1. A data transmission method, comprising:
receiving, by a terminal, a first uplink grant from a network device;
sending, by the terminal, first uplink data in to-be-sent data to the network device by using the first uplink grant;
receiving, by the terminal, a second uplink grant from the network device; and
sending, by the terminal, second uplink data to the network device by using the second uplink grant, wherein the second uplink data is at least a part of uplink data in the to-be-sent data except the first uplink data;
wherein the terminal is in a first state, and the first state comprises an idle state or an inactive state; and
wherein the sending the first uplink data in the to-be-sent data to the network device comprises sending the first uplink data to the network device in response to the terminal determining that a preset condition is met, wherein the terminal determining that the preset condition is met comprises the terminal performing one or more of the following:
the terminal determining that the to-be-sent data exists;
the terminal determining that a data volume of the to-be-sent data is less than or equal to a preset threshold;
the terminal receiving fifth indication information from the network device, wherein the fifth indication information is used to indicate the terminal to send the to-be-sent data to the network device; or
the terminal determining that the to-be-sent data is a service data unit (SDU).
