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.

Claim (Index 2):
The method according to  claim 1 , wherein the method further comprises:\n prior to the selecting, from the multiple RRUs, at least two RRUs as target RRUs according to the uplink positioning signal and the preset rule, obtaining a physical distance between every two of the at least two RRUs; and wherein the selecting, from the multiple RRUs, at least two RRUs as target RRUs according to the uplink positioning signal and the preset rule comprises:\n separately obtaining, according to the uplink positioning signal, a signal strength of the uplink positioning signal received by each of the multiple RRUs; and \n selecting the at least two RRUs as the target RRUs in response to determining the physical distance between every two of the at least two RRUs is greater than a first preset value and a signal strength of the uplink positioning signal received by each of the at least two RRUs is greater than a second preset value.
