Description

Method and device for resource allocation, storage medium and electronic device

Technical Field

The present disclosure relates to the field of communications, and in particular, to a method and apparatus for resource allocation, a storage medium, and an electronic device.

Background

Fig. 1 is a schematic diagram of the relationship and links of each Node in an IAB (Integrated Access and Backhaul ) network in the prior art, and as shown in fig. 1, three nodes from top to bottom are respectively called a Father Node, an IAB-Node and a Child Node, the IAB-Node is a current Node serving as a reference, and a previous Node is called a Parent Node. The current link between the IAB-Node and the Parent Node is called a backhaul link, and is further divided into a backhaul DL and a backhaul UL from the transmission direction; the link between the current IAB-Node and its Child Node is called an access link, and is further divided into an access DL and an access UL from the transmission direction.

The judgment of the link attribute is based on the relative relation and role of the nodes, if the Child Node in fig. 1 is a common terminal, the link is a common access link, and if the Child Node is an IAB Node, the link is a backhaul link from the IAB Node. In Rel-14, the backhaul and access links of a Relay node are time division multiplexed. In contrast, for the NR IAB network, due to the introduction of multi-hop relay, the relation of 3gpp with respect to the resource configuration is that the resource configuration is considered from the perspective of two function units DU (Distributed Unit) and MT (Mobile Terminal) of the IAB node, and the resource configuration of the time division of the DU and MT is considered with high priority, but the resource configuration of the DU is guaranteed to be forward compatible.

The resource attributes identified for the DU resource include both hard and soft attributes, and the present disclosure describes the configuration of the DU resource as dynamic as the DU soft resource.

One potential technique for future network deployment is to support wireless backhaul to enable flexible and dense deployment of NR cells without scaling the deployment of transport networks.

The IAB node is identified as an MT and a DU functional unit, where the MT is a unit serving as a UE function in the IAB node, so that the resource configuration manner thereof may take over the resource configuration manner of Rel-15, and for the DU unit, since the attribute shown in table 1 is introduced:

Hard DL

Soft DL

Hard F

However, there is no effective solution in the related art how to configure the resource attribute of the DU.

Detailed Description

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

Example 1

First, for how resources of these properties of DUs are configured in the related art, two ways are given in this disclosure: (1) entirely new signaling; (2) a combination of original signaling and newly added signaling.

Further, it can be seen from table 1 that the resource attributes of DUs are roughly divided into D, F, U, NA, where the attributes of D, F, U are subdivided into Hard and Soft. The Hard DL can be directly used for downlink scheduling of access link of child node of DU function node, and the resource DU does not need to consider the resource allocation condition of MT. The Hard UL and Hard F have the same meaning, namely, on the resources with Hard attribute, DU can perform access link uplink and downlink scheduling of child node without considering the resource allocation condition of MT.

For Soft attribute resources, taking Soft DL as an example, whether such resources are available for DUs requires a further indication of parent node. Accordingly, the present disclosure has been made in order to achieve the solution to the problems in the related art described above from the following aspects: (1) resource allocation of DU; (2) dynamic indication of DU Soft resources; (3) resolution criteria when DU resources conflict with MT resources.

Alternative embodiment 8

The present alternative embodiment implements the indication of DU resources by introducing signaling 1 in combination with the original frame structure configuration signaling, which includes TDD-UL-DL-configuration command for common configuration and TDD-UL-DL-configuration defined for specific node configuration, and DCI 2-0 for dynamic signaling indication.

Signaling 1 indicates the time domain position of the { NA, hard, soft } attribute resource within one period, and the IAB receives signaling of the frame structure configuration. The specific configuration of DU resources in one period is determined by the frame structure configuration and { NA, hard, soft } attribute configuration.

