Detailed Description

In order to make the application object, technical scheme and beneficial effects of the present application more clear, the following description will explain the embodiments of the present application with reference to the accompanying drawings, and it should be noted that, without conflict, the embodiments of the present application and features in the embodiments can be arbitrarily combined with each other.

The current NR system has three frame structure configurations as follows:

1. semi-static Cell-specific frame structure configuration

2. Semi-static UE-specific frame structure configuration

3. Dynamic Group common frame structure configuration

The semi-static Cell-specific frame structure configuration is configured through tdd-UL-DL-ConfigurationCommmon signaling, the semi-static UE-specific frame structure configuration is configured through tdd-UL-DL-ConfigDedicated signaling, and the dynamic Group common frame structure configuration is namely a downlink control information format (Downlink Control Information, DCI format) 2_0, and an immediate-time format indication (Slot Format Indication, SFI).

For a semi-static Cell-specific frame structure, the Slot (Slot) configuration in the NR is configured in the tdd-UL-DL-ConfigurationCommmon signaling, which is Cell-specific, i.e., the Slot configuration received by all UEs camping on the serving Cell is the same. the tdd-UL-DL-ConfigurationCommmon signaling is contained in system information blocks (System Information Blocks, SIB) 1 and ReconfigurationWithSync, where the tdd-UL-DL-ConfigurationCommmon signaling content is as follows. Wherein the TDD-UL-DL-Pattern defines two patterns Pattern1 and Pattern2, wherein Pattern2 is optional and the DL-UL-TransmissionPeriodicity field defines a period of up to 10 ms. The frame structure shown in fig. 1 can be assembled under the double-period structure, the maximum length of each pattern is 10ms, and fig. 1 is a schematic configuration diagram of the double-period frame structure. The length of the slot format (solt format) in the current standard is 20ms at maximum, the number of slots is 640 at maximum, and the slot corresponds to 480kHz subcarrier spacing (Sub-CARRIER SPACE, SCS). The following maxNrofSlots field defines a maximum number of slots of 320 within a maximum 10ms period.

TDD-UL-DL-ConfigCommon

The following is a symbol (symbol) number and configuration signaling indication of the time slot.

maxNrofSymbols-1 INTEGER::＝13--Maximum index identifying a symbol within a slot(14symbols,indexed from 0..13)

maxNrofSlots INTEGER::＝320--Maximum number of slots in a 10ms period

maxNrofSlots-1 INTEGER::＝319--Maximum number of slots in a 10ms period minus 1

Table 1 number of OFDM symbols per slot, number of slots per radio frame, number of slots per subframe under normal cyclic prefix

Table 2 number of OFDM symbols per slot, number of slots per radio frame, number of slots per subframe under extended frame cyclic prefix

μ	Number of symbols in each slot	Number of slots in each radio frame	Number of slots in each subframe
				2	12	40	4

As is clear from the above description, a maximum period of 20ms is supported for the frame structure configured by tdd-UL-DL-ConfigurationCommmon signaling.

The semi-static UE-specific frame structure configuration is configured through tdd-UL-DL-ConfigDedicated signaling, the specific signaling content is shown below, wherein SlotIndex identifies a slot in a slot period configured in tdd-UL-DL-configurationCommon signaling, and it can be seen that the frame structure range of the tdd-UL-DL-ConifgDedicated signaling configuration does not exceed the tdd-UL-DL-configurationCommon period. tdd-UL-DL-SlotConfig is based on maxNrofSlots values, whereas maxNrofSlots corresponds to a maximum of 10ms. The UE-specific configuration can only reconfigure X slot/symbol of the Cell-specific configuration, as shown in fig. 2, fig. 2 is a schematic diagram of a flexible configuration frame structure, where D represents a downlink frame, U represents an uplink frame, and X represents a frame that can be flexibly configured. In addition, the TDD-UL-DL-ConfigDedicated signaling can only modify the frame structure for a maximum of 10ms, because TDD-UL-DL-SlotConfig is based on maxNrofSlots values, while maxNrofSlots corresponds to a maximum of 10ms, but cannot be modified for the dual slot pattern mode (20 ms period).

