SIDELINK POSITIONING REFERENCE SIGNAL PATTERN - A simplified explanation of the abstract

This abstract first appeared for US patent application 17482157 titled 'SIDELINK POSITIONING REFERENCE SIGNAL PATTERN

Simplified Explanation

The patent application describes techniques for wireless communication, specifically for sidelink communication between user equipment (UE).

  • The first UE determines a sidelink positioning reference signal (PRS) pattern for a sidelink position estimation procedure.
  • The sidelink PRS pattern includes at least one PRS transmission occasion for each UE in a group on a shared communication medium.
  • The first UE performs one or more attempts to transmit a first PRS on the PRS transmission occasions associated with it, following the sidelink PRS pattern.
  • The second UE determines the same sidelink PRS pattern and monitors a specific PRS transmission occasion to receive the first PRS from the first UE.

Potential Applications

  • This technology can be applied in wireless communication systems to enable efficient sidelink communication between UEs.
  • It can be used in various scenarios where direct communication between UEs is required, such as vehicle-to-vehicle communication, device-to-device communication, or IoT device communication.

Problems Solved

  • The techniques address the challenge of establishing reliable and efficient communication between UEs in a sidelink scenario.
  • They provide a standardized method for determining and transmitting sidelink PRS patterns, ensuring synchronization and accurate position estimation.

Benefits

  • The techniques improve the reliability and accuracy of sidelink communication by using PRS patterns.
  • They enable efficient use of the shared communication medium by allocating specific PRS transmission occasions to each UE in a group.
  • The standardized approach simplifies the implementation of sidelink communication in wireless systems.


Original Abstract Submitted

Disclosed are techniques for wireless communication. In an aspect, a first UE determine a sidelink positioning reference signal (PRS) pattern for a sidelink position estimation procedure, the sidelink PRS pattern including at least one PRS transmission occasion for each of a group of UEs on a shared communication medium, and performs one or more attempts to transmit a first PRS on one or more PRS transmission occasions associated with the first UE in accordance with the sidelink PRS pattern. In another aspects, a second UE determines the sidelink PRS pattern, and monitors a first PRS transmission occasion for receipt of a first PRS from a first UE in accordance with the sidelink PRS pattern.
