Technical Field

[0001] This application relates to the field of communication technology, and more specifically, to a resource coordination method, apparatus, and system. Background Technology

[0002] The 3GPP 5G system introduces the WAB (Wireless Access and Backhaul) service. WAB uses the entire 5G base station (gNB) as a mobile L3 relay, employing single-hop backhaul with the Uu interface for the backhaul link. Through WAB technology, 5G access can be provided to UEs (User Equipment) on aircraft, cruise ships, helicopters, and vehicles in remote areas with limited visibility.

[0003] However, the current WAB resource configuration method directly adopts the one-way transmission mode of the Uu interface, which may cause conflicts and interference between the access link and the backhaul link, resulting in low communication efficiency. Summary of the Invention

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] First, let me introduce and explain some of the terms used in this application: WAB, Wireless Access and Backhaul; MT, Mobile Terminal; BH, Backhaul; RRC, Radio Resource Control; XnAP, Xn Application Protocol; AMF, Access and Mobility Management Function; DCI, Downlink Control Information.

[0040] The architecture of WAB is as follows Figure 1 As shown, the WAB node consists of two parts: WAB-gNB and WAB-MT. WAB-gNB provides access services to UE (User Equipment) through the Uu interface. WAB-MT connects to the BH-RAN node through the Uu interface to establish a radio backhaul link and provide a data backhaul channel for WAB-gNB.

[0041] Because the WAB node maintains communication connections with both the UE and the BH-RAN node simultaneously, radio transmissions on the access link (between the WAB-gNB and the UE) and the backhaul link (between the WAB-MT and the BH-RAN node) may interfere with each other. However, current WAB technology does not define a resource coordination process, leading to conflicts between WAB-MT scheduling and WAB-gNB UE service scheduling, and unavoidable interference between the access link and the backhaul link, resulting in low communication efficiency.

[0042] To address the above situation, this application proposes a resource coordination scheme. The technical solution of this application and its technical effects are explained below through the description of several exemplary embodiments. It should be noted that the following embodiments can be referenced, borrowed from, or combined with each other. Identical terms, similar features, and similar implementation steps in different embodiments will not be repeated.

[0043] One embodiment of this application provides a resource coordination method, which is executed by a first node. The first node can be a physical communication node or a virtual communication node, and this embodiment of the application does not limit it.

[0044] Figure 2 This is a flowchart illustrating the resource coordination method provided in an embodiment of this application, applied to the first node, such as... Figure 2 As shown, the method includes: Step S210: Send a first signaling message to the second node. The first signaling message carries first resource configuration information including the availability status of resource symbols of the cell served by the first node, so as to enable the second node to coordinate resources with the first node based on the availability status of resource symbols of the cell served by the first node.

[0045] Step S220: In response to receiving the second signaling sent by the second node, obtain the availability status of the resource symbols of the cell served by the second node in the second signaling, and coordinate resources with the second node based on the availability status of the resource symbols of the cell served by the second node. The second resource configuration information carried in the second signaling includes the availability status of the resource symbols of the cell served by the second node.

[0046] Specifically, the first node sends signaling or signaling information carrying resource configuration information to the second node, thereby establishing a connection between them to facilitate subsequent resource coordination. The resource configuration information includes the availability status of resource symbols for the cells served by the first node. Essentially, the first node informs the second node of the availability status of resource symbols for the cells it serves via signaling. Once the second node knows the availability status of the resource symbols for the cells served by the first node, it can easily coordinate resources with the first node based on this status. For example, the second node can decide whether to use, wait to use, or not use certain symbol resources based on the availability status of the resource symbols for the cells served by the first node.

[0047] After receiving the signaling from the first node, the second node sends a response message in response, signifying a successful handshake between them. This response message can be sent in the form of signaling, such as sending a second signaling message to the first node, which carries this response message. This response message (i.e., the second signaling message) carries second resource configuration information, which contains information about the second node's resources, such as information about the cells it serves (e.g., the availability status of resource symbols, the number of cells, etc.), to facilitate effective resource coordination with the first node during subsequent normal communication.

[0048] Through the above process, the first node not only knows its own resource configuration information, but also the resource configuration information of the second node. Similarly, the second node not only knows its own resource configuration information, but also the resource configuration information of the first node. This enables the mutual communication or exchange of resource information between the two nodes, facilitating precise resource coordination and configuration between them in the future.

