Description

Technical Field

[0001] The present application relates to the field of communications, and more particularly, to a method and apparatus for resource configuration. Background Art

[0002] With the continuous development of mobile communication technology, spectrum resources are becoming increasingly scarce. To improve spectrum utilization, future base station deployments will be denser. Furthermore, dense deployment can prevent coverage holes. In traditional cellular network architectures, base stations connect to the core network via optical fiber. However, in many scenarios, optical fiber deployment is very expensive. Wireless relay nodes (RNs) connect to the core network via wireless backhaul links, saving some of the optical fiber deployment costs.

[0003] Generally, a relay node establishes a wireless backhaul link with one or more upper-level nodes and accesses the core network through the upper-level nodes. The upper-level node can perform certain control on the relay node through various signaling (for example, data scheduling, timing modulation, power control, etc.). In addition, the relay node can provide services to multiple lower-level nodes. The upper-level node of the relay node can be a base station or another relay node; the lower-level node of the relay node can be a terminal or another relay node. Considering the high bandwidth of future wireless networks, the 5G new radio (NR) considers introducing an integrated access and backhaul (IAB) solution to further reduce deployment costs and improve deployment flexibility, and thereby introduces an integrated access and backhaul relay, namely an IAB node.

[0004] An IAB node consists of two functional units: a mobile terminal (MT) and a distributed unit (DU). The MT is used for communication between the IAB node and its upper-level node, while the DU is used for communication between the IAB node and its lower-level nodes. In multi-antenna panel or multi-cell scenarios, there is no solution for configuring MT and DU resources in IAB nodes. Summary of the Invention

[0005] In view of this, the present application provides a method and device for resource configuration, which indicates to the IAB node the multiplexing type corresponding to each antenna panel of one or more antenna panels of the first functional unit and the second functional unit, so that the IAB node obtains the resource configuration of the MT or the resource configuration of the DU based on the multiplexing type, which helps to realize the resource configuration of the IAB node under multiple panels.

[0006] In a first aspect, a method for resource configuration is provided, comprising: a first node receiving first indication information sent by a second node, the first indication information being used to indicate a resource multiplexing type between each of one or more antenna panels of a first functional unit and a second functional unit; the first node using resources of the one or more antenna panels of the second functional unit for data transmission, wherein the resource type of the one or more antenna panels of the second functional unit is determined based on the resource multiplexing type. Therefore, after obtaining the resource multiplexing type, the first node can determine the resources of the one or more antenna panels of the second functional unit in combination with the resource configuration of the first functional unit, thereby implementing resource configuration in a multi-antenna panel IAB node.

[0007] In one possible implementation, the method further includes: the first node receiving resource configuration information from the second node, the resource configuration information being used to indicate resources of one or more antenna panels of a first functional unit in the first node; wherein the resources of the one or more antenna panels of the second functional unit are determined based on the resource reuse type, the resources of the one or more antenna panels of the first functional unit, and a preset relationship, wherein the preset relationship includes a correspondence between the resource configuration of the first functional unit and the resource configuration of the second functional unit under different resource reuse types of the first node. Therefore, the first node can also obtain the resource configuration of the first functional unit from the second node, and then use the resource configuration of the first functional unit to search for the resource configuration of the second functional unit in the above-mentioned preset relationship.

[0008] In one possible implementation, the method further includes: the first node sending second indication information to the second node, where the second indication information is used to indicate the resource multiplexing type supported by each antenna panel of the first functional unit and the second functional unit, or used to indicate the resource multiplexing type supported by the first antenna panel of the first functional unit and the second functional unit, where the first antenna panel represents an antenna panel with the same direction as the antenna panel used by the second functional unit, or used to indicate the resource multiplexing type supported by the second antenna panel of the first functional unit and the second functional unit, where the second antenna panel represents an antenna panel with a different direction from the antenna panel used by the second functional unit. Therefore, the first node can report the supported resource multiplexing type to the second node, so that the second node can configure the resource multiplexing type for the first node with reference to the resource multiplexing type reported by the first node.

[0009] Optionally, the first functional unit is a mobile terminal MT, and the second functional unit is a distributed unit DU; or, the first functional unit is a distributed unit DU, and the second functional unit is a mobile terminal MT.

[0010] In one possible implementation, when determining the resource configuration of a DU, the method further includes: if there is a signal to be transmitted in the DU or MT of the first node, the first node adjusts the resources in the resource configuration of the DU, wherein the resources corresponding to the signal to be transmitted are first-category resources. Therefore, for some special signals to be transmitted, in order to ensure smooth transmission of these signals to be transmitted, the first node can adjust the resources in the resource configuration of the DU. "Adjustment" can be interpreted as adjusting soft resources or unavailable resources to hard resources; or adjusting hard resources to soft resources or unavailable resources.

[0011] Optionally, the signal to be transmitted includes one or more of the following signals: a synchronization signal block SSB, a random access channel RACH signal.

[0012] Optionally, if there is a signal to be transmitted in the DU of the first node, the first node adjusts the resource configuration of the DU, including: if the first node determines that the first resource in the resource configuration of the DU is a second-category resource, the first node adjusts the first resource to a first-category resource, wherein the first resource is a resource used by the DU of the first node to transmit the signal to be transmitted. In order to ensure smooth transmission of the signal to be transmitted in the DU, it is necessary to ensure that the resource used to transmit the signal to be transmitted in the resource configuration of the DU is a hard resource. Therefore, if the first resource in the resource configuration of the DU is a soft resource or an unavailable resource, the first resource is converted to a hard resource.

[0013] Optionally, if there is a signal to be transmitted in the MT of the first node, the first node adjusts the resource configuration of the DU, including: if the first node determines that the second resource in the resource configuration of the DU is a first-category resource, the first node adjusts the second resource to a second-category resource, wherein the second resource is a resource that overlaps in the time domain with the resource used to transmit the signal to be transmitted in the MT of the first node. In order to ensure smooth transmission of the signal to be transmitted in the MT, it is necessary to ensure that the resource used to transmit the signal to be transmitted in the resource configuration of the MT is a hard resource. Therefore, the second resource can be converted into a soft resource or an unavailable resource, thereby ensuring smooth transmission of the signal to be transmitted in the MT.

[0014] A second aspect provides a method for resource configuration, comprising: a second node determining first indication information, the first indication information being used to indicate a resource multiplexing type between each of the one or more antenna panels of the first functional unit and the second functional unit, the resource multiplexing type being used by the first node to determine resources of the one or more antenna panels of the second functional unit; and the second node sending the first indication information to the first node. Therefore, by sending the resource multiplexing type between each of the one or more antenna panels of the first functional unit and the second functional unit to the first node, the second node determines the resources of the one or more antenna panels of the second functional unit based on the resource multiplexing type and the resource configuration of the first functional unit, thereby implementing resource configuration in an IAB node with multiple antenna panels.

[0015] In one possible implementation, the method further includes: the second node sending resource configuration information to the first node, where the resource configuration information indicates resources of one or more antenna panels of a first functional unit in the first node. Therefore, by sending the resource configuration of the first functional unit to the first node, the second node causes the first node to use the resource configuration of the first functional unit to search for the resource configuration of the second functional unit in a preset relationship.

[0016] In one possible implementation, the method further includes: the second node receiving second indication information sent by the first node, the second indication information being used to indicate the resource multiplexing type supported by each antenna panel of the first functional unit and the second functional unit, or being used to indicate the resource multiplexing type supported by the first antenna panel of the first functional unit and the second functional unit, the first antenna panel representing an antenna panel with the same direction as the antenna panel used by the second functional unit, or being used to indicate the resource multiplexing type supported by the second antenna panel of the first functional unit and the second functional unit, the second antenna panel representing an antenna panel with a different direction than the antenna panel used by the second functional unit; wherein the second node determining the first indication information includes: the second node determining the first indication information based on the second indication information. Therefore, by receiving the resource multiplexing type supported by the first node reported by the first node, the second node can configure the resource multiplexing type for the first node with reference to the resource multiplexing type reported by the first node.

[0017] Optionally, the first functional unit is a mobile terminal MT, and the second functional unit is a distributed unit DU; or, the first functional unit is a distributed unit DU, and the second functional unit is a mobile terminal MT.

