Abstract
Systems and methods for employing digital two-way cable MAC protocols for multi-user wireless communication systems. In one embodiment, a physical layer TDMA framing structure is provided to complement the MAC layer framing. A single MAC layer frame is divided into multiple physical layer frames. The physical layer frames are divided among frames dedicated to transporting data between MAC layer entities and frames dedicated to transporting physical layer control information. Constant delay in transmission through the physical layer is preserved.
