A media access controller (MAC) of a broadband wireless communication device may vary the size of data unit payloads based on a physical layer burst size. In automatic retransmission request (ARQ) enabled service flows, the MAC may delay construction of data units from the data unit payloads until after entering an ARQ retransmission request window. In some embodiments, the MAC comprises per-flow schedulers to schedule service data units (SDUs) for each of a plurality of service flows, and per-service flow retransmission request handlers to reconstruct and retransmit data units. |
