Methods, architectures, apparatuses and systems for AI/ML model distribution

A first wireless transmit/receive unit (WTRU), the first WTRU comprising circuitry, including a transmitter, a receiver, a processor and a memory and being configured to:

• send, to a network entity, a subscription request for downloading an AI/ML model, the AI/ML model comprising a first model portion, and one or more further model portions;
• determine a second WTRU storing at least the first model portion of the AI/ML model;
• send, to the network entity, first information comprising an indication of the second WTRU;
• receive, from the network entity, second information indicating a schedule for downloading at least the first model portion of the AI/ML model from the second WTRU;
• download, from the second WTRU via a device-to-device communication between the first WTRU and the second WTRU, at least the first model portion of the AI/ML model at a scheduled time using the second information, wherein the first model portion is a base AI/ML model of the AI/ML model;
• and
• generate inference results using the at least first model portion.
