Abstract
Apparatus, methods, and computer-readable media for an error correction technique that identifies transmission errors and corrective actions to maintain a link are disclosed herein. An example method of wireless communications includes receiving a first PDU comprising at least one of a SEQN bit or a packet counter value. The example method includes determining whether a value of the SEQN bit of the received first PDU is an expected SEQN or an unexpected SEQN. The example method includes calculating a MIC of the received first PDU. The example method includes determining whether the received first PDU is a re-transmission of a previous PDU or the received first PDU comprising errors. The example method includes transmitting an ACK or a NACK in response to the determination of whether the first PDU is the re-transmission of the previous PDU or the first PDU comprising errors.
