[0002] The 5G system introduces Wireless Access and Backhaul (WAB) services. WAB services are flexible and allow for dense deployment of NR cells, while reducing the need for wired transmission infrastructure.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0163] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0164] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0165] This application provides a resource coordination method and apparatus. The WAB node and the BH-RAN node exchange radio resource configurations to complete resource coordination and resource reuse, thereby reducing interference and improving communication efficiency.

Where there is no conflict between the embodiments, the following embodiments and features can be combined with each other. Furthermore, the timing of the steps in the following method embodiments is merely an example and not a strict limitation.

[0168] See Figure 1 As shown, Figure 1 This is a flowchart illustrating the resource coordination method provided in this embodiment. The execution entity of the resource coordination method provided in this embodiment is a WAB node, and the resource coordination method will be described in detail below.

[0169] The resource coordination method provided in this application includes the following steps:

[0170] Step 101: Send first radio resource configuration information to the backhaul-radio access network (BH-RAN) node. The first radio resource configuration information is used to indicate the time slot format of the radio access backhaul-base station (WAB-gNB) cell of the WAB node and / or the symbol type of the symbol of the WAB-gNB cell.

[0171] Step 102: Receive the second radio resource configuration information sent by the BH-RAN node. The second radio resource configuration information is used to indicate the time slot format of the BH-RAN node cell.

[0172] In this embodiment, the wireless resource configuration between the WAB node and the BH-RAN node is exchanged to achieve resource coordination and resource reuse, thereby reducing interference and improving communication efficiency.

Figure 2The BH-RAN node in the WAB-gNB can also be other surrounding NG-RAN nodes. Operations, Administration, and Maintenance (OAM) services of the WAB-gNB can also be transmitted through BH Protocol Data Unit (PDU) sessions.

[0174] A WAB node can include Next Generation NodeB (gNB) equipment (e.g., Wireless Access and Backhaul-gNB, WAB-gNB) and Mobile Terminal (MT) equipment (e.g., Wireless Access and Backhaul-Mobile Terminal, WAB-MT). Both WAB-gNB and WAB-MT can be deployed on a WAB node; in (future) communication networks, they can also be deployed independently as separate nodes, without specific limitations. A BH-RAN node refers to an NG-RAN node serving a WAB-MT.

[0175] WAB-gNB has gNB functionality based on the standard.

[0176] We do not consider separating WAB-gNB into Centralized Units (CUs) and Distributed Units (DUs).

[0177] WAB-MT supports some UE functions.

[0178] Uu (including but not limited to NR Uu) is used for the radio link between WAB-gNB and servicing UE, as well as the radio link between WAB-MT and BH-RAN nodes.

[0179] WAB-gNB services are transmitted via PDU session backhaul.

[0180] The Uu (including but not limited to NR Uu) radio link between WAB-gNB and UE does not use NTN.

[0181] WAB-gNB cannot serve WAB-MT (it should be noted that in existing or future communication systems, there is no specific limitation on whether WAB-gNB serves WAB-MT; it may or may not).

[0182] WAB-MT can connect to a Public Land Mobile Network (PLMN) or a Stand-alone Non-Public Network (SNPN).

[0183] The WAB-gNB can be connected to a public PLMN or SNPN.

[0184] WAB-gNB and WAB-MT can be connected to the same PLMN or different PLMNs.

[0185] Traditional UEs can also connect to WAB-gNB.

[0186] A BH-RAN node refers to an NG-RAN node that serves WAB-MT.

[0187] BH-gNB refers to the gNB that serves WAB-MT.

[0188] BH-AMF refers to the AMF that serves WAB-MT.

[0195] It should be noted that the NR Uu link in Figure 2 is exemplary, and the Uu link is not limited to the NR Uu link here.

[0196] The radio resource configuration of the WAB node is the first radio resource configuration information, which indicates the WAB node cell information. This WAB node cell information includes at least one of the following: the timeslot format of the WAB-gNB cell of the WAB node, and the symbol type of the WAB-gNB cell symbol. Here, the WAB-gNB cell refers to the cell served by the WAB-gNB; specifically, the WAB node cell is the cell of the WAB node used to serve UEs accessing its node. For example, a UE located in the WAB node cell can access the WAB node and receive services within the WAB node. The WAB node cell refers to the WAB-gNB cell, which will not be elaborated further below.

[0197] The radio resource configuration of a BH-RAN node is the second radio resource configuration information, which indicates the BH-RAN node cell information. This BH-RAN node cell information includes the time slot format of each BH-RAN node cell on the corresponding link. A BH-RAN node cell is a cell used by a BH-RAN node to serve nodes accessing it. For example, a WAB node is located in a BH-RAN node cell and accesses the BH-RAN node, receiving services within the BH-RAN node cell. A BH-RAN node cell refers to an NG-RAN node cell serving WAB-MT.

[0198] It should be noted that the order in which the WAB node sends its first radio resource configuration information to the BH-RAN node and the order in which the WAB node receives the second radio resource configuration information sent by the BH-RAN node is not limited, and the purpose is to achieve the exchange of resource configuration information.

[0199] In some embodiments, the time slot format includes at least one of the following:

[0200] The number of time slots used for uplink transmission and the location of the time slots used for uplink transmission;

[0201] The number of time slots used for downlink transmission and the location of the time slots used for downlink transmission;

[0202] The number of time slots containing flexible symbols and the location of time slots containing flexible symbols.

[0203] In some embodiments, the symbol type includes at least one of the following:

[0204] A first symbol type, which is used to indicate the symbol type used without affecting the WAB-MT of the WAB node;

[0205] A second symbol type, which is used to indicate an unavailable symbol type;

[0206] A third symbol type, which is used to indicate a symbol type that is allowed to be used conditionally.

