1. A data transmission method, comprising:

  • generating a data packet of a preset format according to n data units and attribute information of each data unit, wherein the attribute information comprises transmission channel information and a data length of the each data unit, n≥

    2; and

    transmitting the data packet to a receiving end, wherein the data packet comprises header information and the n data units, and at least one piece of the header information is generated according to same information in attribute information of at least two of the data units;

    wherein the data packet comprises i data unit sets, each data unit set comprises j data unit subsets, each data unit subset comprises one piece of header information and s data units corresponding to the header information, wherein attribute information of the data units in a same data unit subset is the same, attribute information of data units in different data unit subsets is partially the same, and a sum of all data unit quantities s is n;

    i≥

    1, j≥

    2, s≥

    1;

    wherein one of i pieces of header information comprised in each data unit set comprises a first identifier, the transmission channel information, data length information and a data unit quantity s, and each of the rest pieces of the header information comprised in the each data unit set comprises a second identifier and difference information, wherein the data length information is a data length of one of the data units or a total data length of the s data units;

    the first identifier in the header information is used to indicate that the header information comprises the transmission channel information, the data length information and the data unit quantity s;

    the second identifier in the header information is used to indicate that the header information comprises the difference information;

    wherein the difference information is determined according to different information in data unit quantities s and attribute information of data units in different data unit subsets in a same data unit set.
