1. A communication apparatus configured for use in a case that a first device that is a NR communication apparatus and a second device that is an LTE communication apparatus coexist, the communication apparatus comprising:
a transceiver that performs radio communication;
a control circuit that controls an operation of sensing time-frequency resources to be used in a communication scheme for inter-device communication with the first and second devices,
wherein the transceiver uses different numerologies which correspond to different time-frequency resources with the first and second devices,
wherein the transceiver uses a first numerology of the different numerologies corresponding to a first time-frequency resource of the different time-frequency resources with the first device, and uses a second numerology of the different numerologies corresponding to a second time-frequency resource of the different time-frequency resources with the second device,
wherein the different numerologies are orthogonal to each other,
wherein the control circuit controls to sense the time-frequency resources on a time axis in units of symbols based on a slot format received by the transceiver, and
wherein the control circuit controls to notify of information regarding any time-frequency resource of the time-frequency resources that has been reserved, via the transceiver,
wherein the first time-frequency resource is selected from within a predetermined sensing window based on a result of a power measurement sensing performed in the predetermined sensing window in a minimum unit of a transmission resource block in a frequency axis, and
wherein the second time-frequency resource of the different numerologies is selected from within a resource selection window based on a time-frequency resource reservation status, the resource selection window following the predetermined sensing window.
