1. A wireless transmit/receive unit, WTRU, comprising circuitry configured to:
establish a connection with a relay WTRU;
establish a connection with a network via the relay WTRU;
receive a radio resource control, RRC, indication for a state change of the WTRU from a first RRC state to a second RRC state, wherein the first RRC state is different from the second RRC state;
change state from the first RRC state to the second RRC state;
in response to the state change, transmit paging information to the relay WTRU, wherein the paging information comprises WTRU discontinuous reception, DRX, cycle information when the second RRC state is either an RRC Idle state or an RRC Inactive state, wherein:
when the second RRC state is the RRC inactive state, the transmitted DRX cycle information is a minimum value of (i) a non-access stratum configured DRX cycle of the WTRU, and (ii) an RRC configured DRX cycle of the WTRU, and
when the second RRC state is the RRC idle state, the transmitted DRX cycle information is to be the non-access stratum configured DRX cycle of the WTRU.
