Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a plurality of UEs for a UE positioning session. The UE may identify a set of parameters for the UE positioning session. The UE may broadcast information indicating at least the set of parameters for the UE positioning session. The UE may receive, from at least one of the plurality of UEs, a set of positioning reference signals (PRSs) based at least in part on the set of parameters. The UE may broadcast, based at least in part on the set of PRSs, positioning information. Numerous other aspects are provided.
Claims25
A first user equipment (UE) for wireless communication, comprising:
- a memory;
- one or more processors, coupled to the memory, configured to:
- identify a plurality of UEs for a UE positioning session;
- identify a set of parameters for the UE positioning session;
- and
- a transceiver configured to:
- broadcast information indicating at least the set of parameters for the UE positioning session;
- receive, from at least one of the plurality of UEs, a set of positioning reference signals (PRSs) based at least in part on the set of parameters, wherein receiving the set of PRSs includes receiving a plurality of PRSs from a particular UE of the plurality of UEs;
- and
- broadcast, based at least in part on the set of PRSs, positioning information, wherein the transceiver is further configured to:
- receive, from the particular UE, second positioning information based at least in part on a PRS transmitted by the first UE, wherein the second positioning information is received (a) between reception of a first PRS and a second PRS of the plurality of PRSs, or (b) after all PRSs of the plurality of PRSs have been transmitted.
A first user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory;
- and
- a transceiver, configured to:
- receive, from a second UE, broadcasted information indicating a set of parameters for a UE positioning session;
- broadcast a first set of positioning reference signals (PRSs) based at least in part on the set of parameters, wherein broadcast of the first set of PRSs includes broadcast of a plurality of PRSs;
- receive a second set of PRSs based at least in part on the set of parameters;
- and
- broadcast positioning information, based at least in part on at least one of the first set of PRSs or the second set of PRSs, wherein the transceiver is further configured to:
- receive, from the second UE, second positioning information based at least in part on the plurality of PRSs, wherein the second positioning information is received between broadcasting of a first PRS and a second PRS of the plurality of PRSs.
A method of wireless communication performed by a first user equipment (UE), comprising:
- receiving a plurality of messages from a plurality of UEs;
- identifying a plurality of UEs for a UE positioning session based on the received plurality of messages;
- identifying a set of parameters for the UE positioning session in response to identifying the plurality of UEs for the positioning session;
- broadcasting information indicating at least the set of parameters for the UE positioning session;
- receiving, from at least one of the plurality of UEs, a set of positioning reference signals (PRSs) based at least in part on the set of parameters;
- and
- broadcasting, based at least in part on the set of PRSs, positioning information, wherein the first UE is configured to enable other UEs of the plurality of UEs to transmit multiple PRSs in association with a single pre-PRS stage, a single post-PRS stage, or a combination thereof.
A method of wireless communication performed by a first user equipment (UE), comprising:
- receiving, from a second UE, broadcasted information indicating a set of parameters for a UE positioning session;
- broadcasting a first set of positioning reference signals (PRSs) based at least in part on the set of parameters, wherein broadcasting the first set of PRSs includes broadcasting a plurality of PRSs;
- receiving a second set of PRSs based at least in part on the set of parameters;
- broadcasting positioning information, based at least in part on at least one of the first set of PRSs or the second set of PRSs;
- and
- receiving, from the second UE, second positioning information based at least in part on the plurality of PRSs, wherein the second positioning information is received between broadcasting of a first PRS and a second PRS of the plurality of PRSs.
