The network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a WiFi system, but is not limited thereto.

[0100] In some embodiments, the terminal 102 is, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication capabilities, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0103] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0104] Step 2101: The network device 101 sends second information to the terminal 102.

[0105] In some embodiments, the network device 101 sends second information to the terminal 102 to instruct the terminal to determine whether to send one or more first information.

[0106] In an optional embodiment, the beam squint degree of the first beam sent by the network device 101 to the terminal 102 is relatively light, and the network device 101 may send second information to the terminal 102 to instruct the terminal 102 not to send one or more first information.

[0107] In an optional embodiment, the beam squint degree of the first beam sent by the network device 101 to the terminal 102 is relatively large. The network device 101 can send a second message to the terminal 102 to instruct the terminal 102 to send one or more first messages, thereby assisting the network device 101 to adjust the direction of the first beam and reduce the array gain loss of the first beam.

[0108] In some embodiments, the second information is used to indicate whether the terminal sends one or more first information.

[0109] In some embodiments, the name of the second information is not limited, and may be, for example: "send instruction information", "send execution information", etc.

[0110] In some embodiments, step 2101 is optional, and the terminal 102 may obtain the second information through other devices, or the terminal 102 may determine whether to send one or more first information to the network device 101 based on a protocol agreement.

[0111] For example, if the direction of the first beam sent by the network device 101 is the same as the direction of the actual position of the terminal 102, then the array loss of the first beam sent by the network device 101 to the terminal 102 is small. The network device 101 can send a second message to the terminal 102 to instruct the terminal 102 not to send one or more first messages, thereby avoiding waste of communication resources.

[0112] For example, the network device 101 can send the second information by sending a channel state information reporting configuration (CSI reporting configuration) to the terminal 102, for example, adding a 1-bit information field in the CSI reporting configuration to represent the second information. When the information field is 1, the terminal 102 does not send one or more first information; when the information field is 0, the terminal 102 sends one or more first information.

[0113] Step 2102: The terminal 102 determines whether to send one or more first information to the network device 101 based on the protocol agreement or the second information.

[0114] In some embodiments, the terminal 102 determines to send one or more first information to the network device 101 based on the protocol agreement or the second information to assist the network device 101 in adjusting the direction of the first beam and reducing the array gain loss of the first beam.

[0115] In some embodiments, the terminal 102 determines not to send one or more first information to the network device 101 based on the protocol agreement or the second information to avoid wasting communication resources.

[0116] In some embodiments, the first information is used to indicate the array gain loss of the first beam sent by the network device 101 to the terminal 102 .

[0117] In some embodiments, a first information may be a value of a beam squint level (BSL), wherein the value of the BSL in the interval [0, 1] may be normalized and determined as the first information. When the BSL value is smaller, the array gain loss of the first beam is greater; when the BSL value is larger, the array gain loss of the first beam is smaller.

[0118] In some embodiments, the network device can determine the degree of beam squint of the first beam sent to the terminal, that is, the network device can know the degree of deflection of the subcarriers in the first beam, but since the terminal receiving the first beam may be located in different positions and directions, the array gain loss generated by the terminals in different positions and directions when receiving the first beam may be different, and the network device cannot determine the position direction of each terminal. Therefore, when the network device needs to compensate for the array gain loss of the terminal and adjust the direction of the first beam, the network device can instruct the terminal to send one or more first information by sending the second information, or the terminal can send one or more first information to the network device based on the protocol agreement, so that the network device can determine the position direction of the terminal through the first information, and then compensate for the array gain loss of the terminal according to the position direction of the terminal, and adjust the transmission direction of the first beam.

[0119] In some embodiments, the name of the first information is not limited, and may be, for example, “array gain loss information”, “beam squint information”, etc.

[0120] In some embodiments, step 2102 is optional and may be omitted, and the terminal 102 sends one or more first information to the network device 101 by default.

