CA 2727829

The present invention is a novel method and apparatus for efficiently transporting and synchronizing data between the Media Access Control (MAC) and physical communication protocol layers in a wireless communication system. Depending on the length of the MAC packet to be transported, the present invention either fragments or concatenates the MAC packet when mapping to the physical layer. When a MAC packet is too long to fit in one TC/PHY packet, the MAC packet is fragmented and the resultant multiple TC/PHY packets are preferably transmitted back-to-back within the same TDD frame. When a MAC packet is shorter than a TC/PHY packet, the next MAC packet is concatenated with the current MAC packet into a single TC/PHY packet unless an exception applies (e.g., a change in CPE on the uplink or a change in modulation on the downlink). When an exception applies, the next MAC packet is started on a new TC/PHY packet following either a CTG or MTG.
