Claim of US Patent No. 10,993,276

1. A radio communication device comprising:circuitry configured to
determine connection processing, for connecting the radio communication device to another radio communication device, activated in accordance with a first input operation by a user of the radio communication device,
receive information including a connection state between the radio communication device and the other radio communication device, and a communication capability of the other radio communication device to which the radio communication device attempts to connect, and
select, depending on the connection state and the communication capability, which communication is to be performed from among
first connection mode in which a direct connection to the other radio communication device is established and direct communication with the other radio communication device is performed, wherein the first connection mode is performed by disconnecting the connection between the other radio communication device and a base station or performed without disconnecting such connection,
second connection mode in which a connection to the other radio communication device via the base station that relays radio communication is established and direct communication with the other radio communication device is performed, and
third connection mode in which a connection to the other radio communication device via the base station is established and indirect communication with the other radio communication device via the base station is performed.
