Interference Alignment-Aided Base Station Clustering using Coalition Formation
Rasmus Brandt, Rami Mochaourab, Mats Bengtsson
Base station clustering is necessary in large interference networks, where the channel state information (CSI) acquisition overhead otherwise would be overwhelming. In this paper,…
Pilot Clustering in Asymmetric Massive MIMO Networks
Rami Mochaourab, Emil Björnson, Mats Bengtsson
We consider the uplink of a cellular massive MIMO network. Since the spectral efficiency of these networks is limited by pilot contamination, the pilot allocation across cells is o…
Linear Transceiver Optimization in Multicell MIMO Based on the Generalized Benders Decomposition
Rami Mochaourab, Mats Bengtsson
We study the maximum sum rate optimization problem in the multiple-input multiple-output interfering broadcast channel. The multiple-antenna transmitters and receivers are assumed…
Adaptive Pilot Clustering in Heterogeneous Massive MIMO Networks
Rami Mochaourab, Emil Björnson, Mats Bengtsson
We consider the uplink of a cellular massive MIMO network. Acquiring channel state information at the base stations (BSs) requires uplink pilot signaling. Since the number of ortho…
Overhead-Aware Distributed CSI Selection in the MIMO Interference Channel
Rami Mochaourab, Rasmus Brandt, Hadi Ghauch +1
We consider a MIMO interference channel in which the transmitters and receivers operate in frequency-division duplex mode. In this setting, interference management through coordina…
