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.
Claims35
A method of wireless communication performed by a vehicle-enabled user equipment (VUE), comprising:
- issuing a broadcast identifying a location management capability of the VUE;
- forming first bi-directional link with a pedestrian UE (PUE) in receipt of the broadcast;
- forming second link with a recipient VUE of the broadcast to localize the PUE using the first bi-directional link and the second link;
- and
- localizing the PUE in response to a determination of a position of the PUE based on location information from the recipient VUE and the PUE.
A vehicle-enabled user equipment (VUE), comprising:
- a memory;
- and
- at least one processor configured to execute processor-executable instructions stored on the memory to cause the VUE to:
- issue a broadcast identifying a location management capability of the VUE form a first bi-directional link with a pedestrian UE (PUE) in receipt of the broadcast;
- form a second link with a recipient VUE of the broadcast for localizing a the PUE using the first bi-directional link and the second link;
- and
- localize the PUE in response to a determination of a position of the PUE based on location information from the recipient VUE and the PUE.
A vehicle-enabled user equipment (VUE), comprising:
- means for issuing a broadcast identifying a location management capability of the VUE;
- and
- means for forming a first bi-directional link with a pedestrian UE (PUE) in receipt of the broadcast,
- wherein the means for forming is further configured to form a second link with a recipient VUE of the broadcast to localize the PUE using the first bi-directional link and the second link;
- and
- wherein the means for forming the second link to localize the PUE is further is in response to a determination of a position of the PUE based on location information from the recipient VUE and the PUE.
A non-transitory computer-readable medium storing computer-executable code fora vehicle-enabled user equipment (VUE), the code when executed by a processor causes the processor to:
- issue a broadcast identifying a location management capability of the VUE;
- form a first bi-directional link with a pedestrian UE (PUE) in receipt of the broadcast;
- form a second link with a recipient VUE of the broadcast to localize the PUE using the first bi-directional link and the second link;
- and
- wherein the code executed by the processor to form the second link to localize the PUE further causes the processor to localize the PUE in response to a determination of a position of the PUE based on location information from the recipient VUE and the PUE.
