MAC multiplexing and TFC selection for enhanced uplink
First Claim
1. 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.

Abstract
A method and a wireless transmit/receive unit (WTRU) for multiplexing data for an enhanced dedicated channel (E-DCH) is disclosed. The WTRU receives 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. The WTRU determines supported enhanced dedicated channel transport format combinations (E-TFCs). The WTRU determines an enhanced uplink medium access control (MAC-e) protocol data unit (PDU) payload amount. For each logical channel, in order of priority, the WTRU multiplexes data from MAC-d flows associated with each logical channel into a MAC-e PDU, wherein each MAC-d flow is configured as either a scheduled MAC-d flow or a non-scheduled MAC-d flow, wherein on a condition that the MAC-e PDU payload amount is not equal to a supported E-TFC size, reducing the amount of data from a scheduled MAC-d flow to multiplex into the MAC-e PDU, based on a next smaller E-TFC size relative to the MAC-e PDU payload amount. The WTRU selects 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. The WTRU transmit the MAC-e PDU over the E-DCH processed in accordance with the selected E-TFC.
