Solution Overview

Problem

Current wireless networks face challenges in maximizing data throughput due to limited radio frequency resources and high path losses in higher frequency bands, leading to inefficient resource utilization and increased re-transmissions.

Innovation Solution

A method for wireless devices to decode resource reservation messages, measure signal characteristics, and determine whether to include reservation information in scheduling based on specified criteria, enabling efficient planning of upcoming communications and improving data throughput by optimizing resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wireless devices transmit resource reservation messages to negotiate communication resources, then resource allocation efficiency is improved, but signal loss and interference increase in higher frequency bands

Engineering Contradiction:

Improvedata throughputVSAvoidpath loss

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by having wireless devices transmit resource reservation messages in advance to negotiate and reserve communication resources before actual data transmission. This allows devices to plan upcoming communications and avoid conflicts, improving overall network efficiency despite the challenges of high-frequency transmission losses.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If wireless devices reserve communication resources for future transmissions, then re-transmissions are reduced, but system resource depletion occurs

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidsystem resources

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent implements partial action by having wireless devices selectively reserve resources only when necessary for upcoming transmissions. Devices evaluate whether resource reservation is needed based on their communication plans, avoiding unnecessary reservations that would deplete system resources while still maintaining reliability for actual data transmissions.

Inventive Principle:

Principle #16Partial or excessive action

3Productivity

If resource reservation messages include information identifying the intended receiver, then scheduling efficiency is improved, but message complexity increases

Engineering Contradiction:

Improvescheduling efficiencyVSAvoidmessage structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the resource reservation message into distinct functional components: resource identification information, intended receiver identification, and communication timing parameters. This structured segmentation improves scheduling efficiency by enabling clear identification of message elements while managing complexity through organized information architecture.

Inventive Principle:

Principle #1Segmentation
