MULTI-ANCHOR SIDELINK QUASI-COLOCATION INDICATION AND CONFIGURATION FOR ENHANCED POSITIONING AND SENSING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17806723 titled 'MULTI-ANCHOR SIDELINK QUASI-COLOCATION INDICATION AND CONFIGURATION FOR ENHANCED POSITIONING AND SENSING

Simplified Explanation

The patent application describes a system where a base device determines the relationship between two wireless reference signals transmitted by separate user equipment (UE) devices. These reference signals are used for positioning or radio frequency sensing.

  • The system involves a base device and two separate UE devices acting as sidelink (SL) anchors.
  • The base device determines the relationship between the wireless reference signals transmitted by the two SL anchors.
  • The base device then sends this information, called mSL-QCL, to the receiving UE device.
  • The mSL-QCL information indicates the relationship between the two reference signals.

Potential Applications

  • This technology can be used for accurate positioning of a receiving UE device.
  • It can also be used for radio frequency sensing, which can help in detecting and analyzing wireless signals in the environment.

Problems Solved

  • The technology solves the problem of accurately determining the relationship between wireless reference signals transmitted by separate UE devices.
  • It provides a way to share this information with the receiving UE device.

Benefits

  • Accurate positioning of a receiving UE device can be achieved using the mSL-QCL information.
  • Radio frequency sensing can be performed more effectively with the knowledge of the QCL relation between reference signals.
  • The technology enables better coordination and communication between different UE devices and the base device.


Original Abstract Submitted

In some implementations, a base device may determine a quali-colocation (QCL) relation between a first wireless reference signal transmitted by a first sidelink (SL) anchor and a second wireless reference signal transmitted by a second SL anchor, wherein: the first SL anchor and the second SL anchor comprise UEs separate from the receiving UE, and the first wireless reference signal and the second wireless reference signal are transmitted for positioning of the receiving UE, performing radio frequency (RF) sensing, or both. The base device may wirelessly send, from the base device to the receiving UE, the mSL-QCL information, wherein the mSL-QCL information is indicative of the QCL relation between the first wireless reference signal and the second wireless reference signal.
