1. A method of wireless communications by a user equipment (UE), comprising:
receiving, from a base station, a configuration message indicating one or more parameters for the UE to receive a semi-persistent scheduling (SPS) message;
receiving, from the base station, a message indicating activation or reactivation of SPS between the UE and the base station, wherein the message further indicates a first resource for transmitting a first acknowledgement/negative-acknowledgement (ACK/NACK) to acknowledge reception of the message, a first offset value for the first ACK/NACK, and a second offset value for a second ACK/NACK to acknowledge reception of the SPS message;
transmitting, to the base station and based on the first offset value, the first ACK/NACK on the first resource to acknowledge reception of the message;
receiving, from the base station and subsequent to the receiving of the message, the SPS message;
determining, from the configuration message, a second resource for transmitting the second ACK/NACK to acknowledge reception of the SPS message; and
transmitting, to the base station and based on the second offset value, the second ACK/NACK on the second resource.
