The technical scheme of the embodiment of the application can be applied to various communication systems, including but not limited to: the fifth generation (the 5th generation, 5G) system or new wireless (NR) system, long term evolution (long term evolution, LTE) system, LTE frequency division duplex (frequency division duplex, FDD) system, LTE time division duplex (time division duplex, TDD) system, code division multiple access (code division multiple access, CDMA), wireless fidelity (wireless fidelity, WIFI), device-to-device (D2D) communication system, vehicle-to-device (V2X) communication system, machine-to-machine (machine to machine, M2M) communication system, machine type communication (machine type communication, MTC) system, internet of things (internet of things, ioT) communication system, and future communication systems, such as sixth generation mobile communication system, etc.

A network architecture suitable for use with the present application will first be briefly described.

As an example, fig. 1 shows a schematic diagram of an IAB radio access network side networking.

As shown in fig. 1, in an IAB network, a Relay Node (RN), also called an IAB-node (IAB-node), may provide a radio access service for a User Equipment (UE). The UE is connected to an IAB-node via a radio access link, and traffic data of the UE is connected by the IAB-node to an IAB-hosting base station (IAB-node) via a radio backhaul link, and is accessed to a core network (e.g., a 5G core network) via the IAB-node. The IAB-node is composed of a mobile terminal (mobile termination, MT) part and a Distributed Unit (DU) part, wherein the IAB-node can be used as a terminal device, i.e. the role of MT, when facing its parent node; an IAB-node is considered a network device when it is towards its child node (which may be another IAB-node, or a generic UE), i.e. takes on the role of a DU. The Centralized Unit (CU) section of the IAB network is located in the IAB-donor. The home base station is also referred to herein as a home node, i.e., IAB-donor node.

Fig. 2 shows a schematic diagram of a system architecture suitable for use with embodiments of the present application. As shown in fig. 2, the IAB (or referred to as an IAB device) is a wireless backhaul base station, which is specific in that the IAB first establishes a backhaul channel with a target macro station, and then provides wireless coverage service to the outside, similar to the customer premise equipment (customer premise equipment, CPE), except that the CPE provides wireless fidelity (wireless fidelity, WIFI) coverage to the outside. The IAB provides base station radio signals, such as fifth generation (the fifth generation, 5G) signals, externally. The IAB is mainly used as coverage extension of the macro station, and by means of the characteristics of high-power multi-antenna reception of its backhaul device, the remote coverage of the macro station is extended, changing the weak coverage area that is originally a far point for the macro station into a good coverage area of a near-middle point. The IAB generally requires accurate access to the target macro station to establish a backhaul path due to the connection relationship with the fixed macro station.

In the IAB network architecture illustrated in fig. 2, for example, independent networking (SA) networking is taken as an example, the IAB-donor may be formed of a Centralized Unit (CU) and a Distributed Unit (DU), that is, splitting functions of the IAB-donor, deploying part of the functions on one CU, deploying the rest of the functions on the DU, and sharing one CU by a plurality of DUs, cost may be saved, and network expansion may be facilitated. The CU and the DU are connected through an F1 interface. CU stands for IAB-donor connected to core network via Next Generation (NG) interface, CU stands for IAB-donor connected to other gNB via Xn interface.

The IAB-node DU is logically connected to the IAB-donor CU through an F1 interface, and in fact, the connection of the IAB-node DU to the IAB-donor CU is implemented through an NR Uu interface between the IAB-node MT and the parent node DU of each hop, but since the final IAB-node DU can communicate with the IAB-donor CU, it can be considered that an F1 interface logically exists, both of which can interact with control plane (F1-control plane, F1-C) information and user plane (F1-U) information through the F1 interface. The IAB-nodmt function is defined as a component like a UE. In an IAB network, an MT is referred to as a function residing on an IAB-node. Since the MT functions like a normal UE, the IAB-node can be considered to be accessed to a higher node or network through the MT.

The present application refers to the following network elements/modules:

1. IAB node: for providing access to a child node or UE and wireless backhaul services.

2. IAB-donor (or host node called host node or IAB node): the base station supporting the IAB node may specifically include an IAB-donorCU and at least one IAB-donorDU. Alternatively, the IAB-donor CU may comprise one IAB-donor CU-CP, and at least one IAB-donor CU-UP. Wherein IAB-donor-CU-CP and IAB-donor-CU-UP represent the Control Plane (CP) and User Plane (UP) of the IAB-donor CU, respectively.

3. gNB: and the 5G type base station is used for providing access and backhaul service for the child node or the UE.

The following description or description is given in terms of technical terms or concepts related to the present application, which are convenient for reading.

