    Abstract: Systems, methods, apparatuses, and computer program products for inconsistency free pipelined hybrid automatic repeat request scheme for non-terrestrial network channels. A method may include reserving or receiving reservation of physical layer resources exclusively for redundant transmission; allocating the physical layer resources and a predetermined number of transmit blocks, wherein the predetermined number of transmit blocks are associated with a downlink control information (DCI); checking a number of hybrid automatic repeat request process identifiers that are eligible for redundant transmission; and splitting the physical layer resources based on the number of hybrid automatic repeat request process identifiers that are eligible for redundant transmission.
