    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: Provided is a radio communication device which can prevent generation of mutual correlation peak between ZC sequences and reduce degradation of BLER characteristic of a CS-ZC sequence. In this device, a sequence length adjustment unit (103) truncates or extends the ZC sequence while maintaining the symmetry of the ZC sequence inputted from a ZC sequence generation unit (102) so as to adjust the sequence length to the number of subcarriers equivalent to the transmission bandwidth of a reference signal inputted from a sequence length setting unit (101). More specifically, the sequence length adjustment unit (103) truncates or extends any one of symbols constituting the ZC sequence so as to truncate or extend the ZC sequence. A transmission RF unit (107) transmits the ZC sequence after the sequence length adjustment.

    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.
