IEEE 802.16m Project
• amendment project, initiated 2006
• “Advanced Air Interface”
– Amend IEEE 802.16 WirelessMAN-OFDMA specification toprovide an advanced air interface
– meet the cellular layer requirements of IMT-Advanced next
generation mobile networks– support for legacy WirelessMAN-OFDMA equipment (i.e.,
backward compatibility)
– provide performance improvements to support futureadvanced services and applications

• including 3GPP (W-CDMA) & 3GPP2 (cdma2000)
• M.1457 Rev 7 (2007) adds “OFDMA TDD WMAN”
– Based on IEEE Std 802.16 (including 802.16e)
– Implementation profile developed by WiMAX Forum
• M.1457 Rev 9 (2009) completed by WP 5D
– Updated reference to IEEE Std 802.16-2009
– Included FDD as well as TDD

IEEE Participation in IMT-Advanced
• Document 8F/1083 (3 January 2007):– “New IEEE Project to Develop a Standard to Meet the Cellular
Layer Requirements of IMT-Advanced”
– Notified ITU-R that 802.16m project is intended for future
contributions on IMT-Advanced
• Presented and discussed IEEE 802.16m Project during IMT-Advanced Workshops in Kyoto (May 2007) and Seoul (October2008)
• Developed and closely followed a workplan (L802.16-08/058)to meet ITU-R timeline (next slide)
• WG Chair and several members actively participated in, andcontributed to, WP 5D discussions on IMT-Advancedrequirements, evaluation methodology, and processes

Planning for inputs
• Solicited input material towards development of candidate RIT:
– Call for comments and contributions over the past year
– Correspondence Group in between IEEE 802.16 sessions
– Liaison activity with the external organizations (e.g. WiMAX Forum)
• Multi-company contributions were received containing
calibration/simulation results as well as text for descriptiontemplates and other elements of the submission
– ASB, ETRI, Fujitsu, Hitachi, Intel, KDDI, LG Electronics, Mediatek,
Mitsubishi Electric, Motorola, NEC, Samsung, Toshiba, UQ

Communication with SDOs
• Active liaison relationship, including on IMT-Advanced, with
TTA, ARIB, and the WiMAX Forum has been quite fruitful
– Contributions from Korea and Japan to WP 5D
supporting/endorsing inclusion of IEEE proposal in IMT-Advanced
– Contributions from the WiMAX Forum on content/endorsement
– MoU and agreement on next steps between IEEE and TTA/ARIB

• In Contributions #1 and #2, IEEE communicated with the ITU-R WP 5D its
intent to submit 802.16m as a candidate IMT-Advanced technology
consisting of the following elements:
– Technology description template (4.2.3.2)
– Link budget template (4.2.3.3)
– Self evaluation report including:
• Services compliance template (4.2.4.1)
• Spectrum compliance template (4.2.4.2)
• Performance compliance template (4.2.4.3)
– Indication of ITU IPR policy compliance– Version of minimum technical requirements and evaluation criteria, pointing to
Reports ITU-R M.2133, M.2134, and M.2135, as appropriate.
– Any additional material that in our view could assist with the evaluation process.
• WP 5D confirmed [5D/TEMP/206] that above content “w o u l d , i n
p r i n c i p l e , s e r v e a s a c om p l e t e s u bm i ss io n .”
