Detailed Description

The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the application, fall within the scope of protection of the application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. 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 otherwise described herein, and that the "first" and "second" distinguishing between objects generally are not limited in number to the extent that the first object may, for example, be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/" generally means a relationship in which the associated object is an "or" before and after.

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

Referring to fig. 1, fig. 1 is a schematic diagram of an IAB system to which an embodiment of the present application is applicable. In an IAB system, one IAB node includes an MT function part and a DU function part. By means of MT, an IAB node can find one or more parent IAB nodes (or upstream IAB nodes) and establish a wireless connection with the DUs of the parent IAB nodes, which is called backhaul link. After an IAB node establishes a complete backhaul link, the IAB node may turn on its DU function, where the DU may provide cell services, i.e. the DU may provide access services for User Equipment (UE). A self-backhaul loop comprises one or more donor IAB nodes (alternatively referred to as IAB donor) having a wired transmission network directly connected thereto. It should be noted that, in fig. 1, an example with one parent IAB node and one donor IAB node is shown, but the embodiment of the present application is not limited thereto.

Fig. 2 is a schematic diagram of a control Unit-Distributed Unit (CU-DU) of an IAB system according to an embodiment of the present application. In a self-backhauling loop, all IAB node DUs are connected to a CU node and configured by the CU node through the F1 application (F1-AP) protocol. The CU configures the MT through a radio resource control (Radio Resource Control, RRC) protocol. The Donor IAB node has no MT functional part.

In the embodiment of the present application, duplex (duplex) modes between the DU and the MT of the IAB node are classified into Half duplex (Half duplex) and Full duplex (Full duplex) modes. In the case of Full duplex, DU/MT can be transmitted and received simultaneously.

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

Optionally, the mode of the transmitting and receiving operation of the DU and the MT in the multiplexing mode of frequency division multiplexing (Frequency Domain Multiplexing, FDM) or space division multiplexing (Space Domain Multiplexing, SDM) of the IAB node includes, but is not limited to, at least one duplex mode of:

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

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

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

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

It should be noted that in the embodiment of the present application, DU TX and DU DL may be common, MT TX and MT UL may be common, DU RX and DU UL may be common, and MT RX and MT DL may be common.

It can be appreciated that in the embodiment of the present application, three multiplexing modes, TDM, SDM and FDM, all involve coordinated scheduling among hops. The three multiplexing modes are described as follows:

1) Time Division Multiplexing (TDM) refers to one IAB node operating an IAB MT and an IAB DU on different time domain resources. For example, the IAB MT receives a Physical downlink shared channel (Physical Downlink SHARED CHANNEL, PDSCH) from its parent IAB node or transmits a Physical Uplink shared channel (Physical Uplink SHARED CHANNEL, PUSCH) to its parent IAB node on a certain time domain resource; the IAB DU receives PUSCH on another time domain resource from or transmits PDSCH to its child IAB node or UE.

2) Space Division Multiplexing (SDM) refers to one IAB node operating an IAB MT and an IAB DU on the same time-frequency resource. For example, an IAB MT receives PDSCH from or transmits PUSCH to its parent IAB node, and an IAB DU receives PUSCH from or transmits PDSCH to its child IAB node or UE, transmitted on the same time-frequency domain resources.

3) Frequency Division Multiplexing (FDM) refers to one IAB node operating an IAB MT and an IAB DU simultaneously on different frequency resources. For example, an IAB MT receives PDSCH from or transmits PUSCH to its parent IAB node, and an IAB DU receives PUSCH from or transmits PDSCH to its child IAB node or UE, transmitted on the same time domain resources.

In the embodiment of the application, the related Full Duplex (Full Duplex) scene comprises: DU-TX & MT-RX and DU-RX & MT-TX. For example, full duplex may refer to one IAB node simultaneously receiving PDSCH from its parent and PDSCH to its child IAB nodes or UEs, or one IAB node simultaneously transmitting PUSCH to its parent and receiving PUSCH from its child IAB nodes or UEs on the same time-frequency resources.

Alternatively, for resource configuration of IAB DUs, a Donor node CU may configure the time domain resources of the DUs through F1-AP (or F1-C) signaling, such as gNB-DU resource configuration. Wherein, the type of transmission of the symbol (symbol) (or the transmission direction of the symbol) in each time slot is configured, and the symbol type (or the symbol direction) includes DL symbol, UL symbol, and flexible (flexible) symbol. The Available case of configuring each type of symbol of the DU includes a hard (hard)/soft (soft)/Not Available (Not Available) type configuration. The availability is in configuration units of symbol types.

In particular, the method comprises the steps of,

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

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

If DL/UL/flexible symbol is configured as Not Available (NA), the IAB DU is Not transmitted or received on the symbol.

