MBS Service Activation Control for Power-Efficient NR Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the NR system, MBS services may not always be available in a cell, leading to power waste in terminal devices that continue to receive configurations without checking for service availability.
Innovation Solution
A method and apparatus for managing MBS services by sending and receiving commands to deactivate or activate MBS services based on network device instructions, using DCI, MAC CE, or RRC signaling to optimize power usage and ensure service availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device continuously receives MBS configuration information without checking service availability, then the terminal device can ensure service reception readiness, but power consumption increases
Solution Approach 1:
The network device performs preliminary action by sending activation/deactivation commands in advance before the terminal device needs to receive MBS service, allowing the terminal to prepare configuration information proactively. This resolves the contradiction by enabling the terminal to maintain service readiness (improving reliability) while avoiding continuous monitoring and reducing power consumption.
Solution Approach 2:
The system implements feedback through the network device sending activation/deactivation commands based on actual MBS service availability. The terminal device receives this feedback information and adjusts its configuration accordingly, ensuring it only maintains service readiness when actually needed, thus balancing reliability with power consumption.
2Reliability
If the terminal device activates MBS service continuously, then service availability is ensured, but power waste occurs when service is not actually provided
Solution Approach 1:
The MBS service activation state is made dynamic rather than static. The network device sends activation commands when service becomes available and deactivation commands when service is unavailable. This dynamic adjustment allows the terminal device to align its power consumption with actual service needs, resolving the contradiction between ensuring service availability and avoiding power waste.
Solution Approach 2:
The system changes the parameter of service activation state based on network conditions. When MBS service is available, the activation parameter is set to true; when unavailable, it is set to false. This parameter change approach allows the terminal device to adapt its power consumption to match actual service availability, eliminating unnecessary power waste while maintaining reliability when needed.
