OEM Vendor Perspectives

How can the network core be simplified? – Can NFV and SDN principles be leveraged to provide more flexible functions and capabilities?

It is expected that 5G use cases will demand very diverse and sometimes extreme requirements. Can a single solution satisfy all the extreme requirements at the same time avoiding over-specification and unacceptable cost?

Considering the need for several use cases to be active concurrently in the same operator network, how can a 5G system deliver a consistent user experience over time for a given service everywhere the service is offered?

How widespread can data rates up to 1 Gb/s be supported and in which environments?

Considering a requirement for at least 50 Mb/s to be available everywhere at a reasonable cost, what are the building blocks to achieve this?

Can E2E latency of 1 ms be achieved for the use cases which require extremely low latency?

Considering Network Management (automation, self-configuration, self-healing)

How is backwards compatibility and not rip and replace achieved for 5G?

Given the wide spectrum of capabilities that need to be delivered, will 5G be comprised of more than one RAT, each optimized for certain use cases and/ or spectrum, hence comprising a “5G RAT family”?

Is a new RAT motivated by higher carrier frequencies (e.g., bands above 6GHz), lower latency, and specific use cases essential?

How can the number of RATs be minimized, ideally down to one?

If multiple RATs are to be introduced, how can commonality be achieved to the largest extent?

Exploring options to interface the access technologies - Advantages and disadvantages. Should all 5G components of the 5G RAT family be supported by new 5G functions (5GFs) design, while other RATs (e.g., Wi-Fi) and the fixed network are also supported through the new 5GFs design?

Should LTE/ LTE-Advanced and Wi-Fi, as well as their evolution, be supported by the new 5G network design, thus, the access-agnostic network functions accommodates any new RATs, as well as LTE/ LTE-Advanced, Wi-Fi, and their evolution
