1. A communication system configured to support a self-contained subframe that includes both of downlink communication and uplink communication and in which the uplink communication includes a response to the downlink communication, comprising:
a user apparatus; and
a base station configured to wirelessly communicate with the user apparatus,
wherein, with respect to the self-contained subframe, the base station configures a gap from the downlink communication to the uplink communication, and configures downlink communication length and uplink communication length in symbols,
the base station transmits, to the user apparatus, a first list for the downlink communication length and a second list for the uplink communication length,
the self-contained subframe includes downlink data, downlink scheduling information including an identifier for selecting the downlink communication length from the first list, and uplink scheduling information including an identifier for selecting the uplink communication length from the second list, and
the base station transmits, to the user apparatus, information indicating a delay time from notification of the downlink scheduling information to reception of the downlink data.
