Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of communications, and in particular, to an adaptive gain control method and device, a storage medium, and an electronic device. Background Art

[0002] In the Long Term Evolution (LTE) system, also known as the 4G system, only a 15kHz subcarrier spacing (SCS) is supported, corresponding to a 1ms time length of an LTE subframe (SF), of which 1ms includes 14 LTE orthogonal frequency division multiplexing (OFDM) symbols. In the New Radio (NR) system, also known as the 5G system, in order to overcome the Doppler shift effect caused by higher mobile speeds, a larger SCS, such as 30kHz, is supported. Since the SCS and the time length of an OFDM are reciprocal to each other, this means that when the SCS is 30kHz, the time length of an NR OFDM is reduced to 1 / 2 of that of LTE OFDM, and the time length of an NR SF is changed to 0.5ms, of which 0.5ms includes 14 NR OFDM symbols. One SF can be regarded as a service scheduling unit.

[0003] In the current system, the demand for direct communication between user equipment (UE) is becoming stronger and stronger, such as in games, fleets, groups and other scenarios. When the UE receives, it is often necessary to perform an automatic gain control (AGC) operation, that is, the received signal power must first be adjusted to a reasonable range to avoid saturation of the analog-to-digital converter (ADC) and the introduction of quantization errors. The adjusted receiving gain remains unchanged throughout the SF time range. When the UE communicates with UEs of different systems, due to different subcarrier spacings and different time lengths of service scheduling units of different systems, it is impossible to ensure that the receiving gain adjusted in the front section is suitable for the LTE SF back section data. This is called AGC mismatch, that is, there is a quantization error in the LTE SF back section data. Summary of the invention

[0022] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] When UE1 communicates only with UE2, or UE1 communicates with LTE UE3 and LTE UE4 at the same time, and UE3 and UE4 are both LTE UEs, their subcarrier spacing is the same, so the service scheduling unit is of equal length, that is, the receiving power within the time range of the service scheduling unit is unchanged, that is, AGC is not required within the time range of the service scheduling unit. However, when UE1 communicates with LTE UE3 and NR UE4 at the same time, the subcarrier spacing used by LTE and NR is different, so the time length of the LTE service scheduling unit and the NR service scheduling unit is different, and it is impossible to ensure that the receiving gain adjusted in the front section is suitable for the LTE SF back section data. This is called AGC mismatch. Figure 1 This is a schematic diagram of AGC adaptation in related technology, such as Figure 1 As shown in FIG. 1 , the received power of the LTE SF back-end data is too low, which introduces quantization errors. Figure 2 This is a schematic diagram of AGC adaptation in related technology, such as Figure 2 As shown, the LTESF back-end data receiving power is too high, which introduces quantization errors.

[0025] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a computer terminal as an example, Figure 3 is a hardware structure block diagram of a computer terminal of an adaptive gain control method according to an embodiment of the present disclosure, such as Figure 3 As shown, the computer terminal may include one or more ( Figure 3 Only one is shown in the figure) a processor 302 (the processor 302 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 304 for storing data, wherein the above-mentioned computer terminal may also include a transmission device 306 and an input and output device 308 for communication functions. It can be understood by those skilled in the art that Figure 3 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer terminal. Figure 3 More or fewer components as shown, or with Figure 3 Different configurations shown.

[0026] The memory 304 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the adaptive gain control method in the embodiment of the present disclosure. The processor 302 executes various functional applications and data processing by running the computer program stored in the memory 304, that is, the above method is implemented. The memory 304 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 304 may further include a memory remotely arranged relative to the processor 302, and these remote memories can be connected to the computer terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0027] The transmission device 306 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of a computer terminal. In one example, the transmission device 306 includes a network adapter (Network Interface Controller, NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 306 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0028] In this embodiment, an adaptive gain control method running on the above-mentioned computer terminal is provided. Figure 4 is a flow chart of an adaptive gain control method according to an embodiment of the present disclosure. Figure 4 As shown, the process includes the following steps:

