摘要： Disclosed is a wireless communication apparatus and wireless communication method wherein flexible frequency scheduling is performed without increasing the scale of the DFT (Discrete Fourier Transform) circuitry. For example, when resource allocation information is reported indicating whether or not a resource has been allocated to each of a plurality of RBGs (RB groups) into which the system bandwidth is divided, as in Type 0 allocation, if the number of reported RBs reported by the resource allocation information cannot be expressed as “2^n×3^m×5^l”, an allocated RB number setting section (208) sets the number of allocated resource blocks used in the actual transmission band, corresponding to the reported RB number, to the number of resource blocks that can be represented by any of “2^n×3^m×5^l”, and an allocated RB selection section (209); selects the allocated RB employed in the actual transmission band from the resource allocation information and allocated RB number.

摘要： To suppress concentration of channel quality information requests and reports in a case of discontinuously transmitting reference signals at specific resources in a time domain, and thereby preventing degradation in throughput. A transmission apparatus (eNB) transmits an instruction of CSI request distributed for each reception apparatus in a subframe concurrently with or earlier than a reference signal CSI-RS to each of reception apparatuses (UE1, UE2). Each of the reception apparatuses (UE1, UE2) detects the CSI request from the transmission apparatus and calculates CSI from a channel estimation value of CSI-RS received thereafter. Then, the reception apparatus identifies CSI report subframe of the own apparatus from CSI report interval information of a given time interval notified in advance, the subframe in which the CSI request is detected and transmission timing of CSI-RS, and transmits a feedback signal including CSI report value by using PUSCH at the timing of the CSI report subframe.

摘要： Provided is a wireless communication terminal which, when SRSs are simultaneously transmitted between CCs and between antenna ports, avoids increasing the effect of bit rounding errors of D/A converters when the number of antenna ports set for SRS transmission differs between CCs. This device comprises a transmission power calculation unit (107) which calculates the transmission power of a plurality of UL channels of a plurality of CCs and a plurality of antenna ports. A power scaling detection unit (108) detects whether or not the total transmission power of the UL channels exceeds the maximum transmission power specific to a UE. When power scaling is generated, a power scaling control unit (109) uses antenna port setting information set for SRS transmission between CCs to perform power scaling in such a way that all scaling weights are uniform between CCs, or between CCs and between antenna ports.

摘要： A radio communication apparatus receives control information on one or more control channel elements (CCEs) with consecutive CCE number(s). The radio communication apparatus first-spreads a response signal with a sequence defined by a cyclic shift value that is determined among a plurality of cyclic shift values from an index of physical uplink control channel (PUCCH), which is associated with a first CCE number of the one or more CCEs, and second-spreads the first-spread response signal with an orthogonal sequence that is determined among a plurality of orthogonal sequences from the index. One of cyclic shift values used for an orthogonal sequence is determined from an index of the PUCCH, which is associated with an odd CCE number, and another one of the cyclic shift values used for the same orthogonal sequence is determined from an index of the PUCCH, which is associated with an even CCE number.
