receiving, by the second UE, a DRX configuration transmitted by the BS which is determined by the BS based on the list of preferred DRX configurations,
wherein the first UE is a relay UE,
wherein the assistance information including the list of preferred DRX configurations has higher priority than other assistance information,
wherein based on the DRX configuration being not determined from the list of preferred DRX configurations, a cause value is received along with the DRX configuration.
