Claim 7:
8. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving a physical downlink control channel (PDCCH) transmission, wherein the PDCCH transmission indicates which of a first set of resources or a second set of resources is to be used by the WTRU;
determining reference signals to use for radio link monitoring (RLM) based on the received PDCCH transmission, wherein a first set of reference signals is used for RLM responsive to the PDCCH transmission indicating that the first set of resources is to be used by the WTRU and a second set of reference signals is to be used for RLM responsive to the PDCCH transmission indicating that the second set of resources is to be used by the WTRU, wherein the first set of reference signals comprise at least one of a channel state information reference signal (CSI-RS) or a synchronization signal;
performing RLM measurements using the first set of reference signals if the first set of resources is used by the WTRU, or performing RLM measurements using the second set of reference signals if the second set of resources is used by the WTRU; and responsive to a determination that a radio link quality based on the RLM measurements is below a threshold, sending a message that indicates a request for a radio resource control (RRC) procedure.
