LOLA Project Structure

Project strategy and workpackage description and LOLA pert diagram is presented.

Project Strategy: The LOLA proposal aims to design and validate access-layer radio technologies on three integrated system testbeds covering the two network topologies and the two low-latency application scenarios. Studies will be carried out during the first phase (first nine months) to define the targets of the core workpackages and validation scenarios, their interfaces and their specifications. Subsequently, solutions that meet the determined requirements will be identified; making use of existing technological building blocks available to the LOLA partners. Finally, the implementation and integration issues will be dealt with in order to convincingly validate the proposed technological innovations.

Workpackage Description: The project is built around the following technical work-packages with a top-down approach from system overview to technological prototypes:

  • WP2 covers all system engineering aspects of the two network topologies under consideration (cellular and mesh). After defining precisely the target application scenarios to address in the project, WP2 provides system architecture and requirements for WP3 and WP4, as well as technical specifications for the three testbeds implemented in WP5. WP2 is therefore the starting point of the project allowing for a consistent approach toward common objectives, system requirements and working assumptions. It is the role of the industrial partners to lead this WP in order to guarantee a solid industrial vision regarding the application scenarios and requirements. WP3 covers the study of the traffic characteristics of M2M and gaming applications and derives models of the latter based on real-time measurements.
  • WP3 involves measurement and modelling of traffic patterns with regard to low-latency aspects. The outputs of WP3 are traffic models integrated into the traffic generation modules used for system performance evaluation on Testbed 1 in WP5.
  • WP4 covers the study PHY/MAC algorithms (AMC, traffic scheduling, HARQ) and mechanisms in accordance with WP2 requirements. In addition selected implementations will be carried out on existing real-time platforms used in WP5 for Testbeds 2 and 3 and PHY abstraction models will be developed for Testbed 1.
  • WP5 covers the integration of selected WP3 and WP4 technologies on three different testbeds satisfying WP2 requirements. A small-scale field trial (Testbed 3) of selected technologies will be carried out at the end of WP5.
  • WP6 deals with dissemination and standardization issues, which are critical in order to promote the innovations of the consortium.
