Adaptive payload extraction and retransmission in wireless data communications with error aggregations
Provided are systems and methods for adaptive payload extraction and retransmission in wireless data communications. An example method commences with transmitting a network packet to a receiver via a communication channel. The method further includes receiving a further network packet including a further payload. The method continues with determining, based on the payload and the further payload, an error vector. The method includes generating, based on the error vector, a plurality of indices. An index of the plurality of indices corresponds to a portion of a plurality of non-overlapping portions of the payload. The method further continues with selecting, based on the error vector, at least one index from the plurality of indices. The method includes sending, to the receiver via the communication channel, a further network packet. The further network packet includes the selected index and a portion of the payload corresponding to the selected index.
