Description

Technical Field

[0001] The present application relates to, but is not limited to, the field of communications, and specifically, to an information transmission method and device. Background Art

[0002] In related technologies, a potential technology for future network deployment is to support wireless backhaul to achieve flexible and dense deployment of new radio cells (NR) without deploying the transmission network in proportion.

[0003] The Integrated Access Backhaul (IAB) node includes a mobile terminal (MT) and a distributed unit (DU). The MT functions as a UE within the IAB node, so its resource configuration follows that of Rel-15. The following states are introduced for the DU. Table 1 shows the DU state table based on related art:

[0004] Table 1

[0005] Hard DL Soft DL Hard F Soft F Hard UL Soft UL NA

[0006] For DU resources, which are configured from the network's centralized unit (CU), the soft resources in the CU-configured DU resources can be further indicated as available or unavailable by the relay node's parent node. The relay node's mobile terminal (MT) and distributed unit (DU) functional units are limited to half-duplex.

[0007] Therefore, the following issues need to be addressed: For a time domain resource, if a MT is configured for uplink or downlink transmission and a DU on the same IAB node is configured as hard, or if a DU on the same IAB node is configured as soft and further indicated as available, both the MT and the DU must perform the corresponding transmission. However, the IAB node itself is limited to half-duplex mode, so a conflict resolution solution must be considered.

[0008] There is currently no effective solution to the problem in related technologies of how a communication node coordinates multiple configurations to complete information transmission when receiving multiple configurations. Summary of the Invention

[0009] The embodiments of the present application provide an information transmission method and apparatus to at least solve the problem in the related art of how a communication node coordinates multiple configurations to complete information transmission when receiving multiple configurations.

[0012] According to another embodiment of the present application, a storage medium is provided, in which a computer program is stored. The computer program is configured to execute the steps of any one of the above method embodiments when running.

[0013] According to another embodiment of the present application, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor is configured to run the computer program to perform the steps in any one of the above method embodiments.

Optionally, the SSB with a larger period has a higher priority.

[0072] Optionally, the node 1 processes the transmission configuration information according to a preset rule and performs communication, including:

[0089] The following is an explanation in conjunction with another embodiment of the present application.

[0090] Figure 2 FIG. 1 is a schematic diagram of the relationship and links between nodes in an IAB network according to another embodiment of the present application. Figure 2 As shown in the figure, the three nodes from top to bottom are respectively called the source node Root node, the first hop node First hop node, and the second hop node Second hop node. The Root node can be called the parent node of the First hop node, and the Second hop node can be called the child node of the First hop node.

[0091] In this topology, the root node is physically a gNB. The gNB acts as a root node with only a distributed unit (DU). The relay node, called an integrated access and backhaul node (IAB), has both a second unit (secondary unit) and a first unit (first unit) that functions as a terminal. The link between the first hop node and its root node is called a backhaul link, which is further divided into a downlink (backhaul DL) and an uplink (backhaul UL). The link between the first hop node and its second hop node is called an access link, which is further divided into a downlink (access DL) and an uplink (access UL).

[0092] The communication node served by the second unit DU described in this application is the next-hop child node terminal, and can also be further specified as a specific functional unit of the next-hop child node.

[0093] The determination of link type is based on the relative relationship and roles of nodes, e.g. Figure 2 If the child node Second hopnode is a common terminal, then this link is a common access link for it. If the child node Second hopnode is an IAB node, then from the perspective of this IAB node, this link is a backhaul link.

[0094] In Rel-14, backhaul and access links of relay nodes are time-division multiplexed. However, for NR IAB networks, due to the introduction of multi-hop relays, 3GPP's resource allocation must be considered from the perspective of the two functional units of the IAB node, the DU and the MT. WI supports time-division resource multiplexing of the DU and MT, while also considering forward compatibility with frequency division multiplexing (FDM) and space division multiplexing (SDM).

[0095] Due to the limitation of half-duplex operation of IAB nodes, it is necessary to consider how to prevent time conflicts between MT operation and DU operation of IAB.

[0096] This document uses the terms "DU" and "MT" to describe the relationship between DUs and MTs within the same node. When describing MTs and DUs between different nodes, the prefixes "child" or "parent" are added. For example, "child MT" and "DU" represent the DU of an IAB and the MT of its child IAB node.

[0097] The resource types identified for DU resources include hard and soft. Hard resources are available to the DU and are used for child link scheduling. The availability of soft resources for the DU requires further confirmation, for example, through explicit or implicit means. This application describes efficient multiplexing of signaling channels during IAB multiplexing between DUs and mobile devices, taking into account hard or soft resource types.

[0098] The relationship between the two indications of soft resources.

