Call for Papers The goal of 5GArch workshop is to expose latest insights from industry and academia on 5G architecture design, a quickly growing topic. Indeed, over the last couple of years different trends emerged calling for a rethinking of the current 4G architecture, which does not scale to the relentless traffic demand, signaling overhead, etc. In particular, from a technology perspective, the emergence of virtualization at the core network and (partly) at the radio access network is seen as crucial going beyond 4G networks. Also the increase in small cell base station density and the number of carrier components is set to follow its course spanning both microwave and milimeterwave spectrum. The idea of separation between data and control (a.k.a. Phantom Cell-like) and between downlink and uplink due to traffic asymmetry imbalance is gaining significant grounds. In addition, the use of distributed content caching in different parts of the network (EPC/RAN/edge) is considered as one of the most disruptive paradigms in 5G from both an architectural and edge intelligence point of view. From a service perspective, the emerging importance of new services requiring a very low latency or/and a very high reliability, coupled with the prevalence of internet of things services which cannot be enabled by today’s architecture, are crucial. All these aspects mandate a clean-slate approach to tackling the increasingly complex problems. Topics of interest include but are not limited to the following:  Architectural enablers for new services, e.g. low latency, high reliability, machine type communication  Native inclusion of small cells  Native inclusion of aggregation, with licensed and unlicensed spectrum  Native inclusion of alien systems such as Wifi  Smart content caching and content distribution  Separation between data and control  Separation between downlink and uplink, dual connectivity  Architectural enablers forD2D communications  multi-RAT/tier/carrier integration  C-RAN, SDN, NFV The workshop accepts only novel, previously unpublished papers. All submissions should be written in English with a maximum paper length of 6 printed pages (10-point font) including figures.
