摘要： In a case where a second reference signal for a second communication system is transmitted in addition to a first reference signal for a first communication system, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS, DVRB resources in which a resource unit defined in a frequency-time domain is divided in a time direction and distributedly allocated at predetermined frequency intervals are used and CSI-RS is allocated in a resource ID of a part of DVRB resources and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in DVRM resources on the basis of DVRB setting information for CSI-RS, measures channel quality such as CQI, PMI or RI by using CSI-RS, and transmits and reports feedback information containing channel quality information to a transmission apparatus.

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).

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： A radio communication device capable of randomizing both inter-cell interference and intra-cell interference. In this device, a spreading section (214) primarily spreads a response signal in a ZAC sequence set by a control unit (209). A spreading section (217) secondarily spreads the primarily spread response signal in a block-wise spreading code sequence set by the control unit (209). The control unit (209) controls the cyclic shift amount of the ZAC sequence used for the primary spreading in the spreading section (214) and the block-wise spreading code sequence used for the secondary spreading in the spreading section (217) according to a set hopping pattern. The hopping pattern set by the control unit (209) is made up of two hierarchies. An LB-based hopping pattern different for each cell is defined in the first hierarchy in order to randomize the inter-cell interference. A hopping pattern different for each mobile station is defined in the second hierarchy in order to randomize the intra-cell interference.

摘要： Provided is a radio communication device which can suppress inter-code interference between an ACK/NACK signal and a CQI signal which are code-multiplexed. In this device, a diffusion unit (214) diffuses the ACK/NACK signal inputted from a judgment unit (208) by using a ZC sequence.
