The method includes: a receiving end receives a data packet from a transmitting end, where the data packet includes a media access control MAC protocol data unit PDU, and the MAC PDU includes multiple MAC subPDUs, each of which includes an MAC sub-header; where the MAC sub-header includes a first information field used for indicating whether a current MAC subPDU has a same format as a next adjacent MAC subPDU. The embodiments of the present application allow for incorporating a first information field into an existing MAC sub-header format, where the first information field may be used for dynamically indicating whether a current MAC subPDU has a same format as a next adjacent MAC subPDU, it is thus advantageous to improve data processing flexibility and efficiency at the receiving end. ## Claims ### Claim 1 A data transmission method, comprising: receiving, by a receiving end, a data packet from a transmitting end, wherein the data packet comprises a media access control (MAC) protocol data unit (PDU), and the MAC PDU comprises multiple MAC subPDUs, each of which comprises a MAC sub-header; wherein the MAC sub-header comprises a first information field used for indicating whether a current MAC subPDU has a same format as a next adjacent MAC subPDU; in the multiple MAC subPDUs, a MAC sub-header of a MAC subPDU without an L field indicating a length comprises a second information field and a logical channel identifier (LCID) field, wherein the second information field is used for indicating whether the LCID field is read at the receiving end. ### Claim 2 (depends on 1) The method according to claim 1, wherein the second information field is located in a second bit of the MAC sub-header. ### Claim 3 (depends on 1) The method according to claim 1, wherein the first information field is located in a first bit of the MAC sub-header. ### Claim 4 (depends on 1) The method according to claim 1, wherein in the multiple MAC subPDUs, a MAC subPDU with the L field has a bit length of 7 or 15 or 8 or 16 for the L field. ### Claim 5 (depends on 1) The method according to claim 1, wherein in the multiple MAC subPDUs, a MAC sub-header of a MAC subPDU with the L field has a format of the first information field/R field of extension bits/the LCID field/F field indicating a bit length format/the L field;
