It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein and that "first" and "second" distinguish objects. It is usually one category, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the description and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

In order to facilitate the understanding of the embodiments of the present application, the following contents are first described.

Please refer to FIG. 1 . FIG. 1 shows a schematic diagram of an IAB system applicable to an embodiment of the present application. In the IAB system, an IAB node includes an MT functional part and a DU functional part. Relying on MT, an IAB node can find one/multiple parent IAB nodes (parent IAB node, or upstream IAB node), and establish a wireless connection with the DU of the parent IAB node. This wireless connection is called a backhaul link (backhaul link). After an IAB node establishes a complete backhaul link, the IAB node can enable its DU function, and the DU will provide cell services, that is, the DU can provide access services for user equipment (User Equipment, UE). A self-backhaul loop contains one/multiple donor IAB nodes (or called IAB donor), and the donor IAB nodes have a directly connected wired transmission network. It should be pointed out that an example with one parent IAB node and one donor IAB node is shown in FIG. 1 , but this embodiment of the application is not limited thereto.

Fig. 2 is a schematic structural diagram of a control unit-distributed unit (Centralized Unit-Distributed Unit, CU-DU) of the IAB system in the embodiment of the present application. In a self-backhaul loop, all DUs of the IAB nodes are connected to a CU node, and the CU node configures the DUs through the F1 application (F1-Aplication, F1-AP) protocol. The CU configures the MT through the Radio Resource Control (RRC) protocol. Donor IAB node does not have MT functional part.

In the embodiment of the present application, the duplexing mode between the DU and the MT of the IAB node is divided into half duplex (Half duplex) and full duplex (Full duplex) modes. In the case of Full duplex, DU/MT can send and receive at the same time.

Optionally, when the DU and MT of the IAB node are multiplexed in a time-division multiplexing (Time Domain Multiplexing, TDM) manner, the transceiving operation of the DU and the transceiving operation of the MT are time-division multiplexed (TDMed). The duplex mode at this time is half duplex.

Optionally, when the DU and MT of the IAB node are multiplexed in frequency division multiplexing (Frequency Domain Multiplexing, FDM) or space division multiplexing (Space Domain Multiplexing, SDM), the sending and receiving operation modes of DU and MT include but not Limited to at least one of the following duplex methods:

1) DU-TX&MT-TX; that is, DU is configured as downlink (Downlink, DL), MT is configured as uplink (Uplink, UL); or, DU has actual DL transmission, and MT has actual UL transmission;

2) DU-RX&MT-RX; that is, DU is configured as UL, and MT is configured as DL; or, DU has actual UL reception, and MT has actual DL reception;

3) DU-TX&MT-RX; that is, DU is configured as DL, and MT is configured as DL; or, DU has actual DL transmission, and MT has actual DL reception;

4) DU-RX&MT-TX; that is, the DU is configured as UL, and the MT is configured as UL; or, the DU has actual UL reception, and the MT has actual UL transmission.

It should be pointed out that in the embodiment of this application, DU TX and DU DL can be used in common, MT TX and MT UL can be used in common, DU RX and DU UL can be used in common, and MT RX and MT DL can be used in common.

It can be understood that in the embodiment of the present application, the three multiplexing modes of TDM, SDM and FDM all involve coordinated scheduling between hops. The description of these three multiplexing methods is as follows:

1) Time Division Multiplexing (TDM) means that one IAB node operates IAB MT and IAB DU on different time domain resources. For example, an IAB MT receives a Physical Downlink Shared Channel (PDSCH) from its parent IAB node on a certain time domain resource or sends a Physical Uplink Shared Channel (PUSCH) to its parent IAB node; IAB DU Receive PUSCH from its child IAB node or UE or send PDSCH to its child IAB node or UE on another time domain resource.

2) Space Division Multiplexing (SDM) means that an IAB node operates IAB MT and IAB DU on the same time-frequency resource. For example, IAB MT receives PDSCH from its parent IAB node or sends PUSCH to its parent IAB node, and IAB DU receives PUSCH from its child IAB node or UE or sends PDSCH to its child IAB node or UE, in the same time-frequency domain resource transfer.

