1. A method performed by a first electronic device, the method comprising:
- receiving first sensor data from at least one of the first electronic device or a second electronic device that indicates a first path-loss condition that affects receive power level indications;
selecting a context update interval based on the first sensor data;
responsive to an elapsed time after the selection meeting the context update interval, receiving second sensor data from at least one of the first or second electronic device that indicates a second path-loss condition that affects receive power level indications;
receiving a wireless signal from the second electronic device;
determining a receive power level indication for the received wireless signal;
calculating an initial path-loss based on the receive power level indication;
determining a path-loss offset for the initial path-loss based on the second sensor data;
calculating a second path-loss for the received wireless signal by adding the path-loss offset to the initial path-loss; and
responsive to the second path-loss meeting a path-loss threshold value, performing a function.

Abstract
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.

16. A system comprising:
-
one or more radio transceivers; one or more processors; and one or more non-transitory memory devices containing instructions that when executed by the one or more processors cause the system to perform operations comprising; receive first sensor data from at least one of the system or a remote electronic device that indicates a first path-loss condition that affects receive power level indications; selecting a context update interval based on the first sensor data; responsive to an elapsed time after the selection meeting the context update interval, receiving second sensor data from at least one of the system or the remote electronic device that indicates a second path-loss condition that affects receive power level indication; receiving, via the one or more radio transceivers, a wireless signal from the remote electronic device; determining a receive power level indication for the received wireless signal; calculating an initial path-loss based on the receive power level indication; determining a path-loss offset for the initial path-loss based on the second sensor data; calculating a second path-loss for the received wireless signal by adding the path-loss offset to the initial path-loss; and responsive to the second path-loss meeting a path-loss threshold value, performing a function. - View Dependent Claims (17, 18, 19, 20)
