Methods for configuration, measurement, and reporting of multiple rs resource sets for ai/ml systems

A method implemented in a wireless transmit/receive unit (WTRU), the method comprising:

• receiving, from a network, a configuration of a plurality of reference signal (RS) resource sets, wherein each RS resource set comprises one or more RS resources;
• determining to activate a subset of the plurality of RS resource sets based on one or more of:
• a comparison between a measurement time instance and a first threshold, or a comparison between a time from latest activation of at least one of the RS resources and a second threshold;
• performing measurements on the activated subset of the plurality of RS resource sets;
• and
• transmitting, to the network, a channel state information (CSI) report comprising one or more measured values and information associated with the activated subset of the plurality of RS resource sets.

A wireless transmit/receive unit (WTRU) comprising a processor configured to:

• receive, from a network, a configuration of a plurality of reference signal (RS) resource sets, wherein each RS resource set comprises one or more RS resources;
• determine to activate one or more RS resources of the plurality of RS resource sets based on a time value and a threshold;
• perform measurements on the activated one or more RS resources;
• and
• transmit, to the network, a channel state information (CSI) report comprising one or more measured values and information associated with the activated one or more RS resources.
