On the Maximum Energy Transmission Rate in Ultra-Reliable and Low Latency SIET
Résumé
In this paper, the maximum energy rate that can be achieved by a given code designed for simultaneously transmitting information to an information receiver (IR) and energy to an energy harvester (EH) through the binary symmetric channel is studied. The energy transmission rate is measured at the EH that is not necessarily colocated with the IR. Moreover, the energy transmission rate is calculated taking into account a reliability constraint and a latency constraint. The reliability is expressed in terms of the energy shortage probability, whereas the the latency is expressed in terms of the duration of the communication in channel uses. The exact maximum of the energy rate is presented. Nonetheless, it is not given in closed-form. To remediate this, approximations of the ESP are explored using large deviations and Gaussian approximations. These approximations lead to close form bounds on the energy transmission rate.
