Abstract: Disclosed are an encoder, a transmission device, and an encoding method with which the transmission amount is reduced and a deterioration in transmission efficiency is suppressed while improving reception quality when QC-LDPC or a like block encoding is used. A puncture pattern setting unit (620) searches for a puncture pattern for each integral multiple of the number of columns or for each divisor of the number of columns of a sub block matrix that forms a check matrix (H) of a QC-LDPC code, and a puncture unit (data reduction unit) (630) switches the puncture pattern for each integral multiple of the number of columns or for each divisor of the number of columns of the sub block matrix that forms the check matrix of the QC-LDPC code.

Abstract: A terminal with which it is possible to appropriately transmit uplink control information. In a terminal (200), a reception unit (202) receives first control information relating to an uplink data channel, and a second control information relating to an uplink control channel for transmitting uplink control information. The first control information includes first indication information indicating the presence or absence of an uplink data transmission and second indication information indicating the presence or absence a channel state information transmission. A transmission unit (220) transmits uplink control information using the resource of the uplink data channel when the first indication information indicates that there is no uplink data transmission and the second indication information indicates that there is no channel state information transmission.

Abstract: An aerosol quantity estimation method includes: determining whether a sound pressure level of a spoken voice of a speaker is higher than a predetermined sound pressure level; calculating an acoustic feature from speech data of the spoken voice of the speaker when the sound pressure level of the spoken voice is higher than the predetermined sound pressure level; calculating a first speaker feature from the acoustic feature by using a trained model, the first speaker feature representing a speaker characteristic of the speech data; calculating a similarity between the first speaker feature and a second speaker feature that is a speaker feature of the speaker when in a calm state; and estimating a quantity of aerosols generated by the speaker, the quantity of aerosols corresponding to the similarity.

Abstract: An encoder includes: circuitry; and memory coupled to the circuitry. In operation, the circuitry: controls whether to change a resolution of a picture from a resolution of a previous picture preceding the picture in one of display order and encoding order, according to a constraint that allows the changing only when the picture is a random access picture among one or more random access pictures; and when a resolution of a reference picture to be used in encoding of an inter-predicted picture is different from a resolution of the inter-predicted picture, resamples a reference image in the reference picture according to a difference between the resolution of the reference picture and the resolution of the inter-predicted picture, and encodes an image in the inter-predicted picture using the reference image resampled.

Abstract: An encoder: generates, in an inter prediction mode, a first prediction image of a current block to be processed, based on a derived motion vector; and generates a final prediction image of the current block by applying an update process to the first prediction image. Candidates for the update process include a first process and a second process. The first process is a BDOF process. The second process is a process of mixing the first prediction image with a second prediction image generated in intra prediction for the current block. In the applying of the update process, the first process and the second process are mutually exclusively applied.
