[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0035] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, although these technologies can also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0036] Figure 1 A schematic diagram of a wireless communication system applicable to the embodiments of the present application is shown. The wireless communication system includes a terminal 11, an IAB node 12, a parent IAB node 13, and a centralized control unit (CU) 14.

[0037] In the above system, IAB node 12 can rely on the MT to find its parent IAB node 13 and establish a wireless connection with the DU of the parent IAB node 13. This wireless connection is called the backhaul link of IAB node 12 and becomes the access link of the parent IAB node 13. After the backhaul link is fully established, IAB node 12 enables its DU function, and the DU will provide cell services, that is, the DU can provide access services to terminal 11. The DUs of all IAB nodes can connect to CU 14.

[0038] In addition, if Figure 2As shown, the CU can configure the DU of the IAB node through the F1-C (F1-AP) protocol. The CU can configure the MT of the IAB node through the Radio Resource Control (RRC) protocol. The CU 14 can be a donor node (donor IAB node) or a separate network node, specifically including: CU-control plane (CP) and CU-user plane (UP).

[0039] It should be noted that Figure 1 The terminal 11 , the IAB node 12 , the parent IAB node 13 and the CU 14 are merely used as examples for illustration. In actual applications, the embodiment of the present application does not limit the number of IAB nodes.

[0040] In addition, the terminal 11 can also be referred to as a terminal device or user equipment (UE). The terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), a RedCap UE, and other terminal-side devices. Among them, the RedCap UE may include: wearable devices, industrial sensors, video surveillance equipment, etc. Wearable devices include: bracelets, headphones, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application.

[0041] The resource configuration method, device, network node and storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0042] See Figure 3 , Figure 3 This is a flow chart of a resource configuration method provided by an embodiment of the present application. Figure 3 As shown, the following steps are included:

[0043] Step 301: The IAB node obtains frequency domain resource information;

[0044] The frequency domain resource information is used to indicate available frequency domain resources of the DU of the IAB node.

[0045] The IAB node may obtain frequency domain resource information by receiving frequency domain resource information configured by a parent node or CU, or may obtain predefined frequency domain resource information. The parent node of the IAB node is the previous hop node of the IAB node, or the first N hop nodes of the IAB node.

[0046] The available frequency domain resources may refer to the frequency domain resource range of the DU. This frequency domain resource range may include the actual frequency domain resources occupied by the DU's actual transmission. For example, it may also include frequency domain resources not occupied by the DU's actual transmission. In other words, it may be a frequency domain range that is optional for the DU, and the frequency domain range for the DU's actual transmission is a subset of the available frequency domain resources. Alternatively, the available frequency domain resources may refer to the actual frequency domain resources occupied by the DU's actual transmission.

[0047] In addition, the above-mentioned available frequency domain resources may be available frequency domain resources implicitly or explicitly indicated by the above-mentioned frequency domain resource information.

[0048] In the embodiment of the present application, the above steps can be used to configure available frequency domain resources for the DU of the IAB node, thereby improving the accuracy of resource configuration, that is, available frequency domain resources can be configured for the DU as a unit, thereby improving the configuration effect of configuring resources for the IAB node.

[0049] As an optional implementation manner, the frequency domain resource information includes at least one of the following:

[0050] The first frequency domain resource information configured by the parent node for the IAB node

[0051] Second frequency domain resource information configured by the CU for the IAB node;

[0052] The third frequency domain resource information predefined by the protocol.

[0053] The parent node may be the previous hop of the IAB node, or may be a node N hops above the IAB node, where N is an integer greater than 1, that is, there may be other IAB nodes between the parent node and the IAB node.

[0054] The parent node may configure the frequency domain resource information through a medium access control element (MAC CE) or downlink control information (DCI) signaling, or may configure the frequency domain resource information through RRC signaling of a CU.

[0055] The above CU can configure frequency domain resource information through F1-C or RRC signaling.

[0056] In addition, the resource of the protection frequency domain interval of the MT and DU of the IAB node may also be defined by protocol.

[0057] In this implementation, available frequency domain resources may be configured for the IAB DU in a variety of ways.

[0058] Optionally, when the IAB node obtains at least two of the first frequency domain resource information, the second frequency domain resource information and the third frequency domain resource information, the available frequency domain resources are the available frequency domain resources indicated by the frequency domain resource information determined in the at least two items according to the first signaling.

