1. A method of wireless communication at a base station, comprising:
receiving information regarding a beam calibration mode from a User Equipment (UE), the information comprises an indication of a need to perform calibration for full duplex communication;
determining a set of silent symbols for beam calibration measurements by the UE for full duplex communication from a pool comprising a plurality of sequences of silent symbols, wherein the determined set of silent symbols includes fewer silent symbols than the plurality of sequences of silent symbols;
transmitting, to the UE, an indication of the set of silent symbols for the beam calibration measurements by the UE, wherein the transmitting the indication of the set of silent symbols comprises transmitting based on the receiving the information;
configuring the UE with a transmission power for the beam calibration measurements for the full duplex communication during the set of silent symbols; and
refraining from transmitting during the set of silent symbols,
with the set of silent symbols comprising at least one silent symbol,
wherein the UE is trained with a first set of the set of silent symbols and calibrated with a second set of the set of silent symbols.
