Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a reader. The reader broadcasts a radio signal indicating an available slot set. The reader transmits an acknowledge (ACK) signal including a decoded sequence to an ambient internet of things (A-IoT) device. The reader receives an identifier from the A-IoT device. The identifier is a reply of the A-IoT device when there is a match between the decoded sequence and a chosen sequence, and the chosen sequence is a random sequence that responds to the radio signal in a random slot chosen from the available slot set.
