Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, in particular to a method and apparatus for determining resources, a storage medium and an electronic device. BACKGROUND

[0002] One potential technology for future network deployment is to support wireless backhaul to enable flexible and dense deployment of NR cells (New Radio access technology cells) without scaling the transport network proportionally.

[0003] An IAB node (Integrated Access and Backhaul node) is identified as MT (Mobile Terminal) and DU (Distributed Unit) functional units, wherein the MT is a unit in the IAB node that functions as a UE, and the DU unit provides services for a child node as a base station function.

[0004] Figure 1 The relationship between nodes and links in the IAB network in the related art is shown in the schematic diagram as shown in FIG. 1. The three nodes from top to bottom are respectively called parent node, child node and the node served by the child node. The node served by the child node can be a terminal or an IAB node. The link between the child IAB node and its parent node is called a backhaul link, and is further distinguished as backhaul DL and backhaul UL from the transmission direction. The link between the child node and the node it serves is called an access link, and is further distinguished as access DL and access UL from the transmission direction.

[0005] The judgment of the link attribute is based on the relative relationship and role of the nodes. If the node served by the child node in the formula (1) is a normal terminal, then the link is an access link for the served terminal. If the node served by the child node is an IAB node, then from the perspective of this IAB node, the link is a backhaul link. Figure 1

[0006] ​In Rel-14, the backhaul and access link of the relay node are time-division multiplexed. For the NR IAB network, due to the introduction of multi-hop relays, 3gpp considers resource configuration from the perspective of the two functional units DU and MT of the IAB node, and gives priority to the resource configuration of the DU and MT time division. However, the resource configuration of the DU must ensure forward compatibility (FDM / SDM). The DU resource is the resource of the child node or terminal served by the DU functional unit of the IAB node. For example, the DL resource of the DU is the resource of the IAB DU functional unit scheduling the downlink transmission of the child node or terminal.

[0007] The resource attributes of the DU are divided into seven types: Hard DL, Hard F, Hard U, Soft DL, Soft F, Soft U, and NA. Among them, Hard DL can be directly used for downlink scheduling of the access link of the child node of the DU functional node. The 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 with the Hard attribute, the DU can perform downlink scheduling on the access link of the child node without considering the impact on the MT. The NA resource is not available to the child DU. The availability of the Soft resource to the child DU needs to be determined by the indication of the parent node. When the Soft resource is indicated as Available by the parent node, the resource is available to the child DU. If the Soft UL is indicated as Available, the child DU can use these resources for uplink scheduling of the child node or terminal. If the Soft DL is indicated as Available, the child DU can use these resources for downlink scheduling of the child node or terminal.

[0008] At present, there is no effective solution to the above problems in the related art. SUMMARY

[0009] The embodiments of the present application provide a method and device for determining resources, a storage medium and an electronic device, to at least solve the technical problem that the availability of resources is difficult to determine in the related art.

[0056] Embodiment 2

[0057] In this embodiment, a resource determining device is also provided, which is used to implement the above-mentioned embodiments and preferred embodiments, and will not be described again. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware, or a combination of software and hardware is also possible and contemplated.

[0058] The present application provides a resource determining device applied to a first node side, comprising: a first determining module, configured to determine the availability of a first type of resource of one or more time slots through an agreed rule and / or through resource configuration signaling.

[0059] Optionally, the application further provides an indication device of resource, applied to a second node side, comprising: a second determining module, configured to determine the availability of the first type resource indicated by the first node through an agreement rule and / or by sending resource configuration signaling to the first node.

[0060] It should be noted that the above modules can be realized by software or hardware, and for the latter, the following implementation manners can be used, but are not limited thereto: the above modules are located in the same processor; or the above modules are located in different processors in any combination.

[0061] The application will be illustrated below in combination with optional embodiments of the application.

[0062] Optional embodiment 1:

[0063] As shown in Figure 2 , the time domain resource attribute of the DU is divided into H (Hard), S (Soft) and NA (Not Available).

[0064] The parent node determines the slot positions of the Soft symbols in the DU resource of the child node according to the resource configuration of the child DU, as shown in Figure 2 , the slots marked as J, J+1, J+2, K, K+1, K+2 are the slots containing Soft symbols, and these slots do not require to be continuous in time domain.

[0065] In order to indicate the availability of different symbols in a slot, the protocol can agree on some availability patterns in a slot, as shown in Table 1, each item in the table defines an availability pattern in a slot.

[0066] Availability Index AI Availability Pattern 0 [1 1 1 1 1 1 1 1 1 1 1 1 1 1] 1 [0 1 1 1 1 1 1 1 1 1 1 1 1 1] 2 [0 0 1 1 1 1 1 1 1 1 1 1 1 1] 3 [0 0 0 1 1 1 1 1 1 1 1 1 1 1] 4 [0 0 0 0 1 1 1 1 1 1 1 1 1 1] 5 [0 0 0 0 0 1 1 1 1 1 1 1 1 1] 6 [0 0 0 0 0 0 1 1 1 1 1 1 1 1] 7 [1 0 1 0 1 0 1 0 1 0 1 0 1 0] ... ...

[0067] Table 1

[0068] Table 1 is an availability pattern of 14 OFDM symbols in a slot taking normal CP as an example.

[0069] Each index in Table 1 corresponds to the availability of symbols in a slot, where 1 means available, and the indication of availability works only for Soft symbols when the DU resource of a slot is not all Soft symbols. For example, if the first 4 symbols of a slot of 14 symbols are NA, and the last 10 symbols are Soft, and the available index (AI) of this slot is 2, the corresponding availability pattern is [0 0 1 1 1 1 1 1 1 1 1 1 1], which means the last 10 symbols are available, not the last 12 symbols.

