Transmission methods, transmission devices, terminals and network nodes

Abstract

This invention provides a transmission method, transmission device, terminal, and network node. The transmission method includes: establishing connections with both a ground network node and a space communication node; receiving downlink information using a link connected to the space communication node; and transmitting uplink information using a link connected to the ground network node. Using this transmission method, uplink communication between the terminal and the network side passes through the ground network node, while downlink communication passes through the space communication node, thus solving the problem of limited uplink transmission power. Simultaneously, it allows more terminals to use the space communication node without replacing radio frequency devices, and therefore also addresses the issue of high system capability requirements in existing satellite communication technologies.
