Abstract: The present disclosure provides communication apparatus and communication method for transmission over combinations of multiple resource units. The communication apparatus comprises: circuitry, which, in operation, generates a physical layer protocol data unit (PPDU) comprising a signal field and a data field, the signal field comprising a resource unit (RU) allocation field and one or more user specific field and the data field comprising one or more physical layer service data unit (PSDU); and a transmitter which, in operation, transmits the generated PPDU, wherein a single PSDU of the one or more PSDU is transmitted over a RU combination, and whether two or more RUs of the RU combination share a single low density parity check tone mapper depends on the size of the two or more RUs of the RU combination.

Abstract: Various embodiments provide an encoder that performs an up-conversion and a down-conversion on a first quantization matrix to generate a second quantization matrix, and quantizes transform coefficients of a current block using the second quantization matrix. The first quantization matrix has a first number of rows and a first number of columns equal to the first number of rows, and the second quantization matrix has a second number of rows and a second number of columns different from the second number of rows. In the up-conversion, the circuitry generates the second quantization matrix such that one of the second number of rows or the second number of columns is larger than the first number of rows. In the down-conversion, the circuitry generates the second quantization matrix such that the other of the second number of rows or the second number of columns is smaller than the first number of rows.

Abstract: A video decoding device, in the case where a video of the progressive format is inputted, processes a frame as a picture, in the case where a video of the interlace format is inputted, processes a field as a picture. A video decoding device performs display control corresponding to a format of the both video by analyzing display control information in display control information analyzer. The display control information includes sequence unit display control information which is commonly used in a display process of all pictures that belong to a sequence to be decoded and picture unit display control information which is individually used in a display process of a picture to be decoded. A second code string analyzer acquires each of the sequence unit display control information and the picture unit display control information from an extended information area in units of pictures.

Abstract: Provided are an eNB, a UE and wireless communication methods. The eNB, in an embodiment, includes circuitry operative to fill a SPS activation/deactivation field in a DCI with a predetermined pattern of bits; and a transmitter operative to transmit the DCI to a first UE for the first UE to start periodically transmitting signals to a second UE or stop periodically transmitting signals to the second UE based on the SPS activation/deactivation field. The DCI is in a SPS format formed by adopting part or all bits of at least one field of DCI format 5 as the SPS activation/deactivation field, and information supposed to be transmitted in the at least one field is indicated with the assistance of or by RRC or MAC signaling.

Abstract: A three-dimensional data encoding method includes: generating a bitstream by encoding subspaces included in a current space in which three-dimensional points are included. The bitstream includes encoded data respectively corresponding to the subspaces. In the generating of the bitstream, a list of information about the subspaces is stored in first control information included in the bitstream. The subspaces are respectively associated with identifiers assigned to the subspaces, and the first control information is common to the encoded data. Each of the identifiers assigned to the subspaces respectively corresponding to the encoded data is stored in a header of a corresponding one of the encoded data.

Abstract: A method for use of a wireless terminal device includes transmitting a Probe request frame by using a quasi-omni antenna pattern in a first channel if beam-forming training with a wireless base station device is not completed, selecting the wireless base station device as a connection destination if a Probe response frame corresponding to the Probe request frame is received from the wireless base station device, and performing the beam-forming training with the wireless base station device in a second channel if a time period for receiving the Probe response frame from the wireless base station device has passed.

Abstract: An encoder which includes circuitry and memory. Using the memory, the circuitry generates a list which includes candidates for a first motion vector for a first partition. The list has a maximum list size and an order of the candidates, and at least one of the maximum list size or the order of the candidates is dependent on at least one of a partition size or a partition shape of the first partition. The circuitry selects the first motion vector from the candidates included in the list; encodes an index indicating the first motion vector among the candidates in the list into the bitstream based on the maximum list size; and generates the predicted image for the first partition using the first motion vector.

Abstract: A repetition unit (212) performs a repetition for mapping a data signal and a demodulation reference signal (DMRS) repeatedly at a symbol level over a plurality of subframes. A signal allocation unit (213) maps, in the a plurality of subframes, the repeated DMRS to symbols other than symbols corresponding to an SRS resource candidate, which is a candidate for a resource to which a sounding reference signal (SRS) to be used to measure an uplink received signal quality is to be mapped. A transmission unit (216) transmits an uplink signal (PUSCH) including the DMRS and the data signal over the a plurality of subframes.
