On-the-fly Uplink Training and Pilot Code Sequence Design for Cellular Networks
Zekun Zhang, Chenwei Wang, Haralabos Papadopoulos
Cellular networks of massive MIMO base-stations employing TDD/OFDM and relying on uplink training for both downlink and uplink transmission are viewed as an attractive candidate fo…
On-the-fly Large-scale Channel-Gain Estimation for Massive Antenna-Array Base Stations
Chenwei Wang, Ozgun Y. Bursalioglu, Haralabos Papadopoulos +1
We propose a novel scheme for estimating the large-scale gains of the channels between user terminals (UTs) and base stations (BSs) in a cellular system. The scheme leverages TDD o…
Efficient C-RAN Random Access for IoT Devices: Learning Links via Recommendation Systems
Ozgun Y. Bursalioglu, Zheda Li, Chenwei Wang +1
We focus on C-RAN random access protocols for IoT devices that yield low-latency high-rate active-device detection in dense networks of large-array remote radio heads. In this cont…
SINR-Threshold Scheduling with Binary Power Control for D2D Networks
Mehrdad Kiamari, Chenwei Wang, A. Salman Avestimehr +1
In this paper, we consider a device-to-device communication network in which transmitter-receiver pairs are sharing spectrum with each other. We propose a novel but simple bina…
A novel alternative to Cloud RAN for throughput densification: Coded pilots and fast user-packet scheduling at remote radio heads
Ozgun Y. Bursalioglu, Chenwei Wang, Haralabos Papadopoulos +1
We consider wireless networks of remote radio heads (RRH) with large antenna-arrays, operated in TDD, with uplink (UL) training and channel-reciprocity based downlink (DL) transmis…
Harmonized Cellular and Distributed Massive MIMO: Load Balancing and Scheduling
Qiaoyang Ye, Ozgun Y. Bursalioglu, Haralabos C. Papadopoulos
Multi-tier networks with large-array base stations (BSs) that are able to operate in the "massive MIMO" regime are envisioned to play a key role in meeting the exploding wireless t…