[0207] In this embodiment of the application, combined with Figure 3 As shown, Figure 3 Interaction illustration of the resource coordination method provided in the embodiments of this application Figure 1 .

[0208] Step 301: The WAB node sends the first radio resource configuration information to the BH-RAN node, such as the time slot format of the WAB-gNB cell and / or the symbol type of the symbol of the WAB-gNB cell.

[0209] Step 302: The BH-RAN node sends the second radio resource configuration information to the WAB node, such as the time slot format of the BH-RAN node cell.

[0210] The time slot format includes, for example, one or more of the following: the number of time slots used for uplink transmission, the time slot positions used for uplink transmission, the number of time slots used for downlink transmission, the time slot positions used for downlink transmission, the number of time slots containing flexible symbols, and the time slot positions containing flexible symbols.

[0211] Symbol types are divided into three categories: the first category is "hard" symbols, which can be used without affecting WAB-MT; the second category is "unavailable" symbols, which cannot be used because they affect WAB-MT; and the third category is "soft" symbols, which can be used conditionally depending on whether they affect WAB-MT. The scheduling of WAB-gNB cells is consistent with the symbol type of each symbol.

[0212] In some embodiments, the first radio resource configuration information is further used to indicate the time slot format of the BH-RAN node cell proposed by the WAB node; and / or,

[0213] The first radio resource configuration information is also used to indicate at least one of the following: a list of WAB-gNB cells, the number of WAB-gNB cells, and the duplex capability of WAB nodes.

[0214] In this embodiment, the WAB node can also notify the BH-RAN node of its WAB-gNB cell list, the number of WAB-gNB cells, and the WAB node's duplex capability, thereby achieving resource coordination and exchange between the two nodes. The WAB node can also suggest to the BH-RAN node, through the first radio resource configuration information, that the BH-RAN node modify the time slot format of the BH-RAN node's cells, so that the BH-RAN node can configure the BH-RAN node's cells according to the time slot format suggested by the WAB node, thereby completing resource coordination and resource reuse, reducing interference, and improving communication efficiency.

[0215] For example, the WAB node suggests modifying the time slot format of the BH-RAN node cell to the BH-RAN node through the first radio resource configuration information. This can be achieved by the WAB node sending multiple candidate time slot formats to the BH-RAN node through the first radio resource configuration information, which the BH-RAN node can use to modify the time slot format of the BH-RAN node cell. Alternatively, the WAB node can indicate multiple candidate time slot formats to the BH-RAN node through the first radio resource configuration information. The BH-RAN node can choose to use one of the multiple candidate time slot formats to modify the time slot format of the BH-RAN node cell, or it can choose not to use one of the multiple candidate time slot formats to modify the time slot format of the BH-RAN node cell.

[0216] In some embodiments, the second radio resource configuration information is further used to indicate the time slot format of the WAB-gNB cell proposed by the BH-RAN node and / or the symbol type of the WAB-gNB cell symbol; and / or,

[0217] The second radio resource configuration information is also used to indicate the list of BH-RAN node cells and / or the number of BH-RAN node cells.

[0218] In this embodiment, the WAB node can also receive resource configurations such as the BH-RAN node cell list and / or the number of BH-RAN node cells notified by the BH-RAN node, thereby achieving resource coordination and exchange of resource configurations between the two nodes. The WAB node can also receive resource configurations such as the time slot format and / or the symbol type of the WAB-gNB cell suggested by the BH-RAN node. The WAB node can configure the WAB-gNB cell according to the time slot format and / or the symbol type of the WAB-gNB cell suggested by the BH-RAN node, thereby completing resource coordination and resource reuse, reducing interference, and improving communication efficiency.

[0219] For example, the BH-RAN node suggesting to the WAB node via the second radio resource configuration information to modify the time slot format and / or the symbol type of the WAB-gNB cell can be: the BH-RAN node sending to the WAB node via the second radio resource configuration information multiple candidate time slot formats that the WAB node can use to modify the time slot format of the WAB-gNB cell, and / or, the BH-RAN node sending to the WAB node via the second radio resource configuration information multiple candidate symbol types that the WAB node can use to modify the symbol type of the WAB-gNB cell; or: BH-R The AN node indicates multiple candidate time slot formats to the WAB node via the second radio resource configuration information, and / or the BH-RAN node indicates multiple candidate symbol types to the WAB node via the second radio resource configuration information. The WAB node may use the time slot format from the multiple candidate time slot formats to modify the time slot format of the WAB-gNB cell and / or the symbol type of the WAB-gNB cell's symbols, or it may not use the time slot format from the multiple candidate time slot formats to modify the time slot format of the WAB-gNB cell and / or not use the symbol types of the multiple candidate symbols to modify the symbol type of the WAB-gNB cell's symbols.

[0220] In this embodiment of the application, combined with Figure 4 As shown, Figure 4 Interaction illustration of the resource coordination method provided in the embodiments of this application Figure 2 .

[0221] Step 401: The WAB node sends the first radio resource configuration information to the BH-RAN node, such as the time slot format of the BH-RAN node cell suggested by the WAB node.

[0222] Step 402: The BH-RAN node sends the second radio resource configuration information to the WAB node, such as the time slot format of the WAB-gNB cell and / or the symbol type of the WAB-gNB cell suggested by the BH-RAN node.

