Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for determining radio frequency (RF) conditions using sensing information. A network node may construct a map of RF conditions associated with location information within its coverage area. The network node may configure a radio resource control (RRC)-connected UE to operate in an RF sensing mode. The network node may obtain a positioning of the UE from a sensing node. The network node may determine the RF conditions of the UE based on its position using the map.

Abstract: Embodiments described herein encode data for multiple-segment transmission in a communication channel by encoding payload bits with an outer code and distributing the outer encoded payload bits to a plurality of N element coders, where N is an integer greater than one. At each of the N element coders the respectively input outer encoded payload bits are encoded with a respective element code. Outputs of the N element coders are encoded with an inner code such that the inner code applied to at least one of the outputs of the N element coders is a function of the output of at least one other of the N element coders. Finally, N discrete inner coded outputs are provided for transmission in respective N discrete segments of a wireless channel. The examples present polar element coders and the inner code combines outputs of certain element coders with an exclusive-OR function.

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: In some example embodiments, there may be provided a method that includes receiving, by a machine learning encoder as part of a training phase, channel state information as data samples; generating, by the machine learning encoder, a latent variable comprising a log likelihood ratio value representation for the channel state information, wherein the latent variable provides a lower dimension binary representation when compared to the received channel state information to enable compression of the received channel state information; generating, by the binary sampler, a binary coding value representation of the latent variable, wherein the binary coding value converts the latent variable to a binary form; and generating, by the machine learning decoder, a reconstructed channel state information, wherein the generating is based in part on the binary coding value representation of the latent variable generated by the binary sampler. Related systems, methods, and articles of manufacture are also disclosed.

Abstract: A method for encoding a sequence of control information bits comprising: generating a sequence of error detection bits based on the sequence of control information bits; generating a sequence of error correction bits based on the sequence of control information bits; and distributing the sequence of error detection bits and the sequence of error correction bits between the sequence of control information bits to form a combined sequence of bits, such that the bit order of the combined sequence of bits following the distribution enables an error detection check to be performed before or after a first error correction check bit.
