摘要： Provided are a fixed station receiver for a Multi-Input Multi-Output (MIMO) communication system and an uplink adaptation method thereof. In the uplink adaptation method, a sounding reference signal (SRS) is received from a terminal including a plurality of transmission antennas. A complex channel matrix (H) corresponding to a channel response and a noise variance (σ2) corresponding to a noise power is calculated from the sounding reference signal. A signal-to-interference and noise ratio (SINR) on each transmission symbol is calculated with reference to the complex channel matrix (H) and the noise variance (σ2). A pre-coding matrix of the terminal is selected with reference to the signal-to-interference and noise ratio (SINR).

摘要： Provided are a method and apparatus for transmitting control information and packet data. The method includes generating control channels which transmit the control information; generating control indication channel which indicates whether the control channels are transmitted or not; generating data channels in order to transmit the packet data based on the control information; multiplexing the control channels, the control indication channels, and the data channels; and transmitting the control channels, the control indication channels, and the data channels. According to the present invention, when control information and packet data are transmitted in downlink, by transmitting additional information indicating whether control channels are transmitted or not, resources not actually allocated to control channels can be allocated to data channel and the mobile station can receive data channel using the control indication information.

摘要： The present invention relates to signal transmitting/receiving apparatuses. The signal transmitting apparatus includes an inverse discrete Fourier transform module, a cyclic prefix adding module, a preamble adding module, and a digital-analog converting module. The inverse discrete Fourier transform module receives modulated data, performs inverse discrete Fourier transform, and generates a first symbol. The cyclic prefix adding module adds a predetermined cyclic prefix to the first symbol, and generates a second symbol. The preamble adding module adds a predetermined preamble to the second symbol, and generates a third symbol. The digital-analog converting module converts the third symbol including the cyclic prefix and the preamble into an analog symbol.
