A method for wireless communication at a user equipment, UE (115, 210, 405) configured to operate in a 3GPP system, comprising: transmitting (310, 415 1305, 1405) an autonomous uplink transmission to a base station using a configured resource set, the autonomous uplink transmission comprising reference signals and data signals; determining (420, 1310, 1410) whether a response signal was received from the base station (105, 205,410) in response to the autonomous uplink transmission; upon determining that the response signal was received (325, 425,1315, 1415), determining whether the response signal indicates that the base station received the reference signals but not the data signals, or the response signal indicates the base station received both the reference signals and the data signals; and selecting (330, 1320, 1420) an uplink transmission scheme to use for subsequent transmissions to the base station (105, 205,410), the selected uplink transmission scheme based at least in part on the determination of whether the response signal was received from the base station and whether the response signal indicates that the base station (105, 205,410) received the reference signals but not the data signals, or that the base station received both the reference signals and the data signals; decoding the response signal to determine an identifier for an updated configured resource set to use for retransmitting the autonomous uplink transmission, wherein the identifier is associated with the reference signals and the response signal is based on the identifier; and selecting, based at least in part on the identifier, the updated configured resource set to use for retransmitting the autonomous uplink transmission. transmitting (310, 415 1305, 1405) an autonomous uplink transmission to a base station using a configured resource set, the autonomous uplink transmission comprising reference signals and data signals; determining (420, 1310, 1410) whether a response signal was received from the base station (105, 205,410) in response to the autonomous uplink transmission; upon determining that the response signal was received (325, 425,1315, 1415), determining whether the response signal indicates that the base station received the reference signals but not the data signals, or the response signal indicates the base station received both the reference signals and the data signals; and selecting (330, 1320, 1420) an uplink transmission scheme to use for subsequent transmissions to the base station (105, 205,410), the selected uplink transmission scheme based at least in part on the determination of whether the response signal was received from the base station and whether the response signal indicates that the base station (105, 205,410) received the reference signals but not the data signals, or that the base station received both the reference signals and the data signals; decoding the response signal to determine an identifier for an updated configured resource set to use for retransmitting the autonomous uplink transmission, wherein the identifier is associated with the reference signals and the response signal is based on the identifier; and selecting, based at least in part on the identifier, the updated configured resource set to use for retransmitting the autonomous uplink transmission.
