Abstract:

During past years, architectures for cellular radio networks like 3GPP LTE evolved towards flatter topologies with less centralized nodes, shifting more and more radio-related processing towards the Base-Station or even further into so-called Remote Radio Heads near the antennas. With the emerging IP-based community services as driver for current and future traffic growth, user traffic lost its predictability, which resulted in the need for over-dimensioning of processing and forwarding resources in the radio path. This is especially true for upcoming pico and femto cell configurations in heterogeneous cellular layouts. To overcome this cost-driving effect, we are developing a concept of a Cloud Base Station as a candidate for a Light Radio (TM) (with System on Chip) evolution and General Purpose Processor configurations, which uses virtualization techniques such as dynamic and elastic allocation of base-band processing resources between small and large cell sites, as well as load balancing or load concentration between temporarily overloaded sites and their less utilized neighbors. The Cloud Base Station in a Virtualized RAN eases a smooth standards migration towards LTE-Advanced with the same deployed equipment, and in future, more and more transformation of dedicated baseband hardware onto general purpose processing platforms. With a poster session at the Bell Labs Open Day, we discuss the tight networking requirements of a Cloud Base Station in a virtual RAN, its architecture challenges and our cloud management solutions. Moreover we show research results on the concept validation based on simulations and study business-case related implications.

Biography:

Bernd Haberland studied Information Technology and Digital Signal Processing at University of Erlangen-Nürnberg. Since 1984 he is working within Alcatel (since 2006 Alcatel-Lucent). Up to 1999 he worked in the development area of Mobile Communications, where he had several accomplishments also in leadership functions as follows: Early GSM valdidation system Testmobile system GSM Base Stations for the baseband, transceiver and amplifier parts UMTS validation system

From 1999 on he was moving to research (since 2007 Bell Labs) in a leadership position, where he is still working today with the following accomplishments with his team:

  • Major contributions to Baseband Receiver Algorithms, Design Specifications and implementation for UMTS and HSPA.
  • chairman of an Alcatel Node B V2 specification task force
  • new concepts for HSPA and Smart Antennas
  • prototype for a UMTS transmitter including Power Amplifier Linearization and RF part
  • software defined radio technologies
  • ALUs  first LTE demonstrator which was exhibited at the 3GSM 2008.
  • cognitive and self-configuration radio, which enables next generation plug-and play base-stations.
  • Power Amplifier evolutions with Envelope Tracking and class O amplifier
  • Very important accomplishments are for LTE advanced  on the area of MIMO, Network MIMO and Interference Management.
  • Self-organizing networks to reduce the OPEX of operators
  • current work:  Mobile Cloud concepts and technologies

In all these areas he contributed to patents and publications. He was awarded as Alcatel Fellow 2004 and as Bell Labs Fellow 2010.
