Apparatus and method for high-speed data communication in a mobile communication system with a plurality of transmitting and receiving antennas

摘要

An apparatus and method are provided for transmitting and receiving high-speed packet data without path loss in a mobile communication system with a plurality of transmitting and receiving antennas. To support high-speed data for a mobile station (MS), a base station (BS) identifies a correlation between the number of transmitting antennas and the number of receiving antennas using feedback information and determines whether to establish a relay transmission scheme. The BS determines if quality of service for the MS is satisfied when the number of transmitting antennas is grater than the number of receiving antennas according to the established relay transmission scheme. When the quality of service for the MS is not satisfied, the BS transmits the high-speed data through a specific node group adjacent to the MS.
