Patent ID: 7650154

Claim:
A method, comprising: adaptively setting a reservation of channelization codes or an allowed power for a downlink shared channel of a transceiver based on parameters for a minimum allowed spreading factor or an allowed power level; setting the parameters depending on a traffic load, a total load of a cell and an availability of channelization codes; measuring an average transmitted power of a physical downlink shared channel; measuring a relative activity factor of the physical downlink shared channel, the relative activity factor defining the ratio between silence and activity of the physical downlink shared channel during an observation period; measuring a weighted code blocking rate, the weighted code blocking rate comprising a relative time during an observation period in which a larger bit rate than an actually allocated bit rate could have been allocated to a user equipment according to a link adaptation criteria for controlling the downlink shared channel; adaptively adjusting at least one of a root spreading factor and the allowed power for the downlink shared channel of the transceiver based on results of the measuring; and decreasing the allowed power when A is smaller than TH A1 and P txDSCHest is smaller than (P txDSCHallowed −X); wherein A comprises an activity factor of a downlink channel, TH A1 comprises a threshold parameter, P txDSCHest comprises an estimated power of the downlink shared channel, P txPDSCHallowed comprises an allowed power for the physical downlink shared channel, and X comprises a preset power value.
