Abstract: In at least some embodiments, a channel resource scheduling method includes sending a management frame that includes directional channel quality measurement information. The directional channel quality measurement information includes identifiers of at least two candidate station pairs selected by the access point to perform channel quality measurement and a channel resource that is used for directional channel quality measurement and that is allocated to each candidate station pair in the at least two candidate station pairs. A directional channel quality measurement report returned by each candidate station in the at least two candidate station pairs is received. At least two target station pairs to perform spatial sharing are selected based on the directional channel quality measurement report of each candidate station. In at least some embodiments, the directional channel quality measurement information can be carried in the management frame to save the channel resource and improve system efficiency.