[0045] The technical solution in this application will be described below with reference to the accompanying drawings.

[0046] In the description of the embodiments of the present application, unless otherwise specified, "a plurality of" or "a plurality of" means two or more. In addition, "at least one" can be replaced by "one or more".

[0047] It should be understood that the names of all nodes and messages in this application are merely names set for the convenience of description in this application. The names in the actual network may be different. This application should not be understood as limiting the names of various nodes and messages. On the contrary, any name with the same or similar function as the node or message used in this application is regarded as a method or equivalent replacement of this application, and is within the scope of protection of this application. No further details will be given below.

[0048] Taking into account the high bandwidth of future wireless networks, the fifth generation (5G) new radio (NR) considers introducing an integrated access and backhaul (IAB) solution to further reduce deployment costs and improve deployment flexibility, and thereby introduces an integrated access and backhaul relay. In this application, the relay node that supports integrated access and backhaul is referred to as an IAB node to distinguish it from the relay of long term evolution (LTE). The system including the IAB node is also called a relay system.

[0049] In order to better understand the resource configuration method and device disclosed in the embodiment of this application, the network architecture used in the embodiment of the present invention is described below. Figure 1 , Figure 1 A schematic diagram of the structure of a communication system applicable to an embodiment of the present application.

[0050] It should be noted that the communication systems mentioned in the embodiments of the present application include but are not limited to: narrowband Internet of Things (NB-IoT) system, wireless local access network (WLAN) system, LTE system, next-generation 5G mobile communication system or communication system after 5G, such as NR, device to device (D2D) communication system.

[0051] exist Figure 1In the communication system shown, an integrated access and backhaul IAB system is provided. An IAB system includes at least one base station 100, one or more terminal devices (terminal) 101 served by the base station 100, one or more relay nodes IAB nodes, and one or more terminal devices 111 served by the IAB node 110. Usually, the base station 100 is called a donor base station (donor next generation node B, DgNB), and the IAB node 110 is connected to the base station 100 via a wireless backhaul link 113. The donor base station is also referred to as a donor node in this application, that is, a donor node. Base stations include but are not limited to: evolved node base (eNB), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home evolved NodeB, or home node B, HNB), baseband unit (BBU), eLTE (evolved LTE, eLTE) base station, NR base station (next generation node B, gNB), etc. Terminal devices include, but are not limited to, user equipment (UE), mobile stations, access terminals, subscriber units, user stations, mobile stations, remote stations, remote terminals, mobile devices, terminals, wireless communication devices, user agents, stations (ST) in wireless local access networks (WLANs), cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, mobile stations in future 5G networks, and terminal devices in future evolved public land mobile networks (PLMNs). An IAB node is a specific name for a relay node and does not limit the solutions of the embodiments of the present application. It can be one of the above-mentioned base stations or terminal devices with forwarding capabilities, or it can be an independent device.

[0052] The integrated access and backhaul system may also include multiple other IAB nodes, such as IAB node 120 and IAB node 130. IAB node 120 is connected to IAB node 110 via wireless backhaul link 123 to access the network, and IAB node 130 is connected to IAB node 110 via wireless backhaul link 133 to access the network. IAB node 120 serves one or more terminal devices 121, and IAB node 130 serves one or more terminal devices 131. Figure 1 In the embodiment, IAB node 110 and IAB node 120 are both connected to the network via wireless backhaul links. In this application, the wireless backhaul links are viewed from the perspective of relay nodes. For example, wireless backhaul link 113 is the backhaul link of IAB node 110, and wireless backhaul link 123 is the backhaul link of IAB node 120. Figure 1 As shown, an IAB node, such as 120, can be connected to another IAB node 110 via a wireless backhaul link, such as 123, thereby connecting to the network. In addition, the relay node can be connected to the network through multiple levels of wireless relay nodes. It should be understood that the use of IAB nodes in this application is only for descriptive purposes and does not mean that the solution of this application is only used in NR scenarios. In this application, IAB nodes can generally refer to any node or device with relay functionality. The use of IAB nodes and relay nodes in this application should be understood to have the same meaning.

[0053] For the convenience of description, the basic terms or concepts used in the embodiments of this application are defined below.

[0054] Upper-level node: The node that provides wireless backhaul link resources, such as 110, is called the upper-level node of the IAB node 120. It should be understood that the upper-level node can be an IAB node, a donor base station (such as a donor node), or a network device, etc., without limitation.

[0055] Lower-level node: A node that uses backhaul link resources to transmit data to the network or receives data from the network is called a lower-level node. For example, 120 is called a lower-level node of relay node 110, and 131 can be a lower-level node of 130. The network is a network above the core network or other access network, such as the Internet, a private network, etc.

[0056] Access link: An access link is the wireless link used by a node to communicate with its lower-level nodes, including both uplink and downlink transmission links. Uplink transmission on an access link is also called access link uplink transmission, and downlink transmission is also called access link downlink transmission. Nodes include but are not limited to the aforementioned IAB nodes.

[0057] Backhaul link: A backhaul link is the wireless link used by a node to communicate with its parent node, including both uplink and downlink transmissions. Uplink transmission on a backhaul link is also called uplink transmission, and downlink transmission is also called downlink transmission. Nodes in this link include but are not limited to the aforementioned IAB nodes.

[0058] In another description, the IAB node can be divided into two parts, namely the mobile terminal (MT) and the distributed unit (DU). Among them, the MT is used for the IAB node to communicate with the upper node, and the DU is used for the IAB node to communicate with the lower node. The link between the MT in the IAB node and the upper node is called the upper backhaul link (parentBH link), the link between the DU in the IAB node and its lower IAB node is called the lower backhaul link (childBHlink), and the link between the DU in the IAB node and the subordinate UE is called the access link (access link). However, in this application, for the convenience of description, the link between the IAB node and the upper node is called the backhaul link, and the link between the IAB node and the lower IAB node and / or UE is collectively referred to as the access link.

[0059] Generally, a lower-level node can be regarded as a terminal device of an upper-level node. Figure 1 In the integrated access and backhaul system shown, one IAB node is connected to one upper-level node. However, in future relay systems, to improve the reliability of wireless backhaul links, one IAB node, such as 120, may have multiple upper-level nodes simultaneously providing services. For example, IAB node 130 shown in the figure can also be connected to IAB node 120 via backhaul link 134. That is, IAB node 110 and IAB node 120 are both upper-level nodes of IAB node 130. The names of IAB nodes 110, 120, and 130 do not limit the scenarios or networks in which they are deployed and can be any other names, such as relay, RN, etc. The term "IAB node" is used in this application for convenience of description.

[0060] exist Figure 1In the embodiment, the wireless links 102, 112, 122, 132, 113, 123, 133, 134 can be bidirectional links, including uplink and downlink transmission links. In particular, the wireless backhaul links 113, 123, 133, 134 can be used for the upper node to provide services to the lower node, such as the upper node 100 provides wireless backhaul services to the lower node 110. It should be understood that the uplink and downlink of the backhaul link can be separated, that is, the uplink and downlink are not transmitted through the same node. The downlink transmission refers to the transmission of information or data from the upper node, such as node 100, to the lower node, such as node 110, and the uplink transmission refers to the transmission of information or data from the lower node, such as node 110, to the upper node, such as node 100. The node is not limited to being a network node or a terminal device. For example, in a D2D scenario, a terminal device can act as a relay node to serve other terminal devices. In some scenarios, the wireless backhaul link can also be an access link. For example, the backhaul link 123 can also be regarded as an access link for the node 110, and the backhaul link 113 is also an access link for the node 100. It should be understood that the upper-level node can be a base station or a relay node, and the lower-level node can be a relay node or a terminal device with relay function. For example, in a D2D scenario, the lower-level node can also be a terminal device.

