AI Technical Summary

Technical Problem

Existing radio frequency energy harvesting solutions are inefficient and cannot meet the daily usage needs of IoT devices. Furthermore, wireless energy transmission and data transmission are difficult to coexist, affecting the quality of data transmission.

Method used

OFDM symbols are used to allocate different subcarriers for wireless power transmission and data transmission. The power subcarriers and data subcarriers do not overlap in the frequency domain. Through predefined or preprocessed symbol design, different power amplifiers are used to amplify the signals, ensuring the coexistence of wireless power transmission and data transmission.

Benefits of technology

It enables the coexistence of wireless power transmission and data transmission, reduces the impact of wireless power transmission on data transmission, and improves power transmission efficiency and data transmission quality.

Abstract

The application relates to the field of mobile communication, and can be applied to a protocol framework such as NR or 6G, in particular to a signal processing method and device and a readable storage medium, the method comprising: obtaining and sending one or more OFDM symbols, the one or more OFDM symbols being carried on the same resource block, the same resource block containing N subcarriers, the N subcarriers including M energy charging subcarriers and K data subcarriers, and the intersection of the M energy charging subcarriers and the K data subcarriers being an empty set, wherein the energy charging subcarriers carry energy charging symbols, and the data subcarriers carry data symbols. According to the embodiment of the application, the coexistence of wireless energy transmission and data transmission can be realized, and the influence of wireless energy transmission on data transmission is reduced.
