    Abstract: A radio communication apparatus is provided, which includes a receiver and a controller. The receiver, in operation, receives a first power headroom (PHR), which is obtained by subtracting a transmit power for a data channel from a maximum transmit power at a mobile station and which is transmitted from the mobile station, and receives a second PHR, which is obtained by subtracting the transmit power for the data channel and a transmit power for a control channel from the maximum transmit power at the mobile station and which is transmitted from the mobile station. The controller, in operation, selectively sets a simultaneous transmission of the data channel and the control channel in different frequency bands to be performed by the mobile station. When the data channel and the control channel are simultaneously transmitted in different frequency bands from the mobile station, the second PHR is obtained and transmitted from the mobile station.

    Abstract: A data alignment method capable of preventing degradation in demodulation performance due to variation in signal qualities when a data signal to which a Turbo code is applied is transmitted simultaneously from a plurality of cells. The method divides signal components to be used for data alignment into resources common to all the cells and resources dependent on the cells and transmits encoded and rate-matched data with the first half thereof aligned to the resources common to all the cells and the second half thereof aligned to the resources dependent on the cells.

    Abstract: A radio communication base station device can efficiently obtain a multiuser diversity gain from frequency scheduling while reducing the amount of a reference signal occupying an uplink. In the device, a grouping section divides a plurality of RBs (Resource Blocks) into a plurality of RB groups. An RB group control unit performs a control to change the correspondence relationship between the RBs and the RB groups with time. When the grouping section divides the RBs into the RB groups, the RB control unit performs a control to change a combination of the RBs included in each of the RB groups with time. A scheduling section performs a scheduling of allocating each of a plurality of mobile stations to each of the RBs in each of the RB groups according to the reception quality of the reference signal.

    Abstract: A wireless communication terminal apparatus wherein CoMP communication can normally be performed without increasing the overhead of an upstream line control channel. In this apparatus, a spreading unit primarily spreads a response signal by use of a ZAC sequence established by a control unit. A spreading unit secondarily spreads the response signal, to which CP has been added, by use of a block-wise spread code sequence established by the control unit. The control unit controls, in accordance with sequence numbers and a hopping pattern established therein, the circular shift amount of the ZAC sequence to be used for the primary spread in the spreading unit and the block-wise spread code sequence to be used for the secondary spread in the spreading unit. The hopping pattern established in the control unit is a hopping pattern common to a plurality of base stations that CoMP-receive the response signal.

    Abstract: In a base station, a control unit and a data size regulation unit control the data size of downstream assignment control data and upstream assignment control data in the PDCCH signal based on the communication format used between the base station and a terminal, the number of base station antennas (M) (nonnegative number), the number of terminal antennas (N) (nonnegative number), the bandwidth of the downstream band, and the bandwidth of the upstream band. Specifically, the control unit determines it is unnecessary to adjust the aforementioned data size when the selected communication format is first established between multiple antennas and when where there are multiple for one of M and N and only one for the other. The quality of downstream assignment control data is prevented from degrading, while preventing the number of blind determinations from increasing on the receiving side of the downstream control channel signal.

    Abstract: Disclosed is a wireless communication device that can suppress an increase in power consumption of a terminal while preventing the degradation of SINR measurement precision resulting from TPC errors in a base station. A terminal controls the transmission power of a second signal by adding an offset to the transmission power of a first signal; an offset-setting unit sets an offset correction value in response to a transmission time gap between a third signal transmitted the previous time and the second signal transmitted this time; and a transmission power control unit controls the transmission power of the second signal using the correction value.

    Abstract: Where first and second reference signals for a first and second communication system, respectively, are transmitted, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS for LTE-A, last half symbols in a time direction of a resource unit RB/Sub-frame defined in a frequency-time domain are used, and the CSI-RS is allocated in a position up to the last two symbols or in the last symbol, or the like, of a particular RB/Sub-frame and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in the last half symbol of RB/Sub-frame based on CSI-RS allocation information, measures channel quality by using this CSI-RS, and transmits and reports feedback information.

    Abstract: Disclosed are a wireless communication base station device and a division number determination method that improve the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit.
