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.

Abstract: Disclosed are a method and device for data exchanging, and relates to communication technology. The embodiments of the present application includes: pre-allocating virtual resource to user terminals, and activating the virtual resource in case of need, so user terminals can use the pre-allocated resource to exchange data with network side. When inactive, the virtual resource can allocated to other users. For small data, irregular service, pre-allocation of virtual resource and activating it in case of need, can improve efficiency of use of resource. Meanwhile, dividing users into groups and scheduling by groups can reduce control overhead.

Abstract: An uplink scheduling-free transmission method and an uplink scheduling-free transmission device are provided. The uplink scheduling-free transmission method includes: dividing, by a base station, MA resources into groups of MA resources, and configuring, by the base station, the groups of MA resources to obtain at least two groups of MA resource pools, wherein at least parts of respective MA resources in the at least two groups of MA resource pools are different from each other; and notifying, by the base station, a UE of the at least two groups of MA resource pools, to enable the UE to select an MA resource pool from the at least two groups of MA resource pools, wherein the selected MA resource pool is to be used by the UE.

Abstract: A method and a device for determining multi-user transmission mode are provided. The method includes: grouping terminals based on channel spatial characteristics of the terminals; allocating data transmission modes to the terminals, where data transmission of the terminals in different groups is performed on an identical scheduling time-frequency resource and in a Multi-User Multiple-Input Multiple-Output (MU-MIMO) mode, and data transmission of the terminals in an identical group is performed on the scheduling time-frequency resource and in a non-orthogonal multiple access mode.

Abstract: The present disclosure relates to the field of wireless communication technology, and provides a data transmission method and a data transmission device, so as to solve the problem in the related art where, for 5G application scenarios, in the case that an uplink scheduling algorithm for a conventional 4G system continues to be used, a large number of control signaling overheads are required due to the meteoric growth in the number of UEs to be connected. In the present disclosure, a network side device determines non-orthogonal multiple access basic transmission units allocated to UEs, detects a pilot signal from each UE on the corresponding non-orthogonal multiple access basic transmission unit, and in the case that the pilot signal has been detected, performs data detection on the UE which has transmitted the pilot signal through the non-orthogonal multiple access basic transmission unit.
