Abstract

To more accurately determine whether a first electronic device is disposed in a second electronic device, which may be an enclosure for the first electronic device, the first electronic device may determine Voltage Standing Wave Ratio (VSWR) values at its transceiver, and determine whether it is moving and/or disposed in the second electronic device based on the VSWR values. If the first electronic device determines that it is disposed in the second electronic device, then the first electronic device may perform radio frequency coexistence actions, such as backing off (e.g., reducing) radio power or deactivating its radio to avoid radio frequency coexistence issues with the second electronic device.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. application Ser. No. 18/075,116, filed Dec. 5, 2022, entitled “SYSTEMS AND METHODS FOR MANAGING RF COEXISTENCE BETWEEN ACCESSORIES,” which claims priority to U.S. Provisional Application No. 63/404,055, filed Sep. 6, 2022, entitled “SYSTEMS AND METHODS FOR MANAGING RF COEXISTENCE BETWEEN ACCESSORIES,” each of which is incorporated by reference in its entirety for all purposes. BACKGROUND The present disclosure relates generally to wireless communication, and more specifically to coexistence between radios of accessory devices. When multiple radios of multiple electronic (e.g., accessory) devices operate concurrently and/or in proximity in one another, emissions by the radios may aggregate to exceed emission regulations, cause receiver saturation or desense of the radios, or cause other issues that may negatively impact user experience.

In another embodiment, an electronic device includes one or more antennas, a transceiver coupled to the one or more antennas, and processing circuitry coupled to the transceiver. The processing circuitry is configured to receive an indication that the electronic device is not in use, receive a Voltage Standing Wave Ratio (VSWR) value for the one or more antennas, and perform a radio frequency coexistence action based on the VSWR value. In yet another embodiment, one or more non-transitory, tangible, computer-readable media stores instructions that cause processing circuitry of a first electronic device to receive, via a transceiver of the first electronic device, an indication of a status of a second electronic device; receive a Voltage Standing Wave Ratio (VSWR) value for one or more antennas of the first electronic device coupled to the transceiver based on the status; and perform a radio frequency coexistence action based on the VSWR value.
