    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 base station apparatus that can raise the usage efficiency of the frequency resources of the whole system in a multicarrier transmission. In this apparatus, a separating part (103) separates symbols received from a modulating part (102) into symbols to be assigned to a first subcarriers group and into symbols to be assigned to a second subcarriers group. A setting part (106-1) sets the transmission power of the symbols, which are to be assigned to the first subcarriers group, to a power value as calculated by a power calculating part (105), while a setting part (106-2) sets the transmission power of the symbols, which are to be assigned to the second subcarriers group, to a power value as calculated by the power calculating part (105). Thus, the transmission power control is differently performed between the symbols to be assigned to the first subcarriers group and the symbols to be assigned to the second subcarriers group.

When the device and the method are used: as the number of signature numbers allocated for UE by the network side increases, the condition for allocating a signature by UE itself is mitigated and an expectation value which is a statistic average value of the RA quantity using the signature allocated by UE for itself is decreased; and as the number of signature numbers allocated for UE by the network side decreases, the condition for allocating a signature by UE itself is limited and an expectation value of the RA quantity using the signature allocated by UE for itself is increased.
