Solution Overview

Problem

Wireless communication systems face challenges in managing conflicts between energy harvesting and wireless communication operations, leading to degraded coexistence and potential power loss or dropped communications due to static priority levels and inefficient signaling.

Innovation Solution

Implementing dynamic priority levels for energy harvesting intervals based on the energy state of the UE, reducing overhead and latency through multiplexing priority indications with uplink communications and periodic updates, and assigning specific priority levels to different types of wireless communications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If static priority levels are used for energy harvesting intervals, then device complexity is reduced, but coexistence between energy harvesting and wireless communication is degraded

Engineering Contradiction:

Improvepriority level managementVSAvoidcoexistence of EH and communication

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent implements dynamic priority level adjustments for energy harvesting intervals based on the UE's energy state. The network entity receives energy state information from the UE and configures appropriate priority levels dynamically, allowing the system to adapt between static and dynamic operation modes depending on conditions.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If dynamic priority levels are implemented based on energy state, then coexistence and flexibility are improved, but signaling overhead and device complexity increase

Engineering Contradiction:

Improveenergy harvesting prioritizationVSAvoidpriority level management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic priority adjustment selectively rather than continuously. The network entity configures priority levels based on energy state information only when necessary, and can revert to static configurations otherwise, reducing the overall complexity burden while maintaining adaptability when needed.

Inventive Principle:

Principle #16Partial or excessive action

3Productivity

If frequent energy harvesting updates are performed, then power management efficiency is improved, but latency and communication reliability are degraded

Engineering Contradiction:

Improvepower management efficiencyVSAvoidlatency in communication

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements periodic energy state reporting and priority level configuration updates rather than continuous updates. The UE reports energy state information at configured intervals, and the network entity adjusts priority levels periodically based on these updates, balancing efficiency improvements with latency reduction.

Inventive Principle:

Principle #19Periodic action

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a first priority level for an energy harvesting (EH) interval of the UE. The UE may perform wireless communications or EH in the EH interval, based at least in part on the first priority level for the EH interval. Numerous other aspects are described.
