Abstract: A three-dimensional data encoding method includes: dividing a current frame including three-dimensional points into processing units; and encoding the processing units to generate a bitstream. Control information for each frame included in the bitstream includes first information indicating whether (i) one of the processing units included in the current frame includes duplicated points that are three-dimensional points having same geometry information or (ii) none of the processing units includes the duplicated points.

Abstract: An encoder includes circuitry and memory. The circuitry, using the memory: prohibits a first splitting method when arrangement and shapes of blocks obtained by splitting a first block multiple times by the first splitting method are identical to arrangement and shapes of blocks obtained by splitting the first block multiple times by a second splitting method different from the first splitting method, and when scan order of the blocks obtained by the first splitting method is identical to scan order of the blocks obtained by the second splitting method; and encodes the first block.

Abstract: The layer processing includes at least processing on a first, a second and a third layer. At the transmitter side, the third layer receives a packet, adds its header and forwards the packet to the second layer. The second layer performs segmentation and provides segmented data to the first layer, which maps the segmented data onto physical resources. The segmentation is based on the allocated resources. Retransmissions may take place on the third layer and thus, the third layer may re-segment the packet according to the received feedback for particular segments and provide the re-segmented data to the lower layers. Alternatively, the feedback information is provided to the second layer which then performs the segmentation by taking it into account. Correspondingly, the receiver performs re-ordering and re-assembly at the third layer for which it receives also control information from the second layer.

Abstract: An encoder includes circuitry and memory connected to the circuitry. In operation, the circuitry corrects a base motion vector using a correction value in a fixed direction; and encodes a current partition by using the corrected base motion vector corrected. The correction value is specified by an index indicating one of correction values included in a table. The table is selected from among a plurality of tables, wherein the correction values in one of the plurality of tables have different increments from the correction values in another one of the plurality of tables.

Abstract: A three-dimensional data encoding method includes: generating a bitmap indicating which of pieces of three-dimensional data a three-dimensional point belongs to, the three-dimensional point being included in a unit space; generating a conversion code using a look-up table and the bitmap generated; and generating encoded data including duplicated point information indicating a total number of three-dimensional points included in the unit space, and conversion code information indicating the conversion code. The generating of the conversion code includes: generating the conversion code from the bitmap when the total number of the three-dimensional points included in the unit space is less than or equal to a predetermined threshold value; and generating the conversion code from an inverted bitmap when the total number of the three-dimensional points included in the unit space is greater than the predetermined threshold value, the inverted bitmap being obtained by inverting 0 and 1 included in the bitmap.

Abstract: The present invention provides a terminal capable of suitably performing random access processing. In a terminal (100), a RACH resource determination unit (104) determines the format of a random access signal on the basis of a parameter related to the transmission of the random access signal, which includes a preamble part and a data part. A wireless transmission unit (109) transmits the random access signal on the basis of the format.
