Abstract: The present disclosure relates to a transmission device, a reception device, a transmission method and a reception method. The transmission device comprises a circuitry which, in operation, maps data and/or a reference signal onto a resource unit of a communication system. The resource unit includes subcarriers of a first numerology and subcarriers of a second numerology, each of the subcarriers being orthogonal to the other subcarriers of the same numerology, wherein the first numerology differs from the second numerology at least by a larger subcarrier spacing, and the subcarriers of the first and the second numerologies are frequency-multiplexed on a subcarrier basis. The transmission device further comprises a transmitter which, in operation, transmits the mapped data and/or reference signal in the resource unit, including subcarriers of the first and/or of the second numerology, and also transmits an indication of the mapping for the resource unit, which comprises references to subcarriers from the subcarriers of the first and/or the second numerology, where: for the first numerology, all subcarriers of the resource unit can be referenced, and for the second numerology, only inter-numerology-orthogonal subcarriers thereof can be referenced, each of the inter-numerology-orthogonal subcarriers being centrally aligned with a subcarrier of the first numerology.

Abstract: A drone includes a light emitter that emits light and circuitry which, in operation, obtains flight state information regarding a flight state of the drone, determines, on the basis of the flight state information, a direction in which the light emitter is to emit light, and controls the light emitter such that the light emitter emits light in the determined direction.

Abstract: A base station selects, from among a plurality of code sequences orthogonal to one another, one code sequence by which an uplink signal including a demodulation reference signal repeated in a plurality of subframes is multiplied and transmits, to a terminal for which transmission of the repeated uplink signal is configured, information indicating the selected code sequence by using a field for indicating a cyclic shift and an orthogonal sequence used for the demodulation reference signal. A terminal receives information indicating one of a plurality of code sequences orthogonal to one another using a field for indicating a cyclic shift and an orthogonal sequence used for a demodulation reference signal and multiplies an uplink signal including the demodulation reference signal repeated in a plurality of subframes by the code sequence indicated by the information.

Abstract: A three-dimensional data encoding method of encoding three-dimensional points includes: calculating a new predicted value as a predicted value, using attribute information items of one or more second three-dimensional points neighboring a first three-dimensional point, and assigning the predicted value to at least one prediction mode among two or more prediction modes, the new predicted value being used for calculating an attribute information item of the first three-dimensional point; selecting one prediction mode from the two or more prediction modes; calculating a prediction residual which is a difference between the attribute information item of the first three-dimensional point and the predicted value of the one prediction mode selected; and generating a bitstream including the one prediction mode and the prediction residual.

Abstract: A non-transitory tangible recording medium stores recorded AV data. The AV data includes a system stream file played by a playback device and a management information file having management information corresponding to the system stream file. The system stream file includes a first segment including repeated a first data unit that be decrypted using a first decryption key that the playback device individually has and a second data unit that cannot be decrypted by the first decryption key. The system stream file also includes a second segment which can be decrypted using a second decryption key that the playback device has in common with another playback device. The management information file has a start source packet number, which identifies a start source packet out of a plurality of source packets storing an I-picture that is a random access point, and the start source packet is situated in the second segment.

Abstract: A three-dimensional data encoding method includes: transforming pieces of attribute information of three-dimensional points included in point cloud data into coefficient values; and encoding the coefficient values to generate a bitstream. In the transforming, weighting calculation is performed hierarchically to generate the coefficient values belonging to one of layers, the weighting calculation separating each of the pieces of attribute information into a high-frequency component and a low-frequency component. In the weighting calculation, the weighting calculation is performed using weights fixed or not fixed in the layers. The bitstream includes first information indicating whether to fix the weights in the layers.
