Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communications, and in particular to a method, an apparatus and a communication device for determining a target resource type. Background Art

[0002] In the New Radio (NR) system, Integrated Access Backhaul (IAB) can provide extended coverage for NR cells and capacity enhancement for NR cells. The access node that supports wireless access of user equipment (UE, also known as terminal equipment) and wirelessly backhauls data is called IAB node (IAB node, IABN). Data is transmitted between UE and access node through wireless access link (access link), and data can be transmitted between access nodes through wireless backhaul link (backhaul link).

[0003] In the IAB network architecture that supports the separate deployment of centralized units (CU) and distributed units (DU), an IAB node can include a DU function part and a mobile terminal (MT) function part. Relying on the MT function part, an access node (i.e., IABN) can find an upstream access node (i.e., Parent IABN, P-IABN) and establish a wireless backhaul link with the DU of the upstream access node. After an IAB node establishes a complete backhaul link, the IAB node turns on its DU function, and the DU will provide cell services, that is, the DU can provide network access services for the UE.

[0004] Among them, in the IAB system, the child IAB node (IAB node) receives control information from the parent IAB node (parent IABnode / parent node), and the control information can be used to indicate the resource type of the IAB DU cell. If the IABnode is controlled by multiple parent IAB nodes, for example, the IAB node is dual-linked with two parent nodes, connected to parent node 1 through the Master Cell Group (MCG), and connected to parent node 2 through the Secondary Cell Group (SCG). At this time, the IAB node will receive control information from different parent IABnodes, and the control information sent to the IAB node by different parent IAB nodes may not be the same, which will cause the IAB node to misunderstand the resource type of the IAB DU cell, affecting the transmission reliability and effectiveness. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a method, apparatus and communication device for determining a target resource type, which can avoid the sub-IAB node from misunderstanding the resource type, thereby ensuring transmission reliability and effectiveness.

[0008] According to a third aspect, a device for determining a target resource type is provided, comprising: a determination module for determining the target resource type according to resource type indication information received from at least one of the parent IAB nodes when connected to at least two parent IAB nodes.

By determining the target resource type according to resource type indication information received from at least one of the parent IAB nodes when connected to at least two parent IAB nodes, the target resource type can be avoided in a case where the child IAB node is connected to at least two parent IAB nodes and the resource type indication information sent by the at least two parent IAB nodes may be different, thereby avoiding a child IAB node from misunderstanding the resource type.

It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0032] The method for determining the target resource type provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0033] like Figure 2 As shown, an embodiment of the present invention provides a method 200 for determining a target resource type. The method can be executed by a sub-IAB node. In other words, the method can be executed by software or hardware installed in the sub-IAB node. The method includes the following steps:

[0034] S202: When connected to at least two parent IAB nodes, determine a target resource type according to resource type indication information received from at least one of the parent IAB nodes.

[0035] When a child IAB node is connected to at least two parent IAB nodes (e.g. Figure 1 In the case of Parent1 and Parent2 as shown in the figure, resource type indication information from Parent1 and resource type indication information from Parent2 may be received, and the resource type indication information is used to indicate the target resource type, for example, the resource type of the IAB DU cell. However, the resource type indication information sent by Parent1 and Parent2 may be different. In order to avoid the child IAB node from misunderstanding the resource type, in this step, the target resource type is determined according to the resource type indication information received from at least one of the parent IAB nodes.

[0036] like Figure 3 As shown, an embodiment of the present invention provides a method 300 for determining a target resource type. The method can be executed by a sub-IAB node. In other words, the method can be executed by software or hardware installed in the sub-IAB node. The method includes the following steps:

[0037] S302: When connected to at least two parent IAB nodes, process the resource type indication information received from at least one of the at least two parent IAB nodes according to a preset processing rule to determine the target resource type.

[0038] This step may include the following implementation methods.

[0039] In a first implementation, a target parent IAB node can be determined from the at least two parent IAB nodes; and the target resource type is determined according to the resource type indication information sent by the target parent IAB node. The child IAB node only receives or obeys the indication information of one parent node (e.g., MCG cell / SCG cell), and does not receive or obey the indication information of other parent nodes, thereby avoiding the child IAB node's misunderstanding of the resource type when multiple parent nodes send different indication information, so that the transmission performance is guaranteed.

