5G Data Transmission Slot Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication networks, especially in URLLC scenarios, the existing data transmission methods often result in significant time delays due to the need to wait for the next time slot when the available transmission duration in the current slot is less than the required duration, leading to inefficiencies and increased latency.
Innovation Solution
A method for data transmission where resource location indication information is used to facilitate data transmission within the current time slot and subsequent slots, allowing for continuous data transfer without waiting for the next time slot, thereby reducing latency and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission waits for the next time slot when current slot duration is insufficient, then transmission completeness is improved, but transmission latency increases
Solution Approach 1:
The patent segments the data transmission process into multiple parts: first transmitting available data within the current time slot, then continuing with the remaining data in subsequent time slots. This segmentation allows partial transmission completion rather than complete waiting, reducing overall latency while ensuring transmission completeness.
Solution Approach 2:
The patent performs preliminary transmission actions within the current time slot for as much data as possible before the slot ends. By advancing the transmission start position and utilizing available resources proactively, the system reduces the waiting time for the next slot while maintaining reliable transmission.
2Ease of manufacture
If data transmission uses fixed time slot boundaries, then resource allocation simplicity is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent introduces dynamic adjustment to the fixed time slot structure by allowing the transmission start position to be shifted and the transmission duration to extend into subsequent slots when needed. This dynamic approach maintains the simplicity of slot-based resource allocation while improving transmission efficiency by flexibly utilizing available resources.
3Manufacturing precision
If data transmission waits for complete time slot duration, then resource allocation accuracy is improved, but time utilization deteriorates
Solution Approach 1:
The patent ensures continuous useful action by transmitting data as soon as resources are available rather than waiting for complete slot boundaries. The transmission continues across slot boundaries when necessary, eliminating idle waiting periods and improving overall time utilization while maintaining accurate resource allocation through shifted start positions.
