SIDELINK ASSISTED INDICATION OF BEAM FAILURE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18054536 titled 'SIDELINK ASSISTED INDICATION OF BEAM FAILURE

Simplified Explanation

The abstract describes methods, systems, and devices for wireless communications at a user equipment (UE) to handle beam failures and recover communication through beam switching. Here are the key points explained in bullet points:

  • UE identifies a beam failure and determines the reasoning for the failure.
  • UE sends a Beam Failure Recovery (BFR) request to a sidelink relay UE.
  • Sidelink relay UE transmits the BFR request to the network entity.
  • Network entity receives the BFR request and identifies beam switching parameters based on the interference type.
  • Network entity includes beam switching parameters in a BFR response to the UE.
  • UE receives the BFR response and switches to another candidate beam for communication.

Original Abstract Submitted

Methods, systems, and devices for wireless communications at a user equipment (UE) are described. A UE may identify a beam failure for at least one communication beam at the UE. The UE may determine the reasoning for the beam failure and may include the reasoning in a beam failure recovery (BFR) request. The UE may identify a sidelink relay UE to communicate via sidelink channel and transmit the BFR request to the network entity. The network entity may receive the BFR request from the sidelink relay UE and identify beam switching parameters based on the type of interference that caused the beam failure. The network entity may include the beam switching parameters in a BFR response to the UE. The UE may receive the BFR response and switch to another candidate beam to enable communication to the network entity.