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

Optionally, in the embodiment of the present application, the resource schemes for the IAB MT and the IAB DU may include at least the following 5 kinds:

Scheme one: the resource configuration and/or indication of the IAB MT is flexible (flexible) resource, and the resource configuration and/or indication of the IAB DU is DL resource;

scheme II: the resource configuration and/or indication of the IAB MT is flexible resource, and the resource configuration and/or indication of the IAB DU is UL resource;

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

scheme IV: the resource configuration and/or indication of the IAB MT is UL resource, and the resource configuration and/or indication of the IAB DU is flexible resource;

scheme five: 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 noted that in the above-mentioned first to fifth aspects, the resources of the IAB MT correspond to the resources of the IAB DU, and the corresponding may be understood as the same time domain resources, but the frequency domain resources are not limited thereto. The resources of the IAB MT may include, but are not limited to, symbol, slot, frame, etc. The resources of the IAB DU may include, but are not limited to, symbol, slot, frame, etc.

Under scheme one, scheme two and scheme five, the transmission direction of the IAB MT/DU may be determined according to at least one of: priority relation of IAB MT/DU, multiplexing capability of IAB node, signaling indication, transmission direction of IAB DU. While under schemes three, four and five, the transmission direction of the IAB MT/DU may be determined according to at least one of: priority relation of IAB MT/DU, multiplexing capability of IAB node, signaling indication, transmission direction of IAB MT.

In the embodiment of the application, different transmission behaviors can be adopted for different signals/channels. For example, for UL transmission, in case of collision, transmission of only the collided symbols may be canceled for the Sounding reference signal (Sounding REFERENCE SIGNAL, SRS), and SRS on the remaining symbols are transmitted; for transmission of Physical uplink control channel (Physical Uplink Control Channel, PUCCH)/PUSCH/Random access channel (Physical Random ACCESS CHANNEL, PRACH), if a part of symbols collide, the transmission of the entire PUCCH/PUSCH/PRACH may be canceled. For DL transmission, for DL Positioning reference signal (Positioning REFERENCE SIGNAL, PRS) transmission, if the higher layer schedule is received in flexible symbol, it can be received; if the physical downlink control channel (Physical Downlink Control Channel, PDCCH)/PDSCH/channel state Information reference signal (CHANNEL STATE Information-REFERENCE SIGNAL, CSI-RS) is received on the flexible symbol, it may not be received.

It should be noted that, in the embodiment of the present application, the MT of the IAB node may be abbreviated as an IAB MT, and the DU of the IAB node may be abbreviated as an IAB DU.

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

Referring to fig. 3, fig. 3 is a flowchart of a resource processing method provided in an embodiment of the present application, where the method is performed by an IAB node, and as shown in fig. 3, the method includes the following steps:

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

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

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

Step 32: and the IAB node determines whether the MT of the IAB node has scheduling on the first resource according to the scheduling signaling.

Optionally, the first resource is configured by the IAB MT and/or is indicated as a UL resource (corresponding to scheme four above), a DL resource (corresponding to scheme three above), or a flexible resource (corresponding to scheme five above). The first resource corresponds to a second resource, which is a configuration of the IAB DU and/or a resource indicated as a flexible resource. The correspondence of the first resource with the second resource can be understood as: the first resource is the same time domain resource as the second resource such as symbol. The frequency domain resources of the first resource and the second resource are not limited, and may be the same or different.

Alternatively, the first resource includes, but is not limited to symbol, slot, frame, microseconds, milliseconds, seconds, etc., and the second resource includes, but is not limited to symbol, slot, frame, microseconds, milliseconds, seconds, etc., without limitation of the first and second resources.

According to the resource processing method provided by the embodiment of the application, the IAB node can receive the scheduling signaling from the parent IAB node and determine whether the MT of the IAB node has scheduling on the first resource according to the scheduling signaling; the first resource is configured by the MT and/or indicated as a UL resource, a DL resource or a flexible resource; the first resource corresponds to a second resource, and the second resource is the configuration of the DU of the IAB node and/or the resource indicated as flexible resource. Therefore, under the condition that the corresponding resources of the MT and/or the DU of the IAB node are configured as flexible resources, the scheduling transmission of the MT and/or the DU can be clarified, so that the understanding of the MT and the DU is consistent, and the efficiency of the system transmission is ensured. Furthermore, the IAB MT and the IAB DU can be transmitted on flexible resources at the same time, so that the resource utilization rate is improved.

In one embodiment, under the third scheme, that is, at a certain time, the resource of the IAB MT is a DL resource, and the resource of the IAB DU is a flexible resource. The IAB node may determine whether the IAB MT has scheduling on a corresponding DL resource according to the DCI indication acquired in advance, where the corresponding DL resource is a resource that is the same time domain resource as the Flexible resource of the IAB DU. Or the IAB node may determine whether the IAB MT has scheduling on the corresponding DL resource according to transmission/reception of the configuration acquired in advance. The above configured transmission/reception, or DCI-indicated scheduling, may refer to reception of Synchronization signal block (Synchronization SIGNAL AND PBCH block, SSB)/type 0search space (type 0search space)/PDCCH/PDSCH/CSI-RS/DL PRS. If the IAB MT is not configured to detect DCI format 2-0, at least the reception of SSB may be determined for the configured transmission/reception. Other higher layer configuration transmissions and receptions may be changed by DCI, but it may be specified that the transmission and reception of a certain higher layer configuration cannot be changed by DCI.

