Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority from Chinese Patent Application No. 202011141262.1, filed in China on October 22, 2020, the entire contents of which are incorporated herein by reference.

[0002] The present application belongs to the field of communication technology, and specifically relates to an information transmission method, an information transmission device, an electronic device, and a readable storage medium. [Background technology]

[0003] The IAB (integrated access backhaul) system is a technology for which NR Rel-16 has begun to formulate standards. The introduction of the IAB system is intended to address the situation where wired transmission network deployment is insufficient when access points are densely deployed. In other words, when there is no wired transmission network, access points can rely on wireless backhaul.

[0004] Figure 1 is a schematic diagram of the structure of an IAB system, where an IAB node includes a Distributed Unit (DU) and a Mobile Termination (MT). Once an IAB node establishes a complete backhaul link, the IAB node turns on its DU function, and the DU provides cell service, i.e., the DU can provide access service for the User Equipment (UE). An access point (i.e., IAB node) relies on the MT to find an upstream access point (parent IAB node) and establish a wireless connection with the DU of the upstream access point; this wireless connection is called a backhaul link. A self-backhaul circuit includes a donor IAB node (or IAB donor), which has a directly connected wired transmission network.

[0005] Figure 2 shows the CU-DU (Centralized Unit-Distributed Unit) structure of an IAB system. In a self-backhaul network, the DUs of all IAB nodes are connected to a single CU node, which configures the DUs via the F1-AP (F1 Application Protocol) protocol and configures the MTs via the RRC (Radio Resource Control) protocol.

[0006] The network structure of NR-DC (New Radio Dual Connectivity) for a UE (User Equipment) is shown in Figures 3 and 4, respectively, and the network structure of NR-DC for an IAB node is shown in Figures 5 and 6, respectively. Here, the MT of the UE or IAB node establishes a connection with two service DUs (i.e., DU1 and DU2), respectively. The upstream network structure has two different situations: one situation is that the MN (Master gNodeB) and the SN (Secondary gNodeB) are controlled by the same CU (Figures 3 and 5), and the other situation is that the MN and the SN are controlled by different CUs (Figures 4 and 6), where the MN is an MgNB or MCG donor, and the SN is an SgNB or SCG donor.

[0007] In applying a UE or IAB node to an NR-DC network, the inventors have discovered that the conventional technology has at least the following problems:

[0008] The MT of the UE or IAB node has limitations on multiplexing scheduling. When the MN and SN are controlled by different CUs, if resource allocation is not coordinated, a situation will arise in which there is a resource allocation conflict between the MCG link and the SCG link, which will cause scheduling from the MN and SN to collide with each other, resulting in transmission errors or resource unavailability. Summary of the Invention [Problem to be solved by the invention]

[0009] An object of the embodiments of the present application is to provide an information transmission method, an information transmission device, an electronic device, and a readable storage medium that can solve the problem in the related art that transmission errors occur or resources are unavailable due to resource allocation collisions when an MN and an SN are controlled by different CUs.

[0026] The following clearly and completely describes the technical solutions in the embodiments of the present application, in conjunction with the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative efforts fall within the scope of protection of the present application.

[0027] The terms "first," "second," etc. in the specification and claims of this application are intended to distinguish between similar objects and are not intended to describe a particular order or sequence. It should be understood that such terms, when used, are interchangeable where appropriate, so that embodiments of this application may be performed in orders other than those illustrated or described herein. Note that "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the related objects.

[0028] The following describes in detail the information transmission method, information transmission device, electronic device and readable storage medium according to the embodiments of the present application through specific embodiments and application scenarios in conjunction with the drawings.

[0029] FIG. 7 shows a structural schematic diagram of a self-backhaul dual-connection system according to an embodiment of the present application, where the self-backhaul dual-connection system includes: The system includes a first centralization unit 702, a second centralization unit 704, a wireless node 706, a first service node 708, and a second service node 710. Here, the wireless node 706 establishes connections with two service DUs (i.e., the first service node 708 and the second service node 710), respectively, and in the upstream network structure, the service nodes are controlled by different CUs, specifically, the first service node 708 is controlled by the first centralization unit 702, and the second service node 710 is controlled by the second centralization unit 704.

[0030] It should be noted that the downstream networks of the first concentrator unit 702 and the second concentrator unit 704 may each be connected to multiple service nodes, and the downstream of the radio node 706 may further be connected to multiple sub-nodes.

