    Abstract: The invention relates to a radio base station or user equipment for scheduling respectively performing uplink transmissions via an unlicensed cell configured between the user equipment and the radio base station. The UE can perform an uplink transmission via the unlicensed cell according to at least the following types. A first type spans a complete subframe duration and starts and ends at subframe boundaries followed by the UE. A second type spans a complete subframe duration and includes an additional time offset with respect to the subframe boundaries followed by the UE. A third type spans less than a complete subframe duration and includes an additional time offset with respect to the subframe boundaries followed by the UE. The UEs perform uplink transmissions according to one of the types in such a manner that at least between two directly-subsequent uplink transmissions a time gap with no uplink transmission occurs.

    Abstract: An encoder includes memory and circuitry. Using the memory, the circuitry: in a first operating mode, derives a first motion vector in a unit of a prediction block obtained by splitting an image included in a video, and performs, in the unit of the prediction block, a first motion compensation process that generates a prediction image by referring to a spatial gradient of luminance in an image generated by performing motion compensation using the first motion vector derived; and in a second operating mode, derives a second motion vector in a unit of a sub-block obtained by splitting the prediction block, and performs, in the unit of the sub-block, a second motion compensation process that generates a prediction image without referring to a spatial gradient of luminance in an image generated by performing motion compensation using the second motion vector derived.

    Abstract: A hub is connected to first and second networks where first-type and second-type frames are transmitted following first and second communication protocols. The hub sequentially receives each of the first-type and second-type frames, and stores data in first and second reception buffers. If the destination of data stored in the first and second reception buffers is the first network, the hub stores the data in a first transmission buffer. If the destination is the second network, the hub stores the data in a second transmission buffer. If the first transmission buffer is a priority transmission buffer, the hub transmits first yet-to-be-transmitted data in the first transmission buffer with priority. If the second transmission buffer is the priority transmission buffer, the hub transmits second yet-to-be-transmitted data in the second transmission buffer with priority.

    Abstract: An encoding method changes an encoding rate of an erasure correcting code. One cycle is defined as 12k bits (wherein k represents a natural number) which is an encoding output using LDPC-CC with an encoding rate of 1/2, and includes information and parity. From the one cycle, only the information is arranged in the output order of the encoding output to obtain 6k bit information X6i, X6i+1, X6i+2, X6i+3, X6i+4, X6i+5, . . . , X6(i+k−1) X6(i+k−1)+1, X6(i+k−1)+2, X6(i+k−1)+3, X6(i+k−1)+4, and X6(i+k−1)+5. Known information is inserted in 3k pieces of information (Xj) among the 6k bit information, so that when 3k pieces of mutually different j is divided by 3, there is a remainder of 0 regarding k pieces, there is a remainder of 1 regarding k pieces, and there is a remainder of 2 regarding k pieces, to thereby obtain the parity from the information containing the known information.