[0040] Optionally, the target parent IAB node is preset, for example, agreed upon by a communication protocol, or configured by a network device, for example, only receiving / obeying the instruction information of the MCG.

[0041] In a second implementation manner, when the resource type indication information for the same resource indicates the same resource type, the resource type indication information takes effect.

[0042] The child IAB node considers the indication information of the multiple parent nodes at the same time. For a resource that needs to indicate the resource type, the indication information is valid only when the resource type indicated by all the indication information for the resource received from multiple parent nodes is the same, otherwise the indication information is invalid. Optionally, the multiple parent nodes are all or part of the parent nodes that can indicate the resource type of the resource. For example, when the downlink control information (DCI) format 2_5 indicates that the DU soft resource is hard / NA, the IAB node considers the DU soft resource to be hard / NA only when all parent nodes connected to the child IAB node (all parent nodes that can indicate the DU soft resource) indicate that the DU soft resource is hard.

[0043] In a third implementation, a logical operation is performed on the values ​​of all resource type indication information for the same resource, and based on the result of the logical operation, it is determined whether the same resource is the target resource type, wherein the logical operation includes at least one of the following: a logical AND operation, a logical OR operation, and an XOR operation. The resource type indication information is binary information. For example, for a soft type resource indication, the soft type can be indicated as 'available' or 'unavailable', 'available' can be regarded as '1', and 'unavailable' can be regarded as '0'. Therefore, if the result of the logical operation is 0, it can be determined that the same resource is not the target resource type, and if the result of the logical operation is 1, it can be determined that the same resource is the target resource type.

[0044] In a fourth implementation, when at least two resource type indication information are received and the effective time periods of the at least two resource type indication information overlap, a resource indicated by the indication information with overlapping effective time periods and having no indication conflict is determined as a first target resource, and conflicting resources are ignored, and a target resource type corresponding to the first target resource is determined according to the resource type indication information. Optionally, the indication conflict may include situations such as different resource types indicated by the indication information.

[0045] In a fifth implementation, when at least two resource type indication information are received and the effective time periods of the at least two resource type indication information overlap, the resource indicated by the indication information with overlapping effective time periods and having an indication conflict is determined as the second target resource, and the target resource type corresponding to the second target resource is determined according to the priority of the at least two resource type indication information. Optionally, the indication conflict may include situations such as different resource types indicated by the indication information.

[0046] Optionally, the determination of the priority of the resource type indication information includes at least one of the following:

[0047] The priority of the resource type indication information is determined according to the type of the cell receiving the resource type indication information; for example, the available resource indication from the PCell is prioritized; the available resource indication from the MCG is prioritized.

[0048] The priority of the resource type indication information is determined according to the resource type indication information. The MCG / SCG cell indicates the priority value in the PDCCH, and the IAB node compares the priorities by the priority value after receiving multiple available resource indications. When the priorities of multiple available resource indications are the same, the priorities can be determined according to a predetermined priority order. For example, the available resource indication from the PCell takes priority; the available resource indication from the MCG takes priority.

[0049] The priority of the resource type indication information is determined according to a preset rule. For example, the priority order of commands from the SCG Cell or MCG cell is specified by the protocol or configured by the CU. For example, the priority of the command is determined autonomously by the child IAB node.

[0050] In addition, the determining the priority of the resource type indication information according to the preset rules may also include: determining the priority of the resource type indication information according to at least one of the quality of the wireless channel, the amount of resources, and the amount of data that can be transmitted. Among them, according to the quality of the wireless channel, for conflicting resources, the IAB node gives priority to using resources with good wireless channel quality and abandons the use of conflicting resources with relatively poor wireless channel quality. According to the amount of resources, such as the bandwidth of the carrier or BWP. The corresponding available resource with a large bandwidth is given priority to use and the resource with a narrow bandwidth is abandoned. According to the amount of data that can be transmitted. You can try to determine the data transmission parameters for the conflicting resources, such as rank, MCS, number of PRBs, number of OFDMs, and position overhead to determine the amount of data that can be transmitted; determine the priority by comparing the amount of transmitted data.