[0031] The radio node 706 may be a UE, and accordingly, the first service node 708 is an MgNB (Master gNodeB), and the second service node 710 is an SgNB (Secondary gNodeB), and the radio node 706 may be an IAB node including a DU and an MT, and accordingly, the first service node 708 is an MCG donor (Master Cell Group), and the second service node 710 is an SCG donor (Secondary Cell Group). The connection between the radio node 706 and the first service node 708 is called an MCG link, and the connection with the second service node 710 is called an SCG link.

[0032] From the perspective of air interface carrier allocation, there are several cases for the MCG link and SCG link of the self-backhaul dual-connection system according to the embodiment of the present application:

[0033] Case 1: The MCG link and SCG link use different carriers in different frequency bands. Case 2: The MCG link and SCG link use different carriers in the same frequency band. Case 3: The MCG link and the SCG link use the same carrier in the same frequency band.

[0034] The 3GPP (3rd Generation Partnership Project) supports NR-DC, in which the MCG link and the SCG link use different carriers. Under this premise, in case 1, the wireless node 706 can support unlimited multiplexing scheduling between the MCG link and the SCG link. On the other hand, in case 2, there are some restrictions on multiplexing scheduling between the MCG link and the SCG link in some cases. For example, if the frequencies of the carriers of the MCG link and the SCG link are similar and sufficient frequency isolation is not provided, the wireless node 706 cannot perform receive / transmit operations on the MCG link and transmit / receive operations on the SCG link at the same time. However, if the frequencies of the carriers of the MCG link and the SCG link provide sufficient frequency isolation, this restriction does not apply. The frequency isolation here may be determined by the magnitude of the frequency difference between the carriers. In case 3, the restrictions on multiplexing scheduling between the MCG link and the SCG link are greatest, and the wireless node 706 cannot perform receive / transmit operations on the MCG link and transmit / receive operations on the SCG link at the same time.

[0035] As mentioned above, the wireless node 706 has the limitation of multiplexing scheduling. When the MN and the SN are controlled by different centralized units, if resource allocation is not coordinated, a situation will occur in which resource allocation conflicts occur between the MCG link and the SCG link. Specifically, the following situations are included:

[0036] (1) Uplink and downlink configuration conflict: When the MCG link and the SCG link use different carriers in the same frequency band, or when the MCG link and the SCG link use the same carrier in the same frequency band, the first centralization unit 702 configures one slot of the first service node 708 as available for uplink, and the second centralization unit 704 configures the same slot of the second service node 710 as available for downlink. When the SN and MN simultaneously schedule the wireless node 706 to transmit in this slot, the wireless node 706 cannot support simultaneous transmission and reception, which will result in unpredictable behavior and the inability to transmit signaling or data immediately.

[0037] (2) Simultaneous scheduling / transmission collision: When the MCG link and the SCG link use the same carrier in the same frequency band, the wireless node 706 can transmit only one PUCCH (Physical Uplink Control Channel), PUSCH (Physical Uplink Shared Channel), or PDSCH (Physical Downlink Shared Channel) in the same slot on one carrier. If the MN and SN respectively place PUCCHs in the same slot or respectively schedule PUSCHs and PDSCHs simultaneously, the wireless node 706 cannot support simultaneous transmission and reception, resulting in unpredictable behavior and the inability to transmit signaling or data immediately.

[0038] In order to solve the problem of transmission errors or resource unavailability caused by resource allocation collisions when a MN (MgNB or MCG donor) and a SN (SgNB or SCG donor) are controlled by different CUs, an embodiment of the present application proposes a resource allocation coordination method for a self-backhaul dual-connection system, where the flow of resource allocation coordination between a first centralized unit and a second centralized unit is shown in Figure 8. After receiving a measurement report from a wireless node regarding its surrounding wireless nodes, the first centralized unit determines to add a second service node to the wireless node, and the second service node is controlled by the second centralized unit. Here, the measurement report may include signal quality from the second service node to the wireless node.

[0039] When the first centralization unit sends a second service node addition request to the second centralization unit, it also sends resource allocation coordination request information for the first service node DU and the second service node DU. Based on the coordination request information, the second centralization unit determines the DU resource allocation available to this radio node by the second service node, and sends the resource allocation to the second service node through sending context configuration information, thereby reducing or avoiding a situation where, when the second service node becomes the SN of this radio node, scheduling conflicts between the first service node and the second service node for this radio node, and the radio node MT cannot ensure that scheduling between the first service node and the second service node is performed correspondingly.

