Claim Text:
1. A method implemented in a wireless transmit/receive unit (WTRU) for transmitting pilot symbols on multiple antennas, the method comprising: transmitting an uplink primary dedicated physical control channel (DPCCH) and at least one uplink secondary DPCCH (S-DPCCH) via the multiple antennas using different channelization codes, wherein the S-DPCCH carries pilot symbols that are the same as pilot symbols of at least length eight of the primary DPCCH; transmitting an enhanced dedicated channel (E-DCH) dedicated physical data channel (E-DPDCH), wherein a normalized remaining power margin (NRPM) for an E-DCH transport format combination (E-TFC) selection is performed by taking a primary DPCCH transmit power, an S-DPCCH transmit power, a dedicated physical data channel (DPDCH) transmit power, a high speed dedicated physical control channel (HS-DPCCH) transmit power and an E-DCH dedicated physical control channel (E-DPCCH) transmit power into account; wherein power scaling is applied equally to the primary DPCCH and the S-DPCCH on a condition that a required transmit power exceeds a maximum allowed transmit power of the WTRU such that a power ratio between the primary DPCCH and the S-DPCCH remains the same after the power scaling; and wherein, when discontinuous transmission (DTX) is active, the WTRU does not transmit the S-DPCCH in a slot where the WTRU does not transmit the primary DPCCH.
