Abstract
A method of a relay user equipment (UE) can include receiving, at the relay UE, from a first neighbor UE, a communication request message for establishing a connection between an initiating UE and a target UE, the communication request message including first security-establishment-related information originating from the initiating UE for establishing a security association between the initiating UE and the target UE; modifying the communication request message to add second security-establishment-related information for establishing a security association between the relay UE and a second neighbor UE; and transmitting to the second neighbor UE the modified communication request message that includes the first security-establishment-related information originating from the initiating UE for establishing the security association between the initiating UE and the target UE, and the second security-establishment-related information added by the relay UE for establishing the security association between the relay UE and the second neighbor UE.