[0059] The above-mentioned first signaling can be an additional indication signaling other than the above-mentioned frequency domain resource information, for example: one signaling configures the above-mentioned frequency domain resource information, and another signaling indicates one of the at least two items. The signaling indicates the use of one of the at least two items, for example: indicating the use of frequency domain resource information predefined by the parent node, CU or protocol to determine the available frequency domain resources, such as 1 bit or 2 bits for indication.

[0060] As an optional implementation manner, the available frequency domain resources are indicated by the parent node or CU through the frequency domain resource information.

[0061] The above indication may be through configuration or dynamic indication, and the indication method may be explicit or implicit.

[0062] For example: indicating that the available frequency domain range of the DU is the carrier bandwidth of the DU; another example: indicating that the frequency domain resources (including all, part or none) in the carrier bandwidth of the DU are the available frequency domain resources of the DU, so that the granularity of the indication can be smaller than the carrier bandwidth; another example: indicating that a certain / certain carriers of the DU are the available frequency domain resources of the DU, so that the granularity of the indication can be the carrier bandwidth, and dynamic carrier activation or deactivation can be introduced based on the carrier configuration, so that some duplexing modes can be switched on and off through frequency domain indication.

[0063] As an optional implementation manner, the available frequency domain resources are related to at least one of the following:

[0064] The frequency domain resource information indicates an available frequency domain range of the DU;

[0065] The frequency domain resource information indicates the carrier bandwidth of the DU;

[0066] The carrier bandwidth of the DU of the parent node;

[0067] The available frequency domain range of the DU of the parent node;

[0068] The working bandwidth of the MT of the IAB node;

[0069] Guard interval.

[0070] The working bandwidth of the MT may be the BWP of the MT, or part of the frequency domain resources within the BWP of the MT. The BWP of the MT includes one or more BWPs configured by the IAB MT, or one or more activated BWPs.

[0071] The guard interval may be a guard interval between the working bandwidths of the DU and the MT.

[0072] For example, the available frequency domain resources include at least one of the following:

[0073] The available frequency domain range of the DU is the remaining frequency domain resources minus at least one of the carrier bandwidth of the DU of the parent node and the available frequency domain range of the DU of the parent node;

[0074] The available frequency domain range of the DU is obtained by excluding at least one of the carrier bandwidth of the DU of the parent node and the available frequency domain range of the DU of the parent node, and the remaining frequency domain resources after excluding the guard interval;

[0075] The available frequency domain range of the DU is the remaining frequency domain resources minus the working bandwidth of the MT of the IAB node;

[0076] The available frequency domain range of the DU is the remaining frequency domain resources minus the working bandwidth of the MT of the IAB node and the guard interval;

[0077] The frequency domain resources remaining after deducting at least one of the carrier bandwidth of the DU of the parent node and the available frequency domain range of the DU of the parent node from the carrier bandwidth of the DU;

[0078] The carrier bandwidth of the DU is excluding at least one of the carrier bandwidth of the DU of the parent node and the available frequency domain range of the DU of the parent node, and the frequency domain resources remaining after excluding the guard interval;

[0079] The frequency domain resources remaining from the carrier bandwidth of the DU minus the working bandwidth of the MT of the IAB node;

[0080] The carrier bandwidth of the DU is the frequency domain resource remaining after deducting the working bandwidth of the MT of the IAB node and the guard interval.

[0081] Here, "remove" means that some resources are excluded.

[0082] Among them, the frequency domain resources remaining after removing at least one of the carrier bandwidth of the DU of the parent node and the available frequency domain range of the DU of the parent node from the available frequency domain range of the above-mentioned DU can be the available frequency domain range of the DU - the available frequency domain range of the DU of the parent node, or the available frequency domain range of the DU - the carrier bandwidth of the DU of the parent node, or the available frequency domain range of the DU - the available frequency domain range of the DU of the parent node - the carrier bandwidth of the DU of the parent node.

[0083] The available frequency domain range of the above-mentioned DU excluding at least one of the carrier bandwidth of the DU of the parent node and the available frequency domain range of the DU of the parent node, and the frequency domain resources remaining after excluding the protection interval can be the available frequency domain range of the DU - the available frequency domain range of the DU of the parent node - the protection interval, or the available frequency domain range of the DU - the carrier bandwidth of the DU of the parent node - the protection interval, or the available frequency domain range of the DU - the available frequency domain range of the DU of the parent node - the carrier bandwidth of the DU of the parent node - the protection interval.

