1. A method for wireless communication, comprising:
receiving, from a network node, a configuration message including a configuration for sending a downlink control information (DCI) feedback for a downlink control channel monitoring occasion, wherein the configuration indicates one or more of an uplink control channel resource and an uplink shared channel resource over which to send the DCI feedback, and wherein the DCI feedback includes one bit that can indicate an acknowledgement (ACK) where DCI is received during the downlink control channel monitoring occasion and a negative-ACK where DCI is not received during the downlink control channel monitoring occasion;
receiving, from the network node, a DCI over the downlink control channel during the downlink control channel monitoring occasion;
processing the DCI; and
transmitting, based on receiving the DCI and processing the DCI, DCI feedback to the network node over the one or more of the uplink control channel resource and the uplink shared channel resource indicated in the configuration, wherein transmitting the DCI feedback comprises transmitting the DCI feedback in a single uplink shared channel transmission, and wherein the DCI feedback in the single uplink shared channel transmission comprises feedback for DCIs received during multiple downlink control channel monitoring occasions.
