1. An apparatus of a base station operable to perform downlink (DL) transmissions using a Long Term Evolution (LTE) control region of a subframe for enhanced machine type communication (eMTC), the apparatus comprising:
one or more processors configured to:
encode, at the base station, a system information block type 1 bandwidth reduced (SIB1-BR) for transmission to a bandwidth reduced low complexity or coverage enhancement (BL/CE) user equipment (UE), wherein the SIB1-BR includes an indication that the LTE control region in the subframe includes information for at least one of a machine type communication (MTC) physical downlink control channel (MPDCCH) transmission or a physical downlink shared channel (PDSCH) transmission, and wherein any consecutive N symbols from a last 14-N symbols of the subframe are copied to the LTE control region in the subframe, when the MPDCCH transmission or the PDSCH transmission is a common transmission and use of the LTE control region for at least one of the MPDCCH transmission or the PDSCH transmission is enabled; and
encode, at the base station, at least one of the MPDCCH transmission or the PDSCH transmission for delivery in a downlink over the LTE control region in the subframe to the BL/CE UE; and
a memory interface configured to retrieve from a memory the indication to be included in the SIB1-BR.
