摘要： A handover method of a mobile station in a wireless mobile communication system and a system therefore are provided. The mobile station transmits a handover indication message to a serving base station, receives a ranging response message that comprises authentication information required for the mobile station to authenticate a target base station, receives fast ranging resources and transmits a ranging response acknowledgement (ACK) message, which comprises authentication information required for the target base station to authenticate the mobile station, to the target base station after receiving the fast ranging resources. Accordingly, a handover break time is minimized.

摘要： 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.

摘要： 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.

摘要： An apparatus and a method for data retransmission in a multihop relay wireless communication system are provided. The retransmission method includes determining whether an error is detected in data received from an upper node; generating a message indicative of the data error; and sending the message to the upper node at a time that is not appointed with the upper node. Therefore, it is possible to reduce a retransmission delay time that occurs during synchronous retransmission.

摘要： 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.
