Beam-Specific System Information Transmission for Network Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile network systems face inefficiencies in energy consumption due to the broadcast of system information messages on all beams, regardless of user equipment presence, leading to unnecessary energy expenditure and lack of granularity in beam-level energy savings.
Innovation Solution
Implementing a mechanism where each beam indicates whether system information is transmitted, allowing user equipment to acquire it from alternate detectable beams if not available on the best beam, and enabling on-demand transmission on a subset of beams based on user equipment requests and active user data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If system information messages are broadcast on all beams, then user equipment can reliably acquire system information, but network energy consumption increases
Solution Approach 1:
The patent applies local quality by making system information transmission beam-specific rather than uniform across all beams. Each beam individually indicates whether it transmits system information, allowing the network to selectively activate transmission only on beams where user equipment is present or likely to be present, thereby reducing overall energy consumption while maintaining reliability for connected devices
Solution Approach 2:
The patent implements dynamics by enabling flexible, on-demand activation of system information transmission on specific beams based on real-time user equipment presence and service requirements. The network can dynamically adjust which beams transmit system information, transitioning from a static all-beams approach to a dynamic selective approach that adapts to current network conditions
2Adaptability or versatility
If system information is transmitted on multiple beams, then user equipment has more options to acquire information, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by having the network pre-indicate on which beams system information will be transmitted before user equipment attempts to acquire it. This advance notification allows user equipment to directly tune to the indicated beams without performing exhaustive scanning of all beams, thereby maintaining acquisition flexibility while significantly reducing device complexity
Solution Approach 2:
The patent introduces an intermediary mechanism where the network transmits indication information about beam-level system information transmission status. This intermediary information acts as a guide, enabling user equipment to efficiently locate system information on specific beams without having to independently analyze all possible beams, thus reducing computational complexity at the device side

AI summary
A method may include receiving on a selected beam information related to decoding a required system information at least on one or more other beams. The method may also include determining that a required system information is not broadcast on the selected beam. The method may further include receiving the required system information on one or more other detectable beams according to the information related to decoding the required system information.
