Sensing Service Scheduling to Reduce Wireless Signal Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless sensing technology is prone to interference from other signals, leading to low accuracy in determining environmental characteristics based on received signals.
Innovation Solution
A first electronic device generates a scheduling request and transmits it to a second electronic device to schedule communication services, which in turn configures sensing service interaction with a third electronic device, using configuration information to avoid interference during signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless signals are transmitted to sense the environment, then environmental characteristics can be obtained, but the receiving end is easily interfered with by other signals resulting in low accuracy
Solution Approach 1:
The patent applies preliminary action by having the management device pre-schedule communication services before sensing signal transmission. The scheduling request is sent in advance to allocate time-frequency resources, ensuring that communication services are configured to avoid interfering with the sensing signal reception, thereby improving measurement precision through proactive resource management
Solution Approach 2:
The management device acts as an intermediary between communication services and sensing services. It receives scheduling requests, determines appropriate time-frequency resources, and configures communication services accordingly, mediating to prevent interference from communication signals to sensing signal reception and thus improving environmental characteristics determination accuracy
2Productivity
If communication services are scheduled dynamically, then resource utilization improves, but interference with sensing signals increases
Solution Approach 1:
The patent applies segmentation by dividing time-frequency resources into distinct segments for communication services and sensing services. The management device segments resources based on scheduling requests, allocating specific time slots and frequency bands to communication services while protecting sensing signal resources, thereby maintaining high resource utilization without compromising sensing accuracy
Solution Approach 2:
The patent implements dynamics through flexible resource allocation where the management device dynamically adjusts communication service scheduling based on real-time sensing requirements. The scheduling can be adjusted according to channel conditions, traffic demands, and sensing priorities, enabling dynamic optimization of both resource utilization and sensing precision
