SYSTEMS AND METHODS FOR MODES OF SIDELINK POSITIONING OF MOBILE DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18366455 titled 'SYSTEMS AND METHODS FOR MODES OF SIDELINK POSITIONING OF MOBILE DEVICES

Simplified Explanation

The patent application describes a method for performing sidelink positioning of multiple User Equipments (UEs) using a Sidelink Positioning Protocol (SLPP) in session mode or sessionless mode.

  • Sidelink positioning of UEs can be done using SLPP in session mode or sessionless mode.
  • In session mode, one UE discovers other UEs, establishes a session for SLPP, exchanges SLPP messages, and enables sidelink positioning.
  • In sessionless mode, a UE may not discover all UEs but can still exchange SLPP messages for positioning.
  • The technology can be applied to SL positioning using SL PRS signals, WiFi, UWB, and GNSS signals.
      1. Potential Applications
  • Vehicle-to-vehicle communication for autonomous driving
  • Indoor positioning for asset tracking
  • Emergency response coordination in disaster scenarios
      1. Problems Solved
  • Efficiently positioning multiple UEs in proximity to each other
  • Facilitating communication and coordination without relying on centralized infrastructure
      1. Benefits
  • Improved accuracy in positioning multiple UEs
  • Enhanced reliability of communication in dynamic environments
  • Flexibility to operate in session or sessionless modes based on requirements


Original Abstract Submitted

Sidelink positioning of a plurality of UEs may be performed using a sidelink (SL) positioning protocol (SLPP) in either a session mode or a sessionless mode. In the session mode, one UE in the plurality of UEs may discover the other UEs, determine a session for SLPP, indicate the session to the other UEs, and exchange a plurality of SLPP messages with the other UEs, where the SLPP messages are part of the session and enable the sidelink positioning. In the sessionless mode, a UE may not discover some or all other UEs in the plurality of UEs and may exchange a plurality of SLPP messages with the other UEs, where the SLPP messages are not part of a session but enable the sidelink positioning. The two modes may each apply to SL positioning using SL PRS signals as well as WiFi, UWB and GNSS signals.
