Abstract: Methods for determining candidate beams for beam failure recovery are provided herein. A method performed by a wireless transmit/receive unit (WTRU) includes receiving configuration information for receiving a first set of reference signals that are associated with a first set of beams, receiving configuration information for receiving a second set of reference signals that are associated with a second set of beams, and one or more criteria for candidate beam selection. The method includes receiving at least one of the first set of reference signals. The method includes transmitting information indicating a selected third set of beams that satisfy the received criteria for candidate beam selection. The selected third set of beams is a suggested set of candidate beams to be monitored for beam failure recovery.

Abstract: A wireless transmit/receive unit (WTRU) may receive a set of channel state information (CSI) report configurations that may be associated with one or more functionalities associated with an AIML model.

Abstract: A wireless transmit/receive unit (WTRU) may be configured to perform measurements and measurement predictions in an idle state or an inactive state (e.g., low-power operation mode). The WTRU may perform measurements for the configured idle measurement durations. If the WTRU stays in the idle state or the inactive state for more than a validity duration after it has stopped performing measurements, the WTRU may perform measurement predictions. Upon transitioning to a CONNECTED state (full-power operation mode), the WTRU may report the actual measurements, if they are still valid, or otherwise, report the predicted measurements.

Abstract: Systems and methods for predictive wireless communication management. In some implementations, a wireless transmit/receive unit (WTRU) may establish communications with a network node via a first physical communication channel; and determine that a difference between measured characteristics of a reference signal and measured characteristics of a previous reference signal exceeds a reporting threshold. The WTRU may transmit, to the network node responsive to the determination, an identification of the measured characteristics of the reference signal; and may receive, from the network node via the first physical communication channel, an indication of predicted beam failure generated responsive to receipt of the identification of measured characteristics of the reference signal. The WTRU may reconfigure, responsive to receipt of the indication of predicted beam failure, communications with the network node to utilize a second physical communication channel.
