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?
Which physical antenna to be hooked to which logical antenna port is purely dependent on the person who designs it. It can done in any way he wants. This is what i think
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. ?
Very good. Thanks for the clear information. I have seen also in other drawings, that we have: Option3, Option3a, Option3x, .. Option6, ... Option7, Option7a, Option7x. Are they necessary? whey would they use it?
I think these options were given to deploy 5G during the transition phase from LTE. Based on their requirement and existing network, operators can decide which kind of deployment option suits them well. I have seen networks mostly with Option 3 and 2.
Hi dear, check this video on ENDC ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-AtrzFkYrH1M.htmlsi=rxBifitY4KbB0pEk Let me know if this suffice your requirement
We have both the options. 4G core can be kept with 5G RAN which is Non Stand alone network. For 5G Core with 5G RAN we have Stand Alone architecture options.
I donot understand why is there a need to define Reference Point interfaces and architecture for 5G core. e.g. 3GPP has defined N11 as reference point interface between AMF and SMF. But AMF and SMF will communicate to each other via RESTful API calls defined as part of service based interface. So what does N11 exactly mean??
The Service Based architecture applies to the соntrol рlаnе section of the 5G Соге Netwoгk. The Reference Point architecture remains for the useг рlanе section of the 5G Core Netwoгk.
