Table 4 The size of feedback used in each MU-MIMO system
From: Low-complexity multiuser MIMO downlink system based on a small-sized CQI quantizer
System | Feedback organization | Total feedback |
|---|---|---|
RBF w. QBC or MESC | CDI: 2 bits, CQI: 1 or 2 bits | 3 or 4 bits |
SUS-ee w. QBC or MESC | CDI: 5,6,7 or 8 bits, CQI: 2 bits | 7,8,9 or 10 bits |
