Detailed Description

The technical solutions in the embodiments of the present application will be described below clearly with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived from the embodiments given herein by a person of ordinary skill in the art are intended to be within the scope of the present disclosure.

The terms first, second and the like in the description and in the claims of the present application 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 other sequences than those illustrated or otherwise described herein, and that the terms "first" and "second" are generally used herein in a generic sense to distinguish one element from another, and not necessarily from another element, such as a first element which may be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, and a character "/" generally means that the former and latter related objects are in an "or" relationship.

To facilitate understanding of the embodiments of the present application, the following is first explained.

Referring to fig. 1, fig. 1 is a schematic diagram of an IAB system to which the embodiment of the present application is applicable. In the IAB system, one IAB node includes an MT function part and a DU function part. By means of the MT, an IAB node can find a parent IAB node (or called upstream IAB node) and establish a wireless connection with the DU of the parent IAB node, which is called backhaul link. After an IAB node establishes a complete backhaul link, the IAB node may open its DU function, and the DU may provide a cell service, that is, the DU may provide an access service for a User Equipment (UE). A self-backhauling loop comprises a donor (alternatively referred to as an IAB donor) IAB node/s having a wired transport network directly connected to it. Note that, fig. 1 shows an example with one parent IAB node and one donor IAB node, but the embodiment of the present application is not limited thereto.

Fig. 2 is a schematic structural diagram of a control Unit-Distributed Unit (CU-DU) of the IAB system in the embodiment of the present application. In a self-backhauling loop, all the IAB node DUs are connected to one CU node and the DU is configured by the CU node via the F1 application (F1-AP) protocol. The CU configures the MT by using a Radio Resource Control (RRC) protocol. The Donor IAB node has no MT functionality.

In the embodiment of the present application, duplex (duplexing) modes between the DU and the MT of the IAB node are divided into Half duplex (Half duplex) and Full duplex (Full duplex) modes. In the case of Full duplex, DU/MT can transmit and receive simultaneously.

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

Optionally, the DU and the MT of the IAB node are in a Multiplexing mode of Frequency Domain Multiplexing (FDM) or Space Domain Multiplexing (SDM), and the transceiving operation modes of the DU and the MT include, but are not limited to, at least one of the following duplexing modes:

1) DU-TX & MT-TX; that is, DU is configured as Downlink (DL), MT is configured as Uplink (UL); alternatively, there is actual DL transmission for DU and actual UL transmission for MT;

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

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

Note 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 understood that, in the embodiment of the present application, the TDM, SDM and FDM all involve coordinated scheduling between hops. The three multiplexing schemes are explained as follows:

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

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

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 or transmits a PDSCH from or to its parent IAB node, and an IAB DU receives or transmits a PUSCH from or to its child IAB node or UE, which are transmitted on the same time domain resource.

In the embodiment of the present application, a Full Duplex (Full Duplex) scenario includes: DU-TX & MT-RX and DU-RX & MT-TX. For example, full duplex may refer to an IAB node simultaneously receiving a PDSCH from its parent IAB node and transmitting a PDSCH to its child IAB node or UE, or an IAB node simultaneously transmitting a PUSCH to its parent IAB node and receiving a PUSCH from its child IAB node or UE on the same time-frequency resource.

Optionally, for resource configuration of an IAB DU, the Donor node CU may configure time domain resources of the DU through F1-AP (or F1-C) signaling, such as gNB-DU resource configuration. The type of transmission (or the transmission direction) of a symbol (symbol) in each timeslot is configured, and the symbol type (or the symbol direction) includes DL symbol, UL symbol, and flexible symbol. The Available cases of symbols for each type of configuration DU include configurations of hard (hard)/soft (soft)/Not Available (Not Available) types. The available cases are in the unit of configuration of symbol type.

In particular, the method comprises the following steps of,

if DL/UL/flex symbol is configured as hard, IAB DU can be transmitted/received/transmitted or received on this symbol;

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

-if DL/UL/flex symbol is configured to Not Available (NA), then IAB DU is Not sent nor received on this symbol.

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

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

the first scheme is as follows: 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;

the third scheme is as follows: 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;

and the scheme is as follows: 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;

and a fifth scheme: 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 flexible resource.

