1. A method of wireless communication performed by an enhanced machine-type communications (eMTC) user equipment (UE), comprising:
receiving, via a system information block (SIB) type 1 (SIB-1), an indicator comprising a one-bit flag configured to indicate whether use of a control region of a Long Term Evolution (LTE) physical downlink control channel (PDCCH) for a downlink transmission is enabled or disabled; and
receiving, based at least in part on a backward compatible resource element mapping that is determined based at least in part on receiving the indicator, the downlink transmission during the control region.
