Abstract: Apparatuses (and methods of manufacturing same), systems, and methods for channel interpolation/estimation and/or frequency tracking suitable for a receiver in a high speed single frequency network (HS-SFN) scenario are described. In one aspect, an estimated frequency offset (FO) correction is calculated for a received signal using at least an FO estimation provided by an automatic frequency control (AFC) in a first feedback loop and a channel estimate is calculated using at least the estimated FO and one or more channel parameter estimates from the AFC in a second feedback loop. In another aspect, a phase locked loop (PLL) receives an lth orthogonal frequency division multiplexing (OFDM) symbol and produces a per-tap phase value for each tap i of the lth OFDM symbol. The per-tap phase values of the lth OFDM symbol are used to generate the PLL output, which is also used as input to a feedback loop.

Abstract: A method of operation of a communication system includes: calculating a shift distance of a received signal having a distortion; calculating an approximate likelihood of the received signal matching a transmitted signal from the shift distance; determining a bias factor from the distortion; and selecting a determined modulation maximizing a combination of the approximate likelihood and the bias factor for communicating with a device.

Abstract: A method may include generating a receive timing error group (Rx TEG) based on a time delay of a receive (Rx) signal, wherein the time delay is a time measured from an arrival of the Rx signal at a Rx antenna to a time of the Rx signal being digitized and time-stamped at a baseband processor of a user equipment (UE), determining a timing error group (TEG) index corresponding to the generated Rx TEG, determining a positioning measurement associated with the Rx antenna used to generate the Rx TEG, and reporting the positioning measurement associated with the Rx TEG index.

Abstract: A system and a method are disclosed for processing data to be mapped into a transport block transmitted over a wireless physical shared channel. In one embodiment, a code block determination circuit determines a size of a code block of data that maps across at least one slot boundary of a slot of the wireless physical shared channel. A rate matching circuit rate matches bits of a code block to a number of bits available in the transport block that spans one or more slots of the wireless physical shared channel. An interleaver interleaves an output of the rate matching circuit so that a code block that crosses a slot boundary between a first slot and a second slot is interleaved between the first slot and the second slot.

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: Disclosed are methods for optimized capability signaling by a user equipment (UE). For the same level of control on the UE side in combining a previous release-N and a new release N+m, the UE should be able to utilize the existing signaling in release N together with the signaling in release N+m. Otherwise, if the UE only utilizes release N+m, the UE will be unable to have the benefit of the same level of control that was provided in release N.
