1. A resource unit indication method, wherein the method comprises:
receiving, by a station, a trigger frame from an access point, wherein the trigger frame comprises a resource unit allocation subfield that indicates a resource allocated to the station, the resource unit allocation subfield comprises a resource unit indication of 7 bits and a primary/secondary indication of 2 bits, the 2 bits indicate a location of a 80 MHz, and the 7 bits indicate a location of a resource unit (RU)/multiple resource unit (MRU) in the 80 MHZ, wherein
the primary/secondary indication of the 2 bits indicates one of the following situations: 00 indicates primary 80 MHz (P80 MHz), 01 indicates secondary 80 MHz (S80 MHz), 10 indicates lower 80 MHz in secondary 160 MHz (S160 MHz), and 11 indicates higher 80 MHz in the secondary 160 MHz (S160 MHz);
determining, by the station, an absolute frequency corresponding to the primary/secondary indication of the 2 bits; and
determining, by the station based on the absolute frequency and a value of the 7 bits, the RU/MRU allocated to the station.
