Multi-Beam System Information Decoding in 5G Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, there is a challenge in achieving a high decoding success rate for system information, which is crucial for secure service coverage, as existing methods rely on decoding signals transmitted via single beams, leading to inefficiencies and potential communication failures.
Innovation Solution
A terminal device with a processor and transceiver combines signals transmitted via multiple beams from a base station to decode system information, increasing the probability of successful acquisition by managing and storing channel qualities for each beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal decodes signals transmitted via a single beam, then the decoding process is simple, but the decoding success rate is low
Solution Approach 1:
The patent combines multiple signals received via different beams to perform joint decoding. The terminal device receives first and second signals transmitted through different beams and decodes the second signal by combining it with the first signal, thereby improving the decoding success rate while managing complexity through efficient combination strategies.
2Reliability
If a terminal combines signals from multiple beams to decode, then the decoding success rate increases, but the processing complexity increases
Solution Approach 1:
The patent applies partial action by selectively combining signals only when decoding failure is detected or when channel conditions warrant it. The terminal attempts decoding of the second signal by combining with the first signal under specific conditions, rather than always combining, thus balancing reliability improvement with processing complexity management.
3Reliability
If signals are transmitted via multiple beams, then coverage and reliability improve, but the time required to acquire system information increases
Solution Approach 1:
The patent applies preliminary action by performing channel quality measurement and beam management in advance. The terminal measures channel qualities for different beams and stores this information, enabling faster decision-making during system information acquisition without increasing the actual acquisition time, thus maintaining service coverage while reducing time loss.
