Abstract:
1. A method implemented in a wireless transmit/receive unit (WTRU) for uplink transmission using multiple uplink carriers, the method comprising: determining that more than one uplink carrier is activated; determining that a first uplink carrier is associated with a retransmission and a second uplink carrier is associated with a transmission; calculating a remaining power associated with the transmission by subtracting from a maximum allowed transmit power a power required for a dedicated physical control channel (DPCCH) power for each uplink carrier, a power required for a high speed dedicated physical control channel (HS-DPCCH), a power required for an enhanced dedicated channel (E-DCH) dedicated physical data channel (E-DPDCH) for the retransmission, and a power required for an E-DCH dedicated physical control channel (E-DPCCH) for the retransmission; calculating a normalized remaining power margin by: subtracting from the remaining power a power required for an E-DCH dedicated physical control channel (E-DPCCH) for the second uplink carrier, and dividing a result by a power required for a dedicated physical control channel (DPCCH) associated with the second uplink carrier; and performing an E-DCH transport format combination (E-TFC) selection.
