Problem

Mobile communication systems face challenges in sensing environmental objects that obstruct direct propagation paths, leading to negative impacts on communication quality, necessitating improved sensing technologies for timely and effective intervention.

Innovation Solution

The integration of cooperative sensing with timing alignment, utilizing radio-frequency signal echoes to detect objects and trigger high-priority scheduling requests (SR) for uplink resource allocation, with features like multiple SR copies, grant-based or grant-free resources, and short periodicities to ensure low-latency and high-reliability alarm-request transmissions.

Engineering Contradictions & Design Principles

1Measurement precision

If sensing technologies are integrated into mobile communication systems to detect environmental objects, then the ability to detect and respond to propagation path obstructions is improved, but the system complexity and processing requirements increase

Engineering Contradiction:

Improveobject detection capabilityVSAvoidsensing system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines sensing functions with existing communication infrastructure by utilizing radio-frequency signals already present in the communication system for both communication and sensing purposes. The base station and user equipment perform both communication and sensing operations using shared hardware resources, merging two functions into a unified system that reduces overall complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The communication system components (base station, user equipment) are designed to perform multiple functions - both communication and sensing - using the same radio-frequency signals and hardware. This multi-functionality allows the system to detect environmental objects while maintaining communication capabilities without adding dedicated sensing hardware.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If high-priority scheduling requests with multiple copies and short periodicities are used for alarm transmissions, then the reliability and latency of alarm requests are improved, but the uplink resource consumption increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system pre-configures grant-free uplink resources and establishes short periodicity scheduling for alarm requests in advance. This preliminary setup allows user equipment to immediately transmit alarm requests with high priority when needed, without waiting for dynamic scheduling decisions, thereby improving response time and reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements dynamic priority handling where alarm requests are assigned higher priority than regular data transmissions. The scheduling mechanism dynamically adjusts resource allocation based on request type, providing multiple copies of alarm requests while maintaining flexibility in resource management to balance reliability improvements with resource consumption.

Inventive Principle:

Principle #15Dynamics

3Use of energy by moving object

If the system operates in power-saving mode to reduce energy consumption, then the energy efficiency is improved, but the responsiveness to environmental obstructions deteriorates

Engineering Contradiction:

Improvedevice energy consumptionVSAvoidresponse speed to obstructions

Core Design Contradiction:

Use of energy by moving objectVSSpeed

Solution Approach 1:

The system implements periodic monitoring of scheduling request buffers even during power-saving mode. User equipment periodically checks for alarm requests and can immediately transmit them when detected, maintaining responsiveness to environmental obstructions while spending most time in low-power state to conserve energy.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system enables user equipment to autonomously detect and transmit alarm requests without continuous network control. The device monitors its own buffer status and self-initiates high-priority transmissions when alarm conditions are detected, maintaining fast response capability while minimizing energy consumption by avoiding continuous network interaction.

Inventive Principle:
