Solution Overview
Problem
Existing communication systems face challenges in managing beam connections effectively in Multiple-Input Multiple-Output (MIMO) technologies, particularly in Long Term Evolution (LTE) systems, which affects the quality of signal transmission.
Innovation Solution
A method where a terminal device sends characteristic information of each beam to a network device, allowing the network device to determine a target beam based on this information, and the terminal device performs beam management accordingly, including beam switching and auxiliary connection establishment or deletion, to improve signal quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device sends characteristic information of each beam to the network device for beam management, then the quality of signal transmission is improved, but the device complexity and signaling overhead increase
Solution Approach 1:
The patent segments beam management into two distinct phases: beam identification (where the terminal device determines candidate beams based on channel quality) and beam confirmation (where the network device confirms the target beam). This segmentation reduces the complexity burden on the terminal device while maintaining signal transmission quality.
Solution Approach 2:
The terminal device performs preliminary beam measurement and identifies candidate beams before reporting to the network device. This preliminary action filters out poor beams in advance, reducing the search space and complexity for both devices while ensuring only quality beams are considered for connection.
2Reliability
If beam scanning is performed in a cell with multiple beams, then the coverage and signal quality are improved, but the time consumption and resource allocation complexity increase
Solution Approach 1:
Instead of exhaustively evaluating all possible beams, the patent implements partial beam scanning where the terminal device identifies a limited set of candidate beams based on channel quality thresholds. This partial action approach achieves sufficient signal quality without the time cost of complete beam scanning.
Solution Approach 2:
The terminal device performs preliminary channel quality measurement and pre-screens beams before formal beam management procedures. This preliminary filtering reduces the number of beams that require detailed evaluation and confirmation, thereby reducing overall time consumption.
3Adaptability or versatility
If the terminal device performs beam switching and auxiliary connection management, then the adaptability to channel conditions is improved, but the operation complexity increases
Solution Approach 1:
The terminal device autonomously performs beam measurement, candidate beam identification, and auxiliary connection management without requiring complex network device intervention. This self-service approach improves adaptability to changing channel conditions while keeping operation simple through automated decision-making based on pre-defined criteria.
Solution Approach 2:
The system implements feedback mechanisms where the terminal device continuously monitors channel quality and automatically triggers beam switching or auxiliary connection establishment when quality thresholds are breached. This feedback-driven operation maintains high adaptability while keeping operational complexity low through rule-based automatic responses.
