Method and apparatus for reordering fragments within a MAC layer service data unit within a downlink frame

摘要

A method and apparatus for processes a downlink frame within a Medium Access Control (MAC) layer ( 348 ) where the downlink frame includes a plurality of fragments constituting one or more MAC Service Data Unit (MSDU)s. The MAC layer pre-processes the plurality of fragments of the downlink frame by reordering the fragments to reassemble one or more of the MSDUs ( 910 ) until an end-of-frame signal is detected ( 912 ). The end-of-frame signal indicates that all of the plurality of fragments for a downlink frame have been received. The MAC layer post-processes the plurality of fragments ( 916 ) in response to detecting the end-of-frame signal ( 912 ), then delivers the reassembled MSDUs to a next layer ( 918 ).