[0070] One or more entries in Table 1 constitute the availability indication of Soft resources of one or several slots, which corresponds to one combination. By configuring multiple combinations to indicate multiple combinations of availability of Soft resources of several slots, the parent node configures multiple availability indications of Soft resources of several slots by high layer signaling, each combination is distinguished by a unique combination ID, and different combinations can contain different numbers of slots.

[0071] It is agreed that the availability of Soft resources indicated by the parent node applies to the slot carrying the dynamic signaling of Soft resource availability as the starting point, and the first slot containing Soft symbols.

[0072] As shown in Figure 2 , the dynamic signaling of Soft resource availability is carried on the slot marked as A. However, the slot marked as A does not contain Soft symbols. The slot containing Soft symbols closest to A as the starting point (including A) is J, and the parent node sends the dynamic signaling of Soft resource availability to the child node, which contains the unique combination ID described above. The combination ID corresponds to the availability pattern of one or several slots. For example, the combination ID combinationID1 corresponds to the Soft resource availability combination [0 1 2 3], which means that the Soft resource availability pattern of the first slot containing Soft symbols (numbered J) starting from A is [1 1 1 1 1 1 1 1 1 1 1 1 1 1], i.e. the Soft symbols on the slot numbered J are all available.

[0073] Figure 2The placement of the Hard and Soft resources in the table is only an example and does not limit the present application.

[0074] The availability of the Soft resources corresponding to the indexes in Table 1 is only an example and does not exclude other index combinations and different availability patterns, and does not limit the present application.

[0075] The dynamic signaling refers to physical layer signaling, such as transmission on a physical downlink control channel, a physical broadcast channel, or a physical feedback channel.

[0076] Optional implementation 2:

[0077] As shown in Table 1, the child node learns the availability pattern in each time slot corresponding to each availability index (AI) through protocol agreement.

[0078] The child node receives one or more combinations of Soft resource availability of a slot configured by the parent node through high layer signaling, wherein each combination corresponds to a combination ID.

[0079] The child node receives dynamic signaling indicating the combination of Soft resource availability in slot k, and according to the agreement rule, if slot k contains Soft symbols, the first slot corresponding to the Soft resource availability indication is slot k; if slot k does not contain Soft symbols, the slot number of the slot closest to slot k containing Soft symbols is slot k+n, then the first slot corresponding to the Soft resource availability indication is slot k+n.

[0080] For example, the child IAB receives the indication of the Soft resource availability of 4 slots in slot k, and the indexes of the availability patterns corresponding to the 4 slots are [0 1 2 3] respectively, the child IAB determines that slot k does not contain Soft symbols according to the resource configuration of the DU, and the child IAB determines that the 4 slots closest to slot k containing Soft symbols are slot k+n1, slot k+n2, slot k+n3, and slot k+n4 respectively, then the child IAB judges that the availability of the slot symbols of slot k+n1 is that all soft symbols are available, the availability of the slot symbols of slot k+n2 is that symbol 1-symbol 13 are available, and the rest is omitted.

[0081] In the above example, for slot k+n1, all the Soft symbols within the slot are available. But if only part of the symbols in slot k+n1 are Soft resources, the availability indication only applies to the Soft symbols. For example, if symbols 0~6 in slot k+n1 are Soft symbols, the actual result is that symbols 0~6 are available resources, i.e., the child DU can use these resources for resource scheduling of the next level node and terminal.

[0082] If the Soft DL resources of the DU are indicated as available, the DU can use these resources for downlink scheduling of the next level node and terminal. If the Soft UL resources of the DU are indicated as available, the DU can use these resources for uplink scheduling of the next level node and terminal.

[0083] The Soft resource availability corresponding to the index of Table 1 is only an example, and other index numbers and different availability patterns can be combined, without limiting the invention.

[0084] Optional implementation 3

[0085] As in the above optional implementation 1, a Soft resource availability pattern within some slots as shown in Table 1 is agreed through a protocol, and the parent node configures one or more groups of Soft resource availability combinations of a plurality of consecutive slots through high layer signaling, each combination corresponds to an availability pattern combination of one slot or a plurality of consecutive slots, each combination corresponds to a unique combination ID, and the number of slots corresponding to different combinations does not have to be the same.

[0086] The unique combination ID is for the child node, i.e., when the parent node configures a plurality of consecutive slot Soft resource availability combinations for child node 1 through high layer signaling, these combination IDs are unique for child node 1.

[0087] The indication method of this embodiment is different from that of embodiment 1 in that the availability indication includes Soft resource availability indication of a plurality of consecutive slots in time domain regardless of whether the slot includes Soft symbols.

[0088] As Figure 3As shown, the parent node sends dynamic signaling to the child node in slot A indicating the availability of soft resources in a number of consecutive slots in time domain, the dynamic signaling contains at least a combination ID indicating the availability combination of the number of consecutive slots.

[0089] The soft resource availability is effective in slot A by agreement, in the embodiment, if slot A does not contain soft symbols, the soft availability of the corresponding slot A is invalid regardless of the pattern, the indication of the notified soft availability is invalid.

[0090] Alternatively, the soft resource availability is effective in the slot containing soft symbols closest to slot A, corresponding to the slot J. Figure 3

[0091] Optional implementation 4

[0092] As shown in Table 1, by agreement, the child node knows the availability pattern in each time slot corresponding to each availability index (AI).

[0093] The child node receives the soft resource availability combination of one or a number of consecutive slots configured by the parent node through high layer signaling. Each combination corresponds to a combination ID.

[0094] The child node receives the dynamic signaling indicating the soft resource availability combination in slot k, if slot k contains soft symbols, the first slot corresponding to the soft resource availability indication is slot k; the child node receives the dynamic signaling indicating the soft resource availability in slot k, if slot k does not contain soft symbols, the slot containing soft symbols closest to slot k is slot k+n, then the first slot corresponding to the soft resource availability indication is slot k+n.

[0095] Alternatively, the child node receives the dynamic signaling indicating the soft resource availability in slot k, then the first slot corresponding to the soft resource availability indication is slot k.

