Abstract: A method is provided which improves reliability of channel estimation in a digital communication system by reducing the ambiguity in the recognition of received symbols evaluated for the channel estimation. A first plurality of bits is mapped to a modulation state according to a given Gray mapping of binary numbers to modulation states and transmitted. The plurality of bits is re-transmitted at least once, with a sub-set of bits contained in the plurality of bits inverted, and mapped to further modulation states according to the same Gray mapping. The bits to be inverted are determined in a way that the number of different vector sum results obtainable, for all combinations of bit values within the first plurality of bits, by adding vectors representing complex values of the first and further modulation states in a complex plane, is lower than the number of different modulation states within the Gray mapping.

Abstract: To improve the reliability of channel estimation, data symbols at determined positions of the transmitted data stream are replaced by quasi-pilot symbols. The quasi-pilot symbols carry data modulated onto the carrier with a different modulation scheme than the original symbols. The modulation scheme for the quasi-pilot symbols has a lower amplitude and/or phase ambiguity than the modulation scheme for the original data symbol.

Abstract: Disclosed are a radio communication base station device, a radio communication terminal device, and a radio communication method which can reduce interference between adjacent resource blocks even when the DL timing is overlapped with the UL timing at the boundary between an independent allocation band and a cooperation allocation band. When a terminal A is allocated for a UL resource block of the cooperation allocation band serving as a band boundary with the independent allocation band, in ST301, a terminal A transmits a horizontally polarized wave signal to respective terminals B to D, and in ST302, a base station (100) transmits a vertically polarized signal to respective terminals A to D. In ST303, the terminals B to D measure XPD of the received vertically polarized signal and the horizontally polarized signal. In ST304, the terminals B to D transmit the XPD report value to the base station (100). ST305 selects the terminal which has transmitted the largest XPD report value among the XPD report values transmitted from the terminals B to D and allocates the selected terminal to the DL resource block at the band boundary.

Abstract: It is possible to provide a transmission control method, a radio communication system, and a radio base station device which can reduce the time required until an inter-cell interference is reduced so as to improve the system throughput. A base station (200) includes: an FFT unit (210) which receives an interference report transmitted by using a common radio resource common to adjacent cells from a plurality of radio terminals (100) existing in different adjacent cells; and an adaptive FFR processing unit (230) which controls adaptive FFR processing in a downstream line of the local cell according to the reception interference report. Thus, by receiving an interference report directly from the radio terminals (100) existing in adjacent cells, it is possible to modify the transmission mode by considering the interference state in the adjacent cells. This eliminates the need of sending a report on a transmission mode modification which has been conventionally sent between adjacent base stations (200). This reduces the signaling required in the system, which improves the system throughput.
