    摘要： According to the present invention, there are provided an apparatus and a method that allow expansion of an estimable frequent offset range and correct estimation of a frequency offset. The apparatus of the present invention includes a frequency offset estimation unit (26A) that estimates the frequency offset by combining information on a maximum window having a maximum peak power obtained from a received PRACH (Physical Random Access Channel: physical random access channel) signal and a sign of a phase of a correlation value between channel estimation values obtained from a received PUSCH (Physical Uplink Shared Channel: physical uplink shared channel) signal.

    摘要： The quality of the transmission of HARQ-ACK/NACKs has to be higher in a MIMO multilayer communication system. In one embodiment, a wireless communication apparatus (10) includes a wireless communication unit (11) and a signal processing unit (12). The wireless communication unit (11) is configured to transmit plural multiple-input multiple-output (MIMO) layers using multiple antennas. The signal processing unit 12 is configured to map hybrid automatic repeat request (HARQ) responses onto some layers of the MIMO layers with a relatively high modulation and coding scheme (MCS), so that the HARQ responses are transmitted using only the some layers with a relatively high MCS.

    摘要： Base stations (100-1 to 100-3) communicate with terminals (102-1 to 102-2), divides a used frequency into a plurality of frequency blocks, and assigns the divided frequency block to terminal (102-1 to 102-2), in which a position at which terminal (102-1 to 102-2) exists is determined, and if it is determined that terminal (102-1 to 102-2) exists at the edge of cell (101-1 to 101-3), the assigned frequency block is set as a cell edge frequency block that is to be dynamically assigned at the edge of cell (101-1 to 101-3). In addition, if the cell edge frequency block has already been assigned to another terminal, this cell edge frequency block is assigned to terminal (102-1 to 102-2).