[0223] The first radio resource configuration information may further include at least one of the following: a WAB-gNB cell list, the number of WAB-gNB cells, and the WAB node duplex capability. The WAB node cell list (here referring to WAB-gNB cells) refers to the list of cells served by the WAB node in the WAB-gNB service. The number of WAB node cells is the number of cells served by the WAB-gNB service. The WAB node cell information includes the time slot format of each WAB node cell (e.g., a WAB-gNB cell, which will not be elaborated further below) and / or the type of each symbol of each WAB node cell. The WAB node duplex capability includes the following information:

[0224] A WAB node supports simultaneous reception on both WAB-gNB and WAB-MT, or it may not support simultaneous reception on both WAB-gNB and WAB-MT. A WAB node supports simultaneous transmission on both WAB-gNB and WAB-MT, or it may not support simultaneous transmission on both WAB-gNB and WAB-MT. A WAB node supports simultaneous transmission on WAB-gNB and reception on WAB-MT, or it may not support simultaneous transmission on both WAB-gNB and WAB-MT. A WAB node supports simultaneous reception on WAB-gNB and transmission on WAB-MT, or it may not support simultaneous reception on WAB-gNB and transmission on WAB-MT.

[0225] The second radio resource configuration information may also include at least one of the following: a list of BH-RAN node cells and a number of BH-RAN node cells. The list of BH-RAN node cells 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.

[0226] In some embodiments, the first radio resource configuration information is carried by a radio resource control (RRC) signaling bearer or an Xn signaling bearer; and / or, the second radio resource configuration information is carried by an RRC signaling bearer or an Xn signaling bearer.

[0227] In this embodiment, both the first and second radio resource configuration information can be transmitted via Radio Resource Control (RRC) signaling or Xn signaling to coordinate and exchange resource configurations between the two nodes, thereby achieving the purpose of resource coordination. Specifically, during the resource coordination process, the uplink or downlink signaling can be any of the following: RRC signaling or Xn signaling.

[0228] In some embodiments, the connection between the WAB node and the BH-RAN node is such that there is an RRC connection but no Xn connection, or the connection between the WAB node and the BH-RAN node is such that there is an Xn connection.

[0229] In this embodiment, the WAB node and the BH-RAN node can transmit radio resource configuration via either an RRC connection or an Xn connection to achieve resource coordination. Specifically, during resource coordination, the connection between the WAB node and the (BH: backhaul) BH-RAN node falls into one of the following categories: an RRC connection exists but an Xn connection does not exist; or the connection between the WAB node and the BH-RAN node is an Xn connection.

[0230] In some embodiments, the method further includes:

[0231] Send first information to the BH-RAN node, the first information indicating at least one of the following: WAB-gNB identification information, WAB-MT identification information, cell identification information broadcast by WAB-gNB, Physical Cell Identifier (PCI), Tracking Area Code (TAC); or,

[0232] Send a second message to the BH-RAN node, the second message being used to indicate the WAB-MT identification information co-located with WAB-gNB or to indicate the WAB-gNB identification information co-located with WAB-MT.

[0233] The first piece of information can be sent in stages, with the BH-RAN node determining whether it is the WAB-gNB co-located with the WAB-MT, or the WAB-MT co-located with the WAB-gNB.

[0234] In this embodiment of the application, combined with Figure 5 As shown, Figure 5 Interaction illustration of the resource coordination method provided in the embodiments of this application Figure 3 .

[0235] Step 501: The WAB node sends the first information to the BH-RAN node, such as: WAB-gNB identification information (e.g., WAB-gNB identifier information element, abbreviated as IE)), WAB-MT identification information (e.g., WAB-MT identifier), cell identification information broadcast by WAB-gNB (e.g., cell ID), physical cell identifier (e.g., PCI), tracking area code (TAC), etc., at least one of the following.

[0236] Step 502: The BH-RAN node determines the WAB-MT or the WAB-gNB that is co-located with the WAB-gNB based on the first information.

[0237] Specifically, the information obtained when establishing a co-location relationship includes one or more of the following: the WAB-gNB identifier (IE) that uniquely identifies the WAB node, the WAB-MT identifier, the cell ID broadcast by the WAB-gNB, the physical cell identifier (PCI), TAC, and other information.

[0238] In this embodiment of the application, combined with Figure 6 As shown, Figure 6 Interaction illustration of the resource coordination method provided in the embodiments of this application Figure 4 .

[0239] Step 601: The WAB node sends a second piece of information to the BH-RAN node, such as the identification information of the WAB-MT that is co-located with the WAB-gNB or the identification information of the WAB-gNB that is co-located with the WAB-MT.

[0240] Step 602: The BH-RAN node determines the WAB-MT or the WAB-gNB that is co-located with the WAB-gNB based on the second information.

[0241] In some embodiments, the WAB-gNB identification information includes at least one of the following: the global base station identifier of the WAB-gNB, and the IP address of the WAB-gNB used to establish the Xn connection.

[0242] For example, the WAB-gNB identifier can be one or more of the following: the Global gNB-ID of the WAB-gNB, or the IP address used by the WAB-gNB to establish Xn.

[0243] In some embodiments, the WAB-MT identification information includes at least one of the following: cell identification information serving WAB-MT, and cell radio network temporary identifier (C-RNTI) assigned to WAB-MT.

[0244] For example, WAB-MT identification information can be one or more of the following: cell identity of the serving WAB-MT cell, and cell-radio network temporary identifier (C-RNTI) assigned to WAB-MT by the BH-RAN node when WAB-MT is established.

[0245] Among them, the cells serving WAB-MT refer to the cells under the BH-RAN node, such as BH-RAN node cells or cells served by the BH-RAN node.

[0246] In this embodiment of the application, the WAB node can also send first information or second information to the BH-RAN node, so that the BH-RAN node can determine the WAB-MT that co-addresses with the WAB-gNB in ​​the WAB node or determine the WAB-gNB that co-addresses with the WAB-MT, which facilitates subsequent communication, thereby realizing resource coordination and resource reuse, reducing interference and improving communication efficiency.

[0247] In some embodiments, the first information is sent by the WAB-MT via RRC signaling; and / or,

[0248] The second information is sent by the WAB-gNB via Xn signaling.

