Abstract
The disclosed invention presents new approach for FEC implementation as part of existing link between the PHY layer (L1) and MAC layer. In one embodiment a method for providing cellular network Forward Error Correction (FEC) offload, includes merging FEC functionality into the PHY-MAC interface including placing FEC functionality IPs inside a small form factor (SFP) transceiver and allowing configurations from the PHY controller; identifying data carrying packets; encoding/decoding of the data payload; and forwarding an encoded/decoded payload to the next layer.
Claims20
A cellular base station for providing cellular network Forward Error Correction (FEC) offload, comprising:
- a FEC functionality within an interface between a physical layer (PHY) and a media access control layer (MAC), the interface having a first side physically connected to the PHY and having a second side physically connected to the MAC, the FEC functionality further configured to perform steps including:
- identifying data carrying packets;
- forward error correction encoding of the data payload at the FEC functionality;
- and
- forwarding an encoded payload to a next layer.
