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

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.
