Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently coexisting between ultra-wideband (UWB) infrastructure and cellular networks, leading to potential interference during overlapping transmission schedules.
Innovation Solution
A method is proposed where a network entity determines the time gaps in the UWB transmission schedule for multiple UWB anchor nodes and schedules cellular transmissions for user equipments (UEs) during these time gaps, thereby minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cellular networks and UWB infrastructure share the same transmission spectrum, then spectrum utilization efficiency is improved, but transmission interference between the two systems increases
Solution Approach 1:
The patent segments the transmission timeline by identifying time gaps within the UWB transmission schedule and allocating these specific time intervals for cellular network transmissions. This temporal segmentation allows both systems to share the spectrum without simultaneous transmission interference, resolving the contradiction between spectrum utilization efficiency and transmission interference.
2Productivity
If cellular transmissions are scheduled during UWB transmission time, then time utilization is improved, but transmission quality deteriorates due to interference
Solution Approach 1:
The patent applies preliminary action by having the network entity first determine and identify the time gaps in the UWB transmission schedule before scheduling cellular transmissions. This advance planning ensures that cellular transmissions are only scheduled in time intervals where UWB transmissions are not occurring, thereby maintaining transmission quality while still utilizing available time resources efficiently.
3Adaptability or versatility
If the network entity determines UWB transmission schedules, then coordination between networks is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service by having the network entity automatically determine and identify time gaps in the UWB transmission schedule without requiring manual configuration or complex external coordination systems. The network entity autonomously analyzes the UWB schedule and generates appropriate cellular transmission schedules based on identified time gaps, reducing overall system complexity while improving inter-network coordination.
