摘要： The wireless communication method used for transmitting interfering resource allocation information (IRAI) comprises a step of transmitting the IRAI through L1 signaling from the serving eNB to the victim UE, wherein the IRAI indicates only interfering resource block (RB) allocation within the bandwidth of RBs allocated to the victim UE at least in the case that the resource allocation type of the interfering UE is type 0, type 1, or type 2-L. The resource allocation type of the interfering UE can be signaled from the serving eNB to the victim UE within the downlink control information (DCI) of the victim UE for allocating resource. The indication mode of the IRAI for at least one interfering UE among the multiple interfering UEs that belong to a same interfering cell can be dependent on those interfering UEs whose IRAI has been indicated among the multiple interfering UEs.

摘要： Provided is a radio communication device which can prevent interference between SRS and PUCCH when the PUCCH transmission bandwidth fluctuates and suppress degradation of CQI estimation accuracy by the band where no SRS is transmitted. The device includes: an SRS code generation unit (201) which generates an SRS (Sounding Reference Signal) for measuring uplink line data channel quality; an SRS arrangement unit (202) which frequency-multiplexes the SRS on the SR transmission band and arranges it; and an SRS arrangement control unit (208) which controls SRS frequency multiplex so as to be uniform in frequency without modifying the bandwidth of one SRS multiplex unit in accordance with the fluctuation of the reference signal transmission bandwidth according to the SRS arrangement information transmitted from the base station and furthermore controls the transmission interval of the frequency-multiplexed SRS.

摘要： Provided is a sequence allocation method capable of reducing inter-cell interference of a reference signal when a ZC sequence is used as the reference signal in a mobile communication system. In the sequence allocation method, R×M sequences specified by a ZC sequence number r (r=1 to R) and a cyclic shift sequence number m (m=1 to M) are divided into a plurality of sequence groups X (X=1 to R) in accordance with the transmission band width of the reference signal, so that the ZC sequence is allocated to each cell in each sequence group unit. When it is assumed that R=9 and M=6, the number of sequences is 54. Each of the sequence groups is formed by two sequences. Accordingly, the number of sequence groups is 27. The 27 types of sequence groups are allocated to each cell.

摘要： A wireless base station apparatus and wireless terminal apparatus with a configuration which can prevent reductions in the accuracy of channel estimation when non-contiguous band transmission and SRS transmission are employed in an uplink line. In the base station apparatus (100), an allocation setting unit (106), which sets the reception band of an SRS at an SRS extraction unit (103) and sets the units of frequency allocation (RBG) at a CQ1 estimation unit (104) and allocation unit (105), matches the frequency position at the end of the SRS reception band to the frequency position at the end of any of the units of frequency allocation and sets the reception bandwidth of the reference signal to a natural number multiple of the bandwidth of the unit of frequency allocation. In the terminal apparatus (200), a band information setting unit (204), which sets the transmission band and units of frequency allocation (RBG), matches the frequency position at the end of the transmission band to the frequency position at the end of any of the units of frequency allocation and sets the transmission bandwidth of the SRS to a natural number multiple of the bandwidth of the unit of frequency allocation.

摘要： It is possible to provide a radio communication terminal device and a radio transmission method which can improve reception performance of a CQI and a reference signal. A phase table storage unit stores a phase table which correlates the amount of cyclic shift to complex coefficients {w1, w2} to be multiplied on the reference signal. A complex coefficient multiplication unit reads out a complex coefficient corresponding to the amount of cyclic shift indicated by resource allocation information, from the phase table storage unit and multiplies the read-out complex coefficient on the reference signal so as to change the phase relationship between the reference signals in a slot.
