1. A method of wireless communication by a user equipment (UE), the method comprising:
receiving, from a base station, a report configuration message triggering a channel state feedback procedure, the UE and the base station operating in a multiple transmission and reception point (multiple-TRP) communication mode, wherein the report configuration message requests a multiple-TRP transmission value that includes at least one of a quantity of layer indicator (LI) values and a strongest TRP indicator (STI) value;
generating channel state information (CSI) information based on the receiving of the report configuration message, the CSI information including selected multiple-TRP transmission values based in part on the report configuration message and on at least one of available uplink resources or propagation loss; and
transmitting, to the base station, a report including the generated CSI information.
