MAC multiplexing and TFC selection procedure for enhanced uplink

A wireless transmit/receive unit (WTRU) comprising:

• a receiver configured to receive a scheduled grant and at least one non-scheduled grant, wherein the scheduled grant is a grant for scheduled data transmission and the at least one non-scheduled grant is a grant for non-scheduled data transmission;
• a transmitter configured to transmit a medium access control for enhanced uplink (EU) channel (MAC-e) protocol data unit (PDU) over an EU channel;
• wherein the MAC-e PDU includes multiplexed data;
• wherein the multiplexed data includes scheduled data;
• wherein 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;
• and
• wherein the MAC-e PDU is transmitted based on a selected E-TFC, wherein the selected E-TFC is a smallest E-TFC that supports the multiplexed data of the-MAC-e PDU.

A method for transmitting data over an enhanced uplink (EU) channel implemented by a wireless transmit/receive unit (WTRU), the method comprising:

• receiving a scheduled grant and at least one non-scheduled grant, wherein the scheduled grant is a grant for scheduled data transmission and the at least one non-scheduled grant is a grant for non-scheduled data transmission;
• transmitting a medium access control for EU channel (MAC-e) protocol data unit (PDU) over an EU channel;
• wherein the MAC-e PDU includes multiplexed data;
• wherein the MAC-e PDU includes scheduling information;
• wherein the multiplexed data includes scheduled data;
• wherein 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, a power offset, and a size of the scheduling information;
• and
• wherein the MAC-e PDU is transmitted based on a selected E-TFC, wherein the selected E-TFC is a smallest E-TFC that supports the multiplexed data of the MAC-e PDU.