[0121] Step 2103 : The network device 102 sends third information to the terminal 101 .

[0122] In some embodiments, the network device 102 sends the third information to the terminal 101 so that the terminal 101 can determine whether to compensate for the array gain loss, thereby avoiding waste of communication resources.

[0123] In some embodiments, the third information indicates a first threshold, which may be a preset threshold for the first information. For example, if the first information is a BSL value, the first threshold may be a preset BSL value. When the BSL value in the first information is less than the preset BSL value in the first threshold, it indicates that the row array gain loss of the first beam is significant. In this case, terminal 102 may send instruction information to network device 101 to instruct network device 101 to compensate for the array gain loss.

[0124] In other words, the third information is used to indicate the first threshold, and the first threshold is used to assist the terminal in sending indication information to the network device, where the indication information is used to instruct the network device whether to compensate for array gain loss.

[0125] In some embodiments, the name of the third information is not limited, and it can be, for example, "threshold indication information", "compensation determination information", etc.

[0126] In some embodiments, step 2103 is optional, and the terminal 102 may obtain the third information through other devices, or determine the first threshold indicated in the third information through a protocol agreement.

[0127] Step 2104 : The network device 101 sends a first reference signal to the terminal 102 .

[0128] In some embodiments, the network device 101 sends a first reference signal to the terminal 102, so that the terminal 102 can determine one or more first information based on the first reference signal.

[0129] In some embodiments, the specific type of the first reference signal is not limited, and it is, for example, a Channel State Information Reference Signal (CSI-RS).

[0130] In some embodiments, step 2104 is optional, and the terminal 102 may obtain relevant parameters of the first reference signal through other means.

[0131] Step 2105 : The network device 101 sends fourth information to the terminal 102 .

[0132] In some embodiments, the network device 101 sends fourth information to the terminal 102 to instruct the terminal 102 to send different amounts of first information in different situations, thereby avoiding waste of communication resources.

[0133] In some embodiments, when the network device 101 expects to obtain a first information, or the network device 102 can compensate for the array gain loss of the first beam based on the first information, the fourth information instructs the terminal 102 to send a first information.

[0134] In some embodiments, when the network device 101 expects to obtain multiple first information, or the network device 102 needs to compensate for the array gain loss of the first beam based on multiple first information, the fourth information instructs the terminal 102 to send multiple first information.

[0135] In some embodiments, the fourth information includes at least two reference signal resource unit indexes of the first reference signal, so that the terminal 102 can determine one or more fourth information based on the reference signal resource units indicated by the at least two reference signal resource unit indexes.

[0136] In some embodiments, the number of reference signal resource unit indices of the first reference signal included in the fourth information is related to the number of first information sent by terminal 102 indicated by the fourth information, and terminal 102 can determine one first information through two reference signal resource units of the first reference signal.

[0137] In other words, when the fourth information instructs terminal 102 to send one first information, the fourth information may include reference signal resource unit indexes of two first reference signals. When the fourth information instructs terminal 102 to send multiple first information, the fourth information may include reference signal resource unit indexes of at least three first reference signals.

[0138] In some embodiments, the name of the fourth information is not limited, and may be, for example: "reference signal resource unit indication information", "reference signal resource unit index information", "resource unit index information", etc.

[0139] In some embodiments, step 2105 is optional, and the terminal 102 sends one first message to the network device 101 by default, or the terminal 102 sends multiple first messages to the network device 101 by default.

[0140] Step 2106 : The network device 101 sends the fifth information to the terminal 102 .

[0141] In some embodiments, the network device 101 sends fifth information to the terminal 102 to instruct the terminal on how to determine the first information.

[0142] In some embodiments, the fifth information is used to indicate a manner in which the terminal determines one or more first information.

