In millimeter wave (mmWave) communications, user position information can enable various
position-based communication services, such as resource allocation, beam tracking and …

As the mobile communication network evolves over the past few decades, localizing user
equipment (UE) has become an important network service. While localization in line-of-sight …

Channel charting is a data-driven baseband processing technique consisting in applying
unsupervised machine learning techniques to channel state information (CSI), with the …

The Internet of Things (IoT) has started to empower the future of many industrial and mass-
market applications. Localization techniques are becoming key to add location context to IoT …

In fifth-generation (5G) cellular networks, users feed back to the base station the index of the
precoder (from a codebook) to be used for downlink transmission. The precoder is strongly …

In this article, we focus on indoor direct positioning using a practical massive multiple-input
and multiple-output (MIMO) array with imperfections. First, the imperfect array needs to be …

In this work, we present a wireless localization method that operates on self-supervised and
unlabeled channel estimates. Our self-supervising method learns general-purpose channel …

A key operational requirement for Autonomous vehicles (AVs) is to have a highly reliable
positioning at the sub-meter lane-level accuracy. However, it is well-known that current …

This paper introduces an innovative deep learning-based approach for User Equipment
positioning in massive MIMO systems, enhanced by Flying Reconfigurable Intelligent …

The ever-growing demand for increased data rates, reduced latency, and more reliable
connectivity has driven the emergence of the fifth-generation (5G) wireless communication …
