The four main achievements of SPEED-5G so far
Having reached two thirds of its lifetime, the SPEED-5G project would like to share with the research community some significant achievements that can contribute to the progress of 5G technologies beyond the state of the art.
eDSA definition: A detailed definition of the newly introduced extended Dynamic Spectrum Access has been developed by the project consortium, including the impact on different protocol stack layers, the definition of specific building blocks at the MAC and the RRM layers and the enhanced 5G Cloud Edge architecture.
SPEED-5G Protocol Stack: SPEED-5G has developed a proposal for a 5G protocol stack natively integrating the eDSA paradigm. In the access part, the RRM and the MAC layers have been extended, defining the main building blocks of each layer and the basic system operation for a licensed-like operation approach, with non-contention based access, and unlicensed-like operation with contention based access. This protocol stack has defined a harmonization point in order to integrate legacy RATs and new 5G enhanced air interface variants.
SPEED-5G Enhanced Architecture: A detailed definition of the SPEED-5G Cloud Edge architecture has been developed by the project consortium, defining the needed building blocks for supporting the eDSA function across the entire network in order to operate using licensed, unlicensed and lightly-licensed spectrum, providing the interfaces to a centralised LSA (Licensed Shared Access) controller.
FBMC-enabled MAC in support of xMBB and mMTC: A new MAC layer has been defined for a well-known 5G waveform candidate, i.e. Filter Bank Multi-Carrier (FBMC), which supports the two main 5G use cases, mobile broadband and massive IOT. The FBMC-enabled MAC proposes different numerologies in order to adapt the waveform to the specific needs of each use case, and it does so by analysing the traffic patterns and the expected performance of each configuration for the target application.
Next steps: In the last third of the project, SPEED-5G will work on the final definition of the RRM solution options and recommendations, which will be provided in deliverable D4.3. The report will contain a conclusive evaluation of the proposed solutions and the associated architecture for access and fronthaul/ backhaul resource management. In addition, it will provide general guidelines for enhancing resource management functionalities in future 5G network design.
SPEED-5G also works on real-time protocol implementation in work package 5. The final deliverable, D5.3, will describe the implementation architecture of the protocol implementation. This includes a description of the HW/SW partition and the mapping onto the HW platform; the primitives that are implemented will be described as well.
Finally, the testbed deployment and trials in work package 6 are intended to validate the innovative solutions developed in SPEED-5G and assess their effectiveness and performance in terms of the predefined key performance indicators through trials via a testbed deployment (final deliverable: D6.3).
