Determining Transport Block Size in Communication Networks

Abstract

A user device (UE) is provided, comprising one or more non-temporary computer-readable media storing one or more computer-executable instructions for determining the transport block size for a physical uplink shared channel (PUSCH) transmission, and at least one processor coupled to one or more non-temporary computer-readable media. The processor is configured to execute one or more computer-executable instructions to cause the UE to determine whether orthogonal cover code (OCC) is applied to the PUSCH transmission, if OCC is applied to the PUSCH transmission, to determine the diffusion coefficient of the OCC, and if OCC is applied to the PUSCH transmission, to determine the transport block size using a scaling coefficient determined based on the diffusion coefficient.