[0084] It should be noted that other implementations can also refer to the above description, which are not listed here one by one. In addition, if the two resources have no overlapping parts, no exclusion operation is required.

[0085] In this implementation, at least one of the above items can be used to flexibly configure the available frequency domain resources of the DU, and can also reduce interference between the MT and the DU.

[0086] As an optional implementation manner, the available frequency domain resources and the working bandwidth of the MT of the IAB node have at least one of the following relationships:

[0087] The available frequency domain resources include frequency domain resources affected by the working bandwidth of the MT;

[0088] The available frequency domain resources include the working bandwidth of the MT;

[0089] There is resource overlap between the available frequency domain resources and the working bandwidth of the MT;

[0090] The available frequency domain resources are located within the working bandwidth of the MT.

[0091] The frequency domain resources affected by the working bandwidth of the MT may be obtained based on a fixed MT working bandwidth for an available frequency domain range of at least one of a physical downlink control channel (PDCCH), a search space, and a physical uplink control channel (PUCCH) of the DU. Alternatively, the frequency domain resources affected by the working bandwidth of the MT may be obtained based on an actual working bandwidth of the MT for an available frequency domain range of at least one of a physical downlink shared channel (PDSCH) and a physical uplink shared channel (PUSCH) of the DU.

[0092] The above-mentioned available frequency domain resources include the working bandwidth of the MT, which may be that the available frequency domain range of the DU includes the working bandwidth of the MT, and the above-mentioned available frequency domain resources are located within the working bandwidth of the MT, which may be that the working bandwidth / available frequency domain range of the DU is located within the working bandwidth / available frequency domain range of the MT.

[0093] The resource overlap between the available frequency domain resources and the working bandwidth of the MT may be:

[0094] The DU's working bandwidth / low frequency range / frequency domain resource with a lower number overlaps with the MT's working bandwidth / frequency domain range / frequency domain resource with a higher number; or

[0095] The DU's working bandwidth / high frequency of the available frequency domain range / resources with higher frequency domain resource numbers overlap with the MT's working bandwidth / frequency domain range's low frequency / resources with lower frequency domain resource numbers; or

[0096] The MT's operating bandwidth / low frequency range / frequency domain resource with a lower number overlaps with the DU's operating bandwidth / high frequency range / frequency domain resource with a higher number; or

[0097] The high frequency of the MT's working bandwidth / frequency domain range / resources with higher frequency domain resource numbers overlap with the low frequency of the DU's working bandwidth / available frequency domain range / resources with lower frequency domain resource numbers.

[0098] For example: Figure 4 As shown, the available frequency domain range of the DU includes the working bandwidth of the MT. The guard band may be outside the working bandwidth of the MT or within the working bandwidth of the MT. Figure 4 Take the case where the guard interval is outside the MT working bandwidth as an example.

[0099] Another example: Figure 5 As shown, the low frequency / frequency domain resource with a lower frequency domain resource number in the DU's working bandwidth / available frequency domain range overlaps with the high frequency / frequency domain resource with a higher frequency domain resource number in the MT's working bandwidth / frequency domain range. The guard interval can be outside or within the MT's working bandwidth. Figure 5 Take the case where the guard interval is outside the MT working bandwidth as an example.

[0100] Another example: Figure 6 As shown, the high frequency / higher frequency domain resource numbered resources of the DU's working bandwidth / available frequency domain range overlap with the low frequency / lower frequency domain resource numbered resources of the MT's working bandwidth / frequency domain range. The guard interval can be outside or within the MT's working bandwidth. Figure 6 Take the case where the guard interval is outside the MT working bandwidth as an example.

[0101] Another example: Figure 7 As shown, the working bandwidth / available frequency domain range of the DU is within the working bandwidth / frequency domain range of the MT.

[0102] Another example: Figure 8 As shown, the low frequency / frequency domain resource with a lower number in the working bandwidth / frequency domain range of the MT overlaps with the high frequency / frequency domain resource with a higher number in the working bandwidth / available frequency domain range of the DU.

[0103] Another example: Figure 9 As shown, the high frequency / frequency domain resource with a higher number in the working bandwidth / frequency domain range of the MT overlaps with the low frequency / frequency domain resource with a lower number in the working bandwidth / available frequency domain range of the DU.

[0104] As an optional implementation manner, the available frequency domain resources are related to a multiplexing mode of the IAB node.

