Liu,Fig. 15 [0234]; The donor CU determines, based on a RAN notification area configured for the inactive UE, a cell identifier NR CGI of all IAB DUs in the area, and then determines, based on a correspondence between an IAB DU cell identifier NR CGI and an IAB MT identifier I-RNTI, an IAB MT in all inactive states in the RAN notification area, or determines, based on a RAN notification area configured for the inactive UE, a cell identifier NR CGI of all IAB DUs in the area, and then determines, based on a correspondence between an identifier DU ID of the IAB DU and a cell identifier NR CGI of the IAB DU, all IAB DUs in the area, and finally determines, based on a correspondence between the identifier DU ID of the IAB DU and the IAB MT identifier I-RNTI, the IAB MT in all inactive states in the RAN notification area.
and the switching, by the node, to the target state based on the target information comprises:
establishing, by the node, a wireless connection to the network side device;
Liu, [0240]; For the idle state UE, the authentication management function (AMF) network element of the core network generates the NG paging message and sends the NG paging message to the host CU through the NG interface. Then, the donor CU generates the F1 paging message based on the received NG paging message (based on target information), and sends the F1 paging message to the IAB DU through the F1 interface (wireless connection to the network side).The IAB DU generates the paging message of the final RRC layer based on the F1 paging message and sends the paging message to the UE.
and switching, by the node, the radio frequency module to an on state.
Liu, [0237];After the RRC connection is restored, the fast F1 interface recovery process between the IAB-DU and the host CU will be triggered. For example, after the donor CU learns cell information of the IAB DU, once the donor CU learns that the RRC connection with the IAB MT is restored, the donor CU sends an F1 interface recovery message to the IAB DU, where the message carries the activation indication information of the IAB DU cell, that is, indicates which IAB DU cells are activated.
In view of Liu, Zhuo is modified such that target information comprises an inactive radio network
temporary identifier (I-RNTI)-based paging signal on a radio access network (RAN) side that is sent by a
network side device;
Zhuo and Liu are analogous art to the claimed invention because they are in the same field of
endeavor, determining working states of IAB node.
It would be obvious before the effective filing date of claimed invention, to a person ordinary skill in the
art to modify Zhuo in the manner described above to demonstrate the more specific steps to turn the DU back on active state.
Regarding claim 18, Zhuo teaches all the limitation of claim 12. The method according to claim 12, wherein the indication information comprises an inactive radio network temporary identifier (I-RNTI)-based paging signal on a radio access network (RAN) side; or information used to indicate a switching time point.
Liu, Fig. 15 [0223]; In step S1301, the donor CU receives the DL data or the paging message sent by the core network element.
Liu,Fig. 15 [0227]; At step S1303, the donor CU sends a paging message for the IAB-MT.
Liu,Fig. 15 [0234]; The donor CU determines, based on a RAN notification area configured for the inactive UE, a cell identifier NR CGI of all IAB DUs in the area, and then determines, based on a correspondence between an IAB DU cell identifier NR CGI and an IAB MT identifier I-RNTI, an IAB MT in all inactive states in the RAN notification area, or determines, based on a RAN notification area configured for the inactive UE, a cell identifier NR CGI of all IAB DUs in the area, and then determines, based on a correspondence between an identifier DU ID of the IAB DU and a cell identifier NR CGI of the IAB DU, all IAB DUs in the area, and finally determines, based on a correspondence between the identifier DU ID of the IAB DU and the IAB MT identifier I-RNTI, the IAB MT in all inactive states in the RAN notification area.

Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over Zhuo in view of Liu in further view Gan et al. (US 2021/0168713 A1) (“Gan”).
Regarding claim 11, Zhuo teaches all the limitation of claim 1. The method according to claim 1, establishing, by the node, a wireless connection to the network side device;
Liu, [0240]; For the idle state UE, the authentication management function (AMF) network element of the core network generates the NG paging message and sends the NG paging message to the host CU through the NG interface.
