Embodiment

[0041] 1. A method for generating a MAC-ehs PDU.

[0042] 2. The method of embodiment 1, comprising receiving a MAC-ehs SDU.

[0043] 3. The method of embodiment 2, comprising multiplexing the MAC-ehs SDUs based on a logical channel identity.

[0044] 4. The method according to embodiment 3, comprising generating a reordering PDU from the multiplexed MAC-ehs SDU, the reordering PDU comprising at least one MAC-ehs SDU and / or at least one MAC-ehs SDU segment , if the MAC-ehs SDU is not suitable for reordering PDUs, split the MAC-ehs SDU according to the priority level.

[0045] 5. The method of embodiment 3, comprising generating a MAC-ehs PDU comprising at least one reordering PDU.

[0046] 6. The method of any one of embodiments 3-5, wherein before generating the reordering PDUs, multiplexed MAC-ehs SDUs are stored in corresponding priority queues.

[0047] 7. The method according to any one of embodiments 3-5, wherein the reordering PDU is generated from the multiplexed MAC-...

Abstract

A method and apparatus for generating and processing a high speed downlink shared channel (HS-DSCH) medium access control (MAC-ehs) protocol data unit (PDU) are disclosed. MAC-ehs service data units (SDUs) are multiplexed based on a logical channel identity. Reordering PDUs are generated from the multiplexed MAC-ehs SDUs. A reordering PDU includes at least one MAC-ehs SDU and / or at least one MAC-ehs SDU segment. A MAC-ehs SDU is segmented on a priority class basis if a MAC-ehs SDU does not fit into a reordering PDU. A MAC-ehs PDU is generated including at least one reordering PDU. The MAC-ehs SDUs may be stored in priority queues before generating the reordering PDUs. Alternatively, the reordering PDUs may be generated from the multiplexed MAC-ehs SDUs. Alternatively, the received MAC-ehs SDUs may be buffered in a corresponding buffer for each logical channel before multiplexed based on a logical channel identity, or reordering PDUs are generated.

Description

technical field [0001] The present invention relates to wireless communications. Background technique [0002] High Speed ​​Packet Access (HSPA) evolution refers to the evolution of the 3rd Generation Partnership Project (3GPP) radio access technology of High Speed ​​Downlink Packet Access (HSDPA) and High Speed ​​Uplink Packet Access (HSUPA). Some of the main goals of HSPA evolution include higher data rates, higher system capacity and coverage, enhanced support for packet services, reduced latency, reduced operating costs, and backward compatibility. [0003] The Enhanced High-Speed ​​Medium Access Control (MAC-ehs) entity is extended to include, in addition to being able to receive variable-sized Radio Link Control (RLC) protocol data units (PDUs) A consensus has been reached on the functions to be used. The new additional functions of MAC-hs need to modify the traditional MAC-hs structure. [0004] Figure 1 shows a Universal Terrestrial Radio Access Network (UTRAN) si...