[0249] In the embodiments of this application, during the co-location discovery process, the uplink signaling or downlink signaling can be one or more of the following: RRC signaling, Xn signaling.

[0250] In some embodiments, the method further includes:

[0251] Configure the WAB-gNB cell according to the time slot format and / or symbol type of the WAB-gNB cell suggested by the BH-RAN node.

[0252] In this embodiment, the WAB node can configure the WAB-gNB cell according to the time slot format of the WAB-gNB cell and / or the symbol type of the WAB-gNB cell suggested by the BH-RAN node, thereby completing resource coordination and resource reuse, reducing interference and improving communication efficiency.

[0253] In this application, after the WAB integration process is completed, the WAB node or BH-RAN node can notify configuration information (e.g., radio resource configuration information) via RRC signaling on the RRC connection (e.g., when no Xn connection is established between the WAB-MT of the WAB node and the BH-RAN node). Alternatively, after the Xn connection is established, the BH-RAN node first obtains information via RRC signaling on the NG-RAN backhaul link (including the NR Uu link or the E-UTRA Uu link, where the NR Uu link refers to the link established between the UE and the 5G base station (e.g., gNodeB) through the Uu interface, and the E-UTRA Uu link refers to the link established between the UE and the evolved UMTS terrestrial radio access network (E-UTRAN)) and via Xn signaling on the Xn link, finds the WAB-gNB co-located with the WAB-MT, establishes a co-location relationship, and then notifies the configuration information via Xn signaling, exchanges radio resource configurations (e.g., semi-static radio resource configurations) between the WAB node and the BH-RAN node, and completes resource coordination and resource reuse functions.

[0254] For example, in Implementation Example 1: After a Next Generation (NG) interface is established between the WAB-gNB and the UE's AMF, if resource configuration and coordination are required, the BH-RAN node uses an RRC connection to transmit RRC signaling with the WAB-gNB (for example, when no Xn connection is established between the WAB-MT of the WAB node and the BH-RAN node) to complete the purpose of resource coordination; whereby the UE's AMF refers to the Access and Mobility Management Function (AMF) that connects to the WAB-gNB and provides services to the UE.

[0255] Resource coordination can be achieved through at least two of the following methods:

[0256] Method 1-1: The WAB node initiates RRC signaling to trigger the WAB resource coordination process.

[0257] Step 1: Resource Configuration. The WAB node determines the time slot format for each WAB-gNB cell and the symbol type for each symbol in each WAB-gNB cell. The time slot format includes the number and location of uplinks (referring to the number and location of time slots used for uplink transmission, which will not be elaborated further below), the number and location of downlinks (referring to the number and location of time slots used for downlink transmission, which will not be elaborated further below), and the number and location of flexible symbols (referring to the number and location of time slots containing flexible symbols). The symbol type includes three types: hard (referring to the first symbol type), soft (referring to the third symbol type), or unavailable (referring to the second symbol type). Symbols configured as hard can be transmitted or received. Symbols configured as unavailable cannot be scheduled except in some special cases. For symbols configured as soft, scheduling can occur conditionally if the BH-RAN node explicitly indicates availability via signaling (such as DCI format 2_5), or 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 will affect the co-located WAB-MT.

[0258] Step 2: This step is optional. The WAB node checks whether there is an Xn connection between the WAB-gNB and the BH-RAN node. If so, the WAB node finds that there is no Xn connection between them.

[0259] Step 3: The WAB node sends RRC signaling to the BH-RAN node to coordinate and exchange resource configurations between the two nodes. The RRC signaling includes the following information: WAB node cell list, number of WAB node cells, WAB node cell information, and WAB node duplex capability. The WAB node cell list refers to the list of cells served by the WAB node's WAB-gNB service. The number of WAB node cells is the number of cells served by the WAB-gNB service. The WAB node cell information includes the time slot format of each WAB node cell and / or the type of each symbol for each WAB node cell. The WAB node duplex capability includes the following information:

[0260] A WAB node supports simultaneous reception on both WAB-gNB and WAB-MT, or it may not support simultaneous reception on both WAB-gNB and WAB-MT. A WAB node supports simultaneous transmission on both WAB-gNB and WAB-MT, or it may not support simultaneous transmission on both WAB-gNB and WAB-MT. A WAB node supports simultaneous transmission on WAB-gNB and reception on WAB-MT, or it may not support simultaneous transmission on both WAB-gNB and WAB-MT. A WAB node supports simultaneous reception on WAB-gNB and transmission on WAB-MT, or it may not support simultaneous reception on WAB-gNB and transmission on WAB-MT.

[0261] In some embodiments, the WAB node may send a suggested timeslot format for the BH-RAN node cell to the BH-RAN node (for example, the WAB node may send a timeslot format for providing BH-RAN node cell selection, or the WAB node may send a timeslot format for indicating the BH-RAN node cell to be used, etc., without specific limitations). Therefore, the aforementioned RRC signaling may also include the timeslot format of the BH-RAN node cell suggested by the WAB node.

[0262] Step 4: After receiving the RRC signaling sent by the WAB node, the BH-RAN node can refer to the information in the RRC signaling to determine the time slot format of each BH-RAN node cell.

[0263] Step 5: The BH-RAN node determines the timeslot format of its cells and then sends a corresponding RRC signaling to the WAB node. This RRC signaling includes the following 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 timeslot format of each cell on the corresponding link.

[0264] In some embodiments, the BH-RAN node may suggest modifications to the time slot format and / or the symbol type of each symbol of the WAB-gNB cell. The RRC signaling may also include the time slot format and / or the symbol type of each symbol of the WAB-gNB cell suggested by the BH-RAN node (exemplarily, the BH-RAN node may send the time slot format and / or the symbol type of each symbol of the WAB-gNB cell selected by the WAB node to the WAB node, or the WAB node may send the time slot format and / or the symbol type of each symbol of the WAB-gNB cell to the BH-RAN node to indicate the time slot format and / or the symbol type of each symbol of the WAB-gNB cell adopted by the WAB node, etc., without specific limitations). The WAB node can configure the WAB-gNB according to the time slot format and / or symbol type suggested by the BH-RAN node.

