1. A method of wireless communication by a user equipment (UE), comprising:
receiving one or more downlink control channels that schedule a downlink data channel for the UE and that indicate both a first acknowledgement or negative acknowledgement (ACK/NACK) resource for an early ACK/NACK and a second ACK/NACK resource for a regular ACK/NACK, the one or more downlink control channels including a first offset indication having a first value for a first time offset between the downlink data channel and the first ACK/NACK resource, the one or more downlink control channels including
a second offset indication having a second value for a second time offset between the downlink data channel and the second ACK/NACK resource, wherein the second value is larger than the first value;
partially decoding the downlink data channel based at least in part on the one or more downlink control channels; and
transmitting the early ACK/NACK using the first ACK/NACK resource via an uplink control channel upon partially decoding the downlink data channel and before completely decoding the downlink data channel, wherein the early ACK/NACK indicates that the partial decoding of the downlink data channel was unsuccessful.
