Hybrid Beamforming for mm-Wave Massive MIMO Systems with Partially Connected RF Architecture
Mohammad Majidzadeh, Jarkko Kaleva, Nuutti Tervo +3
To satisfy the capacity requirements of future mobile systems, under-utilized millimeter wave frequencies can be efficiently exploited by employing massive MIMO technology with hig…
On the Optimal Deployment of Power Beacons for Massive Wireless Energy Transfer
Osmel Martínez Rosabal, Onel L. Alcaraz López, Hirley Alves +2
Wireless energy transfer (WET) is emerging as an enabling green technology for Internet of Things (IoT) networks. WET allows the IoT devices to wirelessly recharge their batteries…
Intelligent Reflecting Surface Aided Vehicular Communications
Dilin Dampahalage, K. B. Shashika Manosha, Nandana Rajatheva +1
We investigate the use of an intelligent reflecting surface (IRS) in a millimeter-wave (mmWave) vehicular communication network. An intelligent reflecting surface consists of passi…
A Predictive Interference Management Algorithm for URLLC in Beyond 5G Networks
Nurul Huda Mahmood, Onel Alcaraz Lopez, Hirley Alves +1
Interference mitigation is a major design challenge in wireless systems,especially in the context of ultra-reliable low-latency communication (URLLC) services. Conventional average…
Ultra-low Latency, Low Energy and Massiveness in the 6G Era via Efficient CSIT-limited Schemes
Onel L. A. López, Nurul H. Mahmood, Hirley Alves +2
Channel state information (CSI) has been a key component in traditional wireless communication systems. This might no longer hold in future networks supporting services with string…
Deep Contextual Bandits for Fast Initial Access in mmWave Based User-Centric Ultra-Dense Networks
Insaf Ismath, K. B. Shashika Manosha, Samad Ali +2
Millimeter wave (mmWave) based multiple-input multiple-output (MIMO) capable user-centric (UC) ultra-dense (UD) networks are suggested to facilitate high throughput requirements of…
CSI-free vs CSI-based multi-antenna WET for massive low-power Internet of Things
Onel L. A. López, Nurul Huda Mahmood, Hirley Alves +1
Wireless Energy Transfer (WET) is a promising solution for powering massive Internet of Things deployments. An important question is whether the costly Channel State Information (C…
A 6G White Paper on Connectivity for Remote Areas
Harri Saarnisaari, Sudhir Dixit, Mohamed-Slim Alouini +31
In many places all over the world rural and remote areas lack proper connectivity that has led to increasing digital divide. These areas might have low population density, low inco…
Factory Automation: Resource Allocation of an Elevated LiDAR System with URLLC Requirements
Nalin Jayaweera, Dileepa Marasinghe, Nandana Rajatheva +1
Ultra-reliable and low-latency communications (URLLC) play a vital role in factory automation. To share the situational awareness data collected from the infrastructure as raw or p…
Ultra Reliable Communication via Optimum Power Allocation for HARQ Retransmission Schemes
Endrit Dosti, Mohammad Shehab, Hirley Alves +1
In this work, we develop low complexity, optimal power allocation algorithms that would allow ultra reliable operation at any outage probability target with minimum power consumpti…
Hierarchical User Clustering for mmWave-NOMA Systems
Dileepa Marasinghe, Nalin Jayaweera, Nandana Rajatheva +1
Non-orthogonal multiple access (NOMA) and mmWave are two complementary technologies that can support the capacity demand that arises in 5G and beyond networks. The increasing numbe…
Iterative Bayesian-based Localization Mechanism for Industry Verticals
Henrique Hilleshein, Carlos H. M. de Lima, Hirley Alves +1
We propose and evaluate an iterative localization mechanism employing Bayesian inference to estimate the position of a target using received signal strength measurements. The proba…
