Concurrent Channel Probing and Data Transmission in Full-duplex MIMO Systems
Zhenzhi Qian, Fei Wu, Zizhan Zheng +2
An essential step for achieving multiplexing gain in MIMO downlink systems is to collect accurate channel state information (CSI) from the users. Traditionally, CSIs have to be col…

Achieving Delay Rate-function Optimality in OFDM Downlink with Time-correlated Channels
Zhenzhi Qian, Bo Ji, Kannan Srinivasan +1
There have been recent attempts to develop scheduling schemes for downlink transmission in a single cell of a multi-channel (e.g., OFDM-based) cellular network. These works have be…
