5G NR Reference Signal Indication via Flexible Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR, the existing methods for indicating the available state of tracking reference signals (TRS) or channel state information-reference signals (CSI-RS) to user equipment (UE) lack flexibility, leading to inefficient synchronization and increased power consumption.
Innovation Solution
A method and apparatus for configuring indication information, where a base station sends an indication message with an indication identifier to a UE, allowing the UE to receive the available state of a reference signal according to various transmission modes, such as through downlink control information (DCI) signaling or System Information Block (SIB), enhancing flexibility and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station uses existing methods to indicate the available state of reference signals to UE, then the UE can synchronize with the network, but the synchronization efficiency is low and power consumption is high due to lack of flexibility
Solution Approach 1:
The patent applies dynamics by making the indication message format flexible and adaptable. The base station can dynamically select between different indication methods (first indication information with specific format or second indication information with another format) based on actual conditions, allowing the system to optimize synchronization efficiency while managing power consumption according to varying operational requirements
Solution Approach 2:
The patent utilizes parameter changes by modifying the indication message structure and content. The base station can change parameters such as the format of indication information, the wake-up cycle configuration, and the reference signal availability indicators to achieve optimal balance between synchronization efficiency and power consumption under different scenarios
2Measurement precision
If the base station sends indication messages with detailed reference signal availability information, then the UE can achieve accurate synchronization, but the message complexity and processing overhead increase
Solution Approach 1:
The patent applies segmentation by dividing the indication message into different types and formats. The base station can segment the indication information into first indication information or second indication information, each with specific structures suitable for different scenarios, thereby maintaining synchronization accuracy while reducing overall message complexity through selective usage
Solution Approach 2:
The patent implements partial action by providing the UE with only the necessary indication information required for synchronization in each specific scenario. The base station sends indication messages with appropriate detail levels - not always providing maximum detail - thereby achieving accurate synchronization when needed while reducing message complexity and processing overhead in other cases
