TL;DR: In this article, the authors proposed a communication method, a base station, and a terminal device, which includes: transmitting signals to a terminal devices by using n port groups, where each of the n ports includes at least two ports; and receiving, by the. TL;DR: In this article, the authors proposed a communication method, a base station, and a terminal device, which includes: transmitting signals to a terminal devices by using n port groups, where each of the n ports includes at least two ports; and receiving, by the. In order to solve this problem, this study proposes a flexible communication mechanism based on the device-to-device (D2D) technique for the intelligent terminals to deal with the processing pressure of massive information in the network. This proposed mecha-nism introduces where and how to use the. The present disclosure relates to a base station, a terminal, and a communication method. Currently, the Third Generation Partnership Project (3GPP) is conducting a technical study and standardization of Long Term Evolution (LTE)-Advanced Pro. By exploring the overlap between base station distribution and electric vehicle charging infrastruc-ture, we demonstrate the feasibility of efficiently charging EVs using base station batteries and renewable power plants at the Hub. Our model considers various factors, including base station.
