Solution Overview

Problem

Existing wireless LAN systems face issues with mutual interference leading to communication loss and quality deterioration, and existing technologies fail to adequately improve communication characteristics while maintaining impartiality with adjacent networks.

Innovation Solution

A communication apparatus and method that allows base stations and subordinate terminals to share communication situation information, enabling control of parameters like detection threshold values and transmission power to improve network impartiality and overall communication quality by adjusting to the communication situations of neighboring networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If transmission power control is implemented in wireless LAN systems, then communication quality can be improved, but mutual interference between networks cannot be sufficiently resolved and impartiality with adjacent networks is not maintained

Engineering Contradiction:
Improvecommunication qualityVSAvoidmutual interference between networks
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements a feedback mechanism where the base station receives communication situation information from other base stations, evaluates whether control is permissible based on this feedback, and adjusts transmission power accordingly. This closed-loop feedback system enables dynamic adaptation to network conditions while maintaining impartiality with adjacent networks.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces communication situation information as an intermediary element that mediates between different networks. By sharing and evaluating this information, base stations can make informed decisions about transmission power control that consider the impact on adjacent networks, thus resolving mutual interference while maintaining fairness.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Power

If transmission power is increased to improve communication characteristics, then signal strength improves, but interference with adjacent networks increases and impartiality deteriorates

Engineering Contradiction:
Improvetransmission powerVSAvoidinterference with adjacent networks
Core Design Contradiction:
PowerVSObject-generated harmful factors

Solution Approach 1:

The patent dynamically changes transmission power parameters based on evaluated communication situation information. By adjusting this parameter in response to network conditions and impartiality considerations, the system optimizes communication characteristics while preventing excessive interference with adjacent networks.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent makes transmission power control dynamic rather than static. The base station continuously evaluates communication situation information and adjusts transmission power in real-time, enabling adaptation to changing network conditions while maintaining fair coexistence with adjacent networks.

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If transmission power control is implemented to resolve interference, then mutual interference decreases, but communication opportunities are lost and network productivity deteriorates

Engineering Contradiction:
Improvemutual interference between networksVSAvoidcommunication opportunities
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent applies partial control by evaluating whether transmission power control is permissible before executing it. Rather than uniformly reducing power to eliminate interference, the system selectively applies control only when communication situation information indicates it is appropriate, thus maintaining communication opportunities while resolving interference.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent takes preliminary action by evaluating communication situation information before implementing transmission power control. This preliminary evaluation prevents unnecessary control actions that would reduce communication opportunities, while still preparing to address interference when genuinely needed.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

The present technology relates to a communication apparatus and a communication method that can improve a communication characteristic. The communication apparatus is a base station and includes a control section configured to determine, on the basis of first communication situation information regarding a communication situation of the base station and second communication situation information regarding a communication situation received from another base station, whether or not it is permissible to carry out control of a communication parameter in the base station, and determine, on the basis of the first communication situation information and the second communication situation information, whether or not it is permissible to transmit first control request information regarding a control request of a communication parameter in the other base station. The present technology can be applied, for example, to a wireless LAN system.
