A method comprising: receiving a first indication comprising a first search space identity and a second search space identity, wherein the first search space identity and the second search space identity are for a set of associated search spaces comprising a first search space and a second search space; determining a first set of downlink control channel monitoring occasions for the first search space; determining a second set of downlink control channel monitoring occasions for the second search space; determining a third set of downlink control channel monitoring occasions corresponding to the associated search spaces, wherein the third set of downlink control channel monitoring occasions comprises a subset of the first downlink control channel monitoring occasions and the second set of downlink control channel monitoring occasions, the associated search spaces correspond to two different control resource sets comprising a first control resource set and a second control resource set, and 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; and the first set of reference signals and the second set of reference signals are different; and 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. receiving a first indication comprising a first search space identity and a second search space identity, wherein the first search space identity and the second search space identity are for a set of associated search spaces comprising a first search space and a second search space; determining a first set of downlink control channel monitoring occasions for the first search space; determining a second set of downlink control channel monitoring occasions for the second search space; determining a third set of downlink control channel monitoring occasions corresponding to the associated search spaces, wherein the third set of downlink control channel monitoring occasions comprises a subset of the first downlink control channel monitoring occasions and the second set of downlink control channel monitoring occasions, the associated search spaces correspond to two different control resource sets comprising a first control resource set and a second control resource set, and 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; and the first set of reference signals and the second set of reference signals are different; and 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; and the first set of reference signals and the second set of reference signals are different; and 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.
