Abstract: A data retransmission method and device are provided to resolve a problem of lacking in a retransmission scheme supporting retransmission via different connections in the prior art. In one embodiment of the invention, the method comprises: upon determining that a transmission node corresponding to a terminal satisfies a multi-transmission node retransmission criterion, selecting, by a target protocol layer in a transmitting device and responsible for managing transmission via multiple transmission nodes, and for a retransmission data packet corresponding to the terminal, at least one transmission node; and performing, via the selected transmission node, data packet retransmission. The embodiment is employed to select, upon determining that a transmission node corresponding to a terminal satisfies the multi-transmission node retransmission criterion, and for a retransmission data packet corresponding to the terminal, at least one transmission node, thereby implementing retransmission via different connects, further increasing reliability and throughput of transmission in a system.

Abstract: Disclosed in the present application are an uplink control channel transmission method, a terminal, a base station and a device, for solving the problem, in the prior art, that no relevant solution addresses how to perform long NR-PUCCH transmission in multiple slots. The method applied to a terminal comprises: determining a total transmission length T of an uplink control channel (PUCCH) to be transmitted in P slots; determining the transmission structure of the PUCCH on the basis of T; and transmitting the PUCCH in the P slots according to the transmission structure. The present invention defines the transmission structure for long PUCCH transmission in multiple slots, realizing the normal transmission of the long PUCCH in multiple slots.
