摘要： There is provided a multi-carrier communication method capable of preventing lowering of a throughput of another mobile device accompanying allocation of a sub-carrier for a new mobile station device. This multi-carrier communication method can acquire reception quality information for one of the sub-carriers already allocated in an MS (150a) from a BS (100a) and for one of the sub-carriers which can be allocated in the MS (150a) from the BS (100b). According to the reception quality information, a release sub-carrier is selected from the sub-carriers already allocated and a new-allocation sub-carrier is selected from the sub-carriers which can be allocated. The new-allocation sub-carrier has a frequency different from the already-allocated sub-carriers excluding the release sub-carrier. The BS (100a) is instructed to release the selected release sub-carrier and the BS (100b) is instructed to allocate the selected new-allocation sub-carrier in the MS (150a).

摘要： It is possible to provide a radio resource management device, a radio communication base station device, and a radio resource management method which can reduce a reply signal inter-cell interference and suppress decrease of the number of ACK/NACK which can be transmitted. When a plurality of CCE are allocated for PDCCH transmission, among usable CCE, the CCE number used between adjacent cells is differentiated. More specifically, a different RN satisfying RN=(usable CCE number m) mod N is allocated to the adjacent cell. A mobile station performs ACK/NACK transmission by using a PUCCH resource corresponding to the CCE number which becomes the allocated RN.

摘要： Provided is a terminal apparatus in which, a transmission control unit (204) controls the transmission power of a sounding reference signal (SRS) by use of an offset value relative to the transmission power of a data signal, and a transmission unit (206) transmits the SRS by use of the transmission power as controlled. If a subframe to be used for transmitting the SRS is a predetermined subframe, the transmission control unit (204) uses a first offset value to control the transmission power of the SRS. Otherwise, the transmission control unit (204) uses a second offset value to control the transmission power of the SRS. The second offset value is an offset value that has been established so as to be transmitted to the serving cell of the terminal (200), and the first offset value is greater than the second offset value.

摘要： The objective of the present invention is to provide a terminal device capable of suppressing delay in switching between transmit/receive points, and of reliably switching between the transmit/receive points. In the device, a reception processing unit (203) receives control information including a transmission request for an A-SRS and a report request for a downlink CSI, whereupon a transmission signal formation unit (207) transmits the A-SRS at a transmission power set on the basis of the report request. In addition, if a report for each downlink CSI between a plurality of base stations is requested in the report request, the transmission signal formation unit (207) transmits the A-SRS at a first transmission power, whereas if a report for a downlink CSI between a single cell is requested in the report request, the A-SRS is transmitted at a second transmission power. The first transmission power is greater than the second transmission power.

摘要： A scheduling apparatus and a scheduling method, wherein the amount of signaling for frequency resource allocation information can be reduced while maintaining system throughput performance. In a base station apparatus (100), a scheduling section (113) allocates frequency resources to frequency allocation target terminals based on set frequency allocation units, and a frequency allocation parameter setting section (112) adjusts the set frequency allocation units set in the scheduling section (113) based on cluster numbers. Due to this, in each cluster number, frequency resources can be allocated based on the most suitable frequency allocation units with respect to the signaling bit number. As a result, the amount of signaling for frequency resource allocation information can be reduced. Further, system throughput can be maintained by making the cluster number, which is a parameter having little effect on system throughput, a setting parameter for frequency allocation units.

摘要： A wireless communication base station apparatus which is able to prevent deterioration in the throughput of LTE terminals even when LTE terminals and LTE+ terminals coexist. In this apparatus, based on the mapping pattern of the reference signals used only in LTE+ terminals, a setting unit (105) sets, in each subframe, the resource block groups where the reference signals used only by the LTE+ terminals are mapped. For symbols mapped to the antennas (110-1 to 110-4), an mapping unit (106) maps, to all the resource blocks within one frame, cell specific reference signals used for both LTE terminals and LTE+ terminals. For the symbols mapped to the antennas (110-5 to 110-8), the mapping unit (106) maps, to the plurality of resource blocks, of which part of the resource block groups is comprised, in the same subframe within one frame, the cell specific reference signals used only for LTE+ terminals, based on the setting results inputted from the setting unit (105).
