1. A method for normalizing Log-Likelihood Ratios (LLRs) for bits of a transport block, the method comprising:
receiving, by a User Equipment (UE), the transport block over a channel of a wireless network;
selecting, by the UE, a normalization factor q based, at least in part, on a narrowband channel estimation being used; and
scaling, by the UE, an input LLRin for individual bits of the transport block to respectively form an output LLRout for the individual bits of the transport block by multiplying a corresponding input LLRin for the individual bits by 2q.
