Task Group m (TGm): Advanced Air Interface
Task Group m (TGm) continued with its advance work in the development of the P802.16m project to amend the IEEE 802.16 WirelessMAN-OFDMA specification so that, while offering continuing support for legacy WirelessMAN-OFDMA equipment, it can meet the emerging cellular layer requirements of IMT-Advanced next generation mobile networks. Following comment resolution, a new version IEEE 802.16m-08/003r3 of the System Description Document (SDD) was issued, and a new version IEEE 802.16m-08/004r2 of the Evaluation Methodology Document (EMD) will follow. Five new Rapporteur Groups (on HARQ, Preamble, Downlink MIMO, Uplink Control, and Uplink PHY) were chartered until Session #56, along with a Relay Ad Hoc group. The TG issued a closing report and minutes.

Update: A Call for Comments and Contributions on Project 802.16m System Description Document (SDD) opened, through 7 July.

Relay Task Group
The Relay Task Group completed the resolution of comments received in WG Letter Ballot Recirculation #28c. The Working Group agreed to issue a new draft, P802.16j/D5, and initiate Recirc #28d through 21 June. A closing report and minutes were issued.

Maintenance Task Group
The Working Group's Maintenance Task Group is developing the 802.16Rev2 project to revise IEEE Std 802.16. It resolved comments received in WG Letter Ballot Recirculation #26c.

Liaison Activities
The WG's ITU-R Liaison Group met actively throughout the session, issuing a meeting report (L802.16-08/035). As the result of this activity, the following WG actions arose:

The WG issued a Liaison Statement to the WiMAX Forum (L802.16-08/034) regarding the Forum's liaison statement (L802.16-08/024) on the update of Recommendation ITU-R M.1457.
The WG issued a Liaison Statement to the WiMAX Forum regarding a statement from ITU-R Working Party 5D on Adjacent Channel Selectivity (L802.16-08/031). This continued earlier correspondence and followed a Liaison Statement from the WiMAX Forum (L802.16-08/026).
The WG approved comments in regarding to a consultation on Draft ECC Report 120. The revised document (L802.16-08/030r2) was submitted to the ECC by the IEEE 802.18 Radio Regulatory TAG.
The WG agreed to comments (L802.16-08/033) to the FCC regarding a Public Notice on the 2360-2400 MHz band. However, the 802.18 TAG declined to submit these.
The WG agreed to a draft contribution to ITU-R Working Party 5D on IMT-Advanced evaluation guidelines (L802.16-08/032). However, the 802.18 TAG declined to pursue approval of this document.

Following the session, the WG received a statement from the 802.11 and 802.15 WGs on Co-located Coexistence (L802.16-08/036), as a response to an inquiry raised by the 802.16 WG in March (L802.16-08/019). As a result, the 802.19 Coexistence TAG has instituted an email reflector on the topic. Discussion has begun <http://ieee802.org/19/arc/stds-802-19colocate> and a meeting is planned for the July 802 Plenary.

About IEEE 802.16
The IEEE 802.16 Working Group on Broadband Wireless Access Standards has developed and is enhancing the WirelessMAN® Standard for wireless metropolitan area networks.

"802.16 News" Mailing List
The "802.16 News" mailing list ("stds-802-16-news") has the sole purpose of distributing major announcements related to the Working Group. Those interested in following the progress of the group but not in the day-to-day details may wish to subscribe. Only the Working Group Chair is eligible to post to the list, and mailings will be rare: once after each bimonthly session and additionally for major news, such as the approval of a new standard. Those subscribing to the stds-802-16 mailing list, for active Working Group participants, need not subscribe to stds-802-16-news since the postings will be redundant.

With the approval of the IEEE 802.16 Working Group, this report (20 June 2008 release) was drafted and edited by:

Roger Marks (r.b.marks@ieee.org)
Chair, IEEE 802.16 Working Group on Broadband Wireless Access Standards
