[0002] Currently, because IoT devices are typically small in size and cannot carry sufficient battery power, they usually operate with low power consumption and have very limited battery life.

[0003] In wireless power communication systems using the "harvest-then-transmit" wireless transmission protocol, devices first collect energy from the energy transmitter during the downlink wireless energy transmission phase, and then transmit the information wirelessly to the information receiver during the uplink wireless information transmission phase. Verification has shown that wireless power transmission technology based on the "harvest-then-transmit" protocol is highly suitable for continuously powering IoT devices. It not only saves significant manpower costs by eliminating the need for manual battery replacements for IoT devices, but also greatly benefits the continuous operation of IoT devices, ensuring the sustainable development of the IoT network. However, the energy collected by IoT devices after wireless transmission from the energy transmitter largely depends on the strength of the energy signal upon arrival. Simultaneously, the signal strength when IoT devices transmit information is also closely related to the device's lifespan. Therefore, common communication system transmission problems such as severe signal attenuation, multipath effects at the receiver, and poor channel link quality severely hinder the sustainable development of wireless power communication networks and even the entire IoT network.
