<P>PROBLEM TO BE SOLVED: To provide a method of transmitting and synchronizing data between MAC and physical communication protocol layers in a subscriber station of a wireless communication system. <P>SOLUTION: Depending on the length of a MAC packet to be transmitted, the invention either fragments or concatenates the MAC packet when mapping to a 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 downlink). When an exception applies, the next MAC packet is started on a new TC/PHY packet following either a CTG or MTG. <P>COPYRIGHT: (C)2011,JPO&INPIT |
