Abstract
A vehicle-enabled user equipment (VUE) and related techniques are disclosed. In one aspect, the VUE issues a periodic broadcast, or signals a response to a requesting source, identifying its location management capability (LMC). The UE forms a link with a recipient VUE of the broadcast to perform joint localization of the pedestrian UE (PUE). Joint localization by VUE and another VUE may be performed by VUEs and PUEs in the region exchanging ranging signals and ego measurements. The VUE determines a location jointly of the PUE. The location can be determined upon a request, periodically, or in response to a triggered event.
Claims30
A method of a vehicle user equipment (VUE), comprising:
- signaling a pedestrian user equipment (PUE) that the VUE has location management capability (LMC);
- exchanging location information with the PUE;
- and
- determining, jointly with a second LMC-based VUE using the location information, a location of the PUE.
A vehicle user equipment (VUE), comprising:
- a processor configured to:
- signal a pedestrian user equipment (PUE) that the VUE has location management capability (LMC),
- exchange location information with the PUE, and
- determine, jointly with a second LMC-based VUE using the location information, a location of the PUE.
A non-transitory computer-readable medium storing computer-executable code for a vehicle-enabled user equipment (VUE), the code when executed by a processor causes the processor to:
- signal a PUE that the VUE has location management capability (LMC);
- exchange location information with the PUE;
- and
- determine, jointly with a second LMC-based VUE using the location information, a location of the PUE.
A vehicle-enabled user equipment (VUE), comprising:
- means for signaling a pedestrian user equipment (PUE) that the VUE has location management capability (LMC);
- means for exchanging location information with the PUE;
- and
- means for determining, jointly with a second LMC-based VUE using the location information, a location of the PUE.
