Abstract: A terminal is disclosed, which is capable of appropriately distributing transmission power when transmission time interval (TTI) lengths are different. A transmission-power determining section (211) determines transmission power for an uplink signal in a first TTI and an uplink signal in a second TTI shorter in TTI length than the first TTI, when the second TTI uplink signal occurs during a first interval in the first TTI, so as to keep the transmission power for the first reference signal and the first TTI uplink signal constant without allocating any transmission power to the second TTI uplink signal in the first interval, and to reduce the transmission power for the first TTI uplink signal to allocate transmission power to the second TTI uplink signal in a second interval which is subsequent to the first interval in the first TTI.

Abstract: The present disclosure relates to receiving and transmitting data in a frame with subframes of a wireless communication system, each subframe being either an uplink subframe accommodating uplink signal, a downlink subframe accommodating downlink signal or a special subframe including a downlink signal portion as well as an uplink signal portion. A control signal includes a special subframe configuration specifying the length of the uplink and/or downlink portion of the special subframe. The mapping and demapping of user data and/or control data including feedback information in a transmission time interval, TTI, onto or from one subframe is then performed, wherein the length of a second TTI for mapping onto the uplink portion of a special subframe is shorter than a first TTI for mapping onto an uplink subframe, or a first number of TTIs mapped onto the uplink subframe is larger than a second number of TTIs for mapping onto the uplink portion of a special subframe. The data are received or transmitted accordingly.

Abstract: In a terminal (200), a HARQ-ACK generator (208) generates one or more response signals for respective code block groups based on a parameter included in each of a plurality of downlink control signals, the code block groups forming each of a plurality of transport blocks to be assigned by the plurality of downlink control signals, the parameter relating to the number of code block groups. A transmitter (211) collectively transmits the response signals for the respective code block groups. A value of the parameter herein is to be configured, at least using a first granularity coarser than a second granularity in units of the code block groups.

Abstract: A parameter required for an operation in a flexible bandwidth is appropriately determined. A base station (100) is disclosed in which: a controller (101) determines a parameter for a band composed of a first band and a segment that is an additional band for the first band, the band composed of the first band and the segment being referred to as a second band; and a transmitter (113) communicates with a terminal in the second band, using the parameter.

Abstract: The disclosure relates to a transmitting device for transmitting periodic data via a sidelink interface to one or more receiving devices. The transmitting device autonomously selects radio resources for transmitting periodic and aperiodic data via the sidelink interface. A transmitter transmits first periodic data together with first scheduling information to the one or more receiving devices. The first scheduling information indicates radio resources used for transmitting the first periodic data and further indicates reserved radio resources usable at a later point in time by the transmitting device to transmit second periodic data. A processor delays the second periodic data until the later point in time. The transmitter transmits the second periodic data at the later point in time using the reserved radio resources indicated by the first scheduling information. On the other hand, the transmitter transmits other data than the first periodic data at the earliest possible point in time upon becoming available for transmission.

Abstract: A communication apparatus includes circuitry that determines a number of resource blocks forming a resource block group, which is a unit used to allocate a resource to the communication apparatus, in a first band or in a second band that is an expanded band to which the first band is expanded, and a subcarrier spacing for the second band is same or different from a subcarrier spacing for the first band; and a transceiver that is coupled to the circuitry and that communicates with a base station using the resource. One of the number of resource blocks set for the first band and the number of resource blocks set for the second band is an integer multiple of the other, and the number of resource blocks set for the first band and the number of resource blocks set for the second band are values that are a power of two.

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: Provided are a user equipment and a wireless communication method for LAA. The user equipment comprises: a receiver operative to receive a UL grant which schedules a subframe for UL transmission; a first circuit operative to perform LBT; a transmitter operative to transmit a PUSCH in the scheduled subframe starting from one available starting position of multiple candidate starting positions in the scheduled subframe if the LBT is successful. According to present disclosure, it is possible to increase the possibility that PUSCH could be sent in the scheduled subframe after LBT.