One form of signaling 1 is as follows:

the above-mentioned DUConfig signaling structure gives { NA, hard, soft } resource attribute configuration with granularity of time slot, and the signaling structure has no periodicity, and defaults to use the same period as TDD-UL-DL, where the TDD-UL-DL period is the period of the value TDD-UL-DL-configuration command, and if only pattern1 is defined, the corresponding period is P, and if pattern1 and pattern2 are defined at the same time, the period of DUConfig is p+p2.

Signaling is introduced to indicate the corresponding locations of NA, hard and Soft resources. The attribute of a resource is either Soft or Hard or NA, but only one of the three. The signaling 1 is indicated by a slot form, such as a slot number of the Hard attribute, a slot number of the Soft attribute, and a slot number of the NA attribute in one period.

Further, the IAB node receives the TDD frame structure configuration and analyzes the uplink and downlink configuration conditions of the corresponding resources, and in this embodiment, the TDD-UL-DL-configuration Common or the TDD-UL-DL-configuration Common and the TDD-UL-DL-configuration Dedioded signaling are analyzed. The final resource attribute is determined by combining the two resource configurations.

Fig. 10 is a schematic diagram eight of a configuration of a DU resource according to an embodiment of the disclosure, as shown in fig. 10, where a final resource attribute of a resource overlapping with NA is NA, and if an uplink/downlink configuration of a certain resource is D and the DU resource is Soft, a final state of the resource is Soft D. HD, SF, HU and SU in fig. 10 above are abbreviations for Hard DL, soft F, hard UL and Soft UL, respectively. Resource attributes not shown in fig. 10 include SD (Soft DL) and HF (Hard F).

Alternative embodiment 9

The implementation realizes the indication of DU resources by introducing signaling 1 in combination with the original frame structure configuration signaling, which comprises TDD-UL-DL-configuration Common for public configuration and TDD-UL-DL-configuration Dediminated for specific node configuration and DCI 2-0 for dynamic signaling indication.

One form of signaling 1 is as follows:

the above-mentioned DUConfig signaling structure gives { NA, hard, soft } resource attribute configuration with time slot as granularity, and signaling 2 is TDD-UL-DL-ConfigDU or TDD-UL-DL-ConfigDU and TDD-UL-DL-ConfigDU-Dedicated. For the DU unit of the IAB node, there is the uplink and downlink configuration signaling for DU alone, and in this way, the resource configuration of DU is not limited and the resource configuration of MT unit is not needed.

Signaling 1 has no periodicity, and default uses the same period as TDD-UL-DL, which is the period of the value TDD-UL-DL-configuration du, with the corresponding period P if pattern1 is defined only, and the period p+p2 if pattern1 and pattern2 are defined simultaneously.

Signaling 1 indicates NA, hard, and Soft resource locations. The attribute of a resource is either Soft or Hard or NA, but only one of the three. The signaling 1 is indicated by a slot form, such as a slot number of the Hard attribute, a slot number of the Soft attribute, and a slot number of the NA attribute in one period.

Fig. 11 is a schematic diagram of configuration of a DU resource according to an embodiment of the disclosure, as shown in fig. 11, where a final resource attribute of a resource overlapping with NA is NA, and if an uplink/downlink configuration of a certain resource is D and the DU resource is Soft, a final state of the resource is Soft D. HD, SF, HU and SU in fig. 11 above are abbreviations for Hard DL, soft F, hard UL and Soft UL, respectively. Resource attributes not shown in fig. 11 include SD (Soft DL) and HF (Hard F).

The signaling 1 in the embodiment is only a specific form given for describing the scheme, and does not limit the invention itself. The scheme such as the implicit indication of the NA field in embodiment 1 is also applicable to this embodiment. Note that, in alternative embodiment 4, the resource indication manner according to slot+ofdm symbol is also applicable to this embodiment.

Alternative embodiment 10

The IAB node determines the H/S D/F/U and NA attributes of the resource according to the above-described alternative embodiments 1-9 or a combination thereof, and determines the resource location of the soft D/F/U therefrom. The present embodiment further increases availability of DU Soft resources by employing the signaling structure of NR DCI 2-0.

