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.

Adaptive frame selection for sensing and joint sensing and communication applications

The present disclosure relates to the detection of impairments in a received wireless communication signal. It may detect the presence of each of N types (sources) of impairments and possibly the amount of the impairment present in the received signal. The detection includes processing of the received signal by a trainable model trained to distinguish N sources of impairments by applying learning, with N being an integer larger than one. The trainable model outputs, for each source j of the N sources, a contribution of the j-th source of impairments to the obtained signal. The contribution may be binary, indicating the presence or absence of the j-th source of impairment, or may also indicate the amount of impairment.

Multiple radio frequency impairment estimation

The method of the invention is related to utilizing the convergence patterns of sparse coding for detecting a primary user emulation/signal jamming attack in a cognitive radio setting. The method basically comprises a training stage and a testing stage. Through the method, the hypothesis which shows that there is no primary user but only noise (H), the hypothesis which shows that there is a legitimate primary user present with a right to use the spectrum and the secondary user should not use the spectrum (H), and the hypothesis which shows that there is a primary user emulator/signal jammer in the environment (H) can be distinguished.
