Abstract: In a terminal, in a slot having allocated thereto both an uplink control channel (PUCCH) and an uplink channel (PUSCH) that includes uplink data, in a case where the difference between the power spectrum density (PSD) of the PUCCH and the PSD of the PUSCH is greater than a threshold value (permitted difference), a control unit drops symbols of the PUSCH in a transmission interval for the PUSCH overlapping with a transmission interval for the PUCCH. A transmission unit transmits at least the PUCCH in the slot.

Abstract: An image encoder includes circuitry and a memory, wherein the circuitry, in operation, determines whether inter prediction is to be applied to a current block; in response to determining that the inter prediction is to be applied to the current block, performs a partition prediction process; and, in response to determining that the inter prediction is not to be applied, encodes the current block without using the partition prediction process. The partition prediction process includes predicting first values of a set of pixels between a first partition and a second partition in the current block, using a first motion vector for the first partition; predicting second values of the set of pixels, using a second motion vector for the second partition; weighting the first values and the second values; and generating a prediction image for the current block using the weighted first values and the weighted second values.

Abstract: A three-dimensional point cloud generation method for generating a three-dimensional point cloud including one or more three-dimensional points includes: obtaining (i) a two-dimensional image obtained by imaging a three-dimensional object using a camera and (ii) a first three-dimensional point cloud obtained by sensing the three-dimensional object using a distance sensor; detecting, from the two-dimensional image, one or more attribute values of the two-dimensional image that are associated with a position in the two-dimensional image; and generating a second three-dimensional point cloud including one or more second three-dimensional points each having an attribute value, by performing, for each of the one or more attribute values detected, (i) identifying, from a plurality of three-dimensional points forming the first three-dimensional point cloud, one or more first three-dimensional points to which the position of the attribute value corresponds, and (ii) appending the attribute value to the one or more first three-dimensional points identified.

Abstract: The present disclosure provides a communication apparatus and a communication method for allocating one or more additional operating windows for a reception or a transmission of a sidelink signal. The communication apparatus comprises circuitry which, in operation, is configured to allocate one or more additional operating windows between a first operating window and a second operating window for a reception or a transmission of a sidelink signal, and a transceiver which, in operation, transmit or receive a sidelink signal within the one or more additional operating window.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. Given id indicating a lower temporal sublayer other than a highest temporal sublayer in temporal sublayers, the circuitry calculates a DPB output time [id] for a picture in the lower temporal sublayer. In doing so, the circuitry of the encoder subtracts a DPB output delta [id] provided for each of the temporal sublayers from a DPB output delay shared between the temporal sublayers, and given maxid indicating the highest temporal sublayer, calculates the DPB output delta [id] by subtracting a CPB removal delay [maxid] and an offset [id] from a CPB removal delay [id]. Next, the circuitry stores the offset [id] in a bitstream.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. In residual coding of a current block, the circuitry, in operation, encodes a subblock flag by Context-based Adaptive Binary Arithmetic Coding (CABAC) in both of a first type of residual coding where an orthogonal transform is performed and a second type of residual coding where the orthogonal transform is skipped, the subblock flag indicating whether a non-zero coefficient is included in a plurality of coefficients for a subblock within the current block, wherein a first syntax used for the first type of residual coding is different from a second syntax used for the second type of residual coding; and controls a number of CABAC processes, wherein the encoding of the subblock flag is not counted as the number of CABAC processes.

Abstract: A transmitting method stores data making up a coded stream into a predetermined data unit and transmits the stored data in the predetermined data unit. The transmitting method further generates presentation time information indicating a presentation time of the predetermined data unit, based on reference time information received from an external source; and transmits the predetermined data unit, first control information which includes the generated presentation time information, and second control information which includes leap second information indicating whether or not the presentation time information is a time that is before a leap second adjustment. A receiving method receives the predetermined data unit, first control information, and second control information; and reproduces the received predetermined data unit based on the first and second control information that are received.
