Methods, architectures, apparatuses and systems for device association over direct communication for aggregated devices

A method implemented by a first wireless transmit receive unit (WTRU) comprising:

• receiving a first message comprising an aggregation revocation configuration notification indicating a first identifier of a second WTRU to be revoked from multiple WTRUs associated with an aggregation of the first WTRU;
• transmitting a revocation request message to the second WTRU;
• and
• transmitting, to a third WTRU from the multiple WTRUs an aggregation revocation notification including the first identifier, wherein the aggregation revocation notification comprises first information indicating releasing any resources associated with the second WTRU.

A first wireless transmit/receive unit (WTRU) comprising a processor, a transceiver unit and a storage unit, and configured to:

• receive a first message comprising an aggregation revocation configuration notification indicating a first identifier of a second WTRU to be revoked from multiple WTRUs associated with an aggregation of the first WTRU;
• transmit a revocation request message to the second WTRU;
• and
• transmit, to a third WTRU from the multiple WTRUs, an aggregation revocation notification including the first identifier, wherein the aggregation revocation notification comprises first information indicating releasing any resources associated with the second WTRU.
