LTE Vs NR[EN-DC] Coverage and throughput observation with 8x8 ,32x32 & 64x64 Scenario

By -

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 give 5G/NR services by deploying EN-DC 

EN-DC has major advantage that with EN-DC 5G/NR matches 4G footprint . As in 3.5GHz high losses are there so definately it will not match 4G footprint in current running 4G bands , so technolgy is to use 4G Spectrum  for UL and 5G Spectrum for DL .

EN-DC in india can be deployed with LTE- B1 , B3 , B5, B8  and NR-N78.

As per global deployement scenario EN-DC deployement with B3 & N78 gives better result 

I want to share you some  result of different MIMO and its coverage footprint w.r.t LTE [ B1/B3] in EN-DC Scenario with N78 as NR

RSRP4G vs RSRP5G in same clutter with Different MIMO


Readers above image shows how RSRP of NR and RSRP of LTE varies along with that you can identify which type of MIMO you should deploy in your network in Indian Scenario . Let me tell you above plot is not prediction its actual deployement scenario of one of operator in urban scennario .

You can identify coverage pattern for diffent MIMO and how its behaving w.r.t LTE coverage.

some of you wandring that how 64x64 not giving better result although it will have throughput advantage , my answer is definately you will have throughput advantage but how much advantage with how much cost and its very improtant 

RSRP5G vs 5G Throughput[Mbps] in same clutter with different MIMO


Above snap will end all speculation of lab testing theories and actual scenario , Gyus i will reco. to go with 8x8 or 32x32 istead of 64x64 in indian market scenario .

Downlink signals are  made up of many different components. For example, Reference Signal, PDCCH, PDSCH etc. The RS power and the SCH powers are key RF optimization parameters that influences the cell coverage. It is set according to the cell size. The higher the setting, the larger the cell coverage  on the downlink, but leaves smaller power headroom available for other downlink signals  and channels. The relation between RS power and power on PDSCH symbols (includes type A and type B symbols), has to be defined and reported to the UE, in order for the UE to demodulate 16QAM and 64QAM.1 PDSCH type A symbols has only PDSCH RE’s, PDSCH type B symbols has mixed RS and PDSCH REs. Parameter PA sets the power of PDSCH type A RE relative to cell‐specific RS, PB sets the power relation between PDSCH type B RE, and PDSCH type A RE (ρB/ρA in 3GPP). The ratio of PDSCH EPRE to cell‐specific RS EPRE among PDSCH REs for each OFDM  symbol is denoted by either ρA or ρB a...

LTE Layer management Strategy and basic working [LMS] Unlock

LMS Insight Layer Management Parameter Optimization is important aspect & it is triggered when all possible optimization techniques for ensuring best experience to customers is exhausted in the current layer For Example in a typical 3 Layered cellular network, we have LTE layer (with a mix of TDD(2.5GHz) and FDD(1.8GHz)), followed by WDCMA Layer (WCDMA2100) & then the GSM layer (1800 MHz Before actually working on Layer Management Parameter Optimization, we need to ensure Traffic Balancing within the layers is proper & as per recommendations to give desired customer experience Pre-requisite Actions Ensure below checks before moving to optimize the Layer Management Thresholds for a cell. Traffic balancing within layers should be optimal -  if network has 2 layers of LTE i.e. both TDD-20 MHz & FDD-5 MHz, Traffic distribution for collocated cells with TDD/FDD should be 75:25 (TDD: FDD) or better. This is applicable to networks with 2 carriers of WCDMA as well where the...
