Abstract

A satellite communication system includes a satellite, a satellite base station, and a user device. The satellite supports a number of satellite beams. Each satellite beam includes a number of cells. The satellite base station can communicate with the satellite via a feeder link. The user device is in communication with the satellite and the satellite base station. The user device can select a cell that covers a location of the user device based on a cell contour and a quality of a downlink signal received from the satellite base station. The satellite communication system can be operated by using LTE and/or NB-IoT standards, protocols, and/or waveforms.
