Unified TCI Framework for Full Duplex Beam Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in efficiently implementing full duplex transmission configuration indication (TCI) across multiple channels, leading to increased overhead, latency, and power consumption, as well as inefficient use of time and frequency resources.
Innovation Solution
A unified TCI framework is introduced, where a base station transmits a common TCI state pool to user equipment (UE), enabling full duplex communications by configuring beam indications and activating TCI states for multiple channels, allowing simultaneous transmission and reception using a single transceiver component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate TCI states are configured for each channel in full duplex transmission, then channel-specific beam indication precision is improved, but system overhead and configuration complexity increase
Solution Approach 1:
The patent combines multiple channel-specific TCI states into a unified TCI framework where a single TCI state can indicate beam configurations for multiple channels simultaneously. This merging approach reduces the number of separate TCI configurations needed while maintaining the ability to provide precise beam indications for each channel through the unified state structure.
Solution Approach 2:
The unified TCI state is designed to serve multiple functions across different channels (e.g., PDSCH, PUSCH, PDCCH, PUCCH) simultaneously. A single TCI state configuration can provide beam indication for both downlink and uplink channels, reducing overall system complexity while maintaining channel-specific precision through the multi-functional design.
2Measurement precision
If multiple separate TCI states are transmitted for different channels, then beam indication accuracy is improved, but transmission overhead increases
Solution Approach 1:
The patent merges multiple channel-specific TCI indications into a single unified TCI state transmission. This unified state contains beam indication information that can be applied across multiple channels, significantly reducing the quantity of TCI state transmissions required while preserving accurate beam indication through the consolidated state structure.
3Adaptability or versatility
If full duplex TCI indication is implemented without unified framework, then channel-specific configuration flexibility is improved, but processing latency increases
Solution Approach 1:
The unified TCI framework performs preliminary configuration by establishing a single TCI state that pre-defines beam indications for multiple channels. This preliminary action eliminates the need for sequential configuration of each channel's TCI state, reducing processing latency while maintaining configuration flexibility through the unified state's ability to accommodate different channel requirements.
4Productivity
If separate TCI configurations are used for each channel, then channel optimization is improved, but power consumption increases
Solution Approach 1:
The patent merges separate TCI configuration processes into a single unified TCI state management approach. This consolidation reduces the computational overhead and processing operations required for channel optimization while maintaining the ability to optimize each channel's beam configuration through the unified state, thereby reducing overall power consumption.
