要約
(EN)

In a mobile communication system in which communications is performed by using a downlink frame configuration including a control domain for transmitting downlink control information and a data domain for transmitting downlink user data, each of base stations that performs CoMP communications with a user terminal comprises a transmission unit that transmits the downlink control information by using the data domain in place of the control domain, when the CoMP communication with the user terminal is performed.
