A method in a wireless device, comprising: determining a carrier aggregation configuration for the wireless device; obtaining, based on the determined carrier aggregation configuration for the wireless device, an allowed interruption level on a first carrier frequency (505a, 505b, 605), the allowed interruption level comprising a maximum allowed number of impacted subframes, Received Signal Strength Indicator, RSSI, samples or RSSI symbols, a maximum allowed interruption time, or a X% probability of missed acknowledgement, ACK, or negative-acknowledgement, NACK; receiving, from a network node, an RSSI configuration, the RSSI configuration comprising: an RSSI window length, an RSSI window periodicity, a time offset to the beginning of the RSSI window, an RSSI bandwidth, or a channel Occupancy Threshold, for an RSSI-based measurement, the RSSI-based measurement comprising an RSSI for Licensed-Assisted Access, LAA, a channel occupancy measurement for LAA, or a WiFi RSSI, on one of the first carrier frequency and a second carrier frequency (510a, 510b, 610), wherein at least the second carrier frequency is comprised in unlicensed spectrum; and controlling one or more configuration parameters to control an amount of interruption on the first carrier frequency to meet the obtained allowed interruption level, wherein the controlled one or more configuration parameters comprise one or more of: a time offset delta between an RSSI window on the first carrier frequency and a measurement occasion on the second carrier frequency, wherein the time offset delta is controlled to be within a first threshold; a time offset delta between an RSSI window on the second carrier frequency and a measurement occasion on the first carrier frequency, wherein the time offset delta is controlled to be within a second threshold. determining a carrier aggregation configuration for the wireless device; obtaining, based on the determined carrier aggregation configuration for the wireless device, an allowed interruption level on a first carrier frequency (505a, 505b, 605), the allowed interruption level comprising a maximum allowed number of impacted subframes, Received Signal Strength Indicator, RSSI, samples or RSSI symbols, a maximum allowed interruption time, or a X% probability of missed acknowledgement, ACK, or negative-acknowledgement, NACK; receiving, from a network node, an RSSI configuration, the RSSI configuration comprising: an RSSI window length, an RSSI window periodicity, a time offset to the beginning of the RSSI window, an RSSI bandwidth, or a channel Occupancy Threshold, for an RSSI-based measurement, the RSSI-based measurement comprising an RSSI for Licensed-Assisted Access, LAA, a channel occupancy measurement for LAA, or a WiFi RSSI, on one of the first carrier frequency and a second carrier frequency (510a, 510b, 610), wherein at least the second carrier frequency is comprised in unlicensed spectrum; and controlling one or more configuration parameters to control an amount of interruption on the first carrier frequency to meet the obtained allowed interruption level, wherein the controlled one or more configuration parameters comprise one or more of: a time offset delta between an RSSI window on the first carrier frequency and a measurement occasion on the second carrier frequency, wherein the time offset delta is controlled to be within a first threshold; a time offset delta between an RSSI window on the second carrier frequency and a measurement occasion on the first carrier frequency, wherein the time offset delta is controlled to be within a second threshold. a time offset delta between an RSSI window on the first carrier frequency and a measurement occasion on the second carrier frequency, wherein the time offset delta is controlled to be within a first threshold; a time offset delta between an RSSI window on the second carrier frequency and a measurement occasion on the first carrier frequency, wherein the time offset delta is controlled to be within a second threshold.
