Configuration of uplink hybrid automatic repeat request processes and process types

A network node, comprising:

• a memory;
• and
• at least one processor coupled to the memory,
• wherein the memory and the at least one processor are configured to:
• send, to a user equipment (UE), an uplink (UL) grant for a physical uplink shared channel (PUSCH) associated with a hybrid automatic repeat request (HARQ) process;
• and
• receive an UL message transmitted by the UE on the PUSCH using a transmit configuration in accordance with the associated HARQ process, the transmit configuration being one of a plurality of transmit configurations, and at least two of the plurality of transmit configurations being different from each other.

A user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory,
• wherein the memory and the at least one processor are configured to:
• receive, from a network node, an uplink (UL) grant for a physical uplink shared channel (PUSCH) for a hybrid automatic repeat request (HARQ) process;
• receive, from the network node contemporaneously with the UL grant for the PUSCH, a transmit configuration indicator indicating a transmit configuration of a plurality of transmit configurations to be associated with the HARQ process;
• and
• transmit, to the network node, an UL message on the PUSCH using the indicated transmit configuration.
