摘要： 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.

摘要： A user equipment (UE) device may be configured to effectively manage coexistence of multiple radio access technologies (RATs) on the device. Respective controllers responsible for at least partially managing wireless communications according to corresponding respective RATs may communicate to each other expected data transfer patterns that take place over their respective communications links, including application-specific data transfer patterns and data-transfer-mechanism-specific data transfer patterns. The RAT controllers may manage their respective data transfers according to the expected data-transfer pattern information associated with the other RATs received from each in order to prevent data transmission by the device over one RAT link interfering with data transmission of the device over another RAT link. The expected data pattern information may be sent in messaging of a specific type with indexes determined based at least on a status of the data transfer mechanism and a connectivity status of the UE device.

摘要： A method for facilitating in-device coexistence between wireless communication technologies on a wireless communication device is provided. The method can include transmitting data traffic from the wireless communication device via an aggressor wireless communication technology; determining occurrence of an in-device interference condition resulting from transmission of the data traffic via the aggressor wireless communication technology interfering with concurrent data reception by the wireless communication device via a victim wireless communication technology; and reducing a bit rate of the data traffic transmitted via the aggressor wireless communication technology in response to the in-device interference condition.

摘要： An apparatus, system, and method for performing handover of a mobile station (MS) between a base station (BS) and an access point (AP) are described. In one embodiment, the MS may receive one or more threshold values for reporting measurements to the BS. The MS may convert the threshold values to device-specific threshold values. The MS may determine one or more network quality values associated with the AP. The MS may compare the network quality values to the device-specific threshold values. In response to the network quality values exceeding the device-specific threshold values, the MS may convert the network quality values to calibrated network quality values. The MS may provide the calibrated network quality values. The MS may perform handover from the BS to the AP based on providing the calibrated network quality values to the BS.

摘要： A single chip mobile wireless device capable of receiving and transmitting over one wireless network at a time maintains registration on two wireless communication networks that each use different communication protocols in parallel. Periodically, the mobile wireless device tunes one or more receivers from a first wireless network to a second wireless network in order to listen for paging messages addressed to the mobile wireless device from the second wireless network. The first wireless network suspends allocation of radio resources to the mobile wireless device based on receipt of a suspension message from the mobile wireless device, or based on knowledge of a paging cycle for mobile wireless device in the second wireless network, or based on detection of an out of synchronization condition with the mobile wireless device.

摘要： 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.
