Abstract
A method includes: receiving, by a first RRU, a first reference signal sent by a second RRU, where the first RRU is a to-be-positioned RRU, and the second RRU is an RRU at a known location; determining, by the first RRU, a first delay value based on the first reference signal; and reporting, by the first RRU, the first delay value to an upper-layer network element, so that the upper-layer network element performs location resolving processing based on the first delay value, to obtain location.
