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.

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 receives a response signal set that responds to a radio signal, from an ambient internet of things (A-IoT) device set, a response signal in the response signal set being modulated by a corresponding A-IoT device in the A-IoT device set to include an identification of the corresponding A-IoT device. The reader identifies the corresponding A-IoT device based on the identification of the corresponding A-IoT device, and performs measurement for a positioning parameter. The reader executes a positioning related operation based on the identified A-IoT device and the measurement for the positioning parameter.
