Base Station Signaling for UE Energy Harvesting Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack mechanisms for signaling resources available for energy harvesting (EH) to user equipment (UE), limiting the efficiency of EH from uplink and downlink transmissions.
Innovation Solution
A method where a base station identifies available resources for EH and transmits an indication to a UE, allowing the UE to determine whether to harvest energy from specific resources based on the received indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station transmits detailed resource availability information to all UEs, then energy harvesting efficiency is improved, but network signaling overhead and complexity increase
Solution Approach 1:
The base station performs preliminary identification of resources available for energy harvesting before UE operations, and transmits this information in advance through system information blocks or dedicated signaling. This allows UEs to plan their energy harvesting operations beforehand, improving efficiency while concentrating the computational burden at the base station rather than distributing complexity across all devices
Solution Approach 2:
The patent introduces an intermediary information structure (resource availability indication) that mediates between the base station's resource management and UE energy harvesting decisions. This intermediary layer translates complex network resource states into simplified indicators that UEs can process efficiently, reducing the signaling complexity burden on both ends
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables more efficient energy harvesting by allowing UEs to selectively harvest energy from transmissions over indicated resources, improving energy utilization and reducing power consumption.
Implementation Method 1
determining to harvest energy from a transmission over at least one of the one or more resources available to the UE for EH

AI summary
Systems, methods, and devices for wireless communication that support mechanisms for signaling resources available for energy harvesting (EH) to a UE in a wireless communication system. In aspects, a base station transmits an indication to an UE of resources (e.g., time and/or frequency resources) available to the UE for EH. The resources may include resources over which uplink transmissions are transmitted from one or more UEs and/or resources over which downlink transmission are transmitted from the base station to the one or more UEs. The base station may include additional information in the indication to the UE. In aspects, the indication from the base station to the UE of the resources available for EH and/or the additional information may enable the EH UE to more efficiently harvest energy from the uplink transmissions from neighboring UEs and/or downlink transmissions from the base station.
