Channel Aggregation for Wireless Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face limitations in efficiently utilizing the electromagnetic spectrum due to the need for specific frequency bands and standards, which can lead to suboptimal performance in various communication scenarios, and legacy devices may not support channel aggregation.
Innovation Solution
The implementation of channel aggregation, where data is transmitted on multiple subchannels or channels, including licensed and non-exclusively-licensed channels, allowing for coordinated data transmission and reception, enabling compatibility with legacy devices by forming independent and properly-formed channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If channel aggregation is implemented to improve communication efficiency and bandwidth utilization, then data transmission performance is improved, but compatibility with legacy devices is degraded
Solution Approach 1:
The aggregated channel is segmented into multiple independent component channels, each capable of operating standalone. The system divides the aggregated channel resources into separate physical channels that can be independently accessed by legacy devices, while advanced devices can utilize multiple channels simultaneously for aggregated communication.
Solution Approach 2:
The channel aggregation system is designed to serve multiple functions: it supports both legacy single-channel devices and advanced multi-channel devices. Each component channel maintains universal compatibility standards, allowing any device to access individual channels, while the aggregation layer provides enhanced functionality for capable devices.
2Reliability
If multiple frequency bands are utilized to increase bandwidth and diversity gain, then communication reliability is improved, but system complexity is increased
Solution Approach 1:
Multiple frequency bands and channels are merged into a unified aggregated channel structure. The system combines resources from different frequency bands while presenting a unified interface to higher layers, reducing the perceived complexity. The aggregation manager coordinates multiple bands but abstracts their complexity, allowing reliability benefits without proportional complexity increase.
3Productivity
If coordinated data transmission on aggregated channels is implemented to optimize throughput, then data transmission efficiency is improved, but processing requirements and computational load are increased
Solution Approach 1:
Channel aggregation configuration and resource allocation are determined in advance through capability exchange and negotiation procedures. The system performs preliminary setup of aggregation parameters, channel mappings, and resource distributions before actual data transmission begins. This pre-configuration reduces real-time processing requirements during active communication.

AI summary
Multiple channels are aggregated. In an example embodiment, first data is transmitted on a first channel to a wireless device, and second data is simultaneously transmitted on a second channel to the wireless device. The first data and the second data are transmitted in a coordinated manner by aggregating the first channel and the second channel. Various example channel characteristics and combinations thereof are described. Different data allocation options for aggregated channels are described. Other alternative implementations are also presented herein.
