Abstract
A terminal device including a control unit that transmits first resource information, which indicates a radio resource available to another communication device among radio resources of which access rights are acquired by performing carrier sense, on an uplink or a sidelink.
Claims18
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.

A base station device, comprising:
- circuitry configured to:
- receive, from a first terminal device, first resource information which indicates a radio resource of a first plurality of radio resources is available to a first communication device other than the first terminal device, wherein the first terminal device executes a first carrier sense to acquire access rights for the first plurality of radio resources;
- execute a communication based on and use the radio resource available to the first communication device;
- 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.
3 more elements
A method performed by a processor of a first terminal device, comprising:
- executing a first carrier sense to acquire access rights for a first plurality of radio resources;
- transmitting first resource information, which indicates a radio resource available to a first communication device among the first plurality of radio resources, on an uplink or a sidelink;
- receiving, 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
- transmitting 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.
