FIELD: communication.
SUBSTANCE: method of signal transmission includes transmitting to the terminal apparatus via the network apparatus the transformation correlation between a sounding reference signal (SRS) resource group and a downlink reference signal via radio resource control (RRC) signaling information, wherein the transformation correlation is further comprised of a state identifier, and transmission of the indicating information by the network apparatus to the terminal apparatus. A state identifier is used therein to identify the transformation correlation between the SRS resource group and the downlink reference signal.
EFFECT: improved transmission efficiency of a communication system.
