Flexible network architecture is envisioned as one of
the properties of the next generation mobile networks, and is also
foreseen to significantly contribute to lowering latency, and addressing
Ultra-Reliable Low Latency Communications (URLLC).
In this paper, we study the flexibility in Radio Access Network
(RAN) configuration in terms of splitting the radio and baseband
functionalities between central cloud and distributed entities,
and the impact of this flexibility on delivery of URLLC. Three
different functionality splits have been implemented in cloudRAN,
and the impact of each of these splits on communication
latency and jitter is examined. We modeled traffic based on
the 3GPP traffic models and, for completeness, in addition to
URLLC, the two cases of massive machine-type communications
(mMTC) and enhanced Mobile Broadband (eMBB) models are
also implemented. Hence, thorough analyses are performed
and recommendation for split point between central cloud and
distributed radio units are discussed.
