Abstract: The invention relates to a user equipment for being scheduled with uplink radio resources. The user equipment receives from a radio base station a first-stage uplink resource scheduling message, indicating uplink radio resources usable by the UE to perform an uplink transmission via an unlicensed cell. The receiver further receives a second-stage uplink resource scheduling message, which is related to the first-stage uplink resource scheduling message. Upon reception of the second-stage uplink resource scheduling message, a processor of the UE determines that an uplink transmission is scheduled in case the first-stage uplink resource scheduling message is valid. The first-stage uplink resource scheduling message is determined valid based on a determination as to whether an uplink transmission has been triggered by another second-stage uplink resource scheduling message within a predetermined time period prior to reception of the second-stage uplink resource scheduling message. The UE then performs an uplink transmission.

Abstract: Appropriate timing control is realized in accordance with propagation delay between a terminal and a base station. This terminal includes: a control unit that controls a transmission timing on the basis of first information relating to control of transmission timing of signals in a transmission increment of the signals, and second information relating to control of transmission timing in a finer increment than in the transmission increment; and a wireless transmission unit that performs signal transmission on the basis of control of the transmission timing by the control unit.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry, in operation, determines whether a first block is available and whether a second block is available, the first block and the second block being defined relative to a current block to be processed; selects a context model based on whether the first block is available, whether the second block is available, which of inter prediction and intra prediction is to be applied to the first block, and which of inter prediction and intra prediction is to be applied to the second block; and encodes, using the context model selected, a parameter indicating which of intra prediction and inter prediction is to be applied to the current block.

Abstract: Provided is a transmitting device which can expand a communication range when performing multicast/broadcast communication. The transmitting device includes a plurality of transmission antennas, and includes: a signal processor which generates a first baseband signal by modulating data of a first stream, and a second baseband signal by modulating data of a second stream; and a transmitter which generates, from the first baseband signal, first transmission signals having different directivities, generates, from the second baseband signal, second transmission signals having different directivities, and transmits the first transmission signals and the second transmission signals at a same time. When the transmitter has received, from a terminal, a request to transmit the first stream, the transmitter further generates, from the first baseband signal, third transmission signals which are different from the first transmission signals and have different directivities, and transmits the third transmission signals.

Abstract: The present disclosure relates to a user equipment (UE) that comprises a processor, which determines one among a plurality of mobility states for the UE, wherein the plurality of mobility states comprises at least three different mobility states. The processor determines one or more radio measurement quantities of a serving radio cell in which the UE is located. The processor determines whether or not to relax radio measurements on one or more neighbour radio cells, based on the determined mobility state of the UE and the determined one or more radio measurement quantities of the serving radio cell. A receiver and the processor of the UE perform the radio measurements on the one or more neighbour radio cells according to radio measurement requirements, when the processor determines not to relax the radio measurements on the one or more neighbour radio cells.

Abstract: A base station is disclosed, which is capable of appropriately configuring the timings of data assignment, data transmission and reception, and feedback for a case where the DL and UL sTTI lengths are different from each other. In this base station (100), a transmission section (106) transmits a downlink signal using a first short transmission time interval (sTTI) shortened in length than a TTI and used for downlink; and a reception section (107) receives an uplink signal using a second sTTI shortened in length than the TTI and used for uplink. When the first sTTI is shorter in length than the second sTTI, the reception section (107) receives the uplink signal in the second sTTI positioned after a predetermined interval from the transmission timing of the downlink signal, the predetermined interval being configured based on the length of the first sTTI.
