Abstract: Some embodiments of the present disclosure provide certification for the handling of an inference request that is transmitted to a DNN hosted on a remote computing system. Output data, received responsive to the inference request, may be certified as being appropriately generated by the DNN, rather than being tampered with or generated by a malicious DNN. Output data from the DNN may be also certified as appropriately corresponding to input data included in the inference request. Linear block coding may be used on transmissions to guard against eavesdropping and tampering. Through the use of a certification DNN, a degree of comfort may be gained that given output data appropriately corresponds to input data included in a given inference request.

Abstract: Some embodiments of the present application provide a forward-propagation-only (FP-only) method of training a DNN model. Such methods result in a trained DNN model whose performance comparable to a DNN model trained using bidirectional training methods. The FP-only method for training a DNN model may operate without employing the known chain rule. The chain rule is employed when computing gradients for a backward propagation in a bidirectional method. The FP-only method may allow for the computations and updates to the parameters for each layer of the DNN model to be performed in parallel. The FP-only methods for training a DNN model use stochastic gradient descent and the FP-only method for training a DNN model still involves computing gradients. However, the FP-only methods of training a DNN model allow for computing of gradients without the chain rule.

Abstract: A wireless network can generate candidate signal configurations for physical transmissions to or from a user equipment (UE) in a radio environment. The generation of candidate signal configurations can be performed using a first neural network that is associated with the UE. These signal configurations can then be evaluated using a second neural network that is associated with the radio environment. The second neural network can be trained using measurements from previous physical transmissions in the radio environment. The trained second neural network generates a reward value that is associated with the candidate signal configurations. The first neural network is then trained using the reward values from the second neural network to produce improved candidate signal configurations. When a signal configuration that produces a suitable reward value is generated, this signal configuration can be used for the physical transmission in the radio environment.

The transmit end sends the first feature to a receive end, where the first feature is used by the receive end to obtain the first data.

For example, one or more small URLLC messages (e.g. from sensors) can be combined with a video payload or an eMBB payload.

Abstract: Aspects of the present disclosure enable the determination of beamforming information and channel information for communication between a transmitter and receiver by using a propagation path map. The propagation path map may provide an association between a location of the receiver and channel characteristics between the transmitter and the receiver via a direct propagation path and possible reflection propagation paths. The propagation path map may be used to obtain a more accurate location of the receiver, AoA at the transmitter and/or receiver, AoD at the transmitter, and/or receiver and other sensing information for beamforming and improving the RF propagation map. The association between a location of the receiver and channel characteristics between the transmitter and the receiver may then aid in performing beam measurements and/or channel measurements.
