Optimal Time Reuse in Cooperative D2D Relaying Networks
Zhaowei Zhu, Shengda Jin, Yu Zeng +2
Device-to-device (D2D) communication has become one important part of the 5G cellular networks particularly due to the booming of proximity-based applications, e.g. D2D relays. How…
A Scalable Framework for CSI Feedback in FDD Massive MIMO via DL Path Aligning
Xiliang Luo, Penghao Cai, Xiaoyu Zhang +2
Unlike the time-division duplexing (TDD) systems, the downlink (DL) and uplink (UL) channels are not reciprocal anymore in the case of frequency-division duplexing (FDD). However,…
Flexible Pilot Contamination Mitigation with Doppler PSD Alignment
Xiliang Luo, Xiaoyu Zhang
Pilot contamination in the uplink (UL) can severely degrade the channel estimation quality at the base station (BS) in a massive multi-input multi-output (MIMO) system. Thus, it is…
Pilot Decontamination via PDP Alignment
Xiliang Luo, Xiaoyu Zhang, Hua Qian +1
In this paper, we look into the issue of intra-cell uplink (UL) pilot orthogonalization and schemes for mitigating the inter-cell pilot contamination with a realistic massive multi…
