POWER CONTROL FOR REVERSE LINK CHANNELS

摘要

An arrangement for minimizing the number of power control bits required by a mobile unit (10) to simultaneously power control soft-handoff (DPCCH/DPDCH (12')) and non-soft handoff reverse link (HS=DPCCH) for supporting packet transfer over high speed downlink shared channel (HS-DSCH). A conventional DPCCH reverse link (12) and a high speed HS-DPCCH link (13) couple the mobile unit to the serving base station. The mobile unit also receives power control information for other reverse links coupling the mobile unit (10) to target base stations (2-N). Mobile unit (10) infers the power control information for the conventional link (DPCCH/DPDCH) from the serving base station from HS-DPCCH power control information. As a consequence, only one power control command or bit is sent by the serving base station.
