US-20260129662-A1 - COMMAND SCHEDULING FOR INTERNET OF THINGS (IoT)

Abstract

Methods and apparatuses are described herein for command scheduling in Internet of Things (IoT). A wireless transmit/receive unit (WTRU) may receive, from a base station (BS), resource configuration information that comprises one or more resource groups. Each of the one or more resource groups may comprise one or more resources. The WTRU may receive, from one or more devices, one or more respective device identifications that correspond to the one or more devices. For the one or more resource groups, the WTRU may determine whether one or more commands are pending for the one or more devices. The WTRU may select, based on one or more resources in a resource group, a device identification associated with a pending command from among the one or more device identifications. The WTRU may transmit, based on the selected device identification, the pending command using the one or more resources in the resource group.

Description

BACKGROUND Ambient Internet of Things (AIoT) services utilize IoT-enabled devices to monitor and manage environments or assets seamlessly, often in real-time, without requiring direct user intervention. In AIoT services, inventory procedures primarily involve a reader initiating access to multiple IoT-enabled devices. Additionally, the AIoT service supports command-based actions triggered through inventory and command procedures. However, these procedures require additional resources for command transmission by the reader and potential data reception from the IoT-enabled devices. Current approaches to scheduling these resources are often impractical due to the complexity of the reader and/or devices. SUMMARY Methods and apparatuses are described herein for command scheduling in Internet of Things (IoT). For example, a wireless transmit/receive unit (WTRU) may receive, from a base station (BS), resource configuration information that comprises one or more resource groups. Each of the one or more resource groups may comprise one or more resources. The WTRU may receive, from one or more devices, one or more respective device identifications that correspond to the one or more devices. For the one or more resource groups, the WTRU may determine whether one or more commands are pending for the one or more devices. The WTRU may select, based on one or more resources in a resource group, a device identification associated with a pending command from among the one or more device identifications. The WTRU may transmit, based on the selected device identification, the pending command using the one or more resources in the resource group.
