Solution Overview

Problem

In dynamic frequency sharing scenarios, the management apparatus does not account for a secondary user's base station setting a lower output level than instructed, leading to surplus power that cannot be utilized effectively among local networks.

Innovation Solution

A control apparatus sets a transmission output value for a base station based on received instructions and notifies the management apparatus of this set value, allowing coordination of frequency resource use among local networks, even when the set value is below the instructed level.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by stationary object

If the control apparatus sets a lower output level for the base station to operate in power saving mode, then power consumption is reduced, but the surplus output cannot be utilized in other secondary use networks

Engineering Contradiction:

Improvepower consumptionVSAvoidsurplus output

Core Design Contradiction:

Use of energy by stationary objectVSLoss of energy

Solution Approach 1:

The control apparatus notifies the management apparatus of the actual output level set for the base station. This feedback mechanism allows the management apparatus to grasp the surplus output capacity and reallocate frequency resources accordingly, enabling other secondary use networks to utilize the available capacity while the base station operates in power saving mode.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The management apparatus acts as an intermediary between the control apparatus and other secondary use networks. It receives information about surplus output from the control apparatus and coordinates frequency resource allocation across multiple networks, enabling efficient utilization of available capacity without direct interaction between control apparatuses.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the management apparatus coordinates frequency resources based on instructed output levels, then interference coordination is simplified, but actual frequency resource utilization efficiency decreases

Engineering Contradiction:

Improvecoordination complexityVSAvoidfrequency resource utilization efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The control apparatus provides feedback to the management apparatus about the actual output level set for the base station. This enables the management apparatus to coordinate frequency resources based on real capacity availability rather than theoretical maximums, improving frequency resource utilization efficiency while maintaining coordination simplicity.

Inventive Principle:

Principle #23Feedback

AI summary

A control apparatus controls a base station for a local network. The control apparatus sets a transmission output value of the base station based on an instruction value received from a management apparatus that manages allocation of a frequency resource to a plurality of local networks for dynamic frequency sharing among the plurality of local networks. The control apparatus notifies the management apparatus of a set value in such a manner that the management apparatus can coordinate a use of a frequency resource among the plurality of local networks based on the set value in a case where the set value being set is below the instruction value received from the management apparatus or a transmission output value set in advance.
