摘要： Provided is a radio communication device which can suppress inter-code interference between an ACK/NACK signal and a CQI signal which are code-multiplexed. A diffusion unit (214) diffuses the ACK/NACK signal inputted from a judgment unit (208) by using a ZC sequence. A diffusion unit (219) diffuses the CQI signal by using a cyclic shift ZC sequence. By using a Walsh sequence, a diffusion unit (216) further diffuses the ACK/NACK signal which has been diffused by using the ZC sequence. A control unit (209) controls the diffusion unit (214), the diffusion unit (216), and the diffusion unit (219) so that the minimum value of the difference between the CQI signals from a plurality of mobile stations and a cyclic shift amount of the ACK/NACK signal is not smaller than the minimum value of the difference between the cyclic shift amounts of the ACK/NACK signals from the plurality of mobile stations.

摘要： A sequence allocating method and apparatus wherein in a system where a plurality of different Zadoff-Chu sequences or GCL sequences are allocated to a single cell, the arithmetic amount and circuit scale of a correlating circuit at a receiving end can be reduced. In ST201, a counter (a) and a number (p) of current sequence allocations are initialized, and in ST202, it is determined whether the number (p) of current sequence allocations is coincident with a number (K) of allocations to one cell. In ST203, it is determined whether the number (K) of allocations to the one cell is odd or even. If K is even, in ST204-ST206, sequence numbers (r=a and r=N−a), which are not currently allocated, are combined and then allocated. If K is odd, in ST207-ST212, for sequences that cannot be paired, one of sequence numbers (r=a and r=N−a), which are not currently allocated, is allocated.

摘要： Techniques for generating a synchronization signal (e.g., a secondary synchronization signal) based on an M-sequence are described. In one design, first and second sequences for a secondary synchronization signal may be generated based on different cyclic shifts of the M-sequence. The cyclic shifts may be determined based on cell ID and/or other information to send in the secondary synchronization signal. An output sequence may be generated based on the first and second sequences, e.g., by combining the first and second sequences and scrambling the combined first and second sequences with at least one scrambling sequence. The secondary synchronization signal may then be generated based on the output sequence, e.g., by mapping samples in the output sequence to subcarriers and generating an OFDM symbol with the mapped samples. Detection for the secondary synchronization signal may be efficiently performed using fast M-sequence transform (FMT).
