TRP Mode Configuration via TCI Activation for Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in accurately configuring transmit receive points (TRPs) across multiple carriers, leading to potential dropped communications or interference due to mismatched TRP modes, which affects the efficiency of carrier aggregation and beam management.
Innovation Solution
The method involves receiving transmission configuration indicator (TCI) activation information that maps carriers to specific TRP mode values, allowing user equipment (UE) and network nodes to communicate using appropriate TRP modes, thereby avoiding incorrect TCI applications and ensuring consistent communication configurations across component carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carrier aggregation is implemented across multiple carriers, then communication capacity is improved, but TRP mode mismatched errors increase causing dropped communications or interference
Solution Approach 1:
The patent implements feedback mechanisms where the UE reports TCI state information and TRP mode configuration status to the network node. The network node uses this feedback to verify and adjust TRP mode assignments across carriers, ensuring consistency and preventing mismatched errors that would cause communication drops or interference.
Solution Approach 2:
The patent applies preliminary configuration actions by establishing TCI state activation information and TRP mode mappings before actual data transmission begins. The network node and UE perform configuration setup and validation in advance, ensuring that correct TRP modes are assigned to carriers before communication starts, thereby preventing errors during data transmission.
2Adaptability or versatility
If multiple TRP modes are configured across carriers, then communication flexibility is improved, but configuration complexity increases leading to potential misconfiguration
Solution Approach 1:
The patent segments the TRP mode configuration into distinct, manageable components by associating specific TCI states with specific TRP modes for each carrier. This segmentation allows the system to manage multiple TRP modes through structured, carrier-specific configurations rather than a monolithic complex setup, reducing misconfiguration errors while maintaining flexibility.
Solution Approach 2:
The patent applies local quality by assigning specific TRP modes to specific carriers based on their individual characteristics and requirements. Each carrier can have its own TRP mode configuration tailored to its specific needs, allowing flexible communication while maintaining clear, localized configuration parameters that reduce overall system complexity.
3Measurement precision
If TCI states are maintained across carriers, then beam management precision is improved, but the risk of applying incorrect TCI states increases
Solution Approach 1:
The patent uses feedback mechanisms where the UE reports received TCI state information and the network node verifies the correctness of applied TCI states. This feedback loop enables precise beam management while detecting and correcting incorrect TCI state applications before they cause harmful effects such as communication drops or interference.
Solution Approach 2:
The patent performs preliminary verification of TCI state assignments before actual beam formation and data transmission. The network node and UE validate TCI state configurations in advance, ensuring that the correct TCI states are selected and applied to the appropriate carriers, thereby preventing incorrect TCI application and its harmful effects.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive transmission configuration indicator (TCI) activation information associated with identifying a set of carriers, wherein the set of carriers maps to a set of transmit receive point (TRP) mode values. The UE may communicate on a carrier, of the set of carriers, using a TCI state of the carrier, of one or more maintained TCI states of the carrier, and a communication configuration associated with a TRP mode of the carrier, the TRP mode being based at least in part on a TRP mode value, of the set of TRP mode values. Numerous other aspects are described.
