Reference Signal Sharing for Low-Power Idle Terminal Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminals in idle or inactive states experience high power consumption due to poor channel quality, necessitating frequent synchronization with multiple SSBs for paging, which is inefficient and power-intensive.
Innovation Solution
A method where a first terminal in idle or inactive state shares reference signals from a second terminal in a connected state, utilizing notification information to determine the sending state of these signals, thereby optimizing power consumption and improving information interaction accuracy.

Engineering Contradiction Analysis
1Measurement precision
If terminals in idle or inactive states perform frequent synchronization with multiple SSBs, then synchronization accuracy is maintained, but power consumption increases significantly
Solution Approach 1:
The network device performs preliminary configuration of reference signal parameters (including SSB parameters) for terminals in idle or inactive states. By pre-configuring the necessary reference signal information, terminals can perform synchronization more efficiently without needing to frequently monitor multiple SSBs, thereby reducing power consumption while maintaining synchronization accuracy.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting reference signal configuration parameters based on terminal state and channel conditions. For terminals in idle or inactive states, the network device optimizes reference signal parameters to enable efficient synchronization with reduced monitoring requirements, thus lowering power consumption while preserving synchronization performance.
2Use of energy by moving object
If terminals share reference signals from connected state terminals, then power consumption is reduced, but information accuracy may be compromised
Solution Approach 1:
The network device acts as an intermediary by sending notification information to terminals about the sending state of reference signals. This notification mechanism ensures that terminals sharing reference signals from connected state terminals receive accurate and up-to-date information about signal availability and state, thereby maintaining information accuracy while enabling power-efficient signal sharing.
Solution Approach 2:
The patent implements feedback through notification information sent from the network device to terminals regarding reference signal sending states. This feedback mechanism allows terminals to accurately determine whether shared reference signals are currently being transmitted, ensuring information accuracy while enabling power-saving operations through efficient signal sharing.

AI summary
An information notification method is applied to a network device, and includes: sending notification information to a first terminal, the notification information being used to notify at least one of a sending state change and a sending state of a reference signal corresponding to a target port. The first terminal is in an idle state or an inactive state, the first terminal shares the reference signal of a second terminal, and the second terminal is at least one terminal in a connected state.