[0105] The multiplexing methods include frequency division multiplexing (FDM), space division multiplexing (SDM) and time division multiplexing (TDM).

[0106] Furthermore, the method for acquiring the above-mentioned frequency domain resource information may also be related to the multiplexing method.

[0107] In this implementation, FDM, SDM or TDM multiplexing is achieved through the above-mentioned available frequency domain resources.

[0108] For example, when FDM multiplexing is supported, the IAB node does not expect the available frequency domain range of the IAB DU to overlap with the operating bandwidth of the IAB MT. In other words, the CU / parent node configures the available frequency domain resources of the IAB DU to not overlap with the operating bandwidth of the IAB MT. Specifically, FDM multiplexing can be achieved through the explicit or implicit configuration described above.

[0109] For example, when SDM multiplexing is supported, the available frequency domain range of the IAB DU can overlap with the operating bandwidth of the IAB MT. The DU and MT multiplex in the overlapping frequency domain resources. Additionally, additional indication signaling can be used to indicate whether the DU can use the overlapping portion. If not, the DU and MT switch back to FDM resource multiplexing; otherwise, they use SDM resource multiplexing. Alternatively, the DU can be instructed to use some of the overlapping resources.

[0110] In one embodiment, the IAB node may report whether the IAB DU uses the portion of the available frequency domain range of the IAB DU that completely overlaps with the working bandwidth of the IAB MT, or uses part of the overlapping resources, so that the parent node or CU can determine whether SDM multiplexing actually exists in the overlapping portion, thereby assisting the parent node or CU in resource management or scheduling.

[0111] Optionally, in a case where the IAB node supports FDM, the frequency domain resource information is further used to indicate that the available frequency domain resources can be used as FDM multiplexing resources.

[0112] In this implementation, since the available frequency domain resources are indicated as FDM multiplexing resources, potential SDM multiplexing can be indicated in advance before the available frequency domain resources of the IABDU overlap with the working bandwidth of the IAB MT, thereby preparing for the switching of the bandwidth part (BWP) to improve the switching efficiency.

[0113] Optionally, when the IAB node supports SDM, the frequency domain resource information is further used to indicate that the available frequency domain resources can be used as SDM multiplexing resources.

[0114] Since the indicated available frequency domain resources can be used as SDM multiplexing resources, it is possible to indicate potential FDM multiplexing in advance before the available frequency domain resources of the IAB DU overlap with the working bandwidth of the IAB MT, thereby preparing for the switching of the BWP and improving the switching efficiency.

[0115] As an optional implementation, the method further includes:

[0116] The IAB node reports expected information to the parent node or CU, where the expected information includes at least one of the following:

[0117] A desired multiplexing mode and frequency domain resources corresponding to at least one multiplexing mode.

[0118] The desired multiplexing mode may be FDM, SDM, or TDM.

[0119] The frequency domain resources corresponding to the at least one multiplexing mode may be at least one of a size and a position of the frequency domain resources corresponding to each multiplexing mode.

[0120] In this implementation, since the above-mentioned expected information is reported, the resource configuration information finally obtained can be easily matched with the above-mentioned expectation, thereby ultimately improving the working performance of the IAB node.

[0121] In addition, in the embodiment of the present application, the CU may notify the IAB node of the multiplexing mode, for example, directly notifying the IAB node, or notifying the IAB node through a parent node.

[0122] As an optional implementation, the available frequency domain resources are related to the duplex mode of the IAB node, and the duplex mode includes: the duplex mode supported on the DU cell of the IAB node, or the duplex mode between the DU cell of the IAB node and at least one MT serving cell.

[0123] In an embodiment of the present application, the MT may support dual connectivity, such as multiple MT cells corresponding to one DU cell. The duplex mode between the DU cell and at least one MT serving cell may be such that the DU cell corresponds to a different duplex mode when corresponding to the MT serving cell, and different DU available frequency domain resources may be configured.

[0124] Optionally, available frequency domain resources associated with different duplex modes are acquired independently.

[0125] In this implementation, the available frequency domain resources of the DU can be independently acquired or notified for different duplex modes. It should be noted that the different duplex modes here do not refer to all duplex modes, because in some scenarios, it is not ruled out that some duplex modes do not need to acquire or notify the available frequency domain range of the DU.

[0126] Optionally, the multiplexing mode of the DU of the IAB and the MT is related to the duplex mode.