[0049] The method provided in this application allows a first node and a second node to exchange resource configuration information via signaling. This enables them to coordinate and reuse resources based on the configuration information, thereby avoiding potential conflicts and interference, ensuring service quality, and improving communication efficiency. The resource configuration information carries the availability status of the cell's resource symbols, allowing for more precise control and management of wireless resources. This not only makes network planning and optimization more intuitive and simple but also enables precise resource coordination and configuration between the first and second nodes.

[0050] In one possible implementation of this application embodiment, the first node is a Node Radio Access Backhaul (WAB) node, and the second node is a Backhaul (BH-RAN) node. For example... Figure 1 As shown, the first node can be a WAB node and the second node can be a BH-RAN node, so that the WAB node and the BH-RAN node can directly perform resource configuration interaction and coordination processes.

[0051] The WAB node consists of two parts: WAB-gNB and WAB-MT. WAB-gNB provides access services to the UE via the Uu interface. WAB-MT connects to the BH-RAN node via the Uu interface, establishing a radio backhaul link and providing a data backhaul channel for WAB-gNB. WAB-gNB utilizes radio resources shared with BH-RAN (e.g., via the NR Uu interface) to carry backhaul traffic.

[0052] When a standard Xn interface is not established between the WAB node and the BH-RAN node, they can use RRC signaling on the Uu interface to complete resource coordination. That is, both the first and second signaling are RRC signaling. The WAB node and the BH-RAN node use RRC signaling to carry the first and second resource configuration information.

[0053] When a standard Xn interface has been established between the WAB node and the BH-RAN node, they can directly use Xn signaling to complete resource coordination. That is, both the first and second signaling are Xn signaling, and the WAB node and the BH-RAN node use Xn signaling to carry the first and second resource configuration information.

[0054] In one possible implementation of this application embodiment, the available state of a resource symbol includes at least one of a first state, a second state, or a third state; wherein, the first state is a symbol state that can be used directly; the second state is a symbol state that can be used conditionally depending on whether it has an impact on the first node; and the third state is a symbol state that cannot be used except for the available symbol time period of a preset scenario.

[0055] In one implementation, before each resource coordination with the BH-RAN node—that is, before the first node sends RRC signaling or Xn signaling carrying resource configuration information to the second node—the WAB node (e.g., WAB-gNB) can configure the availability status of resource symbols for the cell it serves. This configuration involves setting the availability status of resource symbols for the cell. The availability status of resource symbols can be threefold: a symbol state that can be used directly (i.e., the first state), a symbol state that can be used conditionally depending on whether it affects the first node (i.e., the second state), and a symbol state that cannot be used except during a preset available symbol time period (e.g., certain specific situations) (i.e., the third state). In other words, the first state indicates symbols that can be transmitted or received, the second state indicates symbols that can be scheduled under specific conditions, and the third state indicates symbols that cannot be scheduled except in special circumstances.

[0056] In one example, the first state described above can be denoted as "hard," the second state as "soft," and the third state as "unavailable." Symbols configured as "hard" can directly transmit or receive. Symbols configured as "unavailable" cannot be scheduled, except in some special cases. Symbols configured as "soft" can be conditionally scheduled if the BH-RAN node explicitly indicates availability via DCI, or conditionally debugged if the WAB node implicitly determines availability. The implicit determination of availability is made by the WAB node, depending on whether the operation of the WAB-gNB affects the co-located WAB-MT.

[0057] By categorizing cell resource symbols into three states—"hard," "soft," and "unavailable"—WAB nodes can more finely control and manage radio resources. The "hard" and "unavailable" states help clarify which symbol time periods are reserved for specific purposes or are completely unavailable, thereby reducing or avoiding potential interference. This is crucial for maintaining network performance and user experience. The introduction of "soft" states allows WAB nodes to dynamically adjust resource availability based on actual conditions (such as DCI indications from BH-RAN nodes or implicit assessments of the impact on WAB-gNB operations). This flexibility enables the network to adapt to different service demands and traffic patterns. Furthermore, with explicit symbol configuration, network planning and optimization become more intuitive and simpler, allowing network operators to more easily adjust and optimize resource allocation based on actual service needs and network performance indicators.

[0058] In one possible implementation of this application embodiment, the first resource configuration information further includes at least one of the following: The list of cells served by the WAB node, the number of cells served by the WAB node, the time slot format of the cells served by the WAB node on the corresponding link, whether the WAB node supports simultaneous reception of indication information by WAB-gNB and WAB-MT, whether the WAB node supports simultaneous transmission of indication information by WAB-gNB and WAB-MT, whether the WAB node supports simultaneous transmission of indication information by WAB-gNB and reception by WAB-MT, and whether the WAB node supports simultaneous reception of indication information by WAB-gNB and transmission by WAB-MT.

