In this paper, we consider limited feedback systems for FDD large-scale(massive) MIMO. A new codebook-based framework for multiuser (MU) MIMO downlinksystems is introduced and then compared with an ideal non-codebook basedsystem. We are particularly interested in the less-known finite-rate feedbackregime where the number $M$ of transmit antennas and the number of users are ofthe same order of magnitude and $M$ is large but finite, which is a typicalscenario of large-scale MIMO. We provide new findings in this regime andidentify some benefits of the new framework in terms of scheduling gain anddownlink dedicated pilot overhead.
