Abstract: The present application provides a spatial layered transmission method and a spatial layered transmission device. The spatial layered transmission method includes steps of: dividing to-be-transmitted data into at least two layers of spatial data; determining a symbol rate for each layer of spatial data, to enable an error between SERs for the layers of spatial data to be smaller than a predetermined error threshold; and encoding each layer of spatial data in accordance with the determined symbol rate, and transmitting the encoded layer of spatial data.

Abstract: The present disclosure relates to the field of communication technology, and provides a data transmission method, a data reception and detection method, a base station and a UE on the basis of a non-orthogonal mode. Before the transmission of pieces of data on physical resources by the base station, a plurality of pieces of data is firstly mapped to the physical resources at an amount not greater than the number of the pieces of data, each piece of data in the plurality of pieces of data is mapped to at least one physical resource, and the number of the physical resources to which each piece of data is mapped is not completely the same. Then, the pieces of data on the physical resources are transmitted by the base station. According to the present disclosure, it is able to transmit more pieces of data through fewer physical resources, thereby to improve the data transmission capability for the communication system.

Abstract: A method and a device for configuring and determining a code superposition-based multiuser encoding mode are provided. The configuring method includes steps of: determining, by a network device, UEs by which an identical transmission resource is to be multiplexed; and configuring, by the network device, different columns in a preconfigured encoding matrix formed through multiuser code superposition for the UEs, so as to enable each UE to transmit data in accordance with an encoding mode corresponding to the column configured by the network device, at least two columns in the encoding matrix having different diversity orders.
