Background technique

Figure 1 is a schematic diagram of the relationship and links between multiple nodes in an integrated access and backhaul (IAB) network in the related art. As shown in Figure 1, the three nodes from top to bottom are called the parent node (Father Node, or Parent Node), IAB node (IAB-Node) and child node (Child Node). IAB-Node is the current node as a reference, and the upper-level node of IAB-Node is called Father Node. The current link between the IAB-Node and Father Node is called the backhaul link, which is divided into the backhaul downlink (backhaul (DL)) and the backhaul uplink (UL) from the transmission direction. )). The current link between the IAB-Node and the next-level node Child of this IAB-Node is called the access link (access link), and is further divided into access downlink (access) and access from the transmission direction. Uplink (access UL).

The judgment of link attributes is based on the relative relationship and role of nodes. If the Child Node in Figure 1 is an ordinary terminal, the link between the Child Node and the upper-level node is an ordinary access link for the Child Node, if the Child Node is regarded as the current node , Then this link between the Child Node and the upper-level node is the backhaul link. In Rel-14, the backhaul link and access link of relay nodes are time-division multiplexed. For the New Radio (NR) IAB network, due to the introduction of multi-hop relays, the relationship between the 3rd generation partnership project (3rd generation partnership project, 3gpp) and resource allocation is from the two functional units of the IAB node , That is, distributed unit (Distributed Unit, DU) and mobile terminal (Mobile Terminal (MT) point of view consider resource allocation, high priority to consider the resource allocation of DU and MT time division, but the DU resource configuration must ensure forward compatibility .

For the resource attributes identified by the DU resource include hard and soft attributes, this disclosure describes the configuration of the DU resource and the dynamics of the DU soft resource.

One potential technology for future network deployment is to support wireless backhaul to achieve flexible and dense deployment of NR cells without having to scale the transmission network.

IAB node is recognized as MT and DU functional unit, where MT is the unit that acts as UE function in IAB node, so its resource configuration method can follow the resource configuration method of Rel-15, and the DU unit is introduced as shown in Table 1. Attributes:

Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict.

In one embodiment, it can be seen from Table 1 that the resource attributes of DU are roughly divided into D, F, U, and NA, and the attributes of D, F, and U are further subdivided into Hard and Soft. Among them, HardDL can be directly used for the downlink scheduling of the access of its child node for the DU functional node. This resource DU does not need to consider the resource allocation of the MT. Hard UL and Hard F have the same meaning, that is, on the resource of the Hard attribute, the DU can perform the uplink and downlink scheduling of the access of the child node without considering the resource allocation of the MT.

For resources with soft attributes, taking Soft DL as an example, whether the resource is available to the DU requires further indication from the parent node.

Table 7: Expand the SFI field of 3gpp R15

By expanding the above Table 7, the DCI dynamic indication NA can appear at both ends of the time slot at the same time. It should be noted that the above Table 7 does not exhaust all the cases where F is in a time slot. The expansion of Table 7 is mainly reflected in that two Fs appear in two segments of the time slot. The above Table 7 does not limit the present disclosure. It is also within the protection scope of the present disclosure for other combinations of F to exist at both ends of one time slot.

Alternative Embodiment 13

The idea is the same as that in Embodiment 11. The difference is that DCI signaling no longer uses the DCI used by R15 to indicate SFI, and adopts a new design format, one of which is shown in Table 8 below.

Table 8

In addition, it is also equivalent to optional embodiment 4, and also needs to be configured to parse the DCI for dynamic indication of DU Soft resources. In addition, considering the indication form of the slot level, the format does not follow 2-0.

Alternative Embodiment 14

It should be noted that the idea is equivalent to that of the optional embodiment 13, except that the availability of Soft resources is indicated with the time slot as the granularity, and the scope of action is the overlapped Soft resources within the time slot.

In this way, 0 and 1 bits are used to indicate the Soft resource availability of the corresponding time slot. The design of each symbol in the time slot is omitted. A configuration is shown in FIG. 13, which is used to indicate that the boundary of the frame structure does not need to be aligned with the boundary of the usability indication, and the effective position is the area that overlaps with Soft, as shown in FIG. 13 Layer indication indicates that field 1 overlaps, and these Soft resources are understood to be indicated as IA, while other Soft DL resources overlap with physical layer indication field 0, and Soft resources in these areas are understood to be indicated as INA. The combination relationship between Soft F and Soft UL and physical layer fields is the same as Soft DL.

Alternative Embodiment 15

The scheduling time window of the MT is agreed or configured, and the MT unit of the IAB identifies the scheduled soft resource and the unscheduled soft resource in the receiving window. The MT can determine which resources are used for MT transmission, and these resources are released to the DU unit for the DU to call the child node.

One way is that the scheduling direction follows the transmission direction corresponding to the Soft resource. The process of determining the availability of the Soft resource is shown in FIG. 14. The DU resource of the IAB includes the Hard attribute and the Soft attribute. A time window is agreed. When the time window arrives, the MT determines Whether the Soft resource is scheduled. In this implementation, after the time window is determined, it is determined that the fifth time slot in FIG. 14 is not scheduled (not scheduled for this slot). The IAB determines that this resource is available for the DU (attribute is IA). That is to implicitly determine the availability of DUsoft resources. Similarly, when the next time window arrives, it is determined that the sixth time slot is scheduled by the parent node, then this Soft attribute resource is not available to the DU (attribute is INA).

In FIG. 14, taking only soft UL resources as an example to illustrate the identification of DU resource attributes when the time window arrives. Soft resources in the DL and UL directions also use the same criteria to determine the availability of Soft resources.

