摘要： Disclosed are a wireless communication method and device which can maintain frequency scheduling flexibility and improve system throughput performance. A Walsh sequence number determination unit (108) acquires Walsh sequence numbers used in each cluster according to a bandwidth notification order indicated by a plurality of RIVs, on the basis of associations between the bandwidth notification order indicated by the plurality of RIVs and Walsh sequence numbers used in each cluster. Furthermore, the Walsh sequence number determination unit (108) independently sets the acquired Walsh sequence number to each cluster multiplexed between two different terminals in the same bandwidth.

摘要： There are disclosed a wireless communication apparatus and a wireless communication method whereby a flexible frequency scheduling can be performed without increasing the circuit scale of DFT (Discrete Fourier Transform). In a terminal (200), a number-of-allocated-RBs setting unit (209) sets a number of allocated RBs, which is to be used for an actual transmission band corresponding to the number of notified RBs, to a number of resource blocks that can be expressed by one of “2n×3m×5l”. The allocated RB selecting unit (210) selects, based on the resource allocation information and the number of allocated RBs, either an unused one of the notified RBs that is not used as the transmission band or an additional RB that is added to the notified RBs and used as the transmission band.

摘要： Disclosed is a CCE+ number allocation method which reduces the ACK/NACK (Acknowledgment/Negative Acknowledgment) collision probability in a mixed system containing an LTE (Long Term Evolution) system and an LTE+ (Long Term Evolution Advanced) system. A CCE (Control Channel Element)+ number is defined by selecting a number from CCE numbers of the CCE to contain PDCCH (Physical Downlink Control Channel) allocated in a resource element region constituting CCE+ where PDCCH+ is arranged. This can prevent overlapped selection of the CCE number and the CCE+ number even when the PDCCH and the PDCCH+ are simultaneously transmitted. Thus, it is possible to reduce the collision probability of ACK/NACK correlated to the CCE number and the CCE+ number.

摘要： It is possible to obtain the diversity effect in a plurality of slots while preventing complication of a scheduler or inefficient use of resources, to eliminate the phenomenon in which SINR significantly decreases in a specific slot, and to avoid deterioration of demodulation performance. In a radio communication system which performs transmission in a sub-frame unit having two slots temporally continuously arranged, when pre-coding is performed by multiplying a signal to be output to a plurality of antennas by a pre-coding weight, CDD is used to shift a phase such that the phase in the pre-coding weight is cyclically changed on the frequency axis. The phase shift amount to be applied by the CDD is set to change by 2π in an allocated resource block (1RB) of the local device, and PVS is applied such that the phase shift amount differs by π between the weight W0 of the first half slot and the weight W1 of the second half slot in the sub-frame.

摘要： There is provided a wireless communication device capable of improving a decoding performance by using an optimal selection criterion for a start address and a read direction in a circular buffer. An interlacer (13) writes an interleaved and interlaced bit sequence into a circular buffer (14). An RV decision unit (109) decides the read start address and read direction of the circular buffer (14) based on the number of non-transmitted systematic bits, the number of non-transmitted important parity bits, and/or the number of non-transmitted unimportant parity bits. A read control unit (110) controls the read start address and read end address of the circular buffer (14). A read unit (15) is controlled by the read control unit (110) to continuously read encoded bits from the circular buffer (14).

摘要： A base station apparatus transmits control information to a radio communication apparatus on one or more control channel elements (CCEs) with consecutive CCE number(s) and receive a response signal from the radio communication apparatus. The response signal is spread with a sequence defined by a cyclic shift value that is determined among multiple cyclic shift values from an index of physical uplink control channel (PUCCH), which is associated with a first CCE number of aforementioned one or more CCEs, and with an orthogonal sequence that is determined among multiple orthogonal sequences from the index. One of cyclic shift values used for an orthogonal sequence is determined from an index of the PUCCH, which is associated with an odd CCE number and another one of the cyclic shift values used for the same orthogonal sequence is determined from an index of the PUCCH, which is associated with an even CCE number.

摘要： This invention relates to a transmitter apparatus, a receiver apparatus, a transmission method and a notification method that, when a switching between MIMO communication and non-MIMO communication is performed, can suppress the increase of an SRS (Sounding Reference Signal) resource, while suppressing the degradation of trackability of temporal variation of a channel. In a terminal (200), a mapping unit (212) maps an SRS sequence, which is received from a pilot, generating unit (216), on the basis of information related to an SRS hopping pattern, received from a base station (100). For this SRS hopping pattern, the frequency of the SRS transmissions via a first one of a plurality of antennas of the terminal (200) is higher than that of the SRS transmissions via a second one of the plurality of antennas of the terminal (200).
