MAC multiplexing and TFC selection procedure for enhanced uplink
First Claim
1. A wideband code division multiple access (W-CDMA) frequency division duplex (FDD) user equipment (UE) comprising:
- a medium access control—
dedicated channel (MAC-d) configured to produce MAC-d flows for logical channels for transfer over an enhanced dedicated physical channel (E-DPCH);
an enhanced dedicated channel transport formal combination (E-TFC) selection device configured to receive a power offset and a serving grant and configured to select an E-TFC out of a plurality of supported E-TFCs, the plurality of supported E-TFCs having different granularities, the selected E-TFC is a largest supported E-TFC that does not exceed a size derived from the received serving grant and the provided power offset; and
a multiplexing device configured to receive the selected E-TFC and the MAC-d flows and configured to multiplex data of the MAC-d flows into an medium access control enhanced dedicated channel packet data unit (MAC-e PDU) having a size corresponding to the selected E-TFC.

Abstract
A method implemented in a wireless communication system including a wireless transmit/receive unit (WTRU), a Node-B and a radio network controller (RNC) for quantizing multiplexed data allowed by grants to closely match a selected enhanced uplink transport format combination (E-TFC) transport block size is disclosed. The amount of scheduled and non-scheduled data allowed to be transmitted is quantized so that the amount of data multiplexed into an enhanced uplink (EU) medium access control (MAC-e) protocol data unit (PDU) more closely matches the selected E-TFC transport block size. In an embodiment, the amount of buffered data allowed to be multiplexed by at least one grant, (a serving grant and/or a non-serving grant), is quantized so that the sum of scheduled and non-scheduled data including MAC header and control information multiplexed into a MAC-e PDU more closely matches the selected E-TFC transport block size.
