Radio Frequency Chain Configuration for Carrier Aggregation Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems that employ multi-carrier aggregation and MIMO technologies consume excessive resources, as each component carrier requires separate radio frequency chains, leading to inefficient power and bandwidth usage.
Innovation Solution
A resource configuration method and device that determine the capability of user equipment, including the number of antennas and radio frequency chains, to select the least number of radio frequency chains required to meet service requirements, thereby optimizing resource allocation and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each component carrier uses separate radio frequency chains in multi-carrier aggregation, then the data bearing capacity meets service requirements, but the power consumption and resource usage increase excessively
Solution Approach 1:
The patent merges multiple component carriers into a single radio frequency chain by implementing carrier aggregation at the baseband processing level. Multiple carriers are processed together through a unified signal path, allowing them to share common radio frequency resources including the same analog-to-digital converters, mixers, and filters, thereby reducing power consumption while maintaining the required data bearing capacity
Solution Approach 2:
The patent makes a single radio frequency chain universal by enabling it to handle multiple component carriers simultaneously. The radio frequency chain is designed with multi-functional capabilities to process aggregated carriers from different frequency bands, allowing one chain to perform the work of multiple dedicated chains and thus reducing overall power consumption
2Speed
If each component carrier uses separate radio frequency chains in multi-carrier aggregation, then the transmission rate requirement is met, but the bandwidth resources are wasted
Solution Approach 1:
The patent combines multiple component carriers into a single aggregated carrier that shares common radio frequency resources. By merging the signal paths of multiple carriers, the system achieves high transmission rates through carrier aggregation while using fewer physical bandwidth resources, as the radio frequency chains are shared across multiple carriers rather than being dedicated to each individual carrier
3Productivity
If multiple radio frequency chains are used for each antenna in multi-carrier aggregation, then the system capacity is improved, but the device complexity increases
Solution Approach 1:
The patent creates universal radio frequency chains that can serve multiple component carriers and antennas simultaneously. Each radio frequency chain is designed with multi-functional capabilities to handle different carriers and antenna configurations, reducing the total number of chains required and thereby lowering device complexity while maintaining high system capacity through efficient resource sharing
