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 availability of symbols for each type of configuration DU includes a hard (hard)/soft (soft)/Not Available (Not Available) type of 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 flexible resources and the resource configuration and/or indication of the IAB DU is flexible resources.

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.

Alternatively, in the embodiment of the present application, for the transmission of the IAB DU, it may be an IAB DU reception, that is, an IAB DU scheduling sub-IAB node sending, that is, UL transmission; it may also be an IAB DU transmission, i.e. an IAB DU indication sub-IAB node reception, i.e. DL transmission.

Alternatively, "default" in embodiments of the present application may be understood as a hypothesis.

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

Referring to fig. 3, fig. 3 is a flowchart of a transmission processing method according to an embodiment of the present application, where the method is performed by an IAB node. As shown in fig. 3, the method comprises the steps of:

step 31: the MT of the IAB node performs a first operation on a first resource and/or the DU of the IAB node performs a second operation on a second resource.

Optionally, the first operation may include at least one of: transmitting, receiving, not transmitting, not receiving. The second operation may include at least one of: transmitting, receiving, not transmitting, not receiving.

Optionally, the first resource is a configuration of the IAB MT and/or a resource indicated as a flexible resource. The first resource corresponds to a second resource, which is a configuration of the IAB DU and/or a resource indicated as UL resource (corresponding to scheme two above), DL resource (corresponding to scheme one above) or flexible resource (corresponding to scheme five above). 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 may include, but is not limited to symbol, slot, frame, microseconds, milliseconds, seconds, etc., and the second resource may include, but is not limited to symbol, slot, frame, microseconds, milliseconds, seconds, etc., without limitation of the first and second resources.

According to the transmission processing method, the MT of the IAB node can execute a first operation on a first resource, and/or the DU of the IAB node can execute a second operation on a second resource; the first resource is the configuration of the MT and/or the resource indicated as flexible resource; the first resource corresponds to a second resource, which is a configuration of the DU and/or a resource indicated as UL resource, DL resource or 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 transmission behavior of the MT and/or the DU can be clarified, so that the IAB MT and the IAB DU can be transmitted on the flexible resources simultaneously, and the resource utilization rate is improved.

In one embodiment, under the above scheme, that is, at a certain time, the resource of the IAB MT is a flexible resource, and the resource of the IAB DU is a DL resource. The IAB node may determine, according to the DCI indication acquired in advance, whether the IAB MT has scheduling on the corresponding flexible resource. Or the IAB node may determine whether the IAB MT has scheduling on the corresponding flexible resource according to the transmission/reception of the configuration acquired in advance. Alternatively, the transmission/reception configured as above, or the scheduling indicated by DCI, may refer to reception of a Synchronization SIGNAL AND PBCH block (SSB)/type 0search space (type 0search space)/PDCCH/PDSCH/CSI-RS/DL PRS, or transmission of PRACH/PUCCH/PUSCH/SRS. 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 transmissions and receptions of a certain higher layer configuration cannot be changed by DCI. The corresponding flexible resource is the same time domain resource as the DL resource of the IAB DU.

In another embodiment, under the first or second embodiment, for a certain time point, the Time Division Duplex (TDD) direction of the IAB MT is flexible (may be abbreviated as F), and the TDD direction of the IAB DU is DL/UL:

(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) If the DU resource type configuration allows the IAB DU to schedule, the IAB DU is scheduled in a conservative mode, and the parent IAB has certain scheduling aggressiveness when scheduling the IAB MT.

Optionally, the IAB DU cannot determine whether there is scheduling on the flexible resource of the IAB MT, and/or the IAB DU cannot determine that the scheduling on the flexible resource of the IAB MT is UL/DL; the IAB DU default parent IAB may make any UL/DL schedule.

Optionally, if the IAB DU can determine whether the flexible resource of the IAB MT is scheduled, and/or determine that the scheduling on the flexible resource of the IAB MT is UL/DL, the IAB DU schedules according to the scheduling direction of the IAB MT.

