DOI: 10.1109/mwc.001.2100136
Abstract: Channel reciprocity greatly facilitates downlink precoding in time-division duplexing (TDD) multiple-input multiple-output communications without the need for channel state information feedback. Recently, reconfigurable intelligent surfaces (RISs) have emerged as a promising technology to enhance the… read more here.

DOI: 10.1109/tcomm.2017.2676088
Abstract: Channel reciprocity in time-division duplexing (TDD) massive multiple-input multiple-output (MIMO) systems can be exploited to reduce the overhead required for the acquisition of channel state information (CSI). However, perfect reciprocity is unrealistic in practical systems… read more here.
