Abstract:
1. A method of selecting an enhanced transport format combination used for maximizing power utilization of and power limitation avoidance in a communication network system comprising a communication network entity communicating with a plurality of user equipments on uplink and downlink channels over a radio interface, comprising: determining a power consumption for an acknowledgement negative acknowledgement transmission and a channel quality indicator transmission on an uplink channel during an enhanced dedicated channel transmission; using said determined power consumption for predicting available power for each transmission slot of said enhanced dedicated channel transmission; determining available signal to interference-plus-noise ratio of each transmission slot based on said predicted available power for each transmission slot; converting said determined available signal to interference-plus-noise ratio of each transmission slot to symbol information of each transmission slot; determining a received block information for whole transmission time interval of said enhanced dedicated channel transmission based on said symbol information of each slot; converting said determined receive block information to an available effective signal to interference-plus-noise ratio for said whole transmission time interval of said enhanced dedicated channel transmission; determining an available effective power offset value based on said available effective signal to interference-plus-noise ratio; and selecting said enhanced transport format combination based on said determined available effective power offset value.