ASN1START

As is clear from the above description, the frame structure configured by using the tdd-UL-DL-ConfigDedicated signaling supports a maximum period of 10ms, and there is a problem of mismatch with the tdd-UL-DL-ConfigurationCommmon signaling, that is, no dual period configuration.

For the dynamic frame structure of the Group common signaling configuration, SFI is an optional function, if the UE needs to receive both the semi-static frame structure configuration and the dynamic frame structure configuration, the SFI makes sense on the "X" slot of the semi-static frame structure configuration, that is, the SFI can only reconfigure the X slot, as shown in fig. 2.

SlotFormatIndicator information element (information element) is used to configure the Group-Common-PDCCH that monitors SFI.

SlotFormatIndicator information element

SlotFormatCombinationsPerCellinformation element is used to configure an available slot format combination (SlotFormatCombinations) for one serving cell.

SlotFormatCombinationsPerCell information element

Each SlotFormatCombination corresponds to a combination identifier (combination id) and a group of Slot formats (Slot formats), wherein up to 512 slots (9 bits) can be configured in SlotFormatCombination, up to 256 slots can be configured in Slot formats, as shown in fig. 3, and fig. 3 is a Slot format table under a common cyclic prefix, and as can be seen, up to 256 frame structure configurations are provided.

maxNrofSlotFormatsPerCombination INTEGER::＝256

maxNrofSlotFormatCombinationsPerSet INTEGER::＝512--Maximum number of Slot Format Combinations in a SF-Set.

maxSFI-DCI-PayloadSize INTEGER::＝128--Max number payload of a DCI scrambled with SFI-RNTI

maxNrofAggregatedCellsPerCellGroup INTEGER::＝16

The SFI signaling format is shown in fig. 4, fig. 4 is a schematic diagram of the SFI signaling format, and as can be seen in fig. 4, the DCI format2-0 signaling includes N SFI indexes, sfi_index0 to sfi_ indexN, each SFI index is used to indicate a group solt format, for example, sfi_index0 indicates that a timeslot format with a combination id of 3 in Cell1 (Cell 1) is 255, and specific format contents can be known by querying the table shown in fig. 3. SFI_index1 indicates that the time slot format with the combination id of 0 in Cell2 (Cell 2) is 7, 2 and 1, a plurality of time slot formats can be circularly configured, and specific format contents can be obtained by querying a table shown in FIG. 3.

In addition, since the length of slot format configured in the Combination (Combination) must be greater than the listening period of the SFI in the current protocol, the frame structure in different periods can be indicated by the SFI sent in different periods, and assuming that AI/ML can predict the configuration of the frame structure for a longer time, the blind detection number of the SFI can be reduced, the number of slots formats in each Combination must be configured to be very large through a radio resource control (Radio Resource Control, RRC) message based on the existing standard, but the larger number of slots formats in each Combination means the larger number of combinations that can be combined. A problem with Grpup common signaling configured in this way is that the signaling overhead or blind test times may be increased when configured for long periods.

Fig. 5 is a flowchart of an enhanced frame structure configuration method according to an embodiment of the present application, where, as shown in fig. 5, the enhanced frame structure configuration method provided in the embodiment includes:

In step S510, enhanced frame structure length information is configured in the first signaling, the enhanced frame structure length information including information indicating a time domain length of the radio frame.

The enhanced frame structure configuration method provided by the embodiment is used for configuring the enhanced frame structure length for the UE, wherein the enhanced frame structure length is the time domain length of the more flexible wireless frame, and can provide a longer time domain length for the wireless frame. With the introduction of the AI/ML technology, the service prediction with longer time can be realized based on the AI/ML technology, so that a longer time domain length is configured for the wireless frame, and the service scheduling can be more flexible. The enhanced frame structure configuration method provided by the embodiment is applied to a base station, the base station configures enhanced frame structure length for the UE, and the enhanced frame structure length information is sent to the UE through signaling.

