What is the default tx mode in uplink laa and wifi sta?

[John Young]

In downlink, the txMode of both are MIMO. Since ues  and stas  both have 1 transmission antenna, but aps and enbs both have 2 reception antennas. So do they have reception diversity gain or something like that? Or in uplink, it is SISO?

[Tom Henderson]

For Wi-Fi, a 1x2 diversity gain (3 dB) is used. For LAA, I believe it
is just the default uplink configuration for LTE.
