May 2016 802.11-16/0637r0 Load balancing for MU-MIMO over 484/996-tone RU For MU-MIMO+OFDMA, the MU-MIMO STAs information on 484/996-tone RU is distributed on CH1 and CH2 the user block subfields of MU-MIMO are split over 2 HE-SIG-B channels for 484/996-tone RU . If all user block subfields are signaled in one HE-SIG-B channel, there is no user to signal in the other HE-SIG-B channel. Hence, The entry of Zero STA is needed as a special case of load balancing for MU-MIMO on 484/996-tone RU HE-SIG-B common HE-SIG-B dedicated STF/LTF/Data 8-bit for CH1 (5 STAs) 8-bit for CH3 (2 STAs) 8-bit for CH2 (0 STA) 8-bit for CH4 (7 STAs) 8-bit for CH1 (5 STAs) 8-bit for CH3 (2 STAs) 8-bit for CH2 (0 STA) 8-bit for CH4 (7 STAs) 1 #1, 2, 3,4,5,6,7 (5) (0) CH1 OFDMA on 80MHz MU-MIMO of STA#1, 2, 3, 4, 5 2 CH2 #8,9,10,11,12,13,14 1 (2) #1, 2, 3,4,5,6,7 STA#6,7 CH3 2 CH4 #8,9,10,11,12,13,14 STA#8,9,10,11,12,13,14 (7) Submission Slide 13 Ming Gan et al.

Opt1: use only one entry to indicate Zero STA state without indicating RU size Opt2: use two entries to indicate Zero STA state for 484-tone RU and 996-tone RU respectively We slightly prefer Opt2 to indicate the Zero STA on specific RU size CH1 CH2 CH3 CH4 CH5+6 CH7+8 STA#1~#9 (9STAs) over 242-tone RU STA#10~#11 (2STAs) over 242-tone RU STA#12~#14 (2STAs) over 242-tone RU STA#15~#17 (3STAs) over 242-tone RU STA#18~#20 (3 MU-MIMO STAs) over 484-tone RU STA#21~#24 (4 MU-MIMO STAs) over 484-tone RU f 80MHz 80MHz f The STAs, who only successfully detect HE-SIG-B on CH1, can still know the RU allocation of 2 x 484-tone RU instead of 996-tone RU on CH5,6,7,8.
