1. A data transmission method applied in a network device, comprising:
obtaining an initial transmission time of a Frequency Domain-Aggregated-Physical layer Protocol Data Unit (FD-A-PPDU) comprising at least two Multi-User (MU) PPDUs;
obtaining an initial number of A-PPDU padding symbols for each of the at least two MU PPDUs;
determining a first transmission time of the FD-A-PPDU and a first number of A-PPDU padding symbols for each of the at least two MU PPDUs based on the initial transmission time of the FD-A-PPDU and the initial number of A-PPDU padding symbols for each of the at least two MU PPDUs;
generating the FD-A-PPDU based on the first transmission time of the FD-A-PPDU and the first number of A-PPDU padding symbols for each of the at least two MU PPDUs; and
transmitting the generated FD-A-PPDU to a plurality of terminal devices.