[0099] First, for the final IAB operation of a given MT frame structure configuration, DU configuration, and specific MT channel configuration, this application provides two methods: 1) For MT type 1 signals and channels, MT operations take precedence over DU (hard attribute) resource configuration; 2) The configuration of the child DU is visible to the parent node, and the parent node must avoid the type group 1 resources of the child DU when configuring the MT type 1 signals and channels.

[0100] Here, the type 1 signal and channel include at least one of the following:

[0101] the channel or signal used for measurement;

[0102] the channel or signal used for access;

[0103] A channel or signal used to deliver system messages.

[0104] Type Group 1 includes at least one of the following:

[0105] Hard type downlink DL (Downlink);

[0106] Hard type uplink UL (Uplink);

[0107] Hard type is flexible;

[0108] * Regarding 2) above, another description of the protocol is that the type 1 signal and channel correspond to the resources of type group 2 of the child DU, where type group 2 includes at least one of the following:

[0109] Soft type of DL;

[0110] Soft type UL;

[0111] Soft type Flexible;

[0112] NA.

[0113] Secondly, as can be seen from the table above, DU resource types are broadly categorized as D, F, U, and NA. The attributes of D, F, and U are further subdivided into Hard and Soft. Hard DL resources are directly usable by the DU functional node for at least downlink scheduling of its child nodes' access links. However, the availability of soft resources requires explicit or implicit notification from the parent node to the child DU. Once soft resources are explicitly or implicitly indicated as available by the parent node, they can be used for Type 2 signal and channel transmission.

[0114] Type 2 signals and channels include at least one of the following:

[0115] SRS transmission of child nodes;

[0116] Physical downlink shared channel PDSCH reception of the child node;

[0117] Physical uplink control channel PUCCH transmission of the child node;

[0118] Channel state information (CSI) measurement of child nodes;

[0119] The physical uplink shared channel PUSCH of the child node is sent.

[0120] Again, there are explicit and implicit ways to indicate soft resources. Consider the following two ways:

[0121] The explicit mode and the implicit mode work independently, that is, IAB always works under only one of the indication modes at a certain time;

[0122] The explicit and implicit modes work in a hybrid manner, and the combination of the explicitly indicated state and the implicitly indicated state determines the final resource state. The embodiments herein include:

[0123] ① The available attribute of explicit indication is better than the result of implicit indication;

[0124] ② The explicitly indicated available can be overwritten by the implicitly indicated result;

[0125] ③ The explicitly indicated not available attribute can be further implicitly indicated as available.

[0126] The invention points of this application are: ① specific IAB behavior for given DU and MT resource configuration; ② limiting given signals and channels to specific resources (avoiding hard type resources); ③ determining the availability of soft resources.

[0127] The following is further explained with examples.

[0128] Example 1: From the IAB behavior description: MT configures SSB, the RACH channel overlaps with the DU hard resources, and the MT operation is executed first.

[0129] Figure 3 is a schematic diagram according to Example 1 of this application, such as Figure 3 As shown, in this example, a synchronization signal / PBCH block (SSB) is configured on the downlink resources of the first unit MT of the integrated access and backhaul link node IAB (Integrated Access Backhaul), and the position where the time domain overlaps with the synchronization signal / PBCH block resource corresponds to the hard resource of the distributed unit DU of the integrated access and backhaul link node IAB.

[0130] The hard resources that overlap with the SSB time domain can be transmitted in either uplink, downlink, or flexible directions. When a conflict occurs between the hard time domain resources of the first MT and the distributed unit DU of the same integrated access and backhaul node IAB, the SSB reception measurement operation for the first MT of the IAB takes precedence.

[0131] Figure 3 Similarly, a random access channel (RACH) is configured on the uplink resources of the first MT unit of the integrated access and backhaul node IAB. The location where the time domain overlaps with the synchronization broadcast block (SSB) resources corresponds to the hard resources of the distributed unit (DU) of the integrated access and backhaul node IAB. The hard resources at the location where the time domain overlaps with the random access channel (RACH) can be transmitted in the uplink, downlink, or flexible direction. When a conflict occurs between the random access channel (RACH) and the hard time domain resources of the distributed unit (DU) of the first MT unit of the same integrated access and backhaul node IAB, the RACH transmission operation of the first MT unit of the integrated access and backhaul node IAB is prioritized.

[0132] In summary, when the first MT of the integrated access and backhaul node IAB is configured with Type 1 signals and channels, the integrated access and backhaul node IAB does not expect hard resources to appear in its distributed unit (DU) in the area where they overlap with the Type 1 signals and channels of the first MT. When hard resources appear on the distributed unit (DU) in the time domain corresponding to the Type 1 signals and channels of the first MT, the integrated access and backhaul node IAB determines that the distributed unit (DU) resource configuration is incorrect and performs transmission and reception operations for the Type 1 signals and channels corresponding to the first MT.

[0133] Furthermore, the type 1 signal channel of the first unit MT of the integrated access and backhaul link node IAB may also be a pilot for measurement.

