A circuit includes a controller to determine whether to prohibit entry of an end unit to a base station in a wireless communication network, the controller con figured to process a media access control (MAC) management message that includes a timer value, the timer value designating a time period during which entry is prohibited.

A method for allocating resources by a Base Station (BS) in a wireless communication system is provided. The method includes determining use/nonuse of each of a plurality of Resource Blocks (RBs), which are allocated using a persistent allocation scheme, and transmitting resource allocation information indicating use/nonuse of each of the plurality of RBs to a plurality of Mobile Stations (MSs) according to a result of the determination.

Method and apparatus for allocating resources in a wireless communication system

An apparatus and method for providing selective Hybrid Automatic Repeat reQuest (HARQ) for a ranging service in a wireless communication system are provided. A HARQ method includes transmitting, to at least one Mobile Station (MS), ranging code division information, and if a ranging code is received from the MS, allocating the MS a resource considering the ranging code, and if a ranging signal is not received through the resource allocated to the MS, making a request for retransmission of the ranging signal to the MS.

Apparatus and method for providing HARQ for ranging in a wireless communication system

A network includes a Mobile Station (MS) for sending a Service Flow (SF) modification request message to a Base Station (BS) to modify an SF. The BS sends a path modification request message to a serving SF Authorization (SFA) when there is the information on the SF. The BS also sends an SF modification response message comprising a Confirmation Code 'Reject SF not found' to the MS when there is no information on the SF. The serving SFA sends a resource reservation request message to an anchor SFA when there is the information on the SF, and sends a path modification response message comprising a Failure Indication (FI) 'Requested Context Unavailable' to the BS when there is no information on the SF. The anchor SFA sends a resource reservation response message comprising the FI &#x2018;Requested Context Unavailable&#x2019; to the serving SFA when there is no information on the SF.

Apparatus and method for handling error for service flow modification a broadband wireless communication network

A method and apparatus for transmitting and receiving resource allocation information in a communication system are provided, in which a Base Station (BS) transmits resource allocation information including a folding bitmap and a Zone Flag (ZF). The folding bitmap provides zone configuration information about zones included in a subframe and the ZF indicates whether a last zone of the zones is allocated as a first service zone or a second service zone. The first service zone carries data for a first service, the second service zone carries data for a second service, and each of the first and second services zones includes at least one resource unit.

Apparatus and method for transmitting and receiving resource allocation information in a communication system

A method and an apparatus for recognizing a Multicast and Broadcast Service (MBS) region in a broadband wireless communication system are provided. In the method, whether a next MBS MAP message transmission point of a first frame and an MBS data burst transmission point indicated by MBS burst assignment information of a second frame match with each other in a third frame is determined. When matching with each other in the third frame, a control message including information for determining a starting point of an MBS region is generated. The generated control message is transmitted during one of the first and second frames.

Method and apparatus for recognizing multicast and broadcast service region in broadband wireless communication system

A method and an apparatus are configured to support a plurality of Media Access Control (MAC) versions in a broadband wireless communication system. An operating method of a terminal to support the multiple MAC versions in the broadband wireless communication system includes receiving a message comprising information of one or more MAC versions supported by a base station, from the base station; and sending information of one or more MAC versions supported by the terminal, to the base station using a message. Thus, in the wireless environment where the multiple MAC versions are mixed, the MAC version can be matched.

Method and apparatus for supporting multiple MAC versions in broadband wireless communication system

An apparatus and method for supporting Hybrid Automatic Repeat reQuest (HARQ) for an anonymously allocated bandwidth in a broadband wireless communication system are provided. The method of a terminal includes obtaining classification information of HARQ support ranging codes from a message received from a base station, to request an anonymously allocated resource, transmitting one of the HARQ support ranging codes, receiving a resource allocation message including HARQ related information and anonymous resource allocation information, and transmitting one of a ranging request message and a bandwidth request header according to the resource allocation information.

Apparatus and method for supporting hybrid automatic repeat request for anonymously allocated bandwidth in broadband wireless communication system

An apparatus and method for controlling sleep cycle synchronization of a sleep mode in a wireless communication system are provided. A method of operating a Mobile Station (MS) in a sleep mode state includes, if a traffic indication message and unicast data are not received during a listening window, transmitting one of a request message and a header to a Base Station (BS) to request a location of a next-scheduled listening window, and if a response for the one of the request message and the header is received, performing synchronization for a next sleep cycle.

Apparatus and method for controlling sleep cycle synchronization of sleep mode in wireless communication system

A switching method and apparatus in a broadband wireless communication system is provided. A method of an Advanced Base Station (ABS) for a Multicast Broadcast Service (MBS) in the broadband wireless communication system includes transmitting to an Advanced Mobile Station (AMS) a message including identification information for a primary carrier that provides the MBS among multiple carriers supported by the ABS, switching to the primary carrier with respect to the AMS, and transmitting MBS data through the primary carrier.

Switching method and apparatus in broadband wireless communication system

A method and apparatus for transmitting/receiving a connection identification (CID) in a communication system is provided. Upon detecting a need for its handover, a mobile station (MS) transmits a handover request message to a first base station (BS) in communication with the MS. Upon receiving the handover request message, the first BS transmits at least one CID for connection setup to a second BS to which the MS will perform handover, to the MS along with a handover response message in response to the handover request message. The MS receives the CID through the handover response message.
