摘要： There is provided a mobile station device capable of effectively performing interference suppression symbol synthesis while suppressing the lowering of the transfer rate when using the repetition technique in multi-carrier communication. In the mobile station device (100), when the interference level exceeds a threshold value, a switching control unit (110) controls a switch (109) to connect a P/S unit (106) to a weight multiplication unit (113) and controls a switch (111) to connect a channel estimation unit (108) to a weight calculation unit (112). The weight calculation unit (112) calculates an interference suppression weight based on MMSE from a pilot symbol and a channel estimation value. The weight multiplication unit (113) multiplies a data symbol by the interference suppression weight. A synthesis unit (114) synthesizes the data symbol multiplied by the interference suppression weight in repetition unit.

摘要： A base station apparatus wherein the interference suppression symbol combination can be performed in a case of using the repetition technique in a multicarrier communication. In a base station (100), a repetition part (103) repeats or copies each of data symbols received from a modulating part (102) to create a plurality of same data symbols. A phase rotating part (106) imparts, in accordance with a phase rotation angle set by a setting part (107), phase rotations to the pilot and data symbols received from a multiplexing part (105). At this moment, the phase rotating part (106) imparts the phase rotations of the same angle to the pilot and data symbols assigned to the same subcarrier. Further, the phase rotating part (106) causes the phase rotation difference between the same data symbols in a cell to be different from the phase rotation difference between the same symbols in an adjacent cell.

摘要： A wireless communication method for improving the transmission efficiency in an upstream communication in OFDMA-TDD system or the like. An upstream transmission timing control part (108), which employs this method, controls, based on the OFDMA-TDD scheme, the transmission timings of a mobile station (#p) and a mobile station (#M) communicating with a base station (100). The upstream transmission timing control part (108) acquires information about the propagation delay times τp and τM of the mobile station (#p) and mobile station (#M). When the propagation delay time τp is shorter than the propagation delay time τM, the upstream transmission timing control part (108) decides the transmission timings of the mobile station (#p) and mobile station (#M) such that the timing at which the base station (100) starts receiving symbols from the mobile station (#p) in an upstream section is earlier, by αp times an OFDM symbol length (L) (where αp is a natural number), than the timing at which the base station (100) starts receiving symbols from the mobile station (#M) in the same section.
