Abstract

A method for sending a positioning signal includes determining, by a first device, a first target access network useable to transmit the positioning signal. The first target access network includes at least a first access network or a second access network. The method further includes sending, by the first device, the positioning signal to a second device by the first target access network.

First claim

determining, by a first device, a first target access network useable to transmit the positioning signal, wherein the first target access network includes at least a first access network or a second access network; and sending, by the first device, the positioning signal to a second device by the first target access network.

2 . The method according to claim 1 , wherein
the first device is a terminal device, the second device is a network device, and the terminal device is configured to maintain a connected state with the first access network and the second access network; or the first device is the network device, the second device is the terminal device, and the terminal device is configured to maintain the connected state with the first access network and the second access network.

3 . The method according to claim 1 , wherein the determining, by the first device, the first target access network useable to transmit the positioning signal comprises:
determining, by the first device, that the first target access network includes the first access network or the second access network in response to the first access network or the second access network satisfying a first condition; and determining, by the first device, that the first target access network includes the first access network and the second access network in response to the first access network and the second access network failing to satisfy the first condition, wherein the first condition includes at least a channel quality of an access network being greater than a first preset value, a load of the access network being less than a second preset value, or a throughput of the access network being less than a third preset value.

4 . The method according to claim 1 , wherein the determining, by the first device, the first target access network useable to transmit the positioning signal comprises:
determining, by the first device, the first target access network based on a pre-configuration setting.

5 . The method according to claim 1 , wherein
the positioning signal comprises a positioning reference signal useable for positioning measurement, and the sending, by the first device, the positioning signal to the second device by the first target access network includes at least:
sending, by the first device, the positioning reference signal to the second device by the first access network, when the first target access network includes at least the first access network, wherein a bandwidth for sending the positioning reference signal is a first bandwidth, and a period for sending the positioning reference signal is a first duration; or
sending, by the first device, the positioning reference signal to the second device by the second access network, when the first target access network includes at least the second access network, wherein the bandwidth for sending the positioning reference signal is a second bandwidth, and the period for sending the positioning reference signal is a second duration.

6 . The method according to claim 1 , wherein the positioning signal includes:
control signaling useable for positioning, or a signal useable for positioning measurement.

7 . A method for receiving a positioning signal, comprising:
receiving, by a second device, the positioning signal from a first device through a first target access network, wherein the first target access network includes at least a first access network or a second access network; and performing, by the second device, processing on the positioning signal.

8 . The method according to claim 7 , wherein
the first device is a terminal device, the second device is a network device, and the terminal device is configured to maintain a connected state with the first access network and the second access network; or the first device is the network device, the second device is the terminal device, and the terminal device is configured to maintain the connected state with the first access network and the second access network.

9 . The method according to claim 7 , wherein
the first target access network includes the first access network or the second access network in response to the first access network or the second access network satisfying a first condition; and the first target access network includes the first access network and the second access network in response to the first access network and the second access network failing to satisfy the first condition; wherein the first condition includes at least a channel quality of an access network being greater than a first preset value, a load of the access network being less than a second preset value, or a throughput of the access network being less than a third preset value.

10 . The method according to claim 7 , wherein the first target access network is determined based on a pre-configuration setting.

11 . The method according to claim 7 , wherein the positioning signal includes:
control signaling useable for positioning, or a signal useable for positioning measurement.

12 . The method according to claim 7 , wherein
