[0046] In some embodiments, the intra-donor CU (control unit) migration process can have the source and target parent nodes served by the same IAB donor CU. Inter-donor CU partial migration can have a static migration IAB node.

[0047] In some embodiments of the present disclosure, inter-donor migration in a mobile IAB use case is discussed.

[0048] Figure 1 A mobile IAB scenario is shown. In the mobile IAB use case, the IAB node may be installed in a vehicle and may provide 5G coverage and / or capacity enhancement to the UEs (user equipment) on board and / or around the vehicle. Figure 1 In the drawings, a train is shown as an exemplary vehicle, but the present invention is also applicable to other modes of transportation.

[0049] In some embodiments, IAB can implement wireless relay in NG-RAN (Next Generation Radio Access Network). Relay nodes called IAB nodes support access and backhaul via NR. The terminal node of NR backhaul on the network side is called IABdonor, which represents gNB (gNodeB) with additional functions to support IAB. Backhaul can be performed via single hop or multi-hop. IAB architecture is as follows Figure 2 a) and Figure 2 b).

[0050] In some embodiments, the IAB node may support a gNB-DU (distributed unit) function to terminate the NR access interface to the UE and the next hop IAB node on the IAB donor and terminate the F1 protocol to the gNB-CU (central unit) function. The gNB-DU function on the IAB node is also referred to as IAB-DU.

[0051] In some embodiments, in addition to the gNB-DU functionality, the IAB node may also support a subset of UE functionality called IAB-MT (Mobile Terminal), which includes, for example, physical layer, layer 2, RRC (Radio Resource Control), and NAS (Non Access Stratum) functionality to connect to the gNB-DU of another IAB node or an IAB donor, to connect to the gNB-CU on the IAB donor, and to the core network.

[0052] In some implementations, the IAB node can access the network using SA (Standalone) mode or EN-DC (E-UTRAN New Air Interface - Dual Connectivity). In EN-DC, the IAB node is also connected to the MeNB (Master eNodeB) via E-UTRA, and the IAB donor terminates X2-C as an SgNB (Secondary gNodeB).

[0053] In some embodiments, all IAB nodes connected to the IAB donor via one or more hops form a directed acyclic graph (DAG) topology, with the IAB donor at its root (see Figure 3 ). In this DAG topology, the neighbor nodes on the IAB-DU interface are called child nodes, and the neighbor nodes on the IAB-MT interface are called parent nodes. The direction toward the child nodes is further called downstream, and the direction toward the parent node is called upstream. The IAB donor performs centralized resource, topology, and routing management for the IAB topology.

[0054] In the following paragraphs, partial and full migration in the mobile IAB use case are discussed.

[0055] According to one embodiment, in a partial migration, migration of the IAB-MT to a parent node under a different IAB donor CU may be performed without migrating the co-located IAB-DUs and descendant IAB-nodes (if any) (ie, terminating at the initial IABdonor CU).

[0056] According to one embodiment, in a full migration, the migrating IAB node (ie, the mobile IAB node in a mobile IAB scenario) and descendant IAB nodes (if any) may migrate (RRC and F1 connected) from a first IAB donor CU to a second IABdonor CU.

[0057] The IAB donor terminated by F1 can refer to the IAB donor that terminates F1 for the IAB node, and can also be called the donor of DU.

[0058] In one embodiment, there may be two logical DUs in the mobile IAB node. The two logical DUs in the mobile IAB node may be referred to as a source logical DU and a target logical DU, or a logical DU1 and a logical DU2.

[0059] FIG. 4A to FIG. 4C Figure 2 shows examples of inter-donor migration, including partial migration and full migration. Figure 4A As shown, a partial migration is performed. The IAB-MT migrates from donorDU1 belonging to donorCU1 to donorDU2 belonging to donorCU2. However, the IAB-DU maintains its F1 connection with donorCU1 and the UE context remains in donorCU1. The F1 control plane and / or user plane traffic between donorCU1 and IAB-DU is transmitted via donorDU2.

[0060] like Figure 4B As shown, a partial migration is performed. The IAB-MT migrates from donorDU2 belonging to donorCU2 to donorDU3 belonging to donorCU3. However, the IAB-DU maintains its F1 connection with donorCU1 and the UE context remains in donorCU1. The F1 control plane and / or user plane traffic between donorCU1 and IAB-DU is transmitted via donorDU3.

[0061] like Figure 4C As shown, a full migration is performed. MT and DU migrate to the same donor. IAB-DU migrates from donorCU1 to donorCU3. UE switches from donorCU1 to donorCU3. F1 control plane and / or user plane traffic between donorCU3 and IAB-DU is transmitted via donorDU3.

[0062] In the following paragraphs, details of the present disclosure will be provided in various embodiments, but the present disclosure is not limited to the following embodiments.

[0063] Implementation Method 1

[0064] In the mobile IAB use case, the mobile IAB node may be installed in a vehicle and move with the vehicle. The mobile IAB node may perform partial migration or full migration as the mobile IAB-MT moves. In this case, the TAC (Tracking Area Code) / RANAC (RAN-based Notification Area Code) broadcast by the mobile IAB-DU cell may need to be changed (or updated) to reflect the actual location (e.g., geographic location) of the mobile IAB node after the mobile IAB node moves.

