Referring to fig. 3, fig. 3 is a flowchart of a resource allocation method according to an embodiment of the present application, and as shown in fig. 3, the method includes the following steps:

301, the IAB node obtains frequency domain resource information;

an operating bandwidth of the MT of the IAB node;

a guard interval.

The IAB may acquire the frequency domain resource information configured by the parent node or the CU, or may acquire predefined frequency domain resource information.

In addition, at least one of the operating bandwidth and the guard interval may be an implicit or explicit indication of the frequency domain resource information.

The guard interval may be a guard interval between the DU of the IAB node and the working bandwidth of the MT.

In the embodiment of the present application, the working bandwidth of the MT may include: a size of the frequency domain resources and/or a location of the frequency domain resources. Similarly, the guard interval may include: a size of the frequency domain resources and/or a location of the frequency domain resources.

In the embodiment of the present application, the working bandwidth and the guard interval are configured for the MT independently, so that the resource configuration precision is improved, and the resource configuration effect for the IAB node is improved.

As an optional implementation manner, the frequency domain resource information includes at least one of the following:

first frequency domain resource information configured by father node for IAB node

Second frequency domain resource information configured by the centralized control unit CU for the IAB node;

protocol predefined third frequency domain resource information.

The parent node may be a previous hop of the IAB node, or may be a node of an N-hop of the IAB node, where N is an integer greater than 1, that is, there may be another IAB node between the parent node and the IAB node.

The parent node may configure the frequency domain resource Information through a Medium access Control element (MAC CE) or Downlink Control Information (DCI) signaling, or may configure the frequency domain resource Information through RRC signaling that conveys the CU.

The CU may configure the frequency domain resource information through F1-C or RRC signaling, or a Backhaul adaptive Protocol control packet data unit (BAP control PDU).

In addition, the resources of the guard frequency domain interval of the MT and DU of the IAB node may also be protocol defined.

In this embodiment, configuring the IAB with at least one of the operating bandwidth and the guard interval may be achieved in a variety of ways.

Optionally, when the IAB node obtains at least two items of the first frequency domain resource information, the second frequency domain resource information, and the third frequency domain resource information, the frequency domain resource information is frequency domain resource information determined in the at least two items according to a first signaling.

The first signaling may be additional indication signaling besides the frequency domain resource information, for example: one signaling configures the frequency domain resource information, and the other signaling indicates one of the at least two items, and one of the at least two items is adopted through the signaling indication, for example: the indication is to determine the working bandwidth and the guard interval of the MT by using frequency domain resource information predefined by a parent node, a CU or a protocol, such as 1 bit or 2 bits.

As an optional implementation, the guard interval is related to at least one of:

duplex mode of the IAB node;

a transmit power of at least one of the DU and MT of the IAB node;

a power spectral density of at least one of a DU and MT of the IAB node;

a beam direction of at least one of a DU and MT of the IAB node;

a beam index of at least one of a DU and MT of the IAB node;

a cell type of a serving cell;

a cell group type of a serving cell;

the working bandwidth of the MT and the relative location of the available frequency domain resources of the DU;

mode configuration of dual connectivity;

a frequency domain range.

The duplex mode between the guard interval and the IAB node may be, for example, the guard interval may be determined according to the duplex mode of the IAB node, and the method includes: different duplexing schemes may configure different guard intervals. For example: in a Frequency Division Multiplexing (FDM) Multiplexing scheme, a CU may configure at least one of the following for the IAB node:

protection bandwidth 1 corresponding to MT TX and DU TX;

protection bandwidth 2 corresponding to MT RX and DU RX;

protection bandwidth 3 corresponding to MT TX and DU RX;

MT RX and DU TX corresponding guard bandwidths 4.

The above-mentioned MT TX and DU TX may indicate that MT TX and DU TX are performed simultaneously, MT RX and DU RX may indicate that MT RX and DU RX are performed simultaneously, MT TX and DU RX may indicate that MT TX and DU RX are performed simultaneously, and MT RX and DU TX may indicate that MT RX and DU TX are performed simultaneously.

