摘要： A wireless communication base station apparatus that allows the number of times of blind decodings at a mobile station to be reduced without increasing the overhead caused by notifying information. In this apparatus, a CCE allocation part (104) allocates allocation information allocated to a PDCCH received from modulation parts (103-1 to 103-K) to a particular one of a plurality of search spaces that is corresponding to a CCE aggregation size of the PDCCH. A placement part (108) then places the allocation information in one of downstream line resources, reserved for the PDCCH, that is corresponding to the CCE of the particular search space to which the allocation information has been allocated. A radio transmission part (111) then transmits an OFDM symbol, in which the allocation information has been placed, to the mobile station from an antenna (112).

摘要： A radio transmission device capable of improving channel estimation precision for each frequency. In this device, an FFT unit (103) subjects a data signal to a Fourier transformation. A signal substitution unit (108) substitutes the frequency component of a portion of a plurality of frequency components composing the Fourier-transformed data signal, for a pilot signal. An IFFT unit (109) subjects the data signal, the frequency component of which has been partially substituted for the pilot signal, to an inverse Fourier transformation. A transmission RF unit (111) transmits the inversely Fourier-transformed data signal on a single carrier.

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.
