TECHNIQUES AND APPLICATIONS OF MANAGING BFD-RS SET CONFIGURED WITH MULTIPLE BEAMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17454018 titled 'TECHNIQUES AND APPLICATIONS OF MANAGING BFD-RS SET CONFIGURED WITH MULTIPLE BEAMS

Simplified Explanation

The abstract describes a patent application related to a base station and a user equipment (UE) in a wireless communication system. The patent application proposes a method for beam failure recovery (BFR) in the system.

  • The base station transmits a configuration set and a beam failure detection reference signal (BFD-RS) associated with a first beam to the UE.
  • The UE detects a beam failure indication (BFI) of the first beam based on the BFD-RS from the base station.
  • The UE increments a BFI counter when it detects the BFI indication of the first beam, regardless of the status of other beams.
  • The UE and the base station perform a BFR procedure when the BFI counter reaches or exceeds a certain threshold.

Potential applications of this technology:

  • Wireless communication systems using beamforming technology.
  • Cellular networks where base stations and UEs need to recover from beam failures.

Problems solved by this technology:

  • Beam failures can occur in wireless communication systems due to various factors, such as interference or physical obstacles.
  • Detecting and recovering from beam failures is crucial to maintain reliable and efficient communication.

Benefits of this technology:

  • Improved reliability: The proposed method allows for the detection and recovery of beam failures, ensuring uninterrupted communication.
  • Efficient resource utilization: By incrementing the BFI counter only for the affected beam, unnecessary resource allocation for other beams is avoided.
  • Simplified procedure: The BFR procedure is triggered when the BFI counter reaches a threshold, simplifying the recovery process.


Original Abstract Submitted

A base station may transmit, to a UE, a configuration set associated with a BFD-RS set corresponding to a plurality of beams including a first beam via an RRC message. The base station may transmit, to the UE, a BFD-RS associated with the first beam. The BFD-RS may be associated with the BFD-RS set. The UE may detect a BFI indication of the first beam based on the BFD-RS from the base station. The UE may increment a BFI counter in response to the detected BFI indication of the first beam irrespective of a status associated with other beams in the plurality of beams. The UE and the base station may perform a BFR procedure in response to the BFI counter reaching or exceeding a corresponding BFI counter threshold.