[0265] Method 1-2: The BH-RAN node initiates RRC signaling to trigger the WAB resource coordination process.

[0266] Step 1: Resource Configuration. The BH-RAN node determines the time slot format of the BH-RAN node cell. The time slot format includes the number and location of uplinks, the number and location of downlinks, and the number and location of flexible symbols.

[0267] Step 2: This step is optional. The BH-RAN node checks whether there is an Xn connection between the BH-RAN node and the WAB node. If so, the BH-RAN node finds that there is no Xn connection between them.

[0268] Step 3: The BH-RAN node sends RRC signaling to the WAB node to coordinate and exchange resource configurations between the two nodes. The RRC signaling includes the following information: BH-RAN node cell list, 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.

[0269] In some embodiments, the BH-RAN node may transmit the proposed time slot format for the WAB-gNB cell and / or the symbol type for each symbol of the WAB-gNB cell. The RRC signaling may also include the proposed time slot format for the WAB-gNB cell and / or the symbol type for each symbol of the WAB-gNB cell from the BH-RAN node.

[0270] Step 4: After receiving the RRC signaling sent by the BH-RAN node, the WAB node can refer to the information in the RRC signaling to determine the time slot format of each WAB-gNB cell and the symbol type of each symbol.

[0271] Step 5: The WAB node determines the timeslot format and symbol type of each WAB-gNB cell, and then sends a corresponding RRC signaling to the BH-RAN node. This RRC signaling includes the following information: WAB node cell list, number of WAB node cells, WAB node cell information, and WAB node duplex capability. The WAB node cell list refers to the list of cells served by the WAB node in the WAB-gNB service. The number of WAB node cells is the number of cells served by the WAB-gNB service. The WAB node cell information includes the timeslot format and / or the symbol type of each cell on the corresponding link (referring to the WAB node cell, which will not be elaborated further below). The WAB node duplex capability includes the following information:

[0272] A WAB node supports simultaneous reception on both WAB-gNB and WAB-MT, or it may not support simultaneous reception on both WAB-gNB and WAB-MT. A WAB node supports simultaneous transmission on both WAB-gNB and WAB-MT, or it may not support simultaneous transmission on both WAB-gNB and WAB-MT. A WAB node supports simultaneous transmission on WAB-gNB and reception on WAB-MT, or it may not support simultaneous transmission on both WAB-gNB and WAB-MT. A WAB node supports simultaneous reception on WAB-gNB and transmission on WAB-MT, or it may not support simultaneous reception on WAB-gNB and transmission on WAB-MT.

[0273] In some embodiments, the WAB node can send a suggested timeslot format for the BH-RAN node cell to the BH-RAN node. Therefore, the aforementioned response RRC signaling may also include the timeslot format for the BH-RAN node cell suggested by the WAB node. The BH-RAN node can configure the serving cell (e.g., the BH-RAN node cell) according to the timeslot format suggested by the WAB node.

[0274] For example, in embodiment two: after the WAB-gNB and the UE's AMF establish an NG interface, if resource configuration and resource coordination are required, an Xn connection is established between the BH-RAN node and the WAB node. Then, the BH-RAN node uses the Xn connection to transmit Xn signaling with the WAB-gNB to complete the purpose of resource coordination.

[0275] Resource coordination can be achieved through at least six of the following methods:

[0276] Method 2-1: The BH-RAN node discovers the WAB-gNB co-located with WAB-MT through a unique identifier (IE) that identifies the WAB-gNB (e.g., the BH-RAN node uses the WAB-gNB identification information in the first message). Then, the WAB node initiates Xn signaling to trigger the WAB resource coordination process.

[0277] Step 1: During the WAB-MT establishment process in the WAB integration process, the WAB-MT sends RRC signaling Msg3 or Msg5, i.e., RRC Setup Request message or RRC Setup Complete message, to the BH-RAN node via the NG-RAN backhaul link. This RRC signaling contains a unique identifier (IE) that identifies the WAB-gNB, such as the WAB-gNB's Global gNB-ID or the IP address used by the WAB-gNB to establish Xn.

[0278] Step 2: During the WAB-gNB establishment process in the WAB integration process (if an Xn link is required in the current situation, then the WAB-gNB can establish an Xn connection with the BH-RAN node and / or other adjacent NG-RAN nodes), the WAB-gNB sends an Xn signaling message to the BH-RAN node, for example, XN SETUP REQUEST, which contains the same identifier IE as in Step 1.

[0279] Step 3: Co-location discovery. The BH-RAN node determines that the WAB-MT and the WAB-gNB are co-located based on the same identifier IE.

[0280] Step 4: Resource Configuration. This is the same as Step 1 in Method 1-1 of Implementation Example 1, and will not be repeated here.

[0281] Step 5: The WAB node detects whether there is an Xn connection between the WAB-gNB and the BH-RAN node, similar to step 2 in method 1-1 of embodiment 1. Thus, the WAB node discovers that there is an Xn connection between them.

