    摘要: Provided are a radio transmission device and a radio transmission method, which prevent the deterioration of a preamble detecting performance while reducing the collision probability of a RACH. In this radio transmission device, a Signature table storage unit (103) divides the magnitudes of transmission loss levels into individual levels corresponding to the distances from a base station, to cause CAZAC series and circulation shift quantities to correspond to each other at the individual levels, and is provided with a table containing a plurality of Signatures created from the CAZAC series and the circulation shift quantities caused to correspond to each other. A Signature selecting unit (104) selects one of the corresponding Signatures at random from the Signature table storage unit (103), on the basis of the magnitude of the transmission loss level outputted from a transmission loss level deciding unit (102). A RACH signal generating unit (105) generates the RACH signal with the Signature selected.

    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).

    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.
