Method and apparatus for prediction of a connection identifier in a downlink burst
View Patent ↗An apparatus for processing a downlink frame is provided which includes receiver circuitry ( 324 ), a physical layer processor ( 346 ) coupled to the receiver circuitry ( 324 ) and a MAC layer processor ( 348 ) coupled to the physical layer processor ( 346 ) is provided. The receiver circuitry ( 324 ) receives radio frequency (RF) signals and demodulates the RF signals to recover the downlink frame. The physical layer processor ( 346 ) processes the downlink frame to recover a plurality of MPDUs ( 704 ), each MPDU ( 500 ) including a CID ( 508 ). And the MAC layer processor ( 348 ) receives one of the plurality of MPDUs ( 806, 810 ) from the physical layer processor ( 346 ), processes it to recover its CID ( 812 ), and determines in response to the CID whether to process a next one of the MPDUs or whether to cease processing of the MPDUs ( 816 ).
