Predicting Wireless Link Disruptions via Sensor-Based Obstruction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communications systems face challenges with unexpected physical obstructions that can temporarily disrupt communication links, particularly in dynamic environments, leading to degraded performance or failure, especially in high-frequency bands, and existing closed-loop feedback mechanisms may lack information about such obstructions.
Innovation Solution
Equipping user equipment (UE) with sensors to monitor the environment for upcoming disruptions, allowing it to predict and report potential obstructions, enabling the network entity to adjust communication links or parameters proactively to mitigate disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are added to user equipment to detect physical obstructions, then the ability to predict and report disruptions is improved, but the device complexity and power consumption increase
Solution Approach 1:
The patent applies preliminary action by using sensors to detect physical obstructions before they cause communication link failure. The UE proactively identifies upcoming disruptions and reports them to the network entity, allowing the network to switch to alternative communication links before the primary link fails, thereby preventing service interruption.
Solution Approach 2:
The patent introduces sensors as intermediary devices that mediate between the physical environment (obstructions) and the communication system. These sensors detect obstructions and provide early warning information to the network entity, enabling proactive mitigation without requiring complex changes to the core communication protocol.
2Reliability
If sensors are deployed in user equipment to monitor environment, then disruption prediction capability is improved, but power consumption increases
Solution Approach 1:
The patent applies self-service by enabling the UE to autonomously monitor its environment using onboard sensors and independently determine when obstructions threaten communication links. The UE self-manages the detection and reporting process without requiring continuous network intervention, reducing overall system power consumption while maintaining reliability.
3Duration of action of stationary object
If proactive disruption management is implemented, then communication continuity is improved, but channel capacity is consumed for reporting and switching
Solution Approach 1:
The patent applies preliminary action by reporting disruptions before they occur, allowing the network to proactively switch to alternative communication links. This prevents link failures and maintains communication continuity without requiring reactive retransmissions or recovery procedures that would consume additional channel capacity.

AI summary
Certain aspects of the present disclosure provide techniques for reporting an upcoming disruption to a communication link. An example method for wireless communications by an apparatus includes sending a report that indicates a prediction of an upcoming disruption to one or more communication links; obtaining a response to the report, wherein the response indicates to communicate via at least one communication link; and communicating with a network entity via the at least one communication link in accordance with the response.
