Solution Overview

Problem

There is a lack of research on energy saving in network-side wireless communication systems, with existing studies focusing primarily on user equipment (UE) rather than network-side energy efficiency.

Innovation Solution

Implementing network discontinuous communication configurations, including network DRX and DTX, at various granularities such as cell, base station, MAC entity, UE, and UE group levels, with configurations sent via RRC messages, DCI, and MAC CE to manage UE behavior for energy saving.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If network discontinuous communication configuration is implemented, then network-side energy efficiency is improved, but communication reliability may deteriorate

Engineering Contradiction:
Improvenetwork-side energy consumptionVSAvoidcommunication reliability
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent implements discontinuous communication configuration where the base station periodically switches between working states (active) and sleeping states (inactive). This periodic action allows the network to reduce energy consumption by entering sleeping states during low traffic periods while maintaining the ability to wake up and restore communication when needed, thus resolving the contradiction between energy saving and communication reliability.

Inventive Principle:
Principle #19Periodic action

2Loss of energy

If discontinuous communication configuration is applied at multiple granularities, then energy saving effectiveness is improved, but system complexity increases

Engineering Contradiction:
Improvenetwork energy consumptionVSAvoidconfiguration management complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent segments the discontinuous communication configuration into multiple granularities including base station level, cell level, and MAC entity level. Each granularity can be independently configured and managed, allowing flexible energy saving strategies to be applied at appropriate levels without requiring complete system-wide reconfiguration, thus reducing overall management complexity while maintaining energy saving effectiveness.

Inventive Principle:
Principle #1Segmentation
