Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing pressure on wireless communication networks from machine-type communication data, which is characterized by small, regular data transmissions, leads to inefficient use of limited channel resources, particularly in LTE networks with limited bandwidth.
Innovation Solution
A method and device for data transmission in wireless communication networks that identify data regularity patterns in transmitted packets, allowing for optimized sending and receiving rules to reduce the need for uplink resources and improve resource utilization by either replacing regular data with temporary codes or calculating missing data based on established patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission channels are re-established for each new data transmission request, then data transmission can be performed, but control-plane overhead and resource occupation increase significantly
Solution Approach 1:
The network pre-establishes transmission channels between transmission nodes before data transmission is actually needed. These channels are maintained in a ready state and can be immediately activated when data transmission is required, eliminating the need for repeated channel establishment procedures.
Solution Approach 2:
A single pre-established transmission channel can serve multiple data transmission requests from different senders or for different data streams. The channel is designed to be reusable and multi-functional, allowing one channel to handle various communication tasks without requiring separate dedicated channels for each transmission.
2Reliability
If a dedicated transmission channel is established between every two adjacent transmission nodes, then data transmission reliability is improved, but resource occupation and spectrum usage increase
Solution Approach 1:
Multiple transmission channels are merged or shared among different data flows and transmission paths. Instead of having completely separate dedicated channels for each data stream, the system combines channel resources so that the same physical channel can carry multiple logical data streams through multiplexing techniques.
Solution Approach 2:
The transmission channel allocation is made dynamic rather than static. Channels are allocated and released based on actual transmission needs, allowing the system to adapt channel usage to changing traffic patterns. This dynamic approach ensures channels are available when needed while releasing them when not in use to free up resources.
3Adaptability or versatility
If machine type terminals enter the wireless communication network in huge numbers, then communication coverage is expanded, but pressure on capacity and channel resources becomes overwhelming
Solution Approach 1:
The network is divided into multiple transmission nodes and hierarchical levels, allowing machine type terminals to be distributed across different segments. This segmentation enables the network to handle large numbers of terminals by distributing the load across multiple nodes rather than concentrating all traffic through a single channel.

AI summary
A method and device for data transmission in a wireless communication network are disclosed. The method includes that: a data regularity of data in a transmitted data packet is acquired; a subsequent sending manner and corresponding receiving manner for the data having the data regularity are determined; and the data having the data regularity is sent according to the determined sending manner.
