Communication methods and devices in intelligent transport systems
According to some embodiments, there is provided a Collective Perception Message, CPM, characterizing a plurality of Vulnerable Road Users based on a plurality of received VAMs, thereby allowing an ITS station to efficiently aggregate VAM messages from VRUs and retransmit information about the VRUs to other ITS stations.

According to other aspects, congestion is avoided while maintaining safety vis-à-vis VRUs thanks to the use of a different transmission scheme when the VRU is already characterized in a CPM sent to the ITS stations. Also, a receiving station can evaluate whether the content of a CPM can be trusted or not. Safety is thus improved. This is achieved thanks to the CPM that references a certificate. |

Network ID device history and mobile account attributes used as a risk indicator in mobile network-based authentication
An authorization process employs a network ID as a possession factor for a secure account, such as a bank account or e-mail account, and determines one or more risk indicators associated with the possession factor. The authorization process is successfully completed when a risk score that is based on the risk indicators is less than a certain risk threshold. The risk indicators include a device history of the network ID and/or at least one attribute of a cellular account associated with the network ID. The device history identifies other mobile devices and/or SIM cards, if any, that have been previously activated with the network ID, while the one or more attributes can further indicate potentially fraudulent activity associated with the cellular account through which wireless services for the network ID are currently provided. |

Transmitting and storing different types of encrypted information using TCP urgent mechanism
A network device decrypts a record, received from a client device, that is associated with an encrypted session between the client device and an application platform. The network device incorporates decrypted record data, from the decrypted record, into a payload field of a transmission control protocol (TCP) packet to be transmitted to another device, identifies a record header in the record, and determines, based on the record header, a record type associated with the decrypted record. Based on the record type, the network device marks the one or more TCP packets as including urgent data by setting a TCP urgent control bit in a header of the one or more TCP packets, and sets a second field, in the header of the TCP packet, to a second value that identifies an end of the urgent data, which corresponds to an end of the decrypted record data in the payload field. |

End-to-end encryption for personal communication nodes
Systems, methods, software and apparatus enable end-to-end encryption of group communications by implementing a pairwise encryption process between a pair of end user devices that are members of a communication group. One end user device in the pairwise encryption process shares a group key with the paired end user device by encrypting the group key using a message key established using the pairwise encryption process. The group key is shared among group members using the pairwise process. When a transmitting member of the group communicates with members, the transmitting member generates a stream key, encrypts stream data using the stream key, encrypts the stream key with the group key, then transmits the encrypted stream key and encrypted stream data to group members. The group key can be updated through the pairwise encryption process. A new stream key can be generated for each transmission of streaming data such as voice communications. |

Orthogonal time frequency space modulation techniques
Orthogonal Time Frequency Space (OTFS) is a novel modulation scheme with significant benefits for 5G systems. The fundamental theory behind OTFS is presented in this paper as well as its benefits. We start with a mathematical description of the doubly fading delay-Doppler channel and develop a modulation that is tailored to this channel. We model the time varying delay-Doppler channel in the time-frequency domain and derive a new domain (the OTFS domain) where we show that the channel is transformed to a time invariant one and all symbols see the same SNR. We explore aspects of the modulation like delay and Doppler resolution, and address design and implementation issues like multiplexing multiple users and evaluating complexity. Finally we present some performance results where we demonstrate the superiority of OTFS. |

Low resolution OFDM receivers via deep learning
Various embodiments provide for deep learning-based architectures and design methodologies for an orthogonal frequency division multiplexing (OFDM) receiver under the constraint of one-bit complex quantization. Single bit quantization greatly reduces complexity and power consumption in the receivers, but makes accurate channel estimation and data detection difficult. This is particularly true for OFDM waveforms, which have high peak-to average (signal power) ratio in the time domain and fragile subcarrier orthogonality in the frequency domain. The severe distortion for one-bit quantization typically results in an error floor even at moderately low signal-to-noise-ratio (SNR) such as 5 dB. For channel estimation (using pilots), various embodiments use novel generative supervised deep neural networks (DNNs) that can be trained with a reasonable number of pilots. After channel estimation, a neural network-based receiver specifically, an autoencoder jointly learns a precoder and decoder for data symbol detection. |

The user interface may be updated as various contextually-related data is received. For example, data representing a current position of the mobile device, such as Bluetooth low energy beacon signals, WiFi signals, and the like, may be monitored. In response to determining that the current position is within a threshold proximity of a first location, the user interface may be updated to emphasize a first location interface corresponding to the first location over interfaces corresponding to other locations. |

Techniques for conducting a virtual event are described. One example method includes displaying, on a display screen of a computing device, a plurality of icons, each icon representing a different virtual event participant, wherein the plurality of icons includes a first icon representing a virtual event participant associated with the computing device; receiving, from an input device of the computing device, input representing a direction of movement for the first icon; and in response to receiving the input, moving the first icon on the display screen in the direction represented by the input. |