[0127] The above correlation may include at least one of the following:

[0128] When MT transmission (MT TX) and DU transmission (DU TX) occur simultaneously, or when MT TX and DU TX are supported to occur simultaneously, the frequency domain resources of MT TX and DU TX may overlap. Supporting simultaneous MT and DU transmission does not require that the MT and DU must transmit signals at the same time. Simultaneous occurrence may mean that they are required to exist at the same time during actual scheduling.

[0129] When MT reception (MT RX) and DU reception (DU RX) occur simultaneously, or when MT RX and DU RX are supported to occur simultaneously, the frequency domain resources of MT RX and DU RX can overlap;

[0130] When MT TX and DU RX occur simultaneously or when MT TX and DU RX are supported to occur simultaneously, the frequency domain resources of MT TX and the frequency domain resources of DU RX may overlap. In this case, the default IAB node may support full-duplex. Alternatively, the frequency domain resources of MT TX and the frequency domain resources of DU RX do not overlap. In this case, the default IAB node may not support full-duplex.

[0131] When MT RX and DU TX occur simultaneously or when MT RX and DU TX are supported to occur simultaneously, the frequency domain resources of MT RX may overlap with the frequency domain resources of DU TX. In this case, the default IAB node may support full-duplex. Alternatively, the frequency domain resources of MT RX and the frequency domain resources of DU TX do not overlap. In this case, the default IAB node may not support full-duplex.

[0132] If the IAB node supports full-duplex (or supports MT TX and DU RX occurring simultaneously, or MT RX and DU TX occurring simultaneously), the frequency domain range of the IAB DU may overlap with the frequency domain range of the IAB MT.

[0133] As an optional embodiment, the method further includes at least one of the following:

[0134] The IAB node reports the available frequency domain resources to the parent node;

[0135] The IAB node reports the acquisition method of the frequency domain resource information to the parent node.

[0136] The above acquisition method may also be understood as a notification method in which a parent node or a CU notifies frequency domain resource information.

[0137] In this implementation, since the available frequency domain resources and at least one of the above-mentioned acquisition methods are reported to the parent node, the parent node can control at least one of the BWP and resource scheduling of the IAB MT according to the available frequency domain range of the IAB DU, so as to realize the FDM and SDM multiplexing mode between the MT and the DU, or ensure that the frequency domain resource interval used by the DU and the MT meets the guard interval.

[0138] In one embodiment, the CU may notify the parent node of the available frequency domain range of the DU of the IAB node, and / or the CU may notify the parent node of the method for obtaining / notifying the available frequency domain range of the IAB DU. In this embodiment, the parent node may also control at least one of the BWP and resource scheduling of the IAB MT based on the available frequency domain range of the IAB DU, to implement FDM and SDM multiplexing between the MT and the DU, or to ensure that the frequency domain resource interval used by the DU and the MT meets the guard interval.

[0139] As an optional implementation manner, in the case where the DU of the parent node does not schedule frequency domain resources, the available frequency domain resources are autonomously determined by the IAB node.

[0140] This implementation allows the IAB node to autonomously determine the appropriate use of certain frequency domain resources when the parent node (e.g., its IAB-DU) does not schedule them, thereby reducing transmission overhead. For example, the IAB node can determine the frequency domain range to be scheduled by the parent node for a period of time in the future based on the maximum or minimum Physical Resource Block (PRB) number recently scheduled by the parent node. The IAB node can then schedule the remaining frequency domain range of the carrier.

[0141] As an optional implementation manner, the frequency domain resource information includes scheduling of the parent node.

[0142] The above scheduling may be scheduling of MTs of the IAB node or scheduling of DUs of the IAB node.

[0143] In this implementation, it is possible to configure available frequency domain resources of the DU for the IAB node through scheduling by the parent node.

[0144] As an optional implementation,

[0145] The available frequency domain range of the DU of the above-mentioned IAB node configured by the CU through F1-C signaling on the symbol corresponding to at least one of the PDCCH, search space, control resource set, and PUCCH of the MT of the above-mentioned IAB node is obtained based on a fixed MT working bandwidth; or

[0146] The available frequency domain range of the DU of the IAB node configured by the parent node through DCI signaling on the symbol corresponding to at least one of the PDSCH and PUSCH of the MT of the IAB node is obtained based on the actual working bandwidth of the MT; or

[0147] The available frequency domain range of the DU of the above-mentioned IAB node configured by the parent node through DCI signaling, excluding the symbols corresponding to the PDCCH, search space, control resource set, and PUCCH of the MT of the above-mentioned IAB node, is obtained based on the actual working bandwidth of the MT.

