UE Power-Saving Mode Detection from Target Signal Characteristics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication technologies in user equipment (UE) result in significant signaling overheads due to the network device configuring UE power-saving modes through power-saving signals for PDCCH monitoring, which is inefficient.
Innovation Solution
UE monitors target channels or signals to acquire characteristics, determining its own power-saving modes or PDCCH monitoring status without explicit network signaling, using predefined correlations or configurations.

Engineering Contradiction Analysis
1Reliability
If the network device configures UE power-saving modes through power-saving signals for PDCCH monitoring, then the UE can monitor PDCCH during CDRX on duration, but signaling overheads between the network device and UE increase
Solution Approach 1:
The UE autonomously determines the second power-saving mode by monitoring the first power-saving mode signal and deriving characteristics from it, without requiring explicit network configuration signals. The UE self-configures its PDCCH monitoring parameters based on the observed characteristics of the first power-saving mode, eliminating the need for additional network-to-UE signaling for mode configuration.
Solution Approach 2:
The network device pre-configures multiple power-saving modes with distinct characteristics before the UE needs to operate. The UE then monitors which mode is currently active by detecting these pre-established characteristics, allowing it to autonomously determine the appropriate second power-saving mode without real-time network signaling for mode selection.
2Reliability
If the UE monitors PDCCH during CDRX on duration using network-configured characteristic information, then PDCCH monitoring can be performed, but power consumption increases
Solution Approach 1:
The UE independently determines the second power-saving mode characteristics by analyzing the first power-saving mode signal, eliminating the need for continuous network signaling to maintain monitoring parameters. This autonomous operation reduces the energy required for parameter maintenance and mode switching, allowing the UE to optimize its power consumption while maintaining PDCCH monitoring capability.
3Reliability
If the network device and UE use explicit signaling to configure power-saving modes, then communication can be established, but communication efficiency decreases due to overhead
Solution Approach 1:
The UE autonomously configures its own power-saving mode parameters by monitoring and analyzing the first power-saving mode signal characteristics. This self-configuration mechanism eliminates the need for continuous network signaling to maintain mode information, significantly reducing signaling overhead and improving overall communication efficiency while maintaining reliable power-saving mode configuration.

AI summary
Embodiments of this disclosure disclose an information determining method and user equipment. The method includes: monitoring a target channel or a target signal to acquire a first characteristic, where the first characteristic is a characteristic of the target channel or the target signal; and determining first information based on the first characteristic, where in a case that the target channel or the target signal is used to indicate a first power-saving mode of the UE, the first information is a second power-saving mode of the UE; or in a case that the target channel is used to indicate whether the UE monitors a PDCCH associated with the target channel, or the target signal is used to indicate whether the UE monitors a PDCCH associated with the target signal, the first information is a second characteristic of the PDCCH or the second power-saving mode of the UE.
