Feedback configuration for uplink control messages
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify, based on attributes of an uplink control information (UCI) message transmitted by the UE to a base station, whether transmitting the UCI message will trigger a feedback message from the base station. The UE may transmit the UCI message to a base station in uplink control channel resources. The UE may determine a feedback configuration corresponding to the UCI message based on attributes of the UCI message. The feedback configuration may indicate whether the UCI triggers a feedback message. The UE may monitor for the feedback message responsive to the UCI message based on the feedback configuration.