IAB node further receives { HD, SD, HF, SF, HU, SU } configuration about physical layer signaling, further parent node informs availability of DU Soft through physical layer signaling, signaling structure adopts DCI2-0 format, which is referred to herein as DCI2-0-DU

Its payload size, RNTI is configured by RRC signaling in the following format

The IAB node receives the SFI scrambled by the corresponding DU resource configuration RNTI, the IAB knows the position of the DCI used for indicating the DU Soft resource, demodulates the DCI2-0-DU and determines the frame structure configuration of a plurality of continuous slots, and the frame structure configuration can indicate whether the symbols in the slots are DL, F or UL. For an IAB DU, DL, UL and F of the frame structure are understood as indications of corresponding Soft resources, where DL and UL are understood as indicating Soft position as IA and F is understood as indicating Soft position as INA.

Fig. 12 is a schematic diagram of a configuration of DU resources according to an embodiment of the present disclosure, as shown in fig. 12, a time domain unit corresponding to a Soft D position has a physical layer uplink and downlink configuration D, and the final state of the units is Soft D further indicated as IA, where this resource DU can be used for DL link scheduling of its child node. Soft D corresponds to a position, some time domain units are configured as F corresponding to physical layer uplink and downlink, the final state of these units is Soft D further indicated as INA, and this resource DU cannot be used for DL link scheduling of its child node. Similarly, if some of the physical layers corresponding to Soft F are configured as F in uplink and downlink, the final state of the time domain units is Soft F further indicated as INA, and other of the physical layers corresponding to Soft F are configured as U in uplink and downlink, the final state of the corresponding time domain units is Soft F further indicated as IA. The resource of Soft U and the combination of physical layer uplink and downlink configuration are deduced in the same way.

The DFU indicating behavior of DCI can be extended to indicate not only whether IA or not but also further rewriting of the state.

Alternative embodiment 11

The main process is the same as that of the alternative embodiment 10, but the physical layer uplink configuration can rewrite the direction of Soft resources, as shown in fig. 12 of embodiment 10, some time domain units corresponding to the Soft D corresponding positions are configured as D corresponding to the physical layer uplink and downlink, the final states of the units are Soft D further indicated as IA, and this resource DU can be used for DL link scheduling of its child node. Some time domain units at the corresponding position of Soft D are configured as F corresponding to the physical layer uplink and downlink, the final state of the units is Soft D further indicated as INA, and this resource DU can not be used for DL link scheduling of its child node. Similarly, if some of the physical layer uplink and downlink corresponding to Soft F are configured as F, the final state of the time domain units is Soft F further indicated as INA, and other of the physical layer uplink and downlink corresponding to Soft F are configured as U, the final state of the corresponding time domain units is Soft F further indicated as UL IA, that is, the resources of these time domain positions are used for UL scheduling of child node.

Alternative embodiment 12

Table 6: SFI portion configuration of 3gpp R15

The configuration of R15 is extended based on the above analysis considerations, one extended configuration is as follows:

table 7: extending SFI field of 3gpp R15

By expanding the above table 7, it is possible to realize that DCI dynamically indicates NA simultaneously appear at both ends of a slot. It should be noted that, the above table 7 does not have all cases of exhaustion of F in one time slot, and the expansion of table 7 is mainly implemented in that two F blocks are respectively present in two segments of a time slot, the above table 7 does not limit the present disclosure, and other combinations in which F exists at two ends of one time slot are also within the scope of the present disclosure.

Alternative embodiment 13

The idea is similar to embodiment 11, except that the DCI signaling does not use R15 for indicating the DCI of the SFI any more, and a new design format is adopted, where one design manner is as shown in table 8 below:

TABLE 8

In addition, the same as in alternative embodiment 4, and DCI for interpreting the dynamic indication of the DU Soft resource needs to be configured. In addition, considering the indication form of the slot level, the format does not follow 2-0.