In addition, when the IAB node adopts a certain multiplexing scheme, the guard interval between the MT and the DU is the corresponding guard bandwidth x (x is 1 or 2 or 3 or 4).

It should be noted that, in the embodiments of the present application, there may be some duplexing modes without setting the guard interval.

The above-mentioned guard interval may be related to the transmission power of at least one of the DU and the MT of the IAB node, and the maximum or minimum value of the guard interval may be configured according to the transmission power of at least one of the DU and the MT.

The correlation between the above guard interval and the power spectral density of at least one of DU and MT of the IAB node may be that the maximum or minimum value of the bandwidth of the guard interval is configured according to the power spectral density of at least one of DU and MT.

The above-mentioned beam direction correlation of the guard interval and at least one of the DU and MT of the IAB node may be that the maximum or minimum value of the bandwidth of the guard interval is configured according to the beam direction of at least one of the DU and MT of the IAB node.

The above-mentioned guard interval may be related to a beam index of at least one of the DU and the MT of the IAB node, and the maximum or minimum value of the guard interval may be configured according to the beam index of at least one of the DU and the MT of the IAB node.

The serving cell may be a serving cell of the MT, and the cell type may be a primary cell or a secondary cell, for example: the above-mentioned guard interval is related to the serving cell of the MT being the primary cell or the secondary cell, and for example, different guard intervals may be configured for two different cases, that is, the serving cell of the MT being the primary cell and the serving cell of the MT being the secondary cell, and of course, in some embodiments, related guard intervals may also be configured.

The Cell Group type may be a Master Cell Group (MCG) or a Secondary Cell Group (SCI), for example: the above-mentioned guard interval is related to the serving cell of the MT belonging to the MCG or SCI, for example, different guard intervals can be configured in two different cases, that is, the serving cell for the MT belongs to the MCG and the serving cell for the MT belongs to the SCG, and of course, related guard intervals can also be configured in some embodiments.

The relative position of the above-mentioned guard interval and the working bandwidth of the MT and the available frequency domain resources of the DU may be related to that the above-mentioned guard interval is configured according to the relative position, for example: the working bandwidth of the MT and the available frequency domain resources of the DU are located in different carriers, and the frequency domain isolation between carriers can also be calculated as part of the guard interval.

The above-mentioned guard interval may be related to a dual connectivity mode configuration, and the corresponding guard interval may be configured for the IAB node according to the mode configuration, for example, different guard intervals are configured for different dual connectivity modes.

The frequency domain range may be an operating frequency band of the IAB node, for example: different guard intervals are configured according to whether the working frequency band of the IAB node is an FR1 frequency band or an FR2 frequency band. The FR1 is a Sub6GHz band, i.e., a low frequency band, and the FR2 is a millimeter wave (mmWave) band, i.e., a high frequency band.

In this embodiment, configuring an appropriate guard interval for the IAB node according to at least one item described above may be implemented to improve the working performance of the IAB node.

As an optional implementation, the method further comprises:

and the IAB node reports expected information to a father node or a CU, wherein the expected information is used for configuring the protection interval.

The configuration of the expectation information for the protection interval may be that the father node or the CU configures the protection interval for the IAB node with reference to the expectation information, so that the father node or the CU ensures the protection interval between the IAB node MT and the DU, and the purpose of resource coordination between the IAB node and the father node or the CU node is achieved.

Optionally, the desired information includes at least one of:

a guard bandwidth, a multiplexing mode, a duplex mode, a reference time of the desired information, and an effective time of the desired information.

The guard bandwidth may be a guard interval expected by the IAB node, and may also report parameter information of the guard bandwidth, for example: the parameter information related to the guard interval, such as the duplex scheme, the transmission power, the power spectral density, and the beam information.

