Abstract
A method includes: determining a reference direction for orientation; when a first device rotates around an obstruction, receiving a wireless signal sent by a second device, and obtaining a link quality parameter value according to the received wireless signal; determining a position having greatest shadow fading of the first device according to the obtained link quality parameter value, and using a pointing direction of the position having greatest shadow fading of the first device as a first pointing direction; and determining, according to an included angle θ1 between the reference direction and the first pointing direction and an included angle θ2 between the reference direction and a second pointing direction, a direction in which the second device is located, where the second pointing direction is a pointing direction of the first device.
