Heterogeneous Partial Feedback Design in Heterogeneous OFDMA Cellular Networks

Modern heterogeneous networks have an inherent heterogeneous structure such as user densities and large scale channel effects that motivates this work on heterogeneous partial feedback design. In this paper, the authors address the partial feedback design issue in an OFDMA-based macro-pico cellular system employing the best-M partial feedback strategy. They consider the scenario with one picocell inside a macrocell, and investigate a scheduling policy which tracks the small scale channel effects in order to guarantee fairness among users as well as exploiting the multiuser diversity.
