Method and apparatus for generating and processing MAC-ehs protocol data units

摘要

A network device and wireless transmit/receive unit (WTRU) using an enhanced high speed medium access control (MAC-ehs) are disclosed. A network device may provide a MAC-ehs reordering protocol data unit (PDU) with a segment of a service data unit (SDU). A MAC-ehs PDU is generated including the MAC-ehs reordering PDU. The MAC-ehs PDU is sent via a high speed downlink shared channel (HS-DSCH). The WTRU disassembles MAC-ehs PDUs to provide reordering PDUs that each may include a segment of a MAC-ehs SDU. The WTRU may reassemble a MAC-ehs SDU with the segment of the MAC-ehs SDU from at least one of the reordering PDUs.

1. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving, by the WTRU via a high speed downlink shared channel (HS-DSCH), enhanced high speed medium access control (MAC-ehs) protocol data units (PDUs); disassembling, by the WTRU at a MAC-ehs, the MAC-ehs PDUs to provide reordering PDUs, wherein at least one reordering PDU includes a MAC-ehs service data unit (SDU) or a segment of the MAC-ehs SDU; organizing, by the WTRU at the MAC-ehs, the reordering PDUs based on at least one transmission sequence number (TSN); reassembling, by one of a plurality of reassembly functions at the MAC-ehs, the MAC-ehs SDU from segments of the MAC-ehs SDU from at least one of the reordering PDUs, wherein the one of the plurality of reassembly functions is associated with a first plurality of logical channels and another of the plurality of reassembly functions is associated with a second plurality of logical channels; and routing the reassembled MAC-ehs SDU to a logical channel of the first plurality of logical channels.