1. Local migration (partial migration):

when the load at the IAB-node1 is too heavy and the load at the IAB-node3 is light, the network device may control the IAB-node MT2 to migrate from the cell under the IAB-node DU1 to the cell under the IAB-node DU3, wherein the IAB-node DU1 and the IAB-node DU3 are controlled by the IAB-donocu 1 and the IAB-donocu 2, respectively. When the IAB-node MT2 migrates to the IAB-node DU3 controlled by the IAB-donor CU2, the IAB-node DU2 and its child nodes still maintain the F1 interface with the IAB-donor CU1, but do not establish the F1 interface with the IAB-donor CU 2.

The IAB-donor CU1 and the IAB-donor CU2 can interact resource configuration information about the IAB-node2 through the Xn interface, and then when in switching, the IAB-donor CU1 reconfigures the resources of the IAB-node2 through the F1 interface to enable the IAB-donor CU1 to be consistent with the resource configuration under the IAB-DU3, namely no resource conflict occurs, or the IAB-donor CU2 reconfigures the resources of the IAB-DU3 through the F1 interface to enable the IAB-donor CU2 to be consistent with the resource configuration in use of the IAB-node2, namely no resource conflict occurs. The resource information configured through Xn interface interaction and F1 interface mainly comprises two types: general resource information (e.g., random access channel (random access channel, RACH) resources, system information block 1 (system information block, sib1) resources, etc.), TDD/FDD resource configuration information (e.g., frequency point configuration, bandwidth configuration, slot configuration, etc.).

2. Automatic neighbor relation technique (automatic neighbor relation, ANR):

in the operation and maintenance of the LTE and 5G networks, an ANR technology can be adopted, so that the network can automatically find the neighbor relation, and manual configuration is reduced.

The main processes of the ANR technology are: firstly, through the normal neighbor cell measurement process of UE, the synchronization signal and the physical broadcast channel block (synchronization signal and physical broadcast channel block, SSB) of the neighbor cell are measured, normal measurement report is carried out, and the measurement report carries the physical cell identification (physical cell identifier, PCI) information of the neighbor cell. If the gNB finds that the neighbor cell is not maintained in the neighbor cell list according to the PCI information of the neighbor cell, the neighbor cell is considered to be a missed neighbor cell, the UE stops the current communication process and performs measurement again, the measurement of the UE needs to receive SIB1 information of the neighbor cell, including information of NR cell global identifiers (NR cell global identifier, NCGI), tracking area codes (tracking area code, TAC), radio network area codes (RAN) and PCI, public land mobile network (public land mobile network, PLMN) lists and the like of the neighbor cell, and the information is put into a measurement report and reported to the gNB, so that the gNB finds the neighbor cell relation.

3. Operation maintenance management (operation administration and maintenance, OAM):

OAM refers to three general categories of network management according to the actual needs of the operator's network operation: operation, management, maintenance. The operation mainly completes analysis, prediction, planning and configuration work of daily network and business; maintenance is mainly a daily operation activity performed on testing and fault management of a network and services thereof.

It should be noted that the above terms or techniques are all of the prior art and are not limiting.

It will be appreciated that the term "and/or" is merely one association relationship describing the associated object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

The terms related to the present application are briefly described above, and will not be repeated in the following examples. The communication method provided by the embodiment of the application will be described in detail below with reference to the accompanying drawings. The embodiments provided in the present application may be applied to the network architecture shown in fig. 1 and fig. 2, and are not limited thereto.

Based on the architecture shown in fig. 1 and fig. 2, the assistance of the UE can be utilized by the ANR mechanism, so that the base station discovers the neighbor cell which is missed to be allocated, and establishes a communication interface, such as an Xn interface, with the base station corresponding to the neighbor cell, and performs resource configuration interaction through the Xn interface. However, under the IAB network architecture shown in fig. 3, if in a mobile IAB scenario, for example, a scenario in which an IAB node serves a UE in a vehicle such as a subway, a bus, or a private car is deployed, other IAB nodes (e.g., a multi-hop relay scenario, a one-hop relay scenario) may exist between the mobile IAB node and the base station 1. Before a mobile IAB (e.g., an IAB node in fig. 3) moves to that location, no neighbor cells exist within the control range of an IAB hosting base station (e.g., an IAB hosting base station (base station 1) in fig. 3) and a base station 2 (e.g., base station 2 in fig. 3); when the mobile IAB moves to this position, a partial overlap area is generated between the cell under the mobile IAB node and the cell under the base station 2. Since there is no physical connection between the base station 1 and the base station 2, and no communication interface exists, at this time, a resource conflict may occur between a cell under the mobile IAB and a cell under the control of the base station 2.

The application provides a communication method, which is used for carrying out resource configuration interaction under a mobile IAB scene so as to avoid resource conflict.

Fig. 4 is a schematic diagram of a communication method 400 according to an embodiment of the present application. The method 400 may include the following steps.

S410, the first network device determines that the first cell is a missed neighbor of the second cell.

