Patent ID: 8553672

Claim:
A method for multiplexing data for an enhanced dedicated channel (E-DCH), implemented in a wireless transmit/receive unit (WTRU), the method comprising: receiving at least one serving grant and at least one non-scheduled grant, wherein the at least one serving grant is a grant for scheduled data transmission and the at least one non-scheduled grant is a grant for non-scheduled data transmission; determining supported enhanced dedicated channel transport format combinations (E-TFCs); determining an enhanced uplink medium access control (MAC-e) protocol data unit (PDU) payload amount; for a logical channel, based on priority, multiplexing data from a medium access control for dedicated channel (MAC-d) flow associated with the logical channel into a MAC-e PDU, wherein on a condition that the MAC-e PDU payload amount is not equal to a supported E-TFC size, multiplexing a reduced amount of data from the MAC-d flow into the MAC-e PDU, wherein the reduced amount of data from the MAC-d flow is based on a next smaller E-TFC size relative to the MAC-e PDU payload amount; selecting an E-TFC for transmission of the MAC-e PDU, wherein the selected E-TFC is a smallest E-TFC that supports the MAC-e PDU; and transmitting the MAC-e PDU processed in accordance with the selected E-TFC.
