16.23.1 General

A-IoT radio interface provides the communication between A-IoT device(s) and A-IoT reader, as illustrated in Figure 16.23.1-1. In this release, the A-IoT reader is a gNB-reader. A-IoT radio interface can support both inventory procedure and command procedure as defined in TS 23.369 [68]. An A-IoT device monitors the R2D message as long as it has sufficient energy.