3) Frequency division multiplexing (FDM) means that an IAB node simultaneously operates IAB MT and IAB DU on different frequency resources. For example, IAB MT receives PDSCH from its parent IAB node or sends PUSCH to its parent IAB node, and IAB DU receives PUSCH from its child IAB node or UE or sends PDSCH to its child IAB node or UE, in the same time domain resource upload.

In the embodiment of the present application, the involved full duplex (Full Duplex) scenarios include: DU-TX&MT-RX and DU-RX&MT-TX. For example, full duplex can mean that an IAB node receives PDSCH from its parent IAB node and sends PDSCH to its child IAB node or UE at the same time, or an IAB node sends PUSCH and Receive PUSCH from its child IAB node or UE.

Optionally, for the resource configuration of the IAB DU, the Donor node CU can configure the time domain resources of the DU through F1-AP (or F1-C) signaling such as gNB-DU resource configuration. Wherein, the type of symbol (symbol) transmission (or symbol transmission direction) in each time slot is configured, and the symbol type (or symbol direction) includes DL symbol, UL symbol and flexible (flexible) symbol. Configure the availability of each type of symbol of the DU, including hard (hard)/soft (soft)/not available (Not Available) type configuration. Availability is configured in units of symbol types. specific,

- If the DL/UL/flexible symbol is configured as hard, the IAB DU can be sent/received/sent or received on the symbol;

- If the DL/UL/flexible symbol is configured as soft, and the transmission/reception/transmission or reception of the IAB DU does not affect the transmission or reception of the MT, the IAB DU can be transmitted/received/transmitted or received on the symbol; otherwise, The IAB DU does not transmit/receive/transmit or receive on this symbol. Further, the IAB parent node can indicate the availability of the soft symbol of the IAB DU.

- If the DL/UL/flexible symbol is configured as Not Available (NA), then the IAB DU will not be sent or received on this symbol.

Optionally, for the resource configuration of the IAB MT, the time domain resources of the IAB MT are configured by the CU/parent IAB node, which can be configured through TDD config and downlink control information (Downlink Control Information, DCI) in RRC signaling. The symbol type of IAB MT is DL/UL/Flexible symbol. Further, DCI format 2_0 (format 2_0) can dynamically rewrite resources configured as flexible symbols, or can dynamically rewrite resources configured as flexible symbols through a configured grant.

Optionally, in the embodiment of this application, the resource schemes for IAB MT and IAB DU may include at least the following five types:

Solution 1: The resource configuration and/or indication of the IAB MT is a flexible resource, and the resource configuration and/or indication of the IAB DU is a DL resource;

Scheme 2: The resource configuration and/or indication of IAB MT is flexible resource, and the resource configuration and/or indication of IAB DU is UL resource;

Scheme 3: The resource configuration and/or indication of IAB MT is DL resource, and the resource configuration and/or indication of IAB DU is flexible resource;

Solution 4: The resource configuration and/or indication of IAB MT is UL resource, and the resource configuration and/or indication of IAB DU is flexible resource;

Solution 5: The resource configuration and/or indication of the IAB MT is a flexible resource, and the resource configuration and/or indication of the IAB DU is a flexible resource.

It should be pointed out that in the above schemes 1 to 5, the resources of the IAB MT correspond to the resources of the IAB DU. This correspondence can be understood as the same time domain resources, and the frequency domain resources are not limited. The resource of IAB MT may include but not limited to symbol, time slot slot, frame frame, etc. The resource of IAB DU may include but not limited to symbol, time slot slot, frame frame, etc.

Under Scheme 1, Scheme 2 and Scheme 5, the transmission direction of IAB MT/DU can be determined according to at least one of the following: priority relationship of IAB MT/DU, multiplexing capability of IAB node, signaling indication, transmission direction of IAB DU . Under scheme three, scheme four and scheme five, the transmission direction of IAB MT/DU can be determined according to at least one of the following: priority relationship of IAB MT/DU, multiplexing capability of IAB node, signaling indication, transmission of IAB MT direction.

