摘要： A method and system for performing an inter-FA handover in a communication system are provided. An MS receives from a serving BS neighbor BS information including a BS ID of at least one neighbor BS and a reference signal index of a reference signal used in the at least one neighbor BS. When it is necessary to scan the reference signal from the at least one neighbor BS, the MS scans the reference signal corresponding to the reference signal index. If the scanned reference signal has a quality equal to or greater than a threshold, the MS determines the BS ID of the at least one neighbor BS using the reference signal index as a BS ID for a recommended neighbor BS available for the inter-FA handover.

摘要： A method for supporting a handover in a broadband wireless access communication system including an MSS, a serving BS providing service to the MSS, and a plurality of neighbor base stations, in which each of the BSs includes cells using different sub-channel bands. The method includes: measuring, by the BSS, intensities of signals received from the BSs, transmitting to the serving BS a request for a handover based on the measured signal intensities, establishing a connection with a target BS, to which a handover of the MSS is requested, from among the neighbor BSs before terminating a connection with the serving BS, and performing a soft handover by establishing a simultaneous connection with the two BSs in a handover area. The serving BS and the target BS allocate the same sub-channel including the same sub-carriers to the MSS when the mobile subscriber station performs the soft handover.

摘要： A method for transmitting common control information from a base station to a plurality of subscriber stations in a wireless communication. The common control information includes first information transmitted in common to all of the subscriber stations and second information separately transmitted to the subscriber stations according to channel states of the subscriber stations. The first information is transmitted using an MCS (Modulation and Coding Scheme) level having a modulation scheme with a lowest order and a coding scheme with a lowest coding rate among all MCS levels available in the base station. The second information is transmitted using MCS levels that are adjusted by a predetermined level against MCS levels corresponding to channel states of the subscriber stations.

摘要： A wireless communication system that divides an entire frequency band into a plurality of subcarrier bands and includes a plurality of subchannels, each of which includes a number of subcarrier bands. The number of subcarrier groups is equal to the number of the base stations included in the system and are generated by classifying the subcarrier bands in a period. For a particular base station, corresponding subcarrier bands are detected from each of the groups according to a sequence. The subcarrier bands detected from each of the groups are assigned as a subchannel for the particular base station. Further, the indexes of the subcarrier groups to which each of subcarriers constituting a subchannel belongs are changed whenever the subchannel is assigned, so as to acquire the desired diversity gain.
