Bio-Inspired Resource Allocation for Relay-Aided Device-to-Device Communications
Christoforos Vlachos, Hisham Elshaer, Jian Chen +2
The Device-to-Device (D2D) communication principle is a key enabler of direct localized communication between mobile nodes and is expected to propel a plethora of novel multimedia…
Interference-Aware Decoupled Cell Association in Device-to-Device based 5G Networks
Hisham Elshaer, Christoforos Vlachos, Vasilis Friderikos +1
Cell association in cellular networks is an important aspect that impacts network capacity and eventually quality of experience. The scope of this work is to investigate the differ…
Downlink and Uplink Cell Association with Traditional Macrocells and Millimeter Wave Small Cells
Hisham Elshaer, Mandar N. Kulkarni, Federico Boccardi +2
Millimeter wave (mmWave) links will offer high capacity but are poor at penetrating into or diffracting around solid objects. Thus, we consider a hybrid cellular network with tradi…
Why to Decouple the Uplink and Downlink in Cellular Networks and How To Do It
Federico Boccardi, Jeffrey Andrews, Hisham Elshaer +4
Ever since the inception of mobile telephony, the downlink and uplink of cellular networks have been coupled, i.e. mobile terminals have been constrained to associate with the same…
Capacity Analysis of Decoupled Downlink and Uplink Access in 5G Heterogeneous Systems
Katerina Smiljkovikj, Hisham Elshaer, Petar Popovski +4
Our traditional notion of a cell is changing dramatically given the increasing degree of heterogeneity in 4G and emerging 5G systems. Rather than belonging to a specific cell, a de…
Load & Backhaul Aware Decoupled Downlink/Uplink Access in 5G Systems
Hisham Elshaer, Federico Boccardi, Mischa Dohler +1
Until the 4th Generation (4G) cellular 3GPP systems, a user equipment's (UE) cell association has been based on the downlink received power from the strongest base station. Recent…
Downlink and Uplink Decoupling: a Disruptive Architectural Design for 5G Networks
Hisham Elshaer, Federico Boccardi, Mischa Dohler +1
Cell association in cellular networks has traditionally been based on the downlink received signal power only, despite the fact that up and downlink transmission powers and interfe…