[0143] In some embodiments, there is no limitation on the method for determining one or more first information, which is, for example: determining the ratio of received energy (Energy per resource element, EPRE) between reference signal resource units of two first reference signals as a first information; for example, determining the normalized value of the ratio between EPREs of reference signal resource units of two first reference signals as a first information. Optionally, the fifth information may also indicate the EPRE of the reference signal resource unit of the first reference signal as a numerator and the EPRE of the reference signal resource unit of the first reference signal as a denominator. For example, the fifth information indicates that the first information is determined by the ratio between the EPRE of reference signal resource unit f1 and the EPRE of reference signal resource unit f2. Then, the fifth information may also indicate the EPRE of reference signal resource unit f1 as the numerator of the ratio and the EPRE of reference signal resource unit f2 as the denominator of the ratio.

[0144] In some embodiments, the fifth information may also indicate the ratio of the reference signal resource units of the two first reference signals.

[0145] In some embodiments, the name of the fifth information is not limited, and it can be, for example: "determination method information", "method indication information", "BSL calculation method information", etc.

[0146] In some embodiments, step 2106 is optional, and the terminal 102 may obtain the fifth information through other devices, or obtain one or more determination methods of the first information based on a protocol agreement.

[0147] In step 2107, the terminal 102 determines a method for determining one or more first information based on the protocol agreement or the fifth information.

[0148] In some embodiments, the terminal 102 may determine a method for determining one or more first information based on a protocol agreement or fifth information.

[0149] In some embodiments, the first information may be determined by determining a ratio between EPREs of reference signal resource units of two first reference signals as the first information.

[0150] In some embodiments, the first information may be determined in a manner that a normalized value of a ratio between EPREs of reference signal resource units of two first reference signals is determined as the first information.

[0151] In some embodiments, the terminal 102 can also determine the numerator and denominator of the ratio between the EPREs of the reference signal resource units based on the protocol agreement or the fifth information, for example: the protocol agreement or the fifth information indicates the EPRE of the reference signal resource unit f1 as the numerator of the ratio, and indicates the EPRE of the reference signal resource unit f2 as the denominator of the ratio, for example: the protocol agreement or the fifth information value indicates the EPRE of the high-frequency reference signal resource unit as the numerator of the ratio, and indicates the EPRE of the low-frequency reference signal resource unit as the denominator of the ratio.

[0152] In some embodiments, step 2107 is optional, and the terminal 102 may default to the method for determining the first information.

[0153] In step 2108, the terminal 102 determines the EPREs of at least two reference signal resource units of the first reference signal based on the protocol agreement or the fourth information.

[0154] In some embodiments, the terminal 102 can determine the reference signal resource unit index of the reference signal resource unit of the first reference signal based on protocol agreement, so that the terminal 102 can measure the corresponding reference signal resource unit based on the above reference signal resource unit index to determine the EPRE of the reference signal resource unit.

[0155] In some embodiments, the terminal 102 may measure the corresponding reference signal resource unit based on the reference signal resource unit index in the fourth information to determine the EPRE of the reference signal resource unit.

[0156] In some embodiments, step 2108 is optional, and the terminal 102 may directly obtain the EPREs of at least two reference signal resource units of the first reference signal.

[0157] In step 2109 , the terminal 102 determines a ratio between EPREs of at least two reference signal resource units based on a protocol agreement or the fifth information.

[0158] In some embodiments, the terminal 102 can determine the EPRE of the reference signal resource unit of the first reference signal as the numerator and the EPRE of the reference signal resource unit of the first reference signal as the denominator based on the protocol agreement or the fifth information, and then determine the ratio between the EPREs of at least two reference signal resource units.

[0159] In some embodiments, step 2109 is optional, and the terminal 102 may obtain the ratio between the EPREs of at least two reference signal resource units through other methods.

[0160] In step 2110 , the terminal 102 determines one or more first information based on a ratio between EPREs of at least two reference signal resource units of a first reference signal.

[0161] In some embodiments, the terminal 102 determines a ratio between EPREs of two reference signal resource units as first information.

