1. A method for transport block size (TBS) determination performed by a wireless device, the method comprising:
receiving a first control message for assigning a Physical Downlink Shared Channel (PDSCH), the first control message indicating a first Modulation and Coding Scheme (MCS);
determining, when the first control message comprises a Cyclic Redundancy Check (CRC) scrambled by a first type of Radio Network Temporary Identifier (RNTI) and when the first control message further indicates a scaling factor value of 0.5 or 0.25, a first TBS by scaling a first intermediate number of information bits (Ninfo) using the scaling factor value, the first intermediate number of information bits determined based at least on the first MCS, and wherein the first intermediate number of information bits is determined using the formula Ninfo=NRE·R·Qm·υ, where NRE=number of resource elements, R=code rate, Qm=modulation order, υ=number of layers.
