Abstract: A three-dimensional data encoding method includes: encoding geometry information of a three-dimensional point included in point cloud data, using a prediction tree, to generate encoded geometry information; and encoding information indicating a child node count, which is a total number of child nodes of a node included in the prediction tree, to generate encoded child node count information. The encoded child node count information is represented by a bit count corresponding to the child node count, and when the child node count is 1, the encoded child node count information is represented by a lowest bit count.

Abstract: An encoder includes circuitry and a memory coupled to the circuitry, wherein the circuitry, in operation, performs a partition process. The partition process includes calculating first values of a set of pixels between a first partition and a second partition in a current block, using a first motion vector for the first partition; calculating second values of the set of pixels, using a second motion vector for the second partition; and calculating third values of the set of pixels by weighting the first values and the second values. When a ratio of a width to a height of the current block is larger than 4 or a ratio of the height to the width of the current block is larger than 4, the circuitry disables the partition process.

Abstract: An encoder includes processing circuitry and a memory coupled to the processing circuitry. The processing circuitry is configured to: select a filter based at least on a prediction mode used for a first block, the filter including first filter coefficients for the first block and second filter coefficients for a second block; multiply values of first pixels among the first block and second pixels among the second block by the first filter coefficients to change a value of a first pixel in the first pixels; and multiply the values of the first pixels among the first block and the second pixels among the second block by the second filter coefficients to change a value of a second pixel in the second pixels.

Abstract: Provided are a base station device and a mobile station device, which can lighten a cell-search processing. The base station device includes a frame constitution unit for forming a frame, in which a pilot symbol multiplied by a base station scrambling code and a plurality of sequences contained in the corresponding sequence set is arranged in at least the head or tail, and a radio transmission unit for sending the formed frame. On the receiving side, the frame timing can be detected from the position of a pilot symbol contained in that frame. Since the base station scrambling code and the sequence set containing the sequences are made to correspond to each other, candidates can be narrowed to at most the base station scrambling codes of the number of the combinations of the sequences contained in the sequence set, by detecting the sequences multiplied by the pilot symbol.