Specifically, the first network device adopts an ANR technology, and determines that the first cell is a missed neighbor cell of the second cell through the assistance of the terminal device.

The first cell is a cell managed by the second network device, and the second cell is a cell managed by the first network device, that is, the first network device and the second network device respectively manage two different cells.

The first cell is a missed neighbor cell of the second cell, which is understood that no neighbor cell relationship is configured between the first cell and the second cell, that is, resource configuration cannot be performed between the first network device managing the first cell and the second network device managing the second cell.

Wherein the first interface cannot be established between the second network device and the first network device.

It should be understood that the first interface is an interface for direct communication between network devices, such as an Xn interface, which is not limited by the present application.

For example, the inability to establish the first interface between the second network device and the first network device may be that there is no link connection between the second network device and the first network device.

The inability to establish the first interface between the second network device and the first network device may also be that a link connection exists between the second network device and the first network device, but the first interface is not allowed to be established due to network planning or the like.

It should be noted that the above-mentioned cases that the first interface cannot be established between the two second network devices and the first network device are merely examples, and the present application is not limited thereto.

The specific procedure of the first network device determining that the first cell is the missed neighbor of the second cell is as follows:

and the terminal equipment in the second cell performs neighbor cell measurement and sends a measurement report to the first network equipment, wherein the measurement report comprises PCI information of the neighbor cell. If the first network device determines that the neighbor cell is not maintained in the neighbor cell list of the first network device according to the PCI information of the neighbor cell, the first network device determines that the neighbor cell is a missed-configuration neighbor cell.

It should be noted that, the foregoing merely illustrates how the first network device determines the missed neighbor cell, and the scope of protection of the present application is not limited in any way, and in the embodiment of the present application, the specific principle of how the first network device determines the missed neighbor cell is not limited, and reference may be made to the related description of determining the missed neighbor cell by using the ANR technology.

The transmission direction of the timeslot resources is the uplink and downlink direction of each timeslot, and the transmission direction of the timeslot resources may include three directions of downlink (D), uplink (U), and flexible (F).

The time slot resource transmission state is a state of an IAB-DU in a transmission direction of the time slot, and may include a hard resource (hard, H), a soft resource (S), and an unavailable resource (NA).

Where H denotes the direction of transmission of resources that the DU needs to strictly adhere to the slot configuration.

S represents that DU is required to obey the constraint of the resource multiplexing mode between the node MT and the node MT, if the resource transmission direction of the time slot configured to DU is not in conflict with the resource direction of the parent node MT, the node MT works according to the configured resource transmission direction, otherwise, the resource transmission direction of the DU is required to be determined according to the resource transmission direction of the node MT.

NA indicates that the slot IAB-DU is not available.

The multiplexing manner of MT and DU resources of the IAB node is used to indicate the supporting situation of the IAB-DU and the MT part of the same IAB node for simultaneous transceiving when the first cell is generated by the IAB-DU, which includes but is not limited to the following cases: MT transmission simultaneous DU reception is supported/unsupported, MT transmission simultaneous DU transmission is supported/unsupported, MT reception simultaneous DU reception is supported/unsupported, MT reception simultaneous DU transmission is supported/unsupported.

Wherein the SSB transmission configuration of the sub-IAB-DUs is used to indicate the SSB configuration of a cell generated by the DU part of a certain IAB-MT belonging to the same IAB node when the serving cell of the certain IAB-MT is the first cell.

The SIB message is used for notifying the system information of the base station to the terminal equipment, and comprises an SIB1 message-SIB 21 message.

The SIB1 message includes scheduling conditions of other system message blocks and information required for initial access to the network, and the SIB1 message is also commonly called residual minimum system information (remaining minimum system information, RMSI), and is carried on a physical downlink shared channel (physical downlink shared channel, PDSCH), and may be periodically broadcast, or may be notified to the terminal device in a dedicated manner in a radio resource control (radio resource control, RRC) connected state. It should be noted that, before the terminal device receives the SIB2 message-SIB 21 message, the SIB1 message needs to be parsed first.

Alternatively, the first resource configuration information may be carried in SIB1 message of the first cell, or may be carried in another SIB message (for example, SIB2 message—sib21 message), which is not limited by the present application.

Based on the scheme, when no interface for direct communication exists between two base stations, after the local cell gNB acquires the NCGI of the missed-allocation neighbor cell through the ANR mechanism, the gNB corresponding to the missed-allocation neighbor cell performs two-hop flooding through the Xn interface to try to interact resource configuration information so as to achieve the effect of resource negotiation and avoid neighbor cell resource configuration conflict possibly caused by introducing a mobile IAB node. According to the scheme, the target base station is searched in the two-hop range of Xn interface communication, so that the target base station can be quickly found, and the resource allocation is interacted.
