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 at least a first threshold value and a second threshold value used for determining whether to use a relaxed second beam failure detection measurement period;
perform one or more first measurements to evaluate for beam failure detection in accordance with a first beam failure detection measurement period;
determine that an L1 channel quality measurement value is greater than the first threshold value;
determine that a change in reference signal received power (RSRP) is less than the second threshold value, wherein the change in RSRP corresponds to an L3/mobility-based measurement value;
determine to evaluate for beam failure detection in accordance with the second beam failure detection measurement period based on the L1 channel quality measurement value being greater than the first threshold value and based on the change in RSRP being less than the second threshold value, wherein the second beam failure detection measurement period is greater than the first beam failure detection measurement period; and
perform one or more second measurements to evaluate for beam failure detection in accordance with the second beam failure detection measurement period based on the L1 channel quality measurement value being greater than the first threshold value and based on the change in RSRP being less than the second threshold value.