It should be noted that in the first to fifth solutions, the resources of the IAB MT correspond to the resources of the IAB DU, and this correspondence can be understood as the same time domain resources, and the frequency domain resources are not limited. 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 the first scheme, the second scheme and the fifth scheme, the transmission direction of the IAB MT/DU can be determined according to at least one of the following items: priority relation of IAB MT/DU, multiplexing capability of IAB node, signaling indication and transmission direction of IAB DU. And under the third scheme, the fourth scheme and the fifth scheme, the transmission direction of the IAB MT/DU can be determined according to at least one of the following items: priority relation of IAB MT/DU, multiplexing capability of IAB node, signaling indication and transmission direction of IAB MT.

In the embodiment of the present application, different transmission behaviors may be taken for different signals/channels. For example, for UL transmissions, in case of collision, for Sounding Reference Signal (SRS), the transmission of only the collided symbols may be cancelled, with SRS on the remaining symbols transmitted; for transmission of a Physical Uplink Control Channel (PUCCH)/PUSCH/Random Access Channel (PRACH), if part of symbols collide, transmission of the entire PUCCH/PUSCH/PRACH may be cancelled. For DL transmission, for transmission of a DL Positioning Reference Signal (PRS), if a high layer is scheduled to receive in a flexible symbol, it can receive; if a Physical Downlink Control Channel (PDCCH)/PDSCH/Channel State Information Reference Signal (CSI-RS) is received on a flexible symbol, the Physical Downlink Control Channel (PDCCH)/PDSCH/Channel State Information Reference Signal (CSI-RS) may not be received.

Note that in the embodiment of the present application, the MT of the IAB node may be abbreviated as IAB MT, and the DU of the IAB node may be abbreviated as IAB DU.

Optionally, in this embodiment of the present application, for transmission of an IAB DU, the IAB DU may be received, that is, the IAB DU schedules a child IAB node to send, that is, UL transmission; it may also be an IAB DU send, i.e. the IAB DU indicates the child IAB node to receive, i.e. DL transmission.

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

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

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

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

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 resource configured and/or indicated as a flexible resource by the IAB MT. The first resource corresponds to a second resource, and the second resource is a resource whose configuration and/or indication of the IAB DU is UL resource (corresponding to scheme two above), DL resource (corresponding to scheme one above) or flexible resource (corresponding to scheme five above). The correspondence between the first resource and the second resource can be understood as: the first resource and the second resource are the same time domain 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, microsecond, millisecond, second, etc., and the second resource may include, but is not limited to, symbol, slot, frame, microsecond, millisecond, second, etc., without limitation thereto.

In the transmission processing method of the embodiment of the present application, an MT of an IAB node may execute a first operation on a first resource, and/or a DU of the IAB node may execute a second operation on a second resource; the first resource is a resource of the MT configured and/or indicated as a flexible resource; the first resource corresponds to a second resource, and the second resource is a resource in which the configuration and/or indication of the DU is UL resource, DL resource, or flexible resource. Therefore, the transmission behavior of the MT and/or the DU can be determined under the condition that the corresponding resources of the MT and/or the DU of the IAB node are configured into flexible resources, so that the IAB MT and the IAB DU can be simultaneously transmitted on the flexible resources, and the resource utilization rate is improved.

In one embodiment, under the above scheme, that is, at a certain time, the resources of the IAB MT are flexible resources, and the resources of the IAB DU are DL resources. The IAB node may determine whether there is scheduling on the corresponding flexible resource by the IAB MT according to the DCI indication acquired in advance. Or, the IAB node may determine whether there is scheduling on the corresponding flexible resource for the IAB MT according to the transmission/reception of the configuration acquired in advance. Optionally, the transmission/reception configured as described above or the scheduling indicated by the DCI may refer to reception of a Synchronization Signal 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, reception of at least SSB may be determined for configured transmission/reception. The transmission and reception of other higher-layer configurations may be changed by the DCI, but it may be specified that the transmission and reception of a certain higher-layer configuration cannot be changed by the DCI. Here, the corresponding flexible resource is a resource that is the same time domain resource as the DL resource of the IAB DU.

In another embodiment, in the first or second aspect, at 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 IAB MT priority is predefined, preconfigured and/or configured, at least one of the following is satisfied:

1) No matter if the DU resource type configuration allows IAB DU scheduling, the IAB DU cannot be scheduled.

2) If the DU resource type configuration allows the IAB DU scheduling, the IAB DU is scheduled in a conservative way, and the parent IAB has certain scheduling aggressiveness when the parent IAB schedules the IAB MT.

