DESCRIPTION:AP Cooperation schemes which tackle the cell-edge user problem\
 , are expected to be in the focus of Wi-Fi 8. Among them\, Coordinated Bea
 mforming (CoBF) is expected to play a key role\, mainly due to the minimal
  inter-AP synchronization and joint processing it requires. In this talk w
 e will analyze CoBF from the perspective of multi-user interference (MUI) 
 and show that the scheme currently envisioned in Wi-Fi 8 is broken! Specif
 ically\, we will show that (in contrast to DL MU-MIMO) when the number of 
 STA Rx antennas is larger than the number of streams\, the STA does not ha
 ve enough DoF to mitigate the MU interference and the scheme collapses. Af
 ter we identify this problem\, we will propose a new feedback concept whic
 h completely solves the problem\, leads to zero MUI\; while keeping the Wi
 -Fi feedback format and implying lower computational complexity! We will d
 emonstrate the ideas in this talk with a short MATLAB demo.\n\nSpeaker(s):

X-ALT-DESC:Description: <br /><p>AP Cooperation schemes which tackle the ce
 ll-edge user problem\, are expected to be in the focus of Wi-Fi 8. Among t
 hem\, Coordinated Beamforming (CoBF) is expected to play a key role\, main
 ly due to the minimal inter-AP synchronization and joint processing it req
 uires. In this talk we will analyze CoBF from the perspective of multi-use
 r interference (MUI) and show that the scheme currently envisioned in Wi-F
 i 8 is broken! Specifically\, we will show that (in contrast to DL MU-MIMO
 ) when the number of STA Rx antennas is larger than the number of streams\
 , the STA does not have enough DoF to mitigate the MU interference and the
  scheme collapses. After we identify this problem\, we will propose a new 
 feedback concept which completely solves the problem\, leads to zero MUI\;
  while keeping the Wi-Fi feedback format and implying lower computational 
 complexity! We will demonstrate the ideas in this talk with a short MATLAB
  demo.</p>