[0051] The sixth type: when the resource type indication information received from one of the at least two parent IAB nodes conflicts with the scheduling information received from another of the at least two parent IAB nodes on a third target resource, the resource type of the third target resource is determined according to the resource type indication information or the scheduling information.

[0052] For example, for the resources of a certain IAB DU serving cell, the IAB node receives a command from the MCG cell indicating that the resources are available, but some of the resources indicated as available have multiplexing conflicts (e.g., resource overlap) with the resources scheduled to the IAB MT on the SCG link. Then, the MT performs the following actions: the IAB MT still uses the resources scheduled by the parent IAB node for transmission, but ignores that the resources are available resources for the DU; or, the IAB MT abandons the resources available for the DU.

[0053] Therefore, the embodiment of the present invention processes the resource type indication information received from at least one of the at least two parent IAB nodes according to a preset processing rule to determine the target resource type, thereby avoiding misunderstanding of the resource type by the child IAB node and ensuring transmission performance.

[0054] like Figure 4 As shown, an embodiment of the present invention provides a method 400 for determining a target resource type. The method can be executed by a sub-IAB node. In other words, the method can be executed by software or hardware installed in the sub-IAB node. The method includes the following steps:

[0055] S402: When connected to at least two parent IAB nodes, determine a target resource type according to a first configuration mode of the resource type and the resource type indication information.

[0056] Among them, in the first configuration mode of the resource type, the objects of configuration of the resource type are a first configuration object and a second configuration object, wherein the first configuration object is a mobile terminal cell MT cell or a terminal cell group MTcell group, and the second configuration object is a distributed unit cell DU cell corresponding to the terminal cell MT cell or the terminal cell group MT cell group. For example, the configuration of the IAB resource type is each {DU cell, MT cell} pair, so that the DU cell can determine its corresponding MT cell.

[0057] Among them, at least the resource type configuration information of the DU cell can be exchanged through the first target information transmitted between the centralized units CU. At least the serving cell configuration of the DU managed by the CU and / or the resource type configuration of the serving cell can be exchanged. Optionally, the information exchange needs to be performed at least when the same DU is connected to different CUs.

[0058] This step can ensure that different MT cells independently correspond to one DU cell, and the signaling received by the MT cell only acts on the corresponding DU cell. If the DU cell resources corresponding to different MT cells do not overlap or meet the configuration restrictions, the IAB node can avoid misunderstanding the IAB DU cell resource type.

[0059] like Figure 5 As shown, an embodiment of the present invention provides a method 500 for determining a target resource type. The method can be executed by a sub-IAB node. In other words, the method can be executed by software or hardware installed in the sub-IAB node. The method includes the following steps:

[0060] S502: When connected to at least two parent IAB nodes, determine a target resource type based on the resource type indication information and the acquired restriction condition.

[0061] This step may include the following implementations:

[0062] In a first implementation manner, resources of a DU serving cell of an IAB node are configured through high-layer signaling to be non-overlapping with resources of an IAB MT serving cell belonging to a different cell group or a DU serving cell of a different parent IAB node.

[0063] Specifically, through high-level configuration restrictions (such as restrictions on F1-AP / RRC signaling configuration), the resources of an IAB DU serving cell cannot overlap with the resources of an IAB MT serving cell belonging to a different cell group or a DU serving cell of a different Parent node. In other words, the resources of an IAB DU serving cell can only overlap with the resources of an IAB MT serving cell of a cell group / a DU serving cell of a Parent node at most.

[0064] Let's take an example to illustrate:

[0065] Figure 6aA schematic diagram of an example of an embodiment of the present invention is shown. As shown in the figure, the frequency band occupied by MT cell group 1 (CG 1), MT cell group 2 (CG 2), and the two frequency bands of CG 1 and CG 2 do not overlap. The frequency domain resources occupied by DU cell (CG 0) may not overlap with both CG 1 and CG 2 (scenario 1); or, the frequency domain resources occupied by CG 0 overlap with only one of CG 1 and CG2 (scenario 2). However, the frequency domain resources occupied by CG 0 cannot overlap with both CG 1 and CG 2 (scenario 3), that is, scenario 3 is not allowed in this step.