Optionally, the IAB DU may not determine whether the flexible resource of the IAB MT is scheduled, and/or the IAB DU may not determine that the scheduling on the flexible resource of the IAB MT is UL/DL; the IAB DU default parent IAB can do any UL/DL scheduling.

Optionally, if the IAB DU can determine whether the flexible resource of the IAB MT is scheduled or not, and/or determine that the scheduling on the flexible resource of the IAB MT is UL/DL, the IAB DU performs scheduling according to the scheduling direction of the IAB MT.

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

Further, for determining the scheduling on the flexible resource of the IAB MT as UL/DL: the IAB DU can determine the TDD direction according to the DCI indication obtained in advance; or, the IAB DU determines the TDD direction according to the DCI format 2-0 indication obtained in advance; or, the IAB DU may determine the TDD direction according to the transmission/reception of the configuration obtained 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 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, supposing that MT UL and DU DL are simultaneously carried out;

when the scheduling of the parent IAB node on the flexible resource of the IAB MT is DL, assuming that MT DL and DU DL are simultaneously carried out;

when the parent IAB node schedules on the flexible resource of the IAB MT, assuming that the IAB DU has no scheduling;

the determination of which hypothesis to use is based on the multiplexing capability of the IAB (multiplexing capability).

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

1) The Parent IAB node cannot schedule an IAB MT, at least in case the DU resource type configuration allows IAB DU scheduling.

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

Optionally, for the aggressiveness of IAB DU scheduling: when the IAB DU is scheduled, the parent IAB node can be assumed to have no scheduling; alternatively, when the IAB DU is scheduled, it can be assumed that the Parent IAB node is scheduled as UL/DL.

Alternatively, when the parent IAB node schedules IAB MT, it can be assumed that DU scheduling exists. Moreover, when the IAB DU is scheduled, the parent IAB node can be assumed to have no scheduling; alternatively, the IAB DU scheduling may assume that parent IAB node is scheduled as UL/DL.

Optionally, if the parent IAB node knows in advance whether the DU has scheduling, the scheduling aggressiveness of the parent IAB node may be correspondingly improved, for example, a scheduling plan (scheduling plan) for reporting the DU.

(3) If there is no priority relationship between the IAB MT and the IAB DU, the IAB MT and the IAB DU may be scheduled according to an agreed multiplexing case (multiplexing case). For example, it is always assumed that the data is transmitted or received simultaneously, or the multiplexing case between the IAB MT and the IAB DU is determined according to the CU/parent multiplexing mode (multiplexing mode) indication, or the multiplexing case between the IAB MT and the IAB DU is determined according to the expected multiplexing mode reported by the IAB.

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

In another embodiment, in the above scheme, that is, at a certain time, the resources of the IAB MT are flexible resources, and the resources of the IAB DU are DL resources. The IAB node may determine a Time Division Duplex (TDD) direction of the IAB MT on the corresponding flexible resource according to the DCI indication obtained 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 indication obtained 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. Here, the corresponding flexible resource is a resource that 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 resources of the IAB MT are flexible resources, and the resources of the IAB DU are UL resources. The IAB node may determine the TDD direction of the IAB MT on the corresponding flexible resource according to the DCI indication obtained in advance. Or, the IAB node may determine the TDD direction of the IAB MT on the corresponding Flexible resource according to the DCI format 2-0 indication obtained 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. Here, the corresponding flexible resource is the same time domain resource as the UL resource of the IAB DU.

It should be noted that, in the fifth scenario, that is, at a certain time, the resources of the IAB MT are flexible resources, and the resources of the IAB DU are flexible resources. If the flexible resources of the IAB DU are default or assumed to be DL resources, since the resources of the IAB MT are flexible resources, similar to the first solution, the corresponding method is the same as the next solution. If the flexible resources of the IAB DU are default or assumed to be UL resources, since the resources of the IAB MT are flexible resources, the method is similar to the method of the second scheme, and the corresponding method is the same as the method of the second scheme.