In one embodiment, under the third or fourth aspect, for a certain time point, the Time Division Duplex (TDD) direction of the IAB MT is DL/UL, and the TDD direction of the IAB DU is flexible (abbreviated as F):

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

1) The IAB DUs cannot be scheduled, whether or not the DU resource type configuration allows for the IAB DUs scheduling.

2) The IAB DU is scheduled in a conservative mode, namely the behavior/performance of IAB MT reception cannot be influenced; the parent IAB has certain aggressiveness when scheduling the IAB MT.

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

Alternatively, when the IAB DU is scheduled, it may be assumed that the IAB MT schedule exists. And, the IAB MT may assume that the IAB DU is not scheduled when scheduled; or the IAB MT may assume that the IAB DU is scheduled as UL/DL when scheduled.

Optionally, if the parent IAB node knows whether the MT has scheduling in advance, the aggressiveness of the IAB DU scheduling can be improved correspondingly. For determining whether there is scheduling, whether there is scheduling may be determined based on DCI indication acquired in advance, or whether there is scheduling may be determined based on transmission/reception (configured transmission/reception) of configuration acquired in advance, where on the premise that IAB MT is not configured to detect DCI format 2-0, at least reception of SSB may be determined, and transmission and reception of other higher layer configuration may be changed by DCI, but transmission and reception of certain higher layer configuration may not be changed by DCI from newly prescribed.

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

1) At least the DU resource type configuration allows for the scheduling of IAB DUs, the Parent IAB node cannot schedule IAB MTs.

2) When the parent IAB node schedules the IAB MT, conservative scheduling is adopted, namely the sending behavior/performance of IAB DU scheduling cannot be influenced; the IAB DU has certain scheduling aggressiveness in scheduling.

Optionally, the parent IAB node cannot determine whether there is scheduling on the flexible resource of the IAB DU, and/or the parent IAB node cannot determine that scheduling on the flexible resource of the IAB DU is UL/DL; the parent IAB node defaults to IAB DU to any UL/DL schedule.

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 schedules according to the scheduling direction of the IAB DU. For example, the IAB DU may report scheduling plan/scheduling direction/multiplexing case, etc.

Optionally, at least one of the following assumptions is satisfied when the IAB DU is scheduled:

when the IAB DU is scheduled as UL on flexible resources, MT DL & DU UL is assumed to be performed simultaneously;

When the IAB DU is scheduled as DL on a flexible resource, the MT DL & DU DL is assumed to be performed simultaneously;

when the IAB DU is scheduled on the flexible resource, the IAB MT is assumed to be unscheduled;

Which of the above assumptions are used is determined based on the multiplexing capability (duplexing capability) of the IAB.

(3) If there is no priority relation between the IAB MT and the IAB DU, the IAB MT and the IAB DU can be preset to be scheduled according to the agreed multiplexing instance (multiplexing case). For example, it is always assumed that the transmission is simultaneous or the reception is simultaneous, multiplexing case between the IAB MT and the IAB DU is determined according to the instruction of the multiplexing method (multiplexing mode) of the CU/parent, or multiplexing case between the IAB MT and the IAB DU is determined according to the expectation multiplexing mode of the IAB report.

In another embodiment, under the fourth scheme, that is, at a certain time, the resource of the IAB MT is an UL resource, and the resource of the IAB DU is a flexible resource. The IAB node may determine whether the IAB MT has scheduling on a corresponding UL resource according to the DCI indication acquired in advance, where the corresponding UL resource is a resource that is the same time domain resource as the Flexible resource of the IAB DU. Or the IAB node may determine whether the MT has scheduling on the corresponding UL resource according to transmission/reception of the configuration acquired in advance. The transmission/reception configured as described above, or the scheduling indicated by DCI, may refer to transmission of PRACH/PUCCH/PUSCH/SRS.

It should be noted that under the fifth scheme, that is, at a certain moment, the resources of the IAB MT are flexible resources, and the resources of the IAB DU are flexible resources. If the default or assumed flexible resource of the IAB MT is DL resource, the corresponding method is the same as the method in scheme three, similar to scheme three, because the resource of the IAB DU is flexible resource. If the flexible resource of the IAB MT is default or assumed to be UL resource, the resource of the IAB DU is flexible resource, so the method is similar to scheme four, and the corresponding method is the same as that in scheme four.

In the embodiment of the application, under the condition that the flexible resource of the IAB DU is converted into the UL resource or the DL resource, the IAB MT can transmit/receive/not transmit/not receive according to the scheduling signaling and/or multiplexing mode of the IAB node and the like. For the sending/receiving behavior of the IAB MT, if the scheduling behavior of the parent IAB node depends on implementation after the IAB node reports the information, the sending/receiving behavior of the IAB MT may need to be defined to avoid collision with the IAB DU.