[0059] In one possible implementation of this application embodiment, the second resource configuration information includes at least one of the following: The list of cells served by the BH-RAN node, the number of cells served by the BH-RAN node, and the availability status of the time slot format and / or resource symbols of the cells served by the BH-RAN node on the corresponding links.

[0060] In one example, after the WAB-gNB establishes an NG interface with the UE's AMF, if resource configuration and coordination are required between the WAB node and the BH-RAN node, and an Xn connection has not yet been established between the WAB node and the BH-RAN node, then the BH-RAN node uses an NR Uu connection to transmit RRC signaling with the WAB node to complete the resource coordination. The resource coordination process initiated by the WAB node through RRC signaling can be as follows: Step 1: The WAB node configures resources for the cells served by WAB-gNB. The WAB node assigns three symbol states—hard, soft, and unavailable—to each resource symbol of each cell served by WAB-gNB.

[0061] Step 2: Xn Connection Detection. The WAB node checks whether there is an Xn connection between the WAB-MT and the BH-RAN node. In this example, the WAB node finds that there is no Xn connection between them.

[0062] Step 3: The WAB node initiates resource configuration sharing. The WAB node exchanges resource configuration information with the BH-RAN node by sending RRC signaling to coordinate resources. The RRC signaling includes (i.e. carries) the following IEs (i.e., first resource configuration information): the list of cells served by the WAB node, the number of cells served by the WAB node, the cell information of the cells served by the WAB node, gNB_RX / MT_RX, gNB_TX / MT_TX, gNB_TX / MT_RX, gNB_RX / MT_TX. Among them, the list of cells served by the WAB node refers to the list of cells served by the WAB-gNB of the WAB node. The number of cells served by the WAB node is the same as the number of cells served by the WAB-gNB. The cell information of the cells served by the WAB node includes the time slot format of each cell on the corresponding link and / or the type of each resource symbol (i.e., the availability status of the resource symbols mentioned above). gNB_RX / MT_RX indicates whether the WAB node supports simultaneous reception of WAB-gNB and WAB-MT. gNB_TX / MT_TX indicates whether the WAB node supports simultaneous transmission of WAB-gNB and WAB-MT. gNB_TX / MT_RX indicates whether the WAB node supports simultaneous transmission on WAB-gNB and reception on WAB-MT. gNB_RX / MT_TX indicates whether the WAB node supports simultaneous reception on WAB-gNB and transmission on WAB-MT.

[0063] Step 4: BH-RAN nodes share resource configuration information. After receiving the RRC signaling from the WAB node, the BH-RAN node sends a corresponding RRC signaling to the WAB node. This RRC signaling includes the following IEs (i.e., the second resource configuration information): the BH-RAN node cell list, the number of BH-RAN node cells, and the BH-RAN node cell information. The BH-RAN node cell list refers to the list of cells served by the BH-RAN node; the number of BH-RAN node cells is the number of cells served by the BH-RAN node; and the BH-RAN node cell information includes the time slot format and / or the type of each symbol (i.e., the availability status of the aforementioned resource symbols) for each cell on the corresponding link.

[0064] In another example, after the WAB-gNB establishes an NG interface with the UE's AMF, if resource configuration and coordination are required between the WAB node and the BH-RAN node, and an Xn connection has already been established between the WAB node and the BH-RAN node, then the BH-RAN node uses the Xn connection to transmit Xn signaling with the WAB node to complete the resource coordination. The resource coordination process initiated by the WAB node through Xn signaling can be as follows: Step 1: The WAB node configures resources for the cells served by WAB-gNB. The WAB node assigns three symbol states—hard, soft, and unavailable—to each resource symbol of each cell served by WAB-gNB.

[0065] Step 2: Xn Connection Detection. The WAB node detects whether there is an Xn connection between the WAB-MT and the BH-RAN node. In this example, the WAB node detects an Xn connection between them.

