Radio Link Management, Beam Failure Detection and Default Beam Enhancements for High Speed Train Deployments - A simplified explanation of the abstract

This abstract first appeared for US patent application 17755679 titled 'Radio Link Management, Beam Failure Detection and Default Beam Enhancements for High Speed Train Deployments

Simplified Explanation

The patent application describes a user equipment (UE) configured to receive a configuration for a control resource set (CORESET) from a serving base station, with two transmission configuration indicator (TCI) states for a frequency resource. The UE determines reference signal (RS) resources to monitor for radio link monitoring (RLM) or beam failure detection (BFD) for beams transmitted from different transmission and reception points (TRPs) based on the TCI states.

• UE receives configuration for CORESET with TCI states for frequency resource
• First TCI state associated with beam from first TRP, second TCI state associated with beam from second TRP
• UE determines RS resources to monitor for RLM or BFD for beams from each TRP
• UE monitors RS from first TRP using first TCI state and RS from second TRP using second TCI state

Potential Applications

This technology can be applied in:

• 5G and future wireless communication systems
• Beamforming and beam management in cellular networks

Original Abstract Submitted

A user equipment (UE) is configured to receive, from a serving base station, a configuration for a control resource set (CORESET) including two transmission configuration indicator (TCI) states for a frequency resource, wherein a first TCI state is associated with a beam transmitted from a first transmission and reception point (TRP) and a second TCI state is associated with a beam transmitted from a second TRP, determine, for the beams transmitted from each of the first and second TRPs, respective one or more reference signal (RS) resources to monitor for radio link monitoring (RLM) or beam failure detection (BFD) and monitor the RS transmitted from the first TRP using the first TCI state and the RS transmitted from the second TRP using the second TCI state.