[0134] The pilot signal used for wireless channel measurement includes at least one of the following:

[0135] Channel-State Information Reference Signal (CSI-RS);

[0136] Demodulation Reference Signal (DMRS) can be a demodulation reference signal for service data or a demodulation reference signal for control data.

[0137] Phase Tracking Reference Signal PTRS (Phase Tracking Reference Signal).

[0138] Furthermore, the type 1 signal channel of the first unit MT of the integrated access and backhaul link node IAB may also be used for transmitting system information SI.

[0139] like Figure 3 The first unit (MT) and the distributed unit (DU) are two functional units of the same integrated access and backhaul link node (IAB). Some time domain resources used for measuring and synchronizing the local cell's synchronization broadcast block (SSB) overlap with the hard attribute resources of the distributed unit (DU). Other time domain resources used for random access to the local service cell's random access channel (RACH) overlap with the hard attribute resources of the distributed unit (DU). The signal and channel configuration used by the first unit (MT) to transmit the synchronization broadcast block and the random access channel (RACH) belong to type 1 of the first unit's transmission configuration.

[0140] The pilot signal used for downlink synchronization and measurement of the serving cell and the pilot signal used for uplink synchronization of the serving cell also belong to the type 1 signal and channel configuration of the first unit MT.

[0141] Figure 3 Only one type of overlapping situation of the signal and channel of the transmission configuration of the first unit MT and the hard resources of the distributed unit DU is given, and no restriction is imposed on other overlapping combinations of the signal and channel of the transmission configuration of the first unit MT and the hard resources of the distributed unit DU. Other overlapping combinations are also within the scope of protection of the present invention.

[0142] Example 2: Behavior description from IAB: The MT is configured with SSB and is instructed by IAB to perform at least one SSB measurement within a specified period.

[0143] The integrated access and backhaul link node IAB is configured with a period T for measuring SSB, and the mobile terminal unit is required to perform SSB measurement at least once within the period T.

[0144] The mobile terminal unit MT performs at least one SSB reception measurement within a period T. The criterion for selecting resources for measuring the SSB is: giving priority to SSB resources that do not overlap with DU hard resources.

[0145] When the hard resource of the distributed unit DU partially conflicts with the synchronized broadcast block SSB of the mobile terminal unit MT of the local node, the MT selects at least one synchronized broadcast block SSB that does not overlap with the hard resource of the distributed unit DU for reception measurement according to the period T indicated by the high-layer signaling;

[0146] When the hard resource of the distributed unit DU completely conflicts with the synchronous broadcast block SSB of the mobile terminal unit MT of the local node, at least one SSB overlapping with the hard resource of the distributed unit DU is selected for reception measurement.

[0147] Example 3: From the IAB behavior description: MT configures SSB, the RACH channel overlaps with the DU hard resources, and the MT operation is executed first.

[0148] Figure 4 is a schematic diagram according to Example 3 of this application, such as Figure 4 As shown, in this example, a synchronization signal / PBCH block (SSB) is configured on the downlink resources of the mobile terminal unit MT of the integrated access and backhaul link node IAB (Integrated Access Backhaul), and the position where the time domain overlaps with the synchronization signal / PBCH block resource corresponds to the hard resource of the distributed unit DU of the integrated access and backhaul link node IAB.

[0149] When the synchronous broadcast block SSB of the mobile terminal unit MT of the same integrated access and backhaul link node IAB conflicts with the hard time domain resources of the distributed unit DU and the conflict position corresponds to the SSB transmission operation of the distributed unit DU, the SSB transmission operation of the distributed unit DU is executed first.

[0150] Figure 4Similarly, a random access channel RACH is configured on the uplink resources of the mobile terminal unit MT of the integrated access and backhaul link node IAB. The position where the time domain overlaps with the random access channel RACH resource corresponds to the hard resources of the distributed unit DU of the integrated access and backhaul link node IAB, and the hard resources in the overlapping area are used to send system information SI. Then the distributed unit DU of the integrated access and backhaul link node IAB performs the corresponding operation.

[0151] In summary, when hard resources are present in the distributed unit (DU) of the integrated access and backhaul node (IAB) and are used for SSB or SI transmission, and when hard resources corresponding to the type 1 signal and channel of the mobile terminal unit (MT) are present on the distributed unit (DU), the integrated access and backhaul node (IAB) prioritizes SSB or SI transmission of the distributed unit (DU).

[0152] Example 4: From the IAB behavior description: MT configures SSB and DU hard resources to overlap and determines the priority based on the cycle relationship.

[0153] Figure 5 This is an example according to Example 4 of this application Figure 1 ,like Figure 5 As shown, in this example, a synchronization signal / PBCH block (SSB) is configured on the downlink resources of the mobile terminal unit MT of the integrated access and backhaul link node IAB (Integrated Access Backhaul), and the position where the time domain overlaps with the synchronization signal / PBCH block resource corresponds to the hard resource of the distributed unit DU of the integrated access and backhaul link node IAB.

