LP-WUS Monitoring Configuration Switching for Power-Latency Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LP-WUS monitoring configurations in wireless communication systems are often sub-optimal for current operating conditions, leading to unnecessary power consumption and increased latency at user equipment (UE), particularly in scenarios with sparse or dense data traffic.
Innovation Solution
A network node dynamically configures or reconfigures the LP-WUS monitoring configuration at a UE based on current operating conditions, using LP-WUS modification indications to adjust parameters such as monitoring periodicity, state, and window size, thereby optimizing power consumption and reducing data transfer latencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a fixed LP-WUS monitoring configuration is used, then the system operation is simple, but power consumption increases and latency increases for sparse or dense data traffic
Solution Approach 1:
The patent implements dynamic switching between different LP-WUS monitoring configurations based on traffic conditions. The network node determines whether data traffic is sparse or dense and switches the UE's monitoring configuration accordingly, transforming a static system into a dynamic one that adapts to changing conditions, thereby reducing power consumption without excessive complexity
Solution Approach 2:
The patent changes key parameters of the LP-WUS monitoring configuration including monitoring periodicity, monitoring state, and window size based on traffic conditions. By modifying these parameters dynamically, the system optimizes power consumption for both sparse and dense data traffic scenarios while maintaining manageable complexity through standardized parameter adjustment mechanisms
2Loss of time
If a fixed LP-WUS monitoring configuration is used, then the configuration management is simple, but data transfer latency increases for sparse or dense data traffic
Solution Approach 1:
The system dynamically adjusts the LP-WUS monitoring configuration based on real-time traffic conditions. By switching between configurations optimized for sparse traffic and those optimized for dense traffic, the system reduces data transfer latency adaptively while keeping configuration management complexity controlled through automated network-controlled switching
Solution Approach 2:
The patent modifies monitoring periodicity, state, and window size parameters based on traffic density. These parameter changes enable the system to optimize data transfer latency for different traffic patterns while maintaining simple configuration management through network-controlled parameter adjustment rather than complex UE-side decision-making
3Productivity
If dynamic configuration switching is implemented, then power consumption efficiency improves, but system complexity increases
Solution Approach 1:
The network node determines traffic conditions (sparse or dense) and uses this feedback to control the switching of LP-WUS monitoring configurations. This feedback mechanism enables efficient power usage by adapting to actual traffic conditions while keeping the switching mechanism relatively simple through network-side control rather than complex UE-side autonomous switching
Solution Approach 2:
The network node acts as an intermediary that manages the complexity of configuration switching. By centralizing the switching control in the network rather than requiring complex UE-side decision-making, the system achieves improved power usage efficiency while maintaining simpler device implementation at the UE side

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a low-power wake-up signal (LP-WUS) modification indication. The UE may switch from a first LP-WUS monitoring configuration to a second LP-WUS monitoring configuration based at least in part on receiving the LP-WUS modification indication. Numerous other aspects are described.
