Beam Selection for Signal Transmission Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When transmitting data signals to a base station, terminals face the challenge of selecting beams with adequate quality, as using poor-quality beams can result in parsing errors, while waiting for better-quality beams increases latency.
Innovation Solution
A signal transmission method that assesses received beam signals for quality, transmitting verification and data signals using the best available beam initially, and switching to a second beam if the initial beam's quality is unsatisfactory, ensuring data is sent with optimal quality and minimal latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal waits for a better-quality beam to transmit data signals, then the signal quality and parsing accuracy are improved, but the transmission latency increases
Solution Approach 1:
The terminal performs preliminary beam quality assessment and preparation before actual data transmission. By evaluating beam qualities in advance and pre-selecting candidate beams, the system can quickly switch to better beams when needed without significant delay, thus reducing transmission latency while maintaining signal quality.
Solution Approach 2:
The beam selection process is made dynamic and adaptive. The terminal continuously monitors beam qualities and can switch between different beams based on real-time conditions. This dynamic adjustment allows the system to balance between using available beams (reducing latency) and waiting for better beams (improving quality), resolving the contradiction flexibly.
2Loss of time
If the terminal uses any available beam for transmission, then the transmission latency is reduced, but parsing errors may occur due to poor beam quality
Solution Approach 1:
Different beams are evaluated and selected based on their local quality characteristics. The terminal identifies which beams have adequate quality for reliable transmission and which are suitable for faster but riskier transmission. This localized quality assessment allows the system to match beam selection with transmission requirements, reducing latency when acceptable beams are available while avoiding parsing errors with poor beams.
Solution Approach 2:
The system incorporates feedback mechanisms where the terminal monitors transmission outcomes and beam qualities in real-time. Based on this feedback, the terminal can adjust its beam selection strategy, learning from previous transmission successes and failures to make more accurate future decisions, thus balancing latency and parsing accuracy.
