Problems solved by technology

[0005] However, when multiple beam directions are used for sending and receiving, if the terminal does not correctly obtain the receiving beam or sending beam corresponding to each data stream indicated by the base station, the data will fail to be received by the terminal or the base station, resulting in reduced throughput

Abstract

The invention relates to a data transmission method, device and system and a storage medium. The data transmission method includes the steps of determining and sending indication signaling, wherein the indication signaling is used for indicating a data flow combination, the data flow combination comprises a plurality of data flows, the plurality of data flows are divided into at least two data flow groups, and the data flow of each data flow group in the at least two data flow groups corresponds to one beam direction; and receiving the indication signaling, determining a beam for transmittingeach data stream in the data stream combination according to the data stream combination indicated by the indication signaling, and transmitting each data stream in the data stream combination by using the beam. According to the invention, the accuracy of data stream transmission can be improved, and the throughput is improved

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular, to a data transmission method, device, system and storage medium. Background technique [0002] In a new wireless technology (New Radio, NR), in order to ensure coverage and resist path loss, it is generally necessary to perform data transmission based on a beam (beam). [0003] During beam-based data transmission, a network device (such as a base station) indicates a Transmission Configuration Indication (TCI) status or spatial relation information (spatial relation information) through signaling, and then indicates a receiving beam or a transmitting beam of a terminal. Wherein, each TCI state or each spatial relationship information corresponds to a reference signal (Reference Signal, RS) identifier, and the RS can be a non-zero power channel state information reference signal (channel state information reference signal, CSI-RS) or It is a synchronization sign...
