Reply comment resolution for comment #541 Resolution on reply comments Alexei 1222 agreed Make similar comment on DL MIMO text Jun Withdrawn Shaohua 1. Agreed. Chairs’ notes striked out 2. Accepted modified Page 4, Line 27, Delete “Packet size Page 4, line 26, Change to “MCS / Packet Size” Page 2, Change Figure 1 accordingly Hongwei Joerg: Rejected - For: 3, Against: 6 Recommendation: TGm adopt 908r3

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open issues SCW vs. MCW OL SU-MIMO Recommendation: Keep the current SDD text on SCW vs. MCW description Comments to be superseded: 396, 397, 398 OL SU-MIMO Recommend TGm to accept comment 418 Recommend to remove STBC No STBC – For: 18 Against: 3 No SFBC – For: 0 SFBC/STBC – For : 8, Against: 15 Comments to be superseded: 406, 407, 423.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 13-14 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 11.8.2.1.1. 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 Comments superseded: 415 Recommend TGm to supersede the following comments by MIMO RG recommendation 403, 408, 409, 410, 411, 412, 413, 416, 417, 418, 420, 421, 422.

DL MIMO open issues Codebook Feedback mechanisms Recommend TGm to adopt 1205 Comments to be superseded: 428, 429, 430, 433, 435, 436, 451, 603 Recommend TGm to adopt 947r4 434, 441, 442, 443, 444, 453, 460, 462, 463 Feedback mechanisms Recommend TGm to continue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
