METHOD AND APPARATUS FOR CHANNEL ACCESS IN ENERGY HARVEST-BASED COMMUNICATION SYSTEM

Abstract

A method of a device may comprise: receiving, from a reader, a first subframe including information on channel access resources for harvesting rate stages; determining a channel access resource according to a harvesting rate of the device, based on the information on the channel access resources; receiving a carrier wave from the reader; generating a backscattered signal including a second subframe by reflecting the carrier wave; and transmitting the backscattered signal to the reader by using the channel access resource.