[0040] Optionally, the second centralized unit transmits resource allocation information of the second service node DU available for this radio node MT scheduling to the first centralized unit via additional feedback information via RRC signaling, and the first centralized unit rearranges the resource allocation information of the first service node DU available for this radio node MT scheduling based on this information, thereby reducing or avoiding cases where scheduling conflicts occur between the first service node and the second service node for this radio node.

[0041] Furthermore, the first centralized unit sends additional feedback of the second service node DU to the first service node, the first service node sends additional feedback of the second service node DU to the wireless node, and finally, the wireless node feeds back relocation completion information to the second centralized unit after executing the configuration message carried in the additional feedback of the second service node DU.

[0042] After the resource allocation coordination between the first centralized unit and the second centralized unit is performed, the first centralized unit and the second centralized unit may respectively configure the first service node DU and the second service node DU using DU resource allocation signaling to schedule the wireless node. For example, in an IAB network, resources for the DU at each hop may be semi-statically allocated by the CU, and the DU schedules the child IAB-MT based on the allocated resources. Here, resource allocation is determined by combining TDD (Time Division Duplexing) allocation and resource type indication.

[0043] The TDD configuration indicates uplink fixed slots and OFDM (Orthogonal Frequency Division Multiplexing) symbols, flexible uplink (flexible) slots and OFDM symbols, and downlink fixed slots and OFDM symbols. The resource type indicates the availability attribute of the resource, and the availability attribute includes hard (hard available), NA (Not Available), and soft (soft available).

[0044] Here, hard is a DU resource with one DU indication that is hard, and this DU can be freely used according to the link direction (connection direction) of the TDD configuration, and soft is a DU resource with one DU indication that is soft, and this DU can be freely used according to the link direction of the TDD configuration when it determines that its parent IAB-DU is not in use.

[0045] In addition, resources can be dynamically shared between the previous hop and next hop of an IAB node, and for the soft resources of an IAB-DU, the IAB node can determine whether the IAB-DU can schedule the soft resources for transmission at the next hop without affecting the reception of the IAB-MT. Based on current 3GPP protocols, a parent IAB-DU can use PDCCH to indicate to a child IAB node whether the soft resources of the subnode IAB-DU are available, and an IAB node can also determine by itself whether to schedule the soft resources for data transmission / reception at the next hop without affecting the reception of the IAB-MT when scheduling the soft resources.

[0046] It should be noted that the resource configuration may include frequency domain resource allocation of the DU, and here only TDD configuration is taken as an example.

[0047] Alternatively, if the resource coordination between the first centralized unit and the second centralized unit is insufficient or not coordinated, and the wireless node MT finds that the transmission resources scheduled by the first service node DU and the second service node DU collide with each other, it may report the collision information to the first centralized unit, the second centralized unit, the first service node, or the second service node, and the first centralized unit, the second centralized unit, the first service node, or the second service node will decide how to avoid the collision.

[0048] FIG. 9 shows one of the flowcharts of the information transmission method according to the embodiment of the present application, which includes: Step 902: a first centralized unit determines resource allocation coordination information; Step 904 may include a first centralized unit sending a first message carrying resource allocation coordination information to a second centralized unit.

[0049] In this embodiment, the first centralization unit determines resource allocation coordination information for the first service node DU of the wireless node and the second service node DU of the wireless node, and then transmits the resource allocation coordination information to the second centralization unit, so that the second centralization unit allocates resources for the second service node added to the wireless node based on the resource allocation coordination information. This reduces or avoids the situation where, when the second service node becomes the SN of this wireless node, scheduling conflicts between the first service node and the second service node for this wireless node, causing the wireless node to be unable to ensure that scheduling between the first service node and the second service node is performed correspondingly, thereby improving scheduling efficiency for the wireless node.

[0050] In some embodiments of the present application, the wireless node includes an IAB node or a UE, where the IAB node includes an MT and a DU. That is, the method of the embodiments of the present application can be applied to a method for coordinating resource allocation between two parent IAB-DUs when the two parent IAB-DUs belong to different CUs in the case of same-frequency DC or same-frequency-band different-frequency DC of an IAB network, and this method can also be applied to dual connectivity of an NR / LTE UE under the same conditions. According to the embodiments of the present application, resource allocation conflicts and scheduling conflicts between the MCG link and SCG link of a UE or MT can be reduced or avoided.