In the embodiment of the present application, different transmission behaviors may be adopted for different signals/channels. For example, for UL transmission, in case of collision, only the transmission of the conflicting symbols can be canceled for Sounding Reference Signal (SRS), and the SRS on the remaining symbols can be transmitted; for the Physical Uplink Control Channel (Physical Uplink Control Channel, For PUCCH)/PUSCH/Physical Random Access Channel (PRACH) transmission, if some symbols collide, the entire PUCCH/PUSCH/PRACH transmission can be canceled. For DL transmission, for DL positioning reference signal (Positioning Reference Signal, PRS) transmission, if the high-level scheduling is received in the flexible symbol, it can be received; if the high-level scheduling physical downlink control channel (Physical Downlink Control Channel, PDCCH)/PDSCH/ If the Channel State Information-Reference Signal (CSI-RS) is received on the flexible symbol, it may not be received.

It should be pointed out that in the embodiment of this application, the MT of the IAB node can be abbreviated as IAB MT, and the DU of the IAB node can be abbreviated as IAB DU.

The resource processing method provided by the embodiment of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

Please refer to FIG. 3. FIG. 3 is a flowchart of a resource processing method provided in an embodiment of the present application. The method is executed by an IAB node. As shown in FIG. 3, the method includes the following steps:

Step 31: The IAB node receives scheduling signaling from the parent IAB node.

Optionally, the above scheduling signaling may be used for scheduling of MTs of the IAB node. The foregoing scheduling signaling may be MT/DU scheduling signaling of the IAB node. For example, the foregoing scheduling signaling may be DCI or the like.

In one embodiment, the parent IAB node can determine the scheduling signaling for scheduling the IAB MT according to the content reported by the IAB node and/or the capabilities of the IAB node.

Step 32: The IAB node determines whether the MT of the IAB node is scheduled on the first resource according to the scheduling signaling.

Optionally, the first resource is a resource configured by the IAB MT and/or indicated as a UL resource (corresponding to the above-mentioned scheme 4), a DL resource (corresponding to the above-mentioned scheme 3) or a flexible resource (corresponding to the above-mentioned scheme 5). The first resource corresponds to the second resource, and the second resource is a configuration of the IAB DU and/or a resource indicated as a flexible resource. The correspondence between the first resource and the second resource may be understood as: the first resource and the second resource are the same time-domain resources such as symbols. The frequency domain resources of the first resource and the second resource are not limited, and may be the same or different.

Optionally, the first resource includes but not limited to symbol, slot, frame, microsecond, millisecond, second, etc., and the second resource includes but not limited to symbol, slot, frame, microsecond, millisecond, second, etc. A resource and a second resource are constrained.

In the resource processing method of the embodiment of the present application, the IAB node can receive scheduling signaling from the parent IAB node, and according to the scheduling signaling, determine whether the MT of the IAB node has scheduling on the first resource; the first resource is the MT configuration and/or resources indicated as UL resources, DL resources or flexible resources; the first resource corresponds to the second resource, and the second resource is the configuration of the DU of the IAB node and/or indicated as flexible resources resource. Therefore, when the corresponding resources of MTs and/or DUs of the IAB node are configured as flexible resources, the scheduled transmission of MTs and/or DUs can be specified, so that the understanding of MTs and DUs is consistent, and the efficiency of system transmission is ensured. Furthermore, simultaneous transmission of IAB MT and IAB DU on flexible resources can also be achieved, thereby improving resource utilization.

In one embodiment, in the above scheme three, that is, at a certain moment, the resources of the IAB MT are DL resources, and the resources of the IAB DU are flexible resources. According to the DCI indication obtained in advance, the IAB node can determine whether the IAB MT is scheduled on the corresponding DL resource, where the corresponding DL resource is the same time-domain resource as the Flexible resource of the IAB DU. Or, the IAB node can determine whether the IAB MT is scheduled on the corresponding DL resource according to the sending/receiving of the configuration acquired in advance. Among them, the transmission/reception of the above configuration, or the scheduling indicated by DCI, may refer to Synchronization Signal and PBCH block (SSB)/type 0 search space (type 0 search space)/PDCCH/PDSCH/CSI-RS/DL Reception of PRS. If the IAB MT is not configured to detect DCI format 2-0, at least the reception of the SSB can be determined for the configured transmission/reception. The transmission and reception of other high-level configurations will be changed by the DCI, but it can be stipulated that the transmission and reception of a certain high-level configuration cannot be changed by the DCI.