[0154] When a conflict occurs between the synchronized broadcast block (SSB) of a mobile terminal unit (MT) and the hard time domain resources of a distributed unit (DU) on the same integrated access and backhaul link node (IAB), and the location of the conflict corresponds to the SSB transmission operation of the distributed unit (DU), the priority is determined based on the period of the synchronized broadcast block (SSB) corresponding to the distributed unit (DU) and the period size of the synchronized broadcast block (SSB) corresponding to the mobile terminal unit (MT). The configuration of the SSB to be received on the mobile terminal unit (MT) is also called the SSB-based measurement timing configuration (SMTC), and the SSB to be transmitted by the distributed unit (DU) is also called the SSB transmission configuration (STC).

[0155] Figure 5In [1], the period of SMTC is 40ms and the period of STC is 20ms.

[0156] When the period of SMTC is greater than that of STC, the measurement and discovery operations of the SMTC position have a higher priority.

[0157] In one approach, when some resources of the SMTC and the STC overlap, measurement and discovery operations are performed on the SMTC location.

[0158] In one approach, when the resources of the SMTC and the STC completely overlap, measurement and discovery operations are performed at the SMTC location.

[0159] In one way, when some resources of SMTC and STC overlap, the measurement and discovery operations on the SMTC position are performed in the overlapping area, and the STC with low priority in non-overlapping resources also performs the sending operation, corresponding to Figure 5 The distributed unit DU of the SSB integrated access and backhaul link node IAB outside the dotted rectangular box performs SSB transmission.

[0160] Figure 6 This is an example according to Example 4 of this application Figure 2 ,like Figure 6 Figure 2 shows another SMTC and STC configuration scenario. The STC period configured for the DU is 40ms, while the SMTC period configured for the MT on the same node is 20ms. In this configuration, if the STC period is greater than the SMTC period, the STC takes precedence. If a resource conflict occurs on a relay node, the STC operation corresponding to the relay node's DU takes precedence.

[0161] In one method, when some resources of SMTC and STC overlap, an SSB sending operation is performed at the STC position.

[0162] In one method, when the resources of SMTC and STC completely overlap, the SSB sending operation is performed at the STC position.

[0163] In one way, when some resources of SMTC and STC overlap, the SSB transmission operation on the STC position is performed in the overlapping area, and the low-priority SMTC also performs measurement and discovery operations in the non-overlapping resources, corresponding to Figure 6 In the area outside the dotted rectangular box, the mobile terminal unit MT of the integrated access and backhaul link node IAB performs SSB measurement and discovery.

[0164] When the configuration period of SMTC and STC is the same, if the resources of the two are orthogonal, there is no priority issue. If the periods of the two are the same and there is overlap in resources, the integrated access and return link node IAB does not expect such a configuration; or the integrated access and return link node IAB considers it to be an incorrect configuration; or, in this case, there is no clear priority for whether to perform the SMTC or STC operation, and the operation to be performed is determined by the integrated access and return link node IAB itself.

[0165] Alternatively, regardless of the periodic relationship between the SMTC and the STC, no clear priority is defined, and the integrated access and backhaul link node IAB itself determines the operation to be performed.

[0166] Example 5: From the IAB behavior description: MT configures SSB and performs DU operations first

[0167] Figure 7 is a schematic diagram according to Example 5 of this application, such as Figure 7 As shown, when the synchronous broadcast block SSB of the mobile terminal unit MT of the same integrated access and backhaul link node IAB conflicts with the hard time domain resources of the distributed unit DU and the conflict position corresponds to the SSB transmission operation of the distributed unit DU, the SSB transmission operation of the distributed unit DU is executed first.

[0168] Example 6: Child MT configuration: The parent node configures the child MT configuration to avoid the resources of type group 1 of the child DU

[0169] Figure 8 is a schematic diagram according to Example 6 of this application, such as Figure 8 As shown, in this example, the synchronized broadcast block SSB is configured on the downlink resource of the first unit MT of the integrated access and backhaul link node IAB, and the position of the time domain overlap with the synchronized broadcast block SSB resource corresponds to the hard attribute of the distributed unit DU of the integrated access and backhaul link node IAB.

