摘要： A communication device which can reduce amount of control information, limit interference with other traffics, and prevent an increase in current consumption. In this device, a separation unit (105) separates radio resource allocation information, specific section information and transmission parameter information from a received signal. A specific section information control unit (106) selects a sub-carrier designated by the specific section information to allocate data to be transmitted to the own unit. A channel quality measuring unit (107) uses a pilot signal to measure the channel quality of the selected sub-carrier. A channel quality information creating unit (108) creates channel quality information indicating the measurement results input from the channel quality measuring unit (107). A multiplexing unit (109) multiplexes the transmission signal with the channel quality information.

摘要： In a MIMO system using a cross-polarized antenna structure, even if no ideal XPD can be obtained, the interference between different polarized waves can be reduced to allow an effective precoding to be executed. When a MIMO communication is performed between a transmitter (250) and a receiver (260) each using a cross-polarized antenna structure, a channel estimating and precoding selection section (214) of the receiver (260) performs a channel estimation of MIMO channels from the transmitter to the receiver, decides a precoding matrix (P) of a projection matrix for mutually orthogonalizing or substantially orthogonalizing the channel response matrixes for respective different polarized waves, and feeds the determined precoding matrix (P) back to the transmitter (250). In the transmitter (250), a precoding processing section (208) applies the precoding matrix (P) to the spatial stream corresponding to one of the polarized waves to perform a precoding, thereby allowing the transmitter (250) to transmit the polarized waves with the orthogonality therebetween maintained.

摘要： It is possible to obtain the diversity effect in a plurality of slots while preventing complication of a scheduler or inefficient use of resources, to eliminate the phenomenon in which SINR significantly decreases in a specific slot, and to avoid deterioration of demodulation performance. In a radio communication system which performs transmission in a sub-frame unit having two slots temporally continuously arranged, when pre-coding is performed by multiplying a signal to be output to a plurality of antennas by a pre-coding weight, CDD is used to shift a phase such that the phase in the pre-coding weight is cyclically changed on the frequency axis. The phase shift amount to be applied by the CDD is set to change by 2π in an allocated resource block (1RB) of the local device, and PVS is applied such that the phase shift amount differs by π between the weight W0 of the first half slot and the weight W1 of the second half slot in the sub-frame.
