Demo: UE Assisted Ambient Internet of Things in LTE Downlink, Energy Autonomous


Ambient power enabled Internet of Things (AIoT) defined 3GPP is promoted as the next generation communication standard, 6G. AmBC is a communication technique aiming to zero-energy device (ZED) for massive Machine Type Communications (mMTC). This paper suggests a user equipment (UE) assisted AIoT, based on Long-Term Evolution (LTE) Cell specific Reference Signal (CRS) and channel estimation. We demonstrated an energy autonomous ambient backscatter device (BD) and a real-time AmBC reader. This paper's results indicates that AmBC can reach the bit error rate (BER) to 10^-3 order of magnitude in practice. The proposed AmBC system is a promising candidate of AIoT solution.