First, a base station configures enhanced frame structure length information in a first signaling, the enhanced frame structure length information including information for indicating a time domain length of a radio frame. The first signaling may be control signaling sent by any base station to the UE, or the first signaling is signaling information carried in other forms in data sent by the base station to the UE. The enhanced frame structure length information may be carried in different forms in the first signaling, for example, a new field is configured in the first signaling, or a new parameter value is configured in an existing field in the first signaling, or an additional dedicated area is set in the header of the first signaling, etc. The enhanced frame structure length information is used to indicate the time domain length of the radio frame, and as can be seen from the foregoing description, the frame structure length of the radio frame may be indicated in various forms such as pattern (pattern), time domain length, and slot format combination, so in this embodiment, the enhanced frame structure length, that is, the indication of the longer time domain length of the radio frame may be achieved by expanding the indication form of any of the above-mentioned radio frame structure lengths. In the following embodiments, various enhanced frame structure length indication methods will be described in detail. The enhanced frame structure length information is different from the information used for indicating the frame structure length in the current wireless communication system, and can indicate a wireless frame with longer time domain length, so that longer time domain service prediction can be supported.

The configuration of the enhanced frame structure length information in the first signaling may be triggered by the base station, i.e. to coordinate with long-period traffic prediction of the base station. The AI/ML may also be a UE side model, that is, UE side service operation prediction, and the UE may estimate a long-period slot format, then the UE will feedback the estimated long-period slot format to the base station, and after receiving the long-period slot format prediction information sent by the UE, the base station configures enhanced frame structure length information in the first signaling based on the information fed back by each UE.

Step S520, the first signaling is sent to the UE.

After the base station configures the enhanced frame structure length information in the first signaling, the base station can send the first signaling to the UE, and the UE receiving the first signaling can determine the time domain length of the radio frame according to the enhanced frame structure length information because the enhanced frame structure length information is configured in the first signaling. Because the enhanced frame structure length information is more flexible than the traditional wireless frame length indication in the 5G system and supports longer time domain length, when the communication system uses the AI/ML technology to conduct longer time service prediction, the wireless frame with longer time domain length can be used to match longer time domain service prediction results. Therefore, the enhanced frame structure configuration method provided by the embodiment provides support for service application of the mobile communication system in a longer time domain.

According to the enhanced frame structure configuration method provided by the embodiment, the enhanced frame structure length information is configured in the first signaling, wherein the enhanced frame structure length information comprises information for indicating the time domain length of the radio frame, and then the first signaling is sent to the UE, so that a more flexible strategy for configuring the time domain length of the radio frame is provided, the radio frame with longer time domain length can be supported, and flexible time domain length support of the radio frame can be provided for the service.

For the above three cases of NR frame structure configuration, the enhanced frame structure configuration method provided in the embodiments of the present application may be implemented by extending the signaling configured by these three NR frame structures, that is, the first signaling is a general signaling for configuring a semi-static cell dedicated frame structure, or the first signaling is a dedicated signaling for configuring a semi-static UE dedicated frame structure, or the first signaling is a general signaling for configuring a dynamic dedicated frame structure, and an enhanced frame structure length information field is newly added in the signaling, or a field for indicating a time domain length of a radio frame in the signaling is extended to the enhanced frame structure length information. Or the first signaling is newly added signaling dedicated to indicating enhanced frame structure length information. The method for expanding the signaling for configuring the current NR frame structure can be better compatible with the NR signaling of the previous version, and meanwhile, the signaling consumption of additional configuration is reduced.

The enhanced frame structure configuration method provided by the embodiment of the present application is described in detail below for the case that the first signaling is different signaling.

When the first signaling is general signaling for configuring a semi-static Cell-specific frame structure, the enhanced frame structure length information includes the number of patterns N in the extended radio frame, where N is greater than 2.

