Abstract:
1. A method of compensating for information not received in a communication system, the method comprising: creating 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, wherein N is greater than K and K is greater than, and wherein the source signal can be decoded from any K protocol data units; transmitting, at a transmitter, 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 wherein each protocol data unit is transmitted independently of other transmitted protocol data units; determining 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, wherein the receiver only acknowledges a successfully decoded source signal rather than individual protocol data units; transmitting, at the transmitter, 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; receiving, from the receiver, an acknowledgement indicating the receiver has successfully decoded the source signal after transmitting the second set of the protocol data units; and terminating transmission of the protocol data units based on the receiving of the acknowledgement from the receiver, wherein 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.
