Abstract:
1. A wireless transmitting apparatus comprising: a sequence length determining section configured to determine a basic sequence length of a constant amplitude and zero-autocorrelation code (CAZAC) sequence associated with a transmission bandwidth indicated by acquired transmission bandwidth information, according to an association relationship between the basic sequence length of the CAZAC sequence and a plurality of transmission bandwidths to which the CAZAC sequence is allocated; a sequence generating section configured to generate a CAZAC sequence associated with the determined basic sequence length; and a transmitting section configured to transmit the generated CAZAC sequence as a reference signal, wherein: the association relationship (i) provides a grouping of the plurality of transmission bandwidths to which the CAZAC sequence is allocated into a plurality of transmission bandwidth groups, each transmission bandwidth group comprising at least a first transmission bandwidth and a second transmission bandwidth, and (ii) defines a first prime number that is nearest to and less than the first transmission bandwidth and a second prime number that is nearest to and less than the second transmission bandwidth, the first prime number and the second prime number being different from each other, and when the acquired transmission bandwidth information indicates the first transmission bandwidth, the sequence length determining section is configured to determine the sequence length having the second prime number, as the basic sequence length of the CAZAC sequence.