[0096] ​The child node identifies the Soft resource availability pattern of several slots according to the combination ID of the received dynamic signaling indication, and judges the first slot corresponding to the Soft resource availability indication as the starting point of the Soft resource availability of the continuous slots according to the combination ID.

[0097] When there is no Soft symbol in a slot or the Soft symbol in a slot is inconsistent with the Soft resource availability pattern in the slot, the Soft resource availability pattern is only effective for the Soft symbol in the slot; or when there is no Soft symbol in a slot or the Soft symbol in a slot is inconsistent with the Soft resource availability pattern in the slot, for example, the Soft resource availability pattern indicates that all symbols (symbol 0-symbol 13) of a slot are available, and the DU resource configuration of the slot is only symbol 2-symbols 13 for Soft, it is considered that the Soft resource availability pattern of the slot is invalid, and it is determined that the Soft symbol of the slot is not indicated as available.

[0098] Optional implementation 5

[0099] By agreement of a protocol, the Soft resource availability pattern in some slots as shown in Table 2 is defined, and the indication manner of the embodiment is different from that of the optional implementation 3, in that Table 2 introduces an index not defined for the Soft resource availability pattern in the slot, which is called Soft resource undefined index, corresponding to index 255 in Table 2.

[0100]

[0101]

[0102] Table 2

[0103] Table 3 defines the availability pattern of 14 symbols in a slot under NCP (Normal Cyclic Prefix) configuration. Wherein 1 represents that the corresponding Soft symbol is available, and 0 represents that the corresponding Soft symbol is unavailable.

[0104] The parent node configures one or more groups of soft resource availability combinations of a number of consecutive slots through high layer signaling, each combination corresponds to a slot or a combination of availability patterns of multiple consecutive slots, each combination corresponds to a unique combination ID, and the number of slots corresponding to different combinations does not have to be the same. When the AI corresponding to a slot is not defined by the index of soft resource, it means that the parent node does not indicate the soft resource of this slot.

[0105] The unique combination ID is for the child node, that is, when the parent node configures a number of consecutive slot soft resource availability combinations for child node 1 through high layer signaling, these combination IDs are unique for child node 1. The combination ID informs child node 1 of the availability pattern of a number of consecutive slots, and if the parent node does not indicate the availability of any soft symbol of a slot, the AI corresponding to this slot in the combination pattern is set to the index of soft resource undefined.

[0106] Optional implementation 6

[0107] The embodiment of the present application is different from optional implementation 4 in that the index of soft resource availability pattern in a slot is not defined in table 2, which is called the index of soft resource undefined, and corresponds to index 255 in table 2.

[0108] The child node receives one or more groups of soft resource availability combinations of a number of consecutive slots configured by the parent node through high layer signaling. Each combination corresponds to a combination ID.

[0109] The child node receives dynamic signaling indicating soft resource availability combination in slot k, and if slot k contains soft symbols, the first slot corresponding to the soft resource availability indication is slot k; the child node receives dynamic signaling indicating soft resource availability in slot k, and if slot k does not contain soft symbols, the slot number containing soft symbols closest to slot k is slot k+n, then the first slot corresponding to the soft resource availability indication is slot k+n.

[0110] Or child node receives dynamic signaling indicating Soft resource availability in slot k, then the first slot corresponding to the Soft resource availability combination is slot k.

[0111] Child node identifies the Soft resource availability pattern of several slots according to the combination ID indicated by the received dynamic signaling, and the child node determines that the first slot corresponding to the Soft resource availability indication is the starting slot of the continuous several slots.

[0112] When there is no Soft symbol in a slot or the Soft symbol in a slot is inconsistent with the Soft resource availability pattern in the slot, the Soft resource availability pattern only takes effect for the Soft symbol in the slot; or when there is no Soft symbol in a slot or the Soft symbol in a slot is inconsistent with the Soft resource availability pattern in the slot, for example, the Soft resource availability pattern indicates that all symbols (symbol 0~symbol 13) of a slot are available, while the DU resource configuration of this slot only has symbol 2~symbols 13 as Soft, it is considered that the Soft resource availability pattern of this slot is invalid, and it is determined that the Soft symbol of the slot is not indicated as available.

[0113] When the child node identifies the resource availability of several slots according to the combination ID indicated by the received dynamic signaling, the corresponding slot of a slot is indicated as Soft resource undefined index, then the child node considers that the Soft resource of this slot is not indicated as available.

[0114] Optional implementation 7

[0115] Based on one of the above optional implementation 1 to optional implementation 7, the parent node and the child node can further agree that the resource availability of several slots indicated by the parent node through dynamic signaling repeatedly takes effect, for example, the parent node agrees two availability combination patterns through high layer signaling.

[0116] Combination 1 is continuous 5 slots, and the slot Soft resource availability index (AI) of these continuous or discontinuous slots is respectively [1, 2, 3, 4, 5] in table 2. The combination ID corresponding to the index is 1;

[0117] Combination 2 is two consecutive slots, and the slot-wise soft resource availability indices (AIs) of these consecutive or non-consecutive slots are [2, 4] respectively in Table 2. The corresponding combination ID of the combination 2 is 2.

[0118] If the slot corresponding to the combination ID is consecutive slots, the parent node indicates the combination ID of the soft resource availability of the child node on slot k through dynamic signaling, which means that the soft resource availability indices (AIs) of the five consecutive slots starting from slot k are [0, 1, 2, 3, 4]. According to the predetermined relationship in Table 1, the soft resource availability index (AI) of slot k is 1, and the availability pattern corresponding to the index is [1 1 1 1 1 1 1 1 1 1 1 1 1 1], that is, all the soft resources of slot k are available resources. The soft resource availability index (AI) of slot k+1 is 2, and the availability pattern corresponding to the index is [0 1 1 1 1 1 1 1 1 1 1 1 1], that is, the soft resources of symbol 1 to symbol 13 of slot k+1 are available resources, where the symbol number starts from 0.

