Methods and Apparatus for Disabled HARQ Processes

A method for a UE (1700) to transmit HARQ feedback for data transmissions from a wireless network is disclosed. The UE receives (1530), from the network, a first data message associated with a first HARQ process and a second data message associated with a second HARQ process. At least one of the first and second HARQ processes is disabled. The second data message is received after the first data message. The UE selectively transmits (1560), 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. The UE selectively transmits, 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.
