Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR wireless communication systems face challenges in efficiently configuring reference bandwidth parts (BWP) or component carriers (CC) for common transmission configuration indicators (TCI) and power control parameters, leading to suboptimal communication performance across multiple access technologies.
Innovation Solution
The implementation of a method and apparatus at user equipment (UE) and network entities to receive and transmit indications and configurations of reference BWP/CC for a common TCI pool, along with candidate sets of power control parameters, to facilitate improved communication by aligning transmission and reception beams and optimizing power control settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate TCI pools are configured for each BWP/CC, then beam alignment flexibility is improved, but device complexity and configuration overhead increase
Solution Approach 1:
The patent merges multiple separate TCI pools into a single common TCI pool that is shared across multiple BWPs and CCs. This consolidation reduces the overall configuration overhead and device complexity while maintaining the ability to provide beam alignment indications across different BWPs and CCs through a unified pool structure.
Solution Approach 2:
The common TCI pool is designed to serve multiple BWPs and CCs simultaneously, making it a universal resource that can provide beam alignment indications across different bandwidth parts and component carriers. This multi-functional approach eliminates the need for separate dedicated pools for each BWP/CC.
2Reliability
If reference BWP/CC configuration is implemented for common TCI pool, then communication consistency is improved, but system complexity increases
Solution Approach 1:
The patent introduces a reference BWP/CC as an intermediary element that mediates the relationship between the common TCI pool and multiple BWPs/CCs. This reference configuration serves as a anchor point that ensures consistent beam alignment indications across all BWPs and CCs while simplifying the overall system management through a hierarchical structure.
3Productivity
If multiple candidate sets of PC parameters are provided, then power control optimization is improved, but information processing overhead increases
Solution Approach 1:
The patent provides multiple candidate sets of PC parameters but enables the UE to selectively process only the relevant candidate sets based on current communication conditions. This partial processing approach allows for optimized power control while reducing the information processing overhead by avoiding unnecessary processing of all candidate sets in all scenarios.

AI summary
To facilitate TCI state update and activation to provide common QCL information, methods, apparatuses, and computer-readable storage medium are provided. An example method includes receiving, from a network entity (e.g., a base station), an indication indicating a reference bandwidth part (BWP) or component carrier (CC) for a common transmission configuration indicator (TCI) pool shared by a set of BWPs or CCs. The example method further includes communicating with the network entity (e.g., the base station) based on the reference BWP or CC.
