Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In communications networks, there are scenarios where data transfer is limited by imbalanced uplink (UL) and downlink (DL) capabilities, particularly in energy-limited or resource-constrained nodes, leading to inefficient energy use and underutilization of spectral resources.

Innovation Solution

A method where a first node predicts the content of data to be transferred from a second node, allowing the second node to infer the data without direct transmission, leveraging the second node's limited resources and utilizing the first node's more substantial downlink resources for data transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the second node transmits data directly to the first node using uplink resources, then data transfer is achieved, but energy consumption increases and uplink resources are insufficient

Engineering Contradiction:

Improvedata transfer rateVSAvoidenergy consumption of second node

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

Instead of the second node transmitting data to the first node directly, the patent inverts the approach by having the first node predict and generate the data, then transmit it back to the second node. This inversion allows the energy-limited second node to avoid transmission while still receiving the needed data through downlink resources.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces prediction as an intermediary mechanism. The first node uses prediction algorithms to generate anticipated data packets, acting as a mediator that creates data representations without requiring the second node to perform energy-intensive transmission operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If uplink resources are allocated for data transmission, then data can be transferred from second node to first node, but downlink bandwidth is reduced

Engineering Contradiction:

Improveuplink data transfer capabilityVSAvoiddownlink bandwidth

Core Design Contradiction:

ProductivityVSArea of stationary object

Solution Approach 1:

The patent inverts the traditional uplink transmission model by utilizing downlink resources for data transfer. Instead of allocating uplink resources from second node to first node, the system uses downlink resources from first node to second node, effectively swapping the resource allocation direction.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If the second node performs direct data transmission, then accurate data delivery is achieved, but resource utilization is inefficient

Engineering Contradiction:

Improvedata delivery accuracyVSAvoidresource utilization efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The first node performs preliminary data generation through prediction before actual transmission is needed. By anticipating what data the second node needs to send and generating it in advance, the system ensures accurate data delivery while avoiding inefficient resource usage during the transmission phase.

Principle #10Preliminary action

AI summary

A method in a first node of transferring data from a second node to a first node comprises receiving a message from the second node indicating that the second node has data to transfer to the first node. The method then comprises predicting a possible content of the data and sending the prediction of the possible content of the data to the second node. The method then comprises determining the data based on a response of the second node to receiving the prediction.