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

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

when the default first resource is UL or DL resource and DL transmission of the IAB MT is scheduled and/or configured on the first resource, the IAB MT receives on the first resource;

when no UL transmission of the IAB MT is scheduled and/or configured on the first resource and the first resource is a DL resource by default, the IAB MT receives on the first resource;

when no UL transmission of the IAB MT is scheduled and/or configured on the first resource and the first resource is defaulted to be 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 transmit and receive on the first resource;

the IAB MT performs a first operation on the first resource according to the multiplexing capability and/or a preset rule of the IAB node. For example, the preset rule may include at least one of: 1) Under the condition that default MT UL and DU DL are simultaneously carried out, the IAB MT transmits UL, or the parent IAB node schedules the IAB MT to transmit UL on flexible resources; 2) Under the condition that default MT DL and DU DL are simultaneously carried out, the IAB MT receives DL, or the parent IAB node schedules the IAB MT to receive DL on flexible resources; 3) In case of no transmission of default IAB DU, parent IAB node schedules IAB MT on flexible resources, i.e. independent of IAB DU transmission.

Optionally, when the second resource is configured as an UL resource (corresponding to the second scheme, or the second resource is configured and/or indicated as a flexible resource (corresponding to the fifth scheme), 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 UL or DL resource and DL transmission of the IAB MT is scheduled and/or configured on the first resource, the IAB MT does not receive on the first resource;

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

when no DL transmission of the IAB MT is scheduled and/or configured on the first resource and the first resource is a UL resource by default, the IAB MT transmits on the first resource;

when no DL transmission of the IAB MT is scheduled and/or configured on the first resource and the first resource is a flexible resource by default, the IAB MT does not transmit and receive on the first resource;

the IAB MT performs a first operation on the first resource according to the multiplexing capability and/or a preset rule of the IAB node. For example, the preset rule may include at least one of: 1) Under the condition that default MT UL and DU UL are simultaneously carried out, the IAB MT transmits the UL, or a parent IAB node schedules the IAB MT to transmit the UL on flexible resources; 2) Under the condition that default MT DL and DU UL are simultaneously carried out, the IAB MT receives DL, or the parent IAB node schedules the IAB MT to receive DL on flexible resources; 3) In case of no transmission of default IAB DU, parent IAB node schedules IAB MT on flexible resources, i.e. independent of IAB DU transmission.

Optionally, the IAB MT may perform the first operation on the first resource if 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. For example, the priority rule for DU transmission and MT scheduling may be that DU transmission takes priority or MT scheduling takes priority.

IAB MT is scheduled by parent IAB node in case there is a transmission of default IAB DU.

Optionally, 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 DU is transmitted and/or received on the second resource according to scheduling by the IAB MT.

Alternatively, in this 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 priority or the IAB DU priority is determined according to a preset method, such as predefined, pre-configured and/or configured IAB MT priority or IAB DU priority, or default (or referred to as assumed) IAB MT priority or default IAB DU priority.

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

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

1) The default IAB MT resource is DL/UL, or, the parent IAB node is assumed to schedule the IAB MT resource to be UL/DL. At this time, the transmission of the IAB DU is guaranteed by taking the transmission of the IAB DU as a standard, and the half duplex of the IAB node is guaranteed, so that 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 information.

Optionally, if the IAB MT receives the DCI schedule or the DL transmission of the higher-layer configured 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/higher layer configured IAB MT is UL scheduling, it is assumed that the resource of the IAB MT is DL or flexible. There is no distinction between higher layer signaling/physical layer signaling, and it is believed that all signaling should be observed.

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

Optionally, 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 on the symbol. That is, the IAB node does not expect the parent IAB node to schedule the MT, at least in case the DU resource type configuration allows for DU transmission. The IAB MT does not transmit or receive on the flexible system, which is equivalent to the function of the flexible system indicated by the DCI as the NA in the MT, thereby ensuring the transmission of the DU.

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

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

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

5) If the parent IAB node acquires the DU in advance without transmission, the parent IAB node can schedule the flexible symbol of the IAB MT to be UL/DL/flexible. Wherein, the information that the DU is not transmitted may be that the DU is reported to the parent IAB node.

(2) If IAB MT precedence is predefined, preconfigured and/or configured:

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

a) The IAB DU is not transmitted and received on the corresponding symbol. That is, no matter whether the DU resource type configuration allows the transmission of the IAB DU, the IAB DU is not transmitted and received on the corresponding symbol.

b) And the IAB DU is transmitted and/or received on the corresponding symbol according to the scheduling of the IAB MT. That is, if the DU resource type configuration allows 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, and/or the IAB DU cannot determine whether the flexible symbol of the IAB MT is scheduled as UL or DL. In this case, scheduling may be performed only if the IAB node supports full duplex, otherwise scheduling may not be performed with a high probability. For another example, the IAB DU can determine whether the flexible symbol of the IAB MT is scheduled or not, and/or transmit the IAB DU according to the scheduler of the IAB MT when determining whether the flexible symbol of the IAB MT is scheduled to be UL or DL.

