Abstract
Apparatuses and methods for transmission and reception without precise timing capability. A method for an Internet of Things (IoT) device to communicate with a reader includes receiving a physical reader-to-device channel (PRDCH) from the reader and determining a transmission timing of a physical device-to-reader channel (PDRCH) to the reader. Transmission of the PDRCH is triggered by reception of the PRDCH. The transmission timing of the PDRCH is determined based on a reception timing of the PRDCH or another PRDCH. The method further includes transmitting the PDRCH to the reader at the determined transmission timing. The PDRCH is On-Off Keying (OOK) or Phase-Shift Keying (PSK) modulated by backscattering an externally provided carrier wave (CW) or generating the CW internally.