[0051] In some embodiments of the present application, the resource allocation coordination information includes at least one of: a time-frequency resource of a distributed unit of a wireless node; a time-frequency resource of a first service node for scheduling the wireless node; a required minimum time-frequency resource of the first service node for scheduling the wireless node; a time-frequency resource pool of a second service node for scheduling the wireless node; a multiplexing scheduling scheme between the first service node connecting link and the second service node connecting link for scheduling the wireless node; a duplex mode between the first service node connecting link and the second service node connecting link for scheduling the wireless node; a link direction corresponding to the time-frequency resource; and a type indication of the time-frequency resource, where the type information of the time-frequency resource includes hard available, soft available, and unavailable.

[0052] In this embodiment, the resource allocation cooperation information between the first service node DU and the second service node DU transmitted from the first centralized unit to the second centralized unit includes: (1) The time domain and frequency domain resources of the DU of the IAB node; (2) time domain resources and frequency domain resources of the DU for MT or UE scheduling of the IAB node of the first service node; (3) minimum required time domain resources and frequency domain resources of the DU for MT or UE scheduling of the IAB node of the first service node; (4) a time domain resource pool and a frequency domain resource pool available to the second centralized unit for allocating MT or UE scheduling available to the IAB node to the second service node DU; (5) A multiplexing scheduling method or duplex mode between the MN link and the SN link available for MT or UE scheduling of the IAB node, where the multiplexing scheduling method includes time division multiplexing, frequency division multiplexing, etc., and the duplex mode supports half duplex, full duplex, etc.; (6) Link directions corresponding to time domain resources and frequency domain resources, where the link directions of the time domain resources and frequency domain resources may be indicated by slots or OFDM symbols; (7) A type indication of the time-frequency resource, wherein the type information of the time-frequency resource may include one or more of: hard available, soft available, and unavailable.

[0053] For example, after a first centralized unit transmits time-frequency resources of DUs of an IAB node to a second centralized unit, the second centralized unit can determine resource allocation that avoids collisions with DU resources of the IAB node; after a first centralized unit transmits time-frequency resources of DUs for MT or UE scheduling of the IAB node of a first service node to a second centralized unit, the second centralized unit can determine DU resource allocation of the second service node that avoids collisions with DUs of the first service node; after a first centralized unit transmits a time-frequency resource pool available for the second centralized unit to allocate MT or UE scheduling available to the IAB node to a second service node DU, the second centralized unit can determine a DU resource range that can be allocated to the second service node for MT or UE scheduling of this IAB node.

[0054] By transmitting the above information to the second centralized unit, the second centralized unit can perform resource allocation for the second service node based on this information, thereby reducing or avoiding cases where conflicts occur between the first service node and the second service node in scheduling of MTs or UEs of IAB nodes.

[0055] FIG. 10 shows a schematic diagram of time-division allocation of resource allocation in an embodiment of the present application, in which after a second service node is added, some of the time domain resources for scheduling the radio nodes of the first service node before the second service node is added are allocated to the second service node, and some of the time domain resources are allocated to the second service node. This divides the time domain resources for scheduling the radio nodes of the first service node and the second service node so that they are different, thereby reducing or avoiding time domain resource collisions that occur when scheduling radio nodes.

[0056] FIG. 11 shows a schematic diagram of frequency division allocation of resource allocation in an embodiment of the present application, in which after a second service node is added, the frequency domain resources for scheduling the radio nodes of the first service node are all allocated to the frequency domain resources for scheduling the radio nodes of the first service node before the second service node is added, and a portion is allocated to the second service node, thereby dividing the frequency domain resources for scheduling the radio nodes of the first service node and the second service node so that the frequency domain resources are different, thereby reducing or avoiding frequency domain resource collisions that occur when scheduling radio nodes.

[0057] In Figures 10 and 11, resources marked with "↑" are fixed resources for the uplink, resources marked with "↓" are fixed resources for the downlink, and resources marked with "↓↑" are slot resources that change from the downlink to the uplink.

[0058] In some embodiments of the present application, the first centralization unit transmitting the first message carrying resource allocation coordination information to the second centralization unit includes the first centralization unit transmitting the first message carrying resource allocation coordination information to the second centralization unit when a second service node of the wireless node needs to be added.

[0059] In this embodiment, after receiving a measurement report from a wireless node regarding its surrounding wireless nodes (the measurement report may include the signal quality from the second service node to the wireless node), the first centralization unit decides to add a second service node to the wireless node, and then transmits resource allocation coordination information when sending an add request to the second centralization unit, i.e., the first message may be an add request sent by the first centralization unit to the second centralization unit to notify the second centralization unit of the addition of the second service node. According to the embodiment of the present application, the second centralization unit performs resource coordination for the second service node when adding the second service node, thereby reducing or avoiding resource conflicts when scheduling the wireless node between the second service node and the first service node.

