1. A data transmission method, comprising:
determining an aggregated physical layer protocol data unit (A-PPDU), wherein the A-PPDU comprises at least two physical layer protocol data units (PPDUs) belonging to different protocols, the A-PPDU comprises a first sequence including N segments of subsequences, any of the N segments of subsequences is obtained by performing phase rotation on a high efficiency-long training field (HE LTF) sequence and/or an extreme high throughput-long training field (EHT LTF) sequence based on a phase rotation parameter corresponding to the HE LTF sequence and/or a phase rotation parameter corresponding to the EHT LTF sequence, N phase rotation parameters corresponding to the N segments of subsequences comprise at least one phase rotation parameter whose value is −1, and N is an integer greater than or equal to 2; and
sending the A-PPDU.
