Abstract

An angle processing method includes: sending an angle measurement capability request message to a second terminal; receiving a response message carrying angle measurement capability information of the second terminal fed back by the second terminal.

First claim

What is claimed is:

1 . An angle processing method, wherein the angle processing method is performed by a first terminal, and comprises:
transmitting an angle measuring capability request message to a second terminal; receiving a response message from the second terminal, the response message carrying angle measuring capability information of the second terminal, wherein the angle measuring capability information comprises one of the following manners, or a combination of a plurality of the following manners simultaneously: whether serving as a transmitting side for an angle of arrival (AOA) measurement is supported or not; whether serving as a receiving side for an angle of arrival (AOA) measurement is supported or not: whether serving as a transmitting side for an angle of departure (AOD) measurement is supported or not; and whether serving as a receiving side for an angle of departure (AOD) measurement is supported or not; transmitting an angle measuring request message to the second terminal according to the angle measuring capability information of the second terminal, wherein the angle measuring request message comprises: an angle measuring manner for the second terminal indicated by the first terminal, and a subject type corresponding to execution of the second terminal for the angle measuring manner indicated by the first terminal; and receiving an angle measuring response message from the second terminal.

2 . The angle processing method according to claim 1 , wherein the angle measuring capability request message comprises angle measuring capability information of the first terminal.

3 . The angle processing method according to claim 1 , wherein the angle measuring capability request message comprises a request indication field used for indicating the second terminal to transmit the angle measuring capability information.

4 . The angle processing method according to claim 1 , wherein
the angle measuring capability request message and the response message are transmitted by PC5 RRC messages or PC5-S messages.

5 . The angle processing method according to claim 4 , wherein
the angle measuring capability request message is transmitted by UECapabilityEnquirySidelink; and the response message is transmitted by UECapabilityInformationSidelink.

6 . The angle processing method according to claim 1 , wherein
in response to indicating the angle measuring manner for the second terminal is an angle of arrival (AOA) measurement, the indicated subject type corresponding to the execution of the second terminal for the angle measuring manner comprises a transmitting side for the AOA measurement, or a receiving side for the AOA measurement; and in response to indicating the angle measuring manner for the second terminal is an angle of departure (AOD) measurement, the indicated subject type corresponding to the execution of the second terminal for the angle measuring manner comprises a transmitting side for the AOD measurement, or a receiving side for the AOD measurement.

7 . The angle processing method according to claim 1 , wherein the angle measuring response message fed back by the second terminal comprises:
applying the angle measuring manner for the second terminal indicated by the first terminal, and applying the subject type corresponding to the execution of the second terminal for the angle measuring manner and indicated by the first terminal.

8 . The angle processing method according to claim 1 , wherein the angle measuring response message fed back by the second terminal comprises at least one of the following:
rejecting the angle measuring manner for the second terminal indicated by the first terminal, or rejecting the subject type corresponding to the execution of the second terminal for the angle measuring manner and indicated by the first terminal.

9 . The angle processing method according to claim 8 , wherein the angle measuring response message fed back by the second terminal further comprises at least one of the following:
re-indicating the angle measuring manner for the second terminal in a case where the angle measuring response message fed back by the second terminal comprises rejecting the angle measuring manner for the second terminal indicated by the first terminal, or re-indicating the subject type corresponding to the execution of the second terminal for the angle measuring manner in a case where the angle measuring response message fed back by the second terminal comprises rejecting the subject type corresponding to the execution of the second terminal for the angle measuring manner and indicated by the first terminal.

10 . The angle processing method according to claim 1 , wherein the angle measuring response message fed back by the second terminal comprises:
angle measuring request field information for the first terminal, wherein the angle measuring request field information includes: an angle measuring manner for the first terminal indicated by the second terminal, and a subject type corresponding to execution of the first terminal for the angle measuring manner indicated by the second terminal.

11 . The angle processing method according to claim 10 , wherein
in response to indicating the angle measuring manner for the first terminal is an angle of arrival (AOA) measurement, the indicated subject type corresponding to the execution of the first terminal for the angle measuring manner comprises: a transmitting side for the AOA measurement, or a receiving side for the AOA measurement; and in response to indicating the angle measuring manner for the first terminal is an angle of departure (AOD) measurement, the indicated subject type corresponding to the execution of the first terminal for the angle measuring manner comprises: a transmitting side for the AOD measurement, or a receiving side for the AOD measurement.

12 . The angle processing method according to claim 10 , further comprising:
transmitting an angle measuring response message to the second terminal according to the angle measuring request field information for the first terminal.

13 . The angle processing method according to claim 12 , wherein the transmitting the angle measuring response message to the second terminal comprises:
applying the angle measuring manner for the first terminal indicated by the second terminal, and applying the subject type corresponding to the execution of the first terminal for the angle measuring manner and indicated by the second terminal.

14 . The angle processing method according to claim 12 , wherein the transmitting the angle measuring response message to the second terminal comprises at least one of the following:
rejecting the angle measuring manner for the first terminal indicated by the second terminal, or rejecting the subject type corresponding to the execution of the first terminal for the angle measuring manner and indicated by the second terminal.

15 . The angle processing method according to claim 14 , wherein the transmitting the angle measuring response message to the second terminal further comprises at least one of the following:
re-indicating the angle measuring manner for the first terminal in a case where the angle measuring response message fed back by the second terminal comprises rejecting the angle measuring manner for the second terminal indicated by the first terminal, or re-indicating the subject type corresponding to the execution of the first terminal for the angle measuring manner in a case where the angle measuring response message fed back by the second terminal comprises rejecting the subject type corresponding
