16. A method for wireless communications at a user equipment (UE), comprising:
connecting to a network entity over a first component carrier and a second component carrier according to a carrier aggregation configuration;
receiving, from the network entity, downlink control information comprising a joint field comprising one or more of: a rate matching indication for the first component carrier and the second component carrier or a zero power reference signal indication for the first component carrier and the second component carrier;
determining a zero power reference signal configuration for the first component carrier and the second component carrier based at least in part on the joint field for the zero power reference signal indication;
receiving, from the network entity and via downlink control information, a trigger field for a set identifier associated with the zero power reference signal indication;
determining a resource set for the zero power reference signal indication based at least in part on the set identifier, wherein the resource set is used for the first component carrier and the second component carrier;
determining that a component carrier of the carrier aggregation configuration is not configured with a zero power reference signal resource set corresponding to the determined resource set, wherein the trigger field is ignored for the component carrier based at least in part on the determination that the component carrier is not configured with the zero power reference signal resource set; and
communicating with the network entity according to the carrier aggregation configuration based at least in part on the downlink control information comprising the joint field.
