Triggered Beam Quality Measurement for Wireless Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high frequency wireless communication systems face reliability issues due to excessive transmission loss and beam mismatching, which can lead to prolonged detection times for beam quality deterioration.
Innovation Solution
Implementing a method where user equipment (UE) and base stations (BS) monitor and measure the quality of downlink and uplink beams based on trigger events, rather than periodically, to enhance real-time detection and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If beam forming technology is applied to increase receive power, then transmission loss is compensated, but beam transmission range becomes narrow and beam matching reliability deteriorates
Solution Approach 1:
The system performs preliminary beam quality measurement and evaluation before actual data transmission. The base station measures beam quality indicators (such as SINR) in advance during beam training phases, allowing it to pre-select optimal beams and avoid using beams that would lead to transmission failures, thus preventing beam matching issues before they occur.
Solution Approach 2:
The system implements continuous feedback mechanisms where the base station monitors beam quality indicators (SINR, RSRP) and compares them against thresholds. When beam quality deteriorates or falls below required levels, the system triggers beam switching to alternative beams, ensuring reliable transmission by adapting to changing channel conditions in real-time.
2Reliability
If periodic reference signal transmission is used to detect beam mismatching, then beam quality can be monitored, but detection efficiency is low and reliability is reduced
Solution Approach 1:
The system dynamically adjusts reference signal transmission based on actual transmission needs and beam quality conditions. Instead of fixed periodic transmission, reference signals are transmitted adaptively - more frequently when beam quality is marginal or changing, and less frequently when conditions are stable, optimizing both detection reliability and system efficiency.
Solution Approach 2:
The system changes the transmission parameters of reference signals based on beam quality assessments. When beam quality indicators suggest potential mismatching or deterioration, the system increases reference signal frequency or power temporarily to enhance detection capability, then returns to normal operation when stability is confirmed, balancing detection reliability with resource efficiency.

AI summary
The present application provides a method for enhancing reliability of wireless communication, comprising: monitoring, by a user equipment (UE), quality of downlink transmission between the UE and a base station (BS); and measuring, by the UE in response to a trigger event, transmission quality of at least one beam used for the downlink transmission between the UE and the BS, wherein the trigger event is used to indicate that quality of the downlink transmission between the UE and the BS does not meet a first preset condition. The present application further discloses a method, device, and system for enhancing reliability of wireless communication. By means of the solutions disclosed in the present application, transmission quality of a beam used for uplink/downlink transmission between a BS and a UE can be non-periodically measured based on event triggers, which improves real-time performance of detection and greatly enhances reliability of wireless communication.
