PROBLEM TO BE SOLVED: To increase flexibility on SRS resource allocation, without increasing amount of signaling for notifying an amount of cyclic shift.SOLUTION: A receiver includes a reception part for receiving SRS series generated by applying cyclic shift, associated with any of N pieces of cyclic shift parameters, to a fundamental series, and a channel quality measurement part for measuring channel quality by using the SRS series. The SRS series is mapped onto a frequency resource, identified with a cyclic shift parameter and an antenna port identification number. A first correspondence relationship for defining a frequency resource associated with each of the antenna identification numbers, in a case the cyclic shift parameter is within 0 to(N/2)-1, is different from a second correspondence relationship for defining a frequency resource associated with each of the antenna identification numbers, in a case the cyclic shift parameter is within (N/2) to N-1.SELECTED DRAWING: Figure 5 |