The discrimination window shown in FIG. 14 is 4 time slots. This value can be an agreed value or can be configured to the IAB node through signaling. The value 4 is only used to explain the invention, and does not limit the invention.

The selection of values can also consider the following factors.

The child node reports the expected decision window length to the parent node.

The child node reports the processing power to the parent node.

The transmission direction corresponding to the Soft resource, that is, the DL, UL, and F configurations or different decision window lengths are negotiated or agreed.

For example, when an IAB node has a long scheduling preparation time, this node should negotiate a longer decision window, otherwise this node can negotiate a shorter time window. When node 1 reports a lower processing capacity, its parent node is recorded as node 2 and a longer preparation time should be reserved. node 2 should be reported to the higher node as node 3 to apply for a longer decision window.

Alternative Embodiment 16

For a certain time unit, the 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 1-9, or may be a specific time granularity within the period, such as a time slot or a time slot + OFDM symbol(s) combination.

For a certain time unit, its MT resource configuration is one of the following attributes: D, F, U.

For MT, the basic time unit is a time slot, but the time unit here is not limited to a time slot. It can be an uplink and downlink configuration period or a specific time slot or time slot + OFDM symbol(s) combination within the period.

DU resources and MT resources conflict due to the following situations.

The Hard attribute resource of the DU conflicts with the MT resource. At this time, the Hard resource has high priority.

The DL or UL resource of the Soft attribute of the DU conflicts with the resource of the MT. If the Soft resource is indicated as IA (explicit or implicit, as described in Embodiments 10 to 15), the DU Soft resource has a high priority .

The F resource of the Soft attribute of the DU conflicts with the D/U resource of the MT, and the MT has semi-static uplink and downlink transmissions, the MT has a high priority, otherwise the DU has a high priority.

If the F resource of the Soft attribute of the DU conflicts with the F resource of the MT, and the MT has semi-static uplink and downlink transmissions, the MT has a high priority, otherwise the DU has a high priority.

The high priority gives priority to the sending and receiving operations without considering the operations corresponding to the low priority resource attributes.

Alternative Embodiment 17

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

IAB receives the combination of IDs for the DU resource regarding the resource indication

slotFormatCombinationsDU is a combination of slot and format configured for DU. One combination contains one or more SFIs. When multiple SFIs are included, the meaning is the corresponding SFIs in sequence by slot.

The IAB node receives the {HD, SD, HF, SF, HU, SU} configuration, and further the parent node informs the availability of DU Soft through physical layer signaling. The signaling structure uses the DCI2-0 format, which is called here DCI2-0-DU.

Payload size, RNTI is configured by RRC signaling, the format is as follows.

The IAB node receives the SFI scrambled corresponding to the DU resource configuration RNTI, the IAB learns the location of the DCI used to indicate the DU Soft resource, and demodulates the DCI2-0-DU to determine the frame structure configuration of several consecutive slots. The frame structure configuration will indicate a Or the SFI index of several consecutive time slots, the slotFormatCombinationId of the 5G NR system corresponds to the SFI index corresponding to a series of consecutive time slots, and the IAB node translates these index values into 8-bit binary number strings, each bit corresponds to a slot of soft Resource indication. For the IAB DU, the DL, UL, and F of the frame structure are understood as indications corresponding to Soft resources, where DL and UL are understood as indicating the Soft position as IA, and F is understood as indicating the Soft position as INA.

Based on this, the method for resource configuration in this optional embodiment includes the following steps.

Step S402: Receive the SFI index corresponding to one or several consecutive time slots of the SlotFormatCombinationsPerCell-DU configuration identification index.

Step S404: Receive the DU-SlotFormatIndicator-DU configuration and learn the load, ID and location information of the control corresponding to the local node.

In step S406, the corresponding SlotformatCombinantionID is analyzed to identify the SFI index corresponding to one or several time slots.

In step S408, these SFI indexes are converted into binary digits, and each SFI index value corresponds to 8 binary numbers. If there are multiple SFIs, these binary numbers are concatenated.

In step S310, each bit corresponds to the INA and NA states of several slots in a certain receiving position as the starting slot, where 1 indicates that the corresponding slot resource is IA, and 0 indicates that the corresponding slot soft resource is INA.

Based on the above steps S402 to S410, the CU or parent node performs some SFI combination configuration on the DU frame structure, and notifies the information required for demodulating the DU frame structure configuration; wherein, the information includes: control of the DU frame structure The load of the signal; indicates the position of the SlotformatCombinationID of the DU frame structure in the control information; the ID used to demodulate the control information of the DU.

The IAB node can demodulate the SlotformatCombinationID to know the frame structure configuration index of one or more consecutive slots. The IAB node converts the frame structure configuration indexes of these one or more consecutive slots into bit strings, and each frame structure index corresponds to several bits. In this embodiment, a slot frame structure index is converted into an 8-bit binary number string. If the frame format combination index corresponds to multiple frame structure configuration indexes, these binary number strings are concatenated to form the soft resource indicator bits of consecutive slots starting from this slot, where 1 indicates the corresponding soft resource if there is a soft resource in the corresponding slot For IA, 0 means that if there is a soft resource in the corresponding slot, the corresponding soft resource is INA.

In this embodiment, the conversion of the frame structure index corresponding to the frame structure combination index into an 8-bit binary number string is only for the convenience of explaining a specific value of the embodiment, and its value does not limit the protection scope of the present disclosure.

If the soft resource is dynamically indicated as D or U, the direction of the DU resource is the direction indicated by DCI.

In summary, the configuration of the DU corresponding to the time slot can determine the composition of the DU resources of a time slot. If there is Table 9, it can be seen that the resources in the time slot can be one or more of the DU attributes. If the DU resource attribute of some time slots is not configured, the default time slot defaults to the NA attribute.
