Abstract

A first and second UE are connected via a PC5 unicast link. Both maintain a list of potential Side link relay UEs and agree on a common list of UEs that appear in both lists. When the first UE detects that the second UE has trouble receiving it's transmission, e.g. ack/nack timeout or high level of NACKs, decide to use a third UE from the common list as Side Link relay towards the second UE.