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

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

Not receiving on the third resource;

Receiving is not performed on the overlapping resource of the third resource and the fourth resource;

Receiving on a third resource.

Wherein the first condition may include at least one of:

1) The third resource is configured and/or indicated as DL resource, or the third resource is configured and/or indicated as flexible resource and defaults to the third resource being DL resource, and the fourth resource is DL resource, and the MT is configured and/or indicated to perform DL reception on the third resource;

2) The third resource is configured and/or indicated as DL resource, or the third resource is configured and/or indicated as flexible resource and defaults to the third resource being DL resource and the fourth resource being UL resource, and the MT is configured and/or indicated for DL reception on the third resource.

Optionally, considering the duplex manner of the IAB MT and the IAB DU, the foregoing receiving on the third resource may include: when the IAB node supports simultaneous reception of the MT and transmission of the DU, or the IAB node supports simultaneous reception of the MT and reception of the DU, the IAB MT receives on the third resource. In this way, the receiving behavior of the IAB MT can be further standardized, thereby improving the resource utilization.

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

Not transmitting on the third resource;

transmitting on overlapping resources of the third resource and the fourth resource;

And transmitting on the third resource.

Wherein the second condition may include any one of:

1) The third resource is configured and/or indicated as UL resource, or the third resource is configured and/or indicated as flexible resource and defaults to the third resource being UL resource, and the fourth resource is DL resource, and the MT is configured and/or indicated to perform UL transmission on the third resource;

2) The third resource is configured and/or indicated as UL resource, or the third resource is configured and/or indicated as flexible resource and defaults to the third resource being UL resource and the fourth resource being UL resource and the MT being configured and/or indicated for UL transmission on the third resource.

Optionally, considering the duplex manner of the IAB MT and the IAB DU, the foregoing sending on the third resource may include: when the IAB node supports simultaneous transmission of the MT and reception of the DU or the IAB node supports simultaneous transmission of the MT and transmission of the DU, the IAB MT transmits on the third resource. In this way, the sending behavior of the IAB MT can be further standardized, thereby improving the resource utilization.

Note that, overlapping resources for the third resource and the fourth resource described above may refer to the same resource in the time domain. For example, the third resource occupies symbol 1-8 and the fourth resource occupies symbol 4-10, and then the same time domain resource, i.e., overlapping resource, of the third resource and the fourth resource is symbol 4-8.

For example, taking the first resource and the second resource as symbol, if the configuration of the IAB DU and/or some/all of indicated flexible symbols are converted into DL symbol, where the IAB MT may know which flexible symbols of the IAB DU have their directions changed and belong to an internal implementation of the IAB node, then:

1) If the configuration and/or the indicated symbol of the IAB MT is DL symbol (corresponding to the third scheme), or if the configuration and/or the indicated symbol of the IAB MT is flexible symbol (corresponding to the fifth scheme) and is default to DL symbol, if the higher layer configuration/DCI indicates that the IAB MT performs 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 half-duplex constraint; or the IAB MT receives on the corresponding symbol. Wherein, when the IAB node supports MT reception and DU transmission to run simultaneously, the IAB MT is supported to receive on the corresponding symbol.

2) If the configuration and/or the indicated symbol of the IAB MT is UL symbol (corresponding to scheme four above), or if the configuration and/or the indicated symbol of the IAB MT is flexible symbol (corresponding to scheme five above) and is default to UL symbol, if the higher layer configuration/DCI indicates that the IAB MT performs UL transmission/transmission on the corresponding symbol, the IAB MT does not transmit the corresponding transmission; or the IAB MT does not send on the corresponding overlapped symbol, which is a new behavior equivalent to the operation of not enabling the IAB DU to be influenced; or the IAB MT transmits on the corresponding symbol. When the IAB node supports MT transmission and DU transmission to run simultaneously, the IAB node supports the MT to transmit on the corresponding symbol. For example, if the SRS partial symbol falls on a symbol of a flexible transition to DL of a DU, the SRS on the overlapping overlap symbol is not transmitted, but the SRS symbol of the non-overlap may be transmitted.

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

1) If the configuration and/or the indicated symbol of the IAB MT is DL symbol (corresponding to the third scheme), or if the configuration and/or the indicated symbol of the IAB MT is flexible symbol (corresponding to the fifth scheme) and is default to DL symbol, if the higher layer configuration/DCI indicates that the IAB MT performs 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 half-duplex constraint; or the IAB MT receives on the corresponding symbol. Wherein, when the IAB node supports MT reception and DU reception to run simultaneously, the IAB MT is supported to receive on the corresponding symbol.

2) If the configuration and/or the indicated symbol of the IAB MT is UL symbol (corresponding to scheme four above), or if the configuration and/or the indicated symbol of the IAB MT is flexible symbol (corresponding to scheme five above) and is default to UL symbol, if the higher layer configuration/DCI indicates that the IAB MT performs 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 symbols; or the IAB MT transmits on the corresponding symbol. When the IAB node supports MT transmission and DU transmission to run simultaneously, the IAB node supports the 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 the IAB MT is prioritized or the IAB DU is prioritized may be determined according to a preset method, or may be the default (or referred to as assumption) IAB MT priority or the default IAB DU priority.

