1. A wireless transmit/receive unit (WTRU) comprising:
a processor configured to receive a radio resource control (RRC) message, the RRC message comprising measurement configuration information for beam failure detection, the measurement configuration information for beam failure detection indicating one or more reference signals to be used for performing beam failure detection measurements, wherein the RRC message comprises information indicative of one or more channel conditions that indicate to the WTRU to use a relaxed beam failure detection measurement period;
receive a downlink control information (DCI) format 2_0 transmission;
determine to change from a first search space set to a second search space set based on the DCI format 2_0 transmission, wherein the first search space set is associated with a first group index and the second search space set is associated with a second group index;
based on the change determination from the first search space set to the second search space set, determine to apply the relaxed beam failure detection measurement period, wherein the second group index associated with the second search space set is associated with reference signal measurement opportunities associated with the relaxed beam failure detection measurement period; and
perform one or more measurements in accordance with the relaxed beam failure detection measurement period based on the reception of the DCI format 2_0, wherein the relaxed beam failure detection measurement period is greater than a beam failure detection measurement period which is used when use of the relaxed beam failure detection measurement period is not indicated.
