Resource Indication for Preemptive Transmission in 5G Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies face challenges in effectively indicating resource preemption for transmission, particularly when the number of downlink symbols in the time domain is less than or greater than 14, which hinders efficient resource utilization and performance in 4G and 5G systems.
Innovation Solution
A method and device for resource indication that configures a reference resource into M portions in the time domain and N portions in the frequency domain, allowing for effective indication of preempted resources through indication information, even when the number of downlink symbols is not 14, by using various granularity sets and division methods to accommodate different symbol counts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the reference resource is divided into fixed 14 blocks for preemption indication, then the indication method is simple and standardized, but it cannot adapt to scenarios where the number of downlink symbols is less than or greater than 14
Solution Approach 1:
The patent applies dynamics by making the division configuration adaptable to different numbers of downlink symbols. Instead of a fixed 14-block division, the system dynamically adjusts the division based on the actual number of symbols available, allowing the same indication mechanism to work across varying resource sizes while maintaining operational simplicity
Solution Approach 2:
The patent changes the parameter of block division from a fixed value (14 blocks) to a variable that adapts to the number of downlink symbols. By allowing M and N to be configured based on actual symbol counts, the system maintains indication effectiveness across different resource sizes without requiring fundamentally different indication mechanisms
2Reliability
If preemption indication is implemented for non-14 symbol configurations, then resource indication coverage is improved, but the configuration and indication method becomes more complex
Solution Approach 1:
The patent achieves universality by designing an indication mechanism that serves multiple purposes: it works for the traditional 14-symbol configuration and also adapts to configurations with fewer or more symbols. The same indication framework handles diverse scenarios, improving reliability across different resource sizes without requiring separate indication mechanisms for each case
Solution Approach 2:
The patent applies segmentation by dividing the reference resource into M portions in the time domain and N portions in the frequency domain, where M×N equals the number of downlink symbols. This segmented approach allows flexible configuration that adapts to different symbol counts while maintaining a systematic and manageable indication structure
3Adaptability or versatility
If flexible division into M and N portions is allowed, then adaptability to different scenarios is improved, but the configuration complexity increases
Solution Approach 1:
The patent applies segmentation by systematically dividing the reference resource into M time-domain portions and N frequency-domain portions. This structured segmentation provides flexibility for different scenarios while maintaining organizational simplicity through clear domain separation and mathematical relationship (M×N = total symbols)
Solution Approach 2:
The patent allows for partial configuration where M and N can be set according to actual needs. The system can configure division parameters to match the available resources exactly, avoiding unnecessary complexity by only dividing what is needed rather than forcing a fixed structure
