Abstract: A terminal includes circuitry and a transmitter. The circuitry, in operation, determines a first transmission power for a first uplink signal and a second transmission power for a second uplink signal by prioritizing allocation of a transmission power to the second transmission power for the second uplink signal, responsive to, in a first transmission time interval (TTI) where the first uplink signal is transmitted, the second uplink signal being transmitted in a second TTI that is shorter than the first TTI. The transmitter, in operation, transmits the first uplink signal with the determined first transmission power and transmits the second uplink signal with the determined second transmission power.

Abstract: An encoder includes circuitry and memory connected to the circuitry, and the circuitry, in operation: determines, based on a width and a height of a block, whether or not to disable a prediction mode in which the block is split along a partitioning line defined by a distance and an angle and then prediction is performed; and encodes the block with the prediction mode disabled or not disabled according to a result of the determination on whether or not to disable the prediction mode. Here, the distance is the shortest distance between the center of the block and the partitioning line, and the angle is an angle representing a direction from the center of the block toward the partitioning line in the shortest distance. The circuitry determines to disable the prediction mode when (i) a width-to-height ratio is at least 8 or (ii) a height-to-width ratio is at least 8.

Abstract: A transmitting method includes: configuring a frame using a plurality of orthogonal frequency-division multiplexing (OFDM) symbols, by allocating a plurality of transmission data to a plurality of areas; and transmitting the frame. The plurality of areas are each identified by at least one time resource among resources and at least one frequency resource among frequency resources. The frame includes a first period in which a preamble is transmitted, and a second period in which the plurality of transmission data are transmitted by at least one of time division and frequency division. The second period includes a first area, and the first area includes a data symbol generated from first transmission data, a data symbol generated from second transmission data and subsequent to the data symbol generated from the first transmission data, and a dummy symbol subsequent to the data symbol generated from the second transmission data.

Abstract: In the information processing method, first data is input into a discriminator to obtain first discrimination result data; second data is input into the discriminator to obtain second discrimination result data; a first difference between reference data and the first discrimination result data is calculated; a first squared error data and a first weight are calculated based on the first difference; a second difference between reference data and the second discrimination result data is calculated; a second squared error data and a second weight are calculated based on the second difference; and the discriminator is trained based on the first squared error data, the second squared error data, the first weight, and the second weight. The first discrimination result data and the second discrimination result data are data of a tensor having a rank of one or higher.

Abstract: An information processing device in a first vehicle: detects a head-on approach of a second vehicle relative to the first vehicle; determines whether a meeting point is in a first section; calculates a first distance between the first section and the meeting point; when the meeting point is not in the first section, transmits the first distance to the second vehicle, and receives, from the second vehicle, a second distance between the meeting point and a second section; generates travel control information for the first vehicle according to the result of comparison between the first distance and the second distance; and outputs the travel control information to a travel controller of the first vehicle.

Abstract: In a multi-antenna communication system using LDPC codes, a simple method is used to effectively improve the received quality by performing a retransmittal of less data without restricting applicable LDPC codes. In a case of a non-retransmittal, a multi-antenna transmitting apparatus (100) transmits, from two antennas (114A,114B), LDPC encoded data formed by LDPC encoding blocks (102A,102B). In a case of a retransmittal, the multi-antenna transmitting apparatus (100) uses a transmission method, in which the diversity gain is higher than in the previous transmission, to transmit only a part of the LDPC encoded data as previously transmitted. For example, the only the part of the LDPC encoded data to be re-transmitted is transmitted from the single antenna (114A).

Abstract: An encoder includes circuitry and memory connected to the circuitry. In operation, the circuitry: corrects a base motion vector using a correction value for correcting the base motion vector in a predetermined direction; and encodes a current partition to be encoded in an image of a video, using the base motion vector corrected. The correction value is specified by a first parameter and a second parameter, the first parameter indicating a table to be selected from among a plurality of tables each including values, the second parameter indicating one of the values included in the table to be selected indicated by the first parameter. In each of the plurality of tables, a smaller value among the values is assigned a smaller index. Each of the plurality of tables includes a different minimum value among the values.
