A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a base station. The apparatus may transmit a message to a user equipment (UE). The message may indicate a first dedicated resource for downlink transmission, and the first dedicated resource may be associated with a scheduled downlink transmission from the apparatus. The apparatus may receive an information message from the UE on a second dedicated resource for uplink transmission based on the first dedicated resource for downlink transmission indicated in the message. The information message may be used for transmitting the scheduled downlink channel transmission that was scheduled before the information message was received. The apparatus may transmit the scheduled downlink transmission after receiving the information message from the UE. The scheduled downlink transmission may be based on the received information message.
