  • Publication number: 20260223048
    Abstract: A terminal includes: a control unit configured to expect mapping of resources corresponding to reference signals used for positioning to which frequency hopping is applied; and a reception unit configured to receive the reference signals, based on the expected mapping of resources. A first resource and a second resource corresponding to the reference signals are partially overlapped with each other in a frequency domain. The control unit expects a resource to be mapped to the second resource, based on an overlap size between the first resource and the second resource or based on a reference resource and an offset from the reference resource.
