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).
