Abstract

A base station apparatus determines which mode of a subframe bundling mode (second mode) and a non-bundling mode (first mode) should be used by a user apparatus for communication, and reports a determination result. In the first mode, RTT period is a first period, and each of transmission and retransmission of the signal is performed every 1 TTI. In the second mode, RTT period is a second period that is longer than the first period, and each of transmission and retransmission of the signal is performed every plurality of TTIs. A radio resource to be used for retransmission is determined according to a first frequency hopping pattern in the first mode, and is determined according to a second frequency hopping pattern that is different from the first frequency hopping pattern in the second mode.
