Abstract

An example method may include receiving a wireless packet from a sender node at a receiver node that includes a PHY and a MAC. The wireless packet may include multiple codewords. The method may include error checking the codewords at the PHY of the receiver node for codeword-level errors. The method may include generating multiple MPDUs from the codewords. The method may include error checking the MPDUs at the MAC of the receiver node for MPDU-level errors. The method may include generating two-tier feedback based on the error checking at the PHY and the MAC of the receiver node. The method may include sending the two-tier feedback to the sender node.
