Sidelink Paging DRX for Relay Terminal Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of effective solutions for how a relayed terminal monitors paging messages in a relay communication scenario, leading to increased power consumption.
Innovation Solution
The relayed terminal determines sidelink paging occasions based on the DRX mechanism to monitor paging messages on a direct communication interface, reducing the need for real-time monitoring and thus lowering power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the relayed terminal continuously monitors paging messages in real-time, then the paging message can be received promptly, but the power consumption increases significantly
Solution Approach 1:
The patent implements discontinuous reception (DRX) mechanism where the relayed terminal monitors paging messages periodically at specific paging occasions rather than continuously. The terminal determines monitoring occasions based on DRX parameters and its identity, enabling periodic action that reduces power consumption while ensuring reliable paging message reception at appropriate intervals
2Use of energy by moving object
If the relayed terminal uses DRX mechanism to monitor paging messages periodically, then the power consumption is reduced, but the paging message may be missed between monitoring occasions
Solution Approach 1:
The patent employs feedback mechanisms where the relay terminal receives paging messages from the network during its monitoring occasions and forwards them to the relayed terminal. This feedback loop ensures that paging information is reliably transmitted from the network through the relay terminal to the target device, maintaining reception reliability despite periodic monitoring
Solution Approach 2:
The system performs preliminary actions by having the relay terminal monitor and receive paging messages on behalf of the relayed terminal during predetermined monitoring occasions. This preliminary reception ensures that paging information is captured before being forwarded to the relayed terminal, preventing message loss between monitoring intervals
3Adaptability or versatility
If the relay terminal forwards paging messages to the relayed terminal, then the relayed terminal can access network paging, but the communication complexity increases
Solution Approach 1:
The patent applies universality by enabling the relay terminal to perform multiple functions: it acts as both a regular terminal for network communication and as a relay node for forwarding paging messages. The same DRX mechanism and monitoring procedures are used by the relay terminal for both its own paging and for relaying paging messages to the relayed terminal, reducing the need for separate complex protocols

AI summary
The present application provides a paging method and apparatus, and a storage medium. The method includes: the first terminal determining a sidelink paging occasion according to a discontinuous reception (DRX) mechanism, the sidelink paging occasion being an occasion for the first terminal to monitor a paging message on a direct communication interface through which communication between the first terminal and a second terminal is performed, the second terminal being a terminal that provides a relay service to the first terminal, and the paging message being a paging message from a network device for paging the first terminal; monitoring the paging message on the direct communication interface according to the sidelink paging occasion. Therefore, the monitoring of the paging message from the network device by the relayed terminal (i.e., the first terminal) in the relay scenario is realized.
