摘要： 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 (109) divides a plurality of RBs (Resource Blocks) into a plurality of RB groups. An RB group control unit (108) performs a control to change the correspondence relationship between the RBs and the RB groups with time. When the grouping section (109) divides the RBs into the RB groups, the RB control unit (108) performs a control to change a combination of the RBs included in each of the RB groups with time. A scheduling section (110) 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.

The device includes: a control unit (209) which controls a cyclic shift amount of a ZC sequence used for a primary diffusion in a diffusion unit (214) and a Walsh sequence used for secondary diffusion in a diffusion unit (217) according to a PUCCH number inputted from a judgment unit (208); the diffusion unit (214) which performs primary diffusion of the response signal by the ZC sequence set by the control unit (209); and the diffusion unit (217) which performs secondary diffusion of the response signal by the Walsh sequence set by the control unit (209). The diffusion unit (214) performs primary diffusion of the response signal by using the ZC sequence having such a cyclic shift amount that the guard interval at the both ends of the detection window section is maximum in the ZC sequences having different cyclic shift amounts.

摘要： It is possible to improve the CQI reception performance even when a delay is caused in a propagation path, a transmission timing error is caused, or a residual interference is generated between cyclic shift amounts of different ZC sequences. For the second symbol and the sixth symbol of the ACK/NACK signal which are multiplexed by RS of CQI, (+, +) or (−, −) is applied to a partial sequence of the Walsh sequence. For RS of CQI transmitted from a mobile station, + is added as an RS phase of the second symbol and − is added as an RS phase of the sixth symbol. A base station (100) receives multiplexed signals of ACK/NACK signals and CQI signals transmitted from a plurality of mobile stations. An RS synthesis unit (119) performs synthesis by aligning the RS phase of CQI.

摘要： In a terminal (200), a transmission control unit (206) identifies candidate resources on the basis of setting information and determines, on the basis of a trigger signal, a mapping resource, in which a second type of reference signal is mapped, in candidate frequency unit groups constituting the candidate resources. Each of the candidate resources is constituted by a plurality of fundamental subframe groups that are arranged at first intervals. N constituent subframes constituting each of the fundamental subframe groups are arranged at second intervals narrower than the first intervals. Each of the candidate frequency units of each candidate frequency unit group is a frequency unit specified by a predetermined frequency hopping pattern in M frequency units in each constituent subframe.
