Abstract: An encoder that encodes a current block to be encoded in an image is provided. The encoder includes: processor; and memory coupled to the processor, in which, in operation, the processor: generates a first prediction image based on a motion vector, the first prediction image being an image with full-pel precision; generates a second prediction image using an interpolation filter by interpolating a value at a fractional-pel position between full-pel positions included in the first prediction image; and encodes the current block based on the second prediction image, and in the using of the interpolation filter, the interpolation filter is switched between a first interpolation filter and a second interpolation filter differing in a total number of taps from the first interpolation filter.

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: The present disclosure relates to a user equipment comprising a receiver receiving a minimum-system-information message from a first radio base station. System information for the first radio cell that can be acquired by the UE is carried within the minimum-SI message and one or more additional-SI messages. The minimum-SI message includes system information for accessing the first radio cell and at least one system information index, each of which is associated with one of the additional-SI messages. The SI message index comprises a value tag and an area pointer, the latter pointing to one area already defined. Processing circuitry determines whether the UE had already acquired before the additional-SI message associated with the same value tag and the same area. If the determination is positive, the processing circuitry determines that system information included in said additional-SI message acquired before is applicable to the first radio cell.

Abstract: A reception apparatus according to the present disclosure includes a receiver which, in operation, receives a downlink signal including a first data signal for the reception apparatus and first Reference Signals for Phase Tracking (PT-RS). The first data signal is mapped on a first set of subcarriers and the first PT-RS is mapped to the downlink signal based on a first Modulation and Coding Scheme (MCS) configured for the first data signal. The reception apparatus according also includes a circuit which, in operation, estimates a phase noise using the first PT-RS included in the downlink signal.

Abstract: Provided are wireless communication methods, a UE and an eNB. The wireless communication method performed by a UE includes transmitting transport block repetitions to an eNB, wherein one HARQ process includes multiple repetition sets of a transport block if one repetition set of the transport block is not enough for the eNB to successfully decode the transport block, each of the multiple repetition sets includes multiple repetitions of the transport block, each of the multiple repetition sets is followed by a feedback channel to indicate whether the transport block is successfully decoded by the eNB.

Abstract: A terminal with which it is possible to appropriately transmit uplink control information. In a terminal (200), a reception unit (202) receives first control information relating to an uplink data channel, and a second control information relating to an uplink control channel for transmitting uplink control information. The first control information includes first indication information indicating the presence or absence of an uplink data transmission and second indication information indicating the presence or absence a channel state information transmission. A transmission unit (220) transmits uplink control information using the resource of the uplink data channel when the first indication information indicates that there is no uplink data transmission and the second indication information indicates that there is no channel state information transmission.

Abstract: An encoder includes circuitry and a memory coupled to the circuitry, wherein the circuitry, in operation, performs a partition process. The partition process includes calculating first values of a set of pixels between a first partition and a second partition in a current block, using a first motion vector for the first partition; calculating second values of the set of pixels, using a second motion vector for the second partition; and calculating third values of the set of pixels by weighting the first values and the second values. When a ratio of a width to a height of the current block is larger than 4 or a ratio of the height to the width of the current block is larger than 4, the circuitry disables the partition process.
