摘要
Systems, methods, and apparatus for performing measurement configuration using a user equipment, UE, and a network node are disclosed. An example method performed by a UE includes receiving a measurement configuration from a network node, where the measurement configuration specifies a reference frequency corresponding to a set of one or more carriers. The measurement configuration further specifies an offset from the reference frequency. The UE performs measurements on a reference signal located at the offset from the reference frequency and uses the measurements for one or more radio operations.