[0170] If the synchronization broadcast block SSB configured on the downlink resources of the first unit MT of the integrated access and backhaul link node IAB is used for downlink synchronization and downlink measurement of the service cell, the integrated access and backhaul link node IAB does not expect the time domain resources corresponding to its distributed unit DU to be configured as hard attributes. If the time domain resources corresponding to its distributed unit DU are configured as hard attributes, the integrated access and backhaul link node IAB shall give priority to executing the operation configured by the first unit MT; or the hard attributes shall be understood as soft resources in the frequency division multiplexing (FDM) or spatial division multiplexing (SDM) multiplexing mode, and the corresponding transceiver operation shall be executed according to the transmission direction corresponding to the operation configured by the first unit MT. For example, if the first unit MT executes the reception measurement of the synchronization broadcast block SSB, its distributed unit DU may schedule the uplink transmission or feedback of its child nodes.

[0171] If the synchronization broadcast block SSB is configured on the downlink resources of the first unit MT of the integrated access and backhaul link node IAB for neighboring cell synchronization and measurement, and the time domain resources corresponding to the distributed unit DU of the integrated access and backhaul link node IAB are configured as hard attributes, the integrated access and backhaul link node IAB performs the scheduling operation of the distributed unit DU regarding the hard corresponding transmission direction.

[0172] Figure 8 The random access channel RACH is configured on the resources of the first unit MT of the integrated access and backhaul link node IAB. The position where the time domain overlaps with the random access channel RACH resources corresponds to the hard attribute of the distributed unit DU of the integrated access and backhaul link node IAB.

[0173] If the random access channel RACH configured on the resources of the first unit MT of the integrated access and backhaul link node IAB is used for uplink synchronization or uplink measurement of the current service cell, the integrated access and backhaul link node IAB does not expect the time domain resources corresponding to its distributed unit DU to be configured as hard attributes. If configured as hard attributes, the integrated access and backhaul link node IAB shall give priority to executing the operations configured by the first unit MT; or in the frequency division multiplexing FDM (Frequency Division Multiplexing) or spatial division multiplexing SDM (Spatial Division Multiplexing) multiplexing mode, the hard attributes shall be understood as soft resources, and the corresponding transceiver operations shall be executed according to the transmission direction corresponding to the operations configured by the first unit MT. For example, if the first unit MT executes the transmission of random access RACH, its distributed unit DU may schedule the downlink transmission or downlink measurement of its child nodes.

[0174] The uplink measurement mentioned above means that the first unit MT sends a random access channel, and the receiver measures the uplink quality, uplink propagation channel and beam. The first unit MT sends the random access channel on the beam specified by the receiver.

[0175] The above-mentioned downlink measurement refers to the distributed unit DU sending a pilot or synchronization broadcast block SSB, and the sub-node receiver of the integrated access and backhaul link node IAB measures its downlink quality, downlink propagation channel and beam.

[0176] If the synchronization broadcast block SSB is configured on the downlink resources of the first unit MT of the integrated access and backhaul link node IAB for neighboring cell synchronization and measurement, and the time domain resources corresponding to the distributed unit DU of the integrated access and backhaul link node IAB are configured as hard attributes, the integrated access and backhaul link node IAB performs the scheduling operation of the distributed unit DU regarding the hard corresponding transmission direction.

[0177] If the random access channel RACH is configured on the resources of the first unit MT of the integrated access and backhaul link node IAB for random access and uplink measurement of neighboring cells, and the time domain resources corresponding to the distributed unit DU of the integrated access and backhaul link node IAB are configured as hard attributes, the integrated access and backhaul link node IAB performs the scheduling operation of the distributed unit DU regarding the transmission direction corresponding to the hard attribute.

[0178] If the system information SI (System Information) of the downlink resource configuration of the first unit MT of the integrated access and return link node IAB is transmitted, and the system information SI is transmitted periodically, the integrated access and return link node IAB does not expect the time domain resources corresponding to its distributed unit DU to be configured as hard attributes. If configured as hard attributes, the integrated access and return link node IAB shall give priority to executing the operations configured by the first unit MT; or in the frequency division multiplexing FDM (Frequency Division Multiplexing) or spatial division multiplexing SDM (Spatial Division Multiplexing) multiplexing mode, the hard attributes shall be understood as soft resources, and the corresponding transceiver operations shall be executed according to the transmission direction corresponding to the operations configured by the first unit MT. For example, the first unit MT executes system information reception, and its distributed unit DU may schedule the uplink transmission of its child nodes.

[0179] If the system information SI (System Information) of the downlink resource configuration of the first unit MT of the integrated access and return link node IAB is transmitted, and the system information SI is a combination of periodic transmission and on-demand transmission, and this transmission is a periodic system information SI transmission, if the distributed unit DU corresponding to the periodically transmitted system information SI is configured as a resource with hard attributes, the integrated access and return link node IAB shall prioritize the operation configured by the first unit MT.

[0180] If the downlink resource configuration of the first unit MT of the integrated access and return link node IAB is system information SI (System Information) transmission, and the system information SI is a combination of periodic transmission and on-demand transmission, and this transmission is periodic system information SI transmission, if the distributed unit DU corresponding to the periodically transmitted system information SI is configured as a resource with hard attributes, the integrated access and return link node IAB shall prioritize the scheduling of the distributed unit DU on its child nodes.

