Patent ID: 10462805

Abstract:
A wireless communication device (UE) includes 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. In some embodiments, the apparatus includes a wireless local area network (WLAN) processor configured to conduct wireless communications according to a second RAT in the first frequency band. In some embodiments, the cellular processor and the WLAN processor are configured to couple to a common antenna for communications in the first frequency band. In some embodiments, the cellular processor may notify the WLAN processor when it is scanning and/or when it is assigned secondary component carriers in the first frequency band. In some embodiments, the WLAN processor may notify the cellular processor when it is transmitting. In some embodiments, the WLAN processor and/or the cellular processor may perform one or more actions in response to such notifications to improve coexistence in the first frequency band.