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

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

b) Under the condition that default MT DL and DU DL are simultaneously carried out, the IAB MT receives DL, or the parent IAB node schedules the IAB MT to receive DL on a flexible symbol;

c) In case of default IAB DU transmission, parent IAB node schedules IAB MT on flexible symbol, i.e. independent of IAB DU transmission.

For another example, taking the first resource and the second resource as symbols, under the second scheme, namely that part of the resources configured or indicated by the CU/parent IAB node for an IAB DU is UL symbols, and the parent IAB node configures or indicates that the corresponding IAB MT resource for the part of resources is flexible symbols:

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

1) The resources of the IAB MT are UL/DL by default.

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

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 sends information on the corresponding flexible symbol.

Note that, regarding the default IAB MT resource as 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/higher-layer configured IAB MT 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.

Optionally, if the default corresponding flexible symbol is a 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 on the symbol. That is, the IAB node does not expect the parent IAB node to schedule the MT, at least in case the DU resource type configuration allows DU transmission.

5) If the parent IAB node acquires the DU in advance without transmission, the parent IAB node may schedule the flexible symbol of the IAB MT to be UL/DL/flexible. Wherein, the information that the DU is not transmitted may be that the DU is reported to the parent IAB node.

(2) If IAB MT precedence is predefined, preconfigured and/or configured:

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

a) The IAB DU is not transmitted and received on the corresponding symbol. That is, no IAB DU transmission is allowed by the DU resource type configuration, no IAB DU transmission and no IAB DU reception is transmitted on the corresponding symbol.

a) Under the condition that default MT UL and DU UL are simultaneously carried out, the IAB MT transmits the UL, or a parent IAB node schedules the IAB MT to transmit the UL on flexible resources;

b) Under the condition that default MT DL and DU UL are simultaneously carried out, the IAB MT receives DL, or a parent IAB node schedules the IAB MT to receive DL on flexible resources;

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

In the embodiment of the present application, the IAB node may receive scheduling signaling, such as scheduling signaling of the IAB MT, from the parent IAB node. The scheduling signaling of the IAB MT may be determined by the parent IAB node according to the reported content of the IAB node and/or the actual scheduling of the IAB DU. 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) When the transmission time of the scheduling signaling of the IAB MT is M time units earlier than the transmission time of the IAB DU, the scheduling signaling of the IAB MT is a valid signaling.

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 configured by higher layers, parameters indicated by parent IAB node. The time units include but are not limited to: symbol, slot, frame, microsecond, millisecond, second, etc.

2) The IAB DU takes the latest received schedule of the valid IAB MT as the effective schedule.

3) The scheduled effective duration, the maximum value of the effective duration, or the minimum value of the effective duration of the IAB MT is at least one of: predefined parameters, pre-configured parameters, parameters for 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 mode of the IAB MT and the IAB DU may be a multiplexing mode of semi-static/dynamic configuration.

In the embodiment of the present application, four multiplexing manners of simultaneous transmission/simultaneous reception/transmission/reception of an IAB MT and an IAB DU may not be applied to a time domain resource configured by the IAB DU as a flexible symbol, or determine whether to apply to an IAB node according to an 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 resource indicated as the flexible resource. And/or the IAB node may determine, according to the indication of the parent IAB node and/or the donor IAB node, whether the multiplexing manner of the IAB MT and the IAB DU is applied to the configuration of the IAB DU and/or indicates the resource as the flexible resource. For example, the parent IAB node may indicate that the multiplexing method of simultaneous transmission/simultaneous reception is not applied to or applied to the configuration of the IAB DU and/or the resource indicated as 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 scheme is applied to the configuration of the IAB DU and/or to indicate a resource as a flexible symbol.

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

1) In the case that the second resource configuration and/or indication is DL resource (corresponding to the first scheme), or the second resource configuration and/or indication is flexible resource (corresponding to the fifth scheme), 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 some/all resources of the UL transmission of the higher layer configuration/DCI scheduling.

2) When the second resource configuration and/or indication is DL resource (corresponding to the above-mentioned solution one), or the second resource configuration and/or indication is flexible resource (corresponding to the above-mentioned solution five), 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 some/all resources of the DL transmission of the higher layer configuration/DCI scheduling.

