Claim 0:
1. A data transmission method based on uplink grant-free scheduling, comprising:
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 first uplink data; and
determining, by the terminal, 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, by the terminal, the first uplink data to a base station based on the first uplink scheduling information; transmitting, by the terminal, first indicating information of data to be transmitted to the base station, the 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;
receiving, by the base station, the first uplink data and the first indicating information of data to be transmitted based on the first uplink scheduling information;
reserving, by the base station, a target resource for the terminal based on second uplink scheduling information in response that there is the data to be transmitted in the terminal;
transmitting, by the terminal, second uplink data to the base station on the target resource based on the second uplink scheduling information, the second uplink data being all or part of the data to be transmitted; and
receiving, by the base station, the second uplink data on the target resource based on the second uplink scheduling information.
