Abstract: An apparatus such as a wireless communication device (UE) may include first circuitry configured to conduct wireless communications according to a first radio access technology (RAT) in a first frequency band and in a second frequency band, where 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. The apparatus may include second circuitry 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. The apparatus may be configured to determine to perform a scan operation in the first frequency band using the first circuitry and, based on one or more transmissions by the second circuitry using the first frequency band, adjust one or more parameters for the scan measurement by the first circuitry. The cellular communications in the first frequency band may be LAA communications, for example.

Abstract: A client device and a host device may create a local connection for providing wide area network access, such as Internet access, to the client device. In some embodiments, the client device may have limited network capabilities and may not be able to access the Internet without the host device. The client device may provide its speed and direction in a message to potential host devices. A host device may calculate a suitability metric, based on the speed and direction of the client as well as connection properties of the networks, which indicates an ability for the host device to connect the client device to the Internet. The host device may provide the suitability metric within a connection request to the client device. Based on the suitability metric and/or other factors, the client device and the host device may establish the local connection.

Abstract: This disclosure relates to performing antenna selection to reduce interference in a wireless device. According to some embodiments, it may be determined whether simultaneous communication according to first and second wireless communication technologies causes performance degradation to a third wireless communication technology. If the simultaneous communication according to first and second wireless communication technologies does cause performance degradation to the third wireless communication technology, selection of antenna(s) used for the communications may be based at least in part on the determination that the simultaneous communication according to the first and second wireless communication technologies causes performance degradation to the third wireless communication technology.
