NR System Information Request Signaling for Omnidirectional Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no feasible technical solution for transmitting other system information in new radio (NR) wireless communication systems, which is necessary for ensuring omnidirectional coverage and reducing always-on information transmission.
Innovation Solution
The network side transmits request configuration information for other system information to the terminal, including transmission configuration details, allowing the terminal to request and receive the information on a downlink transmission port indicated by the request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network side transmits other system information periodically to ensure omnidirectional coverage, then the coverage performance is improved, but the transmission overhead and resource consumption increase
Solution Approach 1:
The patent implements periodic transmission of other system information through RMSI (Remaining Minimum System Information) blocks that are transmitted at regular intervals. The network side can configure transmission periodicity and the terminal can request updates periodically, ensuring coverage while controlling overhead by not transmitting continuously.
Solution Approach 2:
The terminal autonomously determines when to request other system information based on its needs and the configured periodicity. Instead of the network continuously transmitting all information, the terminal self-manages the information acquisition process by sending requests only when necessary, reducing overall transmission overhead.
2Productivity
If the network side transmits other system information on demand to reduce overhead, then the transmission efficiency is improved, but the response time and access delay increase
Solution Approach 1:
The network side pre-configures transmission parameters, periodicity, and resource allocations for other system information before the terminal needs them. This preliminary configuration allows the terminal to quickly request and receive information without extensive negotiation delays when actual access is needed.
Solution Approach 2:
The system implements a feedback mechanism where the terminal can request other system information by sending a request signal, and the network side responds by transmitting the requested information. This feedback loop ensures timely delivery while maintaining efficiency through on-demand transmission triggered by actual terminal needs.
