Hello readers there are multiple questions about 5G/NR future in india as trials are only carried out by all major 3 operators  with help of Major 3 OEMs  Ericsson , Nokia & Samsung with restriction of 30 eNB per scenario[Urban , Rural , Semi Urban] in a PLMN  Below is some basics of measurement difference Jio is doing trails with indegenious system so they have adavantage of doing trials on 300 eNB per scenario in PLMN as per letter of Ministry of communication and they are doing trials . So one question is genuine that which 5G/NR options will be adopted by all 3 operators of india and answer is very simple and its Option3x . As still out of 3 , 2 operators are not willing to loose 2G customer and hence  there is no way of thinking of loosing 4G customer by deploying Option2 is  5G/NR SA  with additional massive investment . I will not go into details  but overview is that Option3x is future of 5G/NR in india  Option3x has advantage that with same Core, operators will be able to

4G Americas have published whitepaper titled "MIMO and Smart Antennas for Mobile Broadband Systems" . The above picture and the following is from that whitepaper Actually MIMO operation is Subset of diffirent Transmission Mode(TM) Below are some terminology used and their meaning  MIMO  :- MIMO is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas  to exploit multipath propagation ,  it is being  used in Wi-Fi , 3G (HSDPA+) , LTE , LTE-A(4G) MIMO systems are used to improve the robustness of data transmission or to increase data rates. Typically, a MIMO system(MxN) consists of m transmit antennas and n receive antennas SU-MIMO:-  It will provide multiple layers of communications to a handset for increasing of throughput. Each communication layer added to the User will increase the final throughput based on number of layers. Extra layers are been added using extra antennas in space diversity and more Transmitters in Base-st
