Adaptive Sleep Procedure Selection in Wireless UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face inefficiencies in power management during sleep modes, as existing procedures either waste power by constantly monitoring for page signaling or incur latency by waking up frequently, depending on the traffic rate and signaling intentions.
Innovation Solution
A user equipment (UE) selects an adaptive sleep procedure based on operating metrics such as page signaling statistics, power capability, and connectivity mode, allowing it to deactivate baseband circuitry for varying durations and attempt decoding during longer periods, optimizing power consumption and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the UE constantly monitors for page signaling during sleep mode, then the UE can quickly respond to incoming calls or messages, but the power consumption increases significantly
Solution Approach 1:
The patent applies dynamics by making the sleep procedure adaptive rather than fixed. The UE dynamically selects between different sleep procedures (first and second procedures) based on real-time operating conditions such as traffic rate and signaling intentions. This allows the system to adjust monitoring intensity flexibly, resolving the contradiction between quick response and power savings by using lighter monitoring when conditions permit and heavier monitoring when needed.
Solution Approach 2:
The patent changes the parameter of sleep procedure selection based on operating conditions. By modifying the monitoring duration and intensity parameters according to traffic rate and signaling patterns, the system optimizes the balance between response speed and power consumption. The UE adjusts these parameters adaptively rather than maintaining constant high-power monitoring.
2Reliability
If the UE wakes up frequently to check for page signaling, then the UE can ensure it doesn't miss any incoming communications, but the latency increases and power consumption rises
Solution Approach 1:
The patent employs feedback mechanisms where the UE monitors operating conditions (traffic rate, signaling intentions) and uses this feedback to select appropriate sleep procedures. This feedback loop ensures the UE maintains reliable communication by adjusting wake-up frequency based on actual network conditions, avoiding unnecessary wake-ups that would increase latency while ensuring timely response when needed.
Solution Approach 2:
The patent applies preliminary action by having the UE decode page signaling during extended sleep periods before fully waking up. This allows the UE to prepare for potential communications in advance, reducing the need for immediate full wake-ups and thereby reducing latency while maintaining reliability.
3Device complexity
If the UE uses a fixed sleep procedure, then the implementation is simple, but the system cannot adapt to varying traffic rates and signaling intentions
Solution Approach 1:
The patent transforms the fixed sleep procedure into a dynamic, adaptive system. The UE selects between different sleep procedures based on real-time conditions such as traffic rate and signaling intentions. This dynamic adaptation increases versatility while maintaining manageable complexity through structured decision logic that evaluates operating conditions and selects appropriate procedures.
Solution Approach 2:
The patent implements adaptability by changing sleep procedure parameters based on operating conditions. The system modifies monitoring duration, wake-up timing, and decoding behavior according to traffic rate and signaling patterns. This parameter adaptation enables the system to handle varying network conditions effectively while keeping the implementation organized through clear conditional logic.