In one embodiment, the above scheme three or scheme four, for a certain point in time, the time division duplex (TDD) direction of IAB MT is DL/UL, and the TDD direction of IAB DU is flexible (can be abbreviated as F):

(1) If the IAB MT priority is predefined, preconfigured and/or configured, at least one of the following is met:

1) Regardless of whether the DU resource type configuration allows IAB DU scheduling, IAB DU cannot be scheduled.

2) IAB DU is scheduled in a conservative way, that is, it cannot affect the behavior/performance of IAB MT reception; parent IAB has a certain aggressiveness when scheduling IAB MT.

Optionally, for the aggressiveness of parent IAB scheduling: parent IAB node scheduling can assume that IAB DU is not scheduled; or, parent IAB node scheduling can assume that IAB DU scheduling is UL/DL.

Optionally, when IAB DU is scheduled, it can be assumed that there is IAB MT scheduling. Moreover, IAB MT scheduling can assume that IAB DU is not scheduled; or, IAB MT scheduling can assume that IAB DU scheduling is UL/DL.

Optionally, if the parent IAB node knows in advance whether MT is scheduled or not, it can increase the aggressiveness of IAB DU scheduling accordingly. For determining whether there is scheduling, whether there is scheduling can be determined according to the DCI indication obtained in advance, or whether there is scheduling can be determined according to the configured transmission/reception (configured transmission/reception) obtained in advance, wherein the IAB MT is not configured as On the premise of detecting DCI format 2-0, at least the reception of SSB can be confirmed. The transmission and reception of other high-level configurations will be changed by DCI, but it can be newly stipulated that the transmission and reception of a certain high-level configuration cannot be changed by DCI.

(2) If the IAB DU priority is predefined, preconfigured and/or configured, at least one of the following is met:

1) At least when the DU resource type configuration allows IAB DU scheduling, the Parent IAB node cannot schedule IAB MT.

2) The parent IAB node adopts conservative scheduling when scheduling IAB MT, that is, it cannot affect the sending behavior/performance of IAB DU scheduling; IAB DU scheduling has a certain scheduling aggressiveness.

Optionally, the parent IAB node cannot determine whether the flexible resource of the IAB DU is scheduled, and/or the parent IAB node cannot determine that the scheduling on the flexible resource of the IAB DU is UL/DL; the parent IAB node defaults that the IAB DU can be used as any UL/DL DL scheduling.

Optionally, if the parent IAB node can determine whether the flexible resource of the IAB DU is scheduled, and/or determine that the scheduling on the flexible resource of the IAB DU is UL/DL, the parent IAB node performs scheduling according to the scheduling direction of the IAB DU. For example, IAB DU can report scheduling plan/scheduling direction/multiplexing case, etc.

Optionally, when IAB DU scheduling, at least one of the following assumptions must be met:

When IAB DU is scheduled as UL on flexible resources, it is assumed that MT DL & DU UL are performed simultaneously;

When IAB DU is scheduled as DL on flexible resources, it is assumed that MT DL & DU DL are performed simultaneously;

When IAB DU is scheduled on flexible resources, it is assumed that IAB MT is not scheduled;

Which of the above assumptions to use depends on the duplexing capability of the IAB.

(3) If there is no priority relationship between IAB MT and IAB DU, IAB MT and IAB DU can be scheduled according to the agreed multiplexing case. For example, always assume simultaneous sending or receiving, or determine the multiplexing case between IAB MT and IAB DU according to the multiplexing mode (multiplexing mode) indication of CU/parent, or determine the multiplexing case between IAB MT and IAB DU according to the expected multiplexing mode reported by IAB between multiplexing cases.

In another implementation manner, in the above scheme four, that is, at a certain moment, the resources of the IAB MT are UL resources, and the resources of the IAB DU are flexible resources. According to the DCI indication obtained in advance, the IAB node can determine whether the IAB MT is scheduled on the corresponding UL resource, where the corresponding UL resource is the same time-domain resource as the Flexible resource of the IAB DU. Or, the IAB node may determine whether the MT is scheduled on the corresponding UL resource according to the sending/receiving of the configuration acquired in advance. Wherein, the sending/receiving of the above configuration, or the scheduling indicated by the DCI may refer to the sending of PRACH/PUCCH/PUSCH/SRS.

