    Abstract: Provided is an apparatus and method for communicating a frame in a multi-hop relay cellular communication system. When communicating at a Relay Station (RS), a Downlink (DL) signal is received from a Base Station (BS) and the received DL signal is reconfigured during a first section of a frame. The reconfigured DL signal is transmitted to a Mobile Station (MS) during a second section of the frame. During a third section of the frame, a UL signal is received from the MS and is reconfigured. The reconfigured UL signal is transmitted to the BS during a fourth section of the frame. The RS recovers data from the BS to retransmit only specific data corresponding to the BS. Accordingly, unnecessary retransmission can be prevented and thus resources can be used efficiently.

    Abstract: The present invention provides a method and system for dynamically changing upper bound on size of data packets. In one embodiment, a transmitting device determines a need to change existing negotiated maximum size for an active connection when size of data packets for an application is switched, a new application is mapped to the active connection or Maximum Transmission Unit (MTU) of broadband wireless network is changed. Then, the transmitting device sends a request message indicating a new negotiated maximum size for changing the existing negotiated maximum size to the receiving device. The receiving device sends a response message confirming change to the new negotiated maximum size to the transmitting device. Accordingly, the transmitting device and the receiving device uses the new negotiated maximum size for building data packets and decoding the received data packets respectively based on a predefined parameter (e.g., sequence number/action time) indicated in the request/response message.
