Full-Duplex Wireless for 6G: Progress Brings New Opportunities and Challenges
Besma Smida, Ashutosh Sabharwal, Gabor Fodor +3
The use of in-band full-duplex (FD) enables nodes to simultaneously transmit and receive on the same frequency band, which challenges the traditional assumption in wireless network…
A Deep Reinforcement Learning-Based Resource Scheduler for Massive MIMO Networks
Qing An, Santiago Segarra, Chris Dick +2
The large number of antennas in massive MIMO systems allows the base station to communicate with multiple users at the same time and frequency resource with multi-user beamforming.…
Massive MIMO Channels with Inter-User Angle Correlation: Open-Access Dataset, Analysis and Measurement-Based Validation
Xu Du, Ashutosh Sabharwal
In practical propagation environments, different massive MIMO users can have correlated angles in spatial paths. In this paper, we study the effect of angle correlation on inter-us…
Balancing Queueing and Retransmission: Latency-Optimal Massive MIMO Design
Xu Du, Yin Sun, Ness B. Shroff +1
One fundamental challenge in 5G URLLC is how to optimize massive MIMO systems for achieving low latency and high reliability. A natural design choice to maximize reliability and mi…
Impact of Channel State Misreporting on Multi-user Massive MIMO Scheduling Performance
Zhanzhan Zhang, Yin Sun, Ashutosh Sabharwal +1
The robustness of system throughput with scheduling is a critical issue. In this paper, we analyze the sensitivity of multi-user scheduling performance to channel misreporting in s…
How to Mobilize mmWave: A Joint Beam and Channel Tracking Approach
Jiahui Li, Yin Sun, Limin Xiao +2
Maintaining reliable millimeter wave (mmWave) connections to many fast-moving mobiles is a key challenge in the theory and practice of 5G systems. In this paper, we develop a new a…
