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.
