March 2008 Next Steps Correspondence groups are being established to try and reach agreement on numbers prior to the Dubai meeting. IEEE 802 will continue to participate. IEEE needs to organize more formal defense of proposals and organize attendees/presenters for the June WP5D meeting Bruce Kraemer (Marvell); Darwin Engwer(Nortel)

Develop rationale for Cell Spectral Efficiency March 2008 Task #1 Develop rationale for Cell Spectral Efficiency Bruce Kraemer (Marvell); Darwin Engwer(Nortel)

IEEE Contribution Test environment Downlink Uplink Stationary March 2008 IEEE Contribution 4.1 Cell spectral efficiency Cell[1] spectral efficiency is defined as the aggregate throughput of all users divided by the spectrum block assignment size (inclusive of PHY and MAC layer overheads). Test environment Downlink Uplink Stationary [2.6] bit/s/Hz/cell 1.3 bit/s/Hz/cell Pedestrian [1.3] bit/s/Hz/cell Vehicular [2] bit/s/Hz/cell [1] bit/s/Hz/cell High Speed [0.5] bit/s/Hz/cell Assuming the Test Environments described in the IMT.EVAL working document, Doc. 8F/1170, Attachment 6.3. [1] A cell is equivalent to a sector,.e.g. a 3-sector site has 3 cells. Bruce Kraemer (Marvell); Darwin Engwer(Nortel)
