Abstract: A three-dimensional data encoding method includes: parsing a first syntax to determine, for each of at least one prediction tree in a slice, whether inter prediction or intra prediction is to be performed on the prediction tree, the prediction tree containing at least one three-dimensional point; and parsing a second syntax to determine a motion compensation mode to be performed on the prediction tree when the inter prediction is to be performed on the prediction tree.

Abstract: In a terminal, a control unit decides a sequence used for an uplink control channel, in accordance with uplink control information, and a transmission unit transmits the uplink control information using the sequence. Here, the sequence is calculated using cell identification information that identifies the cell to which the terminal belongs, and subcell-specific information relating to at least one subcell included in the cell.

Abstract: A three-dimensional data encoding method includes: obtaining third point cloud data that is a combination of first point cloud data and second point cloud data, and includes geometry information of each of three-dimensional points included in the third point cloud data, and identification information indicating which of the first point cloud data and the second point cloud data each of the three-dimensional points belongs to; and generating encoded data by encoding the third point cloud data obtained. In the generating, identification information of each of the three-dimensional points is encoded as attribute information.

Abstract: A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts that encode transport data; a mapping part that performs such a mapping that encoded data sequentially formed by the encoding parts are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.

Abstract: A transmission device includes: a weighting synthesizer that generates a first precoded signal and a second precoded signal; a first pilot inserter that inserts a pilot signal into the first precoded signal; a phase changer that applies a phase change of i×Δλ to the second precoded signal, where i is a symbol number and an integer that is greater than or equal to 0; an inserter that inserts a pilot signal into the phase-changed second precoded signal; and a phase changer that applies a phase change to the phase-changed and pilot-signal-inserted second precoded signal. Δλ satisfies π/2 radians

Abstract: A three-dimensional data encoding method includes: generating an N-ary tree structure of three-dimensional points included in three-dimensional data, where N is an integer greater than or equal to 2; generating first encoded data by encoding a first branch using a first encoding process, the first branch having, as a root, a first node included in a first layer that is one of layers included in the N-ary tree structure; generating second encoded data by encoding a second branch using a second encoding process different from the first encoding process, the second branch having, as a root, a second node included in the first layer and different from the first node; and generating a bitstream including the first encoded data and the second encoded data.

Abstract: A station apparatus includes a receiver and a controller. The receiver, in operation, receives a Trigger frame allocating Random Access Resource Units (RA-RUs) over multiple bands. The Trigger frame includes a User Info field that comprises a Band Indication subfield for specifying a first band among the multiple bands, an RU Allocation subfield for indicating a first RA-RU of one or more contiguous RA-RUs in the first band, and a Number of RA-RU subfield for indicating a number of the contiguous RA-RUs minus one in the first band. The controller, in operation: sets a first Orthogonal Frequency Division Multiple Access (OFDMA) random access backoff (OBO) counter to 0 if an initial value of the first OBO counter is not larger than a number of eligible RA-RUs in the first band, which is a subset of contiguous RA-RUs in the Trigger frame; and randomly selects one of the eligible RA-RUs.

Abstract: A loss correction encoding device having an improved capability of loss correction using LDPC-CC includes a rearranging unit that rearranges information data contained in n information packets according to the constraint length Kmax and the encoding rate (q−1)/q of a check polynomial of the loss correction code used in a loss correction encoding unit. Specifically, the rearranging unit rearranges the information data in such a way that continuous Kmax×(q−1) pieces of information data after rearrangement are contained in different information packets. The rearranging unit distributes the information data to information blocks from n information packets, where n satisfies the formula Kmax×(q−1)≤n.

Abstract: An interval between a pinhole and a pinhole is set to a first interval at which a degree of superimposition of subject images captured through the corresponding pinholes falls within a predetermined range when an image of a subject located at a distance less than a predetermined distance from the multi-pinhole camera is captured. An interval between the pinhole and a pinhole is set to a second interval narrower than the first interval at which a degree of superimposition of subject images captured through the corresponding pinholes falls within a predetermined range when an image of the subject located at a distance equal to or more than the predetermined distance from the multi-pinhole camera is captured.

Abstract: An encoder includes circuitry and a memory coupled to the circuitry. The circuitry, in operation, determines whether or not a ternary split process of splitting a block into three sub blocks in a first direction parallel to a first longer side of the block is allowed by comparing a size of a second shorter side of the block to a minimum threshold value. The circuitry, responsive to the ternary split process being allowed, writes, into a bitstream, a split direction parameter indicative of a splitting direction. The circuitry, in operation, splits the block into a plurality of sub blocks in a direction indicated by the split direction parameter; and encodes the plurality of sub blocks. The minimum threshold value corresponds to a minimum size supported in a transform process.
