1. A reduced-complexity wireless device configured to operate in a wireless network compliant with a New Radio (NR) radio telecommunications protocol, the reduced-complexity wireless device comprising:
one or more processors configured to:
transmit a type of the reduced-complexity wireless device to a base station communicatively coupled to the wireless device;
receive downlink control information (DCI) from the base station using a physical downlink control channel (PDCCH), the DCI comprising a DCI format differentiation bit string comprising a bit indicating a DCI format of one of a reduced-complexity DCI format or a fallback DCI format, the DCI comprising an indication of a schedule of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH);
decode the DCI based on the DCI format determined from the DCI format differentiation bit string; and
communicate on the PDSCH or the PUSCH based on the decoded DCI.
