Titre : Exploring Gibbs sampling techniques for mobility in Macro/Small
cells
Subject :
The need for bandwidth and the incitations to reduce power consumption
leads to the reduction of cells' size in cellular networks. This allows
reducing the distance between mobile and base station thus increasing
the capacity. This reduction implies problems for cells organization and
network deployment, especially due to the cells interference. Moreover,
the evolution of next generation radio access networks such as LTE,
LTE-advanced, is characterized by an increasingly distributed
architecture (also denoted as flat architecture). This allows reducing
the network complexity, the delays, and the signalling load. In a flat
architecture network, many Radio Resource Management (RRM) functions are
located within the base stations. Examples are mobility management,
packet scheduling and different resource allocation functionalities
(e.g. transmission powers etc.). A similar trend is expected in
Self-Organizing Network (SON) entities, such as mobility optimization,
interference management etc. It is recalled that in 2G and 3G networks,
a more centralized operation of resource management is used. For
example, in UMTS 3G networks, mobility management is performed in the
Radio Network Controller (RNC) to which a large number on Node Bs are
connected.
The objective of this thesis is to develop the algorithms and solutions
required to allow Small Cells Network (SCN) deployment. This thesiswill
explore the Gibbs Sampling techniques in order to propose different
architectures allowing the Gibbs sampler algorithms to obtain an optimal
resource allocation in a distributed manner and in different scenarios.
In this thesis, we will exploit the Gibbs sampling for several scenarios
?