[0061] Figure 1The relay nodes shown, such as 110, 120, and 130, can exist in two forms: one is to exist as an independent access node, which can independently manage terminal devices accessing the relay node. In this case, the relay node usually has an independent physical cell identifier (PCI). This form of relay usually requires a complete protocol stack function, such as radio resource control (RRC) function. This type of relay is usually called a layer 3 relay; and the other form of relay node and donor node, such as donor eNB and donor gNB, belong to the same cell, and user management is managed by the host base station, such as the donor node. This type of relay is usually called a layer 2 relay. The layer 2 relay usually exists as the DU of the base station DgNB under the NR control and bearer separation (central unit and distributed unit, CU-DU) architecture, and communicates with the CU through the F1 application protocol (F1 application protocol, F1-AP) interface or the tunnel protocol, where the tunnel protocol can be, for example, the general packet radio service tunneling protocol (general packet radio service tunneling protocol, GTP protocol), which will not be repeated here. A donor node refers to a node through which the core network can be accessed, or an anchor base station of a wireless access network, through which the network can be accessed. The anchor base station is responsible for receiving data from the core network and forwarding it to the relay node, or receiving data from the relay node and forwarding it to the core network. Usually, the donor node in the relay system is called an IAB donor, that is, a host node. The two terms may be used interchangeably in this application. It should be understood that the IAB donor and the host node should not be understood as entities or network elements with different functions.

[0062] In an embodiment of the present application, a relay node (such as an IAB node) or a terminal device or a network device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a Windows operating system. The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. In addition, the embodiment of the present application does not specifically limit the specific structure of the execution subject of the method provided in the embodiment of the present application. As long as it is possible to communicate according to the method provided in the embodiment of the present application by running a program that records the code of the method provided in the embodiment of the present application, for example, the execution subject of the method provided in the embodiment of the present application can be a terminal device or a network device, or a functional module in a terminal device or a network device that can call a program and execute the program.

[0063] In addition, various aspects or features of the present application can be implemented as methods, devices or products using standard programming and / or engineering techniques. The term "product" as used in this application covers computer programs that can be accessed from any computer-readable device, carrier or medium. For example, computer-readable media may include, but are not limited to: magnetic storage devices (e.g., hard disks, floppy disks or tapes, etc.), optical disks (e.g., compact discs (CDs), digital versatile discs (DVDs), etc.), smart cards and flash memory devices (e.g., erasable programmable read-only memories (EPROMs), cards, sticks or key drives, etc.). In addition, the various storage media described herein may represent one or more devices and / or other machine-readable media for storing information. The term "machine-readable medium" may include, but is not limited to, wireless channels and various other media capable of storing, containing and / or carrying instructions and / or data.

[0064] To facilitate understanding, some terms or concepts involved in the embodiments of this application are explained here.

[0065] MT resources: refers to the resources used by the MT function of the IAB node. MT resources can be configured as uplink (U) resources, downlink (D) resources, and flexible (F) resources.

[0066] In addition, MT resources can be divided into the following two types:

[0067] Available resources refer to resources that may be scheduled by the upper-level node;

[0068] Unavailable (null, N) resources refer to resources that will not be scheduled by the upper node. Those skilled in the art should understand that in actual use, unavailable resources can also be recorded as "NULL", which does not limit the embodiments of the present application.

[0069] In the embodiment of the present application, the available and unavailable resources of the MT can be explicitly configured by the upper node through high-level signaling (such as RRC signaling), or can be implicitly derived by the IAB node through the DU resource type. The embodiment of the present application does not limit the method by which the available and unavailable resources of the MT are obtained.

[0070] DU resources: These are the resources used by the DU function of the IAB node. DU resources can be configured as uplink (U), downlink (D), flexible (F), and null (N). Furthermore, DU uplink resources can be divided into soft (S) and hard (H). DU downlink resources can be divided into soft and hard resources. DU flexible resources can be divided into soft and hard resources.

[0071] Soft resources: refers to whether the resources can be used by the DU, which depends on the instructions of the upper node.

[0072] Hard resources: refers to resources that are always available to the DU.

[0073] In this application, the soft resources and hard resources of the DU can be explicitly configured by the upper node through high-level signaling (e.g., RRC signaling) or interface messages (e.g., F1-AP interface messages or enhanced F1-AP interface messages), or can be implicitly derived by the IAB node through the resource configuration of the MT. This application does not limit how the soft resources and hard resources of the DU are obtained.

[0074] The MT and DU resources in an IAB node can have different resource multiplexing types, such as time-division multiplexing (TDM), static space division multiplexing (SDM), dynamic SDM, full-duplex multiplexing, etc. Under different resource multiplexing types, the resource configuration of the MT resources and the resource configuration of the DU resources can have different corresponding relationships. For example, if the resource multiplexing type is TDM, the MT and DU of the IAB node cannot transmit simultaneously; if the resource multiplexing type is SDM, the MT and DU can receive or transmit simultaneously; if the resource multiplexing type is full-duplex, the MT and DU can transmit simultaneously, and are not restricted to simultaneous reception or transmission.

[0075] Figure 2 A schematic diagram showing an example of a multi-antenna panel scenario is shown. Figure 2 As shown, the IAB node has multiple antenna panels (for example, three antenna panels, namely antenna panel 0, antenna panel 1 and antenna panel 2). The IAB node can use multiple antenna panels to communicate with the upper node, the lower node or the access UE. It should be understood that the embodiment of the present application does not limit the number of antenna panels of the IAB node. Figure 2 The description is made by taking three antenna panels as an example.

[0076] Figure 3 Schematic interactive diagram of a resource configuration method 200 according to an embodiment of the present application is shown. Figure 3 As shown, the method 200 includes:

[0077] S210: The second node sends first indication information to the first node, where the first indication information is used to indicate a resource multiplexing type between each of one or more antenna panels of the first functional unit and the second functional unit. Correspondingly, the first node receives the first indication information.

[0078] The first node may be a relay node, such as an IAB node.

[0079] The second node may be a superior node of the first node. The description of the superior node can be found above and will not be repeated here. Here, when the second node is an IAB node, the signaling sent by the IAB node to the first node may be generated by the superior node of the second node (such as a donor node) and sent to the second node; and the signaling sent by the first node to the second node may also be sent by the second node to the superior node of the second node.

[0080] The resource multiplexing type between each of the one or more antenna panels of the first functional unit and the second functional unit is configured by the second node for the first node. The resource multiplexing type can be time division multiplexing (TDM), static space division multiplexing (SDM), dynamic SDM, full-duplex multiplexing, etc.

[0081] Here, the first functional unit may be a mobile terminal MT, and correspondingly, the second functional unit may be a distributed unit DU; or, the first functional unit may be a distributed unit DU, and the second functional unit may be a mobile terminal MT.

[0082] It should be understood that, for the sake of ease of description, the embodiments of the present application are described using antenna panels as an example, but this does not limit the scope of protection of the embodiments of the present application. The technical solutions of the embodiments of the present application are not only applicable to different antenna panels, but also to different cells and different subunits. That is, different antenna panels can be replaced with different cells; or, replaced with different subunits, for example, the DU of the IAB node has multiple subunits, or the MT of the IAB node has multiple subunits. Among them, for the MT, the subunit can be represented by a cell, a cell group, a carrier, a carrier group or a bandwidth part (Bandwidth part, BWP). For example, when the MT adopts carrier aggregation transmission, the MT has multiple cells or multiple carriers, and the multiple cells or multiple carriers are the subunits of the MT; when the MT adopts multi-connection transmission, the MT has multiple cell groups or carrier groups, and the multiple cell groups or carrier groups are the subunits of the MT. For the DU, the subunit can be represented by a cell, a cell group, a carrier, a carrier group or an antenna panel. For example, a DU may have panels with multiple orientations, and each antenna panel corresponds to a cell. Therefore, a subunit may be represented by an antenna panel or a cell. For another example, a DU may have multiple carriers, and each carrier corresponds to a cell. Therefore, a subunit may be represented by a carrier or a cell.

[0083] Taking the case where the first functional unit is a DU and the second functional unit is an MT as an example, the second node may indicate that each antenna panel of the DU has a different resource configuration, and the resource configuration corresponding to each antenna panel is different from the resource multiplexing type of the MT resources; or, it may indicate that the resources of each cell of the DU have a different resource configuration, and the resource multiplexing type of the MT resources corresponding to each cell is different; or, it may indicate that the resources of each subunit of the DU have a different resource configuration, and the resource multiplexing type of each subunit is different from that of the MT resources. Here, those skilled in the art should understand that the resource multiplexing of DU resources and MT resources can be understood as the multiplexing of resources when transmitting signals on the resources corresponding to each antenna panel / each cell / each subunit.