The multiplexing mode may be a multiplexing mode under FDM, for example: the following modes may be included:

(DU)TX&(MT)TX、(DU)RX&(MT)RX、(DU)TX&(MT)RX、(DU)RX&(MT)TX。

wherein (DU) TX & (MT) TX may indicate that the DU transmission in the frequency domain range a is performed simultaneously with the MT transmission in the operating bandwidth B;

(DU) RX & (MT) RX may indicate that the DU is received in the frequency domain range a simultaneously with the MT's reception in the operating bandwidth B;

(DU) TX & (MT) RX may indicate that the DU is transmitting in the frequency domain range a simultaneously with the MT receiving in the operating bandwidth B;

(DU) RX & (MT) TX may indicate that the DU is received in the frequency domain range a simultaneously with the MT transmitting in the operating bandwidth B.

The frequency domain range a and the operating bandwidth B may be two different frequency domain resources with a minimum interval therebetween being the guard interval.

The reference time of the expected information may be a reference time point of the expected information, and the parent node or the CU may use the expected information when the reference time is reached after receiving the expected information. In addition, the reference time may be explicitly or implicitly carried in the report information.

The time for validating the expectation information may be a time for validating frequency domain resource information of the IAB node configured based on the expectation information. The validation time may be explicitly or implicitly carried in the reporting information.

For example: the IAB node reports the expected protection interval configuration to the father node or CU through MAC CE or RRC signaling, and the father node or CU configures the corresponding protection interval configuration to the IAB node after receiving the configuration. The expected guard interval may report only the guard interval value of the currently in-use multiplexing mode, or may report the guard interval values of all supported multiplexing modes of the IAB node. After the IAB node receives the guard interval value configured by the father node or the CU, the frequency domain resource is reserved by the guard interval value to serve as the guard interval.

As an optional implementation manner, the working bandwidth is explicitly or implicitly indicated by the frequency domain resource information of the parent node or the CU.

The explicit indication may be by configuration or dynamic indication, such as: indicated by BWP.

The implicit indication may be to exclude the available frequency domain resources of the DU and the frequency domain resources after the guard interval based on the explicitly indicated working bandwidth.

As an optional implementation, the operating bandwidth is related to a multiplexing mode of the IAB node.

The Multiplexing modes include FDM, Space Division Multiplexing (SDM), and Time Division Multiplexing (TDM).

And the above-mentioned frequency domain resource information acquisition mode can also be related to multiplexing mode.

In this embodiment, FDM, SDM, or TDM multiplexing is implemented by the above-described operating bandwidth.

For example: when FDM multiplexing is supported, the IAB node does not expect that the available frequency domain range of the IAB DU overlaps with the working bandwidth of the IAB MT; alternatively, the available frequency domain resources of the CU/parent configuration IAB DU do not overlap with the operating bandwidth of the IAB MT. Specifically, the FDM multiplexing may be implemented by the explicit or implicit configuration described above.

For example: when SDM multiplexing is supported, the available frequency domain range of the IAB DU may overlap the operating bandwidth of the IAB MT. The DU and MT are multiplexed in the overlapping frequency domain resources. In addition, additional indication signaling may be used to indicate whether the MT can use the overlapped part, if not, the DU and MT are switched back to FDM resource multiplexing, otherwise, SDM resource multiplexing. Alternatively, the MT is instructed to use only a part of the overlapping resources.

Optionally, the method further includes:

the IAB node reports expected information to a father node or a CU, wherein the expected information comprises at least one of the following items:

a desired multiplexing mode, and frequency domain resources corresponding to at least one multiplexing mode.

The desired multiplexing mode may be FDM or SDM, or TDM.

The frequency domain resource corresponding to the at least one multiplexing mode may be at least one of a size and a position of the frequency domain resource corresponding to each multiplexing mode.

In this embodiment, since the expected information is reported, the resource configuration information finally obtained can be easily matched with the expected information, so as to finally improve the working performance of the IAB node.

In addition, in this embodiment, the CU may notify the IAB node of the multiplexing method, for example: the IAB node is notified directly by the IAB node or by a parent node.

Optionally, the frequency domain resource information is further used for at least one of:

indicating that the working bandwidth can be used as FDM multiplexing resources under the condition that the IAB node supports FDM;

indicating that the working bandwidth can be used as SDM multiplexing resources in case that the IAB node supports SDM.

