A signal transmission method and an associated device. The method comprises: a first network device receives signals of M antenna ports sent by a second network device, where M is a positive integer; the first network device feeds back first information of N antenna ports in the M antenna ports according to a first rule, where N is an integer smaller than or equal to M, and the first rule is at least one of antenna associated information, SNR, channel capacity, throughput, an SU (single-user)/MU (multi-user) transmission manner, a transmission mode, codebook information and a data packet size. The present invention performs the optimum antenna configuration according to at least one of antenna associated information, SNR, channel capacity, throughput, an SU/MU transmission manner, a transmission mode, codebook information or a data packet size and carries out more effective antenna selection. |