Further, for determining whether there is a schedule: the IAB DU can determine whether scheduling exists or not according to DCI indication acquired in advance; or the IAB DU may determine whether there is scheduling according to the transmission/reception (configured transmission/reception) of the configuration acquired in advance, where on the premise that the IAB MT is not configured to detect the DCI format 2-0, at least the reception of the SSB may be determined, and the transmission/reception of other higher layer configurations may be changed by the DCI, but the transmission/reception of a certain higher layer configuration may be newly specified and may not be changed by the DCI.

Further, for determining that scheduling on flexible resources of the IAB MT is UL/DL: the IAB DU can determine the TDD direction according to the DCI indication acquired in advance; or the IAB DU determines the TDD direction according to the DCI format 2-0 indication acquired in advance; or the IAB DU may determine the TDD direction according to the transmission/reception of the configuration acquired in advance, where on the premise that the IAB MT is not configured to detect the DCI format 2-0, at least the reception of the SSB may be determined, and the transmission/reception of other higher layer configurations may be changed by the DCI, but the transmission/reception of a certain higher layer configuration may be newly specified and may not be changed by the DCI.

Optionally, the aggressiveness of parent IAB node scheduling at least satisfies at least one of the following assumptions:

when the scheduling of the parent IAB node on the flexible resource of the IAB MT is UL, the MT UL & DU DL is supposed to be performed simultaneously;

When scheduling of the parent IAB node on flexible resources of the IAB MT is DL, the MT DL & DU DL is assumed to be performed simultaneously;

when the parent IAB node schedules on the flexible resource of the IAB MT, the IAB DU is assumed to be unscheduled;

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

(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 scheduling has a certain aggressiveness.

Optionally, for the aggressiveness of IAB DU scheduling: the IAB DU scheduling can be carried out by assuming that the parent IAB node has no scheduling; or the IAB DU scheduling may assume that the partial IAB node schedules UL/DL.

Alternatively, when the parent IAB node schedules an IAB MT, it may be assumed that there is a DU schedule. And, the IAB DU scheduling can assume that the parent IAB node has no scheduling; or the IAB DU schedule may assume that the parent IAB node is scheduled UL/DL.

Optionally, if the parent IAB node knows whether the DU is scheduled or not in advance, the aggressiveness of the scheduling of the parent IAB node may be correspondingly improved, for example, a DU reporting scheduling plan (scheduling plan) and the like.

(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 second scheme, that is, at a certain time, the resource of the IAB MT is a flexible resource, and the resource of the IAB DU is an UL resource. The IAB node may determine, according to the DCI indication acquired in advance, whether the IAB MT has scheduling on the corresponding flexible resource. Or the IAB node may determine whether the MT has scheduling on the corresponding flexible resource according to the transmission/reception of the configuration acquired in advance. The transmission/reception configured as described above, or the scheduling indicated by DCI, may refer to the reception of SSB/type 0search space/PDCCH/PDSCH/CSI-RS/DL PRS, or the transmission of PRACH/PUCCH/PUSCH/SRS. The corresponding flexible resource is the same time domain resource as the UL resource of the IAB DU.

In another embodiment, under the above scheme, that is, at a certain time, the resource of the IAB MT is a flexible resource, and the resource of the IAB DU is a DL resource. The IAB node may determine a Time Division Duplex (TDD) direction of the IAB MT on a corresponding flexible resource according to the DCI indication acquired in advance. Or the IAB node determines the TDD direction of the IAB MT on the corresponding Flexible resource according to the DCI format 2-0 instruction acquired in advance. Or the IAB node may determine the TDD direction of the IAB MT on the corresponding Flexible resource according to the transmission/reception of the configuration acquired in advance. The corresponding flexible resource is the same time domain resource as the DL resource of the IAB DU.

In another embodiment, under the second scheme, that is, at a certain time, the resource of the IAB MT is a flexible resource, and the resource of the IAB DU is an UL resource. The IAB node can determine the TDD direction of the IAB MT on the corresponding flexible resource according to the DCI instruction acquired in advance. Or the IAB node can determine the TDD direction of the IAB MT on the corresponding Flexible resource according to the DCI format 2-0 instruction acquired in advance. Or the IAB node may determine the TDD direction of the IAB MT on the corresponding Flexible resource according to the transmission/reception of the configuration acquired in advance. The corresponding flexible resource is the same time domain resource as the UL resource of the IAB DU.