[0060] In some embodiments of the present application, after step 904, the information transmission method further includes: the first centralization unit receiving a second message sent by the second centralization unit; the first centralization unit obtaining resource configuration information of the second service node of the wireless node carried in the second message; and the first centralization unit adjusting the resource configuration information of the first service node of the wireless node based on the resource configuration information of the second service node.

[0061] In this embodiment, the second centralization unit allocates resources for the second service node of the added wireless node based on the resource allocation coordination information, and then feeds back the resource allocation information of the second service node to the first centralization unit. The first centralization unit may further adjust the resource allocation information of the first service node based on the resource allocation information of the second service node, thereby better ensuring that the scheduling resources of the first service node for the wireless node and the scheduling resources of the second service node for the wireless node do not collide, and improving the success rate of scheduling for the wireless node.

[0062] In some embodiments of the present application, before step 902 or after step 904, the information transmission method further includes: a first consolidation unit receiving a third message transmitted by the wireless node; the first consolidation unit obtaining resource conflict information carried in the third message; and the first consolidation unit adjusting scheduling for the wireless node or determining resource allocation coordination information based on the resource conflict information.

[0063] In this embodiment, the wireless node may supplementarily coordinate the scheduling resources of the wireless nodes between the first service node and the second service node. Specifically, when the wireless node finds that the transmission resources scheduled by the first service node and the second service node collide with each other, it may report resource collision information to the first centralization unit, and the first centralization unit may then decide how to avoid the conflict.

[0064] It should be noted that the process of the wireless node auxiliary coordinating the scheduling resources of the wireless node between the first service node and the second service node may be performed by the wireless node auxiliary coordinating the scheduling resources of the wireless node between the first service node and the second service node before or after the first centralized unit transmits resource allocation coordination information to the second centralized unit, that is, when the resources between the first centralized unit and the second centralized unit are not coordinated or the coordination is insufficient.

[0065] Specifically, if the first centralized unit obtains the resource conflict information before step 902, the first centralized unit determines the resource allocation coordination information in combination with the resource conflict information, and if the first centralized unit obtains the resource conflict information after step 904, the first centralized unit adjusts the scheduling for the wireless node or re-determines the resource allocation coordination information based on the resource conflict information. The above method can reduce the scheduling collision probability for the wireless node.

[0066] In some embodiments of the present application, the resource conflict information includes at least one of a system frame number, a slot, or a symbol number, and resource conflict type information, where the resource conflict type information is: (1) Time domain overlap or frequency domain overlap of PDSCH (Physical Downlink Shared Channel), PDCCH (Physical Downlink Control Channel) or CSI-RS (Channel State Information-Reference Signal) transmission between a first service node link (i.e., MCG link) and a second service node link (i.e., SCG link); and (2) Time domain overlap or frequency domain overlap of PUSCH (Physical Uplink Shared Channel), SRS (Sounding Reference Signal), PUCCH (Physical Uplink Control Channel) or PRACH (Physical Random Access Channel) transmission between the first service node link and the second service node link; (3) time-domain or frequency-domain overlap between at least one of PUSCH, SRS, PUCCH, and PRACH transmissions of the first service node link and at least one of PDSCH, PDCCH, and CSI-RS transmissions of the second service node link; (4) time-domain or frequency-domain overlap between at least one of PUSCH, SRS, PUCCH, and PRACH transmissions of the second service node link and at least one of PDSCH, PDCCH, and CSI-RS transmissions of the first service node link; (5) At least one of a time domain overlap or a frequency domain overlap of DCI (Downlink Control Information) search spaces between the first service node link and the second service node link.

[0067] In this embodiment, if any of the above collision behaviors are detected, it indicates that the scheduling for the wireless node between the first service node and the second service node is colliding, and the wireless node reports one or more of the system frame number, slot, and symbol number of the collision burst and the collision type information to the first centralization unit, and the first centralization unit may decide how to avoid it, thereby reducing the probability of scheduling collision for subsequent wireless nodes.

[0068] In some embodiments of the present application, FIG. 12 shows a second flowchart of an information transmission method according to an embodiment of the present application, which includes: Step 1202, a first centralization unit receiving a third message transmitted by a wireless node; Step 1204, the first centralization unit obtains the resource conflict information carried in the third message; Step 1206 includes the first centralized unit adjusting scheduling for the wireless nodes or determining resource allocation coordination information based on the resource conflict information.