(1) Alternatively, in the case that the first resource configuration and/or indication is DL resource (corresponding to scheme three above), or the first resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default first resource is DL resource:

1) The scheduling of the IAB DUs may satisfy at least one of:

the IAB DU is not transmitted or received on the second resource;

The IAB DU schedule is performed in the case that the default IAB MT has DL schedule. That is, the reception (performance) of the IAB MT is not affected when the IAB DU is scheduled.

And/or, 2) the scheduling of the IAB MT may satisfy:

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

It can be understood that, since the scheduling priority in (1) above ensures the scheduling of MT, the scheduling of IAB DU/MT in (1) above is the scheduling/transmission performed on the premise that IAB MT is prioritized.

(2) Alternatively, in the case that the first resource configuration and/or indication is DL resource (corresponding to scheme three above), or the first resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default first resource is DL resource:

1) The scheduling of the IAB DUs may satisfy at least one of:

in the case that the UL of the default IAB MT and the UL of the IAB DU can be transmitted simultaneously, the IAB DU is UL transmission on the second resource;

In the case that UL of the default IAB MT and DL of the IAB DU can be transmitted simultaneously, the IAB DU is DL transmission on the second resource;

in the event that the first resource of the default IAB MT does not schedule transmission, an IAB DU is transmitted on the second resource.

And/or, 2) the scheduling of the IAB MT may satisfy at least one of:

not scheduling reception of the IAB MT on the first resource;

The IAB MT is scheduled in case the default IAB DU is either a UL transmission or a DL transmission on the second resource.

It can be understood that since the scheduling in (2) above preferably guarantees the transmission of DUs, the scheduling of the IAB DUs/MTs in (2) above is the scheduling/transmission performed on the premise that the IAB DUs are preferred. For the transmission of the IAB DU, the reception of the IAB DU, that is, the transmission of the IAB DU by the IAB DU scheduling sub-IAB node, that is, the UL transmission, may be performed; it may also be an IAB DU transmission, i.e. an IAB DU indication sub-IAB node reception, i.e. DL transmission.

(3) Optionally, in the case that the first resource configuration and/or indication is UL resource (corresponding to scheme four above), or the first resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default first resource is UL resource:

1) The scheduling of the IAB DUs may satisfy at least one of:

the IAB DU is not transmitted or received on the second resource;

scheduling of the IAB DUs is performed in case that the default IAB MT has UL scheduling.

And/or, 2) the scheduling of the IAB MT may satisfy:

It can be understood that, since the schedule priority in (3) above schedules the IAB MT, the schedule of the IAB DU/MT in (3) above is the schedule/transmission performed on the premise that the IAB MT is prioritized.

(4) Optionally, in the case that the first resource configuration and/or indication is UL resource (corresponding to scheme four above), or the first resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default first resource is UL resource:

1) The scheduling of the IAB DUs may satisfy at least one of:

in the case of a non-scheduled transmission of the first resource of the default IAB MT, an IAB DU is transmitted on the second resource;

and/or, 2) the scheduling of the IAB MT satisfies at least one of:

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

It can be understood that since the scheduling in (4) above preferably guarantees the transmission of DUs, the scheduling of the IAB DUs/MTs in (4) above is the scheduling/transmission performed on the premise that the IAB DUs are preferred. For the transmission of the IAB DU, the reception of the IAB DU, that is, the transmission of the IAB DU by the IAB DU scheduling sub-IAB node, that is, the UL transmission, may be performed; it may also be an IAB DU transmission, i.e. an IAB DU indication sub-IAB node reception, i.e. DL transmission.

For example, taking the first resource and the second resource as symbol as an example, when the symbol configured and/or indicated by the IAB MT is DL symbol (corresponding to the third scheme), or the symbol configured and/or indicated by the IAB MT is flexible symbol (corresponding to the fifth scheme) and is default to DL symbol, and the symbol configured and/or indicated by the IAB DU is flexible symbol:

If the IAB MT takes precedence, then:

1) The scheduling of the IAB DUs satisfies at least one of:

the IAB DU is not transmitted/received on the Flexible symbol;

When the IAB DU is scheduled, the receiving (performance) of the IAB MT is not affected; that is, at the time of DU scheduling, it is assumed that the MT has DL scheduling.

2) The scheduling of the IAB MT satisfies:

IAB MT transmission/reception; in other words, when the parent IAB node schedules an MT, it is assumed that an IAB DU is not transmitted.

