Abstract: In the present invention, regarding a narrowband used in a subframe for transmitting uplink data, if a switch is made from a first narrowband used in a first subframe to a second narrowband that is different from the first narrowband, with respect to a second subframe continuing to the first subframe, a final one symbol of the first subframe and an initial one symbol of the second subframe are punctured and set as a retuning time to transmit the uplink data in the first narrowband and the second narrowband.

Abstract: UEs each monitor a search space in multiple CORSETs and appropriately detect a DCI. In a base station (100), a DCI generator (102) selects one of multiple cases each indicating a combination of CORSETs to be monitored by a terminal (200) among multiple control channel regions (CORSETs). A transmitter (106) indicates, by higher-layer signaling, configuration information indicating the multiple cases, and indicates the selected case by dynamic signaling.

Abstract: The present disclosure relates to a data transmitting device, data receiving device and the corresponding data transmitting method and data receiving method for transmitting/receiving data over a wireless channel in a communication system. In particular, a first resource grant is received for a data transmission in a subframe and a second resource grant for a data transmission of data in said subframe. Then, it is determined, according to which of the first resource grant and the second resource grant data are to be transmitted in the subframe; and the data is transmitted in the subframe according to the selected first grant or second grant.

Abstract: A base station capable of appropriately transmitting a reference signal in an unlicensed band and a reception quality report measured using said reference signal. A control unit (102) of a base station (100) changes: the reference signal transmission timing which was set before carrier sensing on the basis of a time resource set according to carrier sensing results; and/or the report timing of the quality information measured in a terminal 200 using the reference signal. A transmission unit (108) and a receiving unit (109) communicate the reference signal or quality information on the basis of the changed timing.

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 includes 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: In a terminal, an SRS drop control unit drops a portion of partial bands from among a plurality of partial bands in a case where transmission power for reference signals generated using a plurality of sequences having a sequence length that corresponds to a partial band exceeds a threshold value. Furthermore, a radio transmission unit transmits the reference signals by means of the remaining partial bands other than the portion of partial bands that are dropped from among the plurality of partial bands.

Abstract: In a base station, a controller, when communicating with a terminal using a time unit including a downlink time resource for a downlink control signal, a downlink time resource assigned for downlink data by the downlink control signal, and a uplink time resource for a response signal for the downlink data, sets the amount of the uplink time resource used by the terminal for transmission of the response signal to be larger as the time unit is longer.
