Abstract: A method includes generating an input data state for each data sample in a time series of data samples of a portion of an audio data stream. The method also includes providing at least one input data state to a first bottleneck and at least one other input data state to a second bottleneck. The first bottleneck is associated with a first bitrate and the second bottleneck is associated with a second bitrate. The method further includes generating a first encoded frame based on a first output data state from the first bottleneck and a second encoded frame based on a second output data state from the second bottleneck. The first encoded frame and the second encoded frame are bundled in a packet.

Abstract: A device includes a neural network and a sample generator. The neural network is configured to process one or more neural network inputs to generate a joint probability distribution. The one or more neural network inputs include at least first previous sample data and second previous sample data associated with at least one previous data sample of a sequence of data samples. The sample generator is configured to generate first sample data and second sample data based on the joint probability distribution. The first sample data and the second sample data are associated with at least one data sample of the sequence of data samples.

Abstract: Systems and techniques are provided for distributed processing. For instance, a process can include transmitting a discovery message, receiving a response to the discovery message, the response including an identifier of a neighboring device, transmitting an offloading request to an offloading server, the offloading request including the identifier of the neighboring device, receiving, from the offloading server, an indication that the neighboring device is selected to perform offloaded processing, transmitting data for processing to the neighboring device, receiving, from the neighboring device, processed data, and transmitting an indication of an amount of completed offloaded processing.

Abstract: A method for wireless communication by a wireless device includes receiving a first bit sequence and a second bit sequence from an upper layer of a wireless communication protocol stack. The first bit sequence is assigned a first class and the second bit sequence is assigned a second class. The second bit sequence is included in a same medium access control (MAC) packet data unit (PDU) as the first bit sequence. The method also includes processing, at a physical layer, the first bit sequence with a first quality of service (QoS) level, and the second bit sequence with a second QoS level that is different from the first QoS level.

Abstract: Techniques are described for coding audio signals. For example, using a neural network, a residual signal is generated for a sample of an audio signal based on inputs to the neural network. The residual signal is configured to excite a long-term prediction filter and/or a short-term prediction filter. Using the long-term prediction filter and/or the short-term prediction filter, a sample of a reconstructed audio signal is determined. The sample of the reconstructed audio signal is determined based on the residual signal generated using the neural network for the sample of the audio signal.

Abstract: Systems and techniques are described for coding audio signals. For example, a voice decoder can generate, using a first neural network, an excitation signal for at least one sample of an audio signal at least in part by performing a non-linear operation based on one or more inputs to the first neural network, the excitation signal being configured to excite a learned linear filter. The voice decoder can further generate, using the learned linear filter and the excitation signal, at least one sample of a reconstructed audio signal. For example, a second neural network can be used to generate coefficients for one or more learned linear filters, which receive as input the excitation signal generated by the first neural network trained to perform the non-linear operation.

Abstract: A receiver receives a first message including a first PDCP SN. The receiver may receive a second message including a second PDCP SN. The receiver may derive a second RTP SN based on at least one of a first RTP SN of the first message, the first PDCP SN, the second PDCP SN, or an RTP SN field of a second PDCP header composing the second message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may obtain an erroneous packet from a first communication device. The network node may output an indication of bit error rate information, based on the erroneous packet, to a second communication device to facilitate error mitigation at the second communication device. Numerous other aspects are described.

Abstract: The disclosure generally relates to various methods to increase network coverage with respect to Voice-over-Internet Protocol (VoIP) sessions and/or other voice-based multimedia services. In particular, when establishing a voice session, two or more terminals may perform a codec negotiation to exchange information related to supported multimedia codecs and/or codec modes, jitter buffer management (JBM), and packet loss concealment (PLC) capabilities. Based on the exchanged information, a message may be sent to a base station to indicate the maximum packet loss rate (PLR) for each terminal. Additional techniques may ensure that the terminals use the most robust codecs or codec modes that are available when nearing the edge of coverage to help avoid unnecessary and/or excessive handovers to different radio access technologies.
