The appropriate Release Notes for R2016b says simply:
‘Replace all instances of randint with randi.’
According to this Answer, randi is simply randint with the order of the arguments changed.

That particular use of randint() is a bit unusual. It would translate to
rng(123);
sts_seq = randi([0 1], 1, length(SC_Position)/2) .* 2 - 1;
With 0 or 1 being multiplied by 2 and add 1, then the results would be either -1 or +1.

@Walter — Thank you!
I don’t have the Communications Toolbox, so I have no experience with it.
