Abstract

The invention discloses a NB-IoT wireless energy distribution method and device, computer equipment and a storage medium The method comprises the following steps: according to acquired characteristicinformation of a NB-IoT system, constructing a spectrum efficiency model of the NB-IoT system; according to the spectrum efficiency model, establishing a corresponding total efficiency optimization model; enabling the total efficiency optimization model to take maximum spectral efficiency of multiple NB-IoT terminals as an objective function, wherein the constraint includes: an interference indicator between the NB-IoT system and the LTE system sharing the carrier, and a maximum spectrum efficiency indicator corresponding to the downlink modulation mode of the NB-IoT system; solving the totalefficiency optimization model, when the maximum value of the objective function is obtained, acquiring the value of the parameter variable in the total efficiency optimization model and determining awireless energy optimal allocation strategy. By adopting the method, a wireless energy transfer model combined with NB-IoT can be established, and the power allocation strategy in wireless communication is analyzed according to the model, and an optimal resource allocation scheme is obtained, thereby ensuring that the NB-IoT system terminals have stable and reliable energy sources and high utilization rate.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to a NB-IoT wireless energy distribution method, device, computer equipment and storage medium. Background technique [0002] The Internet of Things (IoT) is an information carrier such as the Internet and traditional telecommunication networks, which enables all ordinary objects that can perform independent functions to realize interconnection and intercommunication. Narrow Band Internet of Things (NB-IoT) is an important branch of the Internet of Everything. NB-IoT is built on a cellular network and only consumes 180KHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrades. [0003] Most IoT devices are powered by batteries. The battery life limits the application scenarios of the system and the life cycle of the terminal, and the low energy utilization rate also violates the...