[0148] As an optional implementation manner, the frequency domain resource information includes a first scheduling by the parent node to the MT of the IAB, and the available frequency domain resources are determined based on the first scheduling.

[0149] In this embodiment, it is possible to determine the available frequency domain resources of the DU based on the scheduling of the MT, for example, by implicitly indicating the available frequency domain range of the DU of the IAB node using the PDSCH or PUSCH (for example, DCI) that schedules the MT. One way may be to redefine the reserved bit in the PDCCH for indication. If the indication is set, the frequency domain range that the parent node will not schedule in the future period of time can be determined as the available frequency domain resources of the DU based on the frequency domain range scheduled by the PDCCH; or a predefined code point or code point combination is used as a setting. If the indication is a predefined code point or code point combination, the frequency domain range that the parent node will not schedule in the future period of time can be determined as the available frequency domain resources based on the frequency domain range scheduled by the PDCCH.

[0150] In this implementation, since the frequency domain resource information includes the first scheduling of the parent node to the MT of the IAB, there is no need to use additional signaling to obtain available frequency domain resources, thereby reducing transmission overhead.

[0151] Optionally, the available frequency domain resources include:

[0152] A first available frequency domain resource determined based on the center of the frequency domain range of the first scheduling; or

[0153] The second available frequency domain resources are determined based on the frequency domain range of the first scheduling.

[0154] In one embodiment, when the distance between the center of the frequency domain range and the lowest frequency domain resource of the bandwidth part BWP of the MT is less than the distance from the highest frequency domain resource of the BWP, the first available frequency domain resource includes or belongs to the frequency domain resource between the highest frequency domain resource of the BWP and the upper boundary of the frequency domain range.

[0155] Among them, the first available frequency domain resources include the frequency domain resources between the highest frequency domain resources of the BWP and the upper boundary of the frequency domain range, indicating that the range of the first available frequency domain resources is greater than or equal to the frequency domain resources between the highest frequency domain resources of the BWP and the upper boundary of the frequency domain range; the first available frequency domain resources belong to the frequency domain resources between the highest frequency domain resources of the BWP and the upper boundary of the frequency domain range, indicating that the range of the first available frequency domain resources is less than or equal to the frequency domain resources between the highest frequency domain resources of the BWP and the upper boundary of the frequency domain range.

[0156] In one embodiment, when the distance between the center of the frequency domain range and the highest frequency domain resource of the bandwidth part BWP of the MT is less than the distance from the lowest frequency domain resource of the BWP, the first available frequency domain resource includes or belongs to the frequency domain resource between the lowest frequency domain resource of the BWP and the lower boundary of the frequency domain range. The first available frequency domain resource includes the frequency domain resource between the lowest frequency domain resource of the BWP and the lower boundary of the frequency domain range, indicating that the range of the first available frequency domain resource is greater than or equal to the frequency domain resource between the lowest frequency domain resource of the BWP and the lower boundary of the frequency domain range; the first available frequency domain resource belongs to the frequency domain resource between the lowest frequency domain resource of the BWP and the lower boundary of the frequency domain range, indicating that the range of the first available frequency domain resource is less than or equal to the frequency domain resource between the lowest frequency domain resource of the BWP and the lower boundary of the frequency domain range.

[0157] In one implementation manner, the second available frequency domain resources include frequency domain resources outside the frequency domain range.

[0158] For example, if the center PRB of the frequency domain range scheduled by the IAB-DU of the parent node is closer to the lowest frequency domain resource of the MT BWP, it is determined that the parent IAB-DU will not use the frequency domain range from the highest frequency domain resource of the MT BWP to the upper boundary of the scheduled frequency domain range for a period of time in the future, thereby determining the first available carrier frequency resource to include or belong to the frequency domain range;

[0159] For another example, if the center PRB of the frequency domain range scheduled by the IAB-DU of the parent node is closer to the highest frequency domain resource of the MT BWP, it is determined that the parent IAB-DU will not use the frequency domain range from the lowest frequency domain resource of the MT BWP to the lower boundary of the scheduled frequency domain range for a period of time in the future, thereby determining the above-mentioned second available carrier frequency resource to include or belong to the frequency domain range;

[0160] For another example: the DU of the above-mentioned IAB node may use frequency domain resources outside the frequency domain range scheduled by the parent node's IAB-DU;

[0161] As an optional implementation manner, the frequency domain resource information includes a second scheduling of the DU of the IAB by the parent node, and the available frequency domain resources are determined based on the second scheduling.

