Abstract: Provided is a base station capable of appropriately applying precoding to a PDCCH. At the base station (100), a precoding control unit (105) sets a precoding granularity, which indicates a period in which the same precoding is used, to multiple control channels respectively disposed in different time resources. A transmission unit (108) transmits signals of the multiple control channels to a terminal (200) on the basis of the set precoding granularity.

Abstract: The present invention adopts a configuration such that when cooperative reception by a plurality of base stations is not applied, a reference signal sequence determined from a selection baseline value corresponding to the number of a sequence group allocated to a cell belonging to the device in question is selected from among a plurality of selection baseline values as a reference signal sequence for non-cooperative reception, whereas when cooperative reception by a plurality of base stations is applied, a reference signal sequence determined from one or more intermediate selection baseline values set between two adjacent selection baseline values corresponding to the number of a sequence group allocated individually to a terminal device is selected among the plurality of selection baseline values as a reference signal sequence for cooperative reception differing from the reference signal sequence for non-cooperative reception.

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: A terminal and a communication method thereof whereby, even in a case of employing the asymmetric carrier aggregation system and further employing the MIMO transmission method for upstream channels, the error characteristic of control information can be prevented from being degraded. In the terminal, a transport signal forming unit forms transport signals by arranging, based on an arrangement rule, ACK/NACK and CQI in a plurality of layers. According to the arrangement rule, an error detection result is arranged, on a priority basis, in a layer that is different from a layer in which the channel quality information is arranged. In this way, the puncturing of CQI using ACK/NACK can be minimized, with the result that the error characteristic of control information can be prevented from being degraded.

Abstract: Provided is a cyclic shift sequence generation method which can prevent coming of an interference wave into a desired wave detection window even if a cyclic shift sequence has a high mutual correlation in different bandwidths, thereby improving a channel estimation accuracy in a base station. In this method, a cyclic shift sequence number to be allocated to a cell is decided in advance. Moreover, when the cyclic shift amount between cyclic shift sequences allocated in cells is Δ1 and the cyclic shift amount of the cyclic shift sequences allocated between the cells is Δ2, Δ1 and Δ2 are made different when generating a cyclic shift sequence.
