Channel quantization design in multiuser MIMO systems: Asymptotic versus practical conclusions
Feedback of channel state information (CSI) is necessary to achieve high throughput and low outage probability in multiuser multiantenna systems. There are two types of CSI: directional and quality information. Many papers have analyzed the importance of these in asymptotic regimes. However, we show that such results should be handled with care, as very different conclusions can be drawn depending on the spatial correlation and number of users. Therefore, we propose a quantization framework and evaluate the tradeoff between directional and quality feedback under practical conditions.