[0282] Step 6: The WAB node sends Xn signaling to the BH-RAN node to coordinate and exchange resource configurations between the two nodes. The Xn signaling includes the following information: WAB node cell list, number of WAB node cells, WAB node cell information, and WAB node duplex capability. The WAB node cell list refers to the list of cells served by the WAB node's WAB-gNB service. The number of WAB node cells is the number of cells served by the WAB-gNB service. The WAB node cell information includes the time slot format of each cell on the corresponding link and / or the type of each symbol for each cell. The WAB node duplex capability includes the following information:

[0283] A WAB node supports simultaneous reception on both WAB-gNB and WAB-MT, or it may not support simultaneous reception on both WAB-gNB and WAB-MT. A WAB node supports simultaneous transmission on both WAB-gNB and WAB-MT, or it may not support simultaneous transmission on both WAB-gNB and WAB-MT. A WAB node supports simultaneous transmission on WAB-gNB and reception on WAB-MT, or it may not support simultaneous transmission on both WAB-gNB and WAB-MT. A WAB node supports simultaneous reception on WAB-gNB and transmission on WAB-MT, or it may not support simultaneous reception on WAB-gNB and transmission on WAB-MT.

[0284] In some embodiments, the WAB node can send a suggested timeslot format for the BH-RAN node cell to the BH-RAN node. Therefore, the Xn signaling described above can also include the timeslot format for the BH-RAN node cell suggested by the WAB node.

[0285] Step 7: After receiving the Xn signaling sent by the WAB node, the BH-RAN node can refer to the information in the Xn signaling to determine the time slot format of each BH-RAN node cell.

[0286] Step 8: The BH-RAN node determines the timeslot format of its cells and then sends a response Xn signaling message to the WAB node. This Xn signaling message contains the following 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 timeslot format of each cell on the corresponding link.

[0287] In some embodiments, the BH-RAN node may suggest modifications to the time slot format of the WAB-gNB cell and / or the symbol type of each symbol in the WAB-gNB cell. The Xn signaling may also include the time slot format of the WAB-gNB cell and / or the symbol type of each symbol in the WAB-gNB cell suggested by the BH-RAN node. The WAB node can configure the WAB-gNB according to the time slot format and / or symbol type suggested by the BH-RAN.

[0288] Step 9: When the WAB-gNB changes its identifier, such as changing the Global gNB-ID or the IP address used to establish Xn, the WAB-MT needs to notify the BH-RAN node via RRC signaling or RRC message (such as UEAssistanceInformation).

[0289] Method 2-2: The BH-RAN node discovers the WAB-gNB co-located with the WAB-MT using the unique identifier (IE) that identifies the WAB-gNB. Then, the BH-RAN node initiates Xn signaling to trigger the WAB resource coordination process.

[0290] Step 1: During the WAB-MT establishment process in the WAB integration process, the WAB-MT sends RRC signaling Msg3 or Msg5, i.e., RRC Setup Request message or RRC Setup Complete message, to the BH-RAN node via the NG-RAN backhaul link. This signaling contains a unique identifier (IE) for the WAB-gNB, such as the WAB-gNB's Global gNB-ID or the IP address used by the WAB-gNB to establish Xn.

[0291] Step 2: During the Xn establishment process in the WAB-gNB establishment process of WAB integration, WAB-gNB sends an Xn signaling message to the BH-RAN node, for example, XN SETUP REQUEST, which contains the same identifier IE as in Step 1.

[0292] Step 3: Co-location discovery. The BH-RAN node determines that the WAB-MT and the WAB-gNB are co-located based on the same identifier IE.

[0293] Step 4: Resource Configuration. This is the same as Step 1 in Methods 1-2 of Implementation Example 1, and will not be repeated here.

[0294] Step 5: The BH-RAN node detects whether there is an Xn connection between the BH-RAN node and the WAB node. Thus, the BH-RAN node discovers that there is an Xn connection between them.

[0295] Step 6: The BH-RAN node sends Xn signaling to the WAB node to coordinate and exchange resource configurations between the two nodes. The Xn signaling includes the following information: BH-RAN node cell list, 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.

[0296] In some embodiments, the BH-RAN node may transmit the proposed time slot format of the WAB-gNB cell and / or the symbol type of each symbol of the WAB-gNB cell. The Xn signaling may also include the proposed time slot format of the WAB-gNB cell and / or the symbol type of each symbol of the WAB-gNB cell as specified by the BH-RAN node.

[0297] Step 7: After receiving the Xn signaling sent by the BH-RAN node, the WAB node can refer to the information in the Xn signaling to determine the time slot format of each WAB-gNB cell and the symbol type of each symbol.

[0298] Step 8: The WAB node determines the timeslot format and symbol type of each WAB-gNB cell, and then sends a response Xn signaling to the BH-RAN node. This Xn signaling includes the following information: WAB node cell list, number of WAB node cells, WAB node cell information, and WAB node duplex capability. The WAB node cell list refers to the list of cells served by the WAB node in the WAB-gNB service. The number of WAB node cells is the number of cells served by the WAB-gNB service. The WAB node cell information includes the timeslot format of each WAB-gNB cell on the corresponding link and / or the symbol type of each WAB-gNB cell.

[0300] In some embodiments, the WAB node can send a suggested timeslot format for the BH-RAN node cell to the BH-RAN node. Therefore, the aforementioned response Xn signaling can also include the timeslot format for the BH-RAN node cell suggested by the WAB node. The BH-RAN node can configure the serving cell according to the timeslot format suggested by the WAB node.

[0301] Step 9: When the WAB-gNB changes its identifier, such as changing the Global gNB-ID or the IP address used to establish Xn, the WAB-MT needs to notify the BH-RAN node via an RRC message (such as UEAssistanceInformation).

[0302] Methods 2-3: The BH-RAN node identifies its location by using information such as the cell ID, PCI, and TAC broadcast by the WAB-gNB (e.g., the cell identifier, physical cell identifier (PCI), and tracking area code (TAC) broadcast by the WAB-gNB in ​​the first information) and discovers the WAB-MT co-located with the WAB-gNB. Then, the WAB node initiates Xn signaling to trigger the WAB resource coordination process.

