Base Station Signal Resource Configuration for Terminal Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in reducing power consumption at terminals due to the need for periodic monitoring of various signals like TRS/CSI-RS, SSB, and paging signals, which leads to increased energy expenditure and potential demodulation errors.
Innovation Solution
A method where a base station configures and transmits sending resources for multiple signals, with the transceiving of one signal indicated by another, allowing terminals to determine configuration-related signal reception, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals periodically monitor multiple signals (TRS/CSI-RS, SSB, paging signals) to ensure reliable communication, then signal reception reliability is improved, but power consumption increases
Solution Approach 1:
The patent combines the indication information of multiple signals into a single Downlink Control Information (DCI) message. The DCI includes indication information for both the first signal (TRS/CSI-RS) and the second signal (SSB or paging signal), allowing the terminal to receive multiple signal indications through a single control channel, thereby reducing the number of separate monitoring operations and lowering power consumption while maintaining reception reliability
Solution Approach 2:
The Downlink Control Information (DCI) serves multiple functions simultaneously: it provides indication information for the first signal (TRS/CSI-RS), the second signal (SSB or paging signal), and enables the terminal to determine appropriate reception strategies for both signals. This multi-functional design reduces the need for separate control messages and monitoring procedures, directly addressing the power consumption issue
2Loss of information
If terminals monitor signals with different sending periods to ensure complete information reception, then information completeness is improved, but power consumption increases
Solution Approach 1:
The base station performs preliminary configuration by setting up the indication mechanism in advance. The DCI structure is pre-configured to include indication fields for both signals, and the terminal is pre-instructed on how to interpret these indications. This preliminary setup eliminates the need for complex real-time decision-making during signal monitoring, reducing processing energy while ensuring complete information reception across different sending periods
3Measurement precision
If terminals configure separate monitoring mechanisms for each signal type, then signal reception accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the indication information within the DCI structure into distinct fields: one field for the first signal (TRS/CSI-RS) indication and another field for the second signal (SSB or paging signal) indication. This segmentation allows the terminal to process each signal's indication independently through a unified framework, maintaining reception accuracy while reducing the complexity of managing multiple separate monitoring mechanisms
