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 “2̂n×3̂m×5̂l”, 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 “2̂n×3̂m×5̂l”, 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： Disclosed is a radio communication device that, even when a terminal erroneously receives a retransmission grant or a response signal from a base station, can reduce the number of other terminals in which the terminal interferes at a retransmission. In this device, a determination unit (205) determines a bandwidth between the two ends of a transmission band allocated to a transmitted signal at the retransmission of the transmitted signal. An allocation unit (209) allocates the transmitted signal to a frequency resource based on the bandwidth that is input from the determination unit (205). The determination unit (205) increases at the retransmission the amount of decrease in the bandwidth from the previous transmission, as the consecutiveness of the transmitted signal in the frequency region decreases.

摘要： A wireless communication apparatus enabling improved system throughput while limiting the amount of signaling for feedback information. In this apparatus, a setting unit (101) sets transmission power differently for each of a plurality of sub-packets obtained by dividing transmission data (transmission packet). Here, the setting unit (101) sets transmission power differently for each of the plurality of sub-packets so that the total transmission power for the plurality of sub-packets becomes the same as the transmission power that is allocated in advance to the transmission packet that constitutes the plurality of sub-packets. A dividing unit (102) divides the transmission data (transmission packet) into a plurality of sub-packets. Then, a transmitting wireless communication apparatus (100) transmits the plurality of sub-packets in order of sub-packets of higher transmission power (lower error rate).

In addition, a scheduling unit (118) schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit (117).
