    Abstract: A method performed by a first communication device for managing a decentralized autoencoder for detection or prediction of a minority class from an imbalanced dataset is provided. The method includes signalling a message to communication devices including a set of parameters for the decentralized autoencoder; and receiving a message from a communication device providing information including an amount of local samples and a distribution of labels in the local samples of instances of local majority class samples and/or the local minority class samples. The method further includes computing a computed number of samples and a computed distribution of labels for aggregated local majority class samples and aggregated local minority class samples; and selecting a set of communication devices to include in the decentralized autoencoder based on the communication devices that can satisfy the computed number of samples and the computed distribution of labels.

    Abstract: A signal loss compensation method, for compensating an input signal comprising (K+Y) lost signal units and normal signal units. The signal loss compensation method comprises: compensating 1st to (K−1)th lost signal units by a first signal loss concealment algorithm to generate a first compensation signal and accordingly generating a first synthetic signal; compensating (K+X+1)th to (K+Y) th lost signal units by a second signal loss concealment algorithm to generate a second compensation signal and accordingly generating a second synthetic signal; compensating K th to (K+X)th lost signal units by the first signal loss concealment algorithm or the second signal loss concealment algorithm to generate a third synthetic signal; generating an output signal according to the first synthetic signal, the second synthetic signal, the third synthetic signal and the normal signal units. K and Y are positive integers, X is a natural number, and Y is larger than X.

    Abstract: A transmitter is disclosed. The transmitter includes a clock configured to generate one or more output clock signals. The transmitter further includes at least one frequency divider configured to generate a plurality of divided frequencies based on the one or more output clock signals, and a modulator. The transmitter also includes at least one antenna or transducer configured to transmit modulated data. The transmitter includes a memory configured to store instructions, and at least one processor configured to execute instructions performing operations including mapping data to a decimal code value of a plurality of decimal code values, converting the decimal code value to a shrinking base system, and selecting a set of frequencies among the plurality of divided frequencies based on the code value corresponding to the shrinking base system for the decimal code value. The modulator may be configured to modulate the decimal code value using the set of frequencies.

    Abstract: Aspects relate to techniques for MCS selection of a packet to be network coded for sidelink communication. A transmitting UE may encode a packet using an MCS that is greater than a normal MCS that may be used for encoding the packet without network coding. The transmitting UE may then transmit the encoded packet to one or more receiving UEs and a network coding device over a sidelink data channel. The transmitting UE may further transmit a network coding request flag associated with the packet to initiate one or more retransmissions of the packet by the network coding device.
