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 20240163065 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.

• User equipment (UE) receives configuration for a control resource set (coreset) from a base station.
• The coreset includes two transmission configuration indicator (TCI) states for a frequency resource.
• Each TCI state is associated with a beam transmitted from a specific TRP.
• UE determines RS resources to monitor for RLM or BFD for beams from different TRPs based on TCI states.

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.
