RESEARCH Interference
Aware and Fair Cell Association, User Scheduling, and Resource Allocation in
Next Generation Ultra Dense Heterogeneous Communication Networks
In the
ongoing project, it is aimed to investigate and propose original solutions
for user-cell association, priority based scheduling, and fair resource
allocation problems for next generation ultra-dense heterogeneous communication
networks. Latest results, publications and events will be shared in this web
site. In
existing cellular communication systems, structures and capabilities of cells
and base stations are homogeneous and a single base station serves a large
cell. Hence, inter-cell interference occurs especially on edges of cells and
cell edge users can experience service outage. In next generation
communication systems, heterogeneous structures with different capabilities
and coverage areas will be used instead of homogeneous cells. Heterogeneous
networks that existed since fourth generation communication systems are
transforming into ultra-dense heterogeneous networks in 5G and beyond
systems. In the
project, it is aimed to investigate and propose original solutions for
user-cell association, priority based scheduling, and fair resource
allocation problems for next generation ultra-dense heterogeneous
communication networks. Proposed solutions will also be supported by
computer-based simulation studies. Outputs are expected to produce and guide
the required principles for cell allocation, scheduling, and resource
allocation for next generation networks. The
proposed interference aware, latency aware, fair, multi-connectivity enabled,
and joint uplink-downlink optimization designs will be investigated for the
first time in the literature as a whole for ultra-dense heterogeneous
networks. Therefore, the developed optimum and near-optimum principles and
techniques will close the gap in the relevant literature. Less comprehensive
problems could not be solved using traditional optimization techniques in the
literature, however, it is predicted that the interference regulated
water-filling method that we introduced to the literature will be effective
for the solution of the proposed problems. The
project is a combination of two work packages that are complementary. First
work package includes user-cell association and scheduling and second work
package includes resource allocation studies. Outputs of both packages will
have up-to-date and original designs. Work packages are divided into sub-work
packages with appropriate targets, measures and deadlines. If optimum
solutions could not be found, then either suboptimum solutions will be found
or heuristic algorithms will be used. |
