AI Technical Summary
Technical Problem
Ambient Internet of Things (IoT) devices using backscattering methods in 3GPP Release 16 experience collisions at the base station due to simultaneous transmissions, leading to interference and inefficiencies in positioning methods.
Method used
Implementing multiplexed backscattering techniques by configuring wireless transmit/receive units (WTRUs) to receive reference signal transmissions with time offsets and power conditions, allowing them to transmit backscattered signals at optimized times to avoid collisions and improve positioning accuracy.
Benefits of technology
Reduces interference and enhances the accuracy of positioning methods by allowing ambient IoT devices to transmit backscattered signals at optimal times, minimizing collisions and improving network efficiency.

Abstract
Methods, architectures, devices, and systems aimed at multiplexed backscattering are described here. According to the scheme, the transmitting / receiving device (WTRU) can receive the first information indicating the first time offset relative to the first reference signal transmission. The WTRU can receive the first reference signal transmission and the second reference signal transmission. The WTRU can transmit a third reference signal based on the second reference signal transmission received at the specified first time offset relative to the first reference signal transmission, transmitting the third reference signal in response to the power condition being met.
