    • 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.
      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.

    • 要解决的问题:提供一种在无线通信系统的用户站中的MAC和物理通信协议层之间发送和同步数据的方法。 解决方案:根据要发送的MAC分组的长度,本发明在映射到物理层时分段或级联MAC分组。 当MAC分组太长而不适合于一个TC / PHY分组时,MAC分组被分段,并且所得到的多个TC / PHY分组优选地在相同TDD帧内背对背地传输。 当MAC分组短于TC / PHY分组时,下一个MAC分组将与当前MAC分组连接成单个TC / PHY分组,除非应用异常(例如,上行链路中CPE的改变或调制变化 在下行链路上)。 当应用异常时,下一个MAC数据包在CTG或MTG之后的新TC / PHY数据包上启动。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To obtain a device for transmitting and synchronizing data between MAC and a physical communication protocol layer in a subscriber station of a wireless communication system.
      SOLUTION: Data are transmitted and synchronized between a media access control (MAC) and a physical communication protocol layer in a subscriber station. Depending on a length of MAC packets to be transmitted, the MAC packets are dissected out or linked together when mapping the MAC packets into a physical layer. When the MAC packets are too long, the MAC packets are dissected out and a plurality of TC/PHY packets is transmitted within the same TDD frame. When the MAC packets are short, the next MAC packets are linked together with the present MAC packets to be changed into a single TC/PHY packet. If an exception is applied, in the next MAC packets, CTG or MTG is started in the following new TC/PHY packets.
