Make-before-break procedures for establishing pc5 link

Abstract

Methods for protocol data unit (PDU) session establishment or modification utilizing make-before-break behavior are provided herein. A method performed by a remote wireless transmit/receive unit (WTRU) includes sending or receiving, over a first link to a relay WTRU, PDUs including a first internet protocol (IP) address associated with a first PDU session utilizing session service and continuity mode 3(SSC3). The method includes receiving, over the first link to the relay WTRU, a link indication message requesting establishment of a second link and sending a message to establish the second link with the relay WTRU prior to release of the first link to the relay WTRU. The method includes sending or receiving PDUs over the second link to the relay WTRU including a second IP address associated with the second PDU session utilizing SSC3.
