What is pusch in 5G?
In 5G NR, PUSCH is the physical uplink channel that carries user data. DM-RS and PT-RS are the reference signals associated with PUSCH. DM-RS is used for channel estimation as part of coherent demodulation of PUSCH. To compensate for the common phase error (CPE), 3GPP 5G NR introduced PT-RS.
What is MCS in 5G NR?
For any communication technology, Modulation and Coding Scheme (MCS) defines the numbers of useful bits which can carried by one symbol. In contrast with 5G or 4G, a symbol is defined as Resource Element (RE) and MCS defined as how many useful bits can be transmitted per Resource Element (RE) .
How do you calculate TB size in 5G?
Step to Calculated TBS
The total number of REs within the bandwidth of a single RB is 12 x 14 = 168 using normal cyclic prefix. The final value is multiplied by the number of allocated Resource Blocks to generate a value for .
How is MCS calculated?
In other words MCS depends on error probability. Typically there is error probability threshold defined that equal to 10%. To maintain error probability not more than this value in varying radio condition MCS is adjusted accordingly. In LTE it's done once per TTI (1 ms) individually for each active user.
