Abstract: Methods and apparatuses for noise learning-based denoising of noisy input data Y that is equal to the original data X plus the noise N (i.e., Y=X+N). In contrast with a conventional denoising autoencoder (DAE) method that attempts to learn the original data X directly from noisy input data Y, the noise learning-based denoising learns the noise N in the noisy input data Y and then regenerates the original data X by subtracting the learned noise N from the noisy input data Y. Learning the noise N may include inputting the noisy input data Y into an encoder of a neural network, and the learned noise N may be output from a decoder of the neural network. Training the neural network may include inputting noisy training data into an encoder of the neural network and outputting training noise from a decoder of the neural network.

Abstract: Embodiments include methods, performed by a network node, for configuring a physical random-access channel (PRACH) of a cell in a time-division-duplexed (TDD) radio access network (RAN). The methods include determining an increase in a level of remote interference in the cell and, in response to determining the increase, selecting a first PRACH configuration from a first subset of available PRACH configurations. The first subset of available PRACH configurations can be more robust against remote interference than a second subset of the available PRACH configurations, and the first subset can be exclusive of the second subset. The methods also include transmitting, to one or more user equipment (UEs) first information indicating that the first PRACH configuration should be used for accessing the cell via the PRACH. Embodiments also include complementary methods performed by UEs, as well as network nodes and UEs configured to perform such methods.
