Abstract
While drawing figures for the transmitter, we realized that the case where the AP has multiple TX antennas must be considered
The most basic multiple antenna case is omni-directional transmissions

Some alternatives
Independent OFDM symbols on the different antennas
No unintentional beamforming
Requires several OFDM symbols to be designed
Cyclic shift diversity
CSD is expected to work well with OOK
Already well established

Straw Poll
For multiple transmit antennas, for the WUR part of the signal, do you:
Prefer to study the matter further
Prefer to use the CSD 1/2: 17/1
