摘要： A method and system for allocating a channel are provided in a communication system including a plurality of Mobile Stations (MSs) and Base Stations (BSs) for providing a communication service to the plurality of MSs. A BS transmits an average Channel Quality Information (CQI) request to MSs. The MSs measure CQI with respect to their channels in response to the request from the BS, compute average CQI from the measured CQI, and transmit the average CQI to the BS. The BS selects a predefined number of MSs according to the average CQI received from the MSs and sets an MS group. The BS transmits a CQI request to the MS group. The MSs of the MS group transmit the CQI to the BS. The BS receives the CQI from the MS group and allocates a channel according to the CQI.

摘要： A transmitter and a receiver are disclosed herein that support transmit antenna diversity using space-time block coding in a wireless communication system. The transmitter produces symbol combinations containing, as their elements, input symbols, the inversions and conjugates of the symbols, and symbols obtained by rotating the phases of the symbols once, forms a matrix having symbols in at least two columns orthogonal to each other with the symbol combinations, and transmits the matrix. The receiver detects symbols that minimize maximum likelihood (ML) decoding metrics over all possible symbols using channel gains from transmit antennas to a receive antenna. Also, the receiver selects candidate symbols among all possible symbols according to the characteristics of transmitted modulation symbols and detects symbols that minimize the ML decoding metrics.

The method includes a) setting a codeword length and the total number of bit nodes to be punctured; b) selecting a check node (or check nodes) with highest priority excluding check nodes completely checked in a current round; c) selecting a bit node (or bit nodes) with a highest priority excluding bit nodes completely checked among bit nodes connected to the selected check node (or check nodes); d) determining whether the selected bit node is a bit node to be punctured, that is, it is not systematic, not set by a puncturing prohibition flag; e) puncturing an associated bit node if the selected bit node is the bit node to be punctured, setting unpunctured bit nodes connected to the selected check node by a puncturing prohibition flag, decreasing the number of remained bit nodes to be punctured by 1 and increasing the number of connected punctured node of associated check node by 1; f) determining whether the number of remaining bits to be punctured is greater than 0; and g) returning to step b) if the number of remaining bits to be punctured is greater than 0, and ending a puncturing process if the number of remaining bits to be punctured is not greater than 0.

摘要： Frame structures, a method and an apparatus for resource allocation in a wireless communication system based on a full duplex relay are provided. The method for a centralized resource allocation in the wireless communication system based on the full duplex relay includes receiving channel information from a plurality of mobile stations (MSs) and relay stations (RSs); scheduling radio resources for a link between a base station (BS) and the MS and a link between the BS and the RS using the channel quality; constituting a first radio resource region for the link between the BS and the RS and a second radio resource region for the link between the BS and the MS; and scheduling radio resource for a link between the RS and the MS by reusing the first radio resource region. The relay link resource is reused in the full-duplex relay structure, and the system capacity can be raised by minimizing the interference in the resource utilization.
