[0019] The section headings used in this document are for ease of understanding only and do not limit the scope of the embodiments to the sections describing them. Furthermore, while embodiments are described with reference to 5G examples, the disclosed techniques can be applied to wireless systems using protocols other than 5G or 3GPP protocols.

[0020] Figure 1 An example of a wireless communication system (e.g., a Long Term Evolution (LTE), 5G, or NR cellular network) including a BS 120 and one or more user equipment (UE) devices 111, 112, and 113 is shown. In some embodiments, uplink transmissions (131, 132, 133) may include uplink control information (UCI), higher-layer signaling (e.g., UE assistance information or UE capabilities), or uplink information. In some embodiments, downlink transmissions (141, 142, 143) may include DCI or higher-layer signaling or downlink information. The UE may be, for example, a smartphone, tablet, mobile computer, machine-to-machine (M2M) device, terminal, mobile device, Internet of Things (IoT) device, etc.

[0021] Figure 2 This is a block diagram representation of a portion of an apparatus based on some embodiments of the disclosed technology. Apparatus 205, such as a network device, base station, or wireless device (or UE), may include processor electronics 210, such as a microprocessor implementing one or more technologies proposed in this document. Apparatus 205 may include transceiver electronics 215 for transmitting and / or receiving wireless signals via one or more communication interfaces, such as antenna 220. Apparatus 205 may include other communication interfaces for transmitting and receiving data. Apparatus 205 may include one or more memories (not explicitly shown) configured to store information such as data and / or instructions. In some implementations, processor electronics 210 may include at least a portion of transceiver electronics 215. In some embodiments, apparatus 205 is used to implement at least some of the disclosed technologies, modules, or functions.

[0022] Radio access and backhaul architectures, such as Integrated Access and Backhaul (IAB) or Radio Access Backhaul (WAB), support radio access and backhaul via NR (New Radio), enabling flexible and dense deployment of NR cells while reducing the need for wired transmission infrastructure.

[0023] In some embodiments, the disclosed techniques may be implemented to provide methods and systems for resource reuse at WAB nodes and for service forwarding via a gateway (GW) for femtonodes.

[0024] Figure 3 An example of a wireless access and backhaul architecture is shown.

[0025] Relay nodes (e.g., IAB or WAB nodes) can support access and backhaul via NR. The terminating node of the network-side NR backhaul is called the donor node, which represents a gNB with additional capabilities to support radio access and backhaul. Backhaul can occur via single hops or multiple hops. Figure 3 An example of a wireless access and backhaul architecture is shown in the diagram. Figure 3 In this configuration, the UE connects to the network via the WAB node. UE services between the UE and its users' plane functions (UPF) are forwarded via the UPF of the WAB node, the WAB donor node, and the optional MT (Mobile Terminal). In another example, the MT's UPF can be co-located with the WAB donor node.

[0026] WAB nodes support gNB functionality to provide NR access to UEs and terminate Xn / NG protocols (e.g., interfaces between NG-RAN nodes) to donor nodes, AMF (Access Management Function), and / or UPF. In addition to gNB functionality, relay nodes also support a subset of UE functions known as MT, including, for example, physical layer, Layer 2, Radio Resource Control (RRC), and Non-Access Stratum (NAS) functions, to connect to another WAB node or WAB donor node, and to connect to the core network.

[0027] Resource reuse Figure 4A This example scenario illustrates a single WAB-MT connection to a WAB donor node. Figure 4B An example scenario is shown where WAB-MT is dual-connected with two WAB donor nodes. Figure 4C An example scenario is shown where WAB-MT and WAB-gNB are connected to two different donor nodes. In some implementations, the term "WAB-MT" can be used to indicate the MT function of the WAB, and the term "WAB-gNB" can be used to indicate the gNB function of the WAB.

[0028] The following situations can be considered in R19 WAB: Scenario 1: WAB-MT has a single connection to a WAB donor node.

[0029] Scenario 2: WAB-MT with dual connections to two WAB donor nodes.

[0030] Scenario 3: WAB-MT performs a migration, with WAB-MT and WAB-gNB connected to two different donor nodes. For example, WAB-MT is served by the target donor node, while WAB-gNB is controlled by the source donor node.

[0031] Problem: If a WAB node's WAB-gNB and WAB-MT are subject to half-duplex constraints, then during the transmission / reception of another node, correct transmission / reception by one node cannot be guaranteed, and vice versa, for example, when operating at the same frequency. The question is how to achieve resource multiplexing between the WAB-MT and its co-located WAB-gNB. In some implementations, the term "half-duplex" can be used to describe a communication method that allows data to be transmitted in both directions, but only in one direction at a time.

[0032] Solution 1: Step 1: The WAB donor node sends cell resource configuration to the WAB node, for example via the Xn message.