[0181] If the system information SI (System Information) of the downlink resource configuration of the first unit MT of the integrated access and return link node IAB is transmitted, and the system information SI is periodically transmitted, and this transmission is a periodic system information SI transmission, if the distributed unit DU corresponding to the periodically transmitted system information SI is configured as a resource with a hard attribute, the integrated access and return link node IAB shall prioritize the operation configured by the first unit MT.

[0182] The resource configuration of the distributed unit DU and the transmission configuration of the first unit MT within the same node in the figure are only for the convenience of example description and do not limit the combination of the resources of the distributed unit DU and the transmission configuration of the first unit MT within the same node of the present invention.

[0183] Example 7: DU soft can be used for type 2 signal and channel transmission

[0184] This example describes the operation behavior of the integrated access and backhaul link node IAB corresponding to a given configuration relationship between the distributed unit DU and the first unit MT. Figure 9 This is an example according to Example 7 of this application Figure 1 ,like Figure 9 As shown, some resources of the integrated access and return link node IAB are configured as soft attributes, and these soft resources are further indicated as Available by the parent node. Then, these resources indicated as Available can be used by the integrated access and return link node IAB node for signal and channel transmission of the next-level child node or the next-level terminal.

[0185] Furthermore, if the soft resources of the distributed unit DU are further indicated as available, the integrated access and backhaul node IAB expects to use these resources to schedule the type 2 signal and channel of the first unit or terminal.

[0186] When the resource attribute of a distributed unit (DU) is soft and the parent node explicitly signals the DU as available, and the transmission direction of the resource is downlink, the resource can be used for downlink control channel transmission of the child node or terminal.

[0187] When the resource attribute of a distributed unit (DU) is soft and the parent node explicitly signals the DU as available, and if the transmission direction of this resource is downlink, this resource can be used for downlink traffic channel transmission of the child node or terminal. Specifically, it can be used for downlink non-broadcast traffic data transmission of the child node.

[0188] When the resource attribute of a distributed unit (DU) is soft and the parent node explicitly signals the DU as available, and if the transmission direction of this resource is downlink, this resource can be used to transmit downlink pilot signals to child nodes or terminals. The child nodes receive the pilot signals to measure channel quality and beamforming.

[0189] When the resource attribute of a distributed unit (DU) is soft and the parent node explicitly signals the DU as available, if the transmission direction of this resource is uplink, this resource can be used to schedule uplink traffic channel transmissions of child nodes or terminals. Furthermore, the uplink traffic channel can also be used to carry aperiodic channel condition feedback.

[0190] When the resource attribute of a distributed unit DU is soft and the soft attribute of the distributed unit DU is notified as available by the parent node through explicit signaling, if the transmission direction of this resource is uplink, this resource can be used to schedule the uplink sounding reference signal (SRS) of the child node or terminal.

[0191] As an integrated access and backhaul node, the IAB can also implicitly determine the availability of soft resources for the distributed unit (DU). One method is to determine whether the first MT corresponding to the soft resources of the distributed unit (DU) is scheduled by the parent node. If not, the IAB determines that the soft resources of the distributed unit (DU) are available for scheduling by its next-level node or terminal. The signals and channels scheduled are similar to those used in the explicit determination of soft resource availability, and are not further described.

[0192] The locations of the soft resources of the distributed unit DU and the corresponding combinations of its subnodes in the accompanying figures are merely for the convenience of describing examples and do not limit the present invention. The subsequent figures are also merely for illustrative purposes and do not limit the corresponding relationships between the soft resource locations of the distributed unit DU and the signal channels of its subnodes in the present invention. Subsequent examples will not be separately stated.

[0193] Example 8: Implicit indication of soft resource availability (MT priority signal implicitly indicates DU soft)

[0194] In this example, the status of the location of the soft resource of the distributed unit DU is determined as follows:

[0195] Figure 10 This is an example according to Example 8 of this application Figure 1 ,like Figure 10 As shown, when the first unit MT of the integrated access and backhaul link node IAB is configured as the type 1 signal and channel of the first unit MT described in Example 1, the soft resources of the distributed unit DU that the integrated access and backhaul link node IAB does not expect to overlap with the type 1 signal and channel of the first unit MT are indicated as Available.

[0196] Furthermore, when the DU resource configuration at the time domain resource position corresponding to the synchronous broadcast block SSB of the first unit MT of the integrated access and return link node IAB is soft and this resource is further indicated as Available by the upper-level node, the integrated access and return link node IAB determines that these resources are Not Available (NA) for the DU, that is, the integrated access and return link node IAB determines that this is an erroneous indication, when the integrated access and return link node IAB performs type 1 signal and channel operations on the first unit MT.