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 DU is DL resource, the corresponding method is similar to scheme one and scheme one method is the same as the resource of the IAB MT is flexible resource. If the flexible resource of the IAB DU is the UL resource by default or assumed, the resource of the IAB MT is the flexible resource, so the method is similar to the scheme two, and the corresponding method is the same as the scheme two.

In the embodiment of the present application, based on the scheduled and/or configured transmission of the IAB MT on the first resource, the IAB MT may have different transmission behaviors. Optionally, when the second resource configuration and/or indication is DL resource (corresponding to scheme one above), or the second resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default second resource is DL resource, the performing the first operation on the first resource may include at least one of:

when the default first resource is an UL or DL resource and UL transmissions of the IAB MT are scheduled and/or configured on the first resource, the IAB MT does not transmit on the first resource;

When the default first resource is a UL or DL resource and DL transmissions of the IAB MT are scheduled and/or configured on the first resource, the IAB MT receives on the first resource;

when UL transmissions of the IAB MT are not scheduled and/or configured on the first resource and the default first resource is DL resource, the IAB MT receives on the first resource;

When no UL transmissions of the IAB MT are scheduled and/or configured on the first resource and the default first resource is a flexible resource, the IAB MT does not transmit and receive on the first resource;

When the first resource is scheduled to be a flexible resource, the IAB MT does not send and receive on the first resource;

And the IAB MT executes the first operation on the first resource according to multiplexing capability of the IAB node and/or preset rules. For example, the preset rule may include at least one of: 1) In the case that the default MT UL and DU DL are performed simultaneously, the IAB MT transmits for the UL, or the parent IAB node schedules the IAB MT to transmit for the UL on flexible resources; 2) Under the condition that default MT DL and DU DL are performed simultaneously, IAB MT is DL reception, or parent IAB node schedules IAB MT to be DL reception on flexible resources; 3) In case of no transmission of default IAB DUs, the parent IAB node schedules the IAB MT on flexible resources, i.e. independent of the IAB DU transmission.

Optionally, when the second resource is configured as an UL resource (corresponding to scheme two above), or the second resource is configured and/or indicated as a flexible resource (corresponding to scheme five above) and the default second resource is an UL resource, the performing the first operation on the first resource may include at least one of:

When the default first resource is a UL or DL resource and DL transmissions of the IAB MT are scheduled and/or configured on the first resource, the IAB MT does not receive on the first resource;

when the default first resource is an UL or DL resource and UL transmissions of the IAB MT are scheduled and/or configured on the first resource, the IAB MT transmits on the first resource;

when DL transmissions of the IAB MT are not scheduled and/or configured on the first resource and the default first resource is UL resource, the IAB MT transmits on the first resource;

when DL transmissions of the IAB MT are not scheduled and/or configured on the first resource and the default first resource is a flexible resource, the IAB MT does not transmit and receive on the first resource;

And the IAB MT executes the first operation on the first resource according to multiplexing capability of the IAB node and/or preset rules. For example, the preset rule may include at least one of: 1) In the case that the default MT UL and DU UL are performed simultaneously, the IAB MT transmits for the UL, or the parent IAB node schedules the IAB MT to transmit for the UL on flexible resources; 2) In the case that the default MT DL and DU UL are performed simultaneously, the IAB MT is DL reception, or the parent IAB node schedules the IAB MT to be DL reception on flexible resources; 3) In case of no transmission of default IAB DUs, the parent IAB node schedules the IAB MT on flexible resources, i.e. independent of the IAB DU transmission.

Alternatively, the IAB MT may perform the first operation on the first resource if at least one of:

The transmissions of the IAB node are determined according to the priorities of the DU transmissions and the MT scheduling, or the transmissions of the IAB node are determined according to the priority rules of the DU transmissions and the MT scheduling. For example, the priority rule for the transmission of the DU and the scheduling of the MT may be either the transmission priority of the DU or the scheduling priority of the MT.

