Abstract

The invention provides a data transmission method and system based on a multi-antenna panel and a storage medium. The method comprises steps that a terminal sends antenna panel parameters to a base station; the base station allocates resources for uplink transmission of the antenna panel based on the antenna panel parameters; the terminal determines an optimal sending beam corresponding to the antenna panel, and sends first beam information corresponding to the optimal sending beam to the base station; the base station determines an optimal receiving beam corresponding to the antenna panel, and sends second beam information corresponding to the optimal receiving beam to the terminal; and the base station and the antenna panel respectively use the optimal sending beam and the optimal receiving beam to carry out data transmission. According to the method, the system and the storage medium disclosed by the invention, the transmission of the target reference signal resource or the resource set can be indicated by using the antenna panel parameters, and beam measurement and antenna panel selection can be performed, so the uplink transmission performance of a multi-antenna panel can be improved, and the uplink coverage can be improved.

Description

Technical field[0001]The present invention relates to the field of communication technologies, and more particularly to a data transmission method, system, and storage medium based on a multi-antenna panel.Background technique[0002]5G (fifth-generation mobile communication technology) communication system requires demand for oversized flow density, ultra-high transmission rate, lower transmission delay, and more reliable network performance. NR-MIMO technology is one of the key technologies of 5G most potential. 5G FR2 high-band network deployment, facing the equipment hardware to achieve a huge challenge of complex, high cost, and poor covering performance. Currently, the high-frequency NR-MIMO technology enhancement is being studied, where multi-antenna panel uplink transmission is one of the technical enhancement. In order to further enhance the terminal reception capability and uplink coverage, meet the capacity and coverage requirements of various deployment scenarios, and real...
