Abstract: An encoder includes circuitry and memory connected to the circuitry. In operation, the circuitry: stores MV information and correction processing information into a FIFO buffer for an HMVP mode in association, the MV information being derived for a processed block and correction processing information being related to correction processing of a prediction image of the processed block; registers, in a prediction candidate list for a merge mode, one or more prediction candidates each being a combination of MV information and correction processing information, the prediction candidates including a prediction candidate which is a combination of the motion vector information and the correction processing information stored in the FIFO buffer; and selects a prediction candidate from the prediction candidate list when a current block is to be processed in the merge mode, and performs correction processing of a prediction image of the current block, based on the correction processing information.

Abstract: An image decoder performs a first partitioning including using a first partition mode, without parsing first splitting information indicative of the first partition mode, to split a first block into a plurality of second blocks in response to that the first block is located adjacent to an edge of a picture and that the dimensions of the first block satisfy a first condition; and performs a second partitioning on the second block by parsing second splitting information indicative of a second partition mode, wherein the second partition mode allows at least one of a quad tree splitting and a binary splitting, and using the second partition mode to split the second block into a plurality of coding units (CUs), wherein the second partition mode prohibits the quad tree splitting of the second block in response to that the second block is located adjacent to the edge of the picture.

Abstract: A three-dimensional data encoding method includes: encoding nodes in an N-ary tree structure of a current three-dimensional point cloud, N being an integer greater than or equal to 2; and generating a bitstream including the nodes encoded. In the encoding: at least one node among the nodes is encoded using an inter prediction mode in which a reference three-dimensional point is referred to; and at least one other node among the nodes is encoded using an intra prediction mode in which the reference three-dimensional point is not referred to, the at least one other node being other than the at least one node. The bitstream further includes information which distinguishes between the at least one other node and the at least one node.

Abstract: A resource assignment determiner determines a resource for a PDSCH intended for an MTC terminal, and a transmitter transmits an MPDCCH that includes resource assignment bits indicating the resource thus determined and transmits the PDSCH using the resource thus determined. The MPDCCH is a PDCCH intended for the MTC terminal. The resource assignment bits are associated with a resource that is used when the MPDCCH and the PDSCH are transmitted in the same subframe and a resource that is used when the MPDCCH and the PDSCH are transmitted in different subframes.