[0084] Optionally, different antenna panels may correspond to different cell identifiers (IDs), or may correspond to the same cell ID, which is not limited.

[0085] For example, in one possible implementation, when an IAB node provides services to a subordinate node or UE, the DU can support the operation of multiple cells, each with different cell IDs. Optionally, different cells utilize different antenna panels, and the second node can configure the resource reuse type between the different cells of the DU of the first node and the mobile terminal. In another possible implementation, the mobile terminal of the IAB node establishes connections with multiple superior nodes, meaning that the mobile terminal may communicate with different cells.

[0086] It should be understood that when the second node configures the above resource reuse type for the first node, it can refer to the resource reuse type supported by the first node reported by the first node, or it can configure it itself, and there is no limitation on this.

[0087] For the situation where the first node does not report the resource multiplexing type supported by the first node, or even if the first node reports the resource multiplexing type supported by the first node, the second node can configure the resource multiplexing type of all antenna panels of MT and DU to be TDM, or can configure the resource multiplexing type of MT and DU when using the same antenna panel to be TDM, and the resource multiplexing type when using different antenna panels with DU to be semi-static SDM or dynamic SDM.

[0088] "Same antenna panel" means that the MT and DU use the same antenna panel, or that the antenna panel used by the MT and the DU face the same direction. "Different antenna panels" means that the MT and DU use different antenna panels, or that the antenna panels used by the MT and the DU face different directions.

[0089] In the embodiment of the present application, "same antenna panel" can be represented by other concepts or terms, such as co-location, quasi-co-location, same orientation, strong correlation, mutual influence, etc., which are uniformly explained here and will not be repeated below. In another possible implementation, before the second node displays the configuration resource multiplexing type for the first node, the MT and DU of the first node adopt the default resource multiplexing type. Among them, the default resource multiplexing type includes: the resource multiplexing type of all antenna panels of the MT and DU is TDM, or the resource multiplexing type when the MT and DU use the same antenna panel is TDM, and the resource multiplexing type when the MT and DU use different antenna panels is semi-static SDM or dynamic SDM.

[0090] For a case where the first node reports to the second node the resource reuse types supported by the first node, optionally, the method 200 further includes:

[0091] S220, the first node sends second indication information to the second node, where the second indication information is used to indicate the resource multiplexing type supported by each antenna panel of the first functional unit and the second functional unit, or is used to indicate the resource multiplexing type supported by the first antenna panel of the first functional unit and the second functional unit, where the first antenna panel represents an antenna panel with the same direction as the antenna panel used by the second functional unit, or the first antenna panel is the same antenna panel used by the first functional unit and the second functional unit; or is used to indicate the resource multiplexing type supported by the second antenna panel of the first functional unit and the second functional unit, where the second antenna panel represents an antenna panel with a different direction from the antenna panel used by the second functional unit. That is, the first node can report to the second node the co-location relationship between the antenna panel used by the MT and the antenna panel of the DU (the co-location relationship is used to indicate whether the antenna panel used by the MT is the same as the antenna panel used by the DU).

[0092] For example, if the first functional unit is a DU and the second functional unit is an MT, the first node can use second indication information to report to the second node the resource multiplexing types supported by each antenna panel of the DU and the MT. Specifically, when the MT uses one or more antenna panels for transmission, the resource multiplexing types used by the MT and the different antenna panels of the DU. Accordingly, the second node can determine whether the MT and the DU share the same antenna panel based on the resource multiplexing types supported by each antenna panel of the DU and the MT reported by the first node.

[0093] Alternatively, illustratively, the first node may report to the second node, through the second indication information, the resource multiplexing type supported by the first antenna panel in the DU and the MT, or the resource multiplexing type supported by the second antenna panel in the DU and the MT. Furthermore, the second indication information may also include an identifier of the first antenna panel.

[0094] Optionally, the second indication information may also indicate an identifier of the first antenna panel or an identifier of the second antenna panel. It should be understood that the identifier of the antenna panel may be a panel ID or a cell ID, or may be distinguished by a reference signal identifier or a reference signal resource identifier, such as a synchronization signal block (SSB) identifier, a channel state information-reference signal (CSI-RS) identifier, a CSI-RS resource identifier, a sounding reference signal (SRS) resource identifier, etc., without limitation.

[0095] Specifically, the first node and / or the second node can distinguish different antenna panels by reference signal identifiers. For example, for downlink reference signal set 0 and downlink reference signal set 1, each downlink reference signal set contains at least one downlink reference signal. The MT uses antenna panel 0 when receiving or transmitting downlink reference signal set 0, and uses antenna panel 1 when receiving or transmitting downlink reference signal set 1. Therefore, the first node should report the resource multiplexing type of the MT and the DU when the MT transmits and receives downlink reference signal set 0 and downlink reference signal set 1, or the co-location relationship between the antenna panels of the MT and the DU. For example, the IAB node can report that the antenna panel used by the MT of the IAB node when receiving a certain downlink reference signal set is co-located with a certain antenna panel of the DU. It should be noted that it is assumed here that the remaining signals transmitted and received by the MT (e.g., physical uplink shared channel (PUSCH) and physical downlink shared channel (PDSCH)) have a spatial quasi-co-location (QCL) relationship with at least one downlink reference signal set, or use the same antenna panel.

[0096] Exemplarily, the second node may configure the resource reuse type for the first node with reference to the resource reuse type reported by the first node, for example:

[0097] When the resource multiplexing type reported by the first node is full-duplex multiplexing (here, if the first node supports full-duplex multiplexing, it can be assumed that the first node also supports all other resource multiplexing types), the second node can be configured with TDM, dynamic SDM, semi-static SDM and full-duplex;

[0098] When the resource reuse type reported by the first node is semi-static SDM, the second node can be configured with TDM, dynamic SDM, or semi-static SDM;

[0099] When the resource reuse type reported by the first node is dynamic SDM, the second node can be configured with TDM and dynamic SDM;

[0100] When the first node reports the resource reuse type as TDM, the second node can configure TDM. As a possible implementation, after receiving the resource reuse type reported by the first node, the second node can also configure the resource reuse type for the first node using other methods without referring to the content reported by the first node. This is not limited to this.

[0101] Optionally, the above resource multiplexing types have different capability requirements. "Capability" includes one or more of the following: transmit-receive isolation, antenna isolation, and interference suppression capability, etc. Generally, the capability requirements of IAB nodes for different resource multiplexing types are in the following order: TDM < dynamic SDM < static SDM < full-duplex. That is, full-duplex requires higher transmit-receive isolation (or higher antenna isolation, and even higher interference suppression capability), while TDM requires lower transmit-receive isolation (or lower antenna isolation, or lower interference suppression capability). After the first node reports the supported resource multiplexing type to the second node, the resource multiplexing type configured by the second node for the first node should have the same or lower capability requirements. For example, after the first node reports that the supported resource multiplexing type of one or more antenna panels of its DU and MT is static SDM, the resource multiplexing type configured by the second node for it can be static SDM, dynamic SDM or TDM, but not full-duplex.

[0102] Optionally, the second node may configure a special type of soft resource for the first node. When the first node performs a handover or re-accesses, the first node may use the special soft resource to communicate with the upper node on the corresponding MT resource, for example, to receive a PDSCH or a physical downlink control channel (PDCCH) used to carry a random access response (RAR) message.

[0103] S230: The first node uses resources of one or more antenna panels of the second functional unit to transmit data, wherein the resource type of the one or more antenna panels of the second functional unit is determined according to the resource multiplexing type.

[0104] In an embodiment of the present application, the second node sends a resource reuse type to the first node via first indication information. This resource reuse type refers to a different resource reuse type between each of the multiple antenna panels of the first functional unit and the second functional unit. After obtaining this resource reuse type, the first node can combine the resource configuration of the first functional unit to determine the resources of one or more antenna panels of the second functional unit, and finally use the resources of one or more antenna panels of the second functional unit for data transmission, thereby implementing resource configuration in the IAB node for multiple antenna panels or multiple cells.

