The 4G++ Project Overview

To achieve the objectives the 4G++ project was organized into six work packages (WPs) as shown below.

 

Work Package 1: Project Management

The main objective of the project management WP is to perform overall project government and to establish and maintain a communication and follow-up infrastructure. This includes the following detailed objectives:

  1. Monitoring, tracking and controlling deviations due to progress, resources allocation, scheduling and changes.
  2. Managing the project according to approved plans.
  3. Ensuring that the required reports are prepared and delivered in a timely manner.

 

Tasks

This work package will involve the following tasks:

  1. Planning & scheduling: collect input and needs for changes, define and check consequences according to resources, scheduling and objectives.
  2. Progress monitoring: measuring effort, schedules, milestones, and assessment of deliverables on the WP level.
  3. Hold monthly project meetings for all members.
  4. Coordination with the funding agency including progress reports preparation and delivery.
  5. Coordinating with the university administration for contracts, purchases, expenditures, reimbursements, etc.
  6. Managing the project technical activities including assigning tasks and managing the research assistants and monitoring their progress.
  7. Contingency planning and strategic planning for the project.
  8. Explore opportunities for exploitation of the project results.

 

Work Package 2: Development of Accurate LTE/LTE-Advanced System Model

WP 2 will construct an accurate simulation model for an LTE/LTE-Advanced wireless system consisting of macro-cells, femto-cells, relay nodes, and UE’s. An accurate propagation channel model based on the WINNER II channel models will be used. Different channel models shall be used to account for UE’s mobility, slow/fast channel fading, and indoor/outdoor environments.

Tasks

This work package is divided into the following tasks:

  1. Construction of an Accurate LTE/LTE-Advanced System Model
  2. Validation of the LTE/LTE-Advanced System Model

 

Work Package 3: Channel-Aware Radio Resource Management and Scheduling in LTE and LTE-Advanced Systems

WP 3 will investigate, propose, and evaluate schemes for channel-aware scheduling in downlink and uplink directions in LTE/LTE-Advanced. Moreover, it will assess how a mobile operator can tune the parameters of the scheduling to meeting the requirements of different tiers of users (business, premium, regular) with different connection classes (real-time versus non-real-time). An important objective is to reduce interference in the uplink by using the minimum possible power and to reduce downlink interference at cell edges. Hence, constraints in maximum power usage will be explicitly considered in the formulation.

Tasks

This work package is divided into the following tasks:

  1. Uplink Channel-Aware Scheduling Schemes
  2. Coordinated Radio Resource Allocation in CoMP
  3. Radio Resource Management with Carrier-Aggregation
Work Package 4: Inter-Cell Interference Coordination (ICIC)

WP 4 will tackle the area of ICIC. The objective is to devise efficient schemes for RRM in a multi-cells scenario. We consider here three problems: 1) The design of autnonomous allocation scheme based on limiting interference contribution of each base-station, 2) Practical Interference Alignment Schemes, and 3) Autonomous RRM for femto-cells. This study would also be relevant for support of LTE Self-Organized Networks (SON) functionality. The results should be very useful for exploitation by mobile operators.

Tasks

This work package is divided into the following tasks:

  1. Multi-cell Uplink Resource Allocation Problem under the Interference Limit Constraint
  2. Interference Alignment Schemes for LTE-A
  3. Autonomous Radio Resource Management for Femto-cells
  4. Detailed Study of CoMP using Realistic Assumptions and Channel Models
Work Package 5: Exploitation of Relaying and Network Coding in LTE-Advanced for Enhanced Capacity and Coverage

WP 5 will tackle the area of relays and network coding for capacity boosting in LTE-Advanced. Since this area is the most challenging and least developed area in the proposal, it is to be noted that dates and deliverables are only tentative since the results of each stage of the research will determine and drive to a large extent the work to be done in the next stage. The objective is to explore how these two techniques can be co-exploited to provide high spectral efficiency.

Tasks

This work package is divided into the following tasks:

  1. Relay Structure and Dynamics
  2. Practical Network Coding Algorithms for Relay Enhanced Cells

 

Work Package 6: Dissemination

WP 6 is a vertical work package that will serve all technical work packages. The objectives of this work package are to provide means for disseminating the project results and to pursue tracks for exploitation of the results. It shall attain to timely delivery of the periodical progress reports with NTRA and the submission and follow-up on papers to be published in international conferences and journals. A number of contributions are also planned to be submitted for 3GPP LTE-Advanced working groups. The work package shall also periodically identify and document the possible ideas that can be patented. We also plan to organize two local 1-day workshops to share the results with the local/regional research community. The following means are foreseen for dissemination:

  1. Publish research results in selective academic venues. This includes IEEE recognized conferences such as WCNC, PIMRC, VTC, ICC, Globecom, Infocom, and journals such as IEEE Transactions on Wireless Communications, IEEE Transactions on Communications, IEEE Transactions on Vehicular Technology, IEEE Transactions on Mobile Computing, Wireless Networks
  2. Organize two 1-day workshops at the end of year and year 2 to share the results with the wireless research and industry and government agencies. This will be part of our project continuation plan in which concerted commercialization efforts will seek partnerships and collaborations.
  3. Setup a dedicated WiKi storing and providing access to all reports, publications, presentations, and other materials produced through this project.

Tasks

This work package is divided into the following tasks:

  1. Provision of periodic progress reports.
  2. Submission of technical papers and later presentation in international conferences.
  3. Submission of proposals to 3GPP LTE-Advanced Study Groups.
  4. Setup and maintenance of project WiKi.
  5. Organizing two dissemination workshops.