[0162] In some embodiments, the terminal 102 may normalize the ratio between the EPREs of the two reference signal resource units to determine the normalized ratio as first information.

[0163] Optionally, the terminal 102 may normalize the ratio between the EPREs of the two reference signal resource units using the following formula:

[0164] Here, η represents the first information (ie, the normalized ratio between the EPREs of the two reference signal resource units), and β represents the ratio between the EPREs of the two reference signal resource units.

[0165] In some embodiments, the terminal 102 may determine multiple ratios between EPREs of at least three reference signal resource units as multiple first information.

[0166] In some embodiments, the terminal 102 may perform normalization processing on multiple ratios between EPREs of at least three reference signal resource units to determine the multiple normalized ratios as multiple first information.

[0167] In some embodiments, step 2110 is optional, and the terminal 102 may directly obtain one or more first information.

[0168] Step 2111 : Terminal 102 sends one or more first information to network device 101 .

[0169] In some embodiments, the terminal 102 sends one or more first information to the network device 101 to report the array gain loss of the first beam to the network device 102, thereby enabling the network device to obtain the beam squint degree of the terminal.

[0170] Optionally, in some embodiments, the first information can also be used to assist the network device 101 in determining whether to compensate for the array gain of the terminal 102. In other words, the network device 101 can comprehensively consider the array gain loss of each terminal 102 based on the first information sent by one or more terminals 102 to determine whether to compensate for the array gain loss of each terminal 102.

[0171] In step 2112, the terminal 102 determines a first threshold based on the third information or the protocol agreement.

[0172] In some embodiments, the terminal may determine the first threshold based on the third information or protocol agreement to determine whether to instruct the network device 101 to compensate for the array gain loss.

[0173] In some embodiments, the first threshold is used to assist the terminal in sending indication information to the network device, where the indication information is used to instruct the network device whether to compensate for array gain loss.

[0174] In some embodiments, the first threshold may be a threshold of a ratio between EPREs of at least two reference signal resource units, or a threshold of a ratio between EPREs of at least two normalized reference signal resource units, which is not limited in the present disclosure.

[0175] In some embodiments, step 2112 is optional, and the terminal 101 itself stores the first threshold.

[0176] In step 2113, the terminal 102 determines the indication information to be sent based on the first threshold and the ratio between the EPREs of at least two reference signal resource units.

[0177] In some embodiments, terminal 102 may determine indication information to send to network device 101 based on a ratio between a first threshold and EPREs of at least two reference signal resource units, so as to instruct network device 101 whether to compensate for array gain loss through the indication information.

[0178] In some embodiments, if the first threshold is greater than the ratio between EPREs of at least two reference signal resource units, the terminal 102 may determine that the indication information sent to the network device 101 is used to instruct the network device 101 to compensate for array gain loss.

[0179] In some embodiments, if the first threshold is less than the ratio between EPREs of at least two reference signal resource units, the terminal 102 may determine that the indication information sent to the network device 101 is used to instruct the network device 101 not to compensate for array gain loss.

[0180] In some embodiments, step 2113 is optional, and the terminal 102 may default to sending the instruction information to the network device 101 to instruct the network device 101 to compensate for the array gain loss.

[0181] In step 2114 , the terminal 102 sends an instruction message to the network device 101 .

[0182] In some embodiments, the terminal 102 sends instruction information to the network device 101 to instruct the network device 101 whether to compensate for array gain loss.

[0183] In some embodiments, the indication information is used to instruct the network device whether to compensate for array gain loss.

[0184] In some embodiments, the name of the indication information is not limited, and may be, for example: "compensation execution information", "compensation indication information", etc.

[0185] In some embodiments, step 2114 is optional, and the network device 101 compensates for array gain loss for the first beam by default.

[0186] In some embodiments, step 2114 is optional, and the network device 101 may comprehensively consider the array gain loss of the terminal 102 based on the received first information to determine whether to compensate the array gain loss for the terminal 102 .

