Solution Overview

Problem

In wireless communications systems, when the service network provides only a single component carrier, the processing engines configured for additional carriers are in an idle mode, leading to inefficient resource utilization and reduced performance.

Innovation Solution

The method involves configuring additional antennas for processing engines when the system is operating in a single component carrier scenario, allowing dynamic activation of these antennas based on the number of component carriers provided, thereby optimizing resource usage and enhancing performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If processing engines are configured for multiple component carriers, then carrier aggregation capability is improved, but resource utilization deteriorates when single component carrier is provided

Engineering Contradiction:
Improvecarrier aggregation capabilityVSAvoidresource utilization
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements dynamic configuration of processing engines that can adapt their operation mode based on the number of component carriers provided. When a single component carrier is provided, the processing engines are configured to operate in a single-carrier mode with optimized resource allocation, while maintaining the capability to switch to multi-carrier mode when needed. This dynamic adaptability resolves the contradiction by allowing the system to be versatile when needed while maintaining high resource utilization in single-carrier scenarios.

2Reliability

If additional antennas are activated for single component carrier, then diversity gain is improved, but device complexity increases

Engineering Contradiction:
Improvediversity gainVSAvoidantenna configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent designs the additional antennas and their associated processing engines to serve multiple functions. These antennas can be activated for single component carrier operation to provide diversity gain, and can be deactivated or repurposed when multiple component carriers are provided. This multi-functional design allows the system to achieve reliability improvement through diversity gain when needed, while avoiding permanent increases in device complexity by making the additional antenna configuration conditional and reversible.