[0069] Here, the resource conflict information includes at least one of a system frame number, a slot, or a symbol number, and includes resource conflict type information, which is as described above and will not be further described here.

[0070] In this embodiment, the technical solution in which the first centralized unit adjusts scheduling for the wireless nodes or determines resource allocation coordination information based on the resource conflict information transmitted by the wireless nodes may be implemented independently of the technical solution in which the first centralized unit determines resource allocation coordination information and transmits the resource allocation coordination information to the second centralized unit, that is, the scheduling resources of the wireless nodes between the first service node and the second service node are coordinated solely by the wireless nodes. If the wireless nodes discover that the transmission resources scheduled by the first service node and the second service node conflict with each other, they may report the resource conflict information to the first centralized unit, and the first centralized unit may then determine how to avoid the conflict.

[0071] Specifically, the first centralized unit adjusts scheduling for the wireless nodes or determines resource allocation coordination information based on the resource conflict information, and through the above method, can reduce the scheduling conflict probability for the wireless nodes.

[0072] FIG. 13 shows a third flowchart of the information transmission method according to the embodiment of the present application, which includes: Step 1302, a second concentrator receives a first message sent by a first concentrator; Step 1304, a second centralization unit obtains resource allocation coordination information carried in the first message; Step 1306 may include the second centralization unit allocating resources for the second service node of the wireless node based on the resource allocation coordination information.

[0073] In this embodiment, the second centralization unit receives the resource allocation coordination information sent by the first centralization unit, and further allocates resources for the second service node added to the wireless node based on the resource allocation coordination information, thereby reducing or avoiding the situation where, when the second service node becomes the SN of this wireless node, the scheduling of the first service node and the second service node for this wireless node conflicts, causing the wireless node to be unable to ensure that the scheduling of the first service node and the second service node is performed correspondingly, thereby improving the scheduling efficiency for the wireless node.

[0074] In some embodiments of the present application, the wireless node includes an IAB node or a UE, where the IAB node includes an MT and a DU. That is, the method of the embodiments of the present application can be applied to a method for coordinating resource allocation between two parent IAB-DUs when the two parent IAB-DUs belong to different CUs in the case of same-frequency DC or same-frequency-band different-frequency DC of an IAB network, and this method can also be applied to dual connectivity of an NR / LTE UE under the same conditions. According to the embodiments of the present application, resource allocation conflicts and scheduling conflicts between the MCG link and SCG link of a UE or MT can be reduced or avoided.

[0075] In some embodiments of the present application, the resource allocation coordination information includes at least one of: a time-frequency resource of a distributed unit of a wireless node; a time-frequency resource of a first service node for scheduling the wireless node; a required minimum time-frequency resource of the first service node for scheduling the wireless node; a time-frequency resource pool of a second service node for scheduling the wireless node; a multiplexing scheduling scheme between the first service node connecting link and the second service node connecting link for scheduling the wireless node; a duplex mode between the first service node connecting link and the second service node connecting link for scheduling the wireless node; a link direction corresponding to the time-frequency resource; and a type indication of the time-frequency resource, where the type information of the time-frequency resource includes hard available, soft available, and unavailable.

[0076] In this embodiment, the resource allocation cooperation information between the first service node DU and the second service node DU transmitted from the first centralized unit to the second centralized unit includes: (1) The time domain and frequency domain resources of the DU of the IAB node; (2) time domain resources and frequency domain resources of the DU for MT or UE scheduling of the IAB node of the first service node; (3) minimum required time domain resources and frequency domain resources of the DU for MT or UE scheduling of the IAB node of the first service node; (4) a time domain resource pool and a frequency domain resource pool available to the second centralized unit for allocating MT or UE scheduling available to the IAB node to the second service node DU; (5) A multiplexing scheduling method or duplex mode between the MN link and the SN link available for MT or UE scheduling of the IAB node, where the multiplexing scheduling method includes time division multiplexing, frequency division multiplexing, etc., and the duplex mode supports half duplex, full duplex, etc.; (6) Link directions corresponding to time domain resources and frequency domain resources, where the link directions of the time domain resources and frequency domain resources may be indicated by slots or OFDM symbols; (7) A type indication of the time-frequency resource, wherein the type information of the time-frequency resource may include one or more of: hard available, soft available, and unavailable.

