Provided is a radio communication device which can prevent generation of mutual correlation peak between ZC sequences and reduce degradation of BLER characteristic of a CS-ZC sequence. In this device, a sequence length adjustment unit (103) truncates or extends the ZC sequence while maintaining the symmetry of the ZC sequence inputted from a ZC sequence generation unit (102) so as to adjust the sequence length to the number of subcarriers equivalent to the transmission bandwidth of a reference signal inputted from a sequence length setting unit (101). More specifically, the sequence length adjustment unit (103) truncates or extends any one of symbols constituting the ZC sequence so as to truncate or extend the ZC sequence. A transmission RF unit (107) transmits the ZC sequence after the sequence length adjustment.

摘要:
A radio transmission device and a radio communication method employ sequence length decision units which hold a correspondence in which one basic sequence length is set for a plurality of transmission bandwidths. The sequence length decision units acquire transmission bandwidth information and decide a sequence length corresponding to the acquired transmission bandwidth information. A decision is made as to which of the cyclic extension process or the truncation process is to be executed on a Zadoff-Chu sequence according to the sizes of the acquired transmission bandwidth information and the basic sequence length. Then, a difference between the transmission bandwidth and the basic sequence length, i.e., the number of possible cyclic extension/truncation symbols, is obtained.
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 (112) 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 (113) reads out a complex coefficient corresponding to the amount of cyclic shift indicated by resource allocation information, from the phase table storage unit (112) 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.
