1. A method for decoding a bitstream comprising encoded Higher Order Ambisonics (HOA) representations, said method comprising:
reading a bit KindOfCodedPredIds;
determining, based on a determination that KindOfCodedPredIds=0: an array ActivePred, wherein each element of the first array ActivePred indicates if, for a corresponding direction, a prediction is performed;
determining a vector ptype, wherein the vector ptype is determined based on the array ActivePred; and
determining, based on the vector ptype, a matrix PIND denoting indices from which directional signals a prediction for a direction is to be performed.
