Abstract: Systems and methods are provided to improve data transmission efficiency over a network. The improvements are achieved by reducing the redundancy in the data representation. The data is divided into a plurality of data portions. The data portions are used to encode a plurality of compressed data portions, wherein the compressed data portions correspond to a subset of the data portions and comprise less redundant data than the subset of the data portions. The compressed data portions are also encoded in accordance with data in the remaining data portions. The compressed data portions are transmitted instead of the subset of the data portions with the remaining data portions according to a sequence of data portions. Each of the compressed data portions is transmitted upon receiving an acknowledgment (ACK) message that indicates successful transmission of a previous data portion or compressed data portion in the sequence of data portions.

Abstract: Historical decoding in accordance with signal interference cancellation (SIC) or joint processing may reduce the amount of data that is re-transported across a network following an unsuccessful attempt to decode a data transmission. In one example, historical decoding is performed in accordance with interference cancellation by communicating information related to interfering data (rather than information related to serving data) following a served receiver's unsuccessful attempt to decode an interference signal. The information related to the interfering data may be the information bits carried by the earlier interfering data transmission or parity information (e.g., forward error correction (FEC) bits, etc.) related to the earlier interfering data transmission.

Abstract translation: 根据信号干扰消除（SIC）或联合处理的历史解码可以减少在不成功解码数据传输的尝试之后通过网络重新传输的数据量。 在一个示例中，在服务的接收机的不成功尝试解码干扰信号之后，通过传送与干扰数据相关的信息（而不是与服务数据相关的信息），根据干扰消除来执行历史解码。 与干扰数据相关的信息可以是与较早的干扰数据传输相关的早期干扰数据传输或奇偶校验信息（例如，前向纠错（FEC）比特等）携带的信息比特。
