Dynamic Measurement Signal Control for 5G Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, there is a challenge in efficiently using non-always-on measurement signals, particularly in high-frequency bands, where the sparse sending density of synchronization signals and CSI-RSs leads to inadequate measurement accuracy for mobility management, especially in connected states.
Innovation Solution
A message processing method and apparatus that determines whether to send a first message to a second radio access network device based on association information and information about the sending status of measurement signals, allowing the second radio access network device to decide whether to start sending its measurement signals, thereby optimizing the utilization of non-always-on measurement signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If non-always-on measurement signals (CSI-RS) are sparsely sent to reduce overhead and energy consumption, then energy efficiency and resource utilization improve, but measurement accuracy for mobility management deteriorates
Solution Approach 1:
The patent implements dynamic control of measurement signal transmission by introducing a triggering mechanism. The network device determines whether to send CSI-RS based on terminal measurement reports and predefined triggering conditions. This transforms the static always-on transmission mode into a dynamic on-demand mode, allowing the system to adapt transmission behavior to actual network conditions, thereby reducing unnecessary energy consumption while maintaining measurement accuracy when needed.
Solution Approach 2:
The patent changes the transmission parameter state of measurement signals from continuous to conditional. By introducing triggering conditions that monitor terminal measurement reports and system conditions, the transmission parameters (whether to send or not send) are dynamically adjusted. This parameter change enables the system to switch between transmission and non-transmission states based on actual needs, resolving the contradiction between energy saving and measurement accuracy.
2Productivity
If measurement signals are sent on-demand rather than always-on, then resource utilization improves, but the complexity of controlling signal transmission increases
Solution Approach 1:
The patent segments the measurement signal transmission control into distinct functional modules: a measurement report receiving module that collects terminal feedback, a triggering condition judgment module that evaluates predefined conditions, and a transmission control module that executes the decision. This segmentation of control functions simplifies the overall system architecture by breaking down the complex control task into manageable, independent components with clear interfaces.
Solution Approach 2:
The patent implements preliminary configuration of triggering conditions and measurement report formats before actual measurement and transmission operations. The network device pre-configures the terminal with measurement parameters, reporting formats, and triggering conditions. This preliminary action prepares the system in advance, reducing the complexity of real-time control decisions and enabling efficient on-demand transmission without increasing operational complexity.

AI summary
Provided are a message processing method and apparatus, a radio access network device, and a storage medium. The method includes: after receiving information about a first measurement signal of a second radio access network device reported by a terminal, a first radio access network device performing following operations: determining whether to send a first message to the second radio access network device according to obtained association information and first information, where the association information indicates association between the first measurement signal and a second measurement signal of the second radio access network device, and the first information indicates whether the second measurement signal is being sent; or sending the first message to the second radio access network device. The first message carries the information about the first measurement signal.
