Abstract
Methods for sidelink-Aided multi-Round Trip Time Positioning (RTT) in the absence of a serving gNB in a wireless communication system is characterized by, that single-sided or double-side multi-round trip time (RTT)—of wireless communication signals—based positioning involving the sidelink (SL) in the wireless communication system is proceeded by using an initiator node and the position of a target user equipment (UE) is computed.

A method for Sidelink-Aided multi-Round Trip Time Positioning (RTT) without serving gNB involvement in a wireless communication system, characterized by, that single-sided or double-side multi-round trip time (RTT)—of wireless communication signals—based positioning involving a sidelink (SL) in the wireless communication system is proceeded by using an initiator node, and a position of a target user equipment UE is computed.
An initiator node which is responsible for identifying one or more anchor UE(s) to be involved in multi round-trip-time positioning and forwarding any resource allocation for positioning to a plurality of nodes.
A target UE comprises a processor coupled with a non-transitory memory in which computer program instructions are stored, said instructions being configured to perform operations comprising:
- Send initiation to known anchor UE(s) including request for identification of additional anchor UE(s) (if required);
- Received response from known anchor UE(s)?;
- Send forward request for initiation to (chosen subset of) known anchor UE(s) (if required);
- Proceed with multi-RTT/Retry/Terminate?;
- Send SL resource allocation for multi-RTT to anchor UE(s);
- Perform one-sided or two-sided multi-RTT-related SL-PRS transmissions and measurements;
- Received measurements?;
- and
- Compute position.
One or more anchor UE(s) initially known to a target UE, each of the one or more anchor UE (s) comprising a respective processor coupled with a respective memory in which respective computer program instructions are stored, said instructions being configured to perform operations comprising:
- Received request for multi-RTT from target UE?;
- Send response to target UE (including info on other anchor UE(s) if requested by target UE);
- Received forward request from target UE?;
- Forward initiation for multi-RTT to anchor UE(s) indicated in forward request;
- Received response from other anchor UE(s)?;
- Forward response by other anchor UE(s) to target UE;
- Received resource allocation from target UE?;
- Perform one-sided or two-sided multi-RTT-related SL-PRS transmissions and measurements;
- and
- Send measurements to target UE.
One or more anchor UE(s) initially unknown to a target UE, each of the one or more anchor US(s) comprising a respective processor coupled with a respective memory in which respective computer program instructions are stored, said instructions being configured to perform operations comprising:
- Received forwarded request for multi-RTT from anchor UE?;
- Send response to anchor UE which forwarded request;
- Received resource allocation from target UE?;
- Perform one-sided or two-sided multi-RTT-related SL-PRS transmissions and measurements;
- and
- Send measurements to target UE.
