Abstract: A three-dimensional data encoding method includes: setting a hierarchical structure for items of geometry information of three-dimensional points included in point cloud data, the hierarchical structure having depths and layers each having one or more of the depths; encoding the items of geometry information on a per depth basis to generate items of first encoded data each for a different one of the depths; and generating a bitstream including items of second encoded data which are items of encoded data for respective layers, the items of second encoded data each including one or more items of first encoded data of one or more depths included in a layer corresponding to the item of second encoded data. The bitstream includes an item of first information indicating a data length of each of the items of second encoded data.

Abstract: A terminal apparatus includes a receiver and reception signal control circuitry. The receiver, in operation, receives a first downlink data signal transmitted from a first communication station and receives a second downlink data signal transmitted from a first communication station, the first downlink data signal and the second downlink data signal being received over a first downlink channel and a second downlink channel that are at least partially overlapped in time and frequency domain. The reception signal control circuitry, in operation, demodulates the received first downlink data signal and a second downlink data signal.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry determines whether to split a current luma virtual pipeline decoding unit (VPDU) into smaller blocks. When it is determined not to split the current luma VPDU into smaller blocks, the circuitry predicts a block of chroma samples without using luma samples. When it is determined to split the luma VPDU into smaller blocks, the circuitry predicts the block of chroma samples using luma samples. The circuitry encodes the block using the predicted chroma samples.

Abstract: The invention relates to an improved transmission protocol for uplink data packet transmission in a communication system. A receiver of a user equipment receives a Fast Retransmission Indicator, referred to as FRI. The FRI indicates whether or not a base station requests a retransmission of a previously transmitted data packet. A transmitter of the user equipment retransmits the data packet using the same redundancy version as already used for the previous transmission of the data packet.

Abstract: A decoding method is a decoding method of decoding a current block of a video from a bitstream. The decoding method includes: decoding, from the bitstream, a prediction mode indicator indicating whether bi/uni mixed prediction is to be performed for the current block; decoding, from the bitstream, two instances of motion information for the current block; and when the prediction mode indicator indicates that the bi/uni mixed prediction is to be performed for the current block, (i) for a first partition, performing first prediction using one of the two instances, the first partition being part of the current block, the first prediction being uni-prediction, and (ii) for a second partition, performing second prediction using both of the two instances, the second partition being part of the current block, the second prediction being bi-prediction.

Abstract: An encoder includes: circuitry; and memory coupled to the circuitry. The circuitry, in operation, stores a first parameter into a bitstream, the first parameter indicating, as a prediction mode, one of (i) a multiple prediction mode in which a prediction image is generated by overlapping an inter prediction image of a current block and an intra prediction image of the current block and (ii) one of a plurality of prediction modes including a non-rectangular mode in which a prediction image is generated for each non-rectangular partition in the current block, and encodes the current block according to the prediction mode.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry, in operation, generates a first coefficient value by applying a CCALF (cross component adaptive loop filtering) process to a first reconstructed image sample of a luma component, and generates a second coefficient value by applying an ALF (adaptive loop filtering) process to a second reconstructed image sample of a chroma component. The circuitry modifies the first coefficient value by performing an arithmetic right shift by 7 bits on the first coefficient value. The circuitry generates a third coefficient value by adding the modified first coefficient value to the second coefficient value, and encodes a third reconstructed image sample of the chroma component using the third coefficient value.

Abstract: An encoder which encodes a video including a plurality of pictures includes circuitry and memory. Using the memory, the circuitry performs: encoding a first picture among the plurality of pictures; and performing (i) a first operation for encoding a parameter set for a second picture which follows the first picture in coding order among the plurality of pictures after encoding the first picture, and encoding the second picture after encoding the parameter set, or (ii) a second operation for encoding the second picture without encoding the parameter set after encoding the first picture. The circuitry performs the first operation when the second picture is a determined picture, in the performing of the first operation or the second operation.

Abstract: A three-dimensional data encoding method includes: encoding geometry information of each of three-dimensional points based on one of a first geometry information encoding method of encoding using octree division and a second geometry information encoding method of encoding without using octree division; and generating a bitstream including the geometry information encoded and a geometry information flag indicating whether the encoding was performed based on the first geometry information encoding method or the second geometry information encoding method. In the generating of the bitstream: when the encoding is performed based on the first geometry information encoding method, the bitstream including a parameter set used in octree division is generated; and when the encoding is performed based on the second geometry information encoding method, the bitstream not including the parameter set used for octree division is generated.
