Abstract
A method of wireless communication performed by a user equipment (UE) is disclosed and includes determining a position of the UE based on a first positioning synchronization source; pre-configuring a first sidelink coordination group for use by the UE prior to an occurrence of one or more first triggering events, wherein the first sidelink coordination group uses a second positioning synchronization source that is different than the first positioning synchronization source; and in response to a determination that the one or more first triggering events has occurred, transitioning to use of the first sidelink coordination group for determining the position of the UE.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- determining a position of the UE based on a first positioning synchronization source;
- pre-configuring a first sidelink coordination group for use by the UE prior to an occurrence of one or more first triggering events, wherein the first sidelink coordination group uses a second positioning synchronization source that is different than the first positioning synchronization source;
- and
- in response to a determination that the one or more first triggering events has occurred, transitioning to use of the first sidelink coordination group for determining the position of the UE.
A method of wireless communication performed by a location server, comprising:
- receiving, from a user equipment (UE), an indication of one or more preferred sidelink devices with which the UE can communicate;
- and
- sending, to the UE, an indication of one or more sidelink coordination groups for positioning pre-configuration by the UE, wherein the one or more sidelink coordination groups include at least one of the one or more preferred sidelink devices.
A user equipment (UE), comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
- determine a position of the UE based on a first positioning synchronization source;
- pre-configure a first sidelink coordination group for use by the UE prior to an occurrence of one or more first triggering events, wherein the first sidelink coordination group uses a second positioning synchronization source that is different than the first positioning synchronization source;
- and
- in response to a determination that the one or more first triggering events has occurred, transition to use of the first sidelink coordination group for determining the position of the UE.
A location server, comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
- receive, via the at least one transceiver, from a user equipment (UE), an indication of one or more preferred sidelink devices with which the UE can communicate;
- and
- send, via the at least one transceiver, to the UE, an indication of one or more sidelink coordination groups for positioning pre-configuration by the UE, wherein the one or more sidelink coordination groups include at least one of the one or more preferred sidelink devices.
