Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of communication technology, and in particular to a method and device for handling resource configuration conflicts. Background Art
[0002] As shown in Figure 1, when a cell-specific signal / channel is configured on an unavailable resource (or a soft resource that is not indicated as available), the resource is considered a hard resource. If the Integrated Access and Backhaul (IAB) node prioritizes the use of this resource to the Distributed Unit (DU), it will send a signal to the child Mobile Terminal (MT) via a downlink.

[0060] To facilitate understanding of the embodiments of the present application, the following technical points are first introduced below:
[0061] 1. Basic Concepts of IAB
[0062] In high-capacity scenarios using the fifth generation (5G) mobile communication technology, such as shopping malls, squares, and airports, the downlink data transmission rate can reach 300Mbps, the uplink data transmission rate can reach 50Mbps, and the downlink capacity can reach 750Gbps / km. 2 , uplink capacity can reach 125Gbps / km 2 To support such high transmission rates and capacity, large bandwidth and dense deployment are required, which high-frequency millimeter waves can meet. However, high-frequency millimeter waves are easily obstructed and have very limited coverage, so a denser deployment is required. To reduce dependence on and cost of optical fiber, IAB technology is needed. This adds backhaul capabilities to the access capabilities provided by base stations.
[0063] In the IAB scenario, the following definitions apply:
[0064] (1) IAB donor / node: An anchor point with optical fiber connection to the core network, such as Figure 1 DgNB in
[0065] (2) IAB node: a node that has no fiber connection and core network, but can be backhauled via wireless links and can provide access functions, such as Figure 1 In standardization research, the part of the IAB node that provides access functions is called DU, and the part that provides backhaul functions is called MT.
[0066] (3) Parent node: the previous hop node of a certain IAB node, such as Figure 1 The DgNB in is the parent node of IAB1;
[0067] (4) Child node: the next hop node of a certain IAB node, such as Figure 1 IAB2 in the above example is the child node of IAB1.
[0068] (5) Access link: The link between the terminal and the IAB node or IAB host node, including the uplink access link and the downlink access link, such as Figure 1 Links 1a, 2a, and 3 in the .
[0069] (6) Backhaul link: The link between the IAB node and the IAB child node or IAB parent node, including the uplink backhaul link and the downlink backhaul link, such as Figure 1 1b and 2b links in.
[0070] (7) Time Division Multiplexing (TDM): The MT side and DU side of an IAB node cannot transmit and receive at the same time. Specifically, Figure 1 The transmission resources for 1b and 2b need to be staggered in time. Similarly, the same applies to 1b and 2a, and 1b and 2a (or 2b). Currently, when discussing IAB resource allocation in the standardization phase, TDM multiplexing is considered.
[0071] II. IAB Resource Allocation
[0072] In current standardization research, the following time domain resource types are defined for the MT and DU of the IAB node:
[0073] (1) MT: Its mother link time domain resources include downlink (DL), uplink (UL), and flexible resources. The resource types and definitions can refer to existing protocols.
[0074] (2) DU: Its sublink time domain resources include downlink (DL), uplink (UL), flexible (Flexible) and NA resources. Among them, for DL, UL and Flexible resources, two additional resource types, Hard and Soft, are defined:
[0075] -Hard resources: Sublinks always have access to these resources and have a high priority in scheduling;
[0076] -Soft resources: Whether the sub-link is available is explicitly or implicitly controlled by the parent node; soft resources are unavailable by default. If the parent node does not schedule the resource, it can be indicated as available.
[0077] The following conclusions have been reached regarding Hard / Soft / NA resources on the DU side:
[0078] For Hard resources or Soft resources indicated as available: when the corresponding MT time domain resources need to send and receive cell-specific signals / channels (for example, synchronization / physical broadcast channel blocks, system message reception, random access channel), no additional special rules are defined.
[0079] - The IAB node decides based on its own implementation to give priority to the use of the resource to the DU or MT.
[0080] For NA resources or unavailable Soft resources (Soft not indicated as available): when cell-specific signals / channels are configured on the above resources, the above resources are considered as Hard DU resources (is treated as if it were a Hard DU resource).
[0081] 3. IAB Time Misalignment Issue
[0082] IAB supports multi-hop node scenarios, which will involve the time synchronization of network nodes. The current conclusion requires that the downlink transmission time of all base stations in the entire network be aligned, that is, the downlink transmission time of all IAB DUs is aligned. Figure 2 As shown in the figure, the downlink transmission time of IAB parent node DU (parent DU) and IAB node DU (IAB DU, I-DU) are aligned with the dotted line in the figure. Under the above time synchronization scheme, due to the propagation delay T between actual nodes, p , which results in a timing misalignment between the frame timing on the MT side of the IAB node and the frame timing on the DU side, and thus a configuration conflict occurs during subsequent resource allocation and resource type indication.
