WIRELESS COMMUNICATION METHOD AND APPARATUS FOR CONTROLLING THE TRANSMISSION POWER OF DOWNLINK AND UPLINK CODED COMPOSITE TRANSPORT CHANNELS BASED ON DISCONTINUOUS TRANSMISSION STATE VALUE

摘要

The present invention provides a wireless communication method and apparatus for controlling the power of signals transmitted by the downlink (DL) and / or uplink (UL) coded composite transport channels (CCTrCHs). The base station transmits signals to a wireless transmit / receive unit (WTRU) via the at least one DL CCTrCH, and, WTRU sends a signal to the base station via at least one UL CCTrCH. The base station determines whether or not discontinuous transmission (DTX) of a UL CCTrCH that controls the power of the DL CCTrCH, and is being used, the WTRU determines whether or not DTX of a DL CCTrCH is used for controlling the power of a UL CCTrCH. When DTX is used, the power of the CCTrCH is increased or decreased by a first step size, the second DTX is increased or decreased by the step size when not in use.