[0303] Step 1: During the WAB-MT establishment process of the WAB integration process, the WAB-MT sends RRC signaling Msg3 or Msg5 to the BH-RAN node through the NG-RAN backhaul link. These are either RRCSetupRequest messages or RRCSetupComplete messages. The RRC signaling contains information such as the cell ID, PCI, and TAC broadcast by the WAB-gNB, which uniquely identifies the node location.

[0304] Step 2: During the Xn establishment process in the WAB-gNB establishment of the WAB integration process, the WAB-gNB sends Xn signaling to the BH-RAN node through the Xn link, for example, XN SETUP REQUEST. This Xn signaling contains information such as cell ID, PCI, and TAC broadcast by the WAB-gNB to indicate the node location.

[0305] Step 3: Co-location discovery. The BH-RAN node determines that the WAB-MT and the WAB-gNB are co-located based on the same location information.

[0306] Step 4: Resource configuration, which is the same as step 1 in method 1-1 of embodiment 1, and will not be repeated here.

[0307] Step 5: The WAB node detects whether there is an Xn connection between the WAB-gNB and the BH-RAN node, which is the same as step 2 in method 1-1 of embodiment 1, and will not be repeated here. Thus, the WAB node discovers that there is an Xn connection between the two.

[0308] Step 6: The WAB node sends Xn signaling to the BH-RAN node to coordinate and exchange resource configurations between the two nodes. The Xn signaling includes the following information: WAB node cell list, number of WAB node cells, WAB node cell information, and WAB node duplex capability.

[0315] Methods 2-4: The BH-RAN node indicates its location using information such as the cell ID, PCI, and TAC broadcast by the WAB-gNB, and discovers the WAB-MT co-located with the WAB-gNB. Then, the BH-RAN node initiates Xn signaling to trigger the WAB resource coordination process.

[0316] Step 1: During the WAB-MT establishment process of the WAB integration process, the WAB-MT sends RRC signaling Msg3 or Msg5 to the BH-RAN node through the NG-RAN backhaul link. These are either RRCSetupRequest messages or RRCSetupComplete messages. The RRC signaling contains information such as the cell ID, PCI, and TAC broadcast by the WAB-gNB, which uniquely identifies the node location.

[0317] Step 2: During the Xn establishment process in the WAB-gNB establishment of the WAB integration process, the WAB-gNB sends Xn signaling to the BH-RAN node through the Xn link, for example, XN SETUP REQUEST.

[0320] Step 5: The BH-RAN node detects whether there is an Xn connection between the BH-RAN node and the WAB node. Thus, the BH-RAN node discovers that there is an Xn connection between them.

[0321] Step 6: The BH-RAN node sends Xn signaling to the WAB node to coordinate and exchange resource configurations between the two nodes. The Xn signaling includes the following information: BH-RAN node cell list, number of BH-RAN node cells, and BH-RAN node cell information.

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.

[0322] Optionally, the BH-RAN node may transmit the suggested time slot format for the WAB-gNB cell and / or the symbol type for each symbol of the WAB-gNB cell. The Xn signaling may also include the suggested time slot format for the WAB-gNB cell and / or the symbol type for each symbol of the WAB-gNB cell from the BH-RAN node.

[0323] Step 7: After receiving the Xn signaling sent by the BH-RAN node, the WAB node can refer to the information in the Xn signaling to determine the time slot format of each WAB-gNB cell and the symbol type of each symbol.

[0324] Step 8: The WAB node determines the timeslot format for each WAB-gNB cell and the symbol type for each symbol, and then sends a response Xn signaling to the BH-RAN node.

[0326] In some embodiments, the WAB node can send a suggested timeslot format for the BH-RAN node cell to the BH-RAN node. Therefore, the aforementioned response Xn signaling can also include the timeslot format for the BH-RAN node cell suggested by the WAB node. The BH-RAN node can configure the serving cell according to the timeslot format suggested by the WAB node.

[0327] Step 9: When the WAB node location changes, such as when the cellID, PCI, and TAC broadcast by WAB-gNB are changed, WAB-MT needs to notify the BH-RAN node via RRC messages (such as UEAssistanceInformation).

[0328] Method 2-5: The WAB-gNB sends an Xn signaling message to the BH-RAN node. This Xn signaling message contains an identifier (IE) that identifies the WAB-MT that co-located with it. The BH-RAN node discovers the WAB-gNB that co-located with the WAB-MT through this identifier (for example, through the WAB-MT identification information in the first message, or through the WAB-MT identification information in the second message that indicates the WAB-gNB co-located with it), thereby establishing a co-location relationship. Afterwards, the WAB node initiates the Xn signaling message to trigger the WAB resource coordination process.

[0329] Step 1: During the WAB-MT establishment process in the WAB integration process, the WAB-MT establishes an RRC connection with the serving cell of the BH-RAN node via the NG-RAN backhaul link. During the RRC connection establishment process, the BH-RAN node allocates a C-RNTI for the WAB-MT in the serving cell.

This signaling message contains the WAB-MT identifier IE, including the cell identifier (Cell Identity) and C-RNTI of the serving WAB-MT cell.

[0331] Step 3: The BH-RAN node determines that the WAB-MT and the WAB-gNB are co-located based on the same identifier IE.

[0332] Step 4: Resource Configuration. This is the same as Step 1 in Method 1-1 of Implementation Example 1, and will not be repeated here.

[0333] Step 5: The WAB node detects whether there is an Xn connection between the WAB-gNB and the BH-RAN node, similar to step 2 in method 1-1 of embodiment 1. Thus, the WAB node discovers that there is an Xn connection between them.

[0334] Step 6: The WAB node sends Xn signaling to the BH-RAN node to coordinate and exchange resource configurations between the two nodes. The Xn signaling includes the following information: WAB node cell list, number of WAB node cells, WAB node cell information, and WAB node duplex capability. The WAB node cell list refers to the list of cells served by the WAB node's WAB-gNB service. The number of WAB node cells is the number of cells served by the WAB-gNB service.

