data power control is provided in the mobile's pilot channel. For example, forward voice channel power control commands may be transmitted two or more times for each transmission of forward data channel power control commands. <IMAGE>
