1. A data transmission method, comprising:
generating a signaling field of a physical layer protocol data unit (PPDU), wherein:
a channel bandwidth for transmitting the PPDU includes at least two frequency segments that include a first frequency segment, wherein:
the channel bandwidth includes a resource unit (RU) for multi-user multiple input multiple output (MU-MIMO) transmission;
allocating the RU to a plurality of stations;
parking, a first station from the plurality of stations, on the first frequency segment;
leaving unparked a second station from the plurality of stations from the first frequency segment;
wherein:
the signaling field includes a common field and a user specific field;
the user specific field includes a user field corresponding to the RU;
the user field corresponding to the RU is a user field of the first station; and
the common field includes a resource unit allocation subfield corresponding to the RU that indicates the RU and a quantity of user fields corresponding to the RU; and
sending the signaling field on the first frequency segment.
