Abstract: An image decoder includes circuitry and a memory, wherein the circuitry, in operation, performs a boundary smoothing operation along a boundary between a first partition having a triangular shape and a second partition having a triangular shape that are split from an image block. The boundary smoothing operation includes: first-deriving a first motion vector for the first partition from a first set of motion vector candidates; second-deriving a second motion vector for the second partition from a second set of motion vector candidates; first-predicting first values of a set of pixels of the first partition along the boundary, using the first motion vector; second-predicting second values of the set of pixels of the first partition along the boundary, using the second motion vector; weighting the first values and the second values; and decoding the first partition using the weighted first values and the weighted second values.

Abstract: A decoder that includes: circuitry; and a memory coupled to the circuitry. The circuitry, in operation: determines whether or not a first splitting of splitting a block into three sub blocks in a first direction parallel to a first side of the block is available by determining a magnitude relation between a size of a second side of the block and a first value, the second side being different from the first side, the first side being a longer side of the block; when the first splitting is available, parses, from a bitstream, a split direction parameter indicative of a splitting direction; splits the block into a plurality of sub blocks in a direction indicated by the split direction parameter; and decodes the plurality of sub blocks.

Abstract: A gateway device connected to a network used in communication by multiple electronic control units provided on-board a vehicle. The gateway device performs operations including receiving firmware update information that includes updated firmware for one electronic control unit among the electronic control units, and acquiring system configuration information indicating a function of each of the electronic control units connected to the network. The gateway device further performs a controlling operation to update firmware of the one electronic control unit, for which updated firmware is received by the receiving, on a basis of the updated firmware, after an operation verification of the updated firmware is performed in an operating environment appropriately. The operating environment being configured with electronic control units of the same functions as each of the electronic control units indicated by the system configuration information.

Abstract: A transmission apparatus includes a plurality of orthogonal frequency division multiplexing (OFDM) modulation signal generators, which generate a first OFDM modulation signal and a second OFDM modulation signal. The transmission apparatus also includes a transmitter that transmits the first OFDM modulation signal from a first antenna and the second OFDM modulation signal from a second antenna, in an identical frequency band. A reception apparatus is provided, which includes a plurality of antennas that receive a plurality of OFDM modulation signals; a plurality of OFDM demodulators that transform the plurality of OFDM modulation signals to a plurality of reception signals using Fourier transform; an estimator that outputs a distortion estimation signal using one or more symbols for demodulation included in the plurality of reception signals; and a demodulator that compensates for distortion of the reception signals using the distortion estimation signal and demodulates a data symbol included in the reception signals.

Abstract: A communication apparatus includes circuitry that determines a number of resource blocks forming a resource block group, which is a unit used to allocate a resource to the communication apparatus, in a first band or in a second band that is an expanded band to which the first band is expanded, and a subcarrier spacing for the second band is same or different from a subcarrier spacing for the first band; and a transceiver that is coupled to the circuitry and that communicates with a base station using the resource. One of the number of resource blocks set for the first band and the number of resource blocks set for the second band is an integer multiple of the other, and the number of resource blocks set for the first band and the number of resource blocks set for the second band are values that are a power of two.
