    Abstract: A system and method for updating a sleep identifier (SLPID) of a mobile station (MS) in a broadband wireless access (BWA) communication system having a sleep mode in which there is no transmission data and an awake mode in which there is transmission data. Upon recognizing a need to update an SLPID allocated to an MS in the sleep mode in the initial phase of the sleep mode, a base station (BS) reallocates a new SLPID to be allocated to the MS and transmits SLPID update information to the MS. Upon receiving the SLPID update information for its current SLPID during the sleep mode, the MS updates its current SLPID with the reallocated SLPID according to the received update information.

    Abstract: Methods and apparatus are provided for performing a handover by a serving base station in a communication system. A handover request message is received from a mobile station. A first handover response message is transmitted to the mobile station. The first handover response message includes a list of at least one neighbor base station. A handover indication message including a value of a handover indication type field is received. The value is determined by the mobile station from among at least two values individually indicating at least one of a handover cancel and the handover rejection. The value representing the handover cancel indicates that the mobile station intends to cancel a handover procedure, and the value representing the handover rejection indicates that the mobile station intends to reject performing handover with any of the at least one neighbor base stations in the list.

    Abstract: An apparatus and method for configuring a Relay-Frame Control Header (R-FCH) transmitted in an intermediary link area in a multi-hop relay Broadband Wireless Access (BWA) communication system are provided. The method includes determining a modulation scheme of a Relay Station (RS) Downlink (DL)-MAP (or simply referred to as R-MAP) in consideration of a channel state with the RS while an initial network entry process is performed by the RS or while communicating with the RS in a Base Station (BS)-RS area where communication is made with RSs connected to the BS and transmitting a message including the determined modulation scheme to the RS. Accordingly, a Modulation and Coding Scheme (MCS) on the R-MAP can be dynamically changed according to a channel state between an RS and a BS, thereby enabling effective use of resources.

    Abstract: A system for transmitting/receiving resource allocation information in a wireless mobile communication system is provided. A transmission apparatus allocates a data burst in a frame, the data burst including a two-dimensional region of a time domain and a frequency domain, and transmits resource allocation information on the allocated data burst. A reception apparatus receives the resource allocation information from the transmission apparatus, and detects a region of the frame where the data burst is allocated, using the received resource allocation information. The resource allocation information includes information on a start point and an end point of the data burst. The start point indicates a point which is spaced apart from an start point of the frame by a first offset value in the time domain, and is spaced apart from the start point of the frame by a second offset value in the frequency domain. The end point indicates a point which is spaced apart from the start point by a third offset value in the time domain, and is spaced apart from the start point by a fourth offset value in the frequency domain. The data burst is a two-dimensional rectangular region having a diagonal line segment connecting the start point to the end point.
