Abstract
A system and method of operating an Internet of Things (IOT) device and an IOT manager device. The method includes determining, during operation of the IOT device in a low power mode, an orthogonal time frequency space (OTFS) transmission waveform using two-dimensional (2D) channel state information relevant to a delay-Doppler channel domain. The method further includes transmitting, during operation of the IOT device in a high power mode, the OTFS transmission waveform. The process of determining the OTFS transmission waveform may include, for example, receiving, from the IOT manager device, the 2D channel state information and storing it within a memory of the IOT device. Alternatively, at least one OTFS pilot transmission may be received from the IOT manager device and the 2D channel state information determined using the OTFS pilot transmission.