The general signaling used to configure the semi-static cell-specific frame structure may be, for example, the tdd-UL-DL-ConfigurationCommmon signaling described previously. In the foregoing general signaling for configuring a semi-static cell-specific frame structure, a configuration of at most 2 radio frame patterns (patterns) is supported, whereas in the embodiment of the present application, the number of patterns N in the extended radio frame is configured in the general signaling for configuring a semi-static cell-specific frame structure, where N is greater than 2, i.e. a number of patterns that can provide more than 2 radio frames, a frame structure indication under a greater radio frame length is supported, e.g. greater than 20ms. As long as additional radio frame pattern configurations are added as needed at the positions where the radio frame patterns were originally configured in the general signaling for configuring the semi-static cell-specific frame structure. Since the general signaling for configuring the semi-static cell-specific frame structure is for the configuration of the serving cell, all UEs within the serving cell will receive the signaling and learn the enhanced frame structure length information.

When the first signaling is dedicated signaling for configuring a semi-static UE-specific frame structure (semi-static UE-specific frame structure), the enhanced frame structure length information includes at least one of: the number of patterns M in the spread radio frame, the time domain length information of the radio frame, where M is greater than or equal to 2.

The dedicated signaling for configuring the semi-static UE-specific frame structure may be, for example, the tdd-UL-DL-ConfigDedicated signaling described previously. In the dedicated signaling for configuring the semi-static UE-specific frame structure, the enhanced frame structure length information may also be indicated in a manner of configuring the number of images in the radio frame, where the number of patterns in the extended radio frame is M, where M is greater than or equal to 2. Or the time domain length information of the radio frames is extended in the dedicated signaling for configuring the semi-static UE dedicated frame structure, specifically, the number of radio frames can be configured, the time occupied by one radio frame in the time domain is for example 10ms, the number P of radio frames can be configured, for example, when p=4, the reconfiguration of X time slots on the frame structure of 40ms in succession is allowed, as shown in fig. 6, fig. 6 is an extended frame structure configuration schematic diagram provided in the embodiment of the present application, where D represents a downlink frame, U represents an uplink frame, and X represents a flexibly configurable frame. Or in the dedicated signaling for configuring the semi-static UE-specific frame structure, the number of patterns M in the extended radio frame and the time domain length information of the radio frame may also be simultaneously configured.

Wherein the number of patterns in the extended radio frame is configured in a dedicated configuration or in a serving cell configuration, i.e. the number of patterns in the extended radio frame may be configured in a dedicated configuration for a UE, configured for only one specific UE; or the number of patterns in the extended radio frame may also be configured in the serving cell configuration, for all UEs within the serving cell.

Specific enhanced frame structure length information is schematically illustrated below using tdd-UL-DL-ConfigDedicated signaling as an example.

Firstly, a configurable P value is introduced by removing the radio frame boundary limit of 10ms for the configuration of TDD-UL-DL-SlotIndex, TDD-UL-DL-SlotIndex: =INTEGER (0..P. MaxNrofSlots-1).

Or adding a pattern (pattern) in TDD-UL-DL-ConfigDedicated signaling, and the number of patterns is configurable, and the signaling is dedicated signaling for UE, as follows:

Alternatively, patterns may be added to ServingCellConfig and the number of patterns configurable, this signaling being for the serving cell, as follows.

Since the dedicated signaling for configuring the semi-static UE-specific frame structure is configured for the UE, the enhanced frame structure may be configured separately for different UEs, which may perform the required traffic according to the time domain length of the radio frame indicated by the dedicated signaling configured for them.

When the first signaling is generic signaling for configuring a dynamic private frame structure (Group common frame structure), the enhanced frame structure length information includes a period or duration of an extended radio frame.