[0066] The overlap includes time domain and / or frequency domain resource overlap, and the overlap includes that the frequency domain resource isolation / interval is less than a certain value (or in other words, in the part where the time domain resources overlap, the frequency domain resource isolation / interval is less than a certain value).

[0067] In the second implementation, when the resources of an IAB node DU serving cell overlap with the resources of an IABMT serving cell belonging to a different cell group or a DU serving cell of a different parent IAB node, the resource type configuration configured by high-layer signaling satisfies the following resource type configuration conditions:

[0068] The resource type configuration condition includes: when the IAB node DU service cell is configured as a soft type at a target time, at the target time, at most one of the resource type configurations of the DU service cells of different parent IAB nodes is a target type, and the target type is at least one of the following: Hard type, Soft type, or NA type.

[0069] Let's take an example to illustrate:

[0070] Figure 6b A schematic diagram showing another example of an embodiment of the present invention is shown. When the IAB DU cell is configured as Soft, one of the parent node 1 and the parent node 2 can set its DU cell to Hard / soft, for example, parent node 2 can set its DU cell to Hard / soft, and the other can set it to NA, for example, parent node 1 can set its DU cell to NA.

[0071] Optionally, at least resource type configuration information of the DU cell may be exchanged through the second target information transmitted between the centralized units, wherein the information exchange is required at least when the same DU is connected to different CUs.

[0072] In addition, when the resource type configuration does not satisfy the resource type configuration restriction, an error may be reported to the centralized unit or at least one of the parent IAB nodes.

[0073] In a third implementation manner, at least one of the following preset indication restrictions is used to ensure that the target resource types corresponding to the resource type indication information do not conflict:

[0074] Preset indication restriction 1: The mobile terminal MT receives resource type indication information only from one parent IAB node. In other words, the IAB MT does not expect to receive resource type indications from different parent nodes.

[0075] Preset indication restriction 2: In the case where the mobile terminal MT receives resource type indication information from at least two parent IAB nodes, at least two resource type indication information correspond to different distributed unit cells. In other words, if the IAB MT receives resource type indications from different parent nodes, the IAB MT does not expect the resource type indications to act on the same DU cell.

[0076] Preset indication restriction 3: When receiving resource type indication information from at least two parent IAB nodes through the mobile terminal MT, the effective time of the resource type indication information does not overlap. In other words, if the IAB MT receives resource type indications from different parent nodes, the IAB MT does not expect the effective time of the indications to overlap.

[0077] Preset indication restriction 4: When receiving resource type indication information from at least two parent IAB nodes through the mobile terminal MT, and the resource type indication information corresponds to the same distributed unit cell, the effective time of the resource type indication information does not overlap. In other words, if the IAB MT receives resource type indications from different parent nodes, when the resource type indications act on the same DU cell, the IAB MT does not expect the effective time of the indications to overlap.

[0078] Preset indication restriction 6: When receiving resource type indication information from at least two parent IAB nodes through the mobile terminal MT and the effective time of at least two resource type indication information overlaps, at least two resource type indication information do not conflict. In other words, if the IAB MT receives resource type indications from different parent nodes, if the effective time of the indications overlaps, the IAB MT does not expect the indication contents to be different.

[0079] Preset indication restriction 7: When receiving resource type indication information from at least two parent IAB nodes through the mobile terminal MT, the resource type indication information corresponds to the same distributed unit cell, and the effective time of at least two resource type indication information overlaps, at least two resource type indication information do not conflict. In other words, if the IABMT receives resource type indications from different parent nodes, if the resource type indications act on the same DU cell, and if the effective time of the indications overlaps, the IAB MT does not expect the indication contents to be different.

[0080] In this step, for example, restrictions may be placed on MAC CE or DCI indications.

