Solution Overview

Problem

Current wireless communication systems face challenges in predicting and mitigating dynamic changes in the environment that can disrupt sidelink communications, such as those between vehicles and base stations, due to factors like physical obstructions and interference, which can lead to service interruptions and reduced network performance.

Innovation Solution

The system employs vehicles equipped with sensors to actively monitor and report coordination information, allowing a network entity to predict environmental changes and select appropriate vehicles to track user equipment (UE) for improved channel estimation and interference management, thereby preventing disruptions in wireless communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If vehicles are deployed to monitor and report coordination information for predicting environmental changes, then network reliability is improved, but device complexity and system resource requirements increase

Engineering Contradiction:

Improvenetwork reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Vehicles in the C-V2X system autonomously monitor and report coordination information using their onboard sensors without requiring centralized control. Each vehicle independently performs tracking and reporting functions, reducing the need for complex centralized management infrastructure while improving network reliability through distributed monitoring.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Vehicles serve multiple functions simultaneously: they act as mobile base stations, sensors for environmental monitoring, and relay nodes for communication. This multi-functionality reduces the need for dedicated infrastructure devices, lowering overall system complexity while enhancing network reliability through diverse functional contributions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If multiple vehicles are configured to track a UE in a geographic area, then measurement precision is improved, but loss of energy increases due to continuous monitoring operations

Engineering Contradiction:

Improvecoordination information accuracyVSAvoidenergy consumption

Core Design Contradiction:

Measurement precisionVSLoss of energy

Solution Approach 1:

Instead of all vehicles continuously monitoring the UE, only a subset of vehicles within relevant geographic areas are activated to track and report coordination information. This partial action approach maintains measurement precision by deploying sufficient monitoring nodes while reducing overall energy consumption by keeping other vehicles in low-power states.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

Vehicles perform monitoring and reporting operations periodically rather than continuously. The system configures vehicles to report coordination information at specific intervals or triggered by events, maintaining accurate environmental prediction capability while significantly reducing energy consumption compared to continuous monitoring.

Inventive Principle:

Principle #19Periodic action

3Object-generated harmful factors

If vehicles use sensors to collect coordination information, then object-generated harmful factors are reduced, but use of energy increases due to sensor operations

Engineering Contradiction:

ImproveinterferenceVSAvoidvehicle energy consumption

Core Design Contradiction:

Object-generated harmful factorsVSUse of energy by moving object

Solution Approach 1:

The system replaces physical sensor-based environmental modification with information-theoretic approaches. Instead of using sensors to physically alter or block interference sources, the system collects coordination information about interference conditions and uses this data to predict and avoid harmful environmental factors through intelligent resource allocation and communication scheduling.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Techniques for wireless communications are described. A first device may receive first control signaling that may indicate a second device in a wireless communications system. The first device may then identify, based on the received first control signaling, a set of devices for tracking the second device in the wireless communications system. In some examples, the first device may then transmit second control signaling to the identified set of devices for tracking the second device in the wireless communications system. The first device may then receive, based on the transmitted second control signaling, coordination information from the set of devices. The received coordination information may be associated with the second device. The coordination information collected by the set of devices may be used to predict changes in an environment surrounding the second device. By predicting dynamic changes in the environment, disruptions in wireless communication may be prevented.
