Apparatuses, methods, and systems are disclosed for downlink assignments for downlink control channels. One method includes determining a third set of downlink control channel monitoring occasions that comprises first downlink control channel monitoring occasions and second downlink control channel monitoring occasions, and associated search spaces correspond to two different control resource sets comprising a first control resource set and a second control resource set, wherein: demodulation reference signal ports of the first control resource set are quasi-collocated with a first set of reference signals; demodulation reference signal ports of the second control resource set are quasi-collocated with a second set of reference signals. The method includes monitoring one or more downlink control channel candidates in at least one slot of the third set of monitoring occasions if the one or more downlink control channel candidates carry the same downlink control information.
