mTRP Beam Reset Using TCI-TRP Association After Beam Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multiple transmit receive point (mTRP) deployments, existing wireless communication systems face challenges in efficiently managing beam failures and resetting beams associated with transmission configuration indicator (TCI) states to maintain stable connections.
Innovation Solution
The method involves identifying beam failures and resetting beams by communicating configuration information related to the association between TCI states and TRPs, enabling network devices and user equipment to adjust their beam associations accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam failure is detected in mTRP deployment, then connection stability deteriorates, but implementing beam reset procedures increases system complexity
Solution Approach 1:
The patent segments the beam management process by associating each TCI state with a specific TRP identifier. When beam failure is detected, only the beam associated with the failed TRP needs to be reset, rather than managing all beams globally. This segmentation enables targeted beam recovery procedures that reduce overall system complexity while maintaining connection stability.
Solution Approach 2:
The patent introduces an intermediary mechanism where the TRP identifier associated with each TCI state serves as a mediator between beam failure detection and beam reset execution. This intermediary enables the system to identify which specific beam needs resetting without requiring complex global beam management, thus resolving the contradiction between reliability and complexity.
2Reliability
If beam reset is performed for all TCI states upon beam failure, then connection stability improves, but communication overhead increases
Solution Approach 1:
The patent applies local quality by performing beam reset only for the specific TCI state associated with the failed TRP, rather than resetting all TCI states globally. The TRP identifier enables precise localization of the failed beam, allowing the system to apply recovery actions only where needed, thus reducing communication overhead while maintaining connection stability.
Solution Approach 2:
The patent changes the parameter association by linking each TCI state to a specific TRP identifier. This parameter change enables the system to identify and reset only the affected beam based on the TRP identifier, rather than performing blanket resets of all beams, thereby reducing communication overhead while maintaining reliability.
3Measurement precision
If association information between TCI states and TRPs is maintained, then beam recovery precision improves, but memory requirements increase
Solution Approach 1:
The patent implements partial action by maintaining association information only for the necessary TCI state-TRP pairs required for beam recovery, rather than storing complete beam management information for all possible scenarios. This selective storage approach achieves sufficient beam recovery precision while minimizing memory requirements.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying an association between a transmission configuration indicator (TCI) state and a transmit receive point (TRP). The UE may identify a beam failure associated with the TRP. The UE may communicate with one or more network devices to reset a beam associated with the beam failure, for the TCI state, based at least in part on the association between the TCI and the TRP. Numerous other aspects are described.
