Claim 4:
5. A method performed by an electronic device configured to operate as a first user equipment in a New Radio (NR) wireless communication system, the method comprising:
acquiring a default preconfiguration for sidelink communication from a base station to be used by the first user equipment when the first user equipment is not in range of the base station,
wherein the default preconfiguration for sidelink communication comprises:
one or more subcarrier spacings for sidelink communication, and
one or more cyclic prefix types for sidelink communication;

acquiring a user equipment capability of a second user equipment for sidelink communication,
wherein the user equipment capability of the second user equipment comprises:
a cyclic prefix type of the one or more cyclic prefix types, and
an integer corresponding to a subcarrier spacing of the one or more subcarrier spacings;

after acquiring the user equipment capability of the second user equipment, determining whether or not the first user equipment is in range of the base station;
only upon determining the first user equipment is not in range of the base station determining, based on the acquired user equipment capability of the second user equipment, a subcarrier spacing from one or more subcarrier spacings in the default preconfiguration for sidelink communication; and
performing sidelink communication with the second user equipment based on the subcarrier spacing,
wherein, based on the acquired user equipment capability of the second user equipment, the sidelink communication is performed in accordance with a default preconfiguration specific number of slots in a subframe, a default preconfiguration specific number of Orthogonal Frequency Division Multiplexed (OFDM) symbols in a slot, and a default preconfiguration specific number of slots in a frame.
