Abstract
The method includes: an intercepting station detecting a first radio signal of a third-party station and updating a local network allocation vector and/or response indication deferral; triggering a channel contention access procedure when determining that a second radio signal of the third-party station meets a spatial orthogonal condition, and then completing data transmission within updated time. In the case that the network allocation vector or response indication deferral is not 0, the third-party station ignoring or resetting the network allocation vector or the response indication deferral when determining that a sector transmission in a transmission initiated by the station is orthogonal with a transmission space to be carried out by itself, the third-party station initiating a contention and starting the spatial orthogonal transmission within a duration indicated by the updated network allocation vector or the response indication deferral.
