Abstract

Some embodiments in the present disclosure relate to facilitating coexistence of communication applications and sensing applications in at least partially overlapping bandwidths. A sensing device, a joint sensing and communication device and/or a communication device are provided that transmit a request for transmission resources to a scheduling device in a communication format compliant with a communication standard. In response, the scheduling device allocates resources corresponding to a frame format compliant with a communication standard according to which the communication device operates, if the request was for a communication application or the scheduling device allocates resources corresponding to a frame format compliant with the communication standard or to a frame format suitable for a sensing application, if the request was for the sensing application. The selection of the frame format for the sensing application may further depend on the priority of the sensing application or further features of the application or environment or channel or the like. The wireless device which receives the allocation schedules the signal transmission accordingly and may provide feedback to the scheduling device for adaptive frame format selection.
