  • Publication number: 20220141839
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules an aperiodic channel state information reference signal (CSI-RS) report. The UE may determine, based at least in part on the DCI, a time duration between an end of the DCI and a start of a communication on a physical uplink shared channel that includes the aperiodic CSI-RS report. The time duration may be based at least in part on an aperiodic CSI beam switch latency threshold. The UE may generate the aperiodic CSI-RS report based at least in part on a CSI-RS measurement. The UE may transmit the aperiodic CSI-RS report based at least in part on the DCI associated with the time duration. Numerous other aspects are provided.

    Abstract: Aspects for predicting communication configurations for a wireless node are provided. Assisting information is measured or assessed at a first wireless node. The assisting information may include clutter and blocker measurements, self-interference measurements, and various beam, frequency, and modulation-related measurements. A control node may determine a communication configuration based on the assisting information. The communication configuration may be predicted for use at a subsequent time period. The first wireless node may receive and approve the configuration. The first wireless node may use the communication configuration in a subsequent communication with a second wireless node. The communication configuration may include, for example, whether the first wireless node will communicate using a full-duplex or half-duplex configuration and the TX/RX beam configuration for the node.

    Abstract: A transformer-transducer model for unifying streaming and non-streaming speech recognition includes an audio encoder, a label encoder, and a joint network. The audio encoder receives a sequence of acoustic frames, and generates, at each of a plurality of time steps, a higher order feature representation for a corresponding acoustic frame. The label encoder receives a sequence of non-blank symbols output by a final softmax layer, and generates, at each of the plurality of time steps, a dense representation. The joint network receives the higher order feature representation and the dense representation at each of the plurality of time steps, and generates a probability distribution over possible speech recognition hypothesis. The audio encoder of the model further includes a neural network having an initial stack of transformer layers trained with zero look ahead audio context, and a final stack of transformer layers trained with a variable look ahead audio context.
