[0029] The embodiments of the present application are described below with reference to the accompanying drawings. Unless there is any conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other.

[0030] The NR system has the following three frame structure configurations:

[0031] 1. Semi-static Cell-specific frame structure configuration.

[0032] 2. Semi-static UE-specific frame structure configuration.

[0033] 3. Dynamic Group common frame structure configuration.

[0034] 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 the downlink control information format (Downlink Control Information, DCI format) 2_0, that is, the slot format indication (SFI).

[0035] For the semi-static Cell-specific frame structure, the time slot configuration in NR is configured in the tdd-UL-DL-ConfigurationCommmon signaling, which is cell-specific, that is, the slot configuration received by all UEs residing on the serving cell is the same. The tdd-UL-DL-ConfigurationCommmon signaling is contained in the System Information Blocks (SIB) 1 and ReconfigurationWithSync, where the content of the tdd-UL-DL-ConfigurationCommmon signaling is as follows. TDD-UL-DL-Pattern defines two patterns pattern1 and pattern2, where pattern2 is optional, and the dl-UL-TransmissionPeriodicity field defines a period of up to 10ms. Under the dual-cycle structure, it can be assembled into the frame structure shown in Figure 1. The maximum length of each pattern is 10ms. Figure 1 is a schematic diagram of the dual-cycle frame structure configuration. For the time slot format, the maximum length is 20ms, and the maximum number of slots is 640, corresponding to a 480kHz sub-carrier spacing (SCS). For example, the maxNrofSlots field below defines a maximum of 320 slots within a 10ms period.

[0036] The following is a schematic diagram of the configuration signaling of the symbol number and time slot.

[0037] Table 1 Number of OFDM symbols in each time slot, number of time slots in each radio frame, and number of time slots in each subframe under normal cyclic prefix

[0038] Table 2 Number of OFDM symbols in each time slot, number of time slots in each radio frame, and number of time slots in each subframe under extended frame cyclic prefix

[0039] It can be seen from the above records that for the frame structure configured using the tdd-UL-DL-ConfigurationCommmon signaling, a maximum period of 20ms is supported.

[0040] The semi-static UE-specific frame structure configuration is configured through the tdd-UL-DL-ConfigDedicated signaling. The specific signaling content is shown below, where SlotIndex identifies the time slot in the time slot period configured in the tdd-UL-DL-configurationCommon signaling. It can also be seen that the frame structure range configured by the tdd-UL-DL-ConifgDedicated signaling will not exceed the tdd-UL-DL-configurationCommon period. The tdd-UL-DL-SlotConfig is based on the value of maxNrofSlots, and the maximum value of maxNrofSlots corresponds to 10ms. The UE-specific configuration can only reconfigure the X slot / symbol of the Cell-specific configuration, as shown in Figure 2. Figure 2 is a schematic diagram of the flexible configuration frame structure, where D represents the downlink frame, U represents the uplink frame, and X represents the flexibly configurable frame. In addition, TDD-UL-DL-ConfigDedicated signaling can only modify the frame structure of a maximum of 10ms, because TDD-UL-DL-SlotConfig is based on the value of maxNrofSlots, and maxNrofSlots corresponds to a maximum of 10ms, but cannot be modified for the dual slot pattern mode (20ms period).

[0041] From the above records, it can be seen that for the frame structure configured using tdd-UL-DL-ConfigDedicated signaling, the maximum supported period is 10ms, and there is a mismatch problem with tdd-UL-DL-ConfigurationCommmon signaling, that is, there is no dual period configuration.

[0042] For the dynamic frame structure configured by Group Common signaling, SFI is an optional function. If the UE receives both semi-static and dynamic frame structure configurations, SFI is meaningful only in the "X" slot of the semi-static frame structure configuration. In other words, SFI can only be reconfigured for the X slot, as shown in Figure 2.

[0043] The SlotFormatIndicator information element is used to configure the Group-Common-PDCCH that monitors the SFI.

[0044] The SlotFormatCombinationsPerCellinformation element is used to configure the available slot format combinations (SlotFormatCombinations) of a serving cell.

[0045] Each SlotFormatCombination corresponds to a combination identifier (combination id) and a set of time slot formats (slot format), where SlotFormatCombination can be configured with up to 512 (9 bits) and Slot format can be configured with up to 256, as shown in Figure 3. Figure 3 is the time slot format table under the normal cyclic prefix. It can be seen that a maximum of 256 frame structure configurations are provided.

