1. A transmitting apparatus, comprising:
a processor configured to configure an orthogonal frequency-division multiple access (OFDMA) frame including resources, each of the resources being defined by time and frequency; and
a transmitter configured to transmit the OFDMA frame over radio waves,
wherein the OFDMA frame includes a resource for communication and resources for sensing, the resource for communication being a time-frequency resource in which a symbol including communication data is transmitted, and each of the resources for sensing being a time-frequency resource in which a symbol for sensing via radio waves is transmitted,
wherein the resources for sensing include a first resource and a second resource, the first resource and the second resource being allocated at different times and having a same frequency, the first resource and the second resource being separated in time axis by a guard interval, and
wherein the resource for communication is at least allocated at a same time and having a different frequency than at least one of the first resource or the second resource.