[0119] If the parent node does not issue new dynamic signaling indication on slot k+6, the combination ID issued by slot k will continue to work according to the predetermined relationship. That is, the soft resource availability indices (AIs) of slot k+6 and slot k are the same, the soft resource availability indices (AIs) of slot k+7 and slot k+1 are the same, and so on. When the parent node is ready to update the DU configuration of the child node, the parent node can send new dynamic signaling to indicate a new combination ID, for example, send dynamic signaling containing combination ID 2 on slot k+6. Then the parent node informs the child node to use the slot-wise soft resource availability indices (AIs) of the two consecutive slots indicated by combination ID 2 on slot k+6, which are 2 and 4 respectively. That is, the soft resource availability pattern of slot k+6 is [0 0 1 1 1 1 1 1 1 1 1 1 1 1], and the soft resource availability pattern of slot k+7 is [0 0 0 1 1 1 1 1 1 1 1 1 1].

[0120] The same applies to the case that the slot corresponding to the combination ID is discontinuous slots. For example, the configuration of one period of DU resource of child node is [H S H S H S H S], where H represents hard, S represents Soft. When the parent node sends dynamic signaling indicating the combination ID is 2 in slot k, it indicates that the slot k+1, slot k+3 slot Soft resource availability index (AI) is 2 and 4 respectively, because slot k and slot k+2 do not contain Soft symbols. When the parent node wants to repeat the Soft resource availability combination of the subsequent slot, the parent node does not send new dynamic signaling. In this way, the slot k+7 and slot k+9 slot Soft resource availability index (AI) is 2 and 4 respectively.

[0121] Further, a field for indicating whether the combination ID repeats the effect can be introduced, for example, as shown in Table 3;

[0122] Availability Index AI Availability Pattern 0 [1 1 1 1 1 1 1 1 1 1 1 1 1 1] 1 [0 1 1 1 1 1 1 1 1 1 1 1 1 1] 2 [0 0 1 1 1 1 1 1 1 1 1 1 1 1] 3 [0 0 0 1 1 1 1 1 1 1 1 1 1 1] 4 [0 0 0 0 1 1 1 1 1 1 1 1 1 1] 5 [0 0 0 0 0 1 1 1 1 1 1 1 1 1] 6 [0 0 0 0 0 0 1 1 1 1 1 1 1 1] ... ... 255 Repeat

[0123] Table 3

[0124] The meaning of the slot Soft resource availability index (AI) of 255 agreed by the parent node and the child node tells the child node that the combination ID of this dynamic signaling will repeat the effect until a new dynamic signaling is sent.

[0125] For the child node, according to one of the embodiments 1 to 7, the child node receives the slot Soft resource availability combination of several continuous or discontinuous slots corresponding to different combination IDs configured by the parent node through high layer signaling.

[0126] When the child node receives the combination ID from the parent node indicating the availability of soft resources in several slots, for example, the combination ID 1 corresponds to the availability of soft resources in slots [1, 2, 3, 4, 5, 255] in the slots of 5 consecutive slots, the child node understands the pattern of soft resources availability in slot k as [0 1 1 1 1 1 1 1 1 1 1 1 1 1], and so on, the pattern of soft resources availability in slot k+4 is [0 0 0 0 1 1 1 1 1 1 1 1 1]. The last index 255 indicates that this dynamic signaling will be periodically effective unless a new dynamic signaling containing the combination ID is received. For example, when the child node does not receive the combination ID indicating the availability of soft resources in several slots in slot k+5, the child node will repeat the previously received combination ID for the subsequent slots, for example, the pattern of soft resources availability in slot k+6 is [0 1 1 1 1 1 1 1 1 1 1 1 1 1], and so on. When the child node receives a new combination ID, the child node understands the availability of soft resources in the current and subsequent slots according to the new combination ID.

[0127] This scheme is also applicable to the indication of the availability of soft resources in non-consecutive slots, for example: the configuration of the slots in one period of the DU resources of the child node is [H S H S H S H S], where H represents hard and S represents soft. When the child node receives the dynamic signaling indicating the combination ID 2 in slot k, the child node understands that the availability of soft resources in slots k+1 and k+3 is respectively 2 and 4. When the child node does not receive a new combination ID, the child node determines that the soft symbols in slots k+5 and k+7 are available, and so on.

[0128] In order to prevent the child node from missing the dynamic signaling and causing inconsistent understanding of the soft resources in a certain slot, it can be agreed that when the dynamic signaling for indicating the combination ID appears again after the repeated action field, the timing of the appearance of the dynamic signaling for indicating the combination ID is determined. For example, within the duration T1 after receiving the dynamic signaling for indicating the combination ID, a new dynamic signaling is not expected to be received. Wherein T1 can be a protocol agreed time or a parameter configured by a higher layer, and the child node understands the time configured by the parent node through receiving the signaling of the higher layer.

[0129] The index 255 indicates that the combination ID indicated by the dynamic signaling this time only works for one example, and the actual agreed table can also select different values, and the specific value does not limit the present application.

[0130] The DU resource H / S / NA period and the combination ID indicated by the dynamic signaling in the example of the present optional embodiment correspond to different time durations, and in actual process, the two can be the same.

[0131] Optional implementation 8

[0132] The slot in table 4 is described as the slot in the soft resource availability pattern, each of which corresponds to a slot in the direction indicated by the soft symbol availability pattern.

[0133]

[0134] Table 4

[0135] For example, the index 0 indicates that the uplink, downlink and flexible symbols in a slot are all unavailable, the index 1 indicates that the uplink soft symbols in a slot are available, and the downlink and flexible symbols are unavailable.

[0136] A plurality of slot soft symbol availability combinations are configured by high layer signaling, and each combination is a unique ID for a child node.

[0137] The parent node indicates the combination ID by dynamic signaling, and the index value indicates the availability of a series of slots containing soft symbols.

