Control method and control device in heterogeneous three-dimensional hierarchical network, and communication system

A control method that is in a heterogeneous three-dimensional hierarchical network and for a terminal, wherein the heterogeneous three-dimensional hierarchical network comprises a ground mobile communication sub-network and a non-ground mobile communication sub-network, and the control method comprises:

• obtaining an operating mode and/or an operating bandwidth of a cell where the terminal is located;
• and
• obtaining an operating mode of the terminal and/or a sub-network where the terminal is located in accordance with the operating mode and/or the operating bandwidth of the cell where the terminal is located,
• wherein the ground mobile communication sub-network and the non-ground mobile communication sub-network use a same or unified radio access technology;
• wherein the control method further comprises:
• when the operating mode of the terminal is a standalone operating mode, performing control and/or data transmission on a corresponding sub-network;
• or
• when the operating mode of the terminal is an intra-layer carrier aggregation mode, performing data transmission at a first rate, access, synchronization, and/or control on a main carrier, and performing data transmission at a second rate on an auxiliary carrier corresponding to the main carrier, the first rate being smaller than the second rate;
• or
• when the operating mode of the terminal is a cross-layer carrier aggregation mode, performing data transmission at the first rate, access, synchronization, and/or control on a sub-network where the main carrier is located, and performing data transmission at the second rate on a sub-network where the auxiliary carrier corresponding to the main carrier is located, the first rate being smaller than the second rate.
