Diversity Transmission Service Classification for Spectrum Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diversity technologies in wireless communications have a low spectrum utilization rate due to identical service data being transmitted in multiple channels, which is inefficient for services with low reliability requirements.
Innovation Solution
Classifying services into high-priority and low-priority categories, where high-priority services are transmitted in diversity protection mode and low-priority services are transmitted in non-diversity protection mode, allowing for dynamic selection based on channel quality to improve spectrum utilization and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If diversity protection mode is used for all services, then reliability is improved, but spectrum utilization rate deteriorates
Solution Approach 1:
The patent applies local quality by differentiating service treatment based on priority levels. High-priority services receive diversity protection (reliable transmission) while low-priority services use non-diversity protection (efficient transmission). This selective approach optimizes resource allocation by applying different transmission qualities to different parts of the service flow, resolving the contradiction between reliability and spectrum utilization.
2Reliability
If identical service data is transmitted in multiple channels, then reliability is improved, but spectrum efficiency deteriorates
Solution Approach 1:
The patent segments services into high-priority and low-priority categories, applying different transmission strategies to each segment. This segmentation allows the system to allocate spectrum resources efficiently by transmitting identical data only for high-priority services across multiple channels, while low-priority services use single-channel transmission, thus reducing overall spectrum consumption while maintaining reliability where needed.
3Reliability
If diversity protection is applied to low-priority services, then reliability is improved, but resource waste increases
Solution Approach 1:
The patent changes the reliability parameter dynamically based on service priority and channel quality conditions. For low-priority services, diversity protection is disabled under normal conditions to prevent resource waste. The system only enables diversity protection for low-priority services when channel quality deteriorates below a threshold, thus adapting the reliability parameter to actual needs and avoiding unnecessary resource consumption.

AI summary
A diversity transmission method in the field of wireless communications technologies includes: classifying services to be transmitted, wherein the classifications comprise a high-priority service and a low-priority service; judging whether both channel quality of a first channel and channel quality of a second channel are higher than a set threshold value; if both the channel quality of the first channel and the channel quality of the second channel are higher than the set threshold value, sending the high-priority service and the low-priority service to the first channel and the second channel, respectively, to transmit the high-priority service and the low-priority service in a non-diversity protection way; otherwise, sending the high-priority service to the first channel and the second channel at the same time to transmit the high-priority service in a diversity protection way.
