Provided are an edge data network for streaming a virtual reality (VR) image and a device for displaying a VR image. An example method, performed by the edge data network, of streaming a VR image includes receiving gaze information of a user viewing the VR image from a device, determining at least a partial region among all of regions of the VR image as an artificial intelligence (AI) scaling target region of the VR image, based on the gaze information, determining an AI scaling change level for the AI scaling target region, performing a scaling change on a region corresponding to the AI scaling target region among the regions of the VR image obtained from a media server, according to the AI scaling change level, generating VR image data including the AI scaling target region, and streaming the VR image data to the device.

Method and apparatus for streaming VR image

A cognitive radio communication apparatus and method to control a sensing operation. The cognitive radio communication apparatus includes an information receiver to receive channel state information associated with a channel occupancy state of a primary system from at least one sensing node of a secondary system; a sensing control unit to control a sensing period of the at least one sensing node according to a change pattern of the channel occupancy state, based on the channel state information; and a control information transmitter to transmit control information associated with the controlled sensing period to at least one member node of the secondary system.
