TL;DR: In this article, an energy harvesting-based dynamic spectrum allocation method of D2D communication under a cellular network is proposed, which includes the following steps that: various parameters of a communication system under the cellular network are set.

TL;DR: In this article, the authors proposed an energy-efficient resource distribution and interference alignment combined method in a heterogeneous network, which is based on the lowest rate demand of a macrocell user, the signal intensity of a femto-cell user and the interference intensity of the femtocell user.

TL;DR: In this paper, the authors proposed a power and time joint allocation method in a D2D wireless power supply communication network, which includes the following steps: step 1, constructing a wireless powersupply communication network; step 2, calculating the energy absorbed by a DF transmission node, a signal to interference and noise ratio of a DF receiving node, and an achievable data transmission rate of DF users.

TL;DR: In this paper, the authors proposed an interrupt processing method based on beam selection and base station switching in a high-frequency heterogeneous network, where a user selects a closest small cell base station as the current service base station, determining an adjacent base station set of the current SBS as the optional standby base station according to the nearest principle, and performing beam training on the user and the SBS to determine the current beam pair and a standby beam pair set.
