The embodiment of the present application provides a method for transmitting a detection reference signal, a network device and a terminal device to avoid frequent carrier switching due to the need to reduce carrier switching overhead. The method includes: a network device sends an indication message to the terminal device for indicating that the terminal device sends SRS on the second symbol in the first symbol, the first symbol is the symbol of the upstream link pilot slot UpPTS portion of two special subframes in the wireless frame, and the second symbol is the UpPTS portion of at least one special subframe in the two special subframes. On the second symbol, the network device receives the SRS sent by the terminal device.
