Adaptive Search Space Monitoring for DRX Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to allow terminals to efficiently monitor power saving signals in both long and short DRX cycles due to fixed search space monitoring cycles, leading to unnecessary power consumption.
Innovation Solution
Implement a method where terminals and network devices adapt search space monitoring based on DRX cycle type, using different search spaces and configuration parameters for long and short DRX cycles, ensuring power saving signals are monitored efficiently in one appropriate space, reducing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed search space monitoring cycle is used, then the terminal can monitor power saving signals in a simple manner, but the terminal cannot normally monitor power saving signals when both long and short DRX cycles are applied
Solution Approach 1:
The patent applies dynamics by making the search space monitoring cycle adaptive rather than fixed. The terminal device determines different monitoring cycles based on the DRX cycle length: using a first monitoring cycle for long DRX cycles and a second monitoring cycle for short DRX cycles. This dynamic adjustment ensures reliable power saving signal monitoring while maintaining operational simplicity through automated cycle selection.
2Reliability
If the terminal monitors power saving signals in multiple search spaces, then the terminal can ensure signal reception, but the terminal's power consumption increases
Solution Approach 1:
The patent extracts and monitors only the necessary power saving signals in the appropriate search space based on the current DRX cycle configuration. Instead of monitoring all possible search spaces, the terminal identifies and monitors only in the first search space for long DRX cycles or the second search space for short DRX cycles. This selective extraction approach ensures reliable signal reception while minimizing power consumption by avoiding unnecessary monitoring activities.

AI summary
Embodiments of this application provide a search space monitoring method and an apparatus, and relate to the field of communications technologies, so that a terminal can normally monitor a power saving signal in a search space in a scenario in which the power saving signal can be applied to a long DRX cycle and a short DRX cycle. The method includes: when using a long DRX cycle, monitoring, by a terminal, a power saving signal in a first search space, and skipping monitoring the power saving signal in a second search space, where the power saving signal is used to indicate power saving information of the terminal; and when using a short DRX cycle, monitoring, by the terminal, the power saving signal in the second search space, and skipping monitoring the power saving signal in the first search space. This application is applicable to a search space monitoring process.
