US-20260128839-A1 - COMMAND COMMUNICATION FOR ENERGY HARVESTING DEVICES

Abstract

A network node may generate a command intended for an energy harvesting (EH) device, and the network node may transmit information indicating the command to each user equipment (UE) of a set of UEs. The command may be associated with configuring data on the EH device. Each of the UEs may receive, from the network node, the information indicating the command intended for an EH device, and each UE may be further configured to wirelessly transmit, to the EH device, the command associated with configuring data on the EH device. An EH device may wirelessly receive the command from a UE, and the EH device may set at least one parameter of the EH device according to the command.

Description

BACKGROUND Technical Field The present disclosure generally relates to communication systems, and more particularly, to communication of commands generated by network nodes to energy harvesting devices. INTRODUCTION Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems. These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communications (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.
