Claim of US Patent No. 10,716,136

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: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 one taken from the group consisting of (a) at least a first measurement cycle and (b) a second measurement cycle, one of:
while performing the measurements on at least one cell on a first secondary component carrier (SCC) with a deactivated first SCell using at least the first measurement cycle; and
while performing the measurements on at least one cell on a second SCC with a deactivated second SCell using at least the second measurement cycle; and
an allowed interruption on the PCell is:
up to one subframe if SCell and PCell are in different frequency bands; and
up to five subframes if PCell and SCell are in the same frequency band.