If the IAB DU is preferred, then:

1) The scheduling of the IAB MT satisfies at least one of:

The IAB MT does not receive on the corresponding symbol; or the parent IAB node does not schedule MT to receive on the corresponding symbol;

IAB MT transmission/reception; or, when the parent IAB node schedules MT, default transmission on the Flexible symbol of the IAB DU is UL or DL;

2) The scheduling of the IAB DUs satisfies at least one of:

When the IAB DU is transmitted as UL on the Flexible symbol, it is assumed that MT DL and DU UL can be performed simultaneously;

When the IAB DU is transmitted as DL on the Flexible symbol, it is assumed that MT DL and DU DL can be performed simultaneously;

When the IAB DU is transmitted on the flexible symbol, it is assumed that the IAB MT is not scheduled, i.e. the scheduling restriction of the IAB MT on the IAB DU is not considered.

For another example, when the symbol to be arranged and/or instructed by the IAB MT is UL symbol (corresponding to the fourth aspect), or the symbol to be arranged and/or instructed by the IAB MT is flexible symbol (corresponding to the fifth aspect) and is default to UL symbol, and the symbol to be arranged and/or instructed by the IAB DU is flexible symbol,

If the IAB MT takes precedence, then:

1) The scheduling of the IAB DUs satisfies at least one of:

the IAB DU is not transmitted/received on the Flexible symbol;

When the IAB DU is scheduled, the receiving (performance) of the IAB MT is not affected; that is, upon DU scheduling, it is assumed that the IAB MT has UL scheduling.

2) The scheduling of the IAB MT satisfies:

IAB MT transmission/sending; in other words, when the parent IAB node schedules an MT, it is assumed that an IAB DU is not transmitted.

If the IAB DU is preferred, then:

1) The scheduling of the IAB MT satisfies at least one of:

the IAB MT does not send on the corresponding symbol; or, the parent IAB node does not schedule MT to send on the corresponding symbol;

IAB MT transmission/sending; or, when the parent IAB node schedules MT, default transmission of Flexible symbol of the IAB DU is UL or DL;

2) The scheduling of the IAB DUs satisfies at least one of:

In the embodiment of the present application, the CU and/or parent IAB node of the donor IAB node may send a preferential time domain resource configuration, such as a Time Division Duplex (TDD) configuration, to the IAB MT/DU.

Alternatively, the IAB MT may receive a prone time domain resource configuration from the parent IAB node and/or the donor IAB node. Further, the IAB MT may receive the intended time domain resource configuration by at least one of: signaling in F1-AP, protocol data units (Protocol Data Unit, PDU) of backhaul access protocol (Backhaul adaptation protocol, BAP), RRC information, and DCI.

Alternatively, the IAB DU may receive a favored time-domain resource configuration from the parent IAB node and/or the donor IAB node. Further, the IAB DU may receive the intended time domain resource configuration by at least one of: signaling in F1-AP, BAP PDU, RRC information and DCI. In this case, the parent IAB node may also configure the resource direction of the IAB DU.

It is noted that the DCI may be a new DCI format, a new radio network temporary identity (Radio Network Tempory Identity, RNTI), a new search space and/or a new set of control resources CORESET, etc. The DCI is, for example, DU-SFI.

In the embodiment of the present application, the scheduling signaling received by the IAB node includes: and scheduling signaling of the IAB MT. The scheduling signaling of the IAB MT may be determined by the parent IAB node according to the reporting content of the IAB node and/or the actual scheduling of the IAB DU. When performing the scheduling of the IAB MT, the IAB node may report the resource that the IAB DU tends to refer to, but in the specific scheduling, if a collision occurs, it is desirable that the IAB DU avoid the resource, so that the IAB DU needs to know the scheduling of the IAB MT.

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

1) The scheduling signaling of the IAB MT is valid signaling 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.

Wherein M is an integer greater than or equal to 0. The maximum value of M, M and/or the minimum value of M may be at least one of: predefined parameters, pre-configured parameters, parameters of higher layer configuration, parameters indicated by parent IAB node. Such time units include, but are not limited to: symbols, slots, frames, microseconds, milliseconds, seconds, etc.

2) The IAB DU takes the latest received schedule of valid IAB MTs as the schedule in effect.

3) The scheduled validation time period, the maximum value of the validation time period or the minimum value of the validation time period of the IAB MT is at least one of the following: predefined parameters, pre-configured parameters, parameters of higher layer configuration, parameters indicated by parent IAB node.

4) The effective time of the schedule of the IAB MT corresponds to the application time of the multiplexing scheme of the IAB MT and the IAB DU. The multiplexing manner of the IAB MT and the IAB DU may be a semi-static/dynamic configuration multiplexing manner.

In the embodiment of the present application, four multiplexing modes of the simultaneous transmission/simultaneous reception/one-transmission of the IAB MT and the IAB DU may not be applied to a time domain resource configured as a flexible symbol by the IAB DU, or may determine whether to apply to the IAB node according to an instruction.

