Abstract: A method includes: determining, by an AP from all STAs associated with the AP, a concurrent STA joining a concurrent group, and generating concurrent group information of the concurrent group; and sending the concurrent group information to another AP in a system other than the AP, so that a BSS to which the another AP belongs determines, according to the concurrent group information, to join the concurrent group, to eventually form the concurrent group. All concurrent STAs that are associated with the AP and that join the concurrent group perform channel contention within a concurrent time by using an increased target CCA threshold, to increase a possibility that the concurrent STAs send data, so that a system throughput is improved.
