Abstract
Methods and apparatus for avoiding power scaling and controlling transmit power in uplink data transmission are provided. If a user equipment (UE) would be transmit-power limited when transmitting data concurrently on an uplink high speed dedicated physical control channel (HS-DPCCH) and an uplink data channel, the UE may forgo building data for transmission on the uplink data channel to avoid power scaling. If the UE would be transmit-power limited when transmitting data concurrently on an HS-DPCCH and a dedicated physical control channel (DPCCH), the UE may reduce the transmission power of a portion of the data transmitted on the DPCCH to avoid power scaling. The UE may also boost transmission power of a negative acknowledge transmission above network-specified power level.
