Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in efficiently monitoring Tracking Reference Signal (TRS) availability indication information, particularly in the RRC non-connected state, which affects power consumption and synchronization accuracy.
Innovation Solution
A method and apparatus for monitoring TRS availability indication information, where a terminal determines its configuration to monitor Paging Early Indication Downlink Control Information (PEI DCI) and subsequently monitors TRS availability indication information in a predetermined manner, either in the PEI DCI or paging DCI, to optimize power usage and synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal monitors TRS availability indication information in both PEI DCI and paging DCI, then synchronization accuracy is improved, but power consumption increases
Solution Approach 1:
The terminal dynamically adjusts its monitoring strategy based on configuration information. When configured to monitor both PEI DCI and paging DCI, the terminal achieves higher synchronization accuracy by cross-validating TRS availability indications from both sources. When configured for single monitoring, the terminal reduces power consumption by monitoring only one source. This dynamic adaptation resolves the contradiction between synchronization accuracy and power consumption.
Solution Approach 2:
The system changes the monitoring parameter (number of monitoring sources) based on configuration. The terminal can be configured to monitor TRS availability indication information in one or two manners, allowing the system to adjust the monitoring intensity parameter to balance synchronization accuracy requirements against power consumption constraints in different operational scenarios.
2Use of energy by moving object
If the terminal monitors TRS availability indication information in one manner only, then power consumption is reduced, but synchronization reliability deteriorates
Solution Approach 1:
The patent introduces configuration information as an intermediary that mediates between power consumption and synchronization reliability. The terminal receives configuration information that specifies whether to monitor TRS availability indication information in one or two manners. This intermediary mechanism allows the system to achieve reliable synchronization at acceptable power levels by selecting the appropriate monitoring configuration based on network conditions and terminal capabilities.
3Reliability
If the terminal wakes up earlier to monitor SSB for synchronization, then synchronization availability is improved, but power efficiency deteriorates
Solution Approach 1:
The system performs preliminary action by providing TRS availability indication information in advance through PEI DCI and/or paging DCI. Instead of waiting for the terminal to wake up and detect SSB, the network proactively indicates whether TRS will be available, allowing the terminal to plan its wake-up schedule more efficiently and avoid unnecessary early wake-ups for synchronization attempts.
Solution Approach 2:
The network provides feedback to the terminal about TRS availability through the PEI DCI and paging DCI. This feedback mechanism allows the terminal to adjust its synchronization strategy based on actual TRS availability information, avoiding wasted power consumption on synchronization attempts when TRS is not available and enabling more efficient wake-up timing when TRS is confirmed to be available.

AI summary
A method for monitoring tracking reference signal (TRS) availability indication information is performed by a terminal. The terminal determines that it is configured to monitor paging early indication downlink control information (PEI DCI); and monitors TRS availability indication information in a predetermined manner. The predetermined manner includes at least one of: a first manner of monitoring the TRS availability indicator information in the PEI DCI, and a second manner of monitoring the TRS availability indication information in paging DCI.
