On-going Activities

• The main 802.22 working group (WG) has been conducting parallel activities in four areas:

– Physical Layer (PHY)– Medium Access Control Layer (MAC)– Spectrum Sensing– Geolocation/Database

• In addition, two other task groups (TG) under 802.22 have been formed:

– IEEE 802.22.1• In the process of creating a standard which specifies methods to

provide enhanced protection to low power devices such as those licensed as secondary under FCC Part 74 in the USA (e.g., wireless microphones)

– IEEE 802.22.2• In the process of developing recommended practices for installation

and deployment of IEEE 802.22 systems

IEEE 802.22 Status as of November 2006

• Now: Draft standard version 0.1 is out

• January 2007: Expected to release draft version 0.2

• March 2007: Go to WG ballot

• July 2007: Go to Sponsor ballot– Point where Draft 1.0 is expected to be available

• January 2008: IEEE 802.22 standard approved by the IEEE Standards Association

IEEE J-SAC SI

• Guest Edited by:– Carlos Cordeiro, Philips Research North America– Babak Danenshrad, UCLA– Joseph Evans, University of Kansas– Narayan Mandayam, WINLAB at Rutgers University– Preston Marshall, DARPA/ATO– Sai Shankar, Qualcomm

• Timeline:– Submission: February 2006– Acceptance: August/September 2006– Publication: April 2007

• CFP website: http://www.argreenhouse.com/society/J-SAC/Calls/cognitive_radios.html

CONFIDENTIAL 11Philips Research North America, C. Cordeiro

IEEE J-SAC SI

• A large number of quality papers were received in response to the CFP

• Each paper received at least 3 reviews and was personally looked at by at least one of the Editors

• Papers were selected based on:– Appropriateness and relevance for the SI– Comprehensive and well rounded treatment of the many different

and interesting topics in this emerging area

• In the end, 11 papers have been accepted covering a variety of very important topics:

– Fundamental performance aspects, spectrum sensing, detection and estimation approaches to spectrum sharing, MAC design, competitive spectrum sharing and resource allocation, and etc.

IEEE DySPAN 2007 Tutorials

• Together with John Chapin (Vanu, Inc.), I am co-chairing the technical tutorial activities of DySPAN 2007

• The official deadline for technical tutorial proposal submission was November 15, 2006

• However, we may consider additional proposals provided they are submitted by November 30, 2006

• Please contact the technical tutorial co-chairs at jchapin@vanu.com and Carlos.Cordeiro@philips.com if you have questions