It should be pointed out that under the above scheme five, that is, at a certain moment, the resources of IAB MT are flexible resources, and the resources of IAB DU are flexible resources. If the default or assumed flexible resources of IAB MT are DL resources, since the resources of IAB DU are flexible resources, it is similar to scheme three, and the corresponding method is the same as that in scheme three. However, if the flexible resources of the IAB MT are UL resources by default or assumed, since the resources of the IAB DU are flexible resources, it is similar to scheme 4, and the corresponding method is the same as that in scheme 4.

In the embodiment of this application, when the flexible resources of the IAB DU are converted into UL resources or DL resources, the IAB MT can send/receive/not send/not receive according to the scheduling signaling and/or the multiplexing mode of the IAB node, etc. . For the sending/receiving behavior of the IAB MT, if the scheduling behavior of the parent IAB node depends on the implementation after the IAB node reports the information, then the sending/receiving behavior of the IAB MT may need to be defined to avoid conflicts with the IAB DU.

Optionally, the IAB MT may perform the first operation on the third resource. Wherein, the third resource is a resource corresponding to the fourth resource among the first resources. The fourth resource is a resource converted into a UL resource or a DL resource among the second resources. The first operation includes at least one of the following: sending, receiving, not sending, not receiving. In this way, the transmission behavior of IAB MT can be further standardized, thereby improving resource utilization.

Optionally, for performing the first operation on the third resource, if the first condition is met, the IAB MT may perform at least one of the following:

no reception on the third resource;

not receiving on overlapping resources of the third resource and the fourth resource;

Receiving is performed on a third resource.

Wherein, the first condition may include at least one of the following:

1) The third resource configuration and/or indication is a DL resource, or the third resource configuration and/or indication is a flexible resource and the default third resource is a DL resource, and the fourth resource is a DL resource, and the configuration and/or indication The MT performs DL reception on the third resource;

2) The third resource configuration and/or indication is a DL resource, or the third resource configuration and/or indication is a flexible resource and the default third resource is a DL resource, and the fourth resource is a UL resource, and the configuration and/or indication The MT performs DL reception on the third resource.

Optionally, considering the duplex mode of IAB MT and IAB DU, the above-mentioned reception on the third resource may include: when the IAB node supports the reception of MT and the transmission of DU at the same time, or the IAB node supports the reception of MT and the transmission of DU When receiving simultaneously, the IAB MT receives on the third resource. In this way, the receiving behavior of IAB MT can be further standardized, thereby improving resource utilization.

Optionally, for performing the first operation on the third resource, if the second condition is met, the IAB MT may also perform at least one of the following:

no sending on the third resource;

Not sending on overlapping resources of the third resource and the fourth resource;

Sending is performed on the third resource.

Wherein, the second condition may include any of the following:

1) The third resource configuration and/or indication is a UL resource, or the third resource configuration and/or indication is a flexible resource and the default third resource is a UL resource, and the fourth resource is a DL resource, and the configuration and/or indication The MT performs UL transmission on the third resource;

2) The third resource configuration and/or indication is a UL resource, or the third resource configuration and/or indication is a flexible resource and the third resource is a UL resource by default, and the fourth resource is a UL resource, and the configuration and/or indication The MT performs UL transmission on the third resource.

Optionally, considering the duplex mode of IAB MT and IAB DU, the above-mentioned sending on the third resource may include: when the IAB node supports the sending of MT and the receiving of DU at the same time, or the IAB node supports the sending of MT and the receiving of DU When sending simultaneously, the IAB MT sends on the third resource. In this way, the sending behavior of IAB MT can be further standardized, thereby improving resource utilization.

It should be noted that the overlapping resources of the third resource and the fourth resource mentioned above may refer to the same resources in the time domain. For example, the third resource occupies symbol 1-8, and the fourth resource occupies symbol 4-10, then the resource whose time domain is the same as that of the third resource and the fourth resource, that is, the overlapping resource is symbol 4-8.