[0033] In some implementations, cell resource configuration includes at least one of the following: resource configuration of gNB-DU (Distributed Unit) cells, resource configuration of neighboring cells, identifiers of neighboring cells, frequency information, transmission bandwidth, carrier list, and unavailable (NA) resource configuration of the serving cell for co-location of WAB-MT. Resource configuration includes at least one of the following: subcarrier spacing, downlink / uplink / flexible (DUF) transmission period, DUF timeslot configuration, hard / soft / unavailable (HSNA) transmission periodicity, HSNA timeslot configuration, resource block (RB) set configuration, and frequency domain HSNA configuration. Resource configuration includes frequency division duplex (FDD) uplink (UL) or FDD downlink (DL) or time division duplex (TDD) configuration.

[0034] Step 2: The WAB-gNB communicates with the UE based on the cell resource configuration received from the WAB donor node.

[0035] Solution 2: Step 1: The WAB node sends cell-specific signaling or channel configuration to the WAB donor node via RRC or Xn messages. In some implementations, the cell-specific signaling or channel configuration includes at least one of the following: Synchronization Signal Block (SSB) transmission configuration (STC), Random Access Channel (RACH) general configuration, Channel State Information (CSI) Reference Signal (CSI-RS) configuration, Scheduling Request (SR) configuration, Physical Downlink Control Channel (PDCCH) configuration SIB1, General Subcarrier Spacing (SCS), and multiplexing information (e.g., information about multiplexing with cells configured for co-configuring WAB-MT).

[0036] Step 2: The WAB donor node performs resource reuse based on cell-specific signaling or channel configuration received from the WAB node. For example, the WAB donor node treats these resources as hard resources and does not use these resources simultaneously on the link between the WAB donor node and WAB-MT, thereby achieving resource reuse at the WAB node while avoiding interference.

[0037] Solution 3: Step 1: The WAB node sends the STC configuration information of the WAB-gNB, or the duplex constraint information between the WAB-MT and the co-located WAB-gNB, to the WAB donor node via the Xn Application Protocol (XnAP) message. Alternatively, the WAB node indicates to the WAB donor node via XnAP whether frequency division multiplexing (FDM) is needed for enhanced multiplexing operations.

[0038] Step 2: The WAB donor node reuses resources based on the information received from the WAB node.

[0039] NG-C service forwarding of femtonodes Figure 5 An example network architecture including femtonodes is shown.

[0040] Problem: Femtonodes are primarily deployed in home or enterprise settings. Femtonodes have a very small coverage area, so a large number of 5G femtonodes should be scalable in this context. The question is how to scalably support NG connectivity for femtonodes.

[0041] Solution 1: The femtonode sends an NG message to the Access and Mobility Management Function (AMF). The femtonodes are connected to the gateway (GW) via Next Generation (NG) connections, and Next Generation Application Protocol (NGAP) signaling between the femtonodes and the AMF is forwarded via the GW.

[0042] Step 1: The femtonode sends a first NGAP message to the GW. Optionally, the first NGAP message includes a second NGAP message. The first NGAP message includes routing information. In some implementations, the routing information includes at least one of the following: the identifier of the target AMF, and the identifier of the source next-generation radio access network (NG RAN) node (e.g., the femtonode).

[0043] If the first NGAP message contains neither the second NGAP message nor the identifier of the target AMF, then the GW stores the mapping information between the identifier of the received source NG RAN node and the IP address of the node that sent the NGAP message.

[0044] Step 2: Optionally, the GW routes the message to the appropriate AMF based on the identifier of the target AMF. Optionally, the target AMF replies using the identifier of the source NG RAN node; for example, the target AMF includes the received identifier of the source NG RAN node as the identifier of the target NG RAN node in the reply NGAP message.

[0045] Solution 2: AMF sends NG messages to femtonodes Figure 6 An example of next-generation (NG) routing via the Next Generation Application Protocol (NGAP) is shown.

[0046] The femtonode connects to the gateway (GW) via NG connection, and NGAP signaling between the femtonode and AMF is forwarded via GW.

[0047] Step 1: The AMF sends a first NGAP message to the GW. Optionally, the first NGAP message includes a second NGAP message. The first NGAP message includes routing information. In some implementations, the routing information includes at least one of the following: the identifier of the target NG RAN node (e.g., a femtonode) and the identifier of the source AMF.

[0048] If the first NGAP message contains neither the second NGAP message nor the identifier of the target NG RAN node, the GW stores the mapping information between the received source AMF identifier and the IP address of the sending node of the NGAP message.

[0049] Step 2: Optionally, the GW routes the message to the appropriate NG RAN node based on the identifier of the target NG RAN node. Optionally, the target NG RAN node replies using the identifier of the source AMF; for example, the target NG RAN node includes the received source AMF identifier as the identifier of the target AMF in the reply NGAP message.

[0053] In some implementations, the process 800 for wireless communication may include, at 810, the second network node receiving from the first network node via a first message cell-specific signaling or channel configuration used in the link between the first network node and the mobile device, and at 820, the second network node determining, based on the cell-specific signaling or channel configuration, the resources to be used in the link between the second network node and the mobile terminal (MT) portion of the first network node.

[0054] Figure 9 Another example of a wireless communication process based on some example embodiments of the disclosed technology is shown.

[0055] In some implementations, the process 900 for wireless communication may include, at 910, a first node sending a first signaling message to a network connector, and at 920, a first node receiving a response message from the network connector.