[0046] An example of the SFI signaling format is shown in FIG4 , which is a schematic diagram of the SFI signaling format. FIG4 shows that DCI format 2-0 signaling includes N SFI indexes, SFI_index0 to SFI_indexN, each of which indicates a set of solt formats. For example, SFI_index0 indicates that the slot format for a combination ID of 3 in cell 1 (Cell1) is 255. The specific format content can be obtained by querying the table shown in FIG3 . SFI_index1 indicates that the slot formats for a combination ID of 0 in cell 2 (Cell2) are 7, 2, and 1. Multiple slot formats can be configured cyclically, and the specific format content can be obtained by querying the table shown in FIG3 .

[0047] In addition, the slot format length configured in the combination must be greater than the SFI monitoring period, so the SFI sent in different periods can indicate the frame structure in different periods. Assuming that AI / ML can predict the frame structure configuration for a longer period of time, the number of blind detections of SFI can be reduced. Based on the standard, the number of slot formats in each combination must be configured very large through Radio Resource Control (RRC) messages. However, the more slot formats in each combination, the more combinations can be combined. The problem with such configured Grpup common signaling is that it may increase signaling overhead or the number of blind detections when configured over a long period.

[0048] FIG5 is a flowchart of an enhanced frame structure configuration method provided in an embodiment of the present application. As shown in FIG5 , the enhanced frame structure configuration method provided in this embodiment includes:

[0049] S510: Configure enhanced frame structure length information in the first signaling, where the enhanced frame structure length information includes information for indicating the time domain length of the radio frame.

[0050] The enhanced frame structure configuration method provided in this embodiment is used to configure an enhanced frame structure length for the UE, wherein the enhanced frame structure length is a more flexible time domain length of the radio frame, which can provide a longer time domain length for the radio frame. With the introduction of AI / ML technology, longer-term service prediction can be achieved based on AI / ML technology. Therefore, configuring a longer time domain length for the radio frame can make service scheduling more flexible. The enhanced frame structure configuration method provided in this embodiment is applied to the base station, and the base station configures the enhanced frame structure length for the UE and sends the enhanced frame structure length information to the UE through signaling.

[0051] First, the base station configures enhanced frame structure length information in the first signaling. The enhanced frame structure length information includes information indicating the time domain length of the radio frame. The first signaling can be any type of control signaling sent by the base station to the UE, or the first signaling can be signaling information carried in data sent by the base station to the UE in other forms. The enhanced frame structure length information can be carried in the first signaling in various forms, such as configuring a new field in the first signaling, configuring a new parameter value in an existing field in the first signaling, or providing an additional dedicated area in the header of the first signaling. The enhanced frame structure length information is used to indicate the time domain length of the radio frame. As described above, the frame structure length of a radio frame can be indicated in various forms, such as a pattern, time domain length, or a time slot format combination. Therefore, in this embodiment, an enhanced frame structure length, i.e., indication of a longer time domain length of the radio frame, can be achieved by extending any of the aforementioned radio frame structure length indication forms. In the following embodiments, various enhanced frame structure length indication methods are described in detail. The enhanced frame structure length information is different from the information used to indicate the frame structure length in the current wireless communication system. The enhanced frame structure length information can indicate a radio frame with a longer time domain length, thereby supporting longer time domain service prediction.

[0052] The configuration of enhanced frame structure length information in the first signaling can be triggered by the base station, that is, to cooperate with the base station's long-period service prediction. AI / ML can also be a UE-side model, that is, the UE side performs service prediction, and the UE may estimate a long-period time slot format, and then the UE will feedback the estimated long-period time slot format to the base station. Then, after receiving the long-period time 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.

[0053] S520: Send a first signaling to the UE.

[0054] After the base station configures the enhanced frame structure length information in the first signaling, it can send the first signaling to the UE. Since the enhanced frame structure length information is configured in the first signaling, the UE that receives the first signaling can determine the time domain length of the wireless frame based on the enhanced frame structure length information. Since the enhanced frame structure length information is more flexible than the traditional wireless frame length indication in the 5G system and supports a longer time domain length, when the communication system uses AI / ML technology to make longer-term business predictions, it can use wireless frames with longer time domain lengths to match longer time domain business prediction results. Therefore, the enhanced frame structure configuration method provided in this embodiment provides support for business applications of mobile communication systems in longer time domains.