[0187] In step 2115 , the network device 101 determines a first coefficient based on the first information.

[0188] In some embodiments, the network device 101 may determine a first coefficient based on the first information, where the first coefficient is used to compensate for array gain loss of the first beam.

[0189] In some embodiments, the name of the first coefficient is not limited, and it can be, for example, "compensation coefficient", "array gain loss coefficient", "subband precoding coefficient", "delay network coefficient", etc.

[0190] In some embodiments, the specific form of the first coefficient is not limited, and it can be, for example: a compensation coefficient of a delay network, a precoding coefficient of a reference signal resource unit, a compensation coefficient of a phase network, etc.

[0191] In an optional embodiment, each transmitting antenna of the network device 101 has a time delay circuit, that is, the network device 101 has a time delay network. The first coefficient may be a compensation coefficient of the time delay network. The first coefficient may be determined as follows:

[0192] When the adjustment delay on the nth delay device of the network device is: τ n' When , the time domain response of the adjustment delay is: δ(t-τ n' ), the time domain response is a time domain impulse response, and its corresponding frequency domain response is: It can be seen that the frequency domain response corresponding to the time domain response generated by the delay device is a parameter related to the carrier frequency. Therefore, the normalized response for subcarrier fm can be obtained as:

[0193] Among them, the subcarrier f m is the subcarrier of the first beam, N t is the number of antenna elements in the network equipment, w m is the normalized phase shift generated on the mth subcarrier in the frequency domain by adjusting the delay on the nth antenna element.

[0194] The above normalized response (i.e., Equation 2) is in the same form as the network device antenna array response. The network device antenna array response vector is:

[0195] in, λ represents the wavelength of the center carrier frequency, c represents the speed of light, represents a time unit, and θ represents the direction of the above array response is θ.

[0196] The traditional beamforming vector is:

[0197] As can be seen from Equation 4, the beamforming vector expressed in the above equation does not account for the differences in array response between different subcarriers in the first beam in the frequency domain, resulting in a loss of array gain. However, by adding a delay network to the traditional beamforming vector, the delay network can offset the selectivity of the frequency domain response between different subcarriers, thereby adjusting the first beam to point toward θ.

[0198] At the same time, if you want the array gain to be maximum in the θ direction, you need to change τ n'Therefore, the first information reported by the terminal 102 is needed to enable the network device 101 to estimate the location direction of the terminal 102, thereby determining τ n' The changed value is then used to determine the τ of all delay devices in the network equipment. n' The value can be used to determine the compensation coefficient (ie, the first coefficient) of the network device for beam squint.

[0199] In some embodiments, other methods for determining the first coefficient are similar to the above method and are not described again here.

[0200] It should be understood that the above description of the method for determining the first coefficient is only an example and should not limit the present disclosure. The present disclosure does not limit the method for determining the first coefficient and does not limit the specific form of the first coefficient.

[0201] In some embodiments, step 2115 is optional, and the network device 101 may directly obtain the first coefficient.

[0202] In step 2116 , the network device 101 compensates for the array gain loss of the first beam based on the first coefficient, and adjusts the first beam to the target beam direction.

[0203] In some embodiments, the network device 101 may compensate for the array gain loss of the terminal 102 caused by the squint of the first beam based on the first coefficient, and adjust the first beam to the target beam direction to compensate for the array gain loss of the terminal 102 .

[0204] In some embodiments, the target beam direction may be the direction of the actual location of the terminal, the direction of the center carrier frequency configured by the network device for the first beam, etc. The present disclosure does not limit the specific direction referred to by the target beam direction.

[0205] For example, taking the first coefficient as the precoding coefficient of the reference signal resource unit and the target beam direction as the direction of the actual position of the terminal as an example, the network device 101 can adjust the first beam direction to the direction of the actual position of the terminal 102 based on the determined precoding coefficient of the reference signal resource unit to reduce the array gain loss of the terminal 102 and compensate for the array gain loss of the first beam.