[0138] The high layer signaling defines a series of soft resource availability combinations of a plurality of slots containing soft symbols, and the number of slots contained in each combination is not required to be equal. For example, the first combination includes N1=4 slots, and the slot direction indicates the availability of soft symbols in the slot as [1 2 3 4], and the corresponding combination ID is 1; the second combination includes N2=4 slots, and the slot direction indicates the availability of soft symbols in the slot as [2 4 2 4], and the corresponding combination ID is 2.

[0139] The parent node transmits DCI indicating availability of soft resources on slot n, the combination ID value indicated by the DCI is 1, and the availability pattern of the four slots containing soft symbols in the transmission direction is [1 2 3 4].

[0140] There is no constraint relationship between the values of N1 and N2. In the embodiment, the number of slots corresponding to the two combination IDs is the same, and in actual application, the number of slots corresponding to the two combination IDs is not necessarily equal. In the embodiment, the number of slots corresponding to different combination IDs is equal, which does not limit the invention content.

[0141] Optional implementation 9

[0142] The child node receives DU resource configuration from a center unit (CU), and the DU resource properties of the child node from slot n to slot n+4 are as shown in Table 5:

[0143]

[0144] Table 5

[0145] In the table, HD represents hard DL, SD represents soft DL, HF represents hard flexible, SF represents soft flexible, HU represents hard UL, SU represents soft UL, and NA represents not available.

[0146] The child node receives the validity indication of the soft resource, which only applies to the resources with soft properties, such as soft DL, soft flexible, and soft UL.

[0147] The slot soft resource availability pattern described in Table 4 is agreed, and each index corresponds to a slot availability pattern indicating soft symbols in the direction.

[0148] For example, index 0 indicates that the uplink, downlink, and flexible symbols in a slot are all unavailable, index 1 indicates that the uplink soft symbols in a slot are available, and the downlink and flexible symbols are unavailable, and so on.

[0149] The child node receives high-level signaling configuration and learns the availability combination of soft symbols in a number of slots, and each availability combination corresponds to an ID, as shown in Figure 4 .

[0150] For example, the first combination includes N1=4 slots, and the availability of soft symbols in the slots is [1 2 3 4] in the direction of transmission, and the corresponding combination ID is 1; the second combination includes N2=4 slots, and the availability of soft symbols in the slots is [2 4 2 4] in the direction of transmission, and the corresponding combination ID is 2.

[0151] The child node receives the value 1 of the combination ID sent by the parent node on the slot n, and determines that the availability pattern of the soft resources of the four consecutive slots is [1 2 3 4] in the direction of transmission.

[0152] The child node understands the availability of the soft resources as follows:

[0153] The soft UL symbols of the slot n are available;

[0154] The soft flexible symbols of the slot n+1 are available;

[0155] All soft symbols of the slot n+2 are unavailable, because there is no soft resource in the slot n+2;

[0156] The soft DL symbols of the slot n+3 are available, and the rest of the soft symbols are unavailable.

[0157] The child node receives the value 1 of the combination ID sent by the parent node on the slot n, and determines that the availability pattern of the soft resources of the four slots containing soft symbols is [1 2 3 4] in the direction of transmission.

[0158] Another understanding of the child node for the availability of the soft resources is as follows:

[0159] The soft UL symbols of the slot n are available, and the rest of the soft symbols are unavailable;

[0160] The soft flexible symbols of the slot n+1 are available, and the rest of the soft symbols are unavailable;

[0161] All Soft UL symbols and Soft Flexible symbols in slot n+3 are available, and the rest of the Soft symbols are unavailable.

[0162] Soft DL symbols in slot n+4 are available, and the rest of the Soft symbols are unavailable.

[0163] Optional implementation 10

[0164] Figure 5 The correspondence between NCP and ECP (Extended Cyclic Prefix) OFDM symbols is given as shown in Table 1 to Table 3, one ECP OFDM symbol and two NCP OFDM symbols will overlap, the slot inner Soft symbols availability agreed in one of Table 1 to Table 3 is for the corresponding symbols of NCP slot. To support the indication of slot inner Soft symbols availability for ECP, it can be considered to define new slot inner Soft symbols availability for ECP, for example, as shown in Table 6: Figure 5

[0165]

[0166] Table 6

[0167] When in the slot configuration of ECP, then the parent node and the child node understand the availability of each availability index AI and the slot inner Soft symbols according to the slot inner Soft symbols availability pattern corresponding to the ECP configuration.

[0168] The parent node configures one or more combination IDs through high layer signaling, and each combination ID corresponds to the Soft symbol availability pattern of several slots.

[0169] The DU resource configuration of the child node from slot n to slot n+4 is shown in Table 7;

[0170]

[0171] Table 7

[0172] ​For example, when the child node works in the configuration of ECP, the child node receives the combination ID 1 sent by the parent node on slot n, which indicates the availability of Soft resources of several slots, corresponding to the slot-internal Soft resource availability index (AI) of the consecutive 5 slots [0, 1, 2, 3, 4] respectively, then the child node understands that the Soft resource availability pattern of slot n is [0 1 1 1 1 1 1 1 1 1 1 1], and so on, the Soft resource availability pattern of slot k+4 is [0 0 0 0 1 1 1 1 1 1 1 1].

[0173] Or the availability indication of the Soft symbols in the ECP configuration shares the same slot-internal Soft symbol availability pattern with the NCP, and the availability of the ECP symbol is determined based on one of the following criteria. Here, the slot-internal availability pattern agreed in Table 8 is adopted.

