Wireless communication method and related apparatus

A method for receiving a trigger frame in a wireless local area network, comprising:

• receiving, by a station, a trigger frame only on a frequency segment on which a sensed 20 MHz is located;
• and
• determining, based on the trigger frame, whether the station is scheduled.

A communications apparatus, wherein the communications apparatus comprises one or more modules, and is configured to perform the following steps:

• generating a physical layer protocol data unit PPDU, wherein the PPDU comprises one or more trigger frames, each trigger frame corresponds to one frequency segment, and each trigger frame is used to schedule at least one or more stations parking on the corresponding frequency segment;
• and
• sending the one or more trigger frames in the PPDU, wherein each trigger frame is carried in the corresponding frequency segment.
