Abstract:
A method and apparatus are described for controlling uplink (UL) transmission power. 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 that correspond to respective ones of the UL subframe sets. The WTRU may receive a TPC command in a subframe n of a downlink (DL) transmission, determine a subframe n+k of a UL transmission that the received TPC command corresponds to, determine which of the UL subframe sets the UL transmission subframe n+k belongs to, and adjust a TPC command accumulator value that corresponds to the determined UL subframe set to determine power of the UL transmission when transmitting in the UL transmission subframe, where n is an integer, and k is an integer greater than zero.
