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: Executing a deep neural network by obtaining, during deep neural network inference, a binary intermediate feature map in binary representation by converting a floating-point or fixed-point intermediate feature map into a binary vector using a first transformation module; generating a compressed feature map by compressing the binary intermediate feature map using a nonlinear dimensionality reduction layer; storing the compressed feature map into memory; reconstructing the binary intermediate feature map by decompressing the compressed feature map read from the memory using a reconstruction layer corresponding to the nonlinear dimensionality reduction layer; and converting the reconstructed binary intermediate feature map into a floating-point or fixed-point intermediate feature map using a second transformation module.

Abstract: The present disclosure relates to a user equipment (UE) that comprises a processor that operates a monitoring function that involves monitoring of a downlink control channel of an unlicensed radio cell based on one of a plurality of groups of search space sets (SSS). The unlicensed radio cell operates in an unlicensed spectrum and is controlled by a base station that is in communication with the user equipment. Further, one of the plurality of groups of SSSs is configured to be a default group of SSSs. The processor determines one group of the plurality of SSS groups for performing the monitoring function, depending on the downlink control channel. The monitoring function is not performed during a non-monitoring time period. The processor determines to perform the monitoring function based on the default group of SSSs, when performing the monitoring function subsequent to the non-monitoring time period.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry switches between storing and not storing of a decoded picture buffer (DPB) parameter related to a DPB in a common header shared between layers in layer groups each including at least one output layer, according to whether or not all the layer groups in a bitstream each include only one layer.

Abstract: A three-dimensional data encoding method includes: performing a conversion process including a displacement on, out of first point cloud data and second point cloud data having a same time, the second point cloud data, and combining the first point cloud data and the second point cloud data after being subjected to the conversion process, to generate third point cloud data; and encoding the third point cloud data to generate a bitstream. The bitstream includes first information and second information, the first information indicating to which of the first point cloud data and the second point cloud each of three-dimensional points included in the third point cloud data belongs, the second information indicating details of the displacement.

Abstract: Modulated signal A is transmitted from a first antenna, and modulated signal B is transmitted from a second antenna. As modulated signal B, modulated symbols S2(i) and S2(i+1) obtained from different data are transmitted at time i and time i+1 respectively. In contrast, as modulated signal A, modulated symbols S1(i) and S1(i)′ obtained by changing the signal point arrangement of the same data are transmitted at time i and time i+1 respectively. As a result the reception quality can be changed intentionally at time i and time i+1, and therefore using the demodulation result of modulated signal A of a time when the reception quality is good enables both modulated signals A and B to be demodulated with good error rate performances.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry determines whether or not a current video to be processed is a progressive video. When it is determined that the current video is a progressive video, the encoder encodes, into a bitstream, one syntax element indicating a chroma location type which is information indicating locations of chroma samples relative to luma samples for a frame included in the current video. When it is determined that the current video is not a progressive video, the encoder encodes two syntax elements into the bitstream, each of which indicates the chroma location type for a different one of fields of two types included in the current video.