For example, taking the first resource and the second resource as symbols as an example, if some/all of the flexible symbols in the configuration of the IAB DU and/or indicated flexible symbols are converted into DL symbols, the IAB MT can know which flexible symbols of the IAB DU The direction of has changed, which belongs to the internal implementation of the IAB node, then:

1) The symbol configured and/or indicated in IAB MT is DL symbol (corresponding to the above scheme 3), or the configuration and/or indicated symbol of IAB MT is flexible symbol (corresponding to scheme 5 above) and is defaulted to DL symbol In the case of , if the high-level configuration/DCI instructs the IAB MT to perform DL transmission/reception on the corresponding symbol, the IAB MT does not receive the corresponding transmission; or, the IAB MT does not receive on the corresponding overlapping symbols, which satisfies the semi-double or, the IAB MT receives on the corresponding symbol. Among them, when the IAB node supports simultaneous operation of MT reception and DU transmission, it supports IAB MT to receive on the corresponding symbol.

2) The symbol configured and/or indicated by the IAB MT is a UL symbol (corresponding to the above scheme 4), or the configuration and/or indicated symbol of the IAB MT is a flexible symbol (corresponding to the above scheme 5) and is defaulted to the UL symbol In the case of , if the high-level configuration/DCI instructs the IAB MT to perform UL transmission/send on the corresponding symbol, the IAB MT will not send the corresponding transmission; or, the IAB MT will not send on the corresponding overlapping symbols, which is a new behavior. It is equivalent to disabling simultaneous operation that does not affect IAB DU; or, IAB MT sends on the corresponding symbol. Among them, when the IAB node supports simultaneous operation of MT transmission and DU transmission, it supports IAB MT to transmit on the corresponding symbol. For example, if part of the SRS symbol falls on the symbol from DU flexible to DL, the SRS on the overlapping overlap symbol will not be sent, but the non-overlap SRS symbol can be sent.

As another example, taking the first resource and the second resource as symbols as an example, if the configuration of the IAB DU and/or some/all of the indicated flexible symbols are converted to UL symbols, then:

1) The symbol configured and/or indicated in IAB MT is DL symbol (corresponding to the above scheme 3), or the configuration and/or indicated symbol of IAB MT is flexible symbol (corresponding to scheme 5 above) and is defaulted to DL symbol In the case of , if the high-level configuration/DCI instructs the IAB MT to perform DL transmission/reception on the corresponding symbol, the IAB MT does not receive the corresponding transmission; or, the IAB MT does not receive on the corresponding overlapping symbols, which satisfies the semi-double or, the IAB MT receives on the corresponding symbol. Among them, when the IAB node supports simultaneous operation of MT reception and DU reception, it supports IAB MT reception on the corresponding symbol.

2) The symbol configured and/or indicated by the IAB MT is a UL symbol (corresponding to the above scheme 4), or the configuration and/or indicated symbol of the IAB MT is a flexible symbol (corresponding to the above scheme 5) and is defaulted to the UL symbol In the case of , if the high-level configuration/DCI instructs the IAB MT to perform UL transmission/transmission on the corresponding symbol, the IAB MT does not transmit the corresponding transmission; or, the IAB MT does not transmit on the corresponding overlapping symbol; or, the IAB MT does not transmit on the corresponding symbol Send on the corresponding symbol. Among them, when the IAB node supports simultaneous operation of MT transmission and DU transmission, it supports IAB MT to transmit on the corresponding symbol.

In the embodiment of the present application, the scheduling of the IAB MT and the scheduling of the IAB DU may be related to whether the IAB MT is prioritized or the IAB DU is prioritized in the transmission of the IAB node. Whether IAB MT priority or IAB DU priority can be determined according to a preset method, or it can be defaulted (or called as assumption) that IAB MT priority or IAB DU priority is the default.

(1) Optionally, when the first resource is configured and/or indicated as a DL resource (corresponding to the above scheme 3), or the first resource is configured and/or indicated as a flexible resource (corresponding to the above scheme 5) and the first resource is defaulted In the case of DL resources:

And/or, 2) The scheduling of IAB MT can satisfy:

The IAB MT is scheduled with no transmission of the default IAB DU on the second resource.

(2) Optionally, when the first resource is configured and/or indicated as a DL resource (corresponding to the above-mentioned solution 3), or the first resource is configured and/or indicated as a flexible resource (corresponding to the above-mentioned solution 5) and the first resource is defaulted In the case of DL resources:

1) The scheduling of IAB DU can meet at least one of the following:

In the case that the UL of the IAB MT and the UL of the IAB DU can be transmitted at the same time by default, the IAB DU is UL transmission on the second resource;

In the case that the UL of the IAB MT and the DL of the IAB DU can be transmitted at the same time by default, the IAB DU is transmitted as DL on the second resource;

In the case of unscheduled transmission on the first resource of the default IAB MT, the IAB DU is transmitted on the second resource.