[0055] The enhanced frame structure configuration method provided in this embodiment configures enhanced frame structure length information in the first signaling, wherein the enhanced frame structure length information includes information for indicating the time domain length of the wireless frame, and then sends the first signaling to the UE, thereby providing a more flexible wireless frame time domain length configuration strategy, which can support wireless frames with longer time domain lengths and can provide flexible wireless frame time domain length support for services.

[0056] For the above three NR frame structure configurations, the enhanced frame structure configuration method provided in the embodiment of the present application can be implemented by extending the signaling of the three NR frame structure configurations, 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 added to the above signaling, or the field used to indicate the time domain length of the wireless frame in the above signaling is extended to enhanced frame structure length information. Or the first signaling is a new signaling specifically used to indicate the enhanced frame structure length information. The method of extending the signaling used to configure the current NR frame structure can better be compatible with the previous version of NR signaling, while reducing the signaling consumption of additional configuration.

[0057] The enhanced frame structure configuration method provided in the embodiment of the present application is described in detail below for cases where the first signaling is different signaling.

[0058] When the first signaling is general signaling for configuring a semi-static cell-specific frame structure (semi-static cell-specific frame structure), the enhanced frame structure length information includes the number N of patterns in the extended radio frame, where N is greater than 2.

[0059] The general signaling for configuring the dedicated frame structure for semi-static cells may be, for example, the aforementioned tdd-UL-DL-ConfigurationCommmon signaling. In the aforementioned general signaling for configuring the dedicated frame structure for semi-static cells, a configuration of up to 2 radio frame patterns is supported. In an embodiment of the present application, the number of patterns N in the extended radio frame is configured in the general signaling for configuring the dedicated frame structure for semi-static cells, where N is greater than 2, that is, the number of patterns of more than 2 radio frames can be provided, and the frame structure indication under a larger radio frame length is supported, for example, greater than 20ms. It is sufficient to add additional radio frame pattern configurations as needed at the location where the radio frame pattern was originally configured in the general signaling for configuring the dedicated frame structure for semi-static cells. Since the general signaling for configuring the dedicated frame structure for semi-static cells is a configuration for the serving cell, all UEs in the serving cell will receive the signaling and obtain the enhanced frame structure length information.

[0060] 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 following: the number of patterns M in the extended wireless frame, and the time domain length information of the wireless frame, where M is greater than or equal to 2.

[0061] The dedicated signaling used to configure the semi-static UE-specific frame structure may be, for example, the aforementioned tdd-UL-DL-ConfigDedicated signaling. In the dedicated signaling used to configure the semi-static UE-specific frame structure, the enhanced frame structure length information may also be indicated by 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. Alternatively, the time domain length information of the radio frame may be extended in the dedicated signaling used to configure the semi-static UE-specific frame structure. Specifically, the number of radio frames may be configured. For example, if the time occupied by a radio frame in the time domain is 10 ms, the number of radio frames P may be configured. For example, when P = 4, reconfiguration of X time slots on a continuous 40 ms frame structure is allowed, as shown in FIG6 , which is a schematic diagram of the extended frame structure configuration provided in an embodiment of the present application, where D represents a downlink frame, U represents an uplink frame, and X represents a flexibly configurable frame. Alternatively, in the dedicated signaling used to configure 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 configured simultaneously.

[0062] The number of patterns in the extended radio frame is configured in a dedicated configuration or in a serving cell configuration, that is, the number of patterns in the extended radio frame can be configured in a dedicated configuration for the UE, and is configured only for a specific UE; or the number of patterns in the extended radio frame can also be configured in the serving cell configuration, and is configured for all UEs in the serving cell.

[0063] The following takes tdd-UL-DL-ConfigDedicated signaling as an example to schematically illustrate the specific enhanced frame structure length information.

[0064] First, the 10ms radio frame boundary restriction can be removed by configuring TDD-UL-DL-SlotIndex and introducing a configurable P value, TDD-UL-DL-SlotIndex::=INTEGER(0..P*maxNrofSlots-1).

[0065] Alternatively, a pattern can be added to the TDD-UL-DL-ConfigDedicated signaling, and the number of patterns is configurable. This signaling is dedicated to the UE, as shown below:

[0066] Alternatively, you can add a pattern in ServingCellConfig, and the number of patterns is configurable. This signaling is for the serving cell, as shown below.

