Claim of US Patent No. 10,462,805

1. An apparatus, comprising:a cellular processor configured to conduct wireless communications according to a first radio access technology (RAT) in a first frequency band and in a second frequency band, wherein the first RAT is a cellular RAT, the first frequency band is in an unlicensed spectrum, and the second frequency band is in a licensed spectrum;
a wireless local area network (WLAN) processor configured to conduct wireless communications according to a second RAT in the first frequency band, wherein the second RAT is a wireless local area network (WLAN) RAT; and
one or more internal communication lines connecting the cellular processor and the WLAN processor;
wherein the cellular processor and the WLAN processor are configured to couple to a same antenna for communications in the first frequency band;
wherein the cellular processor is configured to notify the WLAN processor via the one or more internal communication lines when the cellular processor is beginning a scan and when the cellular processor is ending a scan in the first frequency band;
wherein the WLAN processor is configured to determine whether to cancel or defer one or more scheduled transmissions during an interval starting at the beginning of the scan and ending at the end of the scan;
wherein, in response to a determination to perform one or more transmissions during the interval, the WLAN processor is configured to notify the cellular processor that the WLAN processor transmitted during the interval; and
wherein, in response to the notification that the WLAN processor transmitted during the interval, the cellular processor is configured to ignore one or more scan measurements taken during an interval in which the WLAN processor transmitted.
