Abstract: An encoder 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 encoder 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: 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 communication device (100) comprises: a circuit (11) that sets a first value to an association ID (AID) 12 subfield of the first field of a trigger frame requesting an extremely high throughput (EHT) trigger-based (TB) physical layer protocol data unit (PPDU); and a transmitter (12) that transmits the trigger frame. The first value indicates that the first field contains information to be shared for the transmission of the EHT TB PPDU.

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: The present disclosure relates to a user equipment (UE), comprising the following. A processor of the UE operates a paging function that includes monitoring of a downlink control channel for receiving a paging downlink control information, DCI, and includes receiving of a paging message, the paging DCI and the paging message being transmitted from a base station. A receiver of the UE receives paging sub-group signalling from the base station. The processor determines a paging sub-group index based on the received paging sub-group signalling. The processor determines how to operate the paging function based on whether or not the determined paging sub-group index fulfils a requirement that involves an identification of the UE.

Abstract: The present invention provides a transmitter which can suitably perform a transmission power control in a PT-RS port. In this transmitter (100), a control unit (101) determines a transmission power for transmitting a reference signal (PT-RS) for phase tracking and a data signal within a range in which the maximum transmission power for each antenna port is not exceeded. In addition, a transmission unit (105) transmits the reference signal for phase tracking and the data signal at the transmission power determined by the control unit (101).

Abstract: A log generation method for generating a log of communication on an in-vehicle network includes: performing a plurality of determination processes for determining, by using different methods, whether or not a message sent to the in-vehicle network is anomalous; generating a log in accordance with results of the plurality of determination processes; and transmitting the generated log. In the generating, information items to be included in the log are determined in accordance with a combination of the results of the plurality of determination processes so that the log does not include identical information items.
