Data transmission method and device based on uplink grant-free scheduling, and storage medium

A data transmission method based on uplink grant-free scheduling, implementable by a terminal, and comprising:

• acquiring a total data volume, the total data volume being a data volume of data to be transmitted in the terminal before transmitting first uplink data;
• and
• determining pre-configured first uplink scheduling information from at least two pieces of pre-configured uplink scheduling information based on the total data volume;
• or determining a physical resource configuration for transmitting the first uplink data from at least two physical resource configurations in the first uplink scheduling information;
• transmitting the first uplink data to a base station based on the first uplink scheduling information;
• transmitting first indicating information of data to be transmitted to the base station, the first indicating information of data to be transmitted for indicating whether there is data to be transmitted in the terminal after transmitting the first uplink data;
• and
• transmitting second uplink data to the base station on a target resource based on second uplink scheduling information in response that there is the data to be transmitted in the terminal, the second uplink data being all or part of the data to be transmitted, and the target resource is a resource reserved by the base station for the terminal based on the second uplink scheduling information.

A data transmission method based on uplink grant-free scheduling, implementable by a base station, and comprising:

• receiving first uplink data transmitted by a terminal based on pre-configured first uplink scheduling information, wherein the first uplink scheduling information is obtained by:
• acquiring, by the terminal, a total data volume, the total data volume being a data volume of data to be transmitted in the terminal before transmitting the first uplink data;
• and determining, by the terminal, the first uplink scheduling information from at least two pieces of pre-configured uplink scheduling information based on the total data volume, wherein each piece of pre-configured uplink scheduling information has a corresponding threshold;
• or determining a physical resource configuration for transmitting the first uplink data from at least two physical resource configurations in the first uplink scheduling information, wherein each physical resource configuration has a corresponding threshold;
• acquiring first indicating information of data to be transmitted from the terminal, the first indicating information of data to be transmitted for indicating whether there is data to be transmitted in the terminal after transmitting the first uplink data;
• reserving a target resource for the terminal based on second uplink scheduling information in response to the first indicating information of data to be transmitted indicating that there is the data to be transmitted in the terminal;
• and
• receiving, on the target resource, second uplink data transmitted by the terminal based on the second uplink scheduling information, the second uplink data being all or part of the data to be transmitted.
