1. A method for a user equipment (UE) configured to transmit hybrid ARQ (HARQ) feedback for data transmissions from a wireless network, the method comprising:
receiving, from the wireless network, a first data message associated with a first HARQ process and a second data message associated with a second HARQ process, wherein at least one of the first and second HARQ processes is disabled, and wherein the second data message is received after the first data message;
selectively transmitting, at a first occasion after the first data message, first HARQ feedback for the first data message based on whether the first HARQ process is enabled or disabled; and
selectively transmitting, at a second occasion after the second data message, second HARQ feedback for the second data message based on the following:
whether the second HARQ process is enabled or disabled,
an order of the first and second occasions, and
an out-of-order scheduling restriction applicable to data messages associated with different HARQ processes, wherein:
when the second occasion is not before the first occasion, the second HARQ feedback is selectively transmitted based on whether the second HARQ process is enabled or disabled; and
when the second occasion is before the first occasion, the second HARQ feedback is not transmitted.
