Abstract: The present invention provides a terminal capable of suitably performing random access processing. In a terminal (100), a RACH resource determination unit (104) determines the format of a random access signal on the basis of a parameter related to the transmission of the random access signal, which includes a preamble part and a data part. A wireless transmission unit (109) transmits the random access signal on the basis of the format.

Abstract: The present disclosure relates to a transmitting device for transmitting vehicular data via a sidelink interface to one or more receiving devices. The transmitting device performs autonomous radio resource allocation for transmitting the vehicular data via the sidelink interface. An application layer generates the vehicular data and forwards the vehicular data together with a priority indication and one or more quality of service parameters to a transmission layer responsible for transmission of the vehicular data via the sidelink interface. The transmission layer performs autonomous radio resource allocation based on the received priority indication and the one or more quality of service parameters. The transmission layer transmits the vehicular data via the sidelink interface to the one or more receiving devices according to the performed autonomous radio resource allocation.

Abstract: A gateway device is connected via network(s) to electronic controllers on-board a vehicle, where at least one of the electronic controllers is implemented in a virtual machine. The gateway device includes one or more memories, and circuitry that acquires firmware update information. The circuitry determines whether a first electronic controller satisfies a second condition based on second information, which is whether the first electronic controller includes a firmware cache for performing a pre-update firmware cache operation. The circuitry also causes, when the second condition is not satisfied, the gateway device to execute a proxy process, where the gateway device requests the first electronic controller to transmit boot ROM data to the gateway device, creates updated boot ROM data with the updated firmware, and transmits the updated boot ROM data to the first electronic controller that updates the boot ROM and resets the first electronic controller with the updated firmware.

Abstract: A method that generates binaural headphone playback signals given multiple audio source signals with an associated metadata and binaural room impulse response (BRIR) database, wherein the audio source signals are channel-based, object-based, or a mixture of both channel-based and object-based signals. The method includes parameterizing BRIR to be used for rendering, dividing each audio source signal to be rendered into a number of blocks and frames, and averaging the parameterized BRIR sequences. The method also includes downmixing the divided audio source signals using the diffuse blocks of BRIRs, and performing late reverberation processing on the downmixed version of the previous blocks of the audio source signals.

Abstract: Provided is a method for transmitting a broadcasting content and a line content, the broadcasting content and the line content being synchronously displayed, the method including: generating a line parity packet from a plurality of line data packets in each of which the line content is stored; transmitting the line data packet and the line parity packet through a communication line; and transmitting a plurality of broadcasting data packets in each of which the broadcasting content is stored, from a base station using a broadcasting wave, a transfer clock time of the broadcasting content being delayed by a predetermined time compared with a transfer clock time of the line content. At this point, video quality can be improved when the real-time broadcasting program content and the real-time line content are simultaneously displayed.
