Abstract

A method of controlling uplink power level in a terminal (1) of a communication system, wherein the terminal transmits on a first uplink channel type (8) to a first base station (2) and transmits in soft handover on a second uplink channel type (9) to the first base station and to a second or subsequent base station (3, 4) comprises receiving power control commands at the terminal on a downlink dedicated channel (5, 6, 7) from each base station. The uplink power level for the first and second uplink channel type (8, 9) is adapted, wherein the downlink dedicated channel (7) from the first base station provides power control commands for the first uplink channel type; and wherein the downlink dedicated channel (5, 6) from the second and subsequent base station (3, 4) provides power control commands for the second uplink channel type.
