Wireless Network System Information Grouping for Battery Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless telecommunications networks broadcast the same system information to all user equipment in a cell, leading to unnecessary information transmission and increased battery usage as all devices receive and monitor system information blocks, even if they do not need them.
Innovation Solution
Implementing a method and network node that produce and send different system information blocks to user equipment groups based on their characteristics, using a group indicator to specify which information is applicable, allowing devices to skip irrelevant data and conserve battery power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network broadcasts the same system information to all user equipment in a cell, then all user equipment can access the system properly, but user equipment receives unnecessary information and consumes more battery power
Solution Approach 1:
The patent segments user equipment into different groups based on their characteristics and information needs. Different system information blocks are broadcast for different UE groups, allowing each group to receive only the information relevant to their specific requirements, thereby reducing unnecessary information processing and battery consumption while maintaining reliable system access for all groups.
2Reliability
If the network broadcasts comprehensive system information to all user equipment, then all operational requirements are covered, but the quantity of transmitted information increases unnecessarily
Solution Approach 1:
The patent applies local quality by providing different system information blocks tailored to specific user equipment groups. Each SIB contains information optimized for particular UE characteristics (e.g., SIB1 for mobile UEs, SIB2 for stationary UEs), ensuring that each group receives comprehensive information for their specific operational needs without receiving redundant information intended for other groups.
3Reliability
If all user equipment monitors all system information blocks, then no information is missed, but processing complexity and energy consumption increase
Solution Approach 1:
The patent introduces dynamic behavior where user equipment determines its own group based on its characteristics and selectively monitors only the system information blocks relevant to its group. This dynamic approach allows UEs to adapt their monitoring behavior to their specific needs, reducing processing complexity and energy consumption while maintaining reliable reception of all necessary information.
