Feedback techniques for downlink control information on a physical downlink shared channel
Abstract:
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive multiple downlink control information (DCI) messages from a base station, where each of the multiple DCI messages schedules a respective downlink transmission. Some of the DCI messages may be multiplexed with downlink transmissions. The UE may identify, for each downlink transmission multiplexed with one of the multiple DCI messages, a time period including a beginning of the downlink transmission, and the UE may determine an order of the multiple DCI messages based on the time period. The UE may transmit a feedback message to the base station for the respective downlink transmissions based on the determined order. The UE may transmit the feedback message to the base station on uplink resources indicated by a last DCI message in the determined order.
