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: An encoder includes memory and circuitry coupled to the memory. The circuitry is configured to: generate an encoded bitstream that includes a multi-layer structure; and store, in the encoded bitstream, a syntax element having a value indicating that a layer in the multi-layer structure to be output by a decoder is arbitrarily specified, the syntax element defining that at least one layer is to be output from among layers arbitrarily specifiable by the decoder.

Abstract: A frame transmission prevention apparatus connected to a network of a network system including a plurality of electronic control units communicating with one another via the network is provided. The apparatus includes a processor and a memory. The memory includes at least one set of instructions that causes the processor to perform processes when executed by the processor. The processes include receiving a first frame from the network and switching whether to perform a first process for preventing transmission of the first frame on the basis of management information indicating whether prevention of transmission of a frame is permitted if the first frame satisfies a first condition.

Abstract: A base station that suitably controls retransmission in license-free bands. In the base station (100), a transmission unit (107) sends control information pertaining to retransmission requests for response signals for downlink data and a reception unit (108) receives response signals that have been retransmitted on the basis of the control information. The control information identifies one among a plurality of candidate values pertaining to the number of response signals requested for retransmission. The plurality of candidate values are set on the basis of any one of a plurality of grain sizes.

Abstract: Provided are a resource scheduling method, a resource determining method, an eNB, and a user equipment. The resource scheduling method for wireless communication is performed by the eNB. The wireless communication involves at least a first carrier and a second carrier. The resource scheduling method includes: transmitting a DCI in the first carrier to a UE to schedule downlink resources for a PDSCH of the second carrier, wherein the eNB is able to start transmitting a burst in the second carrier at a flexible time independent of the subframe boundaries of the second carrier after the second carrier is occupied by the eNB, and the DCI for a flexible PDSCH of the burst different from the normal PDSCH of the second carrier contains information on the time period scheduled for the flexible PDSCH. The flexible PDSCH and its corresponding RS can reuse the DwPTS subframe structure for minimal specification impact.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry encodes a hypothetical reference decoder (HRD) parameter into a buffering period supplemental enhancement information (SEI) message independently from a sequence parameter set. The HRD parameter is related to a decoding unit and an HRD.

Abstract: In a base station, control circuitry determines, based on an offset for defining a frequency position of a narrowband allocated to an MPDCCH and a resource block group size of a system band, allocations of a first EPDCCH set and a second EPDCCH set that constitute the MPDCCH. The MPDCCH is a PDCCH for MTC. The second EPDCCH set has a different number of PRBs from the first EPDCCH set. A transmitter transmits a control signal according to the allocations of the first EPDCCH set and the second EPDCCH set. Further, the control circuitry controls a number of RBGs in which both the first EPDCCH set and the second EPDCCH set are allocated to be zero or one.

Abstract: To provide a bandwidth extension method which allows reduction of computation amount in bandwidth extension and suppression of deterioration of quality in the bandwidth to be extended. In the bandwidth extension method: a low frequency bandwidth signal is transformed into a QMF domain to generate a first low frequency QMF spectrum; pitch-shifted signals are generated by applying different shifting factors on the low frequency bandwidth signal; a high frequency QMF spectrum is generated by time-stretching the pitch-shifted signals in the QMF domain; the high frequency QMF spectrum is modified; and the modified high frequency QMF spectrum is combined with the first low frequency QMF spectrum.
