Claim Text:
1. A method, in a radio network controller, for enhancing reception quality of transmissions on an uplink control channel from a user equipment to a serving base station, wherein the radio network controller, the user equipment, the serving base station, and a non-serving base station are comprised in a communication system, the method comprising: determining, when conditions for boosting the uplink control channel are fulfilled, a boosting factor based on a ratio of path gains of a channel from the user equipment to the serving base station and of a channel from the user equipment to the non-serving base station, respectively, wherein the ratio of path gains comprises a first path gain and a second path gain, the first path gain is a path gain of the channel from the user equipment to the non-serving base station and the second path gain is a path gain of the channel from the user equipment to the serving base station; and transmitting the determined boosting factor to the user equipment, whereby the reception quality of transmissions on the uplink control channel from the user equipment to the serving base station is enhanced by the user equipment boosting the uplink control channel based on the boosting factor.