[0077] For example, after a first centralized unit transmits time-frequency resources of DUs of an IAB node to a second centralized unit, the second centralized unit can determine resource allocation that avoids collisions with DU resources of the IAB node; after a first centralized unit transmits time-frequency resources of DUs for MT or UE scheduling of the IAB node of a first service node to a second centralized unit, the second centralized unit can determine DU resource allocation of the second service node that avoids collisions with DUs of the first service node; after a first centralized unit transmits a time-frequency resource pool available for the second centralized unit to allocate MT or UE scheduling available to the IAB node to a second service node DU, the second centralized unit can determine a DU resource range that can be allocated to the second service node for MT or UE scheduling of this IAB node.

[0078] By transmitting the above information to the second centralized unit, the second centralized unit can perform resource allocation for the second service node based on this information, thereby reducing or avoiding cases where conflicts occur between the first service node and the second service node in scheduling of MTs or UEs of IAB nodes.

[0079] In some embodiments of the present application, after receiving a measurement report from a wireless node regarding its surrounding wireless nodes (the measurement report may include signal quality from a second service node to the wireless node), if the first centralization unit decides to add a second service node to the wireless node, the first centralization unit may send resource allocation coordination information when sending an add request to the second centralization unit, i.e., the first message may be an add request sent by the first centralization unit to the second centralization unit to notify the second centralization unit of the addition of the second service node. According to the embodiments of the present application, the second centralization unit performs resource coordination for the second service node when adding the second service node, thereby reducing or avoiding resource conflicts when scheduling the wireless node between the second service node and the first service node.

[0080] In some embodiments of the present application, after step 1306, the information transmission method further includes the second centralization unit sending a second message carrying resource configuration information of the second service node to the first centralization unit.

[0081] In this embodiment, after the second centralized unit allocates resources for the second service node of the added wireless node based on this resource allocation coordination information, the second centralized unit feeds back the resource allocation information of the second service node to the first centralized unit, so that the first centralized unit can further adjust the resource allocation information of the first service node based on the resource allocation information of the second service node, thereby better ensuring that the scheduling resources of the first service node for the wireless node and the scheduling resources of the second service node for the wireless node do not collide, and improving the success rate of scheduling for the wireless node.

[0082] In some embodiments of the present application, before step 1302 or after step 1304, the information transmission method further includes: a second concentrating unit receiving a fourth message transmitted by the wireless node; the second concentrating unit obtaining resource conflict information carried in the fourth message; and the second concentrating unit adjusting scheduling for the wireless node or allocating resources for the second service node based on the resource conflict information.

[0083] In this embodiment, the wireless node may supplementarily coordinate the scheduling resources of the wireless nodes between the first service node and the second service node. Specifically, when the wireless node finds that the transmission resources scheduled by the first service node and the second service node collide with each other, the wireless node may report resource collision information to the second centralization unit, and the second centralization unit may then decide how to avoid the conflict.

[0084] It should be noted that, through the process in which the wireless node auxiliary coordinates the scheduling resources of the wireless node between the first service node and the second service node, the second centralization unit may auxiliary coordinate the scheduling resources of the wireless node between the first service node and the second service node before or after receiving the resource allocation coordination information sent by the first centralization unit, i.e., when the resources between the first centralization unit and the second centralization unit are not coordinated or the coordination is insufficient, the wireless node may auxiliary coordinate the scheduling resources of the wireless node between the first service node and the second service node.

[0085] Specifically, if the second centralized unit obtains resource conflict information before step 1302, the second centralized unit adjusts scheduling for the wireless node or allocates resources for the second service node based on the resource conflict information, and further adjusts scheduling for the wireless node or reallocates resources for the second service node of the wireless node according to the resource conflict coordination information after receiving the resource allocation coordination information sent by the first centralized unit. If the second centralized unit obtains resource conflict information after step 1304, the second centralized unit adjusts scheduling for the wireless node or reallocates resources for the second service node based on the resource conflict information. The above scheme can reduce the scheduling collision probability for the wireless node.

[0086] In some embodiments of the present application, the resource conflict information includes at least one of a system frame number, a slot, or a symbol number, and resource conflict type information, where the resource conflict type information is: (1) Time domain overlap or frequency domain overlap of PDSCH (Physical Downlink Shared Channel), PDCCH (Physical Downlink Control Channel) or CSI-RS (Channel State Information-Reference Signal) transmission between the first service node link and the second service node link; (2) Time domain overlap or frequency domain overlap of PUSCH (Physical Uplink Shared Channel), SRS (Sounding Reference Signal), PUCCH (Physical Uplink Control Channel) or PRACH (Physical Random Access Channel) transmission between the first service node link and the second service node link; (3) time-domain or frequency-domain overlap between at least one of PUSCH, SRS, PUCCH, and PRACH transmissions of the first service node link and at least one of PDSCH, PDCCH, and CSI-RS transmissions of the second service node link; (4) time-domain or frequency-domain overlap between at least one of PUSCH, SRS, PUCCH, and PRACH transmissions of the second service node link and at least one of PDSCH, PDCCH, and CSI-RS transmissions of the first service node link; (5) At least one of a time domain overlap or a frequency domain overlap of DCI (Downlink Control Information) search spaces between the first service node link and the second service node link.

