The present disclosure relates to systems, methods, and devices for performing measurements on a carrier associated with a deactivated cell in a cellular communications system. In some embodiments, a method of operation for a wireless device for determining whether to perform one or more measurements on a carrier associated with a deactivated cell comprises acquiring at least one parameter related to a periodicity (Dp) of a discovery signal transmitted on one or more cells of a carrier with the deactivated cell, acquiring a measurement cycle parameter (Sc) for performing one or more measurements on one or more cells on the carrier, comparing the periodicity (Dp) of the discovery signal and the measurement cycle parameter (Sc), and deciding whether to perform the one or more measurements for the cells on the carrier based on the comparison of the periodicity (Dp) of the discovery signal and the measurement cycle parameter (Sc).