[0065] In one embodiment, the mobile IAB-DU obtains the TAC for broadcast as follows: Note that in the present disclosure, taking TAC as an example, the mobile IAB-DU can obtain the RANAC for broadcast in a similar manner.

[0066] Step 1: The parent IAB node of the mobile IAB node broadcasts TAC configuration information (eg, updated TAC configuration information) of the mobile IAB node via system information. The TAC configuration information includes at least one of the following: one or more TACs, a mobile IAB indication, a TAC of a mobile IAB cell, a dedicated TAC, or a dedicated TAC indication.

[0067] In one embodiment, before the parent IAB node of the mobile IAB node broadcasts the TAC configuration information of the mobile IAB node via system information, the parent IAB node of the mobile IAB node may receive the TAC configuration information of the mobile IAB node (eg, updated TAC configuration information) from the IAB donor via an F1 message.

[0068] Step 2: The mobile IAB-MT receives TAC configuration information (eg, updated TAC configuration information) of the mobile IAB cell from the system information, and delivers it to the co-located DU.

[0069] Step 3: The mobile IAB-DU sends its TAC configuration (eg, updated TAC configuration) to its connected IABdonor. The TAC configuration may include at least the TAC (eg, updated TAC) received from the parent IAB node of the mobile IAB node via system information.

[0070] Step 4: The mobile IAB-DU broadcasts the TAC (eg, updated TAC) received from the parent IAB node of the mobile IAB node via system information.

[0071] Implementation Method 2

[0072] Step 1: The donor of the mobile IAB-DU (i.e., the IAB donor having an F1 connection with the mobile IAB-DU) sends TAC configuration information (e.g., updated TAC configuration information) to the mobile IAB node, for example, via an F1 message. The TAC configuration information may include at least one of the following: one or more TACs, a mobile IAB indication, a TAC of a mobile IAB cell, a dedicated TAC, a dedicated TAC indication, geographic location information, or cell information. The cell information may include a gNB ID (identifier) ​​or a cell ID (e.g., PCI (physical cell ID) or NCGI (new radio cell global identity)) of the parent cell of the mobile IAB-MT, i.e., a cell belonging to the parent node of the mobile IAB-MT and serving the mobile IAB-MT.

[0073] Step 2: The mobile IAB-DU broadcasts the TAC (eg, updated TAC) received from the donor of the mobile IAB-DU via the F1 message.

[0074] Implementation 3

[0075] In one embodiment, the AMF (Access and Mobility Management Function) may need to know the TAC supported in the gNB so that the AMF can send a paging message for the UE to the appropriate gNB. In one embodiment, the AMF obtains the TAC of the mobile IAB cell as follows.

[0076] In one embodiment, a donor of a mobile IAB (e.g., a donor of a mobile IAB-MT or a donor of a mobile IAB-DU) sends a TAC configuration of a mobile IAB cell to the AMF via an NG message. The TAC configuration of a mobile IAB cell includes at least one of the following: one or more TACs, a mobile IAB indication, a TAC of a mobile IAB cell, a dedicated TAC, or a dedicated TAC indication.

[0077] Implementation 4

[0078] In one embodiment, the gNB may need to know the TAC supported in the neighbor gNB so that the gNB can send a RAN paging message for the UE to the appropriate neighbor gNB. In one embodiment, the neighbor gNB obtains the TAC of the mobile IAB cell as follows.

[0079] In one embodiment, a mobile IAB donor (e.g., a mobile IAB-MT donor or a mobile IAB-DU donor) sends a TAC configuration of a mobile IAB cell to a neighbor GNB, for example, via an Xn message. The TAC configuration of a mobile IAB cell includes at least one of the following: one or more TACs, a mobile IAB indication, a TAC of a mobile IAB cell, a dedicated TAC, or a dedicated TAC indication.

[0080] Implementation 5—Recovery of RLF between donors

[0081] Embodiments of the present disclosure solve the problem of how an initial IAB donor identifies a recovery IAB node during an IPsec (Internet Protocol Security) connection establishment phase during inter-donor backhaul RLF recovery.

[0082] Option 1:

[0083] Step 1: The recovering IAB node sends an RRC message to the new IAB donor. The IAB node indication is included in the RRC message, for example, RRC Reestablishment Request or RRC Reestablishment Request Complete message.

[0084] Step 2: The new IAB donor determines that the nodes involved in the RRC re-establishment process are IAB nodes.

[0085] Step 3: The new IAB node sends the F1-C (control plane) IP (Internet Protocol) address of the recovery IAB node to the initial IAB donor via Xn (eg, via a Retrieve UE Context Request message via Xn).

[0086] Option 2:

[0087] The new IAB donor sends the F1-C IP address of the restored IAB node to the initial IAB donor via Xn (eg, via a UE context release message or a new XnAP message). Optionally, the new IAB donor may send the F1-C IP address to the initial IAB donor after receiving the Xn retrieve UE context response message.
