Abstract: Methods, systems, and devices for wireless communications are described that support signaling of compressed gradient vectors in a machine learning system that utilizes federated learning. The compressed gradient vectors may be used to report stochastic gradients from multiple edge devices (e.g., multiple user equipment (UE) devices) that are combined into a global model at an edge server (e.g., a base station). A base station may configure a UE with one or more parameters for quantizing a local stochastic gradient, and for reporting the quantized local stochastic gradient in a set of compressed gradient vectors. Each vector of the compressed gradient vectors may be associated with a different stage of a multi-stage compression procedure for reporting the local stochastic gradient, and multiple reports from multiple UEs may be aggregated in a federated learning procedure associated with a machine learning algorithm.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a channel state information (CSI) configuration indicating a first feedback reporting periodicity for a dominant, or strong, spatial layer and a second feedback reporting periodicity for a non-dominant, or weak, spatial layer. The UE may transmit a first CSI report for at least the dominant spatial layer according to the first feedback reporting periodicity. The UE may transmit a second CSI report for the non-dominant spatial layer according to the second feedback reporting periodicity. In some cases, for aperiodic reporting, the UE may be triggered by downlink control information to report CSI for the dominant spatial layer. In some cases, the CSI configuration may indicate different codebooks for the dominant and non-dominant spatial layers.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive, from a transmitting device, a configuration indicating a set of orbital angular momentum (OAM) modes for joint reporting, where at least one of the set of OAM modes is associated with transmission via two or more of a plurality of sets of antennas arranged in a set of concentric circular arrays. The receiving device may transmit, to the transmitting device, a report indicating precoding information for each of at least a subset of the set of OAM modes, where the precoding information includes one or more first parameters common to the set of OAM modes and one or more second parameters for respective ones of the at least the subset of the set of OAM modes.

Abstract: A method of wireless communication by a base station includes receiving a channel state information (CSI) payload at a neural network CSI decoder. The method also includes decoding the CSI payload to generate a quantity (N) of precoding vectors for N transmission layers. The method further includes orthogonalizing the N precoding vectors to generate N orthogonal precoding vectors. The method still further includes transmitting, to a user equipment (UE), downlink data that is precoded in accordance with the N orthogonal precoding vectors.

Abstract: Methods, systems, and devices for wireless communication are described. Neural networks may assist user equipments (UEs) and base stations in performing various operations related to wireless communications. For example, neural networks may be used to generate non-orthogonal cover codes for transmitting reference signals such as channel state information-reference signals (CSI-RSs). A base station may transmit, to a UE, a CSI-RS associated with a non-orthogonal cover code of a set of non-orthogonal cover codes. Using the CSI-RS, the UE may perform a channel estimation procedure that corresponds to the non-orthogonal cover code. Based on the channel estimation procedure, the UE may transmit a feedback message to the base station that indicates a channel quality parameter. Additionally, or alternatively, a UE may receive a CSI-RS, determine a precoding matrix using the CSI-RS and neural network, and transmit an indication of the pre-coding matrix to a base station.

Abstract: A configuration for reporting OOD samples for neural network optimization. The apparatus receives, from a base station, a configuration to report an OOD dataset for a machine learning model. The apparatus detects an occurrence of one or more OOD events. The apparatus reports the OOD dataset comprising the one or more OOD events based on the configuration to report OOD dataset. The apparatus receives, from the base station, an update to the machine learning model. The OOD dataset may comprise raw data related to the one or more OOD events, or may comprise extracted latent data corresponding to features of raw data related to the one or more OOD events.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, devices may implement multiple autoencoders for communications. A wireless device may select an autoencoder to use for communications based on a size parameter for a message. For example, a user equipment (UE) may receive a grant from a base station indicating a size parameter for communicating a message. The UE and base station may determine, from a set of neural network (NN)-based encoders configured at the UE, an NN-based encoder corresponding to the size parameter. The UE may communicate the message with the base station according to the grant and based on the determined NN-encoder. In some examples, the UE and base station may determine a number of resource segments from a set of resources allocated for communication and may determine respective NN-based encoders for the different resource segments.
