Information instruction method and communication device

Abstract

This application relates, for example, to the field of wireless fidelity technology, and more particularly to information indicating methods. [Solution] The method includes an access point (AP) determining and transmitting resource instruction information. The resource instruction information includes a plurality of bit sequences. A first bit sequence in the plurality of bit sequences corresponds to a first resource unit. The first resource unit is a resource unit in a resource block set assigned to a first station (STA) or a plurality of STAs. The resource block set includes at least two resource units. In the method provided in embodiments of this application, two content channels are used to transmit HE-SIG B to indicate that a plurality of resource units are assigned to one or more stations in order to reduce signaling overhead.