In the case where there is a transmission of the default IAB DU, the IAB MT is scheduled by the parent IAB node.

Alternatively, when the IAB DU is not transmitted, the first resource of the IAB MT can be scheduled as UL resource, DL resource, or flexible resource by the parent IAB node.

Optionally, the performing the second operation on the second resource may include at least one of:

The IAB DU is not transmitted and received on the second resource;

The IAB DUs are transmitted and/or received on the second resources according to the schedule of the IAB MT.

Alternatively, in the embodiment of the present application, the transmission behavior of the IAB MT and the transmission behavior 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 preferred or the IAB DU is preferred may be determined according to a preset method, such as predefined, preconfigured and/or configured as IAB MT preferred or IAB DU preferred, or may be default (or referred to as hypothesized) IAB MT preferred or default IAB DU preferred.

For example, taking the first resource and the second resource as symbols, in the above scheme, namely, the CU/parent IAB node configures or indicates that a part of the IAB DU resources are DL symbols, and the parent IAB node configures or indicates that the IAB MT resources corresponding to the part of the resources are flexible symbols:

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

1) The default IAB MT resource is DL/UL, or stated another way, it is assumed that the parent IAB node schedules the IAB MT resource as UL/DL. At this time, the transmission of the IAB DU is guaranteed, the half duplex of the IAB node is guaranteed, and the interference is small.

Optionally, if the IAB MT receives the DCI schedule, or the UL transmission of the higher layer configured IAB MT is on the corresponding flexible symbol, the IAB MT does not send the information.

Optionally, if the IAB MT receives DCI scheduling, or if DL transmission of the higher layer configuration IAB MT is on the corresponding flexible symbol, the IAB MT receives information on the corresponding flexible symbol.

2) If the IAB MT does not receive the (valid) DCI indication/the IAB MT configured by the higher layer is UL scheduling, then the resource of the IAB MT is assumed to be DL or flexible. There is no distinction between higher layer signaling/physical layer signaling, and it is believed that all signaling should be complied with.

Alternatively, if the default corresponding flexible symbol is DL, the transmission behavior of the IAB MT is as described in 1) above.

Alternatively, if the default corresponding symbol is flexible, the IAB MT does not transmit or receive on the corresponding symbol.

3) If the DCI indicates that the symbol of the IAB MT is flexible, the default IAB MT does not transmit or receive the symbol. That is, in the case where at least the DU resource type configuration allows the transmission of DUs, the IAB node does not expect the parent IAB node to schedule the MT. This IAB MT does not transmit or receive on the flexible symbol, and corresponds to the function of using the flexible symbol indicated by DCI as NA in MT, and ensures transmission of DU.

4) Alternatively, the default/assumption in 1) -3) above is employed when at least one of the following is satisfied:

the transmission of the IAB node is determined according to the priority of the DU transmission and the MT scheduling, or the transmission of the IAB node is determined according to the priority rule of the DU transmission and the MT scheduling;

5) If the parent IAB node acquires the DU without transmission in advance, the parent IAB node can schedule the flexible symbol of the IAB MT to be UL/DL/flexible. The information that the DU does not transmit may be that the DU reports to the parent IAB node.

(2) If IAB MT priorities are predefined, preconfigured and/or configured, then:

1) The behavior of the IAB DU satisfies at least one of:

a) The IAB DUs are not transmitted and received on the corresponding symbol. That is, regardless of whether the DU resource type configuration allows the transmission of an IAB DU, the IAB DU is not transmitted and received on the corresponding symbol.

B) The IAB DUs are transmitted and/or received on the corresponding symbol according to the schedule of the IAB MT. That is, if the DU resource type configuration allows the DU scheduling, the IAB DU is scheduled in a conservative manner, and the parent IAB node has a certain scheduling aggressiveness when scheduling the MT.

For example, the IAB DU default parent IAB node can do any UL/DL scheduling; the IAB DU cannot determine whether the flexible symbol of the IAB MT is scheduled or not and/or the IAB DU cannot determine whether the flexible symbol of the IAB MT is scheduled to UL or DL. In this case, scheduling may only be possible if the IAB node supports full duplex, otherwise the high probability is not possible. For another example, the IAB DU can determine whether or not the flexible symbol of the IAB MT is scheduled, and/or if the flexible symbol of the IAB MT is scheduled as UL or DL, the IAB DU is transmitted according to the scheduler of the IAB MT.

