Base Station Reception Enhancement Control

Solution Overview

Problem

There is a conflict between mobile terminals seeking to conserve power by disabling reception enhancement functionalities and the network's need for improved reception performance, especially during high load conditions, as terminals do not consider the overall network state when activating these features.

Innovation Solution

A base station is configured to generate and transmit messages to mobile terminals, requesting the activation of reception enhancement functionalities such as receive diversity, equalization, and interference cancellation, even if the terminal would otherwise choose to save power, thereby balancing power consumption and network resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mobile terminals activate reception enhancement functionalities (receive diversity, equalization, interference cancellation), then reception performance is improved, but power consumption increases

Engineering Contradiction:

Improvereception performanceVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic control of reception enhancement functionalities by having the base station send activation indications to terminals based on real-time network load conditions. The terminal switches between using and not using these functionalities dynamically, rather than maintaining a fixed state, thus adapting power consumption to actual network requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The base station monitors network load conditions and sends feedback indications to terminals regarding whether reception enhancement functionalities should be activated. This feedback mechanism allows the network to control terminal behavior based on overall system state, resolving the contradiction by coordinating individual terminal decisions with network-wide requirements.

Inventive Principle:

Principle #23Feedback

2Use of energy by moving object

If mobile terminals disable reception enhancement functionalities to save power, then power consumption is reduced, but network reception performance deteriorates during high load conditions

Engineering Contradiction:

Improvepower consumptionVSAvoidnetwork reception performance

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The base station monitors network load conditions and sends feedback indications to terminals regarding whether reception enhancement functionalities should be activated. This feedback mechanism allows the network to control terminal behavior based on overall system state, resolving the contradiction by coordinating individual terminal decisions with network-wide requirements.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The base station proactively sends activation indications to terminals before performance degradation occurs during high load conditions. By anticipating the need for enhanced reception capabilities and pre-configuring terminals to activate these functionalities, the network prevents performance deterioration while managing power consumption efficiently.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If terminals autonomously decide to activate reception enhancement functionalities, then reception performance is improved, but network coordination and resource distribution become inefficient

Engineering Contradiction:

Improvereception performanceVSAvoidnetwork resource distribution efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The base station monitors network load conditions and sends feedback indications to terminals regarding whether reception enhancement functionalities should be activated. This feedback mechanism allows the network to control terminal behavior based on overall system state, resolving the contradiction by coordinating individual terminal decisions with network-wide requirements.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The base station acts as an intermediary between network conditions and terminal decisions. Rather than terminals making autonomous decisions or the network directly managing each terminal's functionality, the base station translates network state into simplified activation indications, efficiently coordinating terminal behavior with network resource distribution needs.

Inventive Principle:

Principle #24Intermediary (Mediator)
