UAV-to-Device Underlay Communications: Age of Information Minimization by Multi-agent Deep Reinforcement Learning
Fanyi Wu, Hongliang Zhang, Jianjun Wu +3
In recent years, unmanned aerial vehicles (UAVs) have found numerous sensing applications, which are expected to add billions of dollars to the world economy in the next decade. To…
Cellular UAV-to-Device Communications: Trajectory Design and Mode Selection by Multi-agent Deep Reinforcement Learning
F. Wu, H. Zhang, J. Wu +1
In the current unmanned aircraft systems (UASs) for sensing services, unmanned aerial vehicles (UAVs) transmit their sensory data to terrestrial mobile devices over the unlicensed…
Device-to-Device Communications Underlaying Cellular Networks: To Use Unlicensed Spectrum or Not?
Fanyi Wu, Hongliang Zhang, Boya Di +2
In this paper, we consider device-to-device (D2D) communications as an underlay to the cellular networks over both licensed and unlicensed spectrum, where Long Term Evolution (LTE)…
Full-duplex Amplify-and-Forward Relaying: Power and Location Optimization
Shuai Li, Kun Yang, Mingxin Zhou +4
In this paper, we consider a full-duplex (FD) amplify-and-forward (AF) relay system and optimize its power allocation and relay location to minimize the system symbol error rate (S…
X-duplex Relaying: Adaptive Antenna Configuration
Shuai Li, Mingxin Zhou, Jianjun Wu +3
In this letter, we propose a joint transmission mode and transmit/receive (Tx/Rx) antenna configuration scheme referred to as X-duplex in the relay network with one source, one amp…
On the Performance of X-Duplex Relaying
Shuai Li, Mingxin Zhou, Jianjun Wu +3
In this paper, we study a X-duplex relay system with one source, one amplify-and-forward (AF) relay and one destination, where the relay is equipped with a shared antenna and two r…