2) The IAB MT determines the transmission direction of the IAB MT according to multiplexing capability of the IAB node or default rules, and at least one of the following is satisfied:

a) Under the condition that the default MT UL and DU DL are performed simultaneously, the IAB MT transmits for UL, or the parent IAB node schedules the IAB MT to transmit for UL on a flexible symbol;

b) In the case that default MT DL and DU DL are performed simultaneously, IAB MT is DL reception, or parent IAB node schedules IAB MT to be DL reception on flexible symbol;

c) In the case of default IAB DUs no transmission, the parent IAB node schedules the IAB MT on the flexible symbol, i.e. independent of the IAB DU transmission.

For example, taking the first resource and the second resource as symbols, in the second scheme, that is, the CU/parent IAB node configures or indicates that a part of resources of the IAB DU is UL symbols, and the parent IAB node configures or indicates that an IAB MT resource corresponding to the part of resources is flexible symbols:

1) The default IAB MT's resources are UL/DL.

Optionally, if the IAB MT receives DCI scheduling, or DL transmission of the higher layer configuration IAB MT is on the corresponding flexible symbol, the IAB MT does not receive the information.

Optionally, if the IAB MT receives DCI scheduling, or the UL transmission of the higher layer configured IAB MT is on the corresponding flexible symbol, the IAB MT sends information on the corresponding flexible symbol.

It should be noted that, for the default IAB MT to be DL, it is considered that the IAB MT needs to monitor the PDCCH, transmit UL information, or monitor the PDCCH to receive DL information. When the scheduling information is not received, it may be necessary to monitor the PDCCH first.

2) If the IAB MT does not receive the (valid) DCI indication/the IAB MT configured by the higher layer is DL scheduling, the resource of the IAB MT is UL or flexible.

Alternatively, if the default corresponding flexible symbol is UL, the transmission behavior of the IAB MT is as shown in 1) above.

Alternatively, if the default corresponding flexible symbol is flexible, the IAB MT does not transmit or receive on the corresponding symbol.

3) If the DCI indicates that the symbol of the IAB MT is flexible, the default IAB MT does not transmit or receive the symbol. That is, if the IAB node does not expect the parent IAB node to schedule the MT, at least the DU resource type configuration allows the transmission of the DU.

(2) If IAB MT priorities are predefined, preconfigured and/or configured, then:

1) The behavior of the IAB DU satisfies at least one of:

a) In the case that the default MT UL and DU UL are performed simultaneously, the IAB MT transmits for the UL, or the parent IAB node schedules the IAB MT to transmit for the UL on flexible resources;

b) In the case that the default MT DL and DU UL are performed simultaneously, the IAB MT is DL reception, or the parent IAB node schedules the IAB MT to be DL reception on flexible resources;

c) In case of no transmission of default IAB DUs, the parent IAB node schedules the IAB MT on flexible resources, i.e. independent of the IAB DU transmission.

In the embodiment of the application, the IAB node may receive the scheduling signaling, such as the scheduling signaling of the IAB MT, from the parent IAB node. The schedule 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 schedule of the IAB DU, etc. Further, the IAB DU may determine the transmission direction of the IAB MT according to the scheduling signaling of the IAB MT, that is, determine that the resource of the IAB MT is UL/DL/flexible.

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 time domain resources configured as flexible symbols of the IAB DU, or may determine whether to apply to the IAB node according to the indication.

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, xbit(s) indication information may be used to indicate whether the corresponding multiplexing mode is applied to configuration of the IAB DU and/or indicate a resource of 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 second resource configuration and/or indication is DL resource (corresponding to scheme one above), or the second resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default second resource is DL resource and the default IAB MT is UL transmission, the transmission behavior of the IAB node includes MT transmission and DU transmission. Alternatively, the IAB MT may be sent on part/all of the resources of the UL transmission of the higher layer configuration/DCI schedule.

