Abstract: A system and a method may include a receiver circuit configured to receive an encoded codeword over a channel from an encoder neural network of an encoder, and a decoder circuit, including a decoder neural network, configured to decode the encoded codeword, and generate a list of decoded message words, the list of the decoded message words including a plurality of candidate message words representing the message word.

Abstract: A symmetric interleaver for a Convolutional Neural Network (CNN) and Recurrent Neural Network (RNN) encoder and a circular padding mode are disclosed. The interleaver interleaves elements of an input block to form an output block in which an output neighborhood of elements for each element of the output block is symmetric to an input neighborhood of elements for each element of the input block. A position of an element of the input block is interleaved based on an index i of the position times a parameter δ modulo K in which the parameter δ is relatively prime with K. A test loss function may be used to train the encoder that includes a Binary Cross Entropy (BCE) loss function plus a function that minimizes a number of codeword pairs based on a Euclidean distance. The RNN encoder may be implemented as part of a Turbo Autoencoder (TurboAE) encoder.

Abstract: A method of training an autoencoder that includes encoder neural networks and decoder neural networks. The method includes training the encoder neural networks in which weights of the decoder neural networks are fixed. The method also includes iteratively training the decoder neural networks for a number of iterations. For each iteration of the training of the decoder neural networks, a pair of decoder neural networks is replaced by another pair of neural networks, and a second decoder neural network of the pair of decoder neural networks utilizes different parameters than a first decoder neural network of the pair of decoder neural networks.

Abstract: A method of enabling communication between a user equipment (UE) and a non-terrestrial network (NTN), is described. The UE may be able to calculate a timing advance compensation. The timing advance compensation may be a differential or full timing advance compensation. An offset value, Koffset, may be indicated to the UE. The Koffset value may be used for timing relationships.

Abstract: A system and method for random access procedures in a non-terrestrial network. In some embodiments, the method includes calculating, by a user equipment (UE), a timing advance based on location information of the UE and on an ephemeris of a non-terrestrial network node. The method may further include randomly selecting a random value from a plurality of values, and sending, at a transmission time, by the UE, to the non-terrestrial network node, a random access (RA) message, which may include a signature. The transmission time may differ from a nominal transmission time by an amount based on the random value, the nominal transmission time being based on the timing advance, or the signature may differ from a nominal signature by a cyclic shift based on the random value.
