Power control in a communication system employing first and second channels, by: applying power control on the first channel, deriving power control information therefrom, and applying same to the second channel in order to produce power control on the second channel. DSCH power control is the first channel used to determine power consumption on FACH that is the second channel. The power control information may be obtained: directly from RNC power control entity (if RNC based power control), or indirectly from Node B power control entity (if TPC power control at the Node B).; The power control on the second channel may be obtained: via TFCS selection, scheduling of FACHs (number of codes / data rate) using a power management calculation based on the above, power cost calculation using C/I difference method, use of fixed or dynamically updated C/I values, or queueing and serving of UEs with similar power requirements on the FACH at the same time. This provides the following advantage(s): - maximisation of throughput on FACH(s) - exploitation of DSCH power control removes the need for additional measurements to be taken by the UE. |
