An uplink data transmission method includes: a first terminal transmits the uplink data of a first service type over a first uplink resource; the first terminal receives a scheduling indication transmitted by a network device, wherein the scheduling indication comprises the starting position and the scheduling period of semi-persistent scheduling; before the starting position, the first terminal stops transmitting the uplink data of the first service type; after the starting position, the first terminal transmits the uplink data of the first service type again according to the scheduling period. The first terminal determines the starting position of scheduling and the scheduling period according to the scheduling indication, and stops transmitting and performs transmission again according to the starting position.
