1. A method for wireless communications at a user equipment (UE), comprising:
transmitting a first uplink message corresponding to a first hybrid automatic repeat request (HARQ) identifier;
receiving, in a first HARQ monitoring occasion associated with the first HARQ identifier, a first positive acknowledgment HARQ message;
refraining, when in a first HARQ skipping mode, from monitoring a first subsequent HARQ monitoring occasion associated with the first HARQ identifier based at least in part on receiving the first positive acknowledgment HARQ message;
entering a periodic evaluation mode after a time threshold of operating in the first HARQ skipping mode;
initiating a periodic evaluation counter based at least in part on entering the periodic evaluation mode;
transmitting a second uplink message corresponding to a second HARQ identifier;
receiving, in a second HARQ monitoring occasion associated with the second HARQ identifier, a second positive acknowledgment HARQ message;
monitoring, when in the periodic evaluation mode, a second subsequent HARQ monitoring occasion associated with the second HARQ identifier based at least in part on receiving the second positive acknowledgment HARQ message; and
reentering the first HARQ skipping mode based at least in part on a threshold value of the periodic evaluation counter.