[0197] Type 1 signals and channels of the first unit MT include:

[0198] Synchronization signal used for downlink synchronization or downlink measurement;

[0199] Pilot signal used for downlink synchronization or downlink measurement;

[0200] Random access channel used for uplink synchronization or uplink measurement;

[0201] Pilot signal used for uplink synchronization or uplink measurement;

[0202] A channel for transmitting system information.

[0203] Example 9: Implicit indication of soft resource availability (MT non-priority signal is DU)

[0204] In this example, the status of the location of the soft resource of the distributed unit DU is determined as follows:

[0205] When the first MT of the integrated access and backhaul node IAB is configured for transmission outside of the type 2 signal and channel of the first MT described in Example 1, the integrated access and backhaul node IAB expects that the soft resources of the distributed unit DU that overlaps with the type 2 signal and channel of the first MT will be indicated as available. If the soft resources of the distributed unit DU that overlaps with the type 2 signal and channel of the first MT are indicated as available, the integrated access and backhaul node IAB determines that the resources indicated as available are valid for the distributed unit DU and terminates the transmission configuration on the MT.

[0206] Example 10: MT Type 1 signal, channel, and DU resources with overlapping soft and hard resources

[0207] Figure 11 is a schematic diagram according to Example 10 of the present application, such as Figure 11 As shown, when the type 1 signal and channel of the mobile terminal node MT of the integrated access and backhaul link node IAB overlap with the soft resources of the distributed unit DU or overlap with the hard resources of the distributed unit DU or overlap with both the soft and hard resources in the time domain, the IAB performs the MT operation on the resources where the type 1 signal and channel are located and the soft resources of the distributed unit DU are invalid resources within a certain time interval of the type 1 signal and channel of the mobile terminal node MT and the termination of the mobile terminal MT operation.

[0208] The above time interval is notified by the parent node through high-layer signaling; or the corresponding time interval is agreed upon according to the capability reported by the child node; or the child node reports the expected time interval, and the parent node confirms the reported expected value.

[0209] Example 11: Explicit determination of soft resource availability

[0210] The validity of the soft resources of the distributed unit DU of the integrated access and backhaul link node IAB is determined by explicit signaling;

[0211] The availability of soft resources is notified through downlink control information (DCI) signaling and needs to be confirmed through explicit signaling;

[0212] The default method for determining soft resource availability is explicit signaling.

[0213] The explicit signaling includes a default value.

[0214] Specific rules include:

[0215] When higher-layer signaling notifies the user to use explicit signaling to determine the availability of soft resources for the distributed unit (DU) of the integrated access and backhaul node (IAB), the higher-layer signaling also notifies the user to use explicit signaling to determine the availability of soft resources at a specified time. The time can be from the issuance of the higher-layer signaling to the next update of the higher-layer signaling, or a certain time offset from the issuance of the higher-layer signaling to the next update of the higher-layer signaling.

[0216] When the integrated access and backhaul node IAB receives a DCI indicating the availability of soft resources of the distributed unit DU, it is considered that explicit signaling is used to determine the availability of soft resources during the period from the receipt of the downlink control information DCI to the time period indicated by the DCI.

[0217] The integrated access and backhaul link node IAB determines the validity of the soft resource according to the received downlink control information DCI within the time period. If no indication indicating the soft resource is received within the time period, the attribute of the soft resource is determined to be a default value, such as an unavailable NA attribute.

[0218] Example 12: Implicit determination of soft resource availability W default value

[0219] The soft resource validity of the distributed unit DU notified to the integrated access and backhaul node IAB through high-layer signaling is determined implicitly, or implicitly by default in a predetermined manner. The implicit determination includes a default value.

[0220] Implicit signaling determines the availability of soft resources of the corresponding distributed unit DU through the integrated access and backhaul link node IAB to determine whether its first unit MT has the corresponding signal and channel scheduling.

[0221] The signals and channels here include

[0222] Uplink traffic channel;

[0223] Uplink control channel;

[0224] Downlink control channel;

[0225] Dynamically schedule downlink traffic channels carrying terminal services through control channels;

[0226] Downlink pilot;

[0227] Uplink pilot;

[0228] The actual received sync broadcast blocks;

[0229] Random access signal;

[0230] The downlink traffic channel that carries system information is dynamically scheduled through the control channel.

[0231] If the first unit MT of the integrated access and backhaul link node IAB does not transmit the above-mentioned signals and channels, the soft resources of the corresponding distributed unit are determined to be available. When its first unit MT has the above-mentioned signal and channel transmission scheduling, the integrated access and backhaul link node IAB performs the operation on the first unit MT; if the above-configured transmission distributed unit DU determines that it can not perform transmission and reception operations, the integrated access and backhaul link node IAB determines that the corresponding DU resources are available.