[0066] Step 3: The WAB node initiates resource configuration sharing. The WAB node exchanges resource configuration information with the BH-RAN node by sending Xn signaling to coordinate resources. The Xn signaling contains (i.e. carries) the following IE (i.e., first resource configuration information): the list of cells served by the WAB node, the number of cells served by the WAB node, the cell information of the cells served by the WAB node, gNB_RX / MT_RX, gNB_TX / MT_TX, gNB_TX / MT_RX, gNB_RX / MT_TX. Among them, the list of cells served by the WAB node refers to the list of cells served by the WAB-gNB of the WAB node. The number of cells served by the WAB node is the same as the number of cells served by the WAB-gNB. The cell information of the cells served by the WAB node includes the time slot format of each cell on the corresponding link and / or the type of each resource symbol (i.e., the availability status of the resource symbols mentioned above). gNB_RX / MT_RX indicates whether the WAB node supports simultaneous reception of WAB-gNB and WAB-MT. gNB_TX / MT_TX indicates whether the WAB node supports simultaneous transmission of WAB-gNB and WAB-MT. gNB_TX / MT_RX indicates whether the WAB node supports simultaneous transmission on WAB-gNB and reception on WAB-MT. gNB_RX / MT_TX indicates whether the WAB node supports simultaneous reception on WAB-gNB and transmission on WAB-MT.

[0067] Step 4: BH-RAN nodes share resource configuration information. After receiving the RRC signaling from the WAB node, the BH-RAN node sends a corresponding Xn signaling to the WAB node. This Xn signaling contains the following IEs (i.e., the second resource configuration information): the BH-RAN node cell list, the number of BH-RAN node cells, and the BH-RAN node cell information. The BH-RAN node cell list refers to the list of cells served by the BH-RAN node; the number of BH-RAN node cells is the number of cells served by the BH-RAN node; and the BH-RAN node cell information includes the time slot format and / or the type of each symbol (i.e., the availability status of the aforementioned resource symbols) for each cell on the corresponding link.

[0068] According to another aspect of the embodiments of this application, a resource coordination method is provided, executed by a second node, such as... Figure 3 As shown, the method includes: Step S310: Receive first signaling sent by the first node, the first signaling carrying first resource configuration information including the availability status of resource symbols of the cell served by the first node; Step S320: In response to the first signaling, send a second signaling to the first node, the second signaling carrying second resource configuration information including the availability status of resource symbols of the cell served by the first node; Step S330: Coordinate resources with the first node based on the availability status of resource symbols of the cell served by the first node.

[0069] Specifically, the second node sends signaling or signaling information carrying resource configuration information to the first node to establish a connection, enabling subsequent resource coordination between the two. This resource configuration information contains information about the second node's resources, such as information about the cells served by the second node (e.g., the availability status of resource symbols, the number of cells, etc.), to facilitate effective resource coordination with the first node during normal communication.

[0070] After receiving signaling from the second node, the first node sends a response message in reply, signifying a successful handshake between them. This response message can be sent in the form of signaling, such as sending a first signaling message to the second node, which carries this response message. This response message (the first signaling message) carries first resource configuration information, which includes the availability status of resource symbols for the cell served by the first node. Essentially, the first node informs the second node of the availability status of the resource symbols for the cell it serves via signaling. Knowing the availability status of the resource symbols for the cell served by the first node, the second node can easily coordinate resources with the first node based on this information. For example, the second node can decide whether to use, wait to use, or not use certain resource symbols based on their availability.

[0071] Through the above process, the second node not only knows its own resource configuration information, but also the resource configuration information of the first node. Similarly, the first node not only knows its own resource configuration information, but also the resource configuration information of the second node. This enables the mutual communication or exchange of resource information between the two nodes, facilitating precise resource coordination and configuration between them in the future.

[0072] The method provided in this application allows a first node and a second node to exchange resource configuration information via signaling. This enables them to coordinate and reuse resources based on the configuration information, thereby avoiding potential conflicts and interference, ensuring service quality, and improving communication efficiency. The resource configuration information carries the availability status of the cell's resource symbols, allowing for more precise control and management of wireless resources. This not only makes network planning and optimization more intuitive and simple but also enables precise resource coordination and configuration between the first and second nodes.

[0073] In one possible implementation of this application embodiment, the first node is a Node Radio Access Backhaul (WAB) node, and the second node is a Backhaul (BH-RAN) node.

[0074] In one possible implementation of this application, when there is no Xn connection between the second node and the first node, both the second signaling and the first signaling are RRC signaling; when there is an Xn connection between the second node and the first node, both the second signaling and the first signaling are Xn signaling.

