RADIO TRANSMISSION DEVICE AND RADIO COMMUNICATION METHOD |
摘要 |
<p>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.</p> |
