Patent ID: 8094682

Claim:
A method for use in a wireless transmit/receive unit (WTRU) for generating a radio link control (RLC) protocol data unit (PDU), the method comprising: receiving a data request for a logical channel as part of an enhanced dedicated channel (E-DCH) transport format combination (E-TFC) selection procedure in a medium access control (MAC); determining a data field size for the RLC PDU, wherein the data field size is determined such that the RLC PDU size of the RLC PDU is equivalent to the data requested for the logical channel by a current E-TFC selection, and wherein the RLC PDU size is less than a configured minimum RLC PDU size when data to be transmitted is insufficient to create a RLC PDU of the configured minimum RLC PDU size, and the RLC PDU size of the RLC PDU is greater than or equal to the configured minimum RLC PDU size when the data to be transmitted is sufficient to create a RLC PDU of the configured minimum RLC PDU size or greater; and generating the RLC PDU based on the determined data field size for transmission in a current transmission time interval (TTI).
