Abstract: A method, including: sending first information and second information to each of a plurality of second network devices, where the first information indicates the second network device to determine a first delay of a pilot signal passing through a transmit channel and a receive channel of the second network device, and the second information indicates the second network device to send the pilot signal to one or more third network devices, and receive the pilot signal from the one or more third network devices; receiving the first delay of each second network device and one or more second delays; determining location information of each second network device based on an air interface delay between second network devices, where the air interface delay between the second network devices is determined based on the first delay of each second network device and the one or more second delays.

Abstract: A positioning method, a device, a system, a chip, and a storage medium are provided. A network device is externally connected to N antennas, the network device has N receive channels, and the N antennas are in a one-to-one correspondence with the N receive channels. The method includes: A network device receives, by using each of the N antennas, a positioning signal sent by a terminal device, determines TOA information and/or RSSI information of the positioning signal on each of the N receive channels, and sends the TOA information and/or the RSSI information of the positioning signal on each of the N receive channels to a service anchor. The service anchor is configured to position the terminal device based on the TOA information and/or the RSSI information.
