Solution Overview

Problem

In wireless communication systems, existing technologies face challenges in efficiently sharing bandwidth among multiple operators, leading to contention and reduced resource utilization efficiency, particularly in 5G communication systems that utilize higher frequency bands and advanced technologies like beamforming and MIMO.

Innovation Solution

The proposed solution involves an apparatus and method for sharing a band in a wireless communication system, where a manager device and base stations of multiple operators determine priority based on detected signals during a contention duration, allowing operators to occupy the band in an access duration based on their priority, thereby reducing contention overhead and enhancing resource utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple operators share a band using contention-based access, then resource utilization efficiency is improved, but contention overhead increases and resource utilization efficiency decreases

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidcontention overhead
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having operators perform priority determination through signal detection during a contention duration before actual band access. This preliminary priority establishment allows operators to access the band in subsequent access durations without repeated contention, reducing ongoing contention overhead while maintaining efficient resource utilization.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If operators perform priority determination through signal detection, then fair band sharing is achieved, but system complexity increases

Engineering Contradiction:
Improvefair band sharingVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies self-service by enabling operators to autonomously determine their own priority levels through detecting signals from other operators. Each operator independently assesses the band environment and establishes its priority without requiring complex centralized coordination or negotiation protocols, thereby achieving fair band sharing while limiting system complexity growth.

Inventive Principle:
Principle #25Self-service

3Productivity

If dynamic priority-based allocation is implemented, then resource utilization efficiency is maximized, but overhead for priority management increases

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidoverhead for priority management
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent applies parameter changes by utilizing the presence or absence of detectable signals as a simple binary parameter to determine operator priority. This approach enables dynamic priority-based allocation where operators with undetected signals gain higher priority, maximizing resource utilization efficiency while keeping priority management overhead minimal through straightforward signal detection rather than complex information exchange.

Inventive Principle:
Principle #35Parameter changes