[0075] In one possible implementation of this application embodiment, the available state of a resource symbol includes at least one of a first state, a second state, or a third state; wherein, the first state is a symbol state that can be used directly; the second state is a symbol state that can be used conditionally depending on whether it has an impact on the first node; and the third state is a symbol state that cannot be used except for the available symbol time period of a preset scenario.

[0076] In one possible implementation of this application embodiment, the first resource configuration information further includes at least one of the following: The list of cells served by the WAB node, the number of cells served by the WAB node, the time slot format of the cells served by the WAB node on the corresponding link, whether the WAB node supports simultaneous reception of indication information by WAB-gNB and WAB-MT, whether the WAB node supports simultaneous transmission of indication information by WAB-gNB and WAB-MT, whether the WAB node supports simultaneous transmission of indication information by WAB-gNB and reception by WAB-MT, and whether the WAB node supports simultaneous reception of indication information by WAB-gNB and transmission by WAB-MT.

[0077] In one possible implementation of this application, the second resource configuration information includes at least one of the following: a list of cells served by the BH-RAN node, the number of cells served by the BH-RAN node, and the availability status of the time slot format and / or resource symbols of the cells served by the BH-RAN node on the corresponding links.

[0078] In one example, after the WAB-gNB establishes an NG interface with the UE's AMF, if resource configuration and coordination are required between the WAB node and the BH-RAN node, and an Xn connection has not yet been established between the WAB node and the BH-RAN node, then the BH-RAN node uses an NR Uu connection to transmit RRC signaling with the WAB node to complete the resource coordination. The resource coordination process initiated by the BH-RAN node through RRC signaling can be as follows: Step 1: The WAB node configures resources for the cells served by WAB-gNB. The WAB node assigns three symbol states—hard, soft, and unavailable—to each resource symbol of each cell served by WAB-gNB.

[0079] Step 2: Xn Connection Detection. The BH-RAN node checks whether there is an Xn connection between the BH-RAN node and the WAB node. In this example, the BH-RAN node finds that there is no Xn connection between them.

[0080] Step 3: The BH-RAN node initiates resource configuration sharing. The BH-RAN node sends RRC signaling to the WAB node to exchange resource configuration information for resource coordination. The RRC signaling includes the following IEs (i.e., the second resource configuration information): the BH-RAN node cell list, the number of BH-RAN node cells, and BH-RAN node cell information. The BH-RAN node cell list refers to the list of cells served by the BH-RAN node. The number of BH-RAN node cells is the number of cells served by the BH-RAN node, and the BH-RAN node cell information includes the time slot format of each cell on the corresponding link and / or the type of each resource symbol (i.e., the availability status of the aforementioned resource symbols).

[0081] Step 4: WAB Nodes Share Resource Configuration Information. After receiving the RRC signaling from the BH-RAN node, the WAB node sends a corresponding RRC signaling to the BH-RAN node. This RRC signaling includes the following IEs (i.e., the first resource configuration information): the list of cells served by the WAB node, the number of cells served by the WAB node, the cell information of the cells served by the WAB node, gNB_RX / MT_RX, gNB_TX / MT_TX, gNB_TX / MT_RX, gNB_RX / MT_TX. The list of cells served by the WAB node refers to the list of cells served by the WAB-gNB node. The number of cells served by the WAB node is the same as the number of cells served by the WAB-gNB. The cell information of the cells served by the WAB node includes the time slot format of each cell on the corresponding link and / or the type of each resource symbol (i.e., the availability status of the resource symbols mentioned above). gNB_RX / MT_RX indicates whether the WAB node supports simultaneous reception of WAB-gNB and WAB-MT. gNB_TX / MT_TX indicates whether the WAB node supports simultaneous transmission of WAB-gNB and WAB-MT. gNB_TX / MT_RX indicates whether the WAB node supports simultaneous transmission on WAB-gNB and reception on WAB-MT. gNB_RX / MT_TX indicates whether the WAB node supports simultaneous reception on WAB-gNB and transmission on WAB-MT.

[0082] In another example, after the WAB-gNB and the UE's AMF establish an NG interface, if resource configuration and coordination are required between the WAB node and the BH-RAN node, and an Xn connection has already been established between the WAB node and the BH-RAN node, then the BH-RAN node uses the Xn connection to transmit Xn signaling with the WAB node to complete the resource coordination. The resource coordination process initiated by the BH-RAN node through Xn signaling can be as follows: Step 1: The WAB node configures resources for the cells served by WAB-gNB. The WAB node assigns three symbol states—hard, soft, and unavailable—to each resource symbol of each cell served by WAB-gNB.

