Joerg:
Rejected - For: 3, Against: 6
Recommendation:
TGm adopt 908r3

3. DL MIMO open issues SCW vs. MCW OL SU-MIMO
Recommendation: Keep the current SDD text on SCW vs. MCW description
Comments to be superseded: 396, 397, 398
OL SU-MIMO
Recommend TGm to accept comment 418
Recommend to remove STBC
No STBC – For: 18 Against: 3
No SFBC – For: 0
SFBC/STBC – For : 8, Against: 15
Comments to be superseded: 406, 407, 423.
Recommend TGm adopt contribution 1230, which includes the following changes:
Update page 69, line as follows: “For OL SU-MIMO, the following schemes are FFS: 4Tx rate-1 SFBC + Antenna hopping, 4Tx rate-2 Double SFBC + Antenna hopping, 4Tx rate-2 SM + Antenna hopping, 4Tx rate-3 SM + Antenna hopping, 4Tx rate-3 hybrid SM + SFBC + Antenna hopping”.
Remove the D(k) matrix from page 69, line 2, Equation 4 and updated the text in section accordingly.
Comments superseded: 415
Recommend TGm to supersede the following comments by MIMO RG recommendation
403, 408, 409, 410, 411, 412, 413, 416, 417, 418, 420, 421, 422.

4. DL MIMO open issues Codebook Feedback mechanisms
Recommend TGm to adopt 1205
Comments to be superseded:
428, 429, 430, 433, 435, 436, 451, 603
Recommend TGm to adopt 947r4
434, 441, 442, 443, 444, 453, 460, 462, 463
Feedback mechanisms
Recommend TGm to continue discussion on feedback mechanisms, taking into account actual uplink feedback impairments
Commentors would like to self-reject 466, 467, 468 at this point in time because more discussion is needed
