1. A method of decoding a downlink by a user equipment (UE), the method comprising:
transmitting, by the UE, to a base station, an indication that the UE supports partial transmission of a reference signal;
determining, by the UE, whether the downlink received from the base station is rate matched; and
in response to determining that the downlink is rate-matched, determining, by the UE, that a rate matching pattern of the downlink is applicable for the partial transmission of the reference signal, and decoding, by the UE, the downlink with the partial transmission of the reference signal,
wherein determining that the rate-matching pattern of the downlink is applicable for the partial transmission of the reference signal is based on a characteristic of the downlink,
wherein the characteristic of the downlink includes processing time, and
wherein the processing time includes a normal processing time and a fast processing time corresponding to the indication.
