Method for transmitting physical layer protocol data unit and communication apparatus

A method for transmitting a physical layer protocol data unit, comprising:

• receiving, by a second device, a physical layer protocol data unit (PPDU) from a first device, wherein the PPDU comprises first information carried in a first subcarrier set, the first information comprises data information and pilot information, the first subcarrier set comprises at least one first resource unit (RU) and/or at least one first multi-resource unit (MRU), the data information is carried on a data subcarrier included in the at least one first RU and/or a data subcarrier included in the at least one first MRU, and the pilot information comprises first pilot information carried on a first pilot subcarrier included in the at least one first RU and/or a first pilot subcarrier included in the at least one first MRU;
• and
• parsing, by the second device, the PPDU.
