1. A method for processing a downlink pilot signal, the method comprising:

  • detecting, by a receiving end, downlink measurement pilot ports to obtain a received signal corresponding to each downlink measurement pilot port on each receiving antenna;

    performing screening on the downlink measurement pilot ports according to the received signals;

    calculating a receiving weight vector of each downlink measurement pilot port, and using an uplink precoding weight vector, calculated and obtained by combining the receiving weight vector with uplink and downlink operating frequencies, for data precoding;

    or, using N uplink precoding weight vectors, calculated and obtained by combining the receiving weight vector with uplink and downlink operating frequencies, for uplink pilot precoding, where N is the number of uplink precoding pilots transmitted, and N is an integer which is greater than or equal to 1.
