1. A method for determining an antenna port of a reference signal at a terminal side device or a network side device, comprising:

  • determining a smallest number of a control channel element mapped to a downlink control channel; and

    determining, according to a corresponding relationship between smallest numbers of control channel elements and antenna ports of the reference signal, the antenna port of the reference signal corresponding to the smallest number of the control channel element mapped to the downlink control channel, wherein the corresponding relationship indicates that at least two smallest numbers of control channel elements mapped to at least two downlink control channels correspond to one of the antenna ports of the reference signal;

    determining, according to a corresponding relationship between the smallest number of the control channel element mapped to the downlink control channel and an initialization parameter of a quasi-random sequence, the initialization parameter of the quasi-random sequence; and

    determining, according to the initialization parameter of the quasi-random sequence, the reference signal to be transmitted over the determined antenna port of the reference signal between the terminal side device and the network side device.
