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.

Abstract: Systems, methods, apparatuses, and computer program products for probabilistic amplitude shaping (PAS) are provided. One method may include selecting a distribution parameter for one constellation in a communications system depending on one or more flat fading channels, transforming a uniform distribution of the constellation into a shaped distribution using the selected distribution parameter to produce modulated data, and passing the modulated data through a fading channel.

Abstract: An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: determine (1006) whether at least one transport block has been successfully delivered to another apparatus; and determine (1008, 1010, 1012) whether to use the at least one transport block to scramble at least one subsequent transport block based on whether the at least one transport block has been successfully delivered to the apparatus.