[0029] Step S402, the first user equipment receives signals from the second user equipment and the third user equipment, wherein the first user equipment communicates with the second user equipment using the first subcarrier spacing and the first type of service scheduling unit, the first user equipment communicates with the third user equipment using the second subcarrier spacing and the second type of service scheduling unit, and the signals include the first type of service scheduling unit and the second type of service scheduling unit;

[0030] In an exemplary embodiment, the second subcarrier spacing is N times the first subcarrier spacing, and the time length of the first type of service scheduling unit is N times the time length of the second type of service scheduling unit, where N is a positive integer.

[0031] In the actual implementation process, when the first user equipment communicates with different user equipment, namely the second user equipment and the third user equipment, since the second user equipment and the third user equipment belong to different communication systems, for example, the second user equipment belongs to the 4G system and the third user equipment belongs to the 5G system, the first user equipment will select different types of subcarrier spacing and service scheduling units when communicating with them. In the above communication process, the first user equipment serves as the receiving end, and the second user equipment and the third user equipment serve as the transmitting end. Specifically, for example, the first type of service scheduling unit may be an LTE service scheduling unit, and the second type of service scheduling unit may be an NR service scheduling unit, wherein the first subcarrier spacing of the LTE service scheduling unit is 15kHz, and the second subcarrier spacing of the NR service scheduling unit is 30kHz. In view of the reciprocal relationship between the subcarrier spacing SCS and the time length of the OFDM symbol, the time length of the LTE service scheduling unit is twice that of the NR service scheduling unit, that is, the time length of the first type of service scheduling unit is twice the time length of the second type of service scheduling unit, and N is equal to 2 at this time. During the specific implementation process, if a larger SCS is needed to overcome related influences such as Doppler frequency shift, the frequency value of the second subcarrier interval can continue to increase, and the corresponding first-category service scheduling unit time length is a multiple of the second-category service scheduling unit time length N, which also increases. This is only an example and is not specifically limited.

[0032] Step S404: The first user equipment performs one or more adaptive gain controls on the signal.

[0033] During the specific implementation process, the first user equipment may perform one or more adaptive gain controls on the received signal according to actual conditions.

[0034] In an exemplary embodiment, before the first user device receives signals from the second user device and the third user device, it also includes: the first user device receives a first notification message from the third user device, wherein the first notification message indicates whether the signal contains a long-format second-class service scheduling unit, wherein the long-format second-class service scheduling unit is formed by merging N second-class service scheduling units and has the same time length as a first-class service scheduling unit.

[0035] In the actual implementation process, if the second user equipment belongs to the 4G system and the third user equipment belongs to the 5G system, the time length of the LTE service scheduling unit is twice that of the NR service scheduling unit, that is, the time length of the first type of service scheduling unit is twice that of the second type of service scheduling unit, and N is equal to 2 at this time. That is, the long-format second-type service scheduling unit is formed by merging two second-type service scheduling units. Specifically, the long-format second-type service scheduling unit is obtained by merging two second-type service scheduling units, and the signal of the third user equipment received by the first user equipment, that is, the NR service scheduling unit, has the same receiving power. Therefore, it is only necessary to perform adaptive gain control once at the front end position of the signal, and correspondingly, the signal from the second user equipment, that is, the front end position of the LTE service scheduling unit, is also adaptively controlled once, that is, when the signal includes a long-format second-type service scheduling unit, the first user equipment performs adaptive gain control once at the front end position of the signal. This ensures that the total received power of the signal is within the quantization range of the ADC, wherein the quantization range of the ADC is determined based on the AGC adjustment. When receiving a signal, the first user device at the receiving end will first perform AGC control to ensure that the power of the received signal is within a reasonable range, that is, within the quantization range of the ADC. In this way, for the first user device, it can be ensured that the signal received by the first user device is within the quantization range that is expected in advance and obtained through the AGC adjustment, thereby minimizing or avoiding the quantization error in the subsequent ADC step.