[0162] In this embodiment, available frequency domain resources can be configured for the DU of the above IAB node through scheduling. For example, the PDSCH or PUSCH sent by the parent node to schedule the MT is only used to reserve the frequency domain resource range of the DU of the parent IAB.

[0163] As an optional implementation manner, the effective time of the available frequency domain resources is configured by the CU or the parent node.

[0164] In this implementation, the configuration of the available frequency domain resources can be implemented to take effect only within the above-mentioned effective time, so as to further enhance the control over the available frequency domain resources of the DU.

[0165] Optionally, the CU or parent node configures the effective time through at least one of the following indication parameters:

[0166] Period indication, time domain offset, and time domain resource size.

[0167] For example, the CU or parent node may send at least one of the above-mentioned indication parameters to the above-mentioned IAB node to configure the above-mentioned effective time. Specifically, the above-mentioned indication parameter may be configured through at least one of F1-C signaling, RRC signaling, Backhaul Adaptation Protocol control packet data unit (BAP control PDU), and DCI. In addition, the indication granularity may be: M time slots, N symbols, L milliseconds, K subframes, or A frames, etc., where M, N, L, K, A >= 1.

[0168] In addition, in the embodiment of the present application, the effective time of at least one of the working bandwidth of the MT of the IAB node and the protection band of the IAB node may also be configured.

[0169] Optionally, when the available frequency domain resources are independently configured for the first duplex mode, the available frequency domain resources are valid only during the time when the first duplex mode is adopted within the effective time.

[0170] The first duplex mode may be a predefined duplex mode, which is not limited.

[0171] This implementation can ensure that, during the effective time, the available frequency domain resources are valid only when an IAB node operates in the first duplex mode, thereby further enhancing the control over the available frequency domain resources of the DU.

[0172] As an optional implementation manner, when at least one of the time domain indication and the frequency domain indication of the IAB time-frequency resource indicates that the time-frequency resource is unavailable, the time-frequency resource is unavailable; or

[0173] The time-frequency resource of the IAB is available when at least one of a time domain indication and a frequency domain indication indicates that the time-frequency resource is available.

[0174] The above-mentioned time-frequency resources may be a collection of time domain resources and frequency domain resources.

[0175] In the case where at least one of the time domain indication and the frequency domain indication of the time domain resource of the IAB indicates that the time-frequency resource is unavailable, the unavailability of the time-frequency resource may be:

[0176] For the above-mentioned time-frequency resource, if both the time domain indication and the frequency domain indication indicate that the resource is unavailable, then the resource is unavailable; or

[0177] For the above time-frequency resources, if either the time domain indication or the frequency domain indication indicates that the resource is unavailable, then the resource is unavailable.

[0178] When at least one of the time domain indication and the frequency domain indication of the time domain resource of the above-mentioned IAB indicates that the time-frequency resource is available, the available time-frequency resource may be:

[0179] For the above-mentioned time-frequency resource, if both the time domain indication and the frequency domain indication indicate that the resource is available, then the resource is available; or

[0180] For the above-mentioned time-frequency resources, if either the time domain indication or the frequency domain indication indicates that the resource is available, then the resource is available.

[0181] In this implementation, by configuring the time domain resources to be available or unavailable in the above manner, flexible indication of time-frequency domain resources can be achieved.

[0182] The following example illustrates the configuration signaling of the available frequency domain resources for the DU of the IAB node:

[0183] The above CU can configure frequency domain resource information through F1-C or RRC signaling.

[0184] In one approach, the CU configures available frequency domain resources for the DU through F1-C signaling. Specifically, the F1-C signaling can explicitly configure the frequency domain starting position and frequency domain resource length indication. For example, the F1-C signaling can include the following configuration:

[0185] Frequency configuration item:

[0186] >Starting PRBs

[0187] >Number of PRBs

[0188] Among them, Starting PRBs is the starting position in the frequency domain;

[0189] Number of PRBs is an indication of the frequency domain resource length;

[0190] In another embodiment, the F1-C signaling may include the following configuration:

[0191] Frequency configuration item:

[0192] >BW ENUMERATED(BwofCarrier,BwofparentDU,BwofBWP)

[0193] Among them, BwofCarrier refers to the carrier bandwidth;

[0194] BwofparentDU refers to the bandwidth of the parent IAB's DU;

[0195] BwofBWP refers to the bandwidth of the MT of the above IAB;

[0196] In this manner, the CU may semi-statically configure the relationship between the available frequency domain resources of the DU and other bandwidths.

