TECHNIQUES FOR POWERING PASSIVE DEVICES USING MULTIPLE TRANSMISSION/RECEPTION POINTS

Title:

TECHNIQUES FOR POWERING PASSIVE DEVICES USING MULTIPLE TRANSMISSION/RECEPTION POINTS

Document Type and Number:

WIPO Patent Application WO/2024/011499

Kind Code:

A1

Abstract:

Aspects described herein relate to enabling passive communication device operations using multiple radio frequency (RF) sources. In some aspects, multiple RF sources can synchronize timing or frequency for transmitting continuous wave (CW) signals to the passive communication device to power on the device and/or enable backscatter communication. In some aspects, power balancing can be provided to balance the power of multiple received CW signals to improve digital signal processing of the CW signals or corresponding backscatter communication.
