Abstract

See full text

Technology for an eNodeB operable to apply scrambling to coded bits transported via a physical downlink shared channel (PDSCH) to a user equipment (UE) is disclosed. The eNodeB can generate a code word that comprises coded bits for transmission to the UE. The UE can be a bandwidth-reduced low complexity (BL) UE or a coverage enhancement (CE) UE. The eNodeB can identify, for the BL UE or the CE UE, a scrambling sequence to be applied to the coded bits. The scrambling sequence can be initialized using a defined initialization value (cinit). The eNodeB can apply the scrambling sequence with the defined initialization value to the coded bits to obtain scrambled coded bits. The eNodeB can encode the scrambled coded bits for transmission to the UE via the PDSCH.
