A data transmission processing method in a wireless local area network, WLAN, comprising: reserving, by a first station, a time-frequency resource occupied for data communication between the first station and a second station, wherein the first station is an access point of the WLAN and the second station is an associated station of the first station; establishing a neighbor list, wherein the neighbor list includes an access point, AP, and a station, STA, that can be sensed by the first station; acquiring at the first station, a neighbor list of the second station, where the neighbor list of the second stations includes neighboring stations of the second station; selecting a third station based on the neighbor list of the first station and the neighbor list of the second station wherein the selected third station is not a neighboring station of the second station and the selected third station is a non-associated neighboring station of the first station, such as a neighboring access point, AP, or a neighboring station, STA; allocating, by the first station, at least a partial time-frequency resource of the time-frequency resource to the third station, so that the third station performs data transmission on the allocated time-frequency resource, the third station is a non-associated neighboring station of the first station, such as a neighboring access point, AP, or a neighboring station, STA, wherein the step of allocating, by the first station, at least a partial time-frequency resource of the time-frequency resource to a third station comprises: sending, by the first station, scheduling signaling to the third station, wherein the scheduling signaling comprises information indicative of the allocation. reserving, by a first station, a time-frequency resource occupied for data communication between the first station and a second station, wherein the first station is an access point of the WLAN and the second station is an associated station of the first station; establishing a neighbor list, wherein the neighbor list includes an access point, AP, and a station, STA, that can be sensed by the first station; acquiring at the first station, a neighbor list of the second station, where the neighbor list of the second stations includes neighboring stations of the second station; selecting a third station based on the neighbor list of the first station and the neighbor list of the second station wherein the selected third station is not a neighboring station of the second station and the selected third station is a non-associated neighboring station of the first station, such as a neighboring access point, AP, or a neighboring station, STA; allocating, by the first station, at least a partial time-frequency resource of the time-frequency resource to the third station, so that the third station performs data transmission on the allocated time-frequency resource, the third station is a non-associated neighboring station of the first station, such as a neighboring access point, AP, or a neighboring station, STA, wherein the step of allocating, by the first station, at least a partial time-frequency resource of the time-frequency resource to a third station comprises: sending, by the first station, scheduling signaling to the third station, wherein the scheduling signaling comprises information indicative of the allocation.