[0206] In some embodiments, step 2116 is optional. If the array gain of the terminal 102 is small, the network device 101 may not compensate for the array gain loss of the first beam.

[0207] The communication method according to the embodiments of the present disclosure may include at least one of steps 2101 to 2116. For example, step 2101 may be implemented as an independent embodiment, step 2104 may be implemented as an independent embodiment, steps 2101+2102 may be implemented as an independent embodiment, and steps 2101+2103+2104 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0208] In some embodiments, step 2102, step 2103, step 2104, step 2105 and step 2106 can be performed simultaneously.

[0209] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0519] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0520] The following is an exemplary introduction to the disclosed solution.

[0521] Network device side:

[0522] In some embodiments, the network device can indicate whether the terminal needs to report auxiliary information; the indication information can be indicated in the channel state information (CSI) reporting configuration. For example, a 1-bit indication field is added to the CSI report configuration to indicate the information. When the indication field is 1, no auxiliary information is reported. When the indication field is 0, the indication information is reported.

[0523] In some embodiments, the auxiliary information is a beam squint level (BSL), which is used to describe the magnitude of array gain loss caused by beam squint. For example, one representation of the auxiliary information can be a normalized BSL value in the interval [0, 1].

[0524] In some embodiments, a smaller BSL means a greater array gain loss due to beam squint; a larger BSL means a smaller array gain loss due to beam squint.

[0525] In some embodiments, the network device instructs the terminal how to report the BSL and corresponding configuration information.

[0526] In some embodiments, the terminal has multiple reporting methods, wherein the reporting method can be as follows:

[0527] Method 1: The terminal reports a BSL value, where the BSL calculation method is indicated by the network device or determined by the protocol.

[0528] Method 2: The terminal reports multiple BSL values, where the network device can indicate the calculation method of multiple BSLs, or the calculation method of multiple BSLs can be determined by protocol agreement.

[0529] Method 3: Based on the calculated BSL value and the determined BSL threshold, the terminal reports to the network device whether array gain loss compensation is required. The BSL value calculation method is indicated by the network device or agreed upon by the protocol, and the BSL threshold is indicated by the network device or determined by the protocol.

[0530] In some embodiments, the auxiliary information reported by the network device terminal is used to determine the array gain compensation coefficient, and the array gain compensation coefficient is used to compensate the transmitted beam, for example:

[0531] Method 1: Compensate the transmitted beam by aligning the compensated beam with the beam direction of the center carrier frequency.

[0532] Method 2: Determine the actual location of the terminal based on multiple BSLs, and compensate the transmitted beam by aligning the compensated beam with the actual direction of the terminal.

[0533] Terminal side:

[0534] In some embodiments, the terminal receives reference signal indication information from the network side, performs reference signal measurement according to the reference signal indication information, and calculates the BSL value according to the measurement result.

[0535] In some embodiments, the BSL value is calculated as follows:

[0536] Method 1: Assuming that there are M reference signal resource units in the reference signal CSI-RS, and each reference signal resource unit corresponds to a received energy EPRE, the BSL can be calculated by the above formula 1.

[0537] Method 2: The BSL is directly represented by the EPRE ratio of the two reference signal resource units. In this case, the closer the BSL value is to 1, the smaller the array gain loss due to beam squint, and vice versa.

[0538] In some embodiments, the terminal can also report auxiliary information to the network device to report the magnitude of the array gain loss caused by beam squint.

[0539] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing each step performed by a network device in any of the above methods. For another example, another apparatus is provided that includes units or modules for implementing each step performed by a terminal in any of the above methods.

[0540] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

[0541] In the embodiment of the present disclosure, the processor is a circuit with signal processing capability. In one implementation, the processor can be a circuit with instruction reading and execution capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP); in another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit, and the logical relationship of the above hardware circuit is fixed or reconfigurable, such as a hardware circuit implemented by a processor as an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