[0067] Since the dedicated signaling for configuring the semi-static UE-specific frame structure is configured for the UE, the enhanced frame structure can be configured separately for different UEs, and different UEs can perform the required services according to the time domain length of the radio frame indicated by the dedicated signaling configured for them.

[0068] When the first signaling is a general signaling for configuring a dynamic dedicated frame structure (Group common frame structure), the enhanced frame structure length information includes the period or duration of the extended radio frame.

[0069] The general signaling used to configure the dynamic dedicated frame structure can be, for example, the aforementioned DCI format 2_0, i.e., SFI. In the general signaling used to configure the dynamic dedicated frame structure, new indication information is added to indicate the periodicity or duration of the radio frame. This indication information indicates the period of a radio frame or the duration of a radio frame. The extended radio frame period or duration is located in a dedicated area of ​​the first signaling header. That is, a header area is added to the original signaling to carry the extended radio frame period or duration. Other common information may also be notified in the newly added header area. The extended radio frame period or duration in the dedicated area of ​​the first signaling header is used to indicate the period or duration of the time slot format combination of one or more consecutive radio frames, that is, the extended radio frame period or duration carried in the dedicated area of ​​the first signaling header can be used to indicate the period or duration of the time slot format combination of one radio frame, or the extended radio frame period or duration carried in the dedicated area of ​​the first signaling header can be used to indicate the period or duration of the time slot format combination of multiple consecutive radio frames. As shown in Figure 3, the time slot format combination of a radio frame is determined according to its format number. After adding the extended radio frame period or duration, the time slot format combination of multiple consecutive radio frames can be indicated, that is, the time slot format numbers of multiple consecutive radio frames can be indicated. As shown in Figure 7, Figure 7 is a schematic diagram of the format of different DCI format2_0 signaling. As can be seen from the figure, the original DCI format2_0 signaling includes N SFI indexes, and each SFI index from SFI_index0 to SFI_indexN is used to indicate a group of solt formats, as shown in Figure 4. The extended DCI format2_0 signaling can add a dedicated header area (Head) before N consecutive SFI indexes to indicate the period or duration of the radio frame indicated by the following N consecutive SFI indexes. Or the extended DCI format2_0 signaling can add a dedicated header area (Head) before each SFI index of the N SFI indexes to indicate the period or duration of the radio frame indicated by the following 1 SFI index. Or the period or duration of the extended radio frame can be carried in the first signaling. For example, by modifying the RRC configuration, a field is added to the current SFI information to indicate the time slot format combination of multiple radio frames, as shown below:

[0070] In addition, the period or duration of the extended radio frame can be UE-specific configuration information or cell-specific configuration information. That is, when configuring the period or duration of the extended radio frame, it can be configured for a specific UE or for a serving cell. For example, it can be added to SlotFormatCombinationPerCell and this unified period can be used for all slotFormatCombinations, as shown below:

[0071] For the case where the first signaling is a general 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 will break the restriction that the lengths of multiple time slot formats in the time slot combination must be greater than the SFI blind detection period, that is, a smaller time slot format length can be configured to achieve a longer SFI indication. Specifically, the blind detection period of the first signaling is the 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, the blind detection monitoring on the corresponding SFI monitoring period (Monitor occasion, MO) within the period or duration can be ignored. When the first SFI blind detection period after the configured period or duration arrives, a new SFI is triggered. At this time, the actual SFI blind detection period is the larger value of the preset SFI blind detection 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 smaller value of the extended wireless frame period or duration and the preset SFI blind detection period can be used as the new blind detection period of SFI for SFI detection.

[0072] FIG8 is a flowchart of another enhanced frame structure configuration method provided in an embodiment of the present application. As shown in FIG8 , the enhanced frame structure configuration method provided in this embodiment includes:

[0073] S810: Detect first signaling sent by a base station, where enhanced frame structure length information is configured in the first signaling, and the enhanced frame structure length information includes information for indicating a time domain length of a radio frame.

[0074] The enhanced frame structure configuration method provided in this embodiment is used for the UE to transmit data according to the enhanced frame structure length configured by the base station, wherein the enhanced frame structure length is a more flexible time domain length of the wireless frame, which can provide a longer time domain length for the wireless frame. With the introduction of AI / ML technology, longer-term service prediction can be achieved based on AI / ML technology. Therefore, configuring a longer time domain length for the wireless frame can make the scheduling of services more flexible. The enhanced frame structure configuration method provided in this embodiment is applied to the UE, and the UE obtains the signaling sent by the base station to obtain the enhanced frame structure length configured by the base station for the UE, and then receives or sends data according to the enhanced frame structure length information.

