Patent ID: 7010318

Claim:
A method for controlling uplink transmission power in a handover region by a UE (User Equipment) in communication with a Node B using an FCS (Fast Cell Selection) scheme, comprising the steps of: storing TPC (Transmission Power Control) commands received for a specific duration from a plurality of cells in an active set, if the UE enters the handover region during communication with a current best cell; selecting a cell among the plurality of cells in the active set as a next best cell using the stored TPC commands; comparing the TPC commands from a current best cell with the TPC commands from the next best cell for the specific duration, which is defined by a number of time slots counted backward from a point in time at which handover is executed from the current best cell to the next best cell; determining a transmission power offset based on a difference between numbers of the TPC commands having different values; and transmitting initial transmission power for the next best cell at a transmission power level determined considering the transmission power offset.
