Solution Overview

Problem

Existing radio resource allocation algorithms in communications networks fail to account for human user behavior and mental state, leading to inefficient resource allocation for user-centric applications like virtual reality and immersive gaming.

Innovation Solution

Implement an AI-assisted brain-aware resource management process that considers physiological parameters of users, such as heart rate and alertness, to schedule resources based on the user's perception of quality of service.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional radio resource allocation algorithms are used, then network resources are allocated based on channel and network conditions, but resources are wasted by allocating more resources to users who cannot perceive the associated QoS gains due to cognitive brain limitations

Engineering Contradiction:

Improvenetwork resource wasteVSAvoidawareness of user perception

Core Design Contradiction:

Loss of energyVSAdaptability or versatility

Solution Approach 1:

The patent changes the parameters considered in resource allocation from purely network-centric parameters (channel state, QoS requirements) to include user-centric parameters (physiological state, cognitive brain limitations). This allows the system to adapt resource allocation to the user's actual perception capabilities, reducing waste by allocating resources based on what the user can actually perceive rather than what the network can provide.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If more resources are allocated to users, then network capacity is utilized, but energy is wasted when users cannot perceive the additional QoS improvements

Engineering Contradiction:

Improvenetwork resource utilizationVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent introduces feedback mechanisms that incorporate user physiological state information into the resource allocation loop. By continuously monitoring user cognitive state and adjusting resource allocation accordingly, the system ensures resources are allocated only when they will be perceived by the user, thereby improving energy efficiency while maintaining effective network utilization.

Inventive Principle:

Principle #23Feedback

3Productivity

If user physiological parameters are obtained and used for resource scheduling, then resource allocation efficiency is improved, but system complexity increases

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces intermediary components (sensors, processors, communication modules) that bridge the gap between user physiological state and network resource allocation. These intermediaries simplify the overall system by providing standardized interfaces and processing layers that handle the complexity of physiological parameter integration, making the system manageable while still achieving improved resource allocation efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A computer implemented method in a node of a communications network for scheduling radio resources to a user equipment, UE, in order to provide a service to a user of the UE. The method includes obtaining one or more physiological parameters of the user of the UE. The method further includes scheduling resources to the UE, based on the one or more physiological parameters, so as to provide the service to the UE with a predetermined quality of experience, as perceived by the user.