[0105] In one implementation, the DU of the first node can use all antenna panels, and the MT can use one antenna panel. Different antenna panels of the DU and the MT can have different resource multiplexing types. For example, when the antenna panel of the MT is the same as one antenna panel in the DU, the resource multiplexing type of the MT and the antenna panel of the DU can be TDM or dynamic SDM. For another example, when the antenna panel of the MT is different from one antenna panel in the DU, the resource multiplexing type of the MT and the antenna panel of the DU can be semi-static SDM or full-duplex. Figure 3 In the example scenario description, for antenna panel 0 and antenna panel 1, antenna panel 0 is shared by the MT and DU, and the resource multiplexing type of antenna panel 0 of the MT and DU is time division multiplexing TDM; while antenna panel 1 is only used by the DU. Therefore, the resource multiplexing type of antenna panel 1 of the DU and the MT can be TDM or semi-static SDM.

[0106] It should be understood that the above description is based on an example in which an MT uses one antenna panel, and does not limit the present invention. In other words, the MT may also receive or transmit data on different antenna panels. For example, the MT supports receiving data on multiple antenna panels, or the MT uses multiple antenna panels for mobility measurement or beam training.

[0107] Optionally, the second node may further send resource configuration information about the first functional unit to the first node, so that the first node may determine the resource configuration of one or more antenna panels of the second functional unit based on the resource configuration information of the first functional unit. Before the first node determines the resource configuration of the one or more antenna panels of the second functional unit, the method 200 further includes:

[0108] S240: The second node sends resource configuration information to the first node, where the resource configuration information indicates resources of one or more antenna panels of a first functional unit in the first node. Correspondingly, the first node receives the resource configuration information.

[0109] The first node determines the resources of one or more antenna panels of the second functional unit according to the resource multiplexing type indicated in the first indication information, the resources of one or more antenna panels of the first functional unit, and a preset relationship.

[0110] Specifically, the second node can send the resource configuration information to the first node through semi-static signaling (such as RRC signaling) or an interface message (such as F1-AP or an F1-AP interface message enhanced by an interface message). The first node can obtain the resources of one or more antenna panels of the first functional unit in the first node through the resource configuration information. Then, the first node determines the resources of one or more antenna panels of the second functional unit based on the resource multiplexing type indicated in the first indication information, the resources of the one or more antenna panels of the first functional unit, and the preset relationship.

[0111] The preset relationship includes a correspondence between the resource configuration of the first functional unit and the resource configuration of the second functional unit of the first node under different resource reuse types. Here, under different resource reuse types, the resource configuration of the DU and the resource configuration of the MT have different correspondences.

[0112] The embodiments described in this application can also be applied to the case where both the MT and the DU have multiple subunits.

[0113] The multiple subunits of the MT and the multiple subunits of the DU may have different multiplexing types, which are as described in the above embodiment. The multiplexing type may be reported by the first node to the second node, or configured by the second node for the first node.

[0114] For example, in one possible implementation, the second node configures a resource type for each MT subunit of the first node. The MT resource type includes at least one of available and unavailable. The first node and / or its superior node derives the resource type of each DU subunit based on the reuse relationship between the MT subunit and the DU subunit. The DU resource type includes at least one of hard resources, soft resources, and unavailable resources.

[0115] In another possible implementation, the second node configures the resource type of each sub-unit of the DU of the first node as hard resources or soft resources, and the first node and / or the upper node of the first node derives the availability of each resource of each MT sub-unit based on the multiplexing relationship between the MT sub-unit and the DU sub-unit.

[0116] It should be understood that the resource type configured by the second node for each MT and DU subunit of the first node may also include transmission direction, and the transmission direction includes downlink (denoted by D), uplink (denoted by U), and flexible (denoted by F).

[0117] Figure 4 The following diagram shows the corresponding relationship between the resource configuration of an antenna panel of DU and the resource configuration of MT under different resource reuse types. Figure 4The specific example in describes the preset relationship.

[0118] The first scenario: the resource multiplexing type is TDM.

[0119] In this case, the corresponding relationship between the resource configuration of an antenna panel of the DU and the resource configuration of the MT is as follows: for the hard resources of the DU, the corresponding resources of the MT are unavailable resources, that is, the MT will not communicate with the upper node on these resources; or, for the unavailable resources of the MT, the corresponding resources of the DU are hard resources. Figure 4 In the 10 time slots shown in FIG, in TDM, the resources corresponding to the DU in time slots 1 (DH), 3 (DH), 4 (DH), 5 (FH), 6 (FH), 7 (UH), and 8 (UH) are hard resources, and the MT resources corresponding to these time slots are unavailable resources. However, the MT resources corresponding to time slots 0 (the resources in the DU are unavailable (NULL) resources), 2 (the resources in the DU are downlink soft resources DS), and 9 (the resources in the DU are uplink soft resources US) are available resources.

[0120] It should be understood that Figure 4 The resource configuration of an antenna panel of a DU and the resource configuration of a MT in TDM are only some examples. The following lists all possible combinations of the resource configuration of an antenna panel of a DU and the resource configuration of a MT in the TDM scenario of the first node. Table 1 shows:

[0121] Table 1

[0122]

[0123]

[0124] In the above Table 1, "MT:Tx" indicates that the MT should transmit after being scheduled; "DU:Tx" indicates that the DU may transmit; "MT:Rx" indicates that the MT is capable of receiving (if there is a signal to be received); "DU:Rx" indicates that the DU may schedule the uplink transmission of the lower-level node; "MT:Tx / Rx" indicates that the MT should transmit or receive after being scheduled, but the transmission and reception do not occur at the same time; "DU:Tx / Rx" indicates that the DU may transmit or receive the transmission of the lower-level node, but the transmission and reception do not occur at the same time; "IA" indicates that the DU resources are explicitly or implicitly indicated as available; "INA" indicates that the DU resources are explicitly or implicitly indicated as unavailable; "MT:NULL" indicates that the MT does not transmit and does not have to have the receiving capability; "DU:NULL" indicates that the DU does not transmit and does not receive the transmission of the lower-level node.

[0125] The second scenario: the resource reuse type is static SDM.

[0126] In this case, the corresponding relationship between the resource configuration of an antenna panel of the DU and the resource configuration of the MT is as follows: when the DU and the MT are in the same transmission direction, for the hard resources of the DU, the corresponding resources of the MT are unavailable resources, that is, the MT will not communicate with the upper node on these resources; when the DU and the MT are in the opposite direction, for the hard resources of the DU, the corresponding resources of the MT are available resources. Alternatively, when the DU and the MT are in the same direction, for the unavailable resources of the MT, the corresponding resources of the DU are hard resources; when the DU and the MT are in the opposite direction, for the available resources of the MT, the corresponding resources of the DU can be hard resources. Figure 4 As shown in the figure, in static SDM, the resources corresponding to the DU in timeslots 1 (DH), 3 (DH), 4 (DH), 5 (FH), 6 (FH), 7 (UH), and 8 (UH) are hard resources. The MT resources corresponding to the MT in timeslots in the same transmission direction as the DU or in timeslots corresponding to flexible resources (including timeslots 1, 3, 5, 6, and 8) are unavailable resources. However, the MT resources corresponding to timeslot 0 (the resources in the DU are unavailable (NULL) resources), timeslot 2 (the resources in the DU are downlink soft resources DS), timeslot 4 (the resources in the DU are downlink hard resources DH), timeslot 7 (the resources in the DU are uplink soft resources US), and timeslot 9 (the resources in the DU are uplink soft resources US) are available resources. The resources corresponding to the MT in timeslots in the opposite direction of the DU (including timeslot 4) are available resources. It can be seen that for time slot 4, the resource configuration of DU and MT under different resource reuse types are different.

[0127] It should be understood that Figure 4 The resource configuration of a DU antenna panel and the resource configuration of the MT in the SDM scenario are only some examples. The following lists all possible combinations of the resource configuration of a DU antenna panel and the resource configuration of the MT in the SDM scenario for the first node, as shown in Table 2 below:

[0128] Table 2

[0129]

[0130]

[0131] The explanations or concepts of the terms appearing in Table 2 can be found in the descriptions in Table 1 and are not repeated here for the sake of brevity.

