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.

摘要： It is possible to provide a base station device, a mobile station device, a communication system, a channel estimation method, a transmission antenna detection method, and a program which can employ PVS as the SCH transmission diversity method and avoid a side lobe to improve the adjacent cell search performance. When employing the PVS on the frequency axis of the SCH in these, different precoding weights are applied between sub carrier groups so as to correlate a plurality of PSC sequences to a precoding weight matrix and identify the PSC sequence. Moreover, the number of sub carriers to be allocated to sub carrier groups is correlated to the number of transmission antennas so as to detect periodicity of the self-correlation characteristic of a reception SCH signal, thereby identifying the number of transmission antennas.

摘要： It is possible to provide a novel pilot transmission method which can calculate an accurate channel estimation value, a MIMO transmission device using the pilot transmission method, and a MIMO reception device which performs communication with the MIMO transmission device. The MIMO transmission device (100) includes a cyclic shift processing unit (150) which cyclically shifts a first pilot signal sequence spread by a spread code 1 and second pilot signal sequence spread by a spread code 2 with different shift amounts. The first pilot signal sequence and the second pilot signal sequence which have been cyclically shifted are transmitted from different transmitting antennas at the same pilot transmission symbol section. Thus, by changing the shift amount of the cyclic shift process executed on each pilot signal sequence spread by the respective spread codes, it is possible to improve the pilot separation accuracy at a reception side. This enables more accurate calculation of a channel estimation value.
