Example implementations include a method, apparatus and computer-readable medium of wireless communication, including receiving a configuration of one or more downlink control information (DCI) formats to include a single bit for a redundancy version field. The implementations further include receiving a radio resource control (RRC) message indicating selectable redundancy versions. Additionally, the implementations further include detecting a DCI based on the one or more DCI formats including the single bit for the redundancy version field, the DCI scheduling a transmission. Additionally, the implementations further include selecting a redundancy version from the selectable redundancy versions based on the single bit. Additionally, the implementations further include encoding or decoding the transmission based on the redundancy version.
