Provided are a method for transmitting signals and corresponding terminals, and base stations, where the method for transmitting signals is performed by a terminal in a communication system. The method includes determining, whether to transmit an additional reference signal to a base station in the communication system according to information on channel conditions of the terminal; transmitting a main reference signal to the base station, where the main reference signal is used for channel estimation between the terminal and the base station; and when determining to transmit an additional reference signal to the base station, transmitting an additional reference signal to the base station according to configuration information of the additional reference signal.
