Remarkable research activities and major advances have been occurred over the past
decade in multiuser multiple-input multiple-output (MU-MIMO) systems. Several …

Imagine a coverage area where each mobile device is communicating with a preferred set of
wireless access points (among many) that are selected based on its needs and cooperate to …

Massive multiple-input multiple-output (MIMO) is one of the most promising technologies for
the next generation of wireless communication networks because it has the potential to …

The use of multiple antennas at base stations is a key component in the design of cellular

This paper considers the sum spectral efficiency (SE) optimization problem in multi-cell
Massive MIMO systems with a varying number of active users. This is formulated as a joint …

This paper addresses the problem of energy-efficient resource allocation in the downlink of
a cellular orthogonal frequency division multiple access system. Three definitions of energy …

Massive multiple-input-multiple-output (MIMO) systems can suffer from coherent intercell
interference due to the phenomenon of pilot contamination. This paper investigates a two …

We consider online no-regret learning in unknown games with bandit feedback, where each
player can only observe its reward at each time—determined by all players' current joint …

Load balancing is an effective approach to address the spatial-temporal fluctuation problem
of mobile data traffic for cellular networks. The existing schemes that focus on channel …
