Claim of US Patent No. 10,219,297

1. A method for a wireless device served by a first network node on a primary cell (PCell), the wireless device being capable of using at least two secondary serving cells (SCells), the method comprising:receiving a first request to perform a measurement on at least one cell on a first secondary component carrier (SCC) with a deactivated first SCell using at least a first measurement cycle;
receiving a second request to perform a measurement on at least one cell on a second SCC with a deactivated second SCell using at least a second measurement cycle;
ensuring that when transmitting packets between a serving cell and the wireless device, a serving cell interruption probability of a missed at least one of Acknowledgement (ACK) and Negative-Acknowledgement (NACK) signaling in the uplink (UL) direction does not exceed a determined effective serving cell interruption probability (Peff) of a missed at least one of ACK and NACK signaling in the UL direction, which is based on at least the first measurement cycle and the second measurement cycle, while performing the measurements on the cells of the first SCC and the second SCC; and
an allowed interruption on the PCell is up to one or five subframes.