[0081] Optionally, when the resource type configuration does not satisfy the resource type configuration restriction, or the resource configuration does not satisfy the resource configuration restriction, or the resource type indication does not satisfy the indication restriction, an error is reported to the centralized unit or at least one of the parent IAB nodes or the CU unit.

[0082] Combination of the above Figure 1-5 The method for determining the target resource type according to an embodiment of the present invention is described in detail. Figure 7 A method for determining a target resource type according to another embodiment of the present invention is described in detail. It can be understood that the interaction between the network device and the terminal device described from the network device side is similar to Figure 1-5 The description on the terminal device side in the method shown is the same, and to avoid repetition, the relevant description is appropriately omitted.

[0083] Figure 7 700 is a flowchart of a method for determining a target resource type according to an embodiment of the present invention. The method may be executed by a parent IAB node or a centralized unit CU. In other words, the method may be executed by software or hardware installed in the method executed by the parent IAB node or the centralized unit CU. The method includes the following steps:

[0084] S702: Send resource type indication information to a child IAB node connected to at least two parent IAB nodes.

[0085] The resource type indication information is used to determine the resource type indication information of the target resource type.

[0086] The resource type indication information is used to determine the resource type indication information of the target resource type, including at least one of the following implementation methods.

[0087] Implementation method 1: The first configuration method of the resource type in the resource type indication information is used to determine the target resource type; wherein, in the first configuration method of the resource type, the configuration object of the resource type is a first configuration object and a second configuration object, wherein the first configuration object is a mobile terminal cell MT cell or a terminal cell group MT cellgroup, and the second configuration object is a distributed unit cell DU cell corresponding to the terminal cell MT cell or the terminal cell group MT cell group.

[0088] Optionally, the resource type configuration information of the DU cell can be at least exchanged through the first target information transmitted between the centralized units CU. Figure 4 The relevant descriptions of the embodiments are similar and will not be repeated here.

[0089] Implementation method 2: Based on the resource type indication information and the acquired restriction condition, determine the target resource type so that the resource type indication information from different parent IAB nodes does not conflict.

[0090] In one implementation, when resources of a DU serving cell of an IAB node overlap with resources of DU serving cells of different parent IAB nodes, the resource type configuration configured through high-layer signaling satisfies the following resource type configuration conditions:

[0091] The resource type configuration condition includes: when the IAB node DU service cell is configured as a soft type at a target time, at the target time, at most one of the resource type configurations of the DU service cells of different parent IAB nodes is a target type, and the target type is at least one of the following: Hard type, Soft type, or NA type.

[0092] In one implementation, at least resource type configuration information of the DU cell may be exchanged through the second target information transmitted between the centralized units.

[0093] In one implementation, the target resource type can be determined based on the resource type indication information and the obtained restriction condition so that the resource type indication information from different parent IAB nodes does not conflict. The first information is received so that the resource type indication information from different parent IAB nodes does not conflict, including: making the target resource type corresponding to the resource type indication information not conflict through at least one of the following preset indication restrictions:

[0094] Receiving resource type indication information from only one parent IAB node through the mobile terminal MT;

[0095] In the case where the resource type indication information is received from at least two parent IAB nodes by the mobile terminal MT, at least two of the resource type indication information correspond to different distribution unit cells;

[0096] In the case where the resource type indication information is received from at least two of the parent IAB nodes through the mobile terminal MT, the effective time of the resource type indication information does not overlap;

[0097] In the case where the resource type indication information is received from at least two parent IAB nodes through the mobile terminal MT, and the resource type indication information corresponds to the same distribution unit cell, the effective time of the resource type indication information does not overlap;

[0098] In the case where resource type indication information is received from at least two parent IAB nodes through the mobile terminal MT and the validity time of at least two resource type indication information overlaps, at least two resource type indication information do not conflict;

[0099] When the resource type indication information is received from at least two parent IAB nodes by the mobile terminal MT, the resource type indication information corresponds to the same distribution unit cell, and the validity time of at least two resource type indication information overlaps, the at least two resource type indication information do not conflict.
