1. A method for wireless communication performed by a base station (BS), the method comprising:
rate matching, based on a rate matching pattern indicating a plurality of reserved resource elements, a downlink (DL) communication channel, wherein the DL communication channel is associated with a first radio access technology (RAT);
transmitting, to a user equipment (UE) on one or more antenna ports, a DL communication in the rate matched DL communication channel; and
transmitting, on the one or more antenna ports, one or more reference signals in the plurality of reserved resource elements, wherein the one or more reference signals are associated with a second RAT different from the first RAT, and wherein the transmitting the DL communication and the transmitting the one or more reference signals are based on a same transmit configuration.
