摘要： A method for transmitting management message by a transmitting device in a communication network includes receiving a management message that is to be transmitted in the communication network. The transmitting device determines whether a feedback is required for the management message when the management message is transmitted in the communication network. The transmitting device also includes a feedback request information in a Medium Access Control (MAC) Protocol Data Unit (PDU) including a last fragment of the management message. The management message can be transmitted in one or more MAC PDUs and can be divided into one or more fragments. The transmitting device also transmits the MAC PDU indicating the feedback request information.

摘要： A method and device for performing an Automatic Repeat Request (ARQ) procedure in a wireless communication environment are provided. An initiation of the ARQ reset procedure is triggered by one of a transmitting device and a receiving device. A sequence number corresponding to a start of an ARQ window is determined. The sequence number is a sequence number of a first ARQ block to be transmitted by the transmitting device upon completion of the ARQ reset procedure. An ARQ reset message indicating the determined sequence number is transmitted to the receiving device. Accordingly, first and second pointer values of the ARQ window at the receiving device is set to the sequence number in the ARQ reset message. An ARQ reset acknowledgement message is sent to the transmitting device. Moreover, first and second pointer values of the ARQ window at the transmitting device is set to the determined sequence number.

摘要： 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.