[0036] For the embodiments of the present disclosure, when the signal includes a long-format second-category service scheduling unit, the first user device performs an adaptive gain control at the front end of the signal, and the second-category service scheduling unit from the third user device is merged into a long-format second-category service scheduling unit, so that the time length of the second-category service scheduling unit is aligned with that of the first-category service scheduling unit, and the receiving power of the second-category service scheduling unit itself does not change. Therefore, by performing an adaptive gain control at the front end of the signal, the quantization range of the receiving power of the signal, i.e., the receiving power of the first-category service scheduling unit and the receiving power of the second-category service scheduling unit, can be obtained. In the subsequent signal reception process, because the receiving power of the first-category service scheduling unit and the receiving power of the second-category service scheduling unit do not continue to change, there is no need to continue to perform AGC adjustment, and the total receiving power can be ensured to be within the ADC quantization range, i.e., the receiving power of the first-category service scheduling unit and the receiving power of the second-category service scheduling unit are always within the ADC quantization range.

[0037] In an exemplary embodiment, when the signal does not include a long-format second-category service scheduling unit, the first user device performs adaptive gain control at the starting position of the first part and the starting position of the second part of the first-category service scheduling unit of the signal, respectively, wherein the first-category service scheduling unit includes a first part and a second part, and the first part or the second part is of the same length as the second-category service scheduling unit.

[0038] In the actual implementation process, the second-class service scheduling units are not merged to obtain the second-class service scheduling units in a long format. After the front-end position of the first-class service scheduling unit is adjusted by AGC, since the receiving power of the second-class service scheduling unit for communication reception by the third user equipment is different from the receiving power of the first-class service scheduling unit, it is necessary to perform AGC adjustments at the front-end position of the second-class service scheduling unit and the corresponding position of the first-class service scheduling unit aligned with the front-end position of the second-class service scheduling unit, respectively, so that the total receiving power of the second-class service scheduling unit and the first-class service scheduling unit is within the quantization range of the ADC, wherein the explanation of the quantization range of the ADC has been described in the aforementioned embodiment and will not be repeated here. Specifically, since the receiving time of the second-class service scheduling unit is uncertain, the alignment position of the second-class service scheduling unit with the first-class service scheduling unit is uncertain, and therefore the first part or the second part of the above-mentioned first-class service scheduling unit is the same length as the second-class service scheduling unit (aligned).

[0039] In an exemplary embodiment, the first notification message also includes an indication of whether the powers of the plurality of second-category service scheduling units constituting the long format are the same.

[0040] According to the indication that the power of multiple second-category service scheduling units constituting the long format is the same as that included in the above-mentioned first notification message, in an exemplary embodiment, when the signal includes a second-category service scheduling unit in a long format and the power of the multiple second-category service scheduling units constituting the long format is different, the first user equipment performs an adaptive gain control at the front end position of the signal, and performs adaptive gain control at the position where the first-category service scheduling unit is aligned with the second-category service scheduling units of different power. In an exemplary embodiment, when the signal includes a second-category service scheduling unit in a long format and the power of multiple second-category service scheduling units constituting the long format is the same, the first user equipment performs an adaptive gain control at the front end position of the signal. In the specific implementation process, when the signal includes a second-category service scheduling unit in a long format and the power of multiple second-category service scheduling units constituting the long format is the same, the second-category service scheduling unit in the long format may be merged or may be possessed by the signal itself.

[0041] In an exemplary embodiment, the first notification message further indicates whether the long format second type service scheduling unit is filled with dummy data, as well as the location of the dummy data and the size of the dummy data.

[0042] In the actual implementation process, the number of second-category service scheduling units from the third user device is insufficient to support the merging to obtain the long-format second-category service scheduling unit, that is, the number of transmission data from the third user device is insufficient to be used to merge to obtain the long-format second-category service scheduling unit. In order to obtain the long-format second-category service scheduling unit, it is necessary to fill the long-format second-category service scheduling unit with virtual data. Therefore, the first notification message also indicates whether the long-format second-category service scheduling unit is filled with virtual data; in the case where the long-format second-category service scheduling unit is filled with virtual data, the first notification message also indicates the position of the virtual data and the size of the virtual data, and the first user device performs an adaptive gain control at the front end of the signal.

[0043] During the specific implementation process, the purpose of the first notification message also indicating the position and size of the virtual data is that after the first user device completes receiving the signal, it is necessary to identify and extract the signal. Only when the first user device receives the first notification message from the third user device and the first notification message also indicates the position and size of the virtual data, can the first user device extract the virtual data of the corresponding size from the corresponding position of the long-format second-class service scheduling unit and obtain the original second-class service scheduling unit that needs to be transmitted and acquired.

[0044] Through the above steps, the first user equipment receives signals from the second user equipment and the third user equipment, wherein the first user equipment communicates with the second user equipment using the first subcarrier spacing and the first type of service scheduling unit, and the first user equipment communicates with the third user equipment using the second subcarrier spacing and the second type of service scheduling unit, and the signal includes the first type of service scheduling unit and the second type of service scheduling unit; the first user equipment performs one or more adaptive gain controls on the signal. The problem of quantization error in automatic gain control of received signals in the related art is solved, and the effect of reducing the quantization error when the user equipment performs automatic gain control on the received signal is achieved.

[0045] The execution subject of the above steps may be a base station, a terminal, etc., but is not limited thereto.

[0046] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present disclosure, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a disk, or an optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present disclosure.

Thus, the present disclosure is not limited to any specific combination of hardware and software.

[0064] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, it is described below in conjunction with specific scenario embodiments.

[0065] Scenario Example 1

[0066] Figure 7 is a flow chart of an adaptive gain control method according to an embodiment of the present disclosure, such as Figure 7 As shown, first, determine whether the long-format service scheduling unit is included. If not, it cannot be merged into a long-format second-category service scheduling unit, and you need to set multiple AGCs to receive data after AGC adjustment. If the long-format service scheduling unit is included, it means that the long-format second-category service scheduling unit can be merged. At this time, you need to determine whether virtual data is included. If virtual data is included, and virtual data is used when merging the long-format second-category service scheduling unit, you need to discard the virtual data after receiving the data.

[0067] Specifically, when virtual data is included and virtual data is used when merging the grown format second type business scheduling units, it means that the data to be transmitted does not contain data for merging the grown format second type business scheduling units, that is, the original data to be transmitted only supports the merging of the grown format second type business scheduling units, but there is no data for merging, so it is necessary to fill in virtual data for merging.

[0068] Specifically, when the long-format service scheduling unit is not included, multiple AGCs need to be set. Depending on the power of the second-category service scheduling unit, the situations for setting the AGCs are also different. The specific situation classification will be further described in the subsequent embodiments.

[0069] Figure 8 is a schematic diagram of AGC adjustment according to an embodiment of the present disclosure, such as Figure 8 As shown, the first user equipment performs AGC adjustment at the first OFDM symbol position of the subframe, and ensures that the total receiving power from the first OFDM symbol to the seventh OFDM symbol of the LTE subframe and the first OFDM symbol to the fourteenth OFDM symbol of the NR subframe is within the quantization range of the ADC through the receiving gain X1; the first user equipment performs AGC adjustment at the eighth OFDM symbol position of the subframe, and ensures that the total receiving power from the eighth OFDM symbol to the fourteenth OFDM symbol of the LTE subframe is within the quantization range of the ADC through the receiving gain Y1, and thus the total receiving power of the signals from the two transmitting ends, namely, the LTE service scheduling unit and the NR service scheduling unit, is within the quantization range of the ADC.

[0070] like Figure 8 As shown, in this scenario embodiment, the LTE subframe includes multiple LTE service scheduling units, wherein the LTE service scheduling unit is the first type of service scheduling unit in the above embodiment, and the NR subframe includes multiple NR service scheduling units, wherein the NR service scheduling unit is the second type of service scheduling unit in the above embodiment.

[0071] like Figure 8As shown, the second type of service scheduling unit, i.e., the NR service scheduling unit, is not merged, and virtual data is not filled to obtain the long format NR service scheduling unit, so multiple AGC adjustments are required, specifically, as Figure 8 As shown, an AGC adjustment is performed at the front end position of the LTE service scheduling unit, i.e., the first OFDM symbol, and an AGC adjustment is performed at the front end position of the NR service scheduling unit. At the same time, an AGC adjustment is also required at the 8th OFDM symbol position, i.e., the middle position where the LTE service scheduling unit and the NR service scheduling unit are aligned.

[0072] In this embodiment, by setting a plurality of AGC symbols and maintaining the service scheduling unit format in the existing system, the receiving end can accurately perform AGC adjustment at the position where the power changes.

[0073] Scenario Example 2

[0074] In this scenario embodiment, the LTE subframe includes multiple LTE service scheduling units, wherein the LTE service scheduling unit is the first type of service scheduling unit in the above embodiment, and the NR subframe includes multiple NR service scheduling units, wherein the NR service scheduling unit is the second type of service scheduling unit in the above embodiment.

[0075] The similarities between this scenario embodiment and scenario embodiment 1 are that the second type of service scheduling unit, i.e., the NR service scheduling unit, is not merged, and virtual data is not filled to obtain a long-format NR service scheduling unit. The difference between this scenario embodiment and scenario embodiment 1 is that the alignment position of the LTE service scheduling unit and the NR service scheduling unit is different, that is, the LTE service scheduling unit in the above embodiment can be divided into a first part and a second part, wherein the first part or the second part is equal to the time length of the NR service scheduling unit.

[0076] Fig. 9 is a schematic diagram of AGC adjustment according to an embodiment of the present disclosure, such as Fig. 9 As shown, the first user equipment performs AGC adjustment at the first OFDM symbol position of the subframe, and ensures that the received power from the first OFDM symbol to the seventh OFDM symbol of the LTE subframe is within the quantization range of the ADC through the receiving gain X2; the first user equipment performs AGC adjustment at the eighth OFDM symbol position of the subframe, and ensures that the total received power from the eighth OFDM symbol to the fourteenth OFDM symbol of the LTE subframe and the first OFDM symbol to the fourteenth OFDM symbol of the NR subframe is within the quantization range of the ADC through the receiving gain Y2.

[0077] In this embodiment, by setting a plurality of AGC symbols and maintaining the service scheduling unit format in the existing system, the receiving end can accurately perform AGC adjustment at the position where the power changes.

[0078] Scenario Example 3

[0079] In this scenario embodiment, the LTE subframe includes multiple LTE service scheduling units, wherein the LTE service scheduling unit is the first type of service scheduling unit in the above embodiment, and the NR subframe includes multiple NR service scheduling units, wherein the NR service scheduling unit is the second type of service scheduling unit in the above embodiment.

[0080] Fig.10 is a schematic diagram of AGC adjustment according to an embodiment of the present disclosure, such as Fig.10 As shown, the first user equipment performs AGC adjustment at the first OFDM symbol position of the subframe, and ensures that the total received power from the first OFDM symbol to the seventh OFDM symbol of the LTE subframe and from the first OFDM symbol to the fourteenth OFDM symbol of the first NR subframe is within the quantization range of the ADC through the receiving gain X3; the first user equipment performs AGC adjustment at the eighth OFDM symbol position of the subframe, and ensures that the total received power from the eighth OFDM symbol to the fourteenth OFDM symbol of the LTE subframe and from the first OFDM symbol to the fourteenth OFDM symbol of the second NR subframe is within the quantization range of the ADC through the receiving gain Y3.

