Ultra-Low 2014 - International Workshop on Enablers for Ultra-Low End-to-End Latency in 5G Wireless Communications Systems

As the wireless communications community is starting to shape the 5th generation of mobile communications, it becomes clear that a key property of 5G will be to enable significantly reduced end-to-end latency, because
? we will see more and more applications that require ultra-low end-to-end latency, such as real-time video processing in the infrastructure in the context of augmented reality,
? we will experience new services in various application domains incl. road traffic, sports, education, health & care and manufacturing that require guaranteed maximum end-to-end latencies of a few milliseconds, such as vehicle-to-vehicle and vehicle-to-device communications for traffic safety,
? we are moving towards the era of the tactile Internet where wireless communications will be more and more used for distributed control rather than only content distribution, and finally
? a reduced latency is also an immediate consequence of ever increasing data rates per device, if the device complexity and cost is to be kept at the same order.
Effectively, 5G has to aim at an end-to-end latency of a few ms, which is at least an order of magnitude less than what we experience in today’s cellular systems such as LTE-A. Moreover, 5G will serve novel services that require guaranteed maximum latencies. Clearly, this will not only require massive changes in air interface numerology, but also latency-optimized signal processing on both the device and infrastructure side, and a potential rethinking of network infrastructure and architecture, control / user plane design, session management and protocol stack. The workshop provides a platform for technical experts from the radio, core network and application side to provide specific concepts or building blocks to significantly reduce end-to-end latency in 5G wireless communications systems, or point out particular applications and use cases that would benefit from a reduced end-to-end latency. The workshop chairs and TPC chairs solicit original, unpublished technical papers in the fields of (but not limited to):
? Air interface and signal processing concepts tailored towards latency reduction
? Advanced radio-resource management techniques for latency-critical traffic
? Novel approaches towards session management and protocol stack for latency reduction
? Network infrastructure and core network considerations for reduced latency
? Cloud-RAN concepts in the context of latency-critical applications
? Infrastructure and network architecture concepts for enabling distributed / edge computing and device-to-device communications
