Patent ID: 8483148

Claim:
A method implemented in a wireless transmit/receive unit (WTRU) for selecting a transport format combination (TFC), the WTRU being configured to process more than one channel for uplink transmission, the method comprising: estimating a transmit power for each of a plurality of available TFCs; selecting a TFC for an uplink dedicated channel (DCH) and a TFC for an enhanced uplink (EU) channel, wherein the TFC for the DCH is selected first, wherein the TFC for the DCH is selected based on a maximum allowed WTRU transmit power, wherein the TFC selection for the DCH is not affected by a power requirement for a TFC selection for the EU channel, and wherein the TFC for the EU channel is selected based on a WTRU transmit power remaining after the TFC selection for the DCH; and transmitting data over the DCH in accordance with the TFC selected for DCH and transmitting data over the EU channel in accordance with the TFC selected for the EU channel, the WTRU to scale down a transmit power for the channels for uplink transmission if the maximum WTRU transmit power is exceeded as a result of selecting the TFC for the EU channel.
