Dissertation in the field of communications engineering, Abdallah Bou Saleh, MSc
Abdallah Bou Saleh's dissertation takes place in Aalto University School of Electrical Engineering on Friday 4 April 2014 at 12 noon. The title of the thesis is "Inband Relaying in Long Term Evolution-Advanced Networks".
The stringent requirements of 4G access networks have triggered the embodiment of low-power relay nodes as part of the network infrastructure. Various types of relays are supported in IEEE 802.16m and LTE-Advanced considering different capabilities and backhauling characteristics. The matter of this study is the Layer 3 relay node whose wireless backhaul link and access link to the user operate on the same frequency band.
The thesis work addresses challenges pertaining to realizing such technology within the 3GPP LTE-Advanced context. A feasibility study of different relaying modes and a performance evaluation of inband relay deployments in different propagation environments are presented therein.
Further, the research work addresses wireless backhaul link limitation, resource allocation, load balancing and interference coordination in such multi-hop heterogeneous deployments. The significant system performance improvement achieved along with the energy efficiency of relay nodes proves that relaying is a viable enhancement to current radio access technologies.
