The commercial fifth-generation (5G) wireless communications networks have already been
deployed with the aim of providing high data rates. However, the rapid growth in the number …

Millimeter-wave communication with high throughput and high reliability is poised to be a
gamechanger for V2X and VR applications. However, mmWave links are notorious for low …

Millimeter-wave (mmW) spectrum is a major candidate to support the high data rates of 5G
systems. However, due to directionality of mmW communication systems, misalignments …

5G millimeter-wave (mmW) systems rely on electronically steerable antenna arrays to
support directional communications. Directionality complicates the initial access (IA) …

Modern mmWave systems have limited scalability due to inflexibility in performing frequency
multiplexing. All the frequency components in the signal are beamformed to one direction …

In this article, we propose MAMBA, a restless multi-armed bandit framework for beam
tracking in directional millimeter-wave (mmW) cellular systems. Instead of relying on explicit …

Millimeter-wave (mmWave) communication is an important technology to meet the demand
of high data rate in sixth generation (6G) wireless networks. Blockage is a major obstacle to …

Millimeter-wave communication has the potential to deliver orders of magnitude increases in
mobile data rates. A key design challenge is to enable rapid beam alignment with phased …

We study the initial beam acquisition problem in millimeter wave (mm-wave) networks from
the perspective of best arm identification in multi-armed bandits (MABs). For the stationary …

In this paper, we study the beam synthesis and management methods for the phased
antenna array-based wireless communications systems, eg, 5 G mmWave communications …
