1. A method of wireless communication, comprising:
determining, by a base station (BS), a plurality of sounding reference signal (SRS) resources for at least a first user equipment (UE), wherein a first SRS resource of the plurality of SRS resources includes a different quantity of SRS ports than a second SRS resource of the plurality of SRS resources;
transmitting, by the BS to the first UE, a configuration indicating the plurality of SRS resources; and
transmitting, by the BS to the first UE, a further request to activate a plurality of SRS ports within the plurality of SRS resources for a second SRS transmission, wherein a quantity of the plurality of SRS ports is greater than a quantity of spatial layers currently supported by the first UE.
