Abstract: A communication apparatus includes circuitry and a transmitter. The circuitry sets a number of physical downlink control channel (PDCCH) candidates per aggregation level in a search space of a signal, and indicates the set number of PDCCH candidates to a user equipment (UE) wherein the search space is monitored by the UE based on the set number of PDCCH candidates. The transmitter transmit the signal. A maximum number of monitored PDCCH candidates per slot depends on a subcarrier interval. A first subcarrier interval is one-quarter as wide as a second subcarrier interval, and a first maximum number of monitored PDCCH candidates per slot with the first subcarrier interval is not four times as high as a second maximum number of monitored PDCCH candidates per slot with the second subcarrier interval.

Abstract: A repetition unit (212) performs a repetition for mapping a data signal and a demodulation reference signal (DMRS) repeatedly at a symbol level over a plurality of subframes. A signal allocation unit (213) maps, in the a plurality of subframes, the repeated DMRS to symbols other than symbols corresponding to an SRS resource candidate, which is a candidate for a resource to which a sounding reference signal (SRS) to be used to measure an uplink received signal quality is to be mapped. A transmission unit (216) transmits an uplink signal (PUSCH) including the DMRS and the data signal over the a plurality of subframes.

Abstract: There are provided an apparatus, a method and a system. The apparatus comprises: a transmitter operative to transmit wireless data or signals to a second node; and a circuitry operative to determine whether one or more reserved periods are reserved between two continuous data or signals transmitted by the transmitter based on a length of configured transmission time intervals (TTIs), wherein the circuitry is further operative to: determine the one or more reserved periods are reserved between two continuous data or signals in a case that the length of configured TTI is shorter than or equal to a threshold.

Abstract: A base station includes: an allocating circuit that allocates, to a resource set which is monitored by a terminal belonging to a group, a first control signal which contains information indicating the configuration of a slot and a second control signal which does not contain the information indicating the configuration of a slot; and a transmitter that transmits the first control signal and the second control signal to a terminal. The number of symbols to which the first control signal is allocated is made equal to the smallest number of symbols to which the second control signal is allocated.

Abstract: A repeater generates repetition signals by repeating an uplink signal over a plurality of subframes. If the plurality of subframes do not include a transmission candidate subframe of a sounding reference signal used to measure uplink reception quality, a controller sets a first transmission format to all the plurality of subframes, and if the plurality of subframes include the transmission candidate subframe, the controller sets a second transmission format to all the plurality of subframes. A transmitter transmits the repetition signals using the set transmission format.

Abstract: In a terminal that judges whether to trigger a handover from a serving cell to another cell, a RSRQ/RSRP measurer measures a first received quality value by using a cell-specific reference signal transmitted from the neighboring cell or a second received quality value by using a cell-detection reference signal transmitted from the neighboring cell. An offset adder calculates a third received quality value by adding an offset value to the second received quality value. A judging circuitry judges whether the first received quality value or the third received quality value satisfies a handover triggering condition with reference to the cell-specific reference signal. A transmitter transmits trigger information to the neighboring cell in order to activate handover from a serving cell to the neighboring cell, based on the judgement results.
