A method and apparatus operate a device on a licensed spectrum and an unlicensed spectrum. The device can operate on a Wireless Wide Area Network (WWAN) channel using a WWAN transceiver via a WWAN Radio Access Technology (RAT) base station using a WWAN RAT. The device can communicate with a WWAN RAT Wireless Local Area Network (WLAN) base station using the WWAN RAT via a WWAN RAT WLAN receiver on a WWAN RAT WLAN channel operating on a WLAN frequency. A personal access point WLAN channel of a WLAN frequency-based personal access point can be selected that provides the least desense of the WWAN RAT WLAN channel on the WWAN RAT WLAN receiver.

Method and apparatus for operating a device on a licensed spectrum and an unlicensed spectrum

A method and apparatus operate a device on a licensed spectrum and an unlicensed spectrum. The device can operate on a Wireless Wide Area Network (WWAN) band via a WWAN base station using a WWAN Radio Access Technology (RAT). The device can connect to a Wireless Local Area Network (WLAN) base station using the WWAN RAT on a WWAN RAT WLAN band operating on a WLAN frequency and can connect to a WLAN access point using a WLAN RAT on a WLAN RAT band operating on a WLAN frequency. The WWAN RAT WLAN band can be determined to be the same band as the WLAN RAT band. A signal metric of the WWAN RAT WLAN band or the WLAN RAT band can be compared to a threshold. Whether to disable communications on the WWAN RAT WLAN band or the WLAN RAT band can be determined based on comparing the signal metric of the WWAN RAT WLAN band or the WLAN RAT band to a threshold. Communications of the WWAN RAT WLAN band or the WLAN RAT band can be disabled if the communications on the WWAN RAT WLAN band or the WLAN RAT band should be disabled.

A method and apparatus operate a device on a licensed spectrum and an unlicensed spectrum. The device can operate on a Wireless Wide Area Network (WWAN) channel using a WWAN base station using a WWAN Radio Access Technology (RAT). At least one Wireless Local Area Network (WLAN) base station that uses the WWAN RAT operating on a WLAN frequency can be detected. WLAN frequencies can be scanned. Information including information about the at least one WLAN base station using the WWAN RAT, the results of scanning the WLAN frequencies, and device specific information to a base station can be sent. A WLAN channel of the WLAN frequencies with a WLAN base station of the at least one WLAN base station using the WWAN RAT can be communicated on in response to sending the information.

A method on an electronic device for a wireless network is described. A wireless signal is received from a second electronic device. A receive power level indication for the received wireless signal is determined. A path-loss offset for the received wireless signal is determined based on sensor data that indicates a path-loss condition. A path-loss for the received wireless signal is estimated based on the receive power level indication and the path-loss offset. A function is performed based on the path-loss and the path-loss threshold.

Methods and devices for path-loss estimation

A method and apparatus operate a device on a licensed spectrum and an unlicensed spectrum. The device can operate on a Wireless Wide Area Network (WWAN) channel using a WWAN transceiver via a WWAN Radio Access Technology (RAT) base station using a WWAN RAT. The device can communicate with a WWAN RAT Wireless Local Area Network (WLAN) base station using the WWAN RAT via a WWAN RAT WLAN receiver on a WWAN RAT WLAN channel operating on a WLAN frequency. Activation of WLAN frequency-based personal access point using a WLAN personal access point transceiver on the device can be detected. A personal access point WLAN channel of the WLAN frequency-based personal access point can be selected that provides the least desense of the WWAN RAT WLAN channel on the WWAN RAT WLAN receiver.

A WLAN access point load on the WWAN RAT WLAN channel can be calculated based on scanning the WLAN frequencies, where a WLAN access point uses a WLAN RAT. The device can disable communication using the WWAN RAT WLAN channel when the WLAN access point load exceeds a threshold and allow communication on the WWAN channel when the WLAN access point load exceeds a threshold.

Some battery-powered devices, such as smartphones, can be unlocked with use of wearable NFC (Near Field Communication) authentication devices. However, using conventional NFC authentication procedures is expensive in terms of power consumption because of continual rediscovery and reauthentication of the wearable authentication device. To address this, the present inventors, devised, among other things, more efficient methods for authenticating NFC-tagged authentication device, such as rings. For example, one embodiment uses two NFC polling loops or structures, instead of one as conventionally done. The first loop, used for initial authentication, entails scanning for two or more types of NFC tags. And the second loop, invoked after initial authentication, scans for a smaller subset of the two or more types to conserve battery power.

The present invention provides a multiple coil structure for supporting multiple types of charging and near field communications. The multiple coil structure includes an inner charging coil comprising a first conductor path forming one or more loops, wherein the direction of travel of the conductor path from an end point of the first conductor path is one of a substantially clockwise direction or a substantially counter-clockwise direction, and wherein the inner charging coil has an inner boundary and an outer boundary. The multiple coil structure further includes an outer charging coil comprising a second conductor path forming one or more loops, which extend around the outer boundary of the inner charging coil, wherein the direction of travel of the conductor path from an end point of the second conductor path is one of a substantially clockwise direction or a substantially counter-clockwise direction, and wherein the outer charging coil has an inner boundary and an outer boundary. The multiple coil structure still further includes a near field communication coil comprising a third conductor path forming one or more loops within the inner boundary of the inner charging coil, wherein the direction of travel of the conductor path from an end point of the third conductor path is one of a substantially clockwise direction or a substantially counter-clockwise direction.

A processormay decide to execute a full device scan based in part on the protocol-specific channel criterion.

System and method for mitigating the effects of interferers while performing conditional device scan

A near field communication (NFC) system includes a portable device having an embedded NFC antenna, an add-on module blocking the embedded NFC coil and an NFC transfer coil wrapped around the add-on module to eliminate blocking of the embedded NFC antenna. A predetermined set of NFC antenna tuning parameters is associated with each add-on module and is applied by the device's NFC controller upon identifying the docked add-on module. In an embodiment, the NFC transfer coil includes linked first and second NFC coils which replicate NFC signals in each other. The NFC transfer coil may include a ferrite shield between each of the linked NFC coils and the add-on module to minimize the creation of eddy currents that may degrade the performance of the embedded NFC antenna.
