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.

Method of coordination multi point transmission, control node and wireless communication device

A multiple input multiple output (MIMO) antenna system, a signal transmission method, a signal transmission apparatus and a computer program product for the MIMO antenna system are provided. The signal transmission method comprises the following steps of transmitting a signal with a first signal transmission mode and a first transmission power via a signal transmission channel; receiving a signal to noise ratio (SNR) of the signal; receiving an interference value of the signal transmission channel; obtaining a power weight value according to the interference value; determining a system threshold of the signal transmission channel to the SNR of the signal; determining a second signal transmission mode of the signal transmission channel based on the system threshold; and determining a second transmission power of the signal transmission channel according to the power weight value.
