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： A base station device causing no decrease in system throughput and guaranteeing the reception quality at a terminal when a DCI directed toward the terminal is mapped to a PDCCH region and an R-PDCCH region. A search space setting unit (103) sets a search space having a plurality of allocation candidates, in both regions.

摘要： The invention provides a base station that does not cause the number of blind decodings to be increased and further can prevent the flexibility of resource allocation from degrading. A search space setting unit (103) sets search spaces each of which is constituted by one or more control channel elements (CCEs) and each of which is to be decoded in the terminals and each of which is defined by a plurality of to-be-decoded candidates. An allocating unit (108) places, in one of the plurality of to-be-decoded candidates included in the search space, a control channel. The number of connections of CCEs constituting the to-be-decoded candidate is associated with the number of to-be-decoded candidates. The search space setting unit (103) causes, in accordance with the control channel to be transmitted, the association of the number of connections of CCEs constituting the to-be-decoded candidate with the number of to-be-decoded candidates to differ.

摘要： The objective of the present invention is to provide a transmitter device that is capable of preventing error detection of a data resource area as a result of a detection mistake of a control signal. In the device, a control unit (101) sets, as data resource areas, only PRBs that have been imparted with numbers greater than a number that has been imparted to a PRB for which has been set a control resource area for which a downlink assignment control signal (that is, a DL grant) has been mapped. In this manner, at a terminal (200), if the PRB for which a downlink assignment control signal has been detected can be identified, the data resource area can be identified directly, and therefore, it is possible to prevent error detection for the data resource area as a result of a detection mistake of an uplink assignment control signal.

摘要： A communication relay method and others are disclosed in which even when the channel quality varies, the communication data from MS can be relayed without degrading the throughput of the communication system. In this method, the channel quality between RS and BS is estimated (ST1010), and a determination criterion, which is used to determine whether to relay communication, is established based on the estimated channel quality (ST1020). More specifically, a severe determination criterion is set for a relay route having a bad channel quality between RS and BS, while a less severe determination criterion is set for a relay route having a good channel quality between RS and BS. On the other hand, the channel quality between MS and RS is also estimated (ST1030). Then, after both ST1020 and ST1030 are completed, the channel quality between MS and RS is compared to the determination criterion established in ST1020 to ultimately determine whether to relay the communication data from MS in ST1040.
