Abstract

Methods, apparatus, and systems for a wireless transmit receive unit (WTRU) performing relay communications are provided. A method may include receiving a first message indicating: (1) a first security policy associated with a first data link, and (2) a maximum data rate for integrity protection (MDRIP) supported by the remote WTRU; transmitting, to a network, a second message indicating: (1) an MDRIP supported by the remote WTRU or by the relay WTRU, and (2) a request for PDU session establishment; receiving, from the network, a third message indicating a second security policy for a second data link; and establishing the first data link with the remote WTRU on the condition that an end-to-end (e2e) security policy is compatible with the second security policy, wherein the e2e security policy is determined according to the second security policy and a UP security policy of the relay WTRU.