[0083] Step 2: Xn Connection Detection. The BH-RAN node detects whether there is an Xn connection between the BH-RAN node and the WAB node. In this example, the BH-RAN node detects an Xn connection between the two.

[0084] Step 3: The BH-RAN node initiates resource configuration sharing. The BH-RAN node sends Xn signaling to the WAB node to exchange resource configuration information for resource coordination. The Xn signaling includes the following IEs (i.e., the first resource configuration information): the BH-RAN node cell list, the number of BH-RAN node cells, and BH-RAN node cell information. The BH-RAN node cell list refers to the list of cells served by the BH-RAN node. The number of BH-RAN node cells is the number of cells served by the BH-RAN node, and the BH-RAN node cell information includes the time slot format of each cell on the corresponding link and / or the type of each resource symbol (i.e., the availability status of the aforementioned resource symbols).

[0085] Step 4: WAB Nodes Share Resource Configuration Information. After receiving the Xn signaling from the BH-RAN node, the WAB node sends a corresponding Xn signaling to the BH-RAN node. This Xn signaling includes the following IEs (i.e., the first resource configuration information): the list of cells served by the WAB node, the number of cells served by the WAB node, the cell information of the cells served by the WAB node, gNB_RX / MT_RX, gNB_TX / MT_TX, gNB_TX / MT_RX, gNB_RX / MT_TX. The list of cells served by the WAB node refers to the list of cells served by the WAB-gNB node. The number of cells served by the WAB node is the same as the number of cells served by the WAB-gNB. The cell information of the cells served by the WAB node includes the time slot format of each cell on the corresponding link and / or the type of each resource symbol (i.e., the availability status of the resource symbols mentioned above). gNB_RX / MT_RX indicates whether the WAB node supports simultaneous reception of WAB-gNB and WAB-MT. gNB_TX / MT_TX indicates whether the WAB node supports simultaneous transmission of WAB-gNB and WAB-MT. gNB_TX / MT_RX indicates whether the WAB node supports simultaneous transmission on WAB-gNB and reception on WAB-MT. gNB_RX / MT_TX indicates whether the WAB node supports simultaneous reception on WAB-gNB and transmission on WAB-MT.

[0086] In this embodiment, the WAB node or BH-RAN node can notify each other via RRC signaling or Xn signaling over the NR Uu connection to exchange semi-static radio resource configurations between the WAB node and the BH-RAN node, thereby completing resource coordination and resource reuse functions.

[0087] This application primarily addresses the issue of resource coordination between WAB nodes and BH-RAN nodes when an Xn connection is established or not. The WAB node uses RRC / Xn signaling to coordinate resources and exchange resource configuration information, thereby avoiding interference between access and backhaul links and ensuring service quality. This application proposes a resource coordination process scheme for WAB technology network architecture to avoid interference between access and backhaul links and ensure service quality.

[0088] This application provides a resource coordination device applied to a first node, such as... Figure 4 As shown, the device 400 may include: a first transmitting module 401, a first receiving module 402, and a first coordinating module 403, wherein, The first sending module 401 is configured to send a first signaling to the second node. The first signaling carries first resource configuration information including the availability status of resource symbols of the cell served by the first node, so that the second node can perform resource coordination with the first node based on the availability status of resource symbols of the cell served by the first node. The first receiving module 402 is configured to, in response to receiving the second signaling sent by the second node, obtain the availability status of the resource symbols of the cell served by the second node in the second signaling, wherein the second resource configuration information carried in the second signaling includes the availability status of the resource symbols of the cell served by the second node. The first coordination module 403 is used to coordinate resources with the second node based on the availability status of resource symbols of the cell served by the second node.

[0089] In this embodiment, the first node and the second node exchange resource configuration information via signaling. This enables them to coordinate and reuse resources based on the configuration information, thereby avoiding potential conflicts and interference, ensuring service quality, and improving communication efficiency. The resource configuration information carries the availability status of the cell's resource symbols, allowing for more precise control and management of wireless resources. This not only makes network planning and optimization more intuitive and simple but also enables precise resource coordination and configuration between the first and second nodes.

[0090] In one possible implementation of this application embodiment, when there is no Xn connection between the first node and the second node, both the first signaling and the second signaling are RRC signaling; When there is an Xn connection between the first node and the second node, both the first signaling and the second signaling are Xn signaling.
