摘要： A wireless transmission device enabled to improve an error rate performance at a receiver, by acquiring at least one of frequency diversity effect and a time diversity effect while keeping the interference resistance which is acquired by diffusion. In this transmission device, a modulation unit (101) modulates data to create a modulation symbol having in-phase components and quadrature components. An IQ individual spreading unit (102) arranges the diffusion chips, which are obtained by spreading the modulation symbol, of the in-phase components and the quadrature components, in areas extending in diffusion domains set individually for the in-phase components and the quadrature components. An IQ combining unit (103) combines the arranged spreading chips of the in-phase components and the quadrature components.

摘要： In a communication system that combines HDR system and IS-2000 system, when mobile station 101 receives an interruption request from IS-2000 system while performing high-speed packet communication system under HDR system, BTS 105 modifies priority of MS 101 higher than when there is no interruption request and assigns communication resources accordingly. By thus adequately operating HDR system and IS-2000 system, it is possible to offer a wireless communication system that efficiently combines the services of both systems, as well as a base station apparatus and a communication terminal for use in the system.

摘要： A server (191) transmits image information consisting of basic data and complementary data to a router (100) through the Internet (192). The router (100) allocates the basic data to a BS (110) of a cellular system (193) and the complementary data to an AP (120) of a wireless LAN system (194). The BS (110) transmits the basic data to a MS (150) and the AP (120) transmits the complementary data to the MS (150). When the MS (150) is located in the area of the cellular system (193), the MS always maintains a communication channel with the BS (110) and when the MS enters the area of the wireless LAN system (194), the MS also opens a channel with the AP (120) while maintaining the channel with the BS (110). This allows the user to continue seamless communication.

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.
