Wireless Terminal System Information Reception Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, terminals continuously allocate and use radio resources even when there are no service data to communicate, leading to inefficiency and unnecessary power consumption, as they need to constantly receive updated system information from base stations, even if it hasn't changed.
Innovation Solution
Implementing a method where the base station transmits system information with a minimum radio resource usage by setting specific periods for system information modification and transmission, allowing terminals to determine if updates are needed and only receive new information within these designated periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals continuously receive system information updates from base stations, then system information reliability is improved, but radio resource usage and power consumption increase unnecessarily
Solution Approach 1:
The base station transmits system information modification indication in advance before the actual modification occurs. This allows the terminal to prepare for potential updates and only activate full reception when the indication confirms a change, avoiding unnecessary continuous monitoring and reducing power consumption while maintaining reliability.
Solution Approach 2:
The base station provides feedback information (modification indication) to the terminal about system information changes. This feedback mechanism enables the terminal to adjust its reception behavior dynamically - receiving full system information only when modifications are indicated, thus balancing reliability requirements with power consumption reduction.
2Reliability
If terminals continuously monitor for system information updates, then system information reliability is improved, but radio resource efficiency deteriorates
Solution Approach 1:
The base station performs preliminary transmission of modification indications before actual system information changes occur. This allows the terminal to remain in a low-power state until needed, and only activates full system information reception when the preliminary indication confirms a modification, thereby improving radio resource efficiency while maintaining reliability.
Solution Approach 2:
The system implements periodic transmission of system information at predetermined intervals rather than continuous transmission. The base station transmits system information periodically, and the terminal monitors only during these predetermined periods, reducing radio resource usage while ensuring reliability through timely updates.
3Reliability
If base stations transmit system information continuously, then terminal reception reliability is improved, but radio resource usage increases unnecessarily
Solution Approach 1:
The base station transmits modification indications in advance of actual system information changes. This preliminary action allows the terminal to prepare for updates only when necessary, avoiding continuous transmission and reducing radio resource waste while maintaining reception reliability through targeted updates.
Solution Approach 2:
The base station transmits system information periodically at predetermined intervals rather than continuously. This periodic transmission approach ensures terminal reception reliability by providing timely updates while minimizing radio resource usage by transmitting only when updates are actually needed.

AI summary
Disclosed is the method for informing, by a wireless communication system, to a terminal about information required for reception when the terminal is connected to the wireless communication system, in which a base station updates system information according to a preset period, and the terminal efficiently receives or checks any update of the system information based on the period.
