Split Options for 5G Radio Access Networks

  • 1. Deutsche Telekom AG


5G networks are supposed to offer a high flexibility in a several ways. In this regard, a twofold split of the processing in the radio access network is under discussion: A control plane / user plane split to support the software defined network-ing principle and a radio protocol stack layer based split to allow a flexible placement of processing functions between a central and one or more distributed units. In this work, the motivation and state of the art for both splits are described including a discussion of the advantages and disadvantages. It is followed by a description of a network architecture al-lowing a flexible implementation of these splits. This especially focuses on the required interfaces between control and user plane.
