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.

摘要： Provided are a radio transmission device and a radio transmission method which can reduce the transmission packet collision generation ratio even when a reception of scheduling information has failed in the retransmission method using a combination of the adaptive HARQ and the non-adaptive HARQ. In ST301, a resource control unit (206) stores resource allocation information and scheduling timing information transmitted from a base station (100). ST302 checks whether the scheduling information has been acquired. ST303 applies the adaptive HARQ. ST304 checks whether the scheduling information not acquired in ST302 has been acquired at the timing indicated by the scheduling timing information. In ST305, a resource control unit (206) instructs stop of the packet transmission. In ST306, the resource control unit (206) employs the non-adaptive HARQ.

摘要： A transmitting apparatus and a transmitting method wherein the systematic bit reception quality can be improved and the throughput performance can be improved. An IR parameter control part (101) controls, based on the number of retransmissions, the ratio of systematic bits to parity bits in mapping them to packets, and controls to map a parity bit to an initially transmitted packet, while mapping a systematic bit to a retransmitted packet. An encoding part (102) generates the systematic bits and parity bits and maps them to the packets in accordance with the IR parameters. A transmission power calculating part (105) calculates, based on reception quality information of the initially transmitted packet fed back from a receiving end, the transmission power of the transmitted packet to which the systematic bit is mapped. A transmission power control part (106) controls the transmission power of the retransmitted packet such that it is equal to the transmission power as calculated by the transmission power calculating part (105).
