1. A terminal device comprising:a transceiver configured to perform wireless communication; and
a controller configured to perform control such that control information regarding a supported communication scheme is transmitted to an external device through the wireless communication,
wherein, in a case in which a first communication scheme and a second communication scheme different from the first communication scheme are supported, the controller associates, with the control information, a set of parameters that include:
a terminal device capability indicating at least one of an uplink capability, a downlink capability or a sidelink capability;
a first parameter indicating whether or not dual connectivity based on the first communication scheme and the second communication scheme is supported;
a second parameter indicating whether or not standalone communication based on the first communication scheme is supported; and
a supported parameter set indicator that indicates which parameter set of plural parameter sets of the first communication scheme is supported by the terminal device,
wherein the indicated parameter set includes information related to at least one of a sub carrier interval, a number of sub carriers per resource block in a cell, a number of symbols per sub frame, or a cyclic prefix (CP) length type.
