Dynamic Power Control for Packets with Deadlines
Emmanouil Fountoulakis, Nikolaos Pappas, Qi Liao +2
Wireless devices need to adapt their transmission power according to the fluctuating wireless channel in order to meet constraints of delay sensitive applications. In this paper, w…
Resource Optimization with Flexible Numerology and Frame Structure for Heterogeneous Services
Lei You, Qi Liao, Nikolaos Pappas +1
We explore the potential of optimizing resource allocation with flexible numerology in frequency domain and variable frame structure in time domain, in presence of services with di…
An Examination of the Benefits of Scalable TTI for Heterogeneous Traffic Management in 5G Networks
Emmanouil Fountoulakis, Nikolaos Pappas, Qi Liao +2
The rapid growth in the number and variety of connected devices requires 5G wireless systems to cope with a very heterogeneous traffic mix. As a consequence, the use of a fixed TTI…
Joint Optimization of Coverage, Capacity and Load Balancing in Self-Organizing Networks
Qi Liao, Daniyal Amir Awan, Slawomir Stanczak
This paper develops an optimization framework for self-organizing networks (SON). The objective is to ensure efficient network operation by a joint optimization of different SON fu…
Dynamic Joint Uplink and Downlink Optimization for Uplink and Downlink Decoupling-Enabled 5G Heterogeneous Networks
Qi Liao, Danish Aziz, Slawomir Stanczak
The concept of user-centric and personalized service in the fifth generation (5G) mobile networks encourages technical solutions such as dynamic asymmetric uplink/downlink resource…
