摘要： Methods, systems, and devices for contention-based transmissions using differential coding techniques in mobile communication technology are described. An exemplary method for wireless communication includes transmitting, by a wireless device, a payload that comprises an identity of the wireless device and at least one of a user plane data or a control plane data, where the payload is modulated using a differential coding technique. Another exemplary method for wireless communication includes receiving, by a network node, a payload that comprises an identity of the wireless device and at least one of a user plane data or a control plane data, where the payload is modulated using a differential coding technique.

摘要： A multi-user code division multiple access communication method, and corresponding transmitter and receiver include: the transmitter determines a complex-valued spreading sequence to be used by the transmitter, herein each element of the complex-valued spreading sequence is a complex number and values of real and imaginary parts of all elements in the complex-valued spreading sequence are from an M-element set of real numbers, and M is an integer larger than or equal to 2; the transmitter performs spreading processing on data symbols to be sent by using the complex-valued spreading sequence to generate a spread symbol sequence; and sends the spread symbol sequence. The receiver receives signals transmitted by multiple transmitters, and performs reception detection by using an interference cancellation signal detector, herein the complex-valued spreading sequences used by the multiple transmitters are used during detection.

摘要： Techniques are described for a full duplex communication method and apparatus for inter-vehicle communication (V2V). A communication apparatus includes one or more transmit antennas, one or more receive antennas, and a processor. For cases where a single transmit antenna and multiple receive antennas are used, a distance between the transmit and receive antennas is greater than a pre-determined value. Further, the transmit antenna is located on or in a central region of a top surface of the vehicle and the receive antennas are evenly distributed located on the vehicle. The processor configured to generate one or more messages to be transmitted via the transmit antenna, where the one or more messages includes vehicle condition information, operational information about a driver of the vehicle, or information associated with one or more sensors of the vehicle.
