摘要： A rate matching apparatus is capable of improving the bit error rate characteristic at a data receiving end. A rate matching part (106), which serves as a rate matching apparatus, generates, from a first encoded block corresponding to N symbols (where N is an integer equal to or greater than one), a second encoded block corresponding to N+K symbols (where K is an integer equal to or greater than one). In the rate matching part (106), a to-be-divided bit-group extracting part (122) extracts, from the first encoded block, a first bit group corresponding to any of the N symbols. A dividing part (124) divides the extracted first bit group into L divided bit groups corresponding to L symbols (where L is an integer equal to or greater than two but equal to or smaller than K+1), thereby providing the second encoded block.

摘要： 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.

摘要： 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 data word transmitted according to a first mapping of data word values to modulation states is re-transmitted at least once with a second, re-arranged mapping of data word values to modulation states. The second mapping and possible further mappings are generated from the first mapping in a way that the number of different results which can be obtained from combining the transmitted original data symbol and the re-transmitted counterpart data symbol(s) is lower than the number of original modulation states in the first mapping.
