Fifth generation (5G) mobile communication systems have entered the stage of commercial development, providing users with new services and improved user experiences as well as offe…
On Secure Uplink Transmission in Hybrid RF-FSO Cooperative Satellite-Aerial-Terrestrial Networks
Yuanyuan Ma, Tiejun Lv, Gaofeng Pan +2
This work investigates the secrecy outage performance of the uplink transmission of a radio-frequency (RF)-free-space optical (FSO) hybrid cooperative satellite-aerial-terrestrial…
Cramér-Rao Bounds of Near-Field Positioning Based on Electromagnetic Propagation Model
Ang Chen, Li Chen, Yunfei Chen +3
The adoption of large-scale antenna arrays at high-frequency bands is widely envisioned in the beyond 5G wireless networks. This leads to the near-field regime where the wavefront…
Effect of Strong Time-Varying Transmission Distance on LEO Satellite-Terrestrial Deliveries
Yuanyuan Ma, Tiejun Lv, Tingting Li +3
In this paper, we investigate the effect of the strong time-varying transmission distance on the performance of the low-earth orbit (LEO) satellite-terrestrial transmission (STT) s…
Joint Communication and Sensing: Models and Potential of Using MIMO
Xinran Fang, Wei Feng, Yunfei Chen +2
The sixth-generation (6G) network is envisioned to integrate communication and sensing functions, so as to improve the spectrum efficiency (SE) and support explosive novel applicat…
Hierarchical-Absolute Reciprocity Calibration for Millimeter-wave Hybrid Beamforming Systems
Li Chen, Rongjiang Nie, Yunfei Chen +1
In time-division duplexing (TDD) millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems, the reciprocity mismatch severely degrades the performance of the h…
Cell-Free Satellite-UAV Networks for 6G Wide-Area Internet of Things
Chengxiao Liu, Wei Feng, Yunfei Chen +2
In fifth generation (5G) and beyond Internet of Things (IoT), it becomes increasingly important to serve a massive number of IoT devices outside the coverage of terrestrial cellula…
Enabling 5G on the Ocean: A Hybrid Satellite-UAV-Terrestrial Network Solution
Xiangling Li, Wei Feng, Jue Wang +3
Current fifth generation (5G) cellular networks mainly focus on the terrestrial scenario. Due to the difficulty of deploying communications infrastructure on the ocean, the perform…
A 6G White Paper on Connectivity for Remote Areas
Harri Saarnisaari, Sudhir Dixit, Mohamed-Slim Alouini +31
In many places all over the world rural and remote areas lack proper connectivity that has led to increasing digital divide. These areas might have low population density, low inco…
A Survey of Channel Modeling for UAV Communications
Aziz Altaf Khuwaja, Yunfei Chen, Nan Zhao +2
Unmanned aerial vehicles (UAVs) have gained great interest for rapid deployment in both civil and military applications. UAV communication has its own distinctive channel character…