[0336] In some embodiments, the WAB node can send a suggested timeslot format for the BH-RAN node cell to the BH-RAN node. Therefore, the Xn signaling described above can also include the timeslot format for the BH-RAN node cell suggested by the WAB node.

[0337] Step 7: After receiving the Xn signaling sent by the WAB node, the BH-RAN node can refer to the information in the Xn signaling to determine the time slot format of each BH-RAN node cell.

[0338] Step 8: The BH-RAN node determines the timeslot format of its cells and then sends a response Xn signaling message to the WAB node. This Xn signaling message contains the following information: the BH-RAN node cell list, the number of BH-RAN node cells, and BH-RAN node cell information.

The WAB node can configure the WAB-gNB according to the time slot format and / or symbol type suggested by the BH-RAN.

[0340] Step 9: When the identifier of WAB-MT changes, such as when the serving cell or C-RNTI of WAB-MT changes, WAB-gNB needs to notify the BH RAN node via Xn message (e.g., NG-RAN NODE CONFIGURATION UPDATE).

[0341] Method 2-6: The WAB-gNB sends an Xn signaling message to the BH-RAN node. The Xn signaling message contains an identifier (IE) that identifies the WAB-MT that shares the same address with it. The BH-RAN node uses this identifier (IE) to discover the WAB-gNB that shares the same address with the WAB-MT, thereby establishing a co-location relationship. Subsequently, the BH-RAN node initiates the Xn signaling message to trigger the WAB resource coordination process.

[0342] Step 1: During the WAB-MT establishment process in the WAB integration process, the WAB-MT establishes an RRC connection with the serving cell of the BH-RAN node via the NG-RAN backhaul link. During the RRC connection establishment process, the BH-RAN node allocates a C-RNTI for the WAB-MT in the serving cell.

[0343] Step 2: During the Xn establishment process in the WAB-gNB establishment process of WAB integration, WAB-gNB sends an Xn signaling message to the BH-RAN node, for example, XN SETUP REQUEST. This Xn signaling message contains the WAB-MT identifier IE, including the cell identity and C-RNTI of the serving WAB-MT cell.

[0344] Step 3: The BH-RAN node determines that the WAB-MT and the WAB-gNB are co-located based on the same identifier IE.

[0345] Step 4: Resource Configuration. This is the same as Step 1 in Methods 1-2 of Implementation Example 1, and will not be repeated here.

[0346] Step 5: The BH-RAN node detects whether there is an Xn connection between the BH-RAN node and the WAB node. Thus, the BH-RAN node discovers that there is an Xn connection between them.

[0349] Step 7: After receiving the Xn signaling sent by the BH-RAN node, the WAB node can refer to the information in the Xn signaling to determine the time slot format of each WAB-gNB cell and the symbol type of each symbol.

[0350] Step 8: The WAB node determines the timeslot format for each WAB-gNB cell and the symbol type for each symbol, and then sends a response Xn signaling to the BH-RAN node.

A WAB node supports simultaneous reception on WAB-gNB and transmission on WAB-MT, or it may not support simultaneous reception on WAB-gNB and transmission on WAB-MT.

[0352] In some embodiments, the WAB node can send a suggested timeslot format for the BH-RAN node cell to the BH-RAN node. Therefore, the aforementioned response Xn signaling can also include the timeslot format for the BH-RAN node cell suggested by the WAB node. The BH-RAN node can configure the serving cell according to the timeslot format suggested by the WAB node.

[0353] Step 9: When the identifier of WAB-MT changes, such as when the serving cell or C-RNTI of WAB-MT changes, WAB-gNB needs to notify the BH RAN node via Xn message (e.g., NG-RAN NODE CONFIGURATION UPDATE).

[0354] In this application, after the WAB integration process is completed, the WAB node is simultaneously connected to both the UE and the BH-RAN node. Transmissions on the access link and the backhaul link may interfere with each other. Therefore, simultaneous transmission via the access link and backhaul link will be subject to some limitations. The WAB node and the BH-RAN node negotiate resources for the WAB node's access link and backhaul link. If an Xn connection exists between the WAB node and the BH-RAN node, the WAB node can use Xn signaling to coordinate resource configuration. When a BH-RAN node simultaneously serves multiple WAB-MTs (i.e., the gNB is connected to multiple WAB nodes), the BH-RAN node can obtain information via RRC signaling on the NG-RAN backhaul link and via Xn signaling on the Xn link to find the WAB-gNB co-located with the WAB-MT and establish a co-location relationship. WAB nodes can also use RRC signaling for coordination (e.g., when there is no Xn connection) to avoid potential conflicts between WAB-MT scheduling and the corresponding WAB-gNB service UE scheduling, as well as interference between access links and backhaul links, thus ensuring service quality.

[0355] Therefore, whether or not an Xn connection is established between a WAB node and a BH-RAN node, the WAB node uses RRC signaling or Xn signaling to coordinate resources with the BH-RAN node, exchanging resource configuration information or sending suggested resource configurations. If a BH-RAN node is connected to multiple WAB nodes, the BH-RAN node uses RRC and Xn signaling for co-location discovery to obtain the mapping between WAB-gNB and WAB-MT, and then performs resource coordination to avoid interference between access links and backhaul links, ensuring service quality.

[0356] It should be noted that the resource coordination method with WAB nodes as the execution subject provided in this application can be found in the following specific implementation process: Figures 1-6 The specific implementation process of the embodiments shown, including Embodiment 1 (e.g., mode 1-1) to Embodiment 2 (e.g., mode 2-1, mode 2-3, mode 2-5), will not be described in detail here.
