1. A communication apparatus capable of communicating with a master base station and a secondary base station, comprising:
one or more processors; and
one or more memories including instructions that, when executed by the one or more processors, cause the communication apparatus to:
perform connection processing in relation to each of the master base station and the secondary base station,
after a radio resource control (RRC) state of the communication apparatus transits to Inactive state where the communication apparatus is disconnected in a physical layer and is connected in a logical layer, cause the RRC state to transit from the Inactive state to Connected state, where the communication apparatus is connected in the physical layer and the logical layer, and perform the connection processing, and
in a case where connection with the master base station fails as a result of the connection processing, cause the RRC state to transit to Idle state, where the communication apparatus is connected in neither the physical layer nor the logical layer.
