IPC Code(s): G06N3/0455, G06N3/048
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: systems and methods are disclosed for resource selection in sidelink communications. in one embodiment, a method performed by a wireless communication device (wcd) for resource selection for a sidelink transmission comprises performing channel sensing of a channel to be used for sidelink transmission, determining a first set of resources that are available or not available from a perspective of the wcd based on results of performing the channel sensing, receiving one or more resource coordination messages from one or more neighboring wcds, determining one or more second set of resources that are available or not available from perspectives of the one or more neighboring wcds based on information comprised in the one or more resource coordination messages, and performing resource selection for a sidelink transmission based on the first set of resources and the one or more second sets of resources.

IPC Code(s): H04W72/542, H04L1/00, H04W24/02
Abstract: providing user device assisted link adaptation in communication networks is disclosed herein. in one embodiment, a method performed by a network node of a telecommunications network for optimizing selection of radio resources and transmission format for a communication session with a user device comprises receiving, by the network node, a link adaptation report message from the user device, wherein the link adaptation report message comprises a link adaptation report. the method further comprises determining a scheduling grant comprising an allocation of radio resources for the user device based on the link adaptation report. the method also comprises transmitting the scheduling grant to the user device.

IPC Code(s): H04W72/543, H04L41/16, H04W24/02, H04W28/02, H04W72/04
Abstract: a method and a network node for applying machine learning for training a communication policy controlling radio resources for communication of messages between the network node and a control node operating a remotely controlled device is provided. the network node obtains said messages during one or more communication phases communicated when an initial first communication policy is applied for controlling a quality of service, qos, mode. the network node trains a machine learning model based on said messages and the first communication policy. the network node produces a second communication policy including at least one adjusted qos mode for at least one communication phase. the network node determines a performance score for the second communication policy in the communication phase(s) based on the radio resources used when communicating using the second communication policy.

IPC Code(s): H04W74/08
Abstract: a method performed by a user equipment. the method is for providing first information to a network node. the user equipment and the network node operate in a wireless communications network. the user equipment sends a first indication to the network node. the first indication indicates whether or not first information is being provided. the first information comprises at least one of: a) a quality report on a carrier used between the network node and the user equipment, and b) second information on subsequent transmissions from the user equipment to the network node or from the network node to the user equipment. the first indication is comprised in a payload of a medium access control control element.
