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. The WTRU may determine, based on one or more conditions, that a first functionality of the one or more functionalities is non-applicable. The WTRU may transmit a first indication (e.g., via MAC-CE) that the first functionality is non-applicable to the network. The WTRU may start a timer upon determining that the first functionality is non-applicable. The WTRU may transmit one or more CSI reports that include predicted (e.g., inaccurate). The WTRU may determine that the timer has expired, and may transmit a second indication (e.g., via RRC) that the functionality is non-applicable. The WTRU may receive an indication to fallback to non-AIML operation and/or an indication to use an applicable second functionality of the one or more functionalities.

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.
