Embodiments addressing MAC processing for efficient use of high throughput systems are disclosed. In one aspect, an apparatus comprises a first layer for receiving one or more packets from one or more data flows and for generating one or more first layer Protocol Data Units (PDUs) from the one or more packets. In another aspect, a second layer is deployed for generating one or more MAC frames based on the one or more MAC layer PDUs. In another aspect, a MAC frame is deployed for transmitting one or more MAC layer PDUs. The MAC frame may comprise a control channel for transmitting one or more allocations. The MAC frame may comprise one or more traffic segments in accordance with allocations.