[0083] IV. IAB Resource Allocation Plan
[0084] To address the aforementioned time misalignment issue, a resource configuration solution has been proposed in current standardization research: the resource types on the DU and MT sides are displayed as unavailable (NA), and the Hard / Soft resources on the DU side are implicitly determined based on the configuration of the corresponding MT resources. Figure 3 As shown in the figure, for the DU, gray resources are displayed as NA resources; for the MT, gray resources are displayed as NA resources. Based on the displayed NA resources, the DU determines its own hard / soft resources based on the corresponding MT resources (i.e., according to the MT timing). Specifically, if the corresponding MT resource is NA, the DU determines it as a hard resource; otherwise, the DU determines it as a soft resource.

[0090] See also Figure 4 , an embodiment of the present application provides a method for handling resource configuration conflicts, which is applied to a first IAB node, and the specific steps include: step 401 and step 402.
[0091] Step 401: Acquire first information, where the first information is related to resource usage of a second IAB node, where the second IAB node is a child node of the first IAB node.
[0092] Step 402: Allocate resource usage priorities to the DU of the first IAB node or the MT of the first IAB node according to the first information.
[0093] In some implementations, in step 401, the first information is received from the second IAB node, where the first information includes: whether the NA resource of the MT of the second IAB node can be rewritten or whether the NA resource of the MT of the second IAB node cannot be rewritten;
[0094] In step 402, if the NA resource of the MT of the second IAB node cannot be rewritten, the resource usage priority is assigned to the MT of the first IAB node; if the NA resource of the MT of the second IAB node can be rewritten, the resource usage priority is assigned to the DU of the first IAB node.
[0095] In some implementations, in step 401, resource configuration information reported by the second IAB node is received; and / or the resource configuration information of the second IAB node is obtained by parsing signaling sent to the second IAB node.
[0096] Optionally, the signaling is signaling sent to the DU and / or MT of the second IAB node for semi-static resource configuration.
[0097] Optionally, the resource configuration information includes one or more of the following:
[0098] (1) DU resource configuration type;
[0099] (2) MT resource configuration type;
[0100] (3) Configuration information of the cell signal or channel on the DU;
[0101] (4) Configuration information of the cell signal or channel on the MT.
[0102] In some embodiments, the method further comprises:
[0103] If the resource usage priority is assigned to the DU of the first IAB node, a transmission or reception process is performed on the resource.
[0104] In some embodiments, the method further comprises:
[0105] A resource type change signaling is sent to the second IAB node, where the resource type change signaling is used to rewrite the type of the NA resource of the MT of the second IAB node.
[0106] In some embodiments, the method further comprises:
[0107] If the priority of resource usage is assigned to the MT of the first IAB node, no sending or receiving processing is performed on the resource.
[0108] In the embodiment of the present application, by allowing the parent node to obtain relevant useful information, ineffective scheduling of NA resources on the child node MT side can be avoided.
[0109] See also Figure 5 In an embodiment of the present application, a method for handling resource configuration conflicts is provided, which is applied to a second IAB node and includes: step 501.
[0110] Step 501: Send first information to a first IAB node, where the first information is related to resource usage of the second IAB node, and the first information is used by the first IAB node to assign resource usage priority to the DU of the first IAB node or the MT of the first IAB node, wherein the second IAB node is a child node of the first IAB node.
[0111] In some implementations, the first information includes: the NA resource of the MT of the second IAB node can be rewritten or the NA resource of the MT of the second IAB node cannot be rewritten.
[0112] In some implementations, the first information includes resource configuration information of the second IAB node.
[0113] Optionally, the resource configuration information includes one or more of the following:
[0114] (1) DU resource configuration type;
[0115] (2) MT resource configuration type;
[0116] (3) Configuration information of the cell signal or channel on the DU;
[0117] (4) Configuration information of the cell signal or channel on the MT.
[0118] In some embodiments, the method further comprises:
[0119] If the first information indicates that the NA resource of the MT of the second IAB node cannot be rewritten, no receiving or sending processing is performed according to the original NA resource configuration type;
[0120] If the first information indicates that the NA resource of the MT of the second IAB node can be rewritten, a receiving or sending process is performed on the NA resource.
[0121] In some embodiments, the method further comprises:
[0122] If the resource type change signaling sent by the first IAB node is received, a receiving or sending process is performed on the resource corresponding to the resource type change signaling.
[0123] In the embodiment of the present application, the parent node is informed of relevant useful information to avoid invalid scheduling of NA resources on the MT side.
[0124] In an embodiment of the present application, the parent node obtains useful information.
[0125] (1) Useful information may be the resource usage decision result of the child node.
[0126] The child node decides whether to prioritize resource usage on the DU side or the MT side, and reports the decision to the parent node.
