1. A wireless transmit/receive unit (WTRU) comprising a processor, the processor configured to:
receive configuration information, wherein the configuration information comprises an indication of a plurality of uplink (UL) resources for a secondary cell (Scell) beam recovery, a first UL resource of the plurality of UL resources is associated with a first beam set of the SCell, and a second UL resource of the plurality of UL resources is associated with a second beam set of the Scell;
determine that beam failure has occurred on the Scell;
determine whether to indicate that beam failure has occurred on the Scell using the first UL resource or the second UL resource, wherein the processor is configured to determine to indicate that beam failure has occurred on the Scell using the first UL resource if the beam failure corresponds a beam of the first beam set of the Scell, and the processor is configured to determine to indicate that beam failure has occurred on the Scell using the second UL resource if the beam failure corresponds a beam of the second beam set of the Scell; and
send a transmission using the determined first or second UL resource based on determining that beam failure has occurred on the Scell.
