摘要:
An apparatus and method for supporting different frame structures in a broadband wireless communication system are provided. A communication method of a Base Station (BS) includes determining a frame structure to be provided. A MAP message including an indicator that indicates a new standard is generated, when the provided frame structure conforms to the new standard. The generated MAP message is transmitted by performing physical layer encoding thereon. Accordingly, signaling is defined to report a currently provided frame structure to an MS, and thus, a system can support different frame structures.

An apparatus and method for performing initial network entry in a broadband wireless communication system are provided. A communication method includes broadcasting, by a Base Station (BS), a Downlink Channel Descriptor (DCD) message including information on a different Frequency Allocation (FA) of the BS using all FAs; connecting, by one of a plurality of Media Access Control (MAC) processors of a Mobile Station (MS), using an arbitrary FA of the BS; obtaining, by the MS, information on the different FA of the BS by analyzing the DCD message received using the arbitrary FA; and performing, by one or more of the remaining MAC processors of the MS, a network entry process using the different FA of the BS according to the different FA information. Accordingly, when an MS having a plurality of MAC addresses connects to a system that performs communication through multiple FAs, different MAC processors of the MS can perform initial network entry using different FAs in the same cell (or sector or BS) without collisions.

An apparatus and method for performing handover in a broadband wireless communication system are provided. A communication method includes broadcasting, by a Base Station (BS), a neighbor advertisement message including neighbor cell information through each Frequency Allocation (FA); analyzing the neighbor cell advertise message by a plurality of Media Access Control (MAC) processors of an Mobile Station (MS) to obtain FA configuration information of each neighbor cell; independently determining handover by the MAC processors of the MS; generating the start of handover by one MAC which first determines handover; and determining a handover target by the remaining MAC processors so that handover is performed to different FAs of the same BS of the MAC processor which generates the start of handover by using the FA configuration information of each neighbor cell.

A handover method and apparatus for reducing a time delay during handover in a communication system is provided. A Mobile Station (MS) transmits a serving Base Station (BS) a first message indicating that the MS will perform handover to a target BS and the first message includes information for requesting a second message indicating a response to the successful receipt of the first message.

An apparatus and method for supporting a cooperative handover in a broadband wireless communication system. A method for operating a mobile station (MS) for a cooperative handover in a broadband wireless communication system includes determining a handover to a target BS and omitting a CID update process of the MS during the handover process to the target BS, wherein the CID of the MS is shared beforehand between a serving BS and the target BS.
摘要:
A method and apparatus allocates a Physical Cell Identifier (PCID) in a wireless communication system by considering a PCID reuse factor. An allowable PCID list is acquired from a server. A set of candidate PCIDs is determined from the allowable PCID list according to PCID allocation conditions. A received signal strength of each cell using the determined set of candidate PCID is determined. At least one PCID is selected by using a PCID reuse factor and the received signal strength of each of the cells using the determined set of candidate PCIDs.