[0127] Optionally, the reported information is whether the NA resource on the MT side can be rewritten;
[0128] If the NA resources on the MT side can be rewritten, the mother node DU understands that the child node has given priority to the use of conflicting resources to its MT side. The mother node DU will send cell-specific signals / channels, and the corresponding child node MT side will receive / measure;
[0129] If the NA resources on the MT side cannot be rewritten, the mother node DU understands that the child node has given the priority of using the conflicting resources to its DU side, and the mother node DU will not send cell-specific signals / channels. At this time, the MT resources corresponding to the DU side resources can be sent and received normally.
[0130] In an embodiment of the present application, the method for determining the resource usage priority of a sub-node is as follows:
[0131] (1) Based on the IAB node's own implementation;
[0132] (2) Alternatively, by defining additional attributes for the cell-specific signals / channels configured to be transmitted and received on these resources, the priority of resource use can be determined based on the attributes. For example, Figure 6 As shown in the configuration example, the second time slot of the C-DU is configured with a synchronization / broadcast channel block for general terminal access and is assigned a high priority attribute. Correspondingly, the second time slot of the I-DU (which will schedule the second time slot of the C-MT) is configured with a synchronization / broadcast channel block for IAB node mutual discovery and is assigned a low priority attribute. The IAB node can make a judgment based on the priority of the two cell-specific signals / channels.
[0133] (3) Alternatively, the judgment is made by configuring certain parameters of the cell-specific signals / channels transmitted and received on these resources. For example, Figure 6As shown in the configuration example, the second time slot of the C-DU and the second time slot of the I-DU are both configured with synchronization / broadcast channel blocks for IAB nodes to discover each other (with no difference in priority attributes). The IAB node can make judgments based on the periods of the two synchronization / broadcast channel blocks. For example, priority can be given to cell-specific signals / channels with longer periods.
[0134] (2) Alternatively, the useful information may be the sub-node DU resource configuration information.
[0135] The parent node determines whether to prioritize resource usage on the DU side or the MT side based on the child node DU resource configuration information;
[0136] If the mother node gives priority to the DU side, it will send a signal to rewrite the NA resource on the child node MT side. At this time, the mother node will transmit and receive on the DU resource, and the corresponding child node resource type will be rewritten, and it will also receive / measure.
[0137] Otherwise, the mother node gives the resource usage priority to the MT side, and the DU does not use the resource;
[0138] It should be noted that the method for the parent node to determine resource usage is the same as that described for the child node.
[0139] In the embodiment of the present application, the parent node obtains useful information in the following manner:
[0140] (1) Child node reporting: The child node reports the resource usage priority decision result and / or its DU-side resource configuration information to the parent node using signaling, such as physical layer signaling, MAC layer signaling, and RRC signaling;
[0141] (2) The mother node parses the signaling sent to the child node: When using F1-AP and RRC signaling to perform semi-static resource configuration for the child node's DU and MT respectively, the mother node is allowed to parse the configuration content of the child node, so that the mother node can know the resource configuration information of the child node.
[0142] In an embodiment of the present application, resource conflicts and resource waste caused by the introduction of NA resources on the MT side are avoided by having the child node report the resource usage priority judgment result, the child node report the resource configuration content, or allowing the parent node to parse the child node configuration content.
[0143] For the mother node DU: if the child node reports that the resources on the child node MT side cannot be rewritten, the mother node DU will not send / receive on the corresponding resources; if the child node reports that the resources on the child node MT side can be rewritten, the mother node can send / receive on the corresponding resources.
[0144] For the mother node DU: Based on the resource configuration information reported by the child node and / or based on the parsed child node resource configuration information, if it is decided to give priority to resource usage to the DU, the mother node rewrites the type of MT resources corresponding to the child node, and the mother node can send / receive; if it is decided to give priority to resource usage to the MT, the mother node DU does not send / receive.
[0145] For the child node MT: If the child node reports that the MT side resources cannot be rewritten, the receiving / sending behavior will not be performed according to the original NA resource configuration type; if the child node reports that the MT side resources can be rewritten, the MT side can receive / send on the corresponding resources.
[0146] For the child node MT: if the resource type rewriting signaling sent by the parent node is received, the child node MT can perform receiving / sending behavior on the corresponding resource.
[0147] Furthermore, the child node reports the resource usage priority decision result to the parent node, and the information content indicates whether the NA resource of the associated MT can be rewritten.
[0148] The child node reports the resource configuration information of its DU and / or MT to the parent node. The information content includes but is not limited to: DU resource configuration type (D / U / F / H / S / NA), MT resource configuration type (D / U / F / NA), cell-specific signals / channels configured on DU and / or MT and their configuration information, such as priority attributes, period, offset, index and other configuration parameters.
[0149] The mother node sends signaling to the child node, and the information content can rewrite the NA resource type of the associated MT; the signaling of the mother node to the child node's DU and / or MT for semi-static resource configuration can be parsed by the mother node.
