1. A first terminal device, comprising:
circuitry configured to:
execute a first carrier sense to acquire access rights for a first plurality of radio resources;
transmit first resource information, which indicates a first radio resource available to a first communication device among the first plurality of radio resources, on an uplink or a sidelink;
receive, from a second terminal device different from the first terminal device, second resource information which indicates a radio resource of a second plurality of radio resources is available to a second communication device other than the second terminal device, wherein the second terminal device executes a second carrier sense to acquire access rights for the second plurality of radio resources; and
transmit a signal with a transmission power equal to or less than a transmission power assumed in the second carrier sense, by using the radio resource available to the second communication device.
