Abstract

The present disclosure describes methods, terminals, and base stations for terminal positioning method. One example method applied to a baseband unit (BBU) in an indoor distributed NodeB system includes: receiving an uplink positioning signal forwarded by multiple remote radio units RRUs, where the uplink positioning signal is sent by a to-be-positioned terminal to the multiple RRUs; selecting, from the multiple RRUs, at least two RRUs as target RRUs according to the uplink positioning signal and a preset rule; and respectively obtaining signal angles of arrival corresponding to the target RRUs, and determining a location of the to-be-positioned terminal according to the signal angles of arrival, locations of the target RRUs, and a preset algorithm.
