Feedback Design for Multi-Antenna K-Tier Heterogeneous Downlink Cellular Networks
IEEE Transactions on Wireless Communications, 17(6), 3861–3876.
author keywords: Heterogeneous cellular network; limited feedback; stochastic geometry
TL;DR:
In the non-cooperative case, the feedback is only useful in a particular tier if the mean interference is small enough; in the cooperative case, allocating more feedback to stronger intra-cluster BSs is efficient; and in both cases, the obtained solutions do not change depending on the instantaneous signal-to-interference ratio.