Alternative embodiment 14

Note that the concept is equivalent to the alternative embodiment 13, and the difference is that the availability of Soft resources is indicated with the granularity of time slots, and the scope of the effect is overlapping Soft resources in the time slots.

This way, soft resource availability of the corresponding slot is indicated directly with 0,1 bit. And each symbol design in the time slot is omitted. One configuration is shown in fig. 13, for indicating that the boundary of the frame structure does not require alignment with the boundary of the availability indication, and the active position is a region overlapping with Soft, as shown in fig. 13, a part of Soft DL resources is overlapped with the physical layer indication field 1, these Soft resources are understood as indicated as IA, and other Soft DL resources are overlapped with the physical layer indication field 0, and the Soft resources of these regions are understood as indicated as INA. Soft F and Soft UL are in the same combination with the physical layer field as Soft DL.

Alternative embodiment 15

The MT unit of the IAB agrees or configures a scheduling time window of the MT, and recognizes scheduled Soft resources and unscheduled Soft resources at a reception window. The MT can determine which resources are used for MT transmission, which are released to the DU unit for the DU to make child node calls.

One way is that the scheduling direction complies with the transmission direction corresponding to the Soft resource, the availability determination process of the Soft resource is as shown in fig. 14, the DU resource of the IAB includes a Hard attribute and a Soft attribute, a time window is agreed to arrive when the time window, the MT determines whether the Soft resource is scheduled, in this implementation, it is determined that the 5 th time slot in fig. 14 is not scheduled (not scheduled for this slot) after the arrival of the time window is determined, and the IAB determines that the resource is available to the DU (attribute is IA), that is, the availability of the DU Soft resource is determined in an implicit manner. Also, when the next time window arrives, it is determined that the 6 th slot is scheduled by the parent node, then this Soft attribute resource is not available for the DU (attribute is INA).

The identification of the DU resource attribute at the time of arrival of the time window is illustrated in fig. 14 using only soft UL resource as an example. The Soft resources in DL and UL directions also determine the availability of Soft resources with the same criteria.

The discrimination window shown in fig. 14 is 4 time slots, and this value may be a contracted value or may be configured to an IAB node through signaling, and the value 4 is only used to illustrate the invention and not to limit the invention.

The values may also be chosen taking into account the following factors:

the child node reports the expected judging window length to the parent node;

the child node reports the processing capacity to the parent node;

the transmission direction corresponding to Soft resources, namely DL, UL and F, configure or negotiate or agree on different decision window lengths.

For example, when the schedule preparation time of an IAB node is long, the node should negotiate a longer decision window, whereas the node may negotiate a shorter time window. When node 1 reports lower processing power, its parent node should reserve longer preparation time for node 2, and node 2 should apply for longer decision window to higher node, node 3.

Alternative embodiment 16

For a certain time unit, its DU resource configuration may include one of the following attributes: HD, SD, HF, SF, HU, SU, NA.

The certain time unit may be the DU period defined in embodiments 1 to 9, or may be a specific time granularity within the period, such as a slot or a slot+ofdm symbol(s) combination.

For a certain time unit, its MT resource is configured as one of the following attributes: d, F, U.

For MT, the basic time unit is a time slot, but the time unit is not limited to a time slot, and may be an uplink and downlink configuration period or a specific time slot or a combination of time slots and OFDM symbols(s) in the period.

The collision between the DU resource and the MT resource is generated by the following situations:

the Hard attribute resource of DU conflicts with the MT resource, and the Hard resource has high priority;

DL or UL resources of the Soft attribute of the DU collide with resources of the MT, if the Soft resource is indicated as IA (explicit or implicit, as described in examples 10-15) then the DU IA Soft resource has high priority;

f resources of the Soft attribute of the DU collide with D/U resources of the MT, and the MT has semi-static uplink and downlink transmission, so that the MT has high priority, otherwise, the DU has high priority;

f resources of the Soft attribute of the DU collide with F resources of the MT, and the MT has semi-static uplink and downlink transmission, so that the MT has high priority, otherwise, the DU has high priority.