[0075] First, the UE detects first signaling sent by a base station. The first signaling is configured with enhanced frame structure length information, which includes information indicating the time domain length of a radio frame. The enhanced frame structure length information is configured by the base station. The first signaling can be any type of control signaling sent by the base station to the UE, or the first signaling can be signaling information carried in other forms within data sent by the base station to the UE. The enhanced frame structure length information can be carried in the first signaling in various forms, such as configuring a new field in the first signaling, configuring a new parameter value within an existing field in the first signaling, or providing an additional dedicated area in the header of the first signaling. The enhanced frame structure length information is used to indicate the time domain length of the radio frame. As described above, the frame structure length of a radio frame can be indicated in various forms, such as a pattern, time domain length, or a combination of time slot formats. Therefore, in this embodiment, an enhanced frame structure length, i.e., an indication of a longer time domain length of a radio frame, can be achieved by extending any of the aforementioned radio frame structure length indication forms. In the aforementioned 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 to indicate the frame structure length in the current wireless communication system. The enhanced frame structure length information can indicate a radio frame with a longer time domain length, thereby supporting longer time domain service prediction.

[0076] The configuration of enhanced frame structure length information in the first signaling may be triggered by the base station, that is, to cooperate with the long-period service prediction of the base station. AI / ML may also be a UE-side model, that is, the UE side performs service prediction, and the UE may estimate a long-period time slot format, and then the UE will feedback the estimated long-period time slot format to the base station. Then, after receiving the long-period time slot format prediction information sent by the UE, the base station configures the enhanced frame structure length information in the first signaling based on the information fed back by each UE. Therefore, before S810, it may also include the following: predicting the long-period time slot format; sending the long-period time slot format prediction information to the base station.

[0077] S820: Receive or send data according to the enhanced frame structure length information.

[0078] After the base station configures the enhanced frame structure length information in the first signaling, it can send the first signaling to the UE. Since the enhanced frame structure length information is configured in the first signaling, the UE that receives the first signaling can determine the time domain length of the wireless frame according to the enhanced frame structure length information, and receive or send data according to the enhanced frame structure length information. Since the enhanced frame structure length information is more flexible than the traditional wireless frame length indication in the 5G system and supports a longer time domain length, when the communication system uses AI / ML technology to make longer-term business predictions, it can use wireless frames with longer time domain lengths to match longer time domain business prediction results. Therefore, the enhanced frame structure configuration method provided in this embodiment provides support for business applications of mobile communication systems in longer time domains.

[0079] The enhanced frame structure configuration method provided in this embodiment detects the first signaling sent by the base station, wherein the first signaling is configured with enhanced frame structure length information, and the enhanced frame structure length information includes information for indicating the time domain length of the wireless frame. Then, data is received or sent according to the enhanced frame structure length information, providing a more flexible wireless frame time domain length configuration strategy, which can support wireless frames with longer time domain lengths and can provide flexible wireless frame time domain length support for services.

[0080] Similar to the embodiment shown in FIG5 , when the first signaling is different signaling, the specific configuration method of the first signaling has been described in detail in the aforementioned embodiment and will not be repeated here.

[0081] When the first signaling is a general signaling for configuring a dynamic dedicated frame structure, after detecting the first signaling sent by the base station, it also includes: taking the larger value of the period or duration of the extended wireless frame and the blind detection period of the preset first signaling as the blind detection period of the first signaling. After taking the larger value of the period or duration of the extended wireless frame and the blind detection period of the preset first signaling as the blind detection period of the first signaling, it also includes: if the period or duration of the extended wireless frame is used as the blind detection period of the first signaling, no new first signaling is detected in the first blind detection period, then taking the smaller value of the period or duration of the extended wireless frame and the blind detection period of the preset first signaling as the new blind detection period of the first signaling. Figure 9 is a schematic diagram of the blind detection period of the first signaling. As shown in Figure 9, taking the duration of the extended wireless frame as an example, after the extended duration is carried in the first signaling, within the extended duration, if the original SFI blind detection period ends and is still within the extended duration, the blind detection of SFI is stopped until the first SFI blind detection period within the next extended duration is reached and the blind detection of SFI is performed again.
