Title:
DATA TRANSMISSION METHOD AND APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/087824
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and relates to a data transmission method and apparatus, and a storage medium. The method comprises: a base station sends a MAC signaling to a terminal; the base station sends DCI to the terminal; the terminal determines target beam indication information corresponding to a target antenna panel in m antenna panels according to a first beam indication codeword and mapping information; the terminal determines, according to the target beam indication information, a corresponding target beam when using the target antenna panel for transmitting data. In the technical solution provided by embodiments of the present application, in a multi-antenna panel scenario, a terminal can select a correct beam to transmit data for different antenna panels, thereby improving the data transmission success rate in the multi-antenna panel scenario. In addition, the technical solution provided by the embodiments of the present application can implement data transmission between a terminal and a base station by using multiple beams at the same time, and improve the communication robustness.
