Techniques are described for interference reductions using, e.g., a Received Signal Strength Indicator (RSSI) or packet error rate threshold. User Equipment that implements these techniques may reduce interference among personal area network enabled devices, for example, with the added benefit of reducing power consumption by reduced radio frequency transmissions. By reducing interference, the performance of personal area network devices may be improved.

Interference reduction using signal quality

Techniques are described for interference reduction using, e.g., a Received Signal Strength Indicator (RSSI) or packet error rate threshold. UEs that implement these techniques may reduce interference among personal area network enabled devices, for example, with the added benefit of reducing power consumption by reduced RF transmissions. By reducing interference, the performance of personal area network devices may be improved.

A monitoring device may monitor its proximity to a monitored station. The monitored station may transmit a proximity indicator to the monitoring device. For example, the proximity indicator may include the received signal strength of a signal sent by the monitored station. Wireless interface control circuitry at the monitoring device may monitor the status of the proximity indicator for changes. If one or more criteria set by an application processor are met by a detected change, the wireless interface control circuitry may send a status update to the application processor. In the criteria are not met, generation of the status update may be forgone. The application processor need not monitor the proximity indicator status and may remain in a reduced power consumption mode for longer periods.

Proximity alert using signal strength

A power transmitting device includes a processor circuit. The processor circuit receives messages, such as advertising messages and/or scan response messages, from power receiving devices. The messages include device specific data that pertains to the corresponding power receiving devices that transmitted the messages. The device specific data includes, for example, data pertaining to the hardware, firmware, charging state, and/or device state of the corresponding power receiving device. The processor circuit selects one of the power receiving devices based in part on the device specific data contained in the messages. The processor circuit initiates a wireless power transfer connection to the selected one of the power receiving devices.

Communicating device data prior to establishing wireless power connection

A wireless communication device includes a wireless charging circuit configurable to receive a wireless power signal from a power transmitting unit and to charge the wireless communication device under control of a processing device and in conjunction with a charging session with the power transmitting unit. A wireless interface device operates under control of the processing device to establish a wireless connection with the power transmitting unit via a connection establishment procedure, wherein the wireless connection is separate from the wireless power signal. Control data is exchanged with the power transmitting unit via the wireless connection, wherein the control data is used by the processing device to implement the charging session with the wireless charging circuit. A response is generated to a disruption event of the wireless communication device that includes implementing a restoration procedure for restoring the wireless connection, without implementing the connection establishment procedure.

Wireless communication device with connection restoration and methods for use therewith

A first wireless node may determine that a first reserved retransmission frame overlaps with a second reserved transmission frame and a second reserved retransmission frame and that the second reserved transmission frame overlaps with a first reserved transmission frame and the first reserved retransmission frame. The first reserved transmission frame and the first reserved retransmission frame may be reserved for wireless communication with a first master node, and the second reserved transmission frame and the second reserved retransmission frame are reserved for wireless communication with a second master node. The wireless node may also process and acknowledge data received from the first master node during the first reserved transmission frame based on the determining, ignore data sent by the second master node during the second reserved transmission frame based on the determining, and process and acknowledge data received from the second master node during the second reserved retransmission frame.

Communicating with multiple devices

A device implements multiple protocols that share overlapping resources. In some cases, a first operation, such as a scan, may have a resource conflict with a second operation associated with a different protocol. In some cases, determining grant normal priority level requests associated with the first operation over those at the normal priority level associated with the second operation may lead to operator-noticeable degradation in device performance. A protocol controller may request a selected portion of the first operation at a low priority level. Requesting the selected portion at the low priority level may allow the second operation to selectively override the portion of the first operation. The selective overriding of the first operation may allow for execution of the first and second operations without operator-noticeable performance degradation.

Resource sharing priority

Communicating with two nodes with overlapping frames

According to an example embodiment, a wireless node may determine that a first reserved retransmission frame overlaps with a second reserved transmission frame and a second reserved retransmission frame and that the second reserved transmission frame overlaps with a first reserved transmission frame and the first reserved retransmission frame. The first reserved transmission frame and the first reserved retransmission frame may be reserved for wireless communication with a first master node, and the second reserved transmission frame and the second reserved retransmission frame are reserved for wireless communication with a second master node. The wireless node may also process and acknowledge data received from the first master node during the first reserved transmission frame based on the determining, ignore data sent by the second master node during the second reserved transmission frame based on the determining, and process and acknowledge data received from the second master node during the second reserved retransmission frame based on the determining.
