无线发送装置和无线通信方法
摘要：
提供即使在以不同的发送带宽发送RS的情况下，也降低序列间的干扰，并且削减电路规模和运算量的无线发送装置和无线通信方法。序列长度决定单元(105)和序列长度决定单元(164)保持对于多个发送带宽设定了作为基本的一个序列长度(基本序列长度)的对应关系。序列长度决定单元(105)和序列长度决定单元(164)取得发送带宽信息时，决定与取得的发送带宽信息对应的序列长度。此时，基于取得的发送带宽信息与基本序列长度之间的大小关系，识别是对ZC序列进行循环扩张处理还是进行截断处理。然后，求发送带宽与基本序列长度之差、即可循环扩张/截断码元数。
摘要（英）：

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.
