Measurement on SCC SCell and on/off discovery signals
First Claim
1. A method of operation of a wireless device in a cellular communications network for determining whether to perform one or more measurements on a carrier with a deactivated cell, comprising:
- acquiring, by the wireless device, at least one parameter related to a periodicity, Dp, of a discovery signal transmitted on one or more cells of the carrier with the deactivated cell, where deactivated means turned off;
acquiring, by the wireless device, a measurement cycle parameter, Sc, for performing the one or more measurements on the one or more cells of the carrier;
comparing, by the wireless device, the periodicity, Dp, of the discovery signal and the measurement cycle parameter, Sc;
deciding, by the wireless device, to perform the one or more measurements on the one or more cells of the carrier only when at least one occasion of the discovery signal is time-aligned with at least one occasion of the measurement cycle parameter, Sc, as determined based on a starting time of the periodicity, Dp, of the discovery signal and the measurement cycle parameter, Sc; and
performing, by the wireless device, the one or more measurements on the one or more cells of the carrier.

Abstract
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).

21. A wireless device in a cellular communications network operable for determining whether to perform one or more measurements on one or more cells of a carrier with a deactivated cell that operates on a component carrier, comprising:
-
a transceiver module; a processing module; and a memory module storing software executable by the processing module, whereby the wireless device is operative to; acquire at least one parameter related to a periodicity, Dp, of a discovery signal of the deactivated cell on the carrier, where deactivated means turned off; acquire a measurement cycle parameter, Sp, for the one or more measurements on the one or more cells of the carrier; compare the periodicity, Dp, of the discovery signal and the measurement cycle parameter, Sc; decide to perform the one or more measurements on the one or more cells of the carrier only when at least one occasion of the discovery signal is time-aligned with at least one occasion of the measurement cycle parameter, Sc, as determined based on a starting time of the periodicity, Dp, of the discovery signal and the measurement cycle parameter, Sc; and perform the one or more measurements on the one or more cells of the carrier.
