Why it is 2 \times 2 MIMO even though there are 4 physical antenna elements at gnB? (at 7:36) Again at 8:32 it is mentioned 8 cross-polarized antenna elements when the figure shows 16 of them. Does it mean all the antenna elements in a column have the same RF chain thereby transmitting the same data?

Thanks for the informative video, can you also confirm when pdsch and DMRS holds antenna port 1000 and 1001 that means NW is sending two different pdsch data from antenna ports 1000 and 1001 separately. ?

Yes this is the case of 2x2 MIMO and it is possible to use spatial multiplexing, so gNB may send two data different streams from each port.

@@TeleTale369 thank you for confirmation