[0197] In another way, the CU can choose to explicitly configure or implicitly configure the frequency domain starting position and frequency domain resource length indication. The F1-C signaling may include the following configurations:

[0198]

[0199] In another approach, the CU may configure available frequency domain resources related to the multiplexing method. The signaling may include the following configurations:

[0200] Frequency configuration item:

[0201] >FDM ENUMERATED(BW1,BW2,BW3)

[0202] >SDM ENUMERATED(BW1,BW2,BW3)

[0203] >TDM ENUMERATED(BW1,BW2,BW3)

[0204] BW1 is the configured first frequency domain resource bandwidth; the frequency domain resource bandwidth may include at least one of the carrier bandwidth, the bandwidth of the parent IAB DU, and the BWP ranges of the IAB and MT. The available frequency domain resources for the IAB DU may be: carrier bandwidth minus the bandwidth of the parent IAB DU; or the available frequency domain resources for the IAB DU may be: carrier bandwidth minus the bandwidth of the parent IAB DU – N; carrier bandwidth – the bandwidth of the IAB MT BWP; or the available frequency domain resources for the IAB DU may be one of: carrier bandwidth minus the bandwidth of the IAB MTBWP – N, where N is the guard interval.

[0205] BW2 is the second configured frequency domain resource bandwidth; this frequency domain resource bandwidth may include at least one of the carrier bandwidth, the bandwidth of the parent IAB DU, and the BWP range of the IAB's MT. The available frequency domain resources for the IAB DU may be: carrier bandwidth minus the bandwidth of the parent IAB DU; or the available frequency domain resources for the IAB DU may be: carrier bandwidth minus the bandwidth of the parent IAB DU – N; carrier bandwidth minus the bandwidth of the IAB MT BWP; or carrier bandwidth minus the bandwidth of the IAB MT BWP – N.

[0206] BW3 is the configured third frequency domain resource bandwidth; the frequency domain resource bandwidth may include at least one of the carrier bandwidth, the carrier bandwidth, the bandwidth of the parent IAB DU and the BWP range of the IAB MT; the available frequency domain resources of the IAB DU may be: carrier bandwidth - the bandwidth of the parent IAB DU; or the available frequency domain resources of the IAB DU may be: carrier bandwidth - the bandwidth of the parent IAB DU - N; carrier bandwidth - the bandwidth of the IAB MT BWP; or the available frequency domain resources of the IAB DU may be: carrier bandwidth - the bandwidth of the IABMT BWP - one of N.

[0207] It should be noted that the configurations of the above-mentioned BW1, BW2 and BW3 may be the same or different, and there is no limitation on this.

[0208] It should be noted that the above only takes three bandwidth parameters as an example, and is not limited to the optional configuration of three bandwidths. The actual optional number is an integer greater than or equal to 1.

[0209] Alternatively, the CU may configure available frequency domain resources related to the duplex mode. For example, the duplex information element (multiplexing info IE) of the signaling may include the following configuration:

[0210]

[0211]

[0212] Among them, BW1, BW2, BW3 and BW4 are optional and may include at least one of the carrier bandwidth, the bandwidth of the DU of the parent IAB and the BWP range of the MT of the IAB; the available frequency domain resources of the DU of the IAB may be: carrier bandwidth - bandwidth of the parent IAB DU; or the available frequency domain resources of the DU of the IAB may be: carrier bandwidth - bandwidth of the parent IAB DU - N; or the available frequency domain resources of the DU of the IAB may be: or carrier bandwidth - bandwidth of the IAB MT BWP; or the available frequency domain resources of the DU of the IAB may be: carrier bandwidth - bandwidth of the IAB MT BWP - N.

[0213] It should be noted that the above description is made using CU configuration as an example. In the embodiment of the present application, the parent node may also refer to the above signaling to configure available frequency domain resources for the DU of the IAB node.

[0214] In this embodiment of the present application, an IAB node obtains frequency domain resource information, wherein the frequency domain resource information is used to indicate the available frequency domain resources of the DU of the IAB node. This can allocate frequency domain resources to the DU, thereby improving the accuracy of resource configuration and further improving the configuration effect of resources for the IAB node.
