The control section 301 controls the scheduling (for example, resource allocation) of system information, downlink data signals (for example, signals transmitted in the PDSCH), downlink control signals (for example, signals transmitted in the PDCCH and/or the EPDCCH, such as delivery acknowledgment information), and so on. Also, the control section 301 controls the generation of downlink control signals, downlink data signals and so on, based on the results of deciding whether or not retransmission control is necessary for uplink data signals, and so on. Also, the control section 301 controls the scheduling of synchronization signals (for example, the PSS (Primary Synchronization Signal)/SSS (Secondary Synchronization Signal)), downlink reference signals (for example, the CRS, the CSI-RS, the DMRS, etc.) and so on.
In addition, the control section 301 may control the scheduling of uplink data signals (for example, signals transmitted in the PUSCH), uplink control signals (for example, signals transmitted in the PUCCH and/or the PUSCH, such as acknowledgment information), random access preambles (for example, signal transmitted by the PRACH), uplink reference signals and so on.
The control section 301 controls the transmission and/or receipt of signals based on a first TTI (for example, a long TTI an nTTI, a slot, etc.) and a second TTI (for example, a short TTI, an sTTI, a minislot, etc.), which has a shorter TTI duration than the first TTI. The control section 301 may control information as to which of the first TTI and the second TTI is used to be transmitted to the user terminal 20.
