    • A method of compensating for information not received in a communication system and a node are disclosed. The node comprises a processor configured to create an encoded signal comprising N protocol data units from a source signal comprising K protocol data units using a forward error correction technique prior to transmitting any of the N protocol data units with N is greater than K and K is greater than one, and the source signal can be decoded from any K protocol data units; and a transmitter operatively coupled to the processor and configured to transmit a first set of protocol data units comprising at least K but less than N of the protocol data units of the encoded signal, wherein each protocol data unit in the first set of protocol data units includes an indication of a total number of protocol data units sufficient to decode the encoded signal, and each protocol data unit is transmitted independently of other transmitted protocol data units. The processor is further configured to determine the receiver has not successfully decoded the source signal from the transmitted first set of protocol data units based upon not receiving an acknowledgement from the receiver. The receiver only acknowledges a successfully decoded source signal rather than individual protocol data units. The transmitter is further configured to transmit a second set of protocol data units comprising unsent protocol data units of the encoded signal to the receiver based on the determining the receiver has not successfully decoded the source signal from the transmitted first set of protocol data units; receive, from the receiver, an acknowledgement indicating the receiver has successfully decoded the source signal after the second set of the protocol data units was transmitted; and terminate transmission of the protocol data units based on the receiving of the acknowledgement from the receiver successfully decoding the source signal. At least one protocol data unit of the encoded signal is not transmitted to the receiver, and wherein a total number of protocol data units sent to transmit the source signal is less than N. A system comprises an access point comprising a receiver configured to decode an encoded signal and the above described node is disclosed.
