Abstract: In a Non-Orthogonal Multiple Access (NOMA) system, a user equipment (UE) can be configured to transmit signals with multiple access (MA) signatures. If a base station configures multiple MA signatures to a UE, the UE can select one or more MA signatures, then transmit signals in parallel, serial, or in hybrid ways. Due to the flexibility and complexity of the UE selecting MA signatures without an explicit configuration from the base station, additional control overhead is provided to support parallel HARQ processing. In addition, a new DCI format is disclosed that supports multi-branch NOMA transmission, which allows multiple ACK/NACKs within a DCI. Further, using the techniques disclosed herein, a base station can explicitly indicate ACK-NACKs without being assisted by a HARQ ID field.

Abstract: A system is provided along a route of a network including a first transponder at a first node and a second transponder at a second node. The system further includes one or more processors configured to detect, in a first waveform measured at the first transponder, a first signature at a first time point, and configured to detect, in a second waveform measured at the second transponder, a second signature at a second time point. The one or more processors may correlate the first waveform and the second waveform, and determine, based on the correlation, that the first signature and the second signature correspond to a same event occurring along the route of the network. Based on comparing the first time point and the second time point, the one or more processors may determine an estimated location of the event.

Abstract: A client system presents, within an execution environment of an application, a third-party media stream distinct from the application, received from a remote host server via a network. The client system detects interaction events during presentation of the third-party media stream, and transmits descriptions of the detected interaction events to the remote host server. The application may be pre-cued prior to presentation, e.g., to minimize start-up time. In some implementations, a side-band message channel is established to facilitate communication between the client system and the remote host server.

Abstract: This specification describes computer-implemented methods and systems. One method includes receiving, by a neural network of a speech recognition system, first data representing a first raw audio signal and second data representing a second raw audio signal.

The method further includes generating, by a spatial filtering layer of the neural network, a spatial filtered output using the first data and the second data, and generating, by a spectral filtering layer of the neural network, a spectral filtered output using the spatial filtered output. Generating the spectral filtered output comprises processing frequency-domain data representing the spatial filtered output. The method still further includes processing, by one or more additional layers of the neural network, the spectral filtered output to predict sub-word units encoded in both the first raw audio signal and the second raw audio signal.

Abstract: A service provider system registers with a service system. A user establishes an account with the service system and the service system establishes a facial template associated with the user account. The service system transmits, to a service provider device at a location, identification information and transmits a shared encryption key to a user computing device associated with the user. The user enters the merchant location carrying the user computing device. The service device receives the encryption key from the user device and decrypts the identification information associated with the user using the encryption key. The user initiates a service request and the service provider device verifies the identity of the user via the facial template associated with the user by generating a facial template based on an image captured of the user to compare against the facial template associated with the user. The service device processes the service request.
