A method of coordination multi-point transmission is provided, which let a plurality of base stations perform communication with at least one access point of a vehicle. A first coordination multi-point set corresponding to a first position of the vehicle is obtained by looking up a database according to the first position. The first coordination multi-point set is a set of a plurality of first coordinated base stations among the plurality of base stations. A first beamforming weighted matrix correspondingly using by each of the plurality of first coordinated base stations is obtained by looking up the database. A coordination multi-point transmission is performed with the at least one access point of the vehicle by the each of the plurality of first coordinated base stations using the corresponding first beamforming weighted matrix of the each of the plurality of first coordinated base stations.