[0087] In this embodiment, if any of the above collision behaviors is detected, it indicates that the first service node and the second service node are scheduling a collision for the wireless node, and the wireless node may report one or more of the system frame number, slot, and symbol number of the collision burst and collision type information to the second centralization unit, which then determines how to avoid the collision, thereby reducing the probability of scheduling a collision for subsequent wireless nodes.

[0088] In some embodiments of the present application, FIG. 14 shows a fourth flowchart of an information transmission method according to an embodiment of the present application, which includes: Step 1402, a second centralization unit receiving a fourth message transmitted by a wireless node; Step 1404, the second centralization unit obtains the resource conflict information carried in the fourth message; Step 1406 includes the second centralization unit adjusting scheduling for the wireless node or allocating resources for the second service node based on the resource conflict information.

[0089] Here, the resource conflict information includes at least one of a system frame number, a slot, or a symbol number, and includes resource conflict type information, which is as described above and will not be further described here.

[0090] In this embodiment, the technical solution in which the second centralized unit adjusts scheduling for the wireless nodes or allocates resources for the second service nodes based on the resource conflict information transmitted by the wireless nodes may be implemented independently of the technical solution in which the second centralized unit allocates resources for the second service nodes based on the resource allocation coordination information transmitted by the first centralized unit, that is, the scheduling resources of the wireless nodes between the first service node and the second service node are coordinated solely by the wireless nodes. If the wireless nodes discover that the transmission resources scheduled by the first service node and the second service node conflict with each other, they may report the resource conflict information to the second centralized unit, and the second centralized unit may then decide how to avoid the conflict.

[0091] Specifically, the second centralized unit adjusts scheduling for the wireless node or allocates resources for the second service node based on the resource conflict information, and through the above method, the scheduling conflict probability for the wireless node can be reduced.

[0093] In this embodiment, the wireless node may supplementarily coordinate the scheduling resources of the wireless nodes between the first service node and the second service node. Specifically, when the wireless node finds that the transmission resources scheduled by the first service node and the second service node collide with each other, it may report resource collision information to the first service node, the second service node, the first centralization unit, or the second centralization unit, and the first service node, the second service node, the first centralization unit, or the second centralization unit may then decide how to avoid the conflict.

[0094] In one embodiment, the first centralized unit may control the first service node to adjust scheduling for the wireless node or redetermine resource allocation coordination information after receiving the resource conflict information, and the first service node can reduce the scheduling collision probability for the subsequent wireless node by adjusting scheduling for the wireless node after receiving the resource conflict information.

That is, the method of the embodiments of the present application can be applied to a method for coordinating resource allocation between two parent IAB-DUs when the two parent IAB-DUs belong to different CUs in the case of same-frequency DC or same-frequency-band different-frequency DC of an IAB network, and this method can also be applied to dual connectivity of an NR / LTE UE under the same conditions.

[0114] In some embodiments of the present application, the wireless node includes an IAB node or a UE, where the IAB node includes an MT and a DU. That is, the method of the embodiments of the present application can be applied to a method for coordinating resource allocation between two parent IAB-DUs when the two parent IAB-DUs belong to different CUs in the case of same-frequency DC or same-frequency-band different-frequency DC of an IAB network, and this method can also be applied to dual connectivity of an NR / LTE UE under the same conditions. According to the embodiments of the present application, resource allocation conflicts and scheduling conflicts between the MCG link and SCG link of a UE or MT can be reduced or avoided.

[0120] In this embodiment, the second centralization unit allocates resources for the second service node of the added wireless node based on the resource allocation coordination information, and then feeds back the resource allocation information of the second service node to the first centralization unit. The first centralization unit may further adjust the resource allocation information of the first service node based on the resource allocation information of the second service node, thereby better ensuring that the scheduling resources of the first service node for the wireless node and the scheduling resources of the second service node for the wireless node do not collide, and improving the success rate of scheduling for the wireless node.