In this embodiment, since the operating Bandwidth is indicated as the FDM multiplexing resource, it is possible to indicate potential SDM multiplexing in advance before the available frequency domain resources of the IAB DU overlap with the operating Bandwidth of the IAB MT, so as to prepare for the handover of the Bandwidth fragment (BWP), thereby improving handover efficiency.

Since the operating bandwidth is indicated as the SDM multiplexing resource, it is possible to indicate the potential FDM multiplexing in advance before the available frequency domain resource of the IAB DU overlaps with the operating bandwidth of the IAB MT, so as to prepare for BWP handover, thereby improving handover efficiency.

Optionally, under the condition that the frequency domain resource information indicates that the working bandwidth can serve as FDM multiplexing resources and indicates that the working bandwidth can serve as SDM multiplexing resources, the IAB node determines that the working bandwidth can serve as FDM multiplexing resources or determines that the working bandwidth can serve as SDM multiplexing resources according to the indication information.

The indication information may be an additional indication signaling, so as to determine that the working bandwidth may serve as the FDM multiplexing resource or the working bandwidth may serve as the SDM multiplexing resource through the indication signaling.

As an optional embodiment, the operating bandwidth is related to a duplexing mode of the IAB node, where the duplexing mode includes: a duplex mode supported on the DU cell of the IAB node, or a duplex mode between the DU cell of the IAB node and at least one MT serving cell.

In the embodiment of the present application, the MT may support dual connectivity, for example, multiple MT cells correspond to one DU cell. The duplex mode between the DU cell and the at least one MT serving cell may be that the DU cell corresponds to a different duplex mode when corresponding to the MT serving cell, and may configure different MT working bandwidths.

Optionally, the frequency domain resource information is obtained according to a duplex mode.

In this embodiment, it can be realized that the working bandwidth and the guard interval of the MT can be independently acquired or notified for different duplexing modes. It should be noted that the different duplexing modes are not all duplexing modes, because in some scenarios, it is not excluded that a part of duplexing modes do not need to acquire or inform the MT of the operating bandwidth.

As an optional embodiment, the method further comprises at least one of:

the IAB node reports the working bandwidth to a father node;

the IAB node reports the acquisition mode of the frequency domain resource information to the father node;

the IAB node reports the working bandwidth to a CU;

and the IAB node reports the acquisition mode of the frequency domain resource information to the CU.

The above-mentioned acquisition method may also be understood as a notification method in which the parent node or the CU notifies the frequency domain resource information.

In this embodiment, since at least one of the working bandwidth and the above-mentioned acquisition mode is reported to the parent node, the parent node or the CU can control at least one of the available frequency domain resources and resource scheduling of the IAB DU according to the MT working bandwidth of the IAB, so as to implement the FDM and SDM multiplexing mode between the MT and the DU, or ensure that the frequency domain resource interval used by the DU and the MT meets the guard interval.

In addition, the IAB node reports the available frequency domain range of the IAB node to a parent node, and/or the IAB node reports the acquisition mode of the frequency domain resource information of the available frequency domain range of the IAB node to the parent node. Thus, since the information is reported to the father node or the CU, the father node or the CU can control BWP/resource scheduling of the IAB node MT according to the available frequency domain range of the IAB DU to implement the FDM/SDM multiplexing mode between the MT and the DU, or ensure that the frequency domain resource interval used by the DU and the MT meets the guard interval.

In one embodiment, a CU may notify the available frequency domain range of the DU of the parent node and/or the acquisition manner or notification manner of the available frequency domain range of the DU of the IAB node.

As an optional implementation, the validation time of at least one of the working bandwidth and the guard interval is configured by a CU or a parent node.

In this embodiment, configuring at least one of the working bandwidth and the guard interval to be effective only in the effective time may be implemented to further enhance the control of the working bandwidth and the guard interval.

Optionally, the CU or the parent node configures the validation time by at least one of the following parameters:

period indication, time domain offset, time domain resource size.