[0081] like Fig.10 As shown, the receiving powers of multiple NR service scheduling units are different, so it is necessary to perform AGC adjustment at the alignment positions of NR service scheduling units with different receiving powers and LTE service scheduling units. That is, AGC adjustment is performed at the position where the power changes.

[0082] In this embodiment, by setting a plurality of AGC symbols and maintaining the service scheduling unit format in the existing system, the receiving end can accurately perform AGC adjustment at the position where the power changes.

[0083] Scenario Example 4

[0084] In this scenario embodiment, the LTE subframe includes multiple LTE service scheduling units, wherein the LTE service scheduling unit is the first type of service scheduling unit in the above embodiment, and the NR subframe includes multiple NR service scheduling units, wherein the NR service scheduling unit is the second type of service scheduling unit in the above embodiment.

[0085] In this scenario embodiment, multiple NR service scheduling units are merged to obtain a long-format NR service scheduling unit.

[0086] Fig.11is a schematic diagram of AGC adjustment according to an embodiment of the present disclosure, such as Fig.11 As shown, the first user equipment performs AGC adjustment at the first OFDM symbol position of the subframe, and ensures the total receiving power of the first OFDM symbol to the 14th OFDM symbol of the LTE subframe and the first OFDM symbol to the 28th OFDM symbol of the long subframe by combining two NR subframes through the receiving gain X4, and is within the quantization range of the ADC.

[0087] In this embodiment, by merging the service scheduling units into long-format service scheduling units, excessive power changes are avoided, thereby reducing the number of AGC adjustments performed by the receiving end and reducing the number of AGC symbols.

[0088] Scenario Example 5

[0089] In this scenario embodiment, the LTE subframe includes multiple LTE service scheduling units, wherein the LTE service scheduling unit is the first type of service scheduling unit in the above embodiment, and the NR subframe includes multiple NR service scheduling units, wherein the NR service scheduling unit is the second type of service scheduling unit in the above embodiment.

[0090] In this scenario embodiment, a long-format NR service scheduling unit is also obtained, but unlike scenario embodiment four, the number of NR service scheduling units from the third user equipment is insufficient to support merging to obtain a long-format NR service scheduling unit. Therefore, in this scenario embodiment, virtual data padding is used to obtain a long-format NR service scheduling unit.

[0091] Fig.12 is a schematic diagram of AGC adjustment according to an embodiment of the present disclosure, such as Fig.12 As shown, the first user equipment performs AGC adjustment at the first OFDM symbol position of the subframe, and ensures the first OFDM symbol to the 14th OFDM symbol of the LTE subframe and the first OFDM symbol to the 28th OFDM symbol of the long subframe by receiving gain X5, wherein the 15th OFDM symbol to the 28th OFDM symbol are filled with virtual data, and the total received power is within the quantization range of the ADC.

[0092] In this embodiment, by merging the service scheduling unit and filling the dummy data into a long-format service scheduling unit, excessive power changes are avoided, thereby reducing the number of AGC adjustments performed by the receiving end and reducing the number of AGC symbols.

[0093] In implementations one to three of the above scenarios, AGC is set within the service scheduling unit time range. The first user equipment adopts one or more adaptive gain control within the service scheduling unit time to meet the location where the power changes. The receiving end can accurately adjust the AGC to ensure signal quality, thereby further ensuring communication quality.

[0094] In scenario implementation example four, N second service scheduling units are merged into a long format and are equal in length to one first-class service scheduling unit; by merging the service scheduling units into long-format service scheduling units, excessive power changes are avoided, thereby reducing the number of AGC adjustments performed by the receiving end and reducing the number of AGC symbols.

[0095] In the fifth scenario embodiment, the dummy data is filled to form a long-format second-type service scheduling unit, which is equal to one first-type service scheduling unit; by merging the service scheduling unit and the dummy data filled to form a long-format service scheduling unit, excessive power changes are avoided, thereby reducing the number of AGC adjustments performed by the receiving end and reducing the number of AGC symbols. The content of the dummy data here is not important and can be any number.

[0096] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
