摘要： In DFT-s-OFDM, disclosed are a wireless transmission apparatus and wireless transmission method whereby freedom of allocation of frequencies is secured, while increases of CM are avoided. An SD number determination unit (152) determines an SD number based on the channel quality information of a mobile station and a threshold value that is set by a threshold value setting unit (151). A transmission bandwidth determination unit (153) determines the transmission bandwidth necessary for transmission of the transmission data. An allocation commencement position determination unit (154) determines the position for commencement of allocation of transmission data. If the SD number is equal to or more than the threshold value, a divided bandwidth determination unit (155) sets all the divided bandwidths to equal values and a frequency interval determination unit (156) sets all the frequency intervals to equal values.

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 transmission device and a radio communication method which can reduce inter-sequence interference and reduce the circuit size and the calculation amount even when RS is transmitted with different transmission bandwidths. Sequence length decision units (105) and (164) hold a correspondence in which one basic sequence length is set for a plurality of transmission bandwidths. The sequence length decision units (105) and (164) acquire transmission bandwidth information and decide a sequence length corresponding to the acquired transmission bandwidth information. Here, it is decided which of the cyclic extension process or the transaction process is to be executed on a ZC 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.
