In a case of configuring multiple configured grants, signal detection in a base station apparatus is efficiently performed. For configured grant scheduling, by configuring a plurality of time offset values, multiple transmission opportunities are generated. To each of the transmission opportunities, a slot retransmission is applied. In a case that multiple transmission patterns are generated due to the plurality of time offsets, transmission is performed by using a transmission pattern, among the multiple transmission patterns, that causes the number of remaining retransmissions to increase.
