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 system for encoding and decoding Medium Access Control (MAC) Protocol Data Units (PDUs) in a MAC layer packet is provided. The method includes receiving a request from a Physical (PHY) layer to transmit the MAC layer packet, wherein the MAC layer packet is transmitted in a predefined number of bytes that is determined in the PHY layer, and filling unfilled portion in the MAC layer packet with at least one fixed pattern in a predefined pattern set when a number of bytes that are unfilled is equal to or greater than 1. The unfilled portion includes total number of bytes that are unfilled in the MAC layer packet. Thereafter, the unfilled portion of the MAC layer packet is filled with a predefined pattern set when the number of predefined bytes is greater than the cumulative size of the available MAC PDUs arranged in the MAC layer packet.

摘要： An apparatus and method is provided for determining a serving sector using a signal received from a base station. A received signal strength measurer measures a strength of a pilot signal received from the serving sector and a strength of a pilot signal received from a sector in an active set. A controller then calculates a difference between the strength of the pilot signal received from the serving sector and the strength of the pilot signal received from the sector in the active set, updates selection parameters by comparing the calculated difference with a predetermined threshold, and selects a best serving sector from the active sectors in the active set using the updated selection parameters and comparative parameters. A memory can be implemented to store the parameters.

In one embodiment, a method of identifying a subscriber station from a quick access message includes receiving the quick access message from the subscriber station connected to a base station, where the quick access message includes a station identifier (STID) and a bandwidth request (BR) index assigned to the subscriber station. The method also includes determining whether the STID in the quick access message is assigned to multiple subscriber stations. Furthermore, the method includes identifying a subscriber station associated with the quick access message using the BR index in conjunction with the STID if the STID is assigned to the multiple subscriber stations. Moreover, the method includes performing an action identified by the BR index for the identified subscriber station in response to the quick access message.
