A Survey on Multiple-Antenna Techniques for Physical Layer Security (2017, background): “However, in practice, the transmitter in multiple-antenna systems usually obtain only partial CSI through information feedback from the receiver(s) [74]–[76] in frequency division duplex (FDD) systems or directly using channel reciprocity [77]–[79] in time division duplex (TDD) systems.”
Millimeter-Wave Massive MIMO Communication for Future Wireless Systems: A Survey (2018, methodology): “With TDD, CSI is obtained using uplink training of pilots, as the downlink channel matrix is assumed a conjugate of the uplink channel matrix [21], [29], [35].”
A Comprehensive Survey of Pilot Contamination in Massive MIMO—5G System (2016, background): “This eliminates the need for feedback and allows for acquisition of CSI through reciprocity of wireless medium with UL training signals [73].”
Massive MIMO: An Introduction (2015, unknown): “An FDD system requires considerably more time for training than a TDD system [19].”

This generally entails the need of performing complex signal processing tasks at the analog repeater during JOURNAL OF COMMUNICATIONS SURVEYS AND TUTORIALS 12 the channel estimation procedure [96], [97], [98], [99]. However, in order to simplify the repeater and reduce both its power consumption a”
Multiuser MIMO Achievable Rates With Downlink Training and Channel State Feedback (2007, methodology): “The power scaling βfb corresponds to the number of channel uses per channel coefficient (we require βfb ≥ 1 so that each coefficient is transmitted at least once), assuming that transmission in the feedback channel has per-symbol power P (averaged over frames) and that the channel state vector is mo”
Pilot Contamination and Precoding in Multi-Cell TDD Systems (2009, background): “Arguably, this is one of the best advantages of a TDD architecture, as it eliminates the need f or feedback, and uplink training together with the reciprocity of the wireless medium [11] is sufficient to provide us with the desired CSI.”
