    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: An apparatus and method for adjusting a data region to which data bursts are allocated in a broadband wireless communication system are provided. A cell load is calculated using information about data bursts to be transmitted and then compared with a predetermined threshold. A data region is adjusted based on the cell load such that a subchannel occupation rate is uniform over an entire data burst transmission time period, if the cell load is less than the threshold.

    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.

    摘要: An apparatus and method for setting transmit power of a compact Base Station (BS) in a wireless communication system are provided. In the apparatus and method a measurer measures a signal strength corresponding to each of one or more neighbor BSs while operating in a Mobile Station (MS) mode, a receiver receives a signal strength corresponding to each of the one or more neighbor BSs measured by one or more MSs from the corresponding one or more MSs, and a self-configuration controller sets a target signal strength based on the signal strength corresponding to each of the one or more neighbor BSs measured in the MS mode and controls a transmit power so that the signal strength corresponding to each of the one or more neighbor BSs measured by the one or more MSs substantially reaches the target signal strength.

    摘要: An apparatus and method for Forward link Outer Loop Rate Control (FOLRC) using Hybrid Automatic Repeat reQuest (HARQ) in a mobile communication system are provided. The method includes receiving information, which indicates success or failure in receiving a packet transmitted in a previous frame, from Mobile Stations (MSs); and decreasing an offset value for changing a CINR value in a link table of each MS when Acknowledgement (Ack) is received as the information indicating success or failure in receiving the packet, and increasing the offset value when a signal received as the information indicating success or failure in receiving the packet is other than the Ack. Accordingly, there is an advantage in that a link table adaptive to a channel condition can be obtained.