[0174]

[0175]

[0176] Table 8

[0177] When both of the two NCP symbols overlapping with the ECP are available, then the corresponding ECP Soft symbol is available. When not all of the two NCP symbols overlapping with the ECP are available, then the corresponding ECP Soft symbol cannot be considered to be explicitly indicated as available;

[0178] When the NCP symbol overlapping with the ECP for a longer region is indicated as available, then the corresponding ECP Soft symbol is available;

[0179] The availability pattern of the ECP Soft symbol only refers to the availability of the first nSymbSlotECP symbols in the availability pattern of the NCP Soft symbol, where nSymbSlotECP is the number of symbols corresponding to one slot in the configuration;

[0180] When one of the two NCP symbols overlapping with the ECP is indicated as available, then the corresponding ECP Soft symbol is available;

[0181] For criterion 1), all Soft symbols of slot n are available, since the NCP Soft symbols overlapping with the ECP are all available, the first symbol (numbered 0) of slot n+1 is not indicated as available, since the first NCP symbol it overlaps with is not indicated as available, the rest of the Soft symbols are all indicated as available. The Soft symbol availability of other slots follows by analogy;

[0182] For criterion 2), all Soft symbols of slot n are available, since the NCP Soft symbols overlapping with the ECP are all available, the first symbol (numbered 0) of slot n+1 is not indicated as available, since the longer NCP symbol (numbered 0) it overlaps with is not indicated as available, the rest of the Soft symbols are all indicated as available. The Soft symbol availability of other slots follows by analogy;

[0183] For criterion 3), all Soft symbols of slot n are available, since the first nSymbSlotECP NCP Soft symbols are all available, the first symbol (numbered 0) of slot n+1 is not indicated as available, since the first NCP symbol (numbered 0) of the first nSymbSlotECP is not indicated as available, the rest of the Soft symbols are all indicated as available. The Soft symbol availability of other slots follows by analogy;

[0184] For criterion 4), all Soft symbols of slot n are available, since the first nSymbSlotECP NCP Soft symbols are all available, the first symbol (numbered 0) of slot n+1 is available, since the NCP symbol (numbered 0) it overlaps with is available, the rest of the Soft symbols are all indicated as available. The Soft symbol availability of other slots follows by analogy.

[0185] Optional implementation 10

[0186] Similar to optional implementation 2 or optional implementation 4, the difference is that the child node does not receive the dynamic signaling containing the combined ID sent by the parent node, then the child node considers that all Soft symbols are not indicated as available.

[0187] Alternatively, the child node receives dynamic signaling indicating the combination ID at slot n, the dynamic signaling indicates the slot scope of slot A to slot A+scope_IA, but no further dynamic signaling is received after slot A+scope_IA, then the child node determines that the Soft symbols of the subsequent slots are not indicated as available, where scope_IA is the slot span of the availability indicated by the combination ID in the dynamic signaling.

[0188] Alternatively, based on one of the above embodiments 1 to 7, the parent node and the child node can further agree that the resource availability of the slots indicated by the dynamic signaling of the parent node repeats, for example, the parent node agrees two availability combination patterns by high layer signaling.

[0189] Combination 1 is 5 consecutive slots, the slot-wise Soft resource availability index (AI) of these consecutive or non-consecutive slots are [1, 2, 3, 4, 5] respectively, the corresponding combination ID is 1;

[0190] Combination 2 is 2 consecutive slots, the slot-wise Soft resource availability index (AI) of these consecutive or non-consecutive slots are [2, 4] respectively, the corresponding combination ID is 2;

[0191] If the slots corresponding to the combination ID are consecutive slots, the parent node indicates the combination ID of the Soft resource availability for the child node by dynamic signaling at slot k, which means that the slot-wise Soft resource availability index (AI) of the 5 consecutive slots starting from slot k are [0, 1, 2, 3, 4], according to the agreement relationship in Table 1, the availability pattern corresponding to the Soft resource availability index (AI) of slot k is [1 1 1 1 1 1 1 1 1 1 1 1 1 1], that is, all the Soft resources of slot k are available resources, the availability pattern corresponding to the Soft resource availability index (AI) of slot k+1 is [0 1 1 11 1 1 1 1 1 1 1 1 1], that is, the Soft resources of symbol 1 to symbol 13 of slot k+1 are available resources, here the symbol number starts from 0.

[0192] If the parent node does not send new dynamic signaling indication in slot k+6, the combination ID sent in slot k will be repeated. That is, the soft resource availability index (AI) of slot k+6 and slot k are the same, the soft resource availability index (AI) of slot k+7 and slot k+1 are the same, and so on. When the parent node is ready to update the DU configuration of the child node, the parent node can send new dynamic signaling indication of new combination ID, for example, sending dynamic signaling containing combination ID 2 in slot k+6, then the parent node informs the child node to use the soft resource availability index (AI) of the two consecutive slots indicated by combination ID 2 in slot k+6, which are 2 and 4 respectively. That is, the soft resource availability pattern of slot k+6 is [0 0 1 1 1 1 1 1 1 1 1 1 1 1], and the soft resource availability pattern of slot k+7 is [0 0 00 1 1 1 1 1 1 1 1 1 1].

[0193] Optional implementation 11

[0194] The DU resource configured by the center unit (CU) for the first node contains a reference subcarrier spacing, and the first node identifies the boundaries of slots and orthogonal frequency division multiplexing symbols of the first type of resource according to the subcarrier spacing of the DU resource configured for the first node.

[0195] When the DU resource configured by the center unit (CU) for the first node does not contain a reference subcarrier spacing, the first node identifies the boundaries of slots and orthogonal frequency division multiplexing symbols of the first type of resource according to the subcarrier spacing of the MT of the first node, or according to the reference subcarrier spacing configured by the MT of the first node for uplink and downlink. When the first node has multiple parent nodes, the availability of the first type of resource indicated by the dynamic signaling of each parent node is identified according to the subcarrier spacing configured by the parent node. Alternatively, the reference subcarrier spacing is contained in the availability configuration of the first type of resource.

