Method and apparatus for power control in a radio communication system

摘要

Power control in a communication system (100) employing a Downlink Shared Control Channel (DSCH) and a Forward Access Control Channel (FACH) is described. The method includes, applying power control on the Downlink Shared Control Channel; deriving power control information from the power control on the Downlink Shared Control Channel; and applying to the Forward Access Control Channel the derived power control information from the power control on the Downlink Shared Control Channel in order to produce power control on the Forward Access Control Channel. The power control of the Forward Access Control Channel may be implemented by scheduling data in response to the derived power control information.

1. A method for power control in a communication system employing a Downlink Shared Control Channel (DSCH) and a Forward Access Control Channel (FACH), comprising:
applying power control on the Downlink Shared Control Channel; deriving power control information from the power control on the Downlink Shared Control Channel; and applying to the Forward Access Control Channel the derived power control information from the power control on the Downlink Shared Control Channel in order to produce power control on the Forward Access Control Channel in a case that loading on a DSCH in a neighboring cell exceeds a threshold value and loading on a FACH in the neighboring cell exceeds a threshold value, wherein applying power control information to the Forward Access Control Channel comprises grouping mobile stations with similar power requirements on a same Forward Access Control Channel.
