摘要： It is possible to provide a radio communication system, a radio base station device, and a radio terminal device capable of reducing the power consumption in a radio terminal device without thinning pilot signals used for measuring upstream line quality. In the radio base station device (100) used in a radio communication system using different frequency bands for the upstream line and the downstream line, an upstream line pilot generation unit (115) forms a CQI measuring pilot signal and an upstream line RF unit (105) transmits the communication quality measuring pilot signal by using the upstream line use frequency band in the upstream line pilot transmission section. Thus, the upstream communication quality measuring pilot signal used by the radio base station device (100) to measure the line quality is transmitted by using the upstream line frequency band and accordingly, it is possible to reduce the power consumption in the radio terminal device.

摘要： The present invention makes it possible to obtain the transmission diversity effect by applying a CDD while reducing the inter-code interference when performing a code multiplexing. When an Ack/Nack signal is transmitted from a user terminal to a base station in an upstream control channel by using an Ack/Nack resource, the signal is code-multiplexed by using a code sequence containing an orthogonal sequence and a cyclic-shifted sequence and transmitted from a plurality of user terminals to the base station. Upon using an aggregation size indicating the number of control signals of the downstream control channel, if the aggregation size is greater than one, it is determined that no resource located at the right of the axis of the cyclic-shifted amount of the cyclic-shifted sequence in the same orthogonal code of the orthogonal sequence is used, and the Ack/Nack signal to which CDD is applied from a plurality of antennas is transmitted by using a resource ACK #0 allocated to the own device and an unused resource ACK #1, which have the same orthogonal code, but have different cyclic-shifted amounts.

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.

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.