Optionally, the IAB node may determine that the multiplexing manner of the IAB MT and the IAB DU is not applied to the configuration of the IAB DU and/or the resources indicated as flexible resources. And/or, the IAB node may determine, according to the indication of the parent IAB node and/or the donor IAB node, a configuration and/or a resource indicated as a flexible resource in which the multiplexing manner of the IAB MT and the IAB DU is applied or not applied to the IAB DU. For example, the parent IAB node may indicate that the multiplexing mode of concurrent/co-reception is not applied or applied to the configuration of the IAB DU and/or indicate a resource that is a flexible resource through F1-AP/higher layer configuration/DCI. For example, the Xbit(s) indication information indicates whether the corresponding multiplexing method is applied to the configuration of the IAB DU and/or indicates that the multiplexing method is within the resource of the flexible symbol.

In the embodiment of the application, the multiplexing mode of the IAB MT and the IAB DU can be semi-static/dynamic configuration. When the multiplexing mode of the IAB MT and the IAB DU is applied to the IAB node, no priority relation exists between the IAB MT and the IAB DU, and the transmission behavior of the IAB node determined according to the multiplexing mode can meet at least one of the following:

1) In the case that the first resource configuration and/or indication is DL resource (corresponding to the scheme iii), or the first resource configuration and/or indication is flexible resource (corresponding to the scheme v), and the default first resource is DL resource, and the default IAB DU is DL transmission, the transmission behavior of the IAB node includes MT reception and DU transmission;

2) In the case that the first resource configuration and/or indication is DL resource (corresponding to the scheme iii), or the first resource configuration and/or indication is flexible resource (corresponding to the scheme v), and the default first resource is DL resource, and the default IAB DU is UL transmission, the transmission behavior of the IAB node includes MT reception and DU reception;

3) In the case that the first resource configuration and/or indication is UL resource (corresponding to scheme four above), or the first resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default first resource is UL resource and the default IAB DU is DL transmission, the transmission behavior of the IAB node includes MT transmission and DU transmission;

4) In the case that the first resource configuration and/or indication is UL resource (corresponding to scheme four above), or the first resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default first resource is UL resource and the default IAB DU is UL transmission, the transmission behavior of the IAB node includes MT transmission and DU reception.

Alternatively, in this embodiment, the CU configuration/parent IAB node may indicate whether the multiplexing manner of the IAB MT and the IAB DU is applied to the IAB node, that is, whether the rules 1) to 4) related to the transmission behavior are enabled. Specifically, the IAB node may receive first configuration information from the donor IAB node, where the first configuration information indicates whether the multiplexing manner of the IAB MT and the IAB DU is applied or not applied to the IAB node. And/or, the IAB node may receive indication information from the parent IAB node, where the indication information indicates whether the multiplexing mode of the IAB MT and the IAB DU is applied or not applied to the IAB node.

Optionally, in the embodiment of the present application, the IAB node may further receive second configuration information from the donor IAB node, where the second configuration information is used to instruct the IAB node to determine whether to prioritize the IAB MT or the IAB DU according to a preset method. That is, the CU of the donor IAB node may configure the IAB node to determine whether the IAB MT is preferred or the IAB DU is preferred according to a preset method. Wherein, when the IAB node multiplexing limit occurs, the IAB DU can be defined as downlink transmission.

Optionally, the determining whether the IAB MT is preferred or the IAB DU is preferred according to the preset method may include at least one of:

1) Whether the IAB MT or the IAB DU takes precedence is determined based on the traffic load difference between the child link (CHILD LINK) and the parent link (PARENT LINK) of the IAB node.

For example, if the traffic load/latency on CHILD LINK of the IAB node is higher than the traffic load/latency on PARENT LINK of the IAB node, it may be determined that the IAB DU uses resources in preference to the IAB MT; otherwise, the IAB, MT uses resources in preference to the IAB DU.

2) Whether the IAB MT is prioritized or the IAB DU is prioritized is determined according to congestion states of child links and parent links of the IAB node.

For example, if congestion occurs on CHILD LINK of the IAB node and no congestion occurs on PARENT LINK of the IAB node, the IAB DU preferentially uses the resources, otherwise, the IAB MT preferentially uses the resources.

3) Whether the IAB MT is prioritized or the IAB DU is prioritized is determined according to the logic channel priorities of the child link and the parent link of the IAB node.

For example, if the priority of the data to be transmitted on CHILD LINK of the IAB node is higher than the priority of the data to be transmitted on PARENT LINK of the IAB node, the IAB DU preferentially uses the resources, otherwise, the IAB MT preferentially uses the resources.

Alternatively, a CU may be configured with or without one or more of the methods 1) to 3) above. Specifically, the IAB node may receive third configuration information from the donor IAB node, where the third configuration information is used to instruct the IAB node to determine whether to use the preset method to prioritize the IAB MT or the IAB DU.

Alternatively, the IAB node may request configuration of one or more of the methods 1) to 3) above from the CU. Specifically, the IAB node sends request information to the donor IAB node, where the request information is used to request the donor IAB node to configure a preset method, and the preset method is used to determine whether the IAB MT is preferred or the IAB DU is preferred.