[0132] For example, when the resource type of a DU is F, according to Table 2, the upper node needs to know the specific transmission direction of the DU in advance before deciding whether to perform space division multiplexing transmission. To achieve this goal, the IAB node can report the transmission direction of the F resource in the DU in advance so that the upper node can schedule the DU.

[0133] Alternatively, in another possible implementation, when the IAB node is not configured to report the actual direction of the DU's F resources, when the DU's F resources are (explicitly or implicitly) configured as hard resources, no space division transmission is performed, and when the F resources are soft resources, dynamic SDM is performed, that is, only dynamic SDM is allowed for the DU's F resources.

[0134] The third scenario: the resource reuse type is full-duplex.

[0135] In this case, the transmission and reception of MT and DU can not affect each other, that is, the resource configuration of MT and the resource configuration of DU do not affect each other. Figure 4 As shown in , in a full-duplex scenario, the resources of the DU in each time slot can be hard resources, and the resources of the MT in each time slot can be available resources.

[0136] The fourth scenario: the resource reuse type is dynamic SDM.

[0137] The difference between dynamic SDM and static SDM is that whether DU and MT perform SDM depends on the scheduling or instruction of the second node, that is, spatial division multiplexing is only performed between the available resources of MT and the soft resources of DU. Figure 4 As shown in the figure, in dynamic SDM, the resources corresponding to the DU in timeslots 1 (DH), 3 (DH), 5 (FH), 6 (FH), 7 (UH), and 8 (UH) are hard resources. The MT resources corresponding to the MT in timeslots with the same transmission direction as the DU or in timeslots corresponding to flexible resources (including timeslots 1, 3, 5, 6, and 8) are unavailable resources. However, the MT resources corresponding to timeslot 0 (the resources in the DU are unavailable (NULL) resources), timeslot 2 (the resources in the DU are downlink soft resources DS), timeslot 4 (the resources in the DU are downlink soft resources DS), timeslot 7 (the resources in the DU are uplink soft resources US), and timeslot 9 (the resources in the DU are uplink soft resources US) are available resources. This differs from the DU resource configuration in static SDM in that, in dynamic SDM, the DU's resources in timeslot 4 are soft resources.

[0138] In one possible implementation, when the DU resource is F, only dynamic SDM can be performed. That is, the IAB node first determines the transmission direction of the corresponding MT resource, and then schedules the DU resource. The transmission on the DU resource determined by the IAB node can enable the DU and MT to send at the same time, or the DU and MT to receive at the same time. It should be understood that this is only based on Figure 4 The time slot in the embodiment is described as an example, but it does not limit the embodiments of the present application. In fact, the time slot can be replaced by other time domain resources, such as frames, subframes, micro time slots, symbols, etc.

[0139] It should also be understood that the technical solutions of the embodiments of the present application may not be limited to the above four situations, but may also be applicable to other resource multiplexing types, such as FDM (including static FDM and dynamic FDM, where the resource configuration of static FDM is the same as that of static SDM, and dynamic FDM is the same as that of dynamic SDM), and there is no limitation on this.

[0140] For the scenario of multiple antenna panels, with the above-mentioned preset relationship, after receiving the resources of one or more antenna panels of the first functional unit, the first node uses the preset relationship corresponding to the resource multiplexing type (for example, if the resource multiplexing type is TDM, then look up Table 1; if the resource multiplexing type is SDM, then look up Table 2) to determine the resources of one or more antenna panels of the second functional unit. Specifically, if the first functional unit is DU and the second functional unit is MT, and the second node sends the resource configuration of part or all of the antenna panels of the DU to the first node, then the first node obtains the resource multiplexing type of the antenna panels of the DU and the MT, and then uses the preset relationship corresponding to the resource multiplexing type to search, and can determine the resource configuration of the MT; or, if the first functional unit is MT and the second functional unit is DU, and the second node sends the resource configuration of part or all of the antenna panels of the MT to the first node, then the first node obtains the resource multiplexing type of the antenna panels of the MT and the DU, and then uses the preset relationship corresponding to the resource multiplexing type to search, and can determine the resource configuration of the DU.

[0141] Taking the example of a first functional unit being a DU and a second functional unit being an MT, assuming that the DU can use all antenna panels and the MT can only use one of multiple antenna panels, the first indication information can be used to indicate the resource multiplexing type between each of the multiple antenna panels of the DU and the MT. Different antenna panels of the DU can have different resource multiplexing types with the MT. The first node can determine the resource configuration of the MT based on the resource multiplexing type indicated in the first indication information and the resource configuration of the DU. For example, if the first indication information indicates that the resource multiplexing type between the DU's antenna panel 0 and the MT is TDM, the first node can obtain the resource configuration of the MT by searching Table 1 above. Alternatively, if the first indication information indicates that the resource multiplexing type between the DU's antenna panel 1 and the MT is SDM, the first node can obtain the resource configuration of the MT by searching Table 2 above. For example, if the resource multiplexing type between the DU's antenna panel 0 and the MT is TDM, if one of the time slots in the resources of the DU's antenna panel 0 is DL-H, then the MT resource is NULL according to Table 1.

[0142] Taking the first functional unit as MT and the second functional unit as DU as an example, assuming that DU can use all antenna panels and MT can only use one of multiple antenna panels, then the first indication information can be used to indicate the resource multiplexing type corresponding to the antenna panel of MT and each antenna panel of DU. The first node can determine the resource configuration of DU based on the resource multiplexing type indicated in the first indication information and the resource configuration of MT. For example, the first indication information indicates that the resource multiplexing type of antenna panel 0 of MT and DU is TDM. The first node can obtain the resource configuration of DU by looking up the above Table 1; or, the first indication information indicates that the resource multiplexing type of antenna panel 1 of MT and DU is SDM. The first node can obtain the resource configuration of DU by looking up the above Table 2. Figure 5 A schematic diagram showing the multiplexing type of one antenna panel of MT and two antenna panels of DU is shown. Figure 5 As shown, the resource multiplexing type of one antenna panel of MT and antenna panel 0 of DU is multiplexing type 0, and the resource multiplexing type of one antenna panel of DU is multiplexing type 1. Figure 5, the MT's resources need to be determined based on both the results derived from resource reuse type 0 and the results derived from resource reuse type 1. For example, if the first node determines that a resource of the MT is an available resource based on resource reuse type 0 and the resources of DU antenna panel 0, and determines that the resource of the MT is an unavailable resource based on resource reuse type 1 and the resources of DU antenna panel 1, the resource should ultimately be determined as an available resource. If the first node determines that the resource is an unavailable resource based on the resources of DU antenna panel 0 and resource reuse type 0, and also determines that the resource is an unavailable resource based on the resources of DU antenna panel 1 and resource reuse type 1, then the resource of the MT is an unavailable resource.

[0143] Figure 6 Given Figure 5 An example of a scenario. Figure 6 As shown, the MT resources are multiplexed with the resources of the DU's antenna panel 0 using TDM. The MT resources are multiplexed with the resources of the DU's antenna panel 1 using SDM. For timeslots 0, 1, 2, 3, 4, and 5, the MT resources are D, D, D, U, U, and U, respectively. The resources of the DU's antenna panel 0 are DS, DH, US, US, UH, and DS, respectively. The resources of the DU's antenna panel 1 are DS, DH, UH, US, UH, and DH, respectively.

[0144] The second node can configure resources for all different antenna panels of the DU of the first node. For example, the resource types may include DS, DH, US, UH, FH, FS, and NA. As for the resources of the MT, the first node can derive them based on the resource configurations of multiple antenna panels of the DU. For the same resource, different antenna panels of the DU may have different resource configurations. Figure 6 In the example, for the same uplink resource of the DU (corresponding to timeslot 2), the resource on antenna panel 0 is a soft resource and the resource on antenna panel 1 is a hard resource. The corresponding MT resource is a downlink resource (status is available). The MT's available resources are derived from the resource configuration of antenna panels 0 and 1 of the DU. In other words, the MT's available resources in timeslot 2 are the intersection of the MT resource available derived from antenna panel 0 of the DU and the MT resource available derived from antenna panel 1 of the DU.

