1. A device, comprising:
a radio transceiver comprising at least one antenna array configured to support multiple input multiple output (MIMO) communication for both data communication and a radar probing,
at least one processor configured to communicate, via the radio transceiver, data on a radio channel according to a radio access technology, the radio access technology comprising pilot signals and transmission blocks for the data,
wherein the at least one processor is configured to control the radio transceiver to participate in the radar probing employing at least some of the pilot signals as radar probe pulses of the radar probing, the radar probing being based on one or more receive properties of echoes of the radar probe pulses, and wherein the at least one processor is further configured to employ one or more resource mappings to coordinate resource-usage of transmissions of the data communication and transmissions of the radar probing that are both transmitted from the radio transceiver such that data communication transmissions and radar probing transmissions use different resources while being transmitted from the radio transceiver, and
wherein the at least one antenna array comprises a first antenna configured to transmit the radar probe pulses and a second antenna configured to receive the echoes of the radar probe pulses.
