Data Transmission Method Using Multi-Channel Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communications systems face challenges in simultaneously achieving low delay, high reliability, and high data transmission rates, particularly in scenarios like IMT-2020 fifth generation mobile communications, where a block error rate of 10^-5 and 300 Mbps transmission within 1 millisecond are required, but current systems like LTE-Advanced struggle to meet these demands due to high retransmission rates and delays.
Innovation Solution
The method involves generating and transmitting multiple pieces of data with different sizes using transmission channels with varying delays, where smaller data is sent through a channel with lower delay and larger data through a channel with higher delay, allowing for efficient and reliable data transmission that meets the requirements of low delay and high rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted through a single channel with high capacity, then data transmission rate is improved, but transmission delay increases
Solution Approach 1:
The original data is segmented into multiple versions with different sizes (original data, compressed data, and highly compressed data). Each version is transmitted through a different channel based on its size characteristics, allowing simultaneous optimization of transmission rate and delay for different data portions.
Solution Approach 2:
The patent introduces a new dimension of data representation by creating multiple versions of the same data with different compression levels. This dimensional transformation allows the system to exploit different transmission channel characteristics for different data versions, resolving the delay-rate tradeoff.
2Speed
If data is transmitted through a channel with low delay, then transmission speed is improved, but data capacity is limited
Solution Approach 1:
The patent dynamically selects which data version to transmit based on channel conditions and requirements. When low delay is critical, highly compressed data is sent through low-delay channels. When full data capacity is needed, the original or less compressed data is transmitted through high-capacity channels, creating a dynamic adaptation mechanism.
3Productivity
If high compression ratio is applied to reduce data size, then transmission rate is improved, but data reliability decreases
Solution Approach 1:
The patent transmits multiple versions of data with different compression levels. The receiver can use the highly compressed data for quick updates when reliability requirements are moderate, while the original data provides a reliable backup for complete information recovery, achieving partial action optimization.
Solution Approach 2:
By changing the compression parameter to create different data versions, the patent allows the system to adapt to different transmission scenarios. The same information can be represented with different parameters (compression levels), enabling optimization based on channel conditions without sacrificing reliability.

AI summary
Embodiments of the present invention relate to a data transmission method, a transmit end device, and a receive end device. The method includes: generating, by a transmit end device, at least first data and second data based on to-be-transmitted data, where a size of the first data and a size of the second data are different; and sending, by the transmit end device, the first data by using a first transmission channel, and sending the second data by using a second transmission channel, where a transmission delay of the first transmission channel is different from a transmission delay of the second transmission channel. Data transmission in the embodiments of the present invention has a low transmission delay and high reliability, and can be widely applied to various communications systems, especially applicable to an IMT-2020 system.