In the embodiment of the application, the parent IAB node can schedule the resource transmission of the MT according to the reporting content of the IAB node and/or the capability of the IAB node. Among other things, the capabilities of the IAB node include, but are not limited to: multiplexing capability, timing mode, power control mode, interference level, etc. The IAB node may report the time domain resource configuration to the parent IAB node/CU.

Alternatively, the IAB node may send a report content to the parent IAB node, where the report content is used for the parent IAB node to schedule the resource transmission of the MT. Therefore, by means of the reporting content of the IAB node, the parent IAB node can accurately schedule the resource transmission of the MT.

Optionally, the reporting content of the IAB node may include at least one of:

some or all of the second resources are converted into DL resources;

some or all of the second resources are converted into UL resources;

The IAB DU performs DL transmission/transmission on part or all of the second resources;

The IAB DU performs UL reception/transmission on part or all of the second resources;

IAB MT-prone time domain resource configuration/TDD configuration.

Optionally, the IAB node sends the report content to the parent IAB node by at least one of: cell specific reference signaling, uplink control information (Uplink Control Information, UCI), uplink slot format indication (Uplink Slot Format Indicator, UL-SFI), PUCCH, PUSCH, etc. The UL-SFI may be a new control information format, and an SFI table (table) is used for UL reporting; or the time domain and/or frequency domain range in which the UL-SFI takes effect is the time domain and/or frequency domain resource range in which the CU configures DU as flexible symbol.

Optionally, the reporting trigger of the IAB node satisfies at least one of:

Periodically triggering;

transmitting a transition trigger in the transmission direction of the second resource; for example, taking the second resource as a symbol, reporting may be triggered when the direction of the symbol changes.

Optionally, the reporting time of the IAB node may satisfy at least one of:

1) Periodic.

Alternatively, the period position/time length may be determined according to pre-configured/indicated parameters. The cycle positions include, but are not limited to: reporting starting position, reporting ending position, reporting time, etc.

Optionally, when the reporting time of the IAB node is periodic, a preset relationship may exist between the reporting content and the indication information of the reporting content. The preset relationship may be determined from the parameters of the preset/configuration/indication. For example, one code point/information indicates that the time domain resource configuration is unchanged. In addition, when periodically reporting, the change trigger can also occur corresponding to the direction of the resource. For example: if the symbol direction is changed, waiting until the position of the periodical reporting timer occalasion is reported again. If the sign direction is not changed, a preset value information is reported at the periodic position.

2) Is related to the reporting trigger time.

Optionally, when the reporting time is related to the reporting trigger time, N time units may be spaced between the reporting time and the reporting trigger time; n is an integer greater than or equal to 0. The time units include, but are not limited to: symbols, slots, frames, microseconds, milliseconds, seconds, etc. N may be at least one of: predefined parameters, pre-configured parameters, parameters of higher layer configuration, parameters indicated by parent IAB node.

It should be noted that the N time units may be a preparation time for reporting content, and if triggered by PUSCH reporting, may be a preparation time for PUSCH.

3) The reporting time is at least one of the following: predefined parameters, pre-configured parameters, parameters of higher layer configuration, parameters indicated by parent IAB node.

For example, the higher layer configures/instructs to employ event-triggered reporting for a certain period of time and periodic reporting for a certain period of time.

Optionally, the parent IAB node may schedule the resource transmission of the MT according to the reporting content of the IAB node. When the reporting content of the IAB node includes that part or all of the second resources are converted into DL resources, the scheduling signaling received by the IAB node may satisfy at least one of the following:

1) In the case that the first resource configuration and/or indication is DL resource (corresponding to scheme three above), or the first resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default first resource is DL resource, not scheduling reception of the IAB MT on the fifth resource; that is, the parent IAB node does not schedule reception of the IAB MT on the fifth resource;

2) Scheduling the sending of the IAB MT on a fifth resource under the condition that the first resource configuration and/or indication is UL resource (corresponding to the scheme IV) or the first resource configuration and/or indication is flexible resource (corresponding to the scheme V) and the default first resource is UL resource; that is, the parent IAB node may schedule the sending of the IAB MT on the fifth resource.

The fifth resource is a resource corresponding to a resource converted into a DL resource in the second resource, and the correspondence is understood to be the same time domain resource, but the frequency domain resource is not limited and may be the same or different.

Optionally, when the reporting content of the IAB node includes that part or all of the second resources are converted into UL resources, the scheduling signaling received by the IAB node may satisfy at least one of the following:

1) Scheduling reception of the IAB MT on a sixth resource if the first resource configuration and/or indication is DL resource (corresponding to scheme three above) or the first resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default first resource is DL resource; that is, the parent IAB node may schedule reception of the IAB MT on the sixth resource;

2) If the first resource configuration and/or indication is UL resource (corresponding to scheme four above), or the first resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default first resource is UL resource, sending of the IAB MT is not scheduled on the sixth resource; that is, the parent IAB node does not schedule the sending of the IAB MT on the sixth resource.

The sixth resource is a resource corresponding to a resource converted into UL resource in the second resource, and the corresponding resource is understood to be the same time domain resource, but not limited to the frequency domain resource.
