Abstract: An encoder includes circuitry and memory. Using the memory, the circuitry, in inter prediction processing: derives a first motion vector of a current block to be processed, using a motion vector of a previous block which has been previously processed; derives a second motion vector of the current block by performing motion estimation in the vicinity of the first motion vector; and generates a prediction image of the current block by performing motion compensation using the second motion vector.

Abstract: A base station selects, from among a plurality of code sequences orthogonal to one another, one code sequence by which an uplink signal including a demodulation reference signal repeated in a plurality of subframes is multiplied and transmits, to a terminal for which transmission of the repeated uplink signal is configured, information indicating the selected code sequence by using a field for indicating a cyclic shift and an orthogonal sequence used for the demodulation reference signal. A terminal receives information indicating one of a plurality of code sequences orthogonal to one another using a field for indicating a cyclic shift and an orthogonal sequence used for a demodulation reference signal and multiplies an uplink signal including the demodulation reference signal repeated in a plurality of subframes by the code sequence indicated by the information.

Abstract: A three-dimensional data encoding method includes: generating frame data items by encoding point cloud data items of frames; and generating a bitstream including the frame data items. Each of the frame data items includes processing unit data items corresponding to processing units obtained by dividing one frame. Each of the processing unit data items includes a frame identifier indicating a frame to which the processing unit data item belongs and a processing unit identifier indicating a processing unit corresponding to the processing unit data item. Values of the frame identifiers corresponding to the frame data items placed in the bitstream are set in a predetermined order, and values of the processing unit identifiers corresponding to the processing unit data items placed in the frame data item are set in an arbitrary order.

Abstract: The present disclosure provides a communication apparatus including circuitry, which, in operation, generates a transmission signal that includes a signal field and a data field, the signal field indicating one or more user-specific allocations in the data field. An aggregate medium access control protocol data unit (A-MPDU) transmitted in each of the one or more user-specific allocations is segmented into one or more code blocks. The communication apparatus includes a transmitter, which, in operation, transmits the generated transmission signal and a receiver, which, in operation, receives a null data packet (NDP) or a medium access control (MAC) frame carrying hybrid automatic repeat request (HARQ) feedback information for the one or more code blocks.

Abstract: A three-dimensional data encoding method includes: performing motion compensation by correcting position information of one or more first three-dimensional points to be matched to a coordinate system of a current three-dimensional point to be encoded, to generate a first reference point cloud; selecting, from one of the first reference point cloud or a second reference point cloud, a prediction point of the current three-dimensional point, the second reference point cloud including the one or more first three-dimensional points including the position information uncorrected; and encoding position information of the current three-dimensional point by reference to at least part of position information of the prediction point.

Abstract: The communication apparatus comprises a receiver which, in operation, receives a PHY layer Data Unit that includes a duration field; Physical (PHY) layer circuitry which, in operation, issues a PHY-CCA (clear channel assessment) primitive parameter indicating bandwidth information on a busy or idle state for each subchannel within an operating bandwidth; and Media Access Control (MAC) circuitry which, in operation, updates a Network Allocation Vector (NAV) value based on the duration information and, in operation, determines busy/idle state of at least one subchannel, wherein the MAC circuitry, in operation, controls transmission of the HE TB PHY layer Data Unit based on the updated NAV value and the busy/idle state of the at least one subchannel, and controls the PHY circuitry to have the HE TB PHY layer Data Unit transmitted when the at least one subchannel is considered idle, regardless of whether the primary subchannel is busy or not.

Abstract: An encoder includes circuitry and memory. The circuitry, in operation, generates a first coefficient value by applying a CCALF (cross component adaptive loop filtering) process to a first reconstructed image sample of a luma component. The circuitry generates a second coefficient value by applying an ALF (adaptive loop filtering) process to a second reconstructed image sample of a chroma component. The circuitry generates a third coefficient value by adding the first coefficient value to the second coefficient value, and encodes a third reconstructed image sample of the chroma component using the third coefficient value. In the CCALF process, in response to a coordinate of the second reconstructed image sample being (x, y), coordinates of the first reconstructed image samples are (2x, 2y−1), (2x−1, 2y), (2x, 2y), (2x+1, 2y), (2x−1, 2y+1), (2x, 2y+1), (2x+1, 2y+1), and (2x, 2y+2).

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.
