BDMA for Millimeter-Wave/Terahertz Massive MIMO Transmission with Per-Beam Synchronization
Li You, Xiqi Gao, Geoffrey Ye Li +2
We propose beam division multiple access (BDMA) with per-beam synchronization (PBS) in time and frequency for wideband massive multiple-input multiple-output (MIMO) transmission ov…
An Overview of Sustainable Green 5G Networks
Qingqing Wu, Geoffrey Ye Li, Wen Chen +2
The stringent requirements of a 1,000 times increase in data traffic and one millisecond round trip latency have made limiting the potentially tremendous ensuing energy consumption…
Device-to-device Cooperation in Massive MIMO Systems with Cascaded Precoding
Yinsheng Liu, Geoffrey Ye Li, Wei Han
This paper investigates user cooperation in massive multiple-input multiple-output (MIMO) systems with cascaded precoding. The high-dimensional physical channel in massive MIMO sys…
Energy-Efficient Small Cell with Spectrum-Power Trading
Qingqing Wu, Geoffrey Ye Li, Wen Chen +1
In this paper, we investigate spectrum-power trading between a small cell (SC) and a macro cell (MC), where the SC consumes power to serve the macro cell users (MUs) in exchange fo…
Quantization and Feedback of Spatial Covariance Matrix for Massive MIMO Systems with Cascaded Precoding
Yinsheng Liu, Geoffrey Ye Li, Wei Han
In this paper, we investigate the quantization and the feedback of downlink spatial covariance matrix for massive multiple-input multiple-output (MIMO) systems with cascaded precod…
Low-Complexity Recursive Convolutional Precoding for OFDM-based Large-Scale Antenna System
Yinsheng Liu, Geoffrey Ye Li, Wei Han +1
Large-scale antenna (LSA) has gained a lot of attention recently since it can significantly improve the performance of wireless systems. Similar to multiple-input multiple-output (…
Energy- and Spectral-Efficiency Tradeoff in Full-Duplex Communications
Dingzhu Wen, Guanding Yu, Rongpeng Liy +2
This paper investigates the tradeoff between energyefficiency (EE) and spectral-efficiency (SE) for full-duplex (FD) enabled cellular networks.We assume that small cell base statio…
Spectrum-Power Trading for Energy-Efficient Small Cell
Qingqing Wu, Geoffrey Ye Li, Wen Chen +1
This paper investigates spectrum-power trading be- tween a small cell (SC) and a macro-cell (MC), where the SC consumes power to serve the macro-cell users (MUs) in exchange for so…
Comparison of OFDM and Single-Carrier for Large-Scale Antenna Systems
Yinsheng Liu, Geoffrey Ye Li, Wei Han
Large-scale antenna (LSA) or massive multiple-input multiple-output (MIMO) has gained a lot of attention due to its potential to significantly improve system throughput. As a natur…
Fundamental Green Tradeoffs: Progresses, Challenges, and Impacts on 5G Networks
Shunqing Zhang, Qingqing Wu, Shugong Xu +1
With years of tremendous traffic and energy consumption growth, green radio has been valued not only for theoretical research interests but also for the operational expenditure red…
Full-Duplex Cellular Networks: It Works!
Rongpeng Li, Yan Chen, Geoffrey Ye Li +1
Full-duplex (FD) communications with bidirectional transmitting and receiving at the same time and frequency radio resource have long been deemed a promising way to boost spectrum…
