Early Indication Signal Timing for Low-Power PDCCH Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment in 4G and 5G communication systems face challenges in determining the detection positions of wake-up signals (WUS), go-to-sleep signals (GTS), and physical downlink control channels (PDCCH), leading to high power consumption and inefficiency in power management during discontinuous reception (DRX) scenarios.
Innovation Solution
A method for detecting information and transmitting information that involves configuring or determining the occasions of early indication signals (WUS or GTS) and PDCCH based on time gaps, using identification information, and optimizing power consumption by reducing unnecessary blind detections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment performs blind detection of paging signals or PDCCH continuously, then detection reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by configuring the terminal to perform blind detection only during specific monitoring occasions (MOs) rather than continuously. The network configures parameters such as periodicity, offset, and duration of monitoring occasions, allowing the terminal to wake up periodically to detect WUS/PDCCH and return to sleep mode, thereby reducing power consumption while maintaining detection reliability through structured periodic monitoring.
Solution Approach 2:
The patent applies preliminary action by introducing wake-up signals (WUS) that are transmitted before the actual paging or PDCCH detection. The terminal first detects the WUS in a preliminary stage to determine whether full PDCCH detection is necessary, allowing the terminal to avoid unnecessary power-consuming blind detections while ensuring reliable detection when needed.
2Use of energy by moving object
If user equipment reduces blind detection to save power, then power consumption decreases, but detection reliability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the network configures monitoring occasion parameters based on terminal capabilities and traffic patterns, and the terminal provides feedback on detection results. The network can adjust monitoring occasion configurations based on actual usage patterns, optimizing the balance between power consumption and detection reliability through continuous feedback loops.
Solution Approach 2:
The patent applies parameter changes by allowing dynamic adjustment of monitoring occasion parameters (periodicity, offset, duration, bandwidth) based on terminal state, traffic conditions, and network requirements. This enables the system to adapt detection strategies to different scenarios, maintaining reliability while optimizing power consumption through parameter optimization rather than simple reduction.
3Adaptability or versatility
If monitoring occasion parameters are configured flexibly, then adaptability to different scenarios is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a unified monitoring occasion configuration framework that serves multiple functions and scenarios. The same configuration parameters (periodicity, offset, duration, bandwidth) are used across different terminal types, traffic conditions, and network scenarios, allowing a single flexible configuration mechanism to handle diverse requirements without requiring separate complex configuration sets for each scenario.
Solution Approach 2:
The patent implements self-service by enabling terminals to autonomously determine their monitoring occasions based on configured parameters and their own state (e.g., DRX cycle, traffic pattern). The terminal can self-adjust its detection behavior within the configured framework without requiring complex network control for each individual decision, reducing overall system complexity while maintaining flexibility.

AI summary
A method for detecting information, a method for transmitting information, a user equipment and a network device are provided. The method includes: obtaining a time gap between a first occasion and a second occasion; and determining an occasion of an early indication signal or an occasion of a PDCCH corresponding to the early indication signal based on the time gap. The first occasion is the occasion of the early indication signal, and the second occasion is the occasion of the physical downlink control channel (PDCCH) corresponding to the early indication signal.
