Method and device for reducing performance difference between contents and devices in communication system

A method performed by a second electronic device configured to render augmented reality (AR) content, the method comprising:

• receiving, from a first electronic device, a first report including measurement time information associated with a time when a pose of a user wearing the first electronic device is measured and measurement pose information associated with the measured pose, the measurement pose information including a location and gazing direction of the user;
• determining, based on the first report, a target point when an AR image is displayed;
• generating, based on the first report, a predicted image for the target point;
• and
• transmitting, to the first electronic device, data of the predicted image and the target point, wherein the first report further includes capability information related to an image processing time of the first electronic device.

A first electronic device configured to display AR content, comprising:

• a transceiver;
• a display;
• and
• a controller connected with the transceiver and the display, the controller configured to:
• obtain measurement time information associated with a time when a pose of a user wearing the first electronic device is measured and measurement pose information associated with the measured pose of the user, the measurement pose information a a location and gazing direction of the user;
• generate a first report including the measurement time information and the measurement pose information;
• transmit the first report to a second electronic device;
• receive, from the second electronic device, data of predicted image and a target point generated by the second electronic device, the predicted image for the target point generated based on the first report;
• and
• display an AR image at the target point based on the predicted image,
• wherein the first report further includes capability information related to an image processing time of the first electronic device.
