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: The present disclosure relates to a user equipment, a network node and respective communication methods for a user equipment and a network node. A according to some embodiments, a user equipment comprises a transceiver which, in operation, receives data on a plurality of downlink shared channels, the data received on the plurality of downlink shared channels being respectively the same data, and circuitry which, in operation, decodes the data, generates an indicator which indicates whether or not the data has been successfully decoded using the plurality of downlink shared channels. The transceiver, in operation, transmits the indicator on at least one of a plurality of uplink control channels associated respectively with the plurality of downlink shared channels.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry: encodes one or more pictures which have common time information and each of which is included in a different layer; adds the one or more pictures into one access unit in a bitstream; and adds, into the bitstream, a first flag indicating that a total number of access units present in the bitstream is one.

Abstract: An encoder partitions into blocks using a set of block partition modes. The set of block partition modes includes a first partition mode for partitioning a first block, and a second block partition mode for partitioning a second block which is one of blocks obtained after the first block is partitioned. When the number of partitions of the first block partition mode is three, the second block is a center block among the blocks obtained after partitioning the first block, and the partition direction of the second block partition mode is same as the partition direction of the first block partition mode, the second block partition mode indicates that the number of partitions is only three. A parameter for identifying the second block partition mode includes a first flag indicating a horizontal or vertical partition direction, and does not include a second flag indicating the number of partitions.
