Abstract The use cases envisioned for the future are dictating demanding and very diverse requirements for 5G mobile communication systems. State of the art systems, such as LTEA, cannot meet future network requirements in terms of data rate, latency, reliability and ability to support many devices. Further, the envisioned ultra-dense deployments bring challenges of complex network management and the provisioning of backhaul to a large number of network nodes. For the future proofness, the 5G architecture should be flexible enough to support new usages of the networks. We study these challenges and approach them mainly from the RAN architecture perspective. We provide initial concepts that will be further evaluate in the course of the project. We found, that integration of mm-wave system with systems operating below 6 GHz (e.g. LTE-A) on the lowest possible level of the network architecture could solve most of identified problems. While the proposed initial solutions outline the direction for further development of the 5G architecture, many questions are still open and require further study.

Executive summary This document discusses a range of architectural aspects that are critical for the integration of mm-wave technology, and specifically mm-wave Radio Access Technology (RAT), in 5G mobile networks. While radio spectrum above 6 GHz offers contiguous high bandwidth resources for high capacity radio links, it also gives rise to new challenges in terms of user mobility and interference due to the harshness of the radio environment and the use of highly directional links. These are important considerations for the design of efficient network architectures at these frequencies. The document first gives a brief overview of the main mm-wave related use cases and related deployments and requirements. Then it outlines the requirements and initial concepts envisioned for 5G mm-wave architecture in 6–100 GHz frequency band, and discuss some crucial aspects of its integration within the 5G networks. The proposed concepts include: • Network slicing to address needs of 5G use cases with highly divergent requirements. By operating on logical instead of physical elements network slicing provides architecture flexibility and future proofness. • Multi-connectivity with multiple mm-wave base stations and as a way to integrate multiple RATs. Multi-connectivity between mm-wave and
