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 random access feedback method, a random access processing method, a base station and a terminal are provided. The random access feedback method includes: receiving a first message sent by a terminal in performing a random access, wherein the first message comprises a preamble field and a data field; detecting the preamble field and the data field of the first message to obtain a detection result of whether or not a preamble exists in the first message and/or whether or not data is successfully obtained in the first message; and feeding back the detection result to the terminal.

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.

Abstract: A signal detection method and a signal detection device are provided. The signal detection method includes steps of: performing channel estimation based on a signal received by each of antennae, to acquire a channel estimation matrix for transmitters multiplexing on identical time-frequency resources on each of the antennae; determining an equivalent Pattern Division Multiple Access (PDMA) channel estimation matrix for each of the antennae based on a PDMA encoding matrix, and acquiring an equivalent multi-antenna PDMA channel estimation matrix for all the antennae based on the equivalent PDMA channel estimation matrix for each of the antennae; performing a joint detection based on the equivalent multi-antenna PDMA channel estimation matrix, an equivalent multi-antenna received signal vector and a set of constellation points of the transmitters multiplexing on the identical time-frequency resources, to acquire Log Likelihood Ratios (LLRs) for the transmitters; and decoding the LLRs for the transmitters, to acquire multi-user information at transmitting end.
