Abstract
Enhanced MAC-es PDUs are created by concatenating enhanced MAC-es service data units (SDUs) based on higher layer PDUs and segments thereof where segmentation information is included in the enhanced MAC-es headers. An enhanced MAC-e header is generated for each enhanced MAC-es PDU to describe information about the enhanced MAC-es PDU. An enhanced MAC-e PDU is created by concatenating enhanced MAC-es PDUs and enhanced MAC-e headers. An enhanced MAC-es header may include a Transmit Sequence Number (TSN) field a Segmentation Description (SD) field length (L) fields to indicate the length of each enhanced MAC-es SDU and/or logical channel indicator (LCH-ID) fields. An enhanced MAC-e header may include one or more logical channel indicator (LCH-ID) fields for corresponding enhanced MAC-es PDUs or MAC-s SDUs and length (L) fields.

13. The method of claim 11, wherein the descriptor comprises a finish flag indicating the end of the descriptor.
14. A Node B configured to communicate an lub enhanced dedicated channel (E-DCH) data frame, the Node B comprising:
a processor configured to:
insert a plurality of enhanced medium access control (MAC-es) protocol data units (PDU) into the lub E-DCH data frame, each enhanced MAC-es PDU comprising at least one enhanced MAC-es service data unit (SDU) associated with a logic channel; and
insert, for each enhanced MAC-es PDU, a descriptor of the enhanced MAC-es PDU, wherein the descriptor is configured to identify the logic channel associated with the at least one enhanced MAC-es SDU; and
a transmitter configured to transmit the lub E-DCH data frame.
15. The Node B of claim 14, wherein the descriptor is configured to identify a length of the at least one enhanced MAC-es SDU.
16. The Node B of claim 14, wherein the descriptor comprises a finish flag indicating the end of the descriptor.
