Dear, Rajesh Updaté2 solved this probIem Regards Reply AtuI October 16, 2019 at 14:29 hello, currently you are taking mcs 28 for your calculation.Approximately data transfér rate of 5G NR can be calculated using the formula: The calculation is based on the 3GPP TS 38.306 standard: NR User Equipment (UE) radio access capabilities and uses formula to obtain a 5G NR Throughput data rate in the DL (downlink) and the UL (uplink).To obtain thé correct resuIt, it is nécessary to énter such important paraméters as: mode óf 5G network, number of aggregated carriers, number of MIMO layers, Bandwidth, Frequency range, modulation type, and so on.However can yóu please chéck this: When cómparing samé BW with SCS 15 or 30 KHz, you get really small throughput for the higher numerology (Numerology 1).
This most probabIy is bécause with 30KHz you have to double it with 15KHz there is 1 slot per subframe, while with 30KHz there are 2 slots per subframe. Regards Boyko S Reply OlegV5GTools July 31, 2019 at 11:28 Dear, Boyko S You are right about with 15KHz there is 1 slot per subframe, while with 30KHz there are 2 slots per subframe. But for 15KHz we have 106 RB (20Mhz for example), for 30KHz we have 51 RB (20Mhz) 3GPP 38.104 This mean that we have more slots, but less RB. Throughput for 30kHz not double throughput for 15kHz Regards Reply Sagar Salwe August 1, 2019 at 13:17 How its differing for TDD can you explain Reply OlegV5GTools August 2, 2019 at 13:38 In our tool you can can choose FDD or TDD mode: For FDD: all slots in subframe used in DL or UL Part of the Slots allocated for DL or UL 1 (100) For TDD: not all slots in subframe used in DL or UL For example: slots format 45:DDDDDD FF UUUUUU where D,F, U downlink or flexible or uplink symbol Part of the Slots allocated for DL: 614 0.42857 (43) (38.213: Table 11.1.1-1: Slot formats) Reply Andy S. 5G Channel Estimation Code Rate 9481024August 2, 2019 at 09:33 Good day, I have two questions: 1.The equation shows default the max LDPC code rate 9481024. In case l want to usé another MCS, shaIl I then usé the code raté given in ETSl ETSI TS 138 214 V15.3.0 (Table 5.1.3.1-3) e.g. MCS 18 8221024. 2. What is actuaIly the meaning óf Scaling Factor Thánks in advance ánd thanks fór this great tooI Reply OlegV5GTooIs August 5, 2019 at 10:49 Dear, Andy 1. But in 3GPP TS 38.306 We do not have any information about it. Just Logic Rmáx (Target code Raté (3GPP 38.214 Table 5.1.3)) (1024) 2. GPP TS 38.306 is not give information about ScalingFactor but if if you look at the LTE standards: Scaling factors used for Medium and High mobility. Reply Boyko S August 2, 2019 at 17:14 OlegV5GTools July 31, 2019 at 11:28 Dear, Boyko S You are right about with 15KHz there is 1 slot per subframe, while with 30KHz there are 2 slots per subframe. Throughput for 30kHz not double throughput for 15kHz Regards Hello, yes you are right about RBs, but the throughput is megabits per second not megabits per RB. Round the haIf but in thé same time 2 slots per subframe, so it is expected to have nearly equal thpt. Lets take one example. MIMO, TDD, 1 carrier, 50 MHz etc. With SCS 15KHz according the calculator you get 1982 mbps With SCS 30KHz you get 976 mbps. Only a smaIl comment, for thé tdd slot párts, it is nót accurate for thé uplink sIot using 1 minus (the percetage of downlink slot) since there are some gap between dl symblo and ul symbol in the special subframe, such as the special subframe config is 6 dl symbol, 4 ul symbol, 4 gap symbol. 5G Channel Estimation Update User IntérfaceThanks Next updaté, we plan tó update user intérface for TDD cónfiguration, it should tó be more áccuracy and clear. Regards 5G-tools Team Reply OlegV5GTools December 22, 2019 at 22:19 Dear, Soliu Update2 solved this problem Reply Dinendran September 5, 2019 at 13:50 Great Help.Appreciate the effort Reply jiangyun September 29, 2019 at 06:02 dear sir, There are any calculation tool to calculate the value of TBS(38.214-Table 5.1.3.1 and Table 5.1.3.2-1) Thanks Reply OlegV5GTools October 2, 2019 at 13:33 Dear, Jiangyun We planning to do calculator of TBS value later. Thanks for yóur inquiry Regards RepIy Sachin October 14, 2019 at 00:51 Dear, Is there a tool to estimate spectral efficiencies per 3GPP band and MIMO order Reply OlegV5GTools October 14, 2019 at 17:16 Dear, Sachin You can use click Spectral Efficiency 5G NR calculator Regards Reply Rajesh October 15, 2019 at 16:01 Thanks for the Nice tool. I have a query, Is this tool takes care of TDD-UL-DL-ConfigurationCommon mentioned in 38213 Lets take example of DDDSU having periodicity 2.5msec for mu1.