The general signaling for configuring the dynamic dedicated frame structure may be, for example, the aforementioned DCI format2_0, i.e., SFI. In general signaling for configuring a dynamic dedicated frame structure, indication information for indicating a period (periodicity) or a duration (duration) of a radio frame, which indicates a period of one radio frame or a duration of one radio frame, is newly added. The period or duration of the extended radio frame is located in the first signaling header dedicated area, that is, the header area is added on the basis of the original signaling, and the period or duration of the extended radio frame is carried in the header area, and some other public information can be also put in the newly added header area for notification. The period or duration of the extended radio frame located in the first signaling header dedicated area is used to indicate the period or duration of the slot format combination of one or more consecutive radio frames, i.e. the period or duration of the slot format combination of one radio frame may be indicated with the period or duration of the extended radio frame carried in the first signaling header dedicated area, or the period or duration of the slot format combination of a plurality of consecutive radio frames may be indicated with the period or duration of the extended radio frame carried in the first signaling header dedicated area, as can be seen from fig. 3, the slot format combination of one radio frame is determined according to its format number, and after increasing the period or duration of the extended radio frame, the slot format combination of a plurality of consecutive radio frames may be indicated, i.e. the slot format number of a plurality of consecutive radio frames is indicated. As shown in fig. 7, fig. 7 is a schematic diagram of formats of different DCI format2_0 signaling, and it can be seen from the figure that the original DCI format2_0 signaling includes N SFI indexes, where each SFI index from sfi_index0 to sfi_ indexN is used to indicate a set solt format, as shown in fig. 4. The extended DCI format2_0 signaling may be preceded by N consecutive SFI indexes by a header-specific area (Head) to indicate a period or duration of a radio frame indicated by the following consecutive N SFI indexes. Or the extended DCI format2_0 signaling may be preceded by a header-specific area (Head) for each of the N SFI indexes to indicate a period or duration of a radio frame indicated by the following 1 SFI index. Or the period or duration of the extended radio frame may be carried in the first signaling. The slot format combinations of the multiple radio frames are indicated, for example, by modifying the RRC configuration to add fields in the current SFI information, as follows:

In addition, the period or duration of the extended radio frame may be configuration information for the UE or configuration information for the cell, that is, may be configured for a specific UE or may be configured for a serving cell when the period or duration of the extended radio frame is configured. This uniform period may be used for all slotFormatCombination, for example, as shown in SlotFormatCombinationPerCell:

Further, for the case that the first signaling is generic signaling for configuring a dynamic dedicated frame structure, since the enhanced frame structure length information includes the period or duration of the extended radio frame, the period or duration can be increased for the radio frame, which breaks the limitation that the multiple slot format lengths in the existing slot combination must be greater than the SFI blind detection period, that is, a smaller slot format length can be configured to achieve a longer SFI indication. Specifically, the blind detection period of the first signaling is a larger value of the period or duration of the extended radio frame and the preset blind detection period of the first signaling. After the period or duration of the extended radio frame is configured, even if the SFI blind detection period is reached, blind detection monitoring on a Monitor Occalation (MO) period of the corresponding SFI within the period or duration can be omitted. Further, when the first SFI blind test period after the configured period or duration arrives, a new SFI is triggered, and the actual SFI blind test period is a larger value of the preset SFI blind test period and the period or duration of the extended radio frame. If no new SFI is detected in the first SFI blind detection period after the configured period or duration, the preset behavior is still configured according to the frame structure of the previous period, and the SFI detection can be performed by taking the period or duration of the extended radio frame and the smaller value in the preset SFI blind detection period as the new blind detection period of the SFI.

Fig. 8 is a flowchart of another enhanced frame structure configuration method according to an embodiment of the present application, as shown in fig. 8, where the enhanced frame structure configuration method provided by the present embodiment includes:

Step S810, detecting a first signaling sent by a base station, where enhanced frame structure length information is configured in the first signaling, where the enhanced frame structure length information includes information for indicating a time domain length of a radio frame.

The enhanced frame structure configuration method provided by the embodiment is used for data transmission by the UE according to the enhanced frame structure length configured by the base station, wherein the enhanced frame structure length is the time domain length of the more flexible wireless frame, and can provide a longer time domain length for the wireless frame. With the introduction of the AI/ML technology, the service prediction with longer time can be realized based on the AI/ML technology, so that a longer time domain length is configured for the wireless frame, and the service scheduling can be more flexible. The enhanced frame structure configuration method provided by the embodiment is applied to the UE, the UE acquires the signaling sent by the base station to acquire the length of the enhanced frame structure configured by the base station for the UE, and then data receiving or sending is carried out according to the length information of the enhanced frame structure.

