Abstract: An encoder includes circuitry and memory connected to the circuitry. In operation, the circuitry: stores MV information and correction processing information into a FIFO buffer for an HMVP mode in association, the MV information being derived for a processed block and correction processing information being related to correction processing of a prediction image of the processed block; registers, in a prediction candidate list for a merge mode, one or more prediction candidates each being a combination of MV information and correction processing information, the prediction candidates including a prediction candidate which is a combination of the motion vector information and the correction processing information stored in the FIFO buffer; and selects a prediction candidate from the prediction candidate list when a current block is to be processed in the merge mode, and performs correction processing of a prediction image of the current block, based on the correction processing information.

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: An encoder encodes a video, and includes: circuitry; and memory coupled to the circuitry. Using the memory, the circuitry: obtains at least two items of prediction information for a first partition included in the video; derives at least one template from neighboring samples which neighbor the first partition; calculates at least two costs, using the at least one template and the at least two items of prediction information; using the at least two costs, (i) determines at least one splitting direction for the first partition or (ii) assigns one of the at least two items of prediction information to a second partition split from the first partition according to the splitting direction, and another thereof to a third partition split from the first partition according to the splitting direction; and encodes the first partition according to the splitting direction and the at least two items of prediction information.

Abstract: A communication apparatus includes circuitry and a transmitter. The circuitry generates a signal including one or more non-legacy long training field (LTF) symbols. Each of the one or more non-legacy LTF symbols has a plurality of data tones and a plurality of pilot tones. The circuitry maps a non-legacy LTF sequence to the plurality of data tones and the plurality of pilot tones, and groups the plurality of data tones with nonzero non-legacy LTF sequence values into a first tone group and a second tone group. The signal includes information on a number NSTS of space-time streams, wherein a total number of the one or more non-legacy LTF symbols is [NSTS/2] when 10 the NSTS is 2, 3, 4, 7, 8, 11, 12, 15 or 16; and [NSTS/2]+1 when the NSTS is 5, 6, 9, 10, 13 or 14. The transmitter, in operation, transmits the generated signal.

Abstract: There are provided an apparatus, a method and a system. The apparatus comprises: a transmitter operative to transmit wireless data or signals to a second node; and a circuitry operative to determine whether one or more reserved periods are reserved between two continuous data or signals transmitted by the transmitter based on a length of configured transmission time intervals (TTIs), wherein the circuitry is further operative to: determine the one or more reserved periods are reserved between two continuous data or signals in a case that the length of configured TTI is shorter than or equal to a threshold.