3) In the case that the second resource configuration and/or indication is UL resource (corresponding to the second scheme), or the second resource configuration and/or indication is flexible resource (corresponding to the fifth scheme), 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 some/all resources of the DL transmission of the higher layer configuration/DCI scheduling.

4) In the case that the second resource configuration and/or indication is UL resource (corresponding to the second scheme), or the second resource configuration and/or indication is flexible resource (corresponding to the fifth scheme), 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 transmitted on part/all of the resources of the UL transmission for the higher layer configuration/DCI scheduling.

Optionally, 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 about transmission behaviors 1) to 4) are enabled. Specifically, the IAB node may receive first configuration information from the donor IAB node, where the first configuration information indicates that 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, the indication information indicating whether the multiplexing manner of the IAB MT and the IAB DU is applied to the IAB node or not.

In addition, the IAB node may also report its expected multiplexing scheme, thereby determining 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 first resource, which is a resource configured/indicated as a flexible resource for the MT, may satisfy at least one of:

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

For example, in the above scheme, that is, the second resource is configured and/or indicated as DL resource, if the resource type of the IAB DU is hard, the IAB MT is DL transmission; or, if the DCI indication/higher layer signaling schedules the IAB MT to receive DL information on a corresponding resource, such as PDSCH/PDCCH/CSI-RS/DL PRS, the IAB MT receives the information at a 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 on the corresponding resource, such as PUCCH/PUSCH/PRACH/SRS, the IAB MT transmits the information at the corresponding location.

b) The IAB MT performs a third operation when the second resource is configured as a Soft resource.

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., is considered a UL transmission. For example, if the DCI/higher layer scheduling IAB MT is transmitted on the corresponding symbol, the IAB MT is transmitted on the corresponding symbol.

When the IAB MT is scheduled and/or configured to receive on the first resource, the IAB MT receives on the first resource, i.e., considers a DL transmission. For example, if the DCI/higher layer scheduling IAB MT is received on a 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 scheduled IAB MT receives on part or all of the first resource, the IAB MT does not transmit on the first resource, or the IAB MT transmits on part of the first resource, which may refer to SRS transmission on part of the symbols. For example, if the higher layer scheduler IAB MT transmits on the corresponding symbol, and the IAB MT detects that the DCI scheduler receives 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 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 scheduling IAB MT receives on the corresponding symbol, and the IAB MT detects that the DCI schedules its transmission on part/all of the symbols, the IAB MT cannot receive on the corresponding symbol.

c) When the second resource is configured as the Not Available, MT executes the transmission behavior according to the preset rule, that is, the transmission behavior is consistent with the existing transmission behavior, and the transmission behavior of the IAB DU does Not need to be considered.

Optionally, in this 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 the IAB MT takes precedence or the IAB DU takes precedence 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 takes precedence or the IAB DU takes precedence according to a predetermined method. When the IAB node multiplexing limitation occurs, the IAB DU may be defined as downlink transmission.

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

1) And determining whether the IAB MT takes precedence or the IAB DU takes precedence according to the service load difference of a child link (parent link) and a parent link (parent link) of the IAB node.

For example, if the traffic load/delay on the child link of the IAB node is higher than the traffic load/delay on the parent link of the IAB node, it may be determined that the IAB DU uses resources preferentially over the IAB MT; otherwise, IAB, MT uses resources in preference to IAB DU.

2) And determining whether the IAB MT takes precedence or the IAB DU takes precedence according to the congestion states of the child link and the parent link of the IAB node.

For example, if congestion occurs on the child link of the IAB node and no congestion occurs on the parent link of the IAB node, the IAB DU preferentially uses the resource, and conversely, the IAB MT preferentially uses the resource.

3) And determining whether the IAB MT takes precedence or the IAB DU takes precedence according to the logical channel priorities of the sublink and the parent link of the IAB node.

For example, if the priority of the data to be transmitted on the child link of the IAB node is higher than the priority of the data to be transmitted on the parent link of the IAB node, the IAB DU preferentially uses the resource, and otherwise, the IAB MT preferentially uses the resource.

Alternatively, the CU may be configured to use or not use one or more of the methods of 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 the IAB MT priority or the IAB DU priority is used or not using a preset method.

Optionally, the IAB node may request the CU to configure one or more of the methods 1) to 3) above. 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 takes precedence or the IAB DU takes precedence.
