5 LAA/Wi-Fi LAA/WI-FI COEXISTENCE FOR 5GHZ ANTENNA SHARING

摘要

A wireless communication device (UE) includes a cellular processor configured to perform wireless communications according to a first radio access technology (RAT) in a first frequency band and in a second frequency band, the first RAT being a cellular RAT, and a first The frequency band is in the unlicensed spectrum and the second frequency band is in the licensed spectrum. In some embodiments, the apparatus includes a wireless local area network (WLAN) processor configured to perform wireless communications according to a second RAT in a 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 cellular processor may perform one or more actions in response to such notifications to improve coexistence in the first frequency band.
