1. A network node configured to communicate with a wireless device (WD) according to the Third Generation Partnership Project (3GPP) New Radio (NR), the network node comprising processing circuitry configured to:
determine whether the WD is configured to monitor a downlink control information (DCI) format 0_2 or 1_2 for ultra-reliable low latency communications (URLLC); and
when the WD is configured to monitor a DCI format 0_2 or 1_2 for URLLC, then perform a DCI size alignment procedure to adjust a size of URLLC DCI format 0_2 or 1_2 in a WD-specific search space, wherein the size of URLLC DCI format 0 2 or 1 2 in the WD-specific search space after being aligned does not equal the size of DCI format 01 or 1_1 in another WD-specific search space.