[0196] Optional implementation 12

[0197] The center unit (CU) configures the DU resource for the first node through signaling, wherein the resource attribute is divided into Hard, Soft and NA, and the resource with Hard and Soft attribute can be further divided into Hard UL, Hard Flexible, Hard DL, Soft UL, Soft Flexible and Soft DL according to the direction. The DU resource type configured by the CU for the second node includes 7 resource types, which are Hard UL, Hard Flexible, Hard DL, Soft UL, Soft Flexible, Soft DL and NA, wherein the resource with Soft attribute corresponds to the first type resource of the embodiment.

[0198] The availability of the first type resource needs to be indicated through the parent node, i.e. Figure 6 The second node shown in the figure indicates the availability of the first type resource through signaling.

[0199] When the resource with Soft attribute is further indicated as available, the first node can use these resources for transmission scheduling of its child nodes and terminals.

[0200] Further, the transmission scheduling of the child nodes and terminals is undertaken by the distributed unit (DU) of the first node, and one DU can correspond to one or more cells, such as Figure 6 As shown in the figure, one DU corresponds to 3 cells, each of which serves terminals or child nodes. Cell ID_1 serves child nodes and terminals, cell ID_2 serves terminals, and cell ID_3 serves child nodes and terminals.

[0201] One indication mode of the availability of the first type resource is that the first node uniformly indicates the availability of the first type resource for the second node. Whether it is cell ID_1 or cell ID_2, the understanding of the availability is the same.

[0202] The signaling format is as follows:

[0203]

[0204] Among them,

[0205] sai-RNTI: RNTI used to identify the control signaling carrying the first type resource availability indication;

[0206] dci-PayloadSize: control signaling payload carrying the first type resource availability indication;

[0207] SoftAvailabilityCombinations: one or more first type resource availability combinations, each combination is a first type resource availability for one time slot or multiple time slots;

[0208] SoftAvailabilityCombination: first type resource availability combination

[0209] softAvailabilityCombinationId: first type resource availability combination index

[0210] softAvailability: first type resource availability for one time slot or multiple time slots

[0211] Further, the configuration parameters can also carry a plurality of cells corresponding to the first node, i.e. the aforementioned SoftIndicator can add a field cellId, and configure a plurality of cell-specific time slot first type resource availabilities for each cell corresponding to the first node. Or, on the basis of the second node configuring a plurality of time slot type one availabilities, additionally configure a plurality of time slot first type resource availabilities for the cells corresponding to the first node.

[0212] The cellId in the signaling can be an optional field, and when the cellID is missing, the first type resource availability indication for the first node or the first type resource availability indication for the DU of the first node is applied.

[0213] When the first node is simultaneously configured with the availability indication of the corresponding cell and the availability indication of the corresponding first node, i.e. the DU, the first type resource availability of the corresponding cell is determined according to the cell-specific first type resource availability.

[0214] Further, the first type resource availability can be further configured for a specific link of a specific cell of the first node.

[0215] Table 9 gives the determination method of the first type resource availability:

[0216]

[0217]

[0218] Table 9

[0219] A in the column of "configuration" in Table 9 indicates that the first node is configured with node or DU specific first type resource availability combination; B indicates that the first node is configured with cell specific first type resource availability combination; C indicates that the first node is configured with first type resource availability combination of specific link. A+B indicates that the first node is configured with node or distributed unit specific first type resource availability and also configured with cell specific first type resource availability combination, and the other cases are similar.

[0220] A in the column of "node or DU resource availability" in Table 8 indicates that the first node's node or DU specific first type resource availability combination is determined according to node or DU specific first type resource availability combination; / B indicates that the first node's first type resource availability combination is not configured or determined according to cell specific first type resource availability combination; / C indicates that the first node's first type resource availability combination is not configured or determined according to first type resource availability combination of specific link, and the other cases are similar. For example, in the combination configuration numbered 2, the first node is not configured with node specific first type resource availability combination, and the first node is configured with first type resource availability combination of the cell associated with the first node, then the first node's resource availability is determined according to the cell's first type resource availability combination by convention, or it is determined that there is no first type resource availability combination for the first node by convention, such as Figure 6 The cell of cell ID_1 of the first node in the middle is configured with first type resource availability combination, but the first node is not configured with first type resource availability combination, then the first type resource availability combination of the first node is determined according to the first type resource availability combination corresponding to the cell of cell ID_1. When the first node is not configured with first type resource availability combination, but the corresponding cell ID_1 and cell ID_2 are respectively configured with first type resource availability combination, and the cell of cell ID_3 is not configured with first type resource availability combination, then the first type resource availability combination corresponding to the cell of cell ID is applied to the first type resource availability combination of the first node, or the first type resource availability of the cell configured with first type resource availability is applied to the cell which has the same configuration as the cell not configured with first type resource availability combination. For example, Figure 6If the first node is configured with the first type resource availability combination of cell ID 1 and cell ID 2, and the first node is not configured with the first type resource availability combination of cell ID 3, and the cells of cell ID 3 and cell ID 2 have the same frame parameter configuration, for example, the two cells have the same subcarrier spacing, the same CP configuration, the same duplex mode or the same or similar frame structure configuration, the same or close center frequency, the same or close bandwidth, then the first node applies the first type resource availability combination of cell ID 2 to the first type resource availability combination of cell ID 3.

[0221] In the column of "cell resource availability" in Table 9, A indicates that the first type resource availability combination of the corresponding cell of the first node is determined according to the first type resource availability combination of the node or DU; / C indicates that the first type resource availability combination of the corresponding cell of the first node is not configured or determined according to the first type resource availability combination of the specific link. For example, in the combination configuration numbered 3, the specific cell of the first node is not configured with the first type resource availability combination, and the first type resource availability combination of the cell is determined according to the first type resource availability combination of the first node.

