Remote Channel Inference for Beamforming in Ultra-Dense Hyper-Cellular Network
Sheng Chen, Zhiyuan Jiang, Jingchu Liu +4
In this paper, we propose a learning-based low-overhead channel estimation method for coordinated beamforming in ultra-dense networks. We first show through simulation that the cha…
Statistical Multiplexing Gain Analysis of Heterogeneous Virtual Base Station Pools in Cloud Radio Access Networks
Jingchu Liu, Sheng Zhou, Jie Gong +2
Cloud radio access network (C-RAN) is proposed recently to reduce network cost, enable cooperative communications, and increase system flexibility through centralized baseband proc…
Topic Model Based Behaviour Modeling and Clustering Analysis for Wireless Network Users
Bingjie Leng, Jingchu Liu, Huimin Pan +2
User behaviour analysis based on traffic log in wireless networks can be beneficial to many fields in real life: not only for commercial purposes, but also for improving network se…
A Block Regression Model for Short-Term Mobile Traffic Forecasting
Huimin Pan, Jingchu Liu, Sheng Zhou +1
Accurate mobile traffic forecast is important for efficient network planning and operations. However, existing traffic forecasting models have high complexity, making the forecasti…
Seeing the Unobservable: Channel Learning for Wireless Communication Networks
Jingchu Liu, Ruichen Deng, Sheng Zhou +1
Wireless communication networks rely heavily on channel state information (CSI) to make informed decision for signal processing and network operations. However, the traditional CSI…
Redesigning Fronthaul for Next-Generation Networks: Beyond Baseband Samples and Point-to-Point Links
Jingchu Liu, Shugong Xu, Sheng Zhou +1
The fronthaul (FH) is an indispensable enabler for 5G networks. However, the classical fronthauling method demands for large bandwidth, low latency, and tightly synchronized on the…
Graph-based Framework for Flexible Baseband Function Splitting and Placement in C-RAN
Jingchu Liu, Sheng Zhou, Jie Gong +2
The baseband-up centralization architecture of radio access networks (C-RAN) has recently been proposed to support efficient cooperative communications and reduce deployment and op…
CONCERT: A Cloud-Based Architecture for Next-generation Cellular Systems
Jingchu Liu, Tao Zhao, Sheng Zhou +2
Cellular networks are one of the corner stones of our information-driven society. However, existing cellular systems have been seriously challenged by the explosion of mobile data…
On the Statistical Multiplexing Gain of Virtual Base Station Pools
