4 Areas of Interest4 Areas of Interest
These are the basic areas where E3 partners areconcentrating on:
� Self-Organizing Network featuring future evolvement of organizing the functions for 3GPP RANs (incl. single /multiple RAN cases)
� Enhanced Terminal Autonomy with respect to radio link management in heterogeneous RAN environments (3GPP RAN as well as Wi-Fi, WiMAX or other RANs)
� Technology for Autonomous Cognitive ad-hoc Radio Systems (with opportunistic spectrum access)
� Long- and mid-term Dynamic Spectrum Assignment

What else at highest level in E3?What else at highest level in E3?
“Inherited” from E 2R
� Reconfigurable equipment as pre-condition for implementation of the new envisaged functions (RCM)
Required Enablers
� Ability for spectrum sensing and exchange of sensing results as enabling technique to make spectrum rela ted decisions
� Provision of constraints and/or policies concerning the radio resource (incl. spectrum) usage to the radios involved (Abstract data for a Cognitive Pilot Channel )

Different understanding of SON/SelfDifferent understanding of SON/Self --xx
� Self Organizing: From the wording often understood as a kind of autonomous management in a system (pattern: Observe –Decide – Reconfigure)Self Organizing Network: Narrow the system scope to a n etwork���� Self-x is part of almost all functional building bl ocks!
� SON is the title for a number of activities in 3GPP, NGM N, IEEE 802.16, internal T- Mobile project, …Thus, there is strong interest to dedicate a functiona l buildingblock to the corresponding identified functions in op erated RANs – this should be reflected in the functional arch itecture overview

Capabilities and use of CCRCapabilities and use of CCR
� Types of communication on CCR⇒ Broadcast to neighbors over a limited number of hops⇒ Acknowledged packet transmission to a one-hop neighbor⇒ Transmission over multiple hops to an individual destination
• Routing needed• In mobile environment finding and keeping up routes
consumes a lot of resources
� Use of CCR1. Finding own network2. Getting regulatory policy information3. Sharing spectrum sensing results and TX/RX parameters4. Negotiation about spectrum use between networks
ICT MobileSummit 2009 – Pre-Workshops Slide 13
Fitting CCR in the complete pictureFitting CCR in the complete picture
� CCR is an enabler for the new type of Autonomic Cognitive Mesh Network
� CCR provides (among other things) constraints and/or policies concerning the spectrum usage in the band(s)/sub-band(s) admitted for the Cognitive System. This is a kind of ‘restricted’CPC. It also re-distributes the information from the centralized CPC (how and where this information is received from outside the CS is not in the scope – it must only be ensured)
