Omni-directional Multiple Antenna Transmission for WUS Month Year doc.: IEEE 802.11-yy/xxxxr0 January 2018 Omni-directional Multiple Antenna Transmission for WUS Date: 2018-01-14 Authors: Dennis Sundman, Ericsson John Doe, Some Company

Month Year doc.: IEEE 802.11-yy/xxxxr0 January 2018 Abstract In doing figures for the transmitter, we realized that the case where the AP has multiple antennas must be considered The most basic multiple antenna case would be when the target is omni-directional transmissions Dennis Sundman, Ericsson John Doe, Some Company

Some alternatives Independent OFDM symbols on the different antennas Month Year doc.: IEEE 802.11-yy/xxxxr0 January 2018 Some alternatives Independent OFDM symbols on the different antennas No beamforming Requires several OFDM symbols to be designed Cyclic shift diversity The traditional ”flower” of subcarriers is less problem for OOK than OFDM Already well established Dennis Sundman, Ericsson John Doe, Some Company

Straw Poll For multiple transmit antennas, do you: Month Year doc.: IEEE 802.11-yy/xxxxr0 January 2018 Straw Poll For multiple transmit antennas, do you: Prefer to study the matter further Prefer to use the CSD similar to VHT Prefer to use independent symbols on each antenna 1/2/3: Dennis Sundman, Ericsson John Doe, Some Company
