An apparatus of an eNodeB operable to apply scrambling to coded bits transported via a physical downlink shared channel, PDSCH, to a user equipment, UE, the eNodeB comprising one or more processors configured to: generate, at the eNodeB, a code word that comprises coded bits for transmission to the UE, wherein the UE is a bandwidth-reduced low complexity, BL, UE or a coverage enhancement, CE, UE; identify, at the eNodeB for the BL UE or the CE UE, a scrambling sequence to be applied to the coded bits, wherein the scrambling sequence is initialized using a defined initialization value, Cinit; apply, at the eNodeB, the scrambling sequence with the defined initialization value to the coded bits to obtain scrambled coded bits, wherein the scrambling sequence is applied per subframe to the PDSCH for a given block of N acc subframes, wherein N acc represents a number of subframes in the given block; and encode, at the eNodeB, the scrambled coded bits for transmission to the UE via the PDSCH, characterized in that: when the scrambled coded bits to be transmitted via the PDSCH form a system information block type 1, SIB1, bandwidth reduced, BR: N acc is set to 1; but when the scrambled coded bits to be transmitted via the PDSCH form either: a type of system information, SI, message other than a system information block type 1, SIB1, bandwidth reduced, BR; or a paging message: N acc is set to 4 for a frame structure type 1, or N acc is set to 10 for a frame structure type 2. generate, at the eNodeB, a code word that comprises coded bits for transmission to the UE, wherein the UE is a bandwidth-reduced low complexity, BL, UE or a coverage enhancement, CE, UE; identify, at the eNodeB for the BL UE or the CE UE, a scrambling sequence to be applied to the coded bits, wherein the scrambling sequence is initialized using a defined initialization value, Cinit; apply, at the eNodeB, the scrambling sequence with the defined initialization value to the coded bits to obtain scrambled coded bits, wherein the scrambling sequence is applied per subframe to the PDSCH for a given block of N acc subframes, wherein N acc represents a number of subframes in the given block; and encode, at the eNodeB, the scrambled coded bits for transmission to the UE via the PDSCH, characterized in that: when the scrambled coded bits to be transmitted via the PDSCH form a system information block type 1, SIB1, bandwidth reduced, BR: N acc is set to 1; but when the scrambled coded bits to be transmitted via the PDSCH form either: a type of system information, SI, message other than a system information block type 1, SIB1, bandwidth reduced, BR; or a paging message: N acc is set to 4 for a frame structure type 1, or N acc is set to 10 for a frame structure type 2. when the scrambled coded bits to be transmitted via the PDSCH form a system information block type 1, SIB1, bandwidth reduced, BR: N acc is set to 1; but when the scrambled coded bits to be transmitted via the PDSCH form either: a type of system information, SI, message other than a system information block type 1, SIB1, bandwidth reduced, BR; or a paging message: N acc is set to 4 for a frame structure type 1, or N acc is set to 10 for a frame structure type 2. N acc is set to 4 for a frame structure type 1, or N acc is set to 10 for a frame structure type 2.
