Wireless communication method and apparatus for controlling transmission power in coded composite transport channel of the downlink and uplink based on the status value of the discontinuous transmission

摘要

PROBLEM TO BE SOLVED: To control the power of signals transmitted by downlink (DL) and/or uplink (UL) coded composite transport channels (CCTrCHs).;SOLUTION: This method for controlling the power of signals makes a base station 110 transmit the signals to a wireless transmit/receive unit (WTRU) 115 via at least one DL CCTrCH, and/or the WTRU 115 transmit the signals to the base station 110 via at least one UL CCTrCH. The base station 110 determines whether or not discontinuous transmission (DTX) of a UL CCTrCH that controls the power of a DL CCTrCH is employed, and/or the WTRU 115 determines whether or not DTX of the DL CCTrCH that controls the power of the UL CCTrCH is employed. The power of the CCTrCHs is incremented or decremented by a first step size when DTX is employed, and by a second step size when DTX is not employed.;COPYRIGHT: (C)2008,JPO&INPIT
