Joint Downlink Cell Association and Bandwidth Allocation for Wireless Backhauling in Two-Tier HetNets with Large-Scale Antenna Arrays
Ning Wang, Ekram Hossain, Vijay K. Bhargava
The problem of joint downlink cell association (CA) and wireless backhaul bandwidth allocation (WBBA) in two-tier cellular heterogeneous networks (HetNets) is considered. Large-sca…
Distributed Resource Allocation in 5G Cellular Networks
Monowar Hasan, Ekram Hossain
The 5G cellular wireless systems will have a multi-tier architecture consisting of macrocells, different types of licensed small cells and D2D networks to serve users with differen…
Distributed Resource Allocation for Relay-Aided Device-to-Device Communication: A Message Passing Approach
Monowar Hasan, Ekram Hossain
Device-to-device (D2D) communication underlaying cellular wireless networks is a promising concept to improve user experience and resource utilization by allowing direct transmissi…
Analytical Modeling of Mode Selection and Power Control for Underlay D2D Communication in Cellular Networks
Hesham ElSawy, Ekram Hossain
Device-to-device (D2D) communication enables the user equipments (UEs) located in close proximity to bypass the cellular base stations (BSs) and directly connect to each other, and…
Tier-Aware Resource Allocation in OFDMA Macrocell-Small Cell Networks
Amr Abdelnasser, Ekram Hossain, Dong In Kim
We present a joint sub-channel and power allocation framework for downlink transmission an orthogonal frequency-division multiple access (OFDMA)-based cellular network composed of…
Location-Aware Cross-Tier Coordinated Multipoint Transmission in Two-Tier Cellular Networks
Ahmed Hamdi Sakr, Ekram Hossain
Multi-tier cellular networks are considered as an effective solution to enhance the coverage and data rate offered by cellular systems. In a multi-tier network, high power base sta…
