2. 1. Resource Allocation for Max-Min Fairness in Multi-Cell Massive MIMO

   Author : Trinh van Chien; Emil Björnson; Erik G. Larsson; Gabor Fodor; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Massive MIMO (multiple-input multiple-output) is considered as an heir of the multi-user MIMO technology and it has recently gained lots of attention from both academia and industry. By equipping base stations (BSs) with hundreds of antennas, this new technology can provide very large multiplexing gains by serving many users on the same time-frequency resources and thereby bring significant improvements in spectral efficiency (SE) and energy efficiency (EE) over the current wireless networks.

4. 2. Mathematical Models and Algorithms for Wireless Network Design and Optimization

   Author : Yuan Li; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; max-min flow; directional antenna; optimization; integer programming; cellular backhaul network design; delay minimization; SINR; compatible set;

   Abstract : Optimization techniques always play an important role in designing high-performance wireless systems. This presented thesis studies a selected set of optimization problems for different kinds of wireless networks, making use of mathematical programming techniques to find optimal solutions and of efficient heuristics to find near-optimal solutions.

5. 3. Efficient Use of Exponential Size Linear Programs

   Author : Lukas Polacek; Johan Håstad; Nikhil Bansal; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; approximation algorithms; linear programming; allocation problems; Computer Science; Datalogi;

   Abstract : In the past decades, linear programming (LP) has been successfully used to develop approximation algorithms for various optimization problems. In particular, the so-called assignment LP has lead to substantial progress for various allocation problems, including scheduling unrelated parallel machines. READ MORE

6. 4. Optimization of Joint Cell, Channel and Power Allocation in Wireless Communication Networks

   Author : Mikael Fallgren; Anders Forsgren; Zhi-Quan (Tom) Luo; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless multicell networks; Optimization; OFDMA; Shannon capacity; Complexity; NP-hard; Relays; Allocation problems; Heuristic algorithms;

   Abstract : In this thesis we formulate joint cell, channel and power allocation problems within wireless communication networks. The objectives are to maximize the user with mini- mum data throughput (Shannon capacity) or to maximize the total system throughput, referred to as the max-min and max-sum problem respectively.