For example: the CU or the parent node may send the at least one indication parameter to the IAB node to configure the validation time. Specifically, the indication parameter may be configured through at least one of F1-C signaling, RRC signaling, BAP control PDU, and DCI. Additionally, the indicated granularity may be: m slots, N symbols, L milliseconds, K subframes, or a frames, etc., where M, N, L, K, a > is 1.

Optionally, at least one of the working bandwidth and the guard interval is valid for a time period in which the first duplexing mode is employed.

The first duplexing mode may be a predefined duplexing mode, which is not limited herein.

The embodiment may be such that, in a case where the configuration of at least one of the operating bandwidth and the guard interval is related to the first duplexing mode, at least one of the operating bandwidth and the guard interval is valid for a time period in which the first duplexing mode is employed. For example: if the first duplexing mode is adopted during the validation time, at least one of the working bandwidth and the guard interval is validated during the time adopting the first duplexing mode, and if the first duplexing mode is not adopted during the validation time, at least one of the working bandwidth and the guard interval is not validated.

Since at least one of the operating bandwidth and the guard interval is valid for the time in which the first duplexing method is employed, control of the operating bandwidth and the guard interval may be further enhanced.

The following illustrates the configuration signaling for configuring the guard interval of the IAB node as follows:

the CU may configure the frequency domain resource of the guard interval through F1-C or RRC signaling.

In one embodiment, the frequency domain resources of the CU via the F1-C signaling guard interval may specifically be as follows: the F1-C signaling may explicitly configure the frequency domain starting position and the frequency domain resource length indication, for example: the F1-C signaling may include the following configurations:

Frequency configuration item:

>Starting PRBs

>Number of PRBs

wherein, the staring PRBs are the frequency domain Starting positions;

number of PRBs is a frequency domain resource length indication;

alternatively, the CU may select to explicitly configure or implicitly configure the frequency domain starting position and the frequency domain resource length indication, and the F1-C signaling may include the following configurations:

BW1 is the configured first frequency domain resource bandwidth, BW2 is the configured second frequency domain resource bandwidth, and BW3 is the configured third frequency domain resource bandwidth. The configuration of BW1, BW2, and BW3 may be the same or different.

In another way, the CU may configure a guard interval frequency domain resource related to the multiplexing mode, and the signaling may include the following configuration:

Frequency configuration item:

>FDM ENUMERATED(BW1,BW2,BW3)

>SDM ENUMERATED(BW1,BW2,BW3)

>TDM ENUMERATED(BW1,BW2,BW3)

it should be noted that, the above is only an example of 3 bandwidth parameters, and is not limited to the configuration of selectable 3 bandwidths, and the number of selectable actually is an integer greater than or equal to 1.

Alternatively, a CU may configure guard interval frequency domain resources related to the duplex mode, for example: the duplex information element (multiplexing info IE) of the signaling includes the following configurations:

wherein BW1 is the first frequency domain resource bandwidth, BW2 is the first frequency domain resource bandwidth, BW3 is the first frequency domain resource bandwidth, and BW4 is the first frequency domain resource bandwidth. Taking four multiplexing manners as an example, the size of the specific bandwidth number (BW1-BW4) may not be 4, and may be more or less. Multiple multiplexing modes may correspond to one bandwidth configuration, which is not limited.

In the embodiment of the present application, the parent node may also refer to the signaling to configure at least one of the operating bandwidth and the guard interval for the IAB node.

In the embodiment of the application, an IAB node acquires frequency domain resource information; wherein the frequency domain resource information is used for indicating at least one of the following: the working bandwidth of the mobile terminal MT of the IAB node; a guard interval. Therefore, the working bandwidth can be configured for the MT independently, the guard interval can be configured independently, the resource configuration precision is improved, and the resource configuration effect for the IAB node is improved. Interference and delay in the system may also be reduced.

Referring to fig. 4, fig. 4 is a flowchart of another resource allocation method provided in the embodiment of the present application, and as shown in fig. 4, the method includes the following steps:

step 401, the target node configures frequency domain resource information for the IAB node;

Optionally, the guard interval is related to at least one of:
