Abstract: There is provided an apparatus comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to perform: receiving, from a network node, a request for training data for data augmentation algorithm; transmitting, to the network node, a first part of a plurality of parts of the training data, wherein properties of data in the first part of the training data reflect distribution of the training data.

Abstract: According to an example aspect of the present disclosure, there is provided an apparatus comprising memory configured to store a set of probabilities of transitions between modulation symbols, the set of probabilities corresponding to a lower peak-to-average power ratio than a set of equal probabilities of transitions between modulation symbols, distribution matcher circuitry configured to process an input bit sequence into a symbol sequence, wherein frequencies of transitions between symbols in the symbol sequence conform to probabilities in the set of probabilities, a channel coder configured to generate parity bits of unity and negative unity from bit information obtained from the symbol sequence, grouping circuitry configured to assign symbols of the symbol sequence into groups each comprising two or more symbols, and multiplication circuitry configured to multiply each one of the groups with a corresponding one of the parity bits.

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.

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
