METHOD AND APPARATUS FOR CONTROLLING UPLINK TRANSMISSION POWER BASED ON ACCUMULATED TRANSMIT POWER CONTROL COMMANDS AND CORRESPONDING UPLINK SUBFRAME SETS

摘要

A method and apparatus for controlling uplink (UL) transmit power is described. A wireless transmit / receive unit (WTRU) may receive a configuration of UL subframe sets and maintain a plurality of transmit power control (TPC) command accumulator values corresponding to respective UL subframe sets of the UL subframe sets. have. The WTRU receives a TPC command in subframe n of the downlink (DL) transmission, the received TPC command determines subframe n + k of the corresponding UL transmission, and determines which of the UL subframe sets Determine if subframe n + k belongs and adjust the TPC command accumulator value corresponding to the determined set of UL subframes to determine the power of the UL transmission when transmitting in the subframe of the UL transmission, where n is an integer and k Is an integer greater than zero.
