System Information Transmission Segmentation for Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems transmit all system information by broadcasting, even though not all User Equipment (UE) within the coverage of a base station need all the information, leading to inefficient resource usage and unnecessary transmission of redundant data.
Innovation Solution
A method and device for transmitting system information that determines the type of information to be transmitted, allowing for broadcasting when the base station triggers the information (first system information) and unicasting or broadcasting when the UE triggers the information (second system information), optimizing the transmission mode based on the quantity of information and the number of UE to conserve resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all system information is transmitted by broadcasting, then all UE within coverage can receive the information, but resource usage becomes inefficient and redundant data is transmitted
Solution Approach 1:
The patent segments system information into two categories: first system information (broadcasting-triggered) and second system information (UE-request-triggered). This segmentation allows different transmission methods to be applied to different information types, reducing redundant broadcasts while ensuring critical information reaches all UE.
Solution Approach 2:
The patent implements dynamic transmission mode selection based on the triggering source. When the base station triggers system information transmission, broadcasting is used for wide coverage. When UE triggers the transmission, unicast or targeted broadcasting is used, dynamically adapting the transmission method to the specific scenario to reduce resource waste.
2Loss of information
If system information is transmitted by broadcasting to all UE, then information availability is maximized, but unnecessary data transmission occurs for UE that do not need the information
Solution Approach 1:
The patent applies local quality by tailoring the transmission method to the specific information type and triggering source. First system information uses broadcasting for maximum availability, while second system information uses unicast or targeted approaches, providing locally optimized transmission quality matching the specific needs of each information category.
Solution Approach 2:
The patent uses partial action by transmitting system information only when triggered, rather than continuously broadcasting all information. The base station transmits first system information when triggered and second system information when UE requests it, avoiding excessive transmission of information that is not currently needed.
3Area of stationary object
If broadcasting is used for all system information transmission, then transmission reach is maximized, but transmission efficiency decreases due to redundant transmissions
Solution Approach 1:
The patent dynamically adjusts the transmission mode based on the triggering source and information type. Broadcasting is used for first system information to maximize coverage area, while unicast or targeted methods are used for second system information to improve transmission efficiency by reducing redundant transmissions to UE that do not need the information.
Solution Approach 2:
The patent segments system information transmission into two distinct pathways: broadcasting for first system information (maximizing coverage) and unicast/targeted transmission for second system information (improving efficiency). This segmentation resolves the contradiction by applying different transmission strategies to different information categories.

AI summary
A method for transmitting system information. The method may include: determining an information type of system information to be transmitted, wherein the information type is configured to indicate a network device that triggers the system information; transmitting the system information to User Equipment (UE) within the coverage of a base station by broadcasting when the system information is first system information, wherein the first system information is triggered by the base station; and transmitting the system information to the UE by unicasting or broadcasting, wherein the second system information is triggered by the UE.
