Abstract:
1. A method for performing reassembly of a medium access control (MAC) protocol data unit (PDU) at a wireless transmit/receive unit (WTRU), the method comprising: receiving, at the WTRU, a value of a segmentation indication (SI) field in a MAC header associated with the MAC PDU, the SI field corresponding to a reordering PDU; and interpreting the value of the SI field at the WTRU, wherein the SI field having the value of “00” indicates that a first reordering SDU of the reordering PDU is a complete MAC enhanced high speed (MAC-ehs) SDU and a last reordering SDU of the reordering PDU is a complete MAC-ehs SDU, wherein the SI field having the value of “01” indicates that the first reordering SDU of the reordering PDU is a last MAC-ehs SDU segment and, if there are more than one reordering SDUs in the reordering PDU, the last reordering SDU of the reordering PDU is a complete MAC-ehs SDU, wherein the SI field having the value of “10” indicates that the last reordering SDU is a first MAC-ehs SDU segment and, if there are more than one reordering SDUs in the reordering PDU, the first reordering SDU of the reordering PDU is a complete MAC-ehs SDU, and wherein the SI field having the value of “11” indicates that, if there is one reordering SDU in the reordering PDU, the one reordering SDU is a middle MAC-ehs SDU segment, and if there are more than one reordering SDUs in the reordering PDU, the first reordering SDU of the reordering PDU is a last MAC-ehs SDU segment and the last reordering SDU of the reordering PDU is a first MAC-ehs SDU segment; and performing reassembly of the MAC PDU based on the interpretation of the value of the SI field.