And/or, 2) The scheduling of IAB MT can meet at least one of the following:

The reception of IAB MT is not scheduled on the first resource;

In the case that the default IAB DU is UL transmission or DL transmission on the second resource, the IAB MT is scheduled.

Understandably, since the scheduling in (2) above guarantees DU transmission priority, the IAB DU/MT scheduling in (2) above is the scheduling/transmission performed on the premise that the IAB DU is prioritized. For IAB DU transmission, it can be IAB DU reception, that is, IAB DU schedules sub-IAB nodes to send, that is, UL transmission; it can also be IAB DU transmission, that is, IAB DU instructs sub-IAB nodes to receive, that is, DL transmission.

(3) Optionally, when the first resource is configured and/or indicated as UL resources (corresponding to the above scheme 4), or the first resource is configured and/or indicated as flexible resources (corresponding to the above scheme 5) and the first resource is defaulted In the case of UL resources:

In the case that the default IAB DU is UL transmission or DL transmission on the second resource, the IAB MT is scheduled.

Understandably, since the scheduling in (4) above guarantees DU transmission first, the IAB DU/MT scheduling in (4) above is the scheduling/transmission performed on the premise that the IAB DU is prioritized. For IAB DU transmission, it can be IAB DU reception, that is, IAB DU schedules sub-IAB nodes to send, that is, UL transmission; it can also be IAB DU transmission, that is, IAB DU instructs sub-IAB nodes to receive, that is, DL transmission.

In the embodiment of the present application, the CU of the donor IAB node and/or the parent IAB node may send the preferred time domain resource configuration such as time division duplex (TDD) configuration to the IAB MT/DU.

Further, the IAB MT can receive the preferred time domain resource configuration through at least one of the following: signaling in the F1-AP, protocol data unit (Protocol Data Unit, PDU) of the backhaul access protocol (Backhaul adaptation protocol, BAP) ), RRC information and DCI.

Optionally, the IAB DU can receive preferred time-domain resource configurations from the parent IAB node and/or the donor IAB node. Further, the IAB DU can receive the preferred time-domain resource configuration through at least one of the following: signaling in the F1-AP, BAP PDU, RRC information and DCI. In this case, the parent IAB node can also configure the resource direction of the IAB DU.

It should be pointed out that the above-mentioned DCI may be a new DCI format, a new Radio Network Tempory Identity (RNTI), a new search space and/or a new control resource set CORESET, etc. The aforementioned DCI is, for example, DU-SFI.

In the embodiment of the present application, the scheduling signaling received by the IAB node includes: the scheduling signaling of the IAB MT. Wherein, the scheduling signaling of the IAB MT can be determined by the parent IAB node according to the content reported by the IAB node and/or the actual scheduling of the IAB DU. When scheduling IAB MT, although the IAB node will report the resources preferred by the IAB DU, the parent IAB node may refer to it, but in the specific scheduling, if there is a conflict, it is still hoped that the IAB DU will avoid this resource, so the IAB DU needs to Know the schedule of IAB MT.

Optionally, the scheduling signaling of the IAB MT can satisfy at least one of the following:

1) When the transmission time of the scheduling signaling of the IAB MT is M time units earlier than the transmission time of the IAB DU, the scheduling signaling of the IAB MT is effective signaling.

4) The effective time of IAB MT scheduling corresponds to the application time of the multiplexing mode of IAB MT and IAB DU. Among them, the multiplexing mode of IAB MT and IAB DU can be a multiplexing mode of semi-static/dynamic configuration.

In the embodiment of this application, the four multiplexing methods of simultaneous transmission/same reception/one transmission and one reception of IAB MT and IAB DU may not be applied to the time domain resources where IAB DU is configured as a flexible symbol, or whether to apply it according to the instruction on the IAB node.

