Interference alignment with analog CSI feedback
2010 - MILCOM 2010 MILITARY COMMUNICATIONS CONFERENCE, 2010Interference alignment has been used to derive and realize the maximum multiplexing gain of the MIMO interference channel. Interference alignment requires some form of channel state information at the transmitter. This paper proposes analog CSI feedback as an alternative to limited feedback or reciprocity based alignment.

CSI feedback based on space-frequency compression
2020 IEEE 17th Annual Consumer Communications & Networking Conference (CCNC), 2020High-resolution Type II CSI feedback is a key differentiator between 4G (LTE) and 5G (NR). The large feedback overhead of Type II CSI reporting, however, is a bottleneck for UE implementations in real deployments. In this paper, a space-frequency compression based Type II CSI overhead reduction has been proposed. The system-level simulation results are

Reciprocity Aided CSI Feedback for Massive MIMO
2020 54th Asilomar Conference on Signals, Systems, and Computers, 2020A potential showstopper for reciprocity-based beamforming is that the uplink SNR often is much smaller than the downlink SNR, making it hard to estimate channels on the uplink. We analyze this problem by considering a "grid-of-beams world" with a finite number of possible channel realizations.

Feedback and delayed CSI can be as good as perfect CSI
2012 IEEE International Conference on Communications (ICC), 2012The degrees of freedom (DoF) region of the two-user MIMO interference channel (IC) is completely characterized in the presence of noiseless channel output feedback from each receiver to its respective transmitter and with the assumption of delayed channel state information (CSI) at the transmitters.

Low-complexity optimal CSI feedback in LTE
2013 IEEE 10th Consumer Communications and Networking Conference (CCNC), 2013The commercial deployment of 3GPP LTE systems is gaining increased momentum all over the globe. Achieving the ambitious spectral efficiency targeted by LTE poses significant technical challenges in mobile terminal modem development. In this work, we address the challenges associated with developing one of the key modules in the mobile terminal, the ...

CSI Compression and Feedback for Network MIMO
2015 IEEE 81st Vehicular Technology Conference (VTC Spring), 2015We consider the downlink of a multi-cell system where base stations and users are equipped with multiple antennas. Therein, a cluster of base stations employ joint transmission with linear zero-forcing beamforming based on compressed channel state information (CSI) feedback.
