MAC multiplexing and TFC selection procedure for enhanced uplink
First Claim
1. A method for multiplexing data implemented by a wireless transmit/receive unit (WTRU), the method comprising:
- receiving a serving grant, wherein the serving grant is a grant for scheduled data transmission;
receiving at least one non-scheduled grant, wherein the non-scheduled grant is a grant for non-scheduled data transmission;
determining an available payload amount for a medium access control for enhanced uplink (MAC-e) protocol data unit (PDU), wherein the available payload amount is the smaller of;
a maximum supported payload amount and a first amount of data, wherein the first amount of data is based on the serving grant and the at least one non-scheduled grant; and
multiplexing bits from a medium access control for dedicated channel (MAC-d) flow into the MAC-e PDU;
wherein the multiplexing is based on logical channel priority, wherein a higher priority logical channel is selected before a lower priority logical channel;
wherein on a condition that the selected logical channel is associated with a non-scheduled MAC-d flow, the MAC-e PDU is filled with bits from the non-scheduled MAC-d flow up to the smaller of;
an amount of data allowed by the non-scheduled grant for the non-scheduled MAC-d flow, an amount of data available for the selected logical channel, and the available payload amount; and
wherein on a condition that the selected logical channel is associated with a scheduled MAC-d flow, the MAC-e PDU is filled with bits from the scheduled MAC-d flow up to the smaller of;
an amount of data allowed by the serving grant, an amount of data available for the selected logical channel, and the available payload amount reduced by a quantization amount.

Abstract
A method and wireless transmit/receive unit (WTRU) for transmitting data over an enhanced uplink (EU) channel is disclosed. The WTRU receives a scheduled grant and at least one non-scheduled grant. The WTRU transmits a medium access control for EU channel (MAC-e) protocol data unit (PDU) over an EU channel. The MAC-e PDU includes multiplexed data. The multiplexed data includes scheduled data. An amount of the multiplexed data is not greater than a size of a largest supported EU transport format combination (E-TFC) size that does not exceed a size based on the received scheduled grant, the received at least one non-scheduled grant, and a power offset. The MAC-e PDU is transmitted based on a selected E-TFC. The selected E-TFC is a smallest E-TFC that supports the multiplexed data of the MAC-e PDU.