Optionally, the IAB node may determine that the multiplexing mode of the IAB MT and the IAB DU is not applied to the configuration of the IAB DU and/or resources indicated as flexible resources. And/or, the IAB node can determine whether the multiplexing mode of the IAB MT and the IAB DU is applied to or not applied to the configuration of the IAB DU and/or resources indicated as flexible resources according to the indication of the parent IAB node and/or the donor IAB node. For example, the parent IAB node can indicate through F1-AP/high-level configuration/DCI that the multiplexing mode of simultaneous sending/receiving should not be applied or applied to the configuration of IAB DU and/or resources indicated as flexible resources. For example, Xbit(s) indication information is used to indicate whether the corresponding multiplexing method is applied to the configuration of the IAB DU and/or the resources indicated as flexible symbols.

In the embodiment of this application, the multiplexing mode of IAB MT and IAB DU can be configured semi-statically/dynamically. When the multiplexing method of IAB MT and IAB DU is applied to the IAB node, there is no priority relationship between the IAB MT and IAB DU, and the transmission behavior of the IAB node determined according to the multiplexing method can satisfy at least one of the following:

1) The first resource is configured and/or indicated as a DL resource (corresponding to the above scheme three), or the first resource is configured and/or indicated as a flexible resource (corresponding to the above scheme five) and the first resource is a DL resource by default, and When the default IAB DU is DL transmission, the transmission behavior of the IAB node includes MT reception and DU transmission;

Optionally, in this embodiment, the CU configuration/parent IAB node can be used to indicate whether the multiplexing mode of IAB MT and IAB DU is applied to the IAB node, that is to say, whether to enable the above 1) to 4) rules about transmission behavior. Specifically, the IAB node may receive first configuration information from the donor IAB node, and the first configuration information indicates that the multiplexing mode of the IAB MT and the IAB DU is to be applied to or not to be applied to the IAB node. And/or, the IAB node can receive indication information from the parent IAB node, and the indication information indicates that the multiplexing mode of the IAB MT and the IAB DU should be applied to or not applied to the IAB node.

Optionally, in this embodiment of the present application, the IAB node may also receive second configuration information from the donor IAB node, and the second configuration information is used to instruct the IAB node to determine whether the IAB MT priority or the IAB DU priority is determined according to a preset method. That is to say, the CU of the donor IAB node can configure the IAB node to judge whether IAB MT or IAB DU is prioritized according to the preset method. Among them, when there is an IAB node multiplexing restriction, the IAB DU can be limited to downlink transmission.

Optionally, the above-mentioned judging whether IAB MT priority or IAB DU priority according to the preset method may include at least one of the following:

1) According to the service load difference between the child link (child link) and the parent link (parent link) of the IAB node, determine whether the IAB MT priority or the IAB DU priority is given.

For example, if the service load/delay on the child link of the IAB node is higher than the service load/delay on the parent link of the IAB node, it can be determined that IAB DU has priority over IAB MT to use resources; conversely, IAB and MT have priority over IAB DU Use resources.

2) According to the congestion state of the child link of the IAB node and the parent link, it is determined whether the IAB MT has priority or the IAB DU has priority.

For example, if there is congestion on the child link of the IAB node but not on the parent link of the IAB node, IAB DU will use resources first, otherwise, IAB MT will use resources first.

3) According to the logical channel priority of the child link of the IAB node and the parent link, it is determined whether the IAB MT has priority or the IAB DU has priority.

For example, if the priority of the data to be transmitted on the child link of the IAB node is higher than the priority of the data to be transmitted on the parent link of the IAB node, then IAB DU will use resources first, otherwise, IAB MT will use resources first.

Optionally, the CU may be configured to use or not use one or more of the above methods 1) to 3).

Optionally, the IAB node may request the CU to configure one or more of the above methods 1) to 3). Specifically, the IAB node sends a request message to the donor IAB node, and the request message is used to request the donor IAB node to configure a preset method, and the preset method is used to determine whether IAB MT priority or IAB DU priority.

Optionally, when the reporting time of the IAB node is periodic, there may be a preset relationship between the reported content and the indication information of the reported content. The preset relationship may be determined according to preconfigured/configured/indicated parameters. For example, a code point/message indicates that the time domain resource allocation has not changed. In addition, when reporting periodically, it can also be triggered corresponding to the change of resource direction. For example: if the direction of the symbol changes, wait until the position of the periodic reporting opportunity occasion and then report. If there is no symbol direction change, a preset value information is reported periodically at the position.

2) It is related to the reporting trigger time.
