Abstract: A communication apparatus includes a circuitry and a transmitter. In operation, the circuitry generates a Demodulation Reference Signal (DMRS) and generates downlink control information indicating a mapping pattern of the DMRS from a plurality of mapping patterns, and the transmitter transmits the DMRS and the downlink control information. The plurality of mapping patterns include a first mapping pattern and a second mapping pattern. Resource elements used for the DMRS of the second mapping pattern are same as a part of resource elements used for the DMRS of the first mapping pattern. A number of the resource elements used for the DMRS of the first mapping pattern is larger than a number of the resource elements used for the DMRS of the second mapping pattern.

Abstract: A decoding method includes: determining a numerical range based on whether intra prediction or inter prediction is to be used to decode encoded first information of a current three-dimensional point; and switching a context between a first context and a second context to entropy-decode the encoded first information, based on whether an absolute value of decoded second information of the current three-dimensional point is included in the numerical range determined.

Abstract: The communication apparatus comprises a receiver which, in operation, receives a PHY layer Data Unit that includes a duration field; Physical (PHY) layer circuitry which, in operation, issues a PHY-CCA (clear channel assessment) primitive parameter indicating bandwidth information on a busy or idle state for each subchannel within an operating bandwidth; and Media Access Control (MAC) circuitry which, in operation, updates a Network Allocation Vector (NAV) value based on the duration information and, in operation, determines busy/idle state of at least one subchannel, wherein the MAC circuitry, in operation, controls transmission of the HE TB PHY layer Data Unit based on the updated NAV value and the busy/idle state of the at least one subchannel, and controls the PHY circuitry to have the HE TB PHY layer Data Unit transmitted when the at least one subchannel is considered idle, regardless of whether the primary subchannel is busy or not.

Abstract: A decoder that decodes a current block using a motion vector includes: a processor; and memory. Using the memory, the processor: derives a first candidate vector from one or more candidate vectors of one or more neighboring blocks that neighbor the current block; determines, in a first reference picture for the current block, a first adjacent region that includes a position indicated by the first candidate vector; calculates evaluation values of a plurality of candidate regions included in the first adjacent region; and determines a first motion vector of the current block, based on a first candidate region having a smallest evaluation value among the evaluation values. The first adjacent region is included in a first motion estimation region determined based on the position indicated by the first candidate vector.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry encodes second information indicating whether first information is present in a bitstream, the first information being regarding a subpicture which is a rectangular region in a picture, the picture including slices, and when the second information indicates that the first information is present in the bitstream, each of the slices is a rectangular slice and has a subpicture index indicating a subpicture to which the slice belongs.

Abstract: An invention relates to methods for transmitting a buffer status report (BSR) in a mobile communication system, more particularly to the definition of rules for triggering, generating and transmitting BSRs. The invention also relates to a data transmission method utilizing new rules to decide data of which radio bearers is transmitted within a given transmission time interval. Moreover, the invention relates to scheduling method for radio resources that is taking into account additional scheduling-relevant information from the buffer status reporting and/or data transmission method. To avoid unnecessary grants from the network and to suggest an advanced handling of data transmissions the invention suggests a buffer status reporting and data transmission schemes that take into account the scheduling mode of data of radio bearers pending for transmission to decide whether to report on it in a buffer status report, respectively, whether to multiplex the data to a transport block for transmission.
