Are the 5G toolbox functions coder friendly? I am getting errors while generating C++ code for some 5G toolbox functions. (v2019a)

In some functions, the array sizes are dynamically changing which is not supported by coder. This gives errors in coder.
Some functions require inputs to be of bigger bitwidth (uint8 or double) where logical would also have sufficed. These datatypes are validated at the inputs. In order to make coder pass, we are giving bigger datatypes. Is there a way to get around this?

Looking at the list of functions in 5G Toolbox in release R2019a, I see that 67 of them are listed as having the "C/C++ Code Generation" extended capability. Are the functions you're trying to use listed when you filter based on that extended capability? If so, open the function's reference page and scroll down to the "Extended Capabilities" section at the end and see what usage notes or limitations are listed there.
Note that you can do this same listing and filtering in other products, such as in the list of functions in MATLAB.

Hi Pranjali,
Regarding the dynamic array sizes, can you state the specific functions that you are referring to, and, if appropriate, the usage which requires them to be dynamic. For code generation troubleshooting, we really need to know the details.
Regarding the data types, a C99 boolean is at least a char and on most platform will probably map to the same size as an unit8. So, a logical will not be 'bigger', without resorting to bitpacking representations etc.
