On-Demand System Information Delivery After Paging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in transmitting system information, leading to increased power consumption, time consumption, and resource usage due to periodic broadcasts.
Innovation Solution
Implementing a system where system information is transmitted on-demand, reducing the number of repetitions needed for transmission and thereby minimizing power, time, and resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If system information is transmitted periodically through broadcasts, then all user equipment can receive the information reliably, but power consumption and resource usage increase
Solution Approach 1:
The patent implements periodic broadcasting of system information at configured intervals, allowing user equipment to receive information reliably while enabling the system to switch between periodic and on-demand transmission modes to reduce power consumption when full broadcasts are not necessary
Solution Approach 2:
The patent introduces feedback mechanisms where user equipment can request specific system information blocks through random access channels, and the network responds by transmitting only the requested information, thereby reducing unnecessary power consumption from blanket periodic broadcasts
2Loss of information
If system information is transmitted periodically, then information availability is ensured, but time consumption increases
Solution Approach 1:
The patent maintains periodic transmission of essential system information to ensure availability while reducing the frequency and scope of transmissions compared to traditional continuous periodic broadcasting, thereby reducing time consumption
Solution Approach 2:
The patent extracts and separates specific system information blocks that can be transmitted on-demand based on user equipment requests, removing them from the mandatory periodic broadcast schedule and reducing overall transmission time while maintaining information availability
3Loss of information
If system information is transmitted periodically, then all user equipment receives updates, but resource usage increases
Solution Approach 1:
The patent segments system information into multiple information blocks, with essential information transmitted periodically and less critical information transmitted on-demand based on specific requests, reducing overall resource usage while maintaining comprehensive information distribution
Solution Approach 2:
The patent implements feedback-based on-demand transmission where user equipment indicates specific information needs through random access requests, and the network transmits only those specific information blocks, significantly reducing resource usage compared to universal periodic broadcasting

AI summary
Various aspects of the present disclosure relate to techniques for transmitting on-demand system information. A network equipment (NE) is configured to transmit a first information that configures remaining minimum system information (RMSI), wherein a first part of the RMSI is configured to be transmitted in a master information block (MIB) comprising common control resource set (CORSET) information and common search space monitoring information containing scheduling information associated with a second part of RMSI, and wherein the second part of the RMSI comprises paging resource monitoring information; transmit a second information that configures at least one monitoring occasion in a physical downlink control channel (PDCCH) to transmit a first on-demand system information block (SIB1); and transmit the SIB1 after transmission of a paging message.
