1. A method for wireless communication at a user equipment (UE), comprising:
receiving, from a base station, a control information configuration that indicates a quantity of bits that are to be included in a control information field that indicates one or two sounding reference signal resource sets with which a first uplink communication is to be associated;
receiving, from the base station, a first control information communication that includes the control information field and that schedules the first uplink communication for the UE;
determining, based at least in part on the first control information communication and the control information configuration, whether one or two sounding reference signal resource sets are associated with the first uplink communication;
transmitting the first uplink communication to the base station based at least in part on the determining;
wherein the determining further comprises determining, based at least in part on a first bit of the first control information communication, whether one or two sounding reference signal resource sets are associated with the first uplink communication, and wherein the control information field includes a set of bits that indicate a number of sounding reference signal resources for each sounding reference signal resource set associated with the first uplink communication; and
wherein the set of bits includes a maximum of a first number of bits or a second number of bits, the first number of bits determined based at least in part on a first maximum rank when one sounding reference signal resource set is associated with the first uplink communication, and the second number of bits determined based at least in part on a second maximum rank when two sounding reference signal resource sets are associated with the first uplink communication.
