摘要: A cooperative transmission system and a cooperative transmission method used in multiple access points in a wireless local network are provided. The cooperative transmission system includes a plurality of access points, a clustering controller and at least one cluster controller. Each of the access points serves at least one user device within a serving range of the access point. The clustering controller clusters the access points into a plurality of clusters according to locations of the access points and the serving range. The at least one cluster controller controls cooperative synchronous downlink transmissions among all the access points within a cluster governed by the cluster controller, and the clusters, when intersecting with one another, employ an interference suppression mechanism to eliminate interference generated by the user devices or neighboring access points located in different clusters. Through the use of the cooperative communication technique and the interference suppression mechanism, the interference generated by a plurality of access points in a wireless local network due to overlapped basic service sets is avoided.
