摘要： A framing method of fixing a training signal and a control channel for multi-link (direct link and relay link) synchronization in a multi-hop relay cellular network, and a transmitting/receiving apparatus for supporting the framing method. A base station (BS) transmits BS downlink (DL) subframe sequentially including a preamble, control information, and a DL burst to a relay station (RS) or a first mobile station (MS) connected to the BS by direct link. The RS transmits an RS DL subframe sequentially including a DL burst, a postamble, and control information to a second MS connected to the BS by relay link. Therefore, difficulties of initial synchronization, handoff, and cell search can be removed from MSs. Furthermore, multi-link bursts can be located between the preamble and the postamble by Time Division Multiplexing (TDM) or Frequency Division Multiplexing (FDM).

摘要： Provided is an apparatus and method for constructing a subframe to support a multi link in a multi-hop relay cellular network. In a first section of a subframe, a subframe for communication with a mobile station (MS) is constructed, and in a next second section of the subframe, a subframe for communication with a relay station (RS) is constructed. Therefore, resources can be efficiently used without interference between subframes, pilots can be flexibly used, advanced technologies can be easily applied, and overhead due to RS switching gaps can be reduced.

摘要： Provided is an apparatus and method for constructing a frame for transmitting a direct link and a multi-hop relay link signal in one frame in a multi-hop relay cellular network. The signals are multiplexed on a time-division multiplexing basis and a base station downlink and relay station uplink subframe are located in a conventional downlink subframe. Accordingly, the overhead for a relay station receive transition gap in the downlink subframe and a relay station transmit transition gap in the conventional uplink subframe are eliminated.

摘要： In a communication system, a mobile station (MS) sends a target base station (BS) a notification indicating that it is to perform a handover from a serving BS to the target BS. The target BS transmits to the MS handover process optimization information indicating a possibility of omitting at least one process required by the MS to perform a network re-entry operation with the target BS according to the handover notification from the MS. The MS receives the handover process optimization information and performs a network re-entry operation with the target BS according to the handover process optimization information.

摘要： A method for controlling an idle mode in a broadband wireless access (BWA) communication system. A mobile station (MS) transmits to a base station (BS) a de-registration request (DREG-REQ) indicating a state transition request to the idle mode. The BS transmits to the MS a de-registration command (DREG-CMD) for commanding state transition to the idle mode. The MS transmits to the BS a de-registration acknowledgement (DREG-ACK) in response to the DREG-CMD.

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： A system and method in a mobile network in which a first router manages a first subnet including at least one second router and the at least one second router manages a second subnet including at least one mobile node. In a method for recovering a routing path between the first router and the at least one mobile node, the first router receives, from the at least one second router, information of neighboring routers included in the first subnet, and stores the received neighboring router information. An occurrence of routing path failure is recognized when a periodic report message is not received from the at least one second router within a preset time. An alternative router is selected from among the neighboring routers when the failure occurrence is recognized, and a routing path recovery request is sent to the alternative router. Data is routed to the at least one mobile node through the alternative router when the alternative router positively responds to the routing path recovery request.

摘要： A method and a system for periodic ranging in a sleep mode of a broadband wireless access communication system having an awake mode in which data to be transmitted between a mobile subscriber station (MSS) and a base station (BS) exists and the sleep mode in which data to be transmitted between the MS and the BS does not exist, the sleep mode having a sleep interval and a listening interval, the MSS being capable and incapable of receiving data in the listening interval and in the sleep interval, respectively. The BS reports to the MSS in a listening interval before the sleep interval that the MSS must perform the periodic ranging in the sleep interval when the BS detects that it is necessary for the MSS in the sleep mode to perform the periodic ranging at a particular time point in the sleep interval.