[0232] If the first unit MT of the integrated access and backhaul link node IAB transmits signals and channels other than the above signals and channels, it is determined that the soft resources of the corresponding distributed unit are default values, such as not available NA.

[0233] Example 13: Soft resource availability determination

[0234] The soft resource validity of the distributed unit DU notified to the integrated access and backhaul node IAB through high-layer signaling is determined implicitly, or implicitly by default in a predetermined manner. The implicit determination includes a default value.

[0235] Implicit signaling determines the availability of soft resources of the corresponding distributed unit DU through the integrated access and backhaul link node IAB to determine whether its first unit MT has the corresponding signal and channel scheduling.

[0236] The signals and channels here include

[0237] Uplink traffic channel;

[0238] Uplink control channel;

[0239] Downlink control channel;

[0240] Dynamically schedule downlink traffic channels carrying terminal services through control channels;

[0241] Downlink pilot;

[0242] Uplink pilot;

[0243] The actual received sync broadcast blocks;

[0244] Random access signal;

[0245] The downlink traffic channel that carries system information is dynamically scheduled through the control channel.

[0246] If the first unit MT of the integrated access and backhaul link node IAB does not transmit the above-mentioned signals and channels, the soft resources of the corresponding distributed unit are determined to be available. When its first unit MT has the above-mentioned signal and channel transmission scheduling, the integrated access and backhaul link node IAB performs the operation on the first unit MT; if the above-configured transmission distributed unit DU determines that it can not perform transmission and reception operations, the integrated access and backhaul link node IAB determines that the corresponding DU resources are available.

[0247] If the first unit MT of the integrated access and backhaul link node IAB transmits signals and channels other than the above signals and channels, it is determined that the soft resources of the corresponding distributed unit are default values, such as not available NA.

[0248] Example 14: Soft resource availability determination

[0249] The validity of the soft resources of the integrated access and backhaul link node (IAB) is determined by a combination of explicit signaling and implicit methods, where the implicit determination does not include the default value.

[0250] Implicit signaling determines the availability of soft resources of the corresponding distributed unit DU through the integrated access and backhaul link node IAB to determine whether its first unit MT has the corresponding signal and channel scheduling.

[0251] The signals and channels here include all signal channels, including uplink and downlink services, control, downlink simultaneous broadcast, uplink random access, and uplink and downlink pilots. Whenever any signal or channel is being transmitted or received, the first MT's operation is prioritized, and the soft resources of the distributed unit (DU) are determined to be unavailable (NA). Otherwise, if none of the above resources need to be transmitted or received, the DU's soft resources are determined to be available (Available).

[0252] Example 15: Soft resource availability determination

[0253] The validity of the soft resources of the integrated access and backhaul link node (IAB) is determined by a combination of explicit signaling and implicit methods, where the explicit signaling includes a default value.

[0254] Or when there is no explicit notification in the default agreement, the validity of the soft resources of the integrated access and backhaul link node IAB node is determined by combining explicit signaling and implicit methods.

[0255] The validity of soft resources should be determined by combining the results of explicit and implicit judgments to determine the final status of soft resources.

[0256] One way to judge is that the explicitly indicated state always takes precedence:

[0257] Figure 12 This is a schematic diagram based on Example 15 of this application Figure 1 ,like Figure 12 As shown, the result of the explicit indication, whether it is the explicit signaling indication Explicit or the default value Default, determines the final state of the soft resource.

[0258] Figure 13 This is a schematic diagram based on Example 15 of this application Figure 2 ,like Figure 13 The following judgment method shows that the default NA can be judged as available by the implicit method Implicit.

[0259] Figure 14 This is a schematic diagram based on Example 15 of this application Figure 3 ,like Figure 14 As shown, one way of judging is that it is explicitly available A and the other way is that it is implicitly judged as unavailable NA.

[0260] For example, if some high-priority signals and channels need to be sent or received on the first unit MT, the soft resources of the distributed unit will be determined to be unavailable. The high-priority signals and channels include those used by the first unit MT for uplink and downlink synchronization and measurement.

[0261] Figure 15 This is a schematic diagram based on Example 15 of this application Figure 4 ,like Figure 15 As shown, one judgment method is to give priority to implicit indications based on explicit signaling indications rather than default value indications.

[0262] Figure 16This is a schematic diagram based on Example 15 of this application Figure 5 ,like Figure 16 As shown, one judgment method is that the explicit Not Available (NA) can be overwritten by the implicit Available.

[0263] like Figure 16 As shown, even though the soft resource is indicated as NotAvailable by explicit signaling rather than by default, it is implicitly determined to be Available (A). For example, if the parent node explicitly indicates the soft resource as Available through signaling, but the relay node implicitly determines that there is no transmission of the first unit at this location, the relay node still determines that the soft resource of the second unit is available and performs uplink or downlink scheduling on the corresponding soft resource of the second unit.