[0145] Alternatively, the second node may configure some antenna panel resources for the DU of the first node. For example, the resource types may include DS, DH, US, UH, FH, FS, and NA. Exemplarily, the second node may configure the resources of the same antenna panel as the MT for the DU of the first node, so that the first node may deduce the resources of the MT based on the preset relationship and the resource reuse type. For the resources of other antenna panels, the first node may derive them based on the resource reuse type and the resources of the MT. Here, the derivation method of the first node may not be limited, as long as the derivation result satisfies the preset relationship under different resource reuse types. In Figure 6 In the example, if the second node configures the resources of the antenna panel 0 of the DU, the first node can deduce the resource configuration of the MT based on the resource multiplexing type (TDM) and the preset relationship. Furthermore, the resources of the antenna panel 1 of the DU can be derived based on the resources of the MT (whether available), the resource multiplexing type (SDM) and the preset relationship.

[0146] Alternatively, the second node may configure MT resources for the first node. The first node may obtain, based on the MT resource configuration and the resource reuse type of the DU using the same antenna panel as the MT, the resource configuration of the DU using the same antenna panel as the MT. Alternatively, based on the resource reuse type of the DU resources using a different antenna panel as the MT, the resource configuration of the DU resources using a different antenna panel as the MT may be obtained.

[0147] Therefore, no matter whether the resources first configured by the second node for the first node are MT resources or DU resources, the first node can deduce the corresponding resource configuration based on the preset relationship and resource reuse type.

[0148] The above describes an example in which the second node configures DU resources for the first node and derives MT resources, or derives DU resources for the first node. In practice, the second node can also configure resources for the first node in a full configuration manner. That is, the second node configures MT resources (including available resources and unavailable resources) and DU resources (including soft resources and hard resources) for the first node at the same time. Here, the first node no longer needs to derive resources based on the above preset relationship. However, the resource configuration of any antenna panel of the MT configured by the second node and the resource configuration of any antenna panel of the DU should satisfy the constraints of the resource configuration under the corresponding resource reuse type (that is, the above preset relationship).

[0149] The examples above (e.g. Figure 5 or Figure 6) describes an embodiment of multiple antenna panels of a DU of a first node and a single antenna panel of a MT. Optionally, the MT may also use multiple antenna panels. The following describes embodiments of multiple antenna panels of a DU and multiple antenna panels of a MT. It should be understood that terms or concepts such as resource reuse types and preset relationships involved in the following embodiments can be referred to in the previous description and will not be repeated here.

[0150] If the second node initially configures the resources of each antenna panel of the MT for the first node, the first node can determine the resources of each antenna panel of the DU based on the resources of each antenna panel of the MT and the preset relationship. Each antenna panel of the MT may be independently configured with a set of available resources, wherein the available resources of different antenna panels of the MT may be orthogonal in the time domain or spatial domain, or may overlap in the time domain or spatial domain, without limitation. Accordingly, the resource configuration results determined by the first node for the resource configuration of one antenna panel of the DU based on the resource configuration of different antenna panels of the MT may be different. Optionally, the first node may determine the DU resource based on the following principle: for a DU resource (e.g., a time slot or a symbol), if the results determined by the first node based on the resources and resource reuse types of different antenna panels of the MT are all hard resources, then the DU resource is a hard resource; if the results determined by the first node based on the resources and resource reuse type of one antenna panel in the MT are soft resources, that is, if the result of the DU resource derivation from any one of the multiple antenna panels in the MT is a soft resource, then the DU resource is a soft resource. That is, the soft resources of the DU are the union of the soft resources determined according to different antenna panels of the MT.

[0151] Similarly, if the second node initially configures the resources of each antenna panel of the DU for the first node, the first node can determine the resources of each antenna panel of the MT based on the resources of each antenna panel of the DU and the preset relationship. Of course, whether the resources of each antenna panel of the MT are available resources can be determined based on the derivation results of the multiple antenna panels of the DU.

[0152] Optionally, the first node may determine the MT resource based on the following principle: for an MT resource, if the first node determines that all the results determined based on the resources and resource reuse types of different antenna panels in the DU are unavailable resources, then the MT resource is an unavailable resource; if the first node determines that the result determined based on the resources and resource reuse type of one antenna panel in the DU is an available resource, that is, as long as one of the multiple antenna panels in the DU derives that the result of the MT resource is an available resource, then the MT resource is an available resource. In other words, the available resources of the MT are the union of the available resources determined based on the different antenna panels in the DU.

[0153] Optionally, the first node may also determine the MT resource based on the following principle: for an MT resource, if the first node determines that all the results determined based on the resources and resource reuse types of different antenna panels of the DU are available resources, then the MT resource is an available resource; if the first node determines that the result determined based on the resources and resource reuse type of one antenna panel in the DU is an unavailable resource, that is, as long as one of the multiple antenna panels or cells in the DU derives that the result of the MT resource is an unavailable resource, then the MT resource is an unavailable resource. In other words, the unavailable resources of the MT are the union of the unavailable resources determined based on the different antenna panels of the DU.

[0154] Figure 7 FIG. 1 is a schematic diagram showing an example of multiple antenna panels of a DU and multiple antenna panels of an MT. Figure 7 As shown, the resource multiplexing type of the MT's antenna panel 0 and the DU's antenna panel 0 is 00, and the resource multiplexing type of the MT's antenna panel 0 and the DU's antenna panel 1 is 01; the resource multiplexing type of the MT's antenna panel 1 and the DU's antenna panel 0 is 10, and the resource multiplexing type of the MT's antenna panel 1 and the DU's antenna panel 1 is 11. Figure 7 The resource reuse type in the diagram only schematically describes the possible combination relationship between different antenna panels. Of course, the specific resource reuse type can be found in the previous description, such as static SDM, dynamic SDM, TDM, full-duplex, etc., which will not be described here. Figure 7 In the example, the resources of DU antenna panel 0 need to be determined based on the results derived from resource reuse type 00 and resource reuse type 10. For example, if the first node determines that resource a of DU antenna panel 0 is a soft resource based on resource reuse type 00, and determines that resource a of DU antenna panel 0 is a hard resource based on resource reuse type 10, based on the principles for determining DU resources in the previous text, resource a should ultimately be determined as a soft resource. The resources of DU antenna panel 1 need to be determined based on the results derived from resource reuse type 01 and resource reuse type 11. For example, if the first node determines that resource b of DU antenna panel 1 is a hard resource based on resource reuse type 01, and determines that resource b of DU antenna panel 0 is a hard resource based on resource reuse type 11, based on the principles for determining DU resources in the previous text, resource b should ultimately be determined as a hard resource.

[0155] It should be understood that Figure 7 The examples are only for facilitating understanding by those skilled in the art and should not limit the scope of protection of the embodiments of the present application.

[0156] The above embodiments describe a method for a first node to derive a DU resource type based on an MT resource configuration, and a method for a first node to derive an MT resource type based on a DU resource configuration. Optionally, the above derivation method is also applicable to a superior node or host node of the first node. For example, the superior node or host node may use the above derivation method to derive a DU resource type based on the MT resource configuration of the first node, or may derive an MT resource type based on the DU resource configuration of the first node.

[0157] In the embodiments of the present application, to ensure the smooth transmission or reception of specific physical signals (such as broadcast synchronization signal blocks and reference signals), the resource configuration of the DU or MT can be adjusted to make the resource configuration of the IAB more flexible. This will be described in detail below. Of course, this adjustment is not limited to the scenario of multiple antenna panels, that is, the scenario of a single antenna panel is also applicable.

[0158] Optionally, the method 200 further includes:

[0159] If a signal to be transmitted exists in the DU or MT of the first node, the first node adjusts the resources in the resource configuration of the DU. The resources corresponding to the signal to be transmitted are first-category resources. The first-category resources are hard resources. This description uses the case of determining the resource configuration of a DU as an example.