2) In the case that the second resource configuration and/or indication is DL resource (corresponding to scheme one above), or the second resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default second resource is DL resource, and the default IAB MT is DL transmission, the transmission behavior of the IAB node includes MT reception and DU transmission. Alternatively, the IAB MT may receive on part/all of the resources of the DL transmission of the higher layer configuration/DCI schedule.

3) In the case that the second resource configuration and/or indication is UL resource (corresponding to scheme two above), or the second resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default second resource is UL resource and the default IAB MT is DL transmission, the transmission behavior of the IAB node includes MT reception and DU reception. Alternatively, the IAB MT may receive on part/all of the resources of the DL transmission of the higher layer configuration/DCI schedule.

4) In the case that the second resource configuration and/or indication is UL resource (corresponding to scheme two above), or the second resource configuration and/or indication is flexible resource (corresponding to scheme five above) and the default second resource is UL resource, and the default IAB MT is UL transmission, the transmission behavior of the IAB node includes MT transmission and DU reception. Alternatively, the IAB MT may be sent on part/all of the resources of the UL transmission of the higher layer configuration/DCI schedule.

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.

In addition, the IAB node may also report its expected multiplexing method, so as to determine the transmission directions of the IAB MT and the IAB DU.

In the embodiment of the present application, the IAB node may default/assume that the transmission direction of the IAB MT is related to the resource type of the DU and/or the resource direction of the DU. The resources configured/indicated as flexible resources for the MT, i.e. the first resources, may fulfil at least one of the following:

a) When the second resource is configured as a Hard resource, the IAB MT defaults to the same transmission direction on the first resource as the IAB DU.

For example, under the above scheme, that is, the second resource configuration and/or indication is DL resource, if the resource type of the IAB DU is hard, the IAB MT is DL transmission; or if the DCI indicates/high-layer signaling schedules the IAB MT to receive DL information, such as PDSCH/PDCCH/CSI-RS/DL PRS, on the corresponding resource, the IAB MT receives the information at the corresponding location.

For another example, in the second scheme, that is, the second resource configuration and/or indication is UL resource, if the resource type of the IAB DU is hard, the IAB MT is UL transmission; or if the DCI indicates/higher layer signaling schedules the IAB MT to transmit UL information, such as PUCCH/PUSCH/PRACH/SRS, on the corresponding resource, the IAB MT transmits the information at the corresponding location.

B) When the second resource is configured as a Soft resource, the IAB MT performs a third operation.

Optionally, the third operation may include at least one of:

When the IAB MT is scheduled and/or configured to transmit on the first resource, the IAB MT transmits on the first resource, i.e. considers UL transmissions. For example, if the DCI/higher layer schedules the IAB MT to transmit on the corresponding symbol, the IAB MT transmits on the corresponding symbol.

When the IAB MT is scheduled and/or configured to receive on the first resource, the IAB MT receives, i.e. considers, the DL transmission on the first resource. For example, if the DCI/higher layer schedules the IAB MT to be received on the corresponding symbol, the IAB MT is received on the corresponding symbol.

When the IAB MT is configured to transmit on the first resource and the IAB MT is scheduled to receive on some or all of the first resource, the IAB MT does not transmit on the first resource or the IAB MT transmits on some of the first resource, which may refer to SRS transmission on some of the symbols. For example, if the higher layer schedules the IAB MT to transmit on the corresponding symbol, the IAB MT detects that the DCI schedules it to receive on part/all of the symbols, the IAB MT does not transmit on the corresponding symbol, or the IAB MT transmits on part of the symbols.

When the IAB MT is configured to receive on the first resource and the IAB MT is scheduled to transmit on some or all of the first resource, no reception is performed on the first resource. For example, if the higher layer schedules the IAB MT to receive on the corresponding symbol, the IAB MT detects that the DCI schedules it to transmit on part/all of the symbols, and the IAB MT cannot receive on the corresponding symbol.

C) When the second resource is configured as an unavailable Not Available, the MT performs a transmission behavior according to a preset rule, i.e., is consistent with an existing transmission behavior, without considering the transmission behavior of the IAB DU.

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.
