On-Demand System Information Transmission in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face excessive overhead due to the periodic broadcasting of system information, which increases as the services diversify and terminal types evolve, leading to inefficient data transmission.
Innovation Solution
A method where user equipment (UE) requests specific system information from a network side device, allowing for on-demand transmission of required system information, reducing the overall data load by only sending necessary data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all system information is periodically broadcasted, then system information completeness is improved, but system information overhead increases
Solution Approach 1:
The system information is divided into two parts: system information that is periodically broadcasted and system information that is transmitted on-demand. This segmentation allows the network to send only the necessary information in each transmission, reducing overall overhead while ensuring completeness of information delivery.
Solution Approach 2:
The patent introduces a dynamic system information transmission mechanism where the network can switch between periodic broadcasting and on-demand transmission based on UE requests and network conditions. This dynamic approach optimizes the balance between information completeness and overhead reduction.
2Loss of information
If system information is transmitted periodically, then information availability is improved, but data transmission efficiency deteriorates
Solution Approach 1:
Instead of transmitting all system information periodically, the network transmits only the necessary portion either through periodic broadcasting or on-demand transmission. This partial action approach maintains information availability while significantly improving data transmission efficiency by avoiding redundant transmissions.
Solution Approach 2:
The patent implements a feedback mechanism where UEs can send requests for specific system information they need. The network responds to these requests by transmitting the required information on-demand, creating a feedback loop that optimizes transmission efficiency based on actual user needs.
3Loss of information
If comprehensive system information is broadcasted, then system information coverage is improved, but resource utilization deteriorates
Solution Approach 1:
The patent extracts the essential system information from the complete set and transmits only that portion periodically or on-demand. By taking out only the necessary information for operation, the system maintains comprehensive coverage for needed data while reducing resource consumption from transmitting unnecessary information.
Solution Approach 2:
The system changes the transmission parameters of system information by introducing on-demand transmission as a new mode alongside periodic broadcasting. This parameter change allows the network to adjust transmission frequency and content based on actual needs, improving resource utilization while maintaining information coverage.

AI summary
A transmission method of system information, a user equipment, a network side device, a system and a storage medium are provided. The method includes: receiving, by the UE, system information sent by a network side device, the system information is part of system information of the network side device; sending, by the UE, a request message to the network side device, wherein the request message is used to request the system information required by the UE; receiving by the UE, the system information required by the UE in on-demand system information sent by the network side device, wherein the on-demand system information is another part of system information of the network side device other than the part of system information of the network side device.
