    摘要: An apparatus for transmitting data in a base station of a wireless communication system that transmits data depending on channel status information fed back from terminals and uses a plurality of antennas. Based on the channel status information, a scheduler determines a terminal to which the base station will transmit data, determines antennas via which the base station will transmit data among the plurality of antennas, and determines a space pre-coding method. A multiplexer multiplexes transmission data into a plurality of data streams according to the number of the determined antennas. A modulation and coding unit performs modulation and coding on each of the data streams. A pre-coding controller outputs a matrix select signal for selecting one of a plurality of space pre-coding matrixes according to the space pre-coding method. A space pre-coder spatial-codes each of the coded streams with the matrix selected based on the matrix select signal. An OFDM modulator performs OFDM modulation on each of the spatial-coded streams. An RF unit transmits each of the OFDM-modulated streams via an associated antenna.

    摘要: A method for supporting frequency hopping of a transmission apparatus by a reception apparatus in a wireless communication system supporting Hybrid Automatic Repeat reQuest (HARQ). The method includes determining whether a particular transmission apparatus has a need to perform hopping of allocating a different logical channel every Transmission Time Interval (TTI); and when there is no need to perform hopping every TTI, sending to the transmission apparatus a command to perform hopping every multiple TTIs, and simultaneously signaling information on a number of the multiple TTIs.