First, the UE detects a first signaling sent by the base station, where enhanced frame structure length information is configured in the first signaling, where the enhanced frame structure length information includes information for indicating a time domain length of a radio frame. The enhanced frame structure length information is configured by the base station. The first signaling may be control signaling sent by any base station to the UE, or the first signaling is signaling information carried in other forms in data sent by the base station to the UE. The enhanced frame structure length information may be carried in different forms in the first signaling, for example, a new field is configured in the first signaling, or a new parameter value is configured in an existing field in the first signaling, or an additional dedicated area is set in the header of the first signaling, etc. The enhanced frame structure length information is used to indicate the time domain length of the radio frame, and as can be seen from the foregoing description, the frame structure length of the radio frame may be indicated in various forms such as pattern (pattern), time domain length, and slot format combination, so in this embodiment, the enhanced frame structure length, that is, the indication of the longer time domain length of the radio frame may be achieved by expanding the indication form of any of the above-mentioned radio frame structure lengths. In the foregoing embodiments, various enhanced frame structure length indication methods have been described in detail. The enhanced frame structure length information is different from the information used for indicating the frame structure length in the current wireless communication system, and can indicate a wireless frame with longer time domain length, so that longer time domain service prediction can be supported.

The configuration of the enhanced frame structure length information in the first signaling may be triggered by the base station, i.e. to coordinate with long-period traffic prediction of the base station. The AI/ML may also be a UE side model, that is, UE side service operation prediction, and the UE may estimate a long-period slot format, then the UE will feedback the estimated long-period slot format to the base station, and after receiving the long-period slot format prediction information sent by the UE, the base station configures enhanced frame structure length information in the first signaling based on the information fed back by each UE. Thus, before step S810, the following steps may be further included: predicting a long period time slot format; and sending the long period time slot format prediction information to the base station.

Step S820, performing data reception or data transmission according to the enhanced frame structure length information.

After the base station configures the enhanced frame structure length information in the first signaling, the base station can send the first signaling to the UE, and because the enhanced frame structure length information is configured in the first signaling, the UE receiving the first signaling can determine the time domain length of the radio frame according to the enhanced frame structure length information, and perform data reception or data transmission according to the enhanced frame structure length information. Because the enhanced frame structure length information is more flexible than the traditional wireless frame length indication in the 5G system and supports longer time domain length, when the communication system uses the AI/ML technology to conduct longer time service prediction, the wireless frame with longer time domain length can be used to match longer time domain service prediction results. Therefore, the enhanced frame structure configuration method provided by the embodiment provides support for service application of the mobile communication system in a longer time domain.

According to the enhanced frame structure configuration method provided by the embodiment, by detecting the first signaling sent by the base station, wherein the first signaling is configured with enhanced frame structure length information, the enhanced frame structure length information comprises information for indicating the time domain length of the wireless frame, and then data receiving or data sending is performed according to the enhanced frame structure length information, a more flexible wireless frame time domain length configuration strategy is provided, wireless frames with longer time domain lengths can be supported, and flexible wireless frame time domain length support can be provided for services.

In the same manner as in the embodiment shown in fig. 5, in the case that the first signaling is different signaling, the specific configuration manner of the first signaling is already described in detail in the foregoing embodiment, which is not described herein again.

Further, when the first signaling is a generic signaling for configuring a dynamic dedicated frame structure, after detecting the first signaling sent by the base station, the method further includes: and taking the larger value of the period or duration of the extended radio frame and the preset blind detection period of the first signaling as the blind detection period of the first signaling. After taking the larger value of the period or duration of the extended radio frame and the preset blind detection period of the first signaling as the blind detection period of the first signaling, the method further comprises the steps of: if the period or duration of the extended radio frame is taken as the blind detection period of the first signaling, and no new first signaling is detected in the first blind detection period, taking the smaller value of the period or duration of the extended radio frame and the preset blind detection period of the first signaling as the new blind detection period of the first signaling. Fig. 9 is a schematic diagram of a blind test period of the first signaling, as shown in fig. 9, taking the duration of the extended radio frame as an example, after the extended duration is carried in the first signaling, in the extended duration, the blind test SFI is stopped when the original SFI blind test period is ended and still in the extended duration, until the first SFI blind test period in the next extended duration is reached, and then the blind test SFI is performed.
