Abstract

The present application relates to a NB‑IoT wireless energy distribution method, device, computer equipment and storage medium. The method includes: constructing a spectrum efficiency model of the NB-IoT system according to the acquired characteristic information of the NB-IoT system; establishing a corresponding total efficiency optimization model according to the spectrum efficiency model; The maximum efficiency is used as the objective function, and the constraints include: the interference index between the NB‑IoT system and the LTE system sharing the carrier and the maximum spectrum efficiency index corresponding to the downlink modulation mode of the NB‑IoT system; the total efficiency optimization model is solved, when the When the maximum value of the objective function is obtained, the value of the parameter variable in the total efficiency optimization model is obtained to determine the optimal wireless energy allocation strategy. By adopting this method, the optimal resource allocation scheme can be obtained by establishing a wireless energy transmission model combined with NB-IoT, and analyzing the power allocation strategy in wireless communication according to the model, ensuring that the NB-IoT system terminal has a stable and reliable Energy source, 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...
