Abstract: This terminal comprises: a reception circuit that receives control information corresponding to a downlink message in a random access procedure; and a control circuit that determines a setting for the repeated transmission of an uplink control signal for the downlink message, on the basis of a value of a field related to a setting different from the setting for the repeated transmission, in the control information.

Abstract: An encoder includes circuitry and memory. Using the memory, the circuitry performs prediction on an image. A motion vector predictor list used in the prediction includes a spatially neighboring motion vector predictor obtained from a block spatially neighboring a current block, and a spatially broad motion vector predictor obtained from a block positioned at any of a plurality of predetermined positions in a second range that is broader than a first range that spatially neighbors the current block. The plurality of predetermined positions are defined by a regular interval using the top-left of a current picture as a reference point.

Abstract: A decoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry: decodes a plurality of sets of neural network information each of which identifies a neural network filter; decodes, from one access unit, two or more sets of activation information each of which specifies one set of neural network information among the plurality of sets of neural network information; and applies, to one picture, two or more neural network filters identified by two or more sets of neural network information specified by the two or more sets of activation information.

Abstract: A three-dimensional data encoding method of encoding three-dimensional points each having an attribute information item includes: classifying each of the three-dimensional points into any of layers including a first layer and a second layer; and arithmetic-encoding an attribute information item of a current three-dimensional point among the three-dimensional points with reference to a first encoding table when the current three-dimensional point is at the first layer, and with reference to a second encoding table not dependent on the first encoding table when the current three-dimensional point is at the second layer.

Abstract: An encoder includes circuitry and memory. Using the memory, the circuitry, in operation, selects an encoding mode from among candidates including a decoder-side motion vector refinement (DMVR) encoding mode and a partition encoding mode. When the DMVR encoding mode is selected, the circuitry: obtains a first motion vector for a first image block; derives a second motion vector from the first motion vector using motion search; and generates a prediction image for the first image block using the second motion vector. When the partition encoding mode is selected, the circuitry: determines a plurality of partitions in a second image block; obtains a third motion vector for each partition; and generates a prediction image for the second image block using the third motion vector, without deriving a fourth motion vector from the third motion vector using motion search.

Abstract: An encoder includes circuitry which generates a first coefficient value by applying a CCALF process to a first reconstructed image sample of a luma component; generates a second coefficient value by applying an ALF process to a second reconstructed image sample of a chroma component; 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. The circuitry writes a first parameter into a sequence parameter set; writes a second parameter into a parameter set of a picture in response to a value of the first parameter being 1; writes a third parameter into a slice header in response to the value of the first parameter being 1; and writes a fourth parameter into a coding tree unit in response to a value of the third parameter being 1.

Abstract: A three-dimensional data encoding method includes: assigning three-dimensional points to one of layers, based on items of geometry information of the three-dimensional points; searching three-dimensional points surrounding a current three-dimensional point to be encoded, to select, from the three-dimensional points, a three-dimensional point to be referred to when a predicted value of attribute information of the current three-dimensional point is calculated, the current three-dimensional point belonging to a first layer among the layers; and calculating the predicted value of the attribute information of the current three-dimensional point using the three-dimensional point selected. In the searching of the three-dimensional points, a search range for a same layer as the current three-dimensional point is different from a search range for a layer higher than the first layer.
