Optimizing Feedback User Selection for Standalone U-LTE Networks With Randomly Delayed CSI

Accurate channel state information (CSI) plays a critical role in channel-aware transmissions. However, in standalone long-term evolution networks in unlicensed spectrum, it is challenging to obtain accurate CSI timely via intermittent and random channel access. In this letter, we propose an optimiz...
