In this article the cross-platform software and hardware solution for LTE key performance indicators optimization are developed. There are two important conflicting indicators are explained and optimized — LTE user's throughput and cell throughput versus different power control parameter settings such as nominal power per resource block and alpha for fractional power control. The results graphically...
Small cells are beneficial for both users and operators to improve communication quality. The femtocell is one type of small cell used for indoor coverage. Enterprise femtocell installation inevitably produces intralayer and interlayer interference management issues. Enterprise femtocell optimization and indoor propagation modeling are built in this work based on the communications environment characteristics...
In this paper we study uplink open loop power control (OLPC) optimization for co-channel Heterogenous Network (HetNet) scenarios with macro and pico cells under fractional load conditions. Two methods for automatic OLPC optimization are proposed, motivated and compared against manual approach. It is found that the OLPC parameters at the pico-layer can be computed as a function of the OLPC parameters...
Self-adaptation is a key factor for the future evolution of mobile networks due to their increasing complexity and required management efforts. In this paper, we propose an autonomous self-adaptive scheme based on Harmony Search (HS) Algorithm for radio resource management and interference coordination. One of the main strong points of the proposed scheme is that the computations are independent on...
LTE (Long Term Evolution) supports QoS (Quality of Service) with several service classes. For each class of traffic, a big difference exists on BER (Bit Error Rate) requirement. This leads to a considerable difference in transmission power for various classes of traffic. In this paper, a novel scheduler is designed and proposed for LTE which supports CoS (Class of Service) with the consideration of...
