Traditionally, feedback has been mainly used in communication systems for retransmission and for channel prediction. Several recent results in network information theory have identified a new role for feedback: exploiting side information to mitigate interference. Due to the broadcast nature of communication media, information intended for one user is often received by other users. Feedback can be used to exploit this side information to improve the efficiency of future transmissions. The proposed work builds upon these results to come up with a theory unifying the existing isolated results as well as broadening to more scenarios of interest. It will also identify specific problems to solve for realizing this new role of feedback in practice. The goal is to close the gap between feedback research in information theory and the design of feedback mechanisms in practice.

传统上，反馈主要用于通信系统中的重传和信道预测。网络信息理论的一些最新成果已经确定了反馈的新作用：利用辅助信息来减轻干扰。由于通信媒体的广播性质，针对一个用户的信息经常被其他用户接收。 反馈可用于利用此辅助信息来提高未来传输的效率。拟议的工作以这些结果为基础，提出一种统一现有孤立结果并扩展到更多感兴趣场景的理论。它还将确定在实践中实现反馈这一新作用所需解决的具体问题。目标是缩小信息论反馈研究与实践中反馈机制设计之间的差距。
