METHOD AND APPARATUS FOR GENERATING AND PROCESSING A MAC-EHSPROTOCOL DATA UNIT

摘要

A method and apparatus for generating and processing a high speed downlin k shared channel (HS-DSCH) medium access control (MAC-ehs) protocol data uni t (PDU) are disclosed. MAC-ehs service data units (SDUs) are multiplexed bas ed on a logical channel identity. Reordering PDUs are generated from the mul tiplexed MAC-ehs SDUs. A reordering PDU includes at least one MAC-ehs SDU an d/or at least one MAC-ehs SDU segment. A MAC-ehs SDU is segmented on a prior ity class basis if a MAC-ehs SDU does not fit into a reordering PDU. A MAC-e hs PDU is generated including at least one reordering PDU. The MAC-ehs SDUs may be stored in priority queues before generating the reordering PDUs. Alte rnatively, the reordering PDUs may be generated from the multiplexed MAC-ehs SDUs. Alternatively, the received MAC-ehs SDUs may be buffered in a corresp onding buffer for each logical channel before multiplexed based on a logical channel identity, or reordering PDUs are generated.
