Abstract
In examples, the E2E link IDs may be isolated per-hop, so that changes of link IDs may not impact other E2E/per-hop links (e.g., a LIU procedure may only run between a WTRU and the relay). A relay may allocate R-specific security IDs/session key identifiers (e.g., MSBs/LSBs of Knrp-sess ID). The relay (e.g., relay WTRU) may replace the security IDs/session key identifiers received from peer WTRUs with R-specific security IDs/session key identifiers, for example, if forwarding a message. In examples, per-hop IDs and E2E IDs may be added to link identifier update messages. In examples, the support application layer ID and IP address/prefix may be changed using a link modification procedure (e.g., between E2E peer WTRUs), which may be executed during the LIU procedure run between a WTRU and a WTRU-to-WTRU relay.
