Claim Text:
1. A method by a Radio Network Controller (RNC) associated with one or more radio nodes controlling a set of cells that are candidates for use in Multi-Point High Speed Downlink Packet Access (MP-HSDPA) transmission to a user equipment, the method comprising: receiving indications of the fraction of uplink Enhanced Dedicated Channel (E-DCH) or uplink Radio Link Control (RLC) packets that are successfully received from the user equipment in respective ones of the set of cells, wherein the indications received for any given one of the respective cells is an indication that the fraction of uplink E-DCH or RLC packets successfully received from the user equipment at the radio node associated with the given cell exceeds a configured threshold; estimating relative uplink qualities of the respective cells, based on the indicated fractions; controlling which cells among the set of cells that are active for MP-HSDPA transmissions to the user equipment, based on the estimated relative uplink qualities; and sending signaling to the associated radio node to set the configured threshold in dependence on at least one of a downlink load of the given cell and a downlink transmit power of the given cell.
