Abstract: A base station (100, 300) is provided with a transmitter and a receiver. The transmitter (109) transmits a downlink signal in a downlink transmission region, in a time unit that includes the downlink transmission region, an uplink transmission region, and a gap period that is a switching point between the downlink transmission region and the uplink transmission region. The receiver (111) receives an uplink signal in the uplink transmission region, in the time unit. Furthermore, a delay tolerant signal for which a delay is tolerated more than for the downlink signal and the uplink signal is mapped to within the gap period.

Abstract: A resource assignment determiner determines a resource for a PDSCH intended for an MTC terminal, and a transmitter transmits an MPDCCH that includes resource assignment bits indicating the resource thus determined and transmits the PDSCH using the resource thus determined. The MPDCCH is a PDCCH intended for the MTC terminal. The resource assignment bits are associated with a resource that is used when the MPDCCH and the PDSCH are transmitted in the same subframe and a resource that is used when the MPDCCH and the PDSCH are transmitted in different subframes.

Abstract: In a terminal, in a slot having allocated thereto both an uplink control channel (PUCCH) and an uplink channel (PUSCH) that includes uplink data, in a case where the difference between the power spectrum density (PSD) of the PUCCH and the PSD of the PUSCH is greater than a threshold value (permitted difference), a control unit drops symbols of the PUSCH in a transmission interval for the PUSCH overlapping with a transmission interval for the PUCCH. A transmission unit transmits at least the PUCCH in the slot.

Abstract: The present disclosure provides a method of setting reserved subframes for indication of a resource pool by a bitmap, a user equipment, and a base station. In the present disclosure, the resource pool is used for transmitting or receiving sidelink signals within a system frame number cycle that includes predefined subframes and remaining subframes that are subframes after excluding the predefined subframes within the system frame number cycle. In the method, a number of the reserved subframes is determined so that the bitmap is repeated by integer times within the subframes after excluding the reserved subframes and the predefined subframes within the system frame number cycle. In the method, position of each of the reserved subframes is set, wherein at most two reserved subframes are set per n subframes within the system frame number cycle.
