MAC multiplexing and TFC selection procedure for enhanced uplink
First Claim
1. A method for multiplexing data for an enhanced dedicated channel (E-DCH), the method comprising:
- determining a first size of data associated with a serving grant, wherein the serving grant is associated with at least one dedicated channel medium access control (MAC-d) flow;
determining a second size of data associated with at least one non-scheduled grant by summing for each MAC-d flow associated with the at least one non-scheduled grant a size of its non-scheduled grant or a size of its available data;
determining a first sum of the first size of data, the second size of data, and a size of scheduling information;
multiplexing bits from the MAC-d flows and the scheduling information into a medium access control E-DCH (MAC-e) protocol data unit (PDU) having a size not greater than a largest enhanced dedicated channel transport format combination (E-TFC) that does not exceed the first sum, wherein the MAC-d flows are associated with at least one of the serving grant and the at least one non-scheduled grant;
selecting an E-TFC for transmission of the MAC-e PDU, wherein the E-TFC supports the size of the multiplexed bits and does not exceed the first sum; and
transmitting the MAC-e PDU.

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.
