1. A method of coordination multi-point transmission, suitable for performing communication between at least one access point on a vehicle and a plurality of base stations, the method comprising:
obtaining a first coordination multi-point set corresponding to a first position of the vehicle by looking up a database according to the first position, wherein the first coordination multi-point set is a set of a plurality of first coordinated base stations among the plurality of base stations; and
obtaining a first beamforming weighted matrix correspondingly using by each of the first coordinated base stations by looking up the database,
wherein each of the first coordinated base stations performs a coordination multi-point transmission with the at least one access point on the vehicle by using the corresponding first beamforming weighted matrix of the each of the first coordinated base stations.