The transceiving operation is performed with a higher priority without considering the operation corresponding to the resource attribute of the low priority.

Alternative embodiment 17

The IAB node determines the H/S D/F/U and NA attributes of the resource according to alternative embodiments 1-9, 18 or a combination thereof, from which the resource location of the soft D/F/U is determined. The present embodiment further indicates availability of DU Soft resources by employing the signaling structure of NR DCI 2-0.

IAB receives ID combinations for DU resources with respect to resource indications

The slot format combination DU is a slot format combination configured for DU, one combination contains one or more SFIs, and when the combination contains multiple SFIs, the meaning is SFIs corresponding in sequence according to slots.

IAB node receives { HD, SD, HF, SF, HU, SU } configuration about, further parent node signals availability of DU Soft through physical layer signaling structure in DCI2-0 format, referred to herein as DCI2-0-DU

Its payload size, RNTI is configured by RRC signaling in the following format

The IAB node receives the SFI scrambled by the corresponding DU resource configuration RNTI, the IAB obtains the position of the DCI used for indicating the DU Soft resource, demodulates the DCI2-0-DU to determine the frame structure configuration of a plurality of continuous slots, the frame structure configuration can indicate the SFI index of one or a plurality of continuous time slots, the slotFormat Combination Id of the 5G NR system corresponds to the SFI index corresponding to a series of continuous time slots, the IAB node translates the index values into a binary number string of 8 bits, and each bit corresponds to the Soft resource indication of one slot. For an IAB DU, DL, UL and F of the frame structure are understood as indications of corresponding Soft resources, where DL and UL are understood as indicating Soft position as IA and F is understood as indicating Soft position as INA.

Based on this, the method for resource allocation in this alternative embodiment includes:

step S402, receiving SFI indexes of one or a plurality of continuous time slots corresponding to the configuration identification indexes of SlotFormatCombinationsPercell-DU;

step S404, receiving DU-SlotFormatIndexter-DU configuration to acquire the control load, ID and position information corresponding to the node;

step S406, analyzing the corresponding SlotFormat combinerionID, and identifying SFI index corresponding to one or several time slots;

step S408, converting the SFI indexes into 2-system bit streams, wherein each SFI index value corresponds to 8 binary numbers, and if a plurality of SFIs exist, the binary numbers are connected in series;

in step S310, each bit corresponds to the INA and NA states of a plurality of slots in sequence with a certain receiving position being the starting slot, where 1 indicates that the corresponding slot resource is IA, and 0 indicates that the corresponding slot resource is INA.

Based on the above steps S402 to S410, the CU or parent node performs some SFI-combined configuration on the frame structure of the DU and notifies the necessary information for demodulating the DU frame structure configuration; among these information are: a load carrying control signals of the DU frame structure; indicating the position of the SlotFormat coding ID of the DU frame structure in the control information; an ID for demodulating the control information of the present DU.

The IAB node demodulates the SlotFormat Combination ID to obtain the frame structure configuration index of one or more continuous slots. The IAB node converts the frame structure configuration index of these one or more consecutive slots into a bit string, each frame structure index corresponding to a number of bits, in this embodiment one slot frame structure index is converted into an 8-bit binary string. And if the frame format combination index corresponds to a plurality of frame structure configuration indexes, connecting the binary number strings in series to form a soft resource indication bit of a plurality of continuous slots with the slot as a starting position, wherein 1 represents that the corresponding slot is IA if the soft resource exists, and 0 represents that the corresponding slot is INA if the soft resource exists.

The conversion of the frame structure index corresponding to the frame structure combination index into the 8-bit binary string in this embodiment is only for convenience of describing a specific numerical value of the embodiment, and the numerical value is not limited to the protection scope of the present disclosure.
