    摘要： An apparatus and method for estimating a carrier to interference and noise ratio (CINR) in a mobile communication system based on a fractional frequency reuse are provided. The method includes receiving a report on CINR information on a common zone from a mobile station (MS) allocated a restricted zone, calculating a received signal power value using a CINR value and an interference level value for the common zone of the MS, and estimating a CINR value for a restricted zone using the received signal power value of the MS and an interference level for the restricted zone.

    摘要： An apparatus and method for circuit mode resource allocation in a Broadband Wireless Access (BWA) system is disclosed. The method includes generating a first resource allocation message which comprises currently used slot bitmap information with respect to a circuit mode region in a frame; allocating resources to one or more terminals with respect to currently unused slots in the circuit mode region according to the currently used slot bitmap information; and generating a second resource allocation message which comprises information relating to the resource allocation. Thus, the effective circuit mode resource allocation can be achieved without holes in the circuit mode, while maintaining backward compatibility with the existing standards.

    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.

    摘要： A method for increasing a network throughput of a cellular wireless packet network by controlling loading on a transmission frame in a cellular wireless packet network. In the method, transmission data are mapped to a transmission frame to be transmitted in a cellular wireless packet network in which a plurality of base stations and a plurality of mobile stations transmit packet data to each other. The method includes the steps of: dividing the transmission frame into a plurality of transmission groups each of which includes at least one slot; and constructing the transmission frame by allocating data with different loadings to the divided transmission groups.