[0222] In the column of "specific link resource availability" in Table 9, A indicates that the first type resource availability combination of the specific link of the first node is determined according to the first type resource availability combination of the node or DU. For example, in the combination configuration numbered 1, the first node is not configured with the first type resource availability combination of the specific link, and the specific link can be a terminal or a sub-node connected to the first node, such as Figure 6 In the combination configuration numbered 1, the first node is not configured with the first type resource availability combination of the specific link, and the specific link can be a terminal or a sub-node connected to the first node, such as

[0223] The first node receives control information containing availability combination ID, descrambles the control information according to the RNTI indicated in the SoftIndicator, and extracts the first type resource availability of the corresponding node or the corresponding DU or the corresponding cell or the corresponding link from the corresponding position of the control information according to the positionInDCI indicated in the SoftIndicator. When the first node receives the first type resource availability indication of the corresponding node and the first type resource availability indication of the corresponding cell at the same time, the availability of the first type resource is determined according to the first type resource availability indication of the corresponding cell. When the first node receives the first type resource availability indication of the corresponding node and the first type resource availability indication of the corresponding cell at the same time, and receives the first type resource availability indication of a certain link connected by the cell, the availability of the first type resource of the link is determined according to the first type resource availability indication of the link. That is, when the first type resource availability indication of two or more granularities is configured at the same time, the availability of the first type resource is determined according to the smaller granularity.

[0224] Optional implementation 13

[0225] According to the method of optional implementation 1, 3, 5, 7, and 8, the parent node indicating the first type resource or Soft resource availability to the child node can further indicate an offset of the validity of the resource availability.

[0226] The parent node additionally configures an offset for each combination of the first type resource availability combination of the child node, and the offset is the duration corresponding to one or more orthogonal frequency division multiplexing symbols. Alternatively, the offset is the duration corresponding to one or more time slots.

[0227] The configuration signaling is as follows:

[0228]

[0229]

[0230] The signaling format above configures an offset value for each combination, for example, the offset corresponding to the type one or Soft resource availability combination with the combination ID of 1 is 1, and the unit is time slot, so that the parent node indicates the child node to take effect after one time slot offset when receiving the dynamic signaling with the combination ID of 1.

[0231] Optionally, the offset field is moved from the SoftAvailabilityCombination to the SoftIndicator, and the parent node configures a common offset for all the combinations of the child node.

[0232] The parent node can also configure different offsets for the child node corresponding to different cells, and each cell has a same offset for the first type resource availability.

[0233] The parent node can also further configure a common offset for all the child node, and each cell corresponding to the child node takes the common offset.

[0234] The offset can also be notified by dynamic signaling, and the dynamic signaling notifies an index value indicating the first type resource or Soft resource availability combination of one or more time slots, and the dynamic signaling further carries an offset field to indicate that the child node takes effect after a certain time offset after receiving the indication signaling.

[0235] The time amount represented by the offset field in the dynamic signaling can also be a predefined time configured by the higher layer signaling, for example, the higher layer signaling agrees on 8 offset time amounts, and each offset time amount corresponds to an index value, and the offset field in the dynamic signaling indicates the specific offset time amount by indicating the index value.

[0236] The parent node can further indicate the duration of the resource availability taking effect when indicating the first type resource or Soft resource availability to the child node.

[0237] The parent node can further configure an available time for each combination of the first type resource availability combination of the child node, and the available time is the duration corresponding to one or more orthogonal frequency division multiplexing symbols. Alternatively, the available time is the duration corresponding to one or more time slots.

[0238] The available time can also be notified by dynamic signaling, and the dynamic signaling notifies an index value indicating the first type resource or Soft resource availability combination of one or more time slots, and the dynamic signaling further carries a duration field to indicate the duration of the child node taking effect after receiving the indication signaling.

[0239] The time represented by the effective time field in the dynamic signaling can also be a predefined time configured by high layer signaling, for example, the high layer signaling agrees on 8 offset time amounts, each offset time amount corresponds to an index value, and the offset amount field in the dynamic signaling indicates the specific offset time amount of the child node through the index value.

[0240] Optional implementation 14

[0241] As the method in optional implementation 2, 4, 6, 7, 9, the child node receives the offset indication in the first type resource or soft resource availability combination configured by the parent node.

[0242] The child node determines the type of one or more time slots to be resource or soft resource availability after receiving the offset amount of the first type resource or soft resource availability combination index indicated by the parent node.

[0243] For example, the child node receives the combination index 1 at slot k, the offset amount is one time slot, and the combination index 1 is continuous 2 slots. The soft resource availability index (AI) of these continuous or discontinuous slots is [2, 4, ] in table 2. When the indication method is continuous indication, the child node determines that the AI of slot k+1 is 2, that is, the first two orthogonal frequency division multiplexing symbols of slot k+1 are type one or soft type, and the availability of the orthogonal frequency division multiplexing symbols is unavailable. If the remaining orthogonal frequency division multiplexing symbols are type one or soft type, the availability of the child is available; the AI of slot k+2 is 4, that is, the first four orthogonal frequency division multiplexing symbols of slot k+2 are type one or soft type, and the availability of the orthogonal frequency division multiplexing symbols is unavailable. If the remaining orthogonal frequency division multiplexing symbols are type one or soft type, the availability of the child is available.

[0244] The available time can also be determined by receiving the dynamic signaling notification carrying the duration field to determine the duration of the child node after receiving the indication signaling.

[0245] The offset amount or duration represented by the effective time field in the dynamic signaling can also be a predefined time configured by high layer signaling, for example, the high layer signaling agrees on 8 offset time amounts or durations, each offset time amount or duration corresponds to an index value, and the child node determines the offset time amount or effective duration of the indication signaling by obtaining the index value of the offset amount or duration in the dynamic signaling.

[0246] The determination of the offset amount and / or duration includes the following methods:

[0247] determining the offset by the child node receiving the first type resource or soft resource availability combination;

[0248] or, the child node receiving the first type resource or soft resource availability combination corresponding to a specific cell to determine the offset;

[0249] or, determining the offset by the child node receiving dynamic signaling of the soft resource availability combination index.
