1. A wireless transmit/receive unit (WTRU), the WTRU comprising:
a processor, the processor configured to:
determine a first set of control channel elements (CCEs) from a plurality of CCEs, wherein the first set of CCEs is associated with a first beam and a first search space (SS), and wherein the first SS is associated with a first control resource set (CORESET);
determine a second set of CCEs from the plurality of CCEs, wherein the second set of CCEs is associated with a second beam and a second SS, and wherein the second SS is associated with a second CORESET;
determine that the first set of CCEs is associated with the second set of CCEs;
receive at least one of a first physical downlink control channel (PDCCH) transmission using the first beam and the first set of CCEs, or a second PDCCH transmission using the second beam and the second set of CCEs; and
decode a downlink control information (DCI) using the at least one of the first PDCCH transmission or the second PDCCH transmission.