[0160] The signal to be transmitted may be a synchronization signal (SS) / physical broadcast channel (PBCH) block (or referred to as a synchronization signal block SSB), or a random access channel (RACH). It should be understood that the SSB may include a set of SSBs sent by an IAB node to an access UE, or may include a set of SSBs used by IAB nodes for mutual discovery, without limitation. Similarly, the RACH channel may include a RACH sent by a UE or other IAB nodes to an IAB node.

[0161] The purpose of adjusting the resources in the DU's resource configuration is to ensure that the transmission and reception of the signal to be transmitted is always feasible. Specifically, if the MT has a signal to be transmitted and the corresponding resources in the DU are hard resources, the corresponding resources in the DU (i.e., hard resources) can be adjusted to ensure smooth transmission or reception of the signal to be transmitted in the MT. If the DU has a signal to be transmitted and the corresponding resources in the DU are soft resources or unavailable resources, the corresponding resources in the DU can be adjusted to hard resources to ensure smooth transmission or reception of the signal to be transmitted in the DU.

[0162] It should be understood that the embodiments of the present application do not specifically limit the granularity of resource adjustment. It can be a timeslot-level conversion, a symbol-level conversion, or the like. For example, timeslot-level conversion means that the resources corresponding to the entire timeslot containing the signal are converted to hard resources. Symbol-level conversion means that only the resources corresponding to the symbol containing the signal are converted to hard resources.

[0163] Optionally, if the DU has a signal to be transmitted, the first node adjusts the resource configuration of the DU, including:

[0164] If the first node determines that a first resource in the resource configuration of the DU is a second-category resource, the first node adjusts the first resource to a first-category resource. The first resource is a resource used by the DU of the first node to transmit the signal to be transmitted. The second-category resource is a soft resource or an unavailable resource.

[0165] The "adjustment" here means: converting soft resources or unavailable resources into hard resources. It should be understood that the "adjustment" here can be understood as being previously configured as soft resources or unavailable resources, but being used directly as hard resources in actual communication. That is, regardless of whether the first resource is a soft resource or an unavailable resource, the DU must transmit the signal to be transmitted in the first resource. It should be understood that the "adjustment" here may not require separate configuration information to adjust the resources, but rather means that the so-called "adjusted" resource position in actual use can break through the rules constrained by the above-mentioned preset relationship (such as the aforementioned Table 1 or Table 2) and use soft resources or unavailable resources as hard resources.

[0166] That is to say, if the above-mentioned signal to be transmitted exists in the DU of the first node, but in the time domain, the first resource used to transmit the signal to be transmitted is a soft resource or an unavailable resource, in order not to affect the sending or receiving of the signal to be transmitted in the DU, the first resource can be converted into a hard resource.

[0167] Optionally, if a signal to be transmitted exists in the DU of the first node, the first node adjusting resource configuration of the DU includes:

[0168] If the first node determines that the second resource in the resource configuration of the DU is a first-category resource, the first node adjusts the second resource to a second-category resource. The second resource is a resource that overlaps in the time domain with a resource used to transmit the to-be-transmitted signal in the MT of the first node. The second resource is a resource in the DU. It should be understood that the overlap here refers to overlap in the time domain and is not limited to overlap in the frequency domain.

[0169] "Adjustment" here refers to converting hard resources into soft resources or unusable resources. It should be understood that "adjustment" here can be understood as previously configuring hard resources but directly using them as soft resources or unusable resources in actual communication. That is, regardless of whether the resource that overlaps with the second resource in the time domain is a hard resource or a soft resource (or unusable resource), the MT must transmit the signal to be transmitted in the second resource. It should be understood that "adjustment" here does not require separate configuration information to adjust resources. Instead, it means that in actual use, the so-called "adjusted" resource location can break away from the constraints of the aforementioned preset relationship (e.g., Table 1 or Table 2), allowing the hard resource to be used as a soft resource or unusable resource.

[0170] That is to say, if the MT in the first node has the above-mentioned signal to be transmitted, and in the time domain, the resource used to transmit the signal to be transmitted corresponds to the second resource in the DU but is a hard resource. In order not to affect the sending or receiving of the signal to be transmitted in the MT, the second resource can be converted into a soft resource or an unavailable resource, that is, the signal transmission of the DU in the second resource needs to be stopped.

[0171] For ease of understanding, the following Figure 8 The following example illustrates this. Figure 8 As shown, Figure 8 The upper middle figure shows the resource allocation before and after DU adjustment; Figure 8 The lower middle figure shows the resource configuration before and after MT adjustment. Figure 8 The R in represents a signal, such as SSB or RACH. Taking the adjustment of DU resource configuration as an example, it can be seen that the period of DU resource configuration is 10 resource units (including 5 resource units corresponding to hard resources and 5 resource units corresponding to soft resources), while the signal transmission period is 40 resource units. When receiving or sending this signal, multiple signal resources may overlap with the soft resources of DU in the time domain. If you want to configure the periodic transmission or reception of the DU to completely overlap with the hard resources in the time domain, you need to make the configuration period of the DU resource configuration (including soft resources and hard resources) equal to the transmission period of the signal. For example, assuming that this signal is SSB, the period of SSB can be 160 milliseconds (ms), which can include 640 time slots (60KHz subcarrier spacing). Increasing the period of DU resource configuration will greatly increase the signaling overhead.

[0172] To avoid increasing overhead, the resources of the DU can be adjusted. Figure 8The adjusted DU resource configuration is shown in Figure 2. By adjusting the soft resources in the DU that overlap with multiple signal resources in the time domain to hard resources, the smooth transmission of the DU periodic signal is ensured, thereby avoiding an increase in signaling overhead. For example, the resources used by the DU to transmit SSBs or receive RACHs may overlap with the DU's soft resources (e.g., overlap in the time domain). The DU's soft resources can be adjusted to hard resources. Alternatively, the resources used by the MT to receive SSBs or transmit RACHs may overlap with the MT's unavailable resources (e.g., overlap in the time domain). The MT's unavailable resources can be adjusted to available resources.

[0173] The above describes Figure 8 It should be understood that the resource configuration of MT can refer to the above method to adjust the unavailable resources to available resources. For the sake of brevity, how to adjust the resource configuration of MT is not described here. It should also be understood that Figure 8 The description is based on the example that the period of resource configuration of MT is the same as the period of resource configuration of DU. However, the embodiment of the present application does not limit whether the period of resource configuration of DU is the same as the period of resource configuration of MT. They can be the same or different.

[0174] That is, the resources used to send SSBs (e.g., DU resources) should essentially be hard resources; or the resources used to receive RACHs (DU resources) should essentially be hard resources. As another possible scenario, if the resources used to receive SSBs (or send RACHs) in the MT resources overlap in the time domain with the resources used to send SSBs (or receive RACHs) in the DU resources, then the SSBs in the MT resources can be received (or sent RACHs) preferentially. That is, the resources used to send SSBs (or receive RACHs) in the corresponding DU resources are considered soft resources or unavailable resources.

[0175] The above describes the situation where the resource configuration of the DU needs to be adjusted. It should be understood that for other periodically sent or received signals, such as reference signals such as CSI-RS signals that the IAB node requests the upper node to configure, the resource configuration determined in the previous article can be used for corresponding sending or receiving without adjusting the resource configuration of the DU.

[0176] It should also be understood that the above describes a situation where the resource configuration of the DU needs to be adjusted. In one possible implementation, the resource configuration of the MT can also be adjusted. For example, if there is a high-priority signal in the DU that needs to be transmitted, and the resources corresponding to the MT's resource configuration (available resources) overlap in the time domain, then the corresponding MT's resources can be adjusted to unavailable resources to ensure smooth transmission of the signal in the DU. For example, the resources for the DU to send SSB or receive RACH may overlap in the time domain with the MT's available resources. In this case, the MT's available resources can be adjusted to unavailable resources, that is, the upper node does not schedule the MT of the IAB node at the corresponding location to transmit signals such as PDSCH and PUSCH.

[0177] It should be understood that Figures 4 to 8 The examples are only for the convenience of those skilled in the art to understand the embodiments of the present application, and are not intended to limit the embodiments of the present application to the specific scenarios illustrated.
