1. A communication apparatus comprising:
a transceiver that performs radio communication;
a control circuitry that:
selects a first and second time-frequency resource, in units of symbols based on a slot format that has been received by the transceiver, to be used in a communication scheme for inter-device communication with a first and second device, respectively, and
performs the inter-device communication with the first and second devices via the selected first and second time-frequency resources,
wherein the first and second time-frequency resources are selected from a plurality of time-frequency resources of a numerology, the numerology being one of a plurality of different numerologies that are set orthogonally, each of the plurality of different numerologies corresponding to different sets of time-frequency resources,
wherein the first time-frequency resource is selected from within a sensing window based on a result of a power measurement sensing performed in the sensing window in a minimum unit of a transmission resource block in a frequency axis, and
wherein the second time-frequency resource is selected from within a resource selection window based on a time-frequency resource reservation status. the resource selection window following the sensing window.
