IEEE 802.16 Session #31 Report

IEEE 802.16 Logo

Session #31 of the IEEE 802.16 Working Group on Broadband Wireless Access took place on 17-20 May in Shenzhen, China. It was the first meeting of any IEEE 802 Working Group in China. The attendance of 228 people broke the 802.16 record of 221 set at Session #30. 106 of the attendees were newcomers; many attended a Monday morning tutorial on the "IEEE 802.16 Working Group Process, Status, and Technology" (see Part A and Part B).

The session was hosted by Rajesh Bhalla of corporate host ZTE Corporation. As noted in a followup letter to the host, the arrangements, including the Wednesday evening banquet, were superb. The host also provided a company facility tour on Friday morning following the session.

Balloting Completed on Final Draft Revision of IEEE Standard 802.16
Balloting concluded on Draft 5, the final draft of IEEE P802.16-REVd, a comprehensive revision of IEEE Standard 802.16 ("Air Interface for Fixed Broadband Wireless Access Systems") and its two amendments. The draft has been submitted to IEEE's Review Committee (RevCom) for consideration at its meeting of 23 June. After approval by the IEEE-SA Standards Board, anticipated on 24 June, the document will be published as IEEE Standard 802.16-2004 and will replace IEEE Standards 802.16-2001, 802.16c-2002, and 802.16a-2003.

Comment Resolution on Mobile WirelessMAN (P802.16e) Draft
Comments were resolved following the first recirculation of the Working Group Letter Ballot regarding the IEEE P802.16e draft, which will enhance the WirelessMAN air interface to support mobile as well as fixed users. This activity led Task Group e to the development of Draft 3 for a second recirculation. The Task Group appointed ad hoc committees to address two topics - Handoff and Security - and tasked them to consolidate relevant issues raised during the session for submission during the ballot recirculation. The Task Group drafted a modification of the 802.16e Project Authorization Request (PAR) to address some obsolete language and allow for more flexibility. The modified PAR, which anticipates completion of the draft by the end of 2004, was forwarded by the Working Group for IEEE 802 EC consideration during Session #32. The Task Group issued a closing report and minutes.

Publication of Third Conformance Standard
IEEE Standard 802.16/Conformance03 ("Standard for Conformance to IEEE Standard 802.16 - Part 3: Radio Conformance Tests (RCT) for 10-66 GHz WirelessMAN-SC Air Interface") was approved as an IEEE Standard by the IEEE-SA Standards Board on 12 May 2004. This is the IEEE 802.16 Working Group's eighth standard. Publication is expected in July.

No input was received concerning the recently-approved PAR to draft the fourth document in the series, P802.16/Conformance04 (PICS Proforma for frequencies below 11 GHz). Therefore, a new Call for Contributions was issued.

Network Management Study Group Drafts two PARs
The IEEE 802.16 Network Management Study Group met and drafted two PARs, one to develop a Management Information Base for fixed service and another to develop Management Plane Procedures and Services to include both fixed and mobile service. Both were submitted by the Working Group for IEEE 802 consideration during Session #32. The Study Group issued a report and minutes.

Working Group Ad Hoc Commitee on Licensed-Exempt Coexistence
The Working Group's Ad Hoc Commitee on Licensed-Exempt Coexistence met in its efffort to provide the Working Group with recommendations regarding the advisibility of initiating standardization in this area. It issued an activity report and minutes and will meet again during Session #32.

Working Group Liaison Activities

The Session #31 document list includes references to over 150 session documents.

Minutes and Motions
The Working Group minutes are available as IEEE 802.16-04/29.
