    摘要: Disclosed is a data transmission apparatus for providing transmission diversity in an SC-FDMA (Single Carrier-Frequency Division Multiple Access) system. The data transmission apparatus comprises: a data processor, which performs coding and modulation on an information bit to generate a data symbol; an SC-FDMA processor, which changes a weight matrix per change-cycle, precodes the data symbol for each weight matrix being changed and performs SC-FDMA modulation for generating an SC-FDMA symbol; and an RF unit, which transmits the SC-FDMA symbol. With the application of a PVS method to the SC-FDMA system, not only can transmission diversity be provided, but PAPR can also be reduced and single-carrier properties can be maintained.

    摘要: A method for transmitting a plurality of control information through a PUCCH or a PUSCH is disclosed. The method includes transmitting first control information, and transmitting second control information. The transmission of the first control information and the transmission of the second control information are performed in units of one subframe and are performed once per predetermined period, respectively. In a subframe in which the transmission of the second control information is to be simultaneously performed with the transmission of the first control information, the second control information is excluded for transmission or the first and the second information are simultaneously transmitted, according to the configuration of a closed-loop system or an open-loop system.
