Volte MOS and Throughput Vs Coverage in LTE

What is poorest RSRP to deliver Service in LTE Hi readers you might be come across a situation when people can ask what will minimum RSRP to deliver good voice experience and throughput  Below are DT observation of one of metro in India with dense clutter  Average SINR - 5.3 Average PRB Utlization - 58.2 % Volte MOS Vs RSRP  Volte MOS always Good (>3.5) when coverage better than -105/-106 dBm There is drastically degradation in MOS post RSRP -105dBm  LTE User Throughput  Vs RSRP  User throughput always good (>3Mbps) when RSRP better than -110dBm -85/-95dBm is best delivery of throughout at reference RSRP Post -100dBm throughput start degrading more frequently

Activate Automatic MCS Upgrade [actMcsUpgrade] for LTE throughput Improvement

Activates downlink MCS Upgrade functionality for non-GBR transmissions and specifies if the upgrades can increase the MCS index by one or two. The purpose of this function is to improve over the air spectral efficiency. Full RBG allocations (RAT0) are used for DL scheduling. This leads to spectrally inefficient allocations when a partial RBG is needed to drain a UE's buffer.  For example in a 20 MHz system if 5 PRBs are required to drain a UE's buffer, an allocation of two RBGs is required, i.e. 8 PRBs. If MCS Upgrade is enabled, an MCS upgrade will be used so that an allocation of one full RBG (4 PRBs) can be used to drain the UE's buffer. MCS upgrades are only used to reduce a 3 RBG allocation to 2 RBGs or to reduce a 2 RBG allocation to 1 RBG actMcsUpgrade[Activate MCS upgrade]    For Nokia OEM Paramter name is actMcsUpgrade which has different values as below  0: Disabled 1: SingleMcsIndexUpgradeOnly  2: SingleOrDoubleMcsIndexUpgrade Above Pre-Post snap is one of cluste

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

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
