ABSTRACT:
In digital communications that utilize a data packet format wherein each data packet includes a physical layer (PHY) component and a media access control layer (MAC) component, the media access control layer component can be selectively protected by forward error correction (FEC). The receiving end receives an indication as to whether FEC has been applied, and makes an FEC decision based (12-15) on this indication. The accuracy of the received-side FEC decision and the robustness of the FEC indication can be improved by: making the FEC decision based on the results of FEC decoding applied to a media access control layer header within the media access control layer component; providing an FEC indication bit in the physical layer component; and using a plurality of bits to encode the FEC indication in either the physical layer component or the media access control layer component.
