Patent ID: 8259752

Claim:
A medium access control entity for enhanced uplink (MAC-e) in a wireless transmit/receive unit (WTRU), comprising: circuitry configured to transmit information regarding a volume of enhanced dedicated channel (E-DCH) data; circuitry configured to receive grant information in response to the transmitted information; circuitry configured to receive information from a radio access network indicating allowed combinations of medium access control for dedicated channel (MAC-d) flows that are allowed to be multiplexed into a MAC-e protocol data unit (PDU); in response to the received information indicating allowed combinations of MAC-d flows, circuitry configured to multiplex MAC-d flows into a MAC-e PDU based on the allowed combinations of MAC-d flows; circuitry configured to select a transport format combination (TFC) for transmission of the MAC-e PDU based on the received gant information; and a hybrid automatic repeat request (H-ARQ) entity configured to retransmit the MAC-e PDU in accordance with a transmission feedback.
