[0095] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0096] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0097] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0098] In some embodiments, network device 102 includes, but is not limited to, at least one of access network device and core network device.

[0099] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0100] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0101] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0102] In some embodiments, the core network equipment may be a single device comprising multiple network elements, or it may be multiple devices or a group of devices, each comprising all or part of the multiple network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0103] In some embodiments, downlink scheduling signaling can be carried by the Physical Downlink Control Channel (PDCCH). The transmission of the PDCCH has the following characteristics and functions:

[0104] 1. Flexible time and frequency resource configuration.

[0105] 2. When the downlink scheduling signaling is downlink control information (DCI), the DCI format is diverse and carries a large amount of control information.

[0106] 3. The search space can include multiple PDCCH candidates and cover multiple aggregation levels, thereby adapting to different channel conditions and reducing the probability of blocking.

[0107] 4. The terminal has a large blind detection load and a high load degree.

[0108] 5. The multiplexing between PDCCH and Physical Downlink Shared Channel (PDSCH) is not flexible enough.

[0109] 6. Network devices need to send a UE-specific PDCCH to each terminal individually in order to schedule unicast data.

[0110] The transmission of PDCCH has the following three elements:

[0111] Element 1, Control Resource Set (CORESET).

[0112] CORESET can be used to determine the physical time-frequency resource distribution of PDCCH transmission.

[0113] Element 2, Search Space (SS).

[0114] Among them, SS can be used to determine the logical resources for PDCCH transmission and can support PDCCH blind detection function.

[0115] Element 3, DCI format.

[0116] The DCI format defines various DCIs with different functions, and different types of control information can be carried in DCIs with different functions.

[0117] In some embodiments, network devices need to send PDCCH frequently, which increases terminal power consumption. Furthermore, CORESET resources may conflict with subband resources. The complex blind detection mechanism of PDCCH also leads to high terminal monitoring complexity and increases terminal power consumption.

[0118] In order to reduce the complexity and load of blind detection of downlink scheduling signaling received by the terminal, and to reduce the power consumption of the terminal, this disclosure provides the following information transmission method, terminal, network device and system, and storage medium.

[0119] Figure 2 is an interactive schematic diagram of an information transmission method according to an embodiment of the present disclosure. As shown in Figure 2, the present disclosure relates to an information transmission method, which includes:

[0120] In step S2101, network device 102 determines the first resource.

[0121] In some embodiments, the first resource is the resource used by the first information. The first information includes second information of the first terminal, which is information related to downlink scheduling signaling.

[0122] In some embodiments, network device 102 may determine the first resource based on a predefined method.

[0123] In one example, the location of the first resource can be agreed upon by the protocol. For example, the first resource can be located in the first time domain unit of each time division multiplexing cycle, and can be located in the first 6 frequency domain units of the downlink bandwidth part (BWP) or downlink subband. For example, the first resource is located in time domain unit #0 and can be located in frequency domain units #0 to #5 of the downlink BWP.

[0124] In one example, the relative position of the first resource with respect to the reference resource can be agreed upon by the protocol. For example, the reference resource can be the resource occupied by the reference signal, and the relative position can be the number of time-domain units and the number of frequency-domain units between the first resource and the reference resource.

[0125] The temporal unit can be a slot, symbol, sub-slot, frame, or subframe.

[0126] The frequency domain unit can be a resource block (RB) or a resource block group (RBG), and this disclosure does not limit it.

[0127] The above is merely an illustrative example, and this disclosure does not limit the scheme by which network device 102 determines the first resource based on a predefined method.

[0128] In some embodiments, network device 102 may configure the first resource for at least one terminal 101 based on scheduling, its own policies, etc.

[0129] In one example, network device 102 configures at least one unoccupied time domain unit and / or at least one frequency domain unit as a first resource before sending downlink scheduling signaling.

[0130] The above is merely an illustrative example, and this disclosure does not limit the scheme for configuring the first resource in network device 102.

[0131] In step S2102, network device 102 sends a first signaling to at least one terminal 101.

[0132] In some embodiments, the first signaling is used to indicate the first resource described above.

[0133] In some embodiments, at least one terminal 101 receives a first signaling.

[0134] In some embodiments, the first signaling may include, but is not limited to, at least one of the following:

[0135] Radio Resource Control (RRC) signaling;

[0136] Downlink Control Information (DCI);

[0137] Media Access Control Element (MAC CE);

[0138] System information (SI), such as system information block n (SIBn), where n is a positive integer.

[0139] In some embodiments, the name of the first signaling is not limited and can be interchanged with resource indication information, resource configuration signaling, etc.

[0140] In some embodiments, step S2102 is an optional execution step. For example, if both network device 102 and terminal 101 determine the first resource based on a predefined method, step S2102 may not be executed.

[0141] Step S2103: The first terminal 101-1 determines the first resource.

[0142] In some embodiments, the first terminal 101-1 may be any one of the above-described at least one terminal.

[0143] In some embodiments, the first terminal 101-1 may determine the first resource based on a predefined method. The specific determination method is similar to the scheme by which the network device 102 determines the first resource based on a predefined method, and will not be described again here.

[0144] In some embodiments, the first terminal 101-1 may determine the first resource based on the first signaling.

[0145] In step S2104, network device 102 sends first information to at least one terminal 101 on the first resource.

[0146] In some embodiments, each of at least one terminal 101 receives the first information on a determined first resource.

[0147] In some embodiments, the first information includes at least one second piece of information, each second piece of information corresponding to a terminal, wherein the second piece of information is information related to downlink scheduling signaling. That is, the first information includes second information corresponding to at least one terminal respectively.

[0148] In some embodiments, the first information may satisfy at least one of the following:

[0149] Modulation is performed using the first modulation method;

[0150] It occupies the first number of time domain units in the time domain;

[0151] It occupies the second number of RBs in the frequency domain.

[0152] In one example, network device 102 may modulate the first information using a first modulation scheme, wherein the first modulation scheme may include, but is not limited to, any of the following:

[0153] Binary Phase Shift Keying (BPSK);

[0154] Quadrature Phase Shift Keying (QPSK);

[0155] 16-ary Quadrature Amplitude Modulation (16QAM);

[0156] 64-ary Quadrature Amplitude Modulation (64QAM).

[0157] For example, considering that binary is frequently used in communication systems, the first modulation method can be BPSK.

[0158] In one example, the first information sent by network device 102 may occupy a first number of time domain units in the time domain. Here, the first number can be represented as M, where M is a positive integer.

[0159] It is understood that the M time-domain units can be continuous or discontinuous, and this disclosure does not impose any restrictions on this.

[0160] In one example, the first information transmitted by network device 102 may occupy a second number of frequency domain units in the frequency domain. This second number can be represented as N, where N is a positive integer.

[0161] It is understood that the N frequency domain units can be continuous or discontinuous, and this disclosure does not limit them.

[0162] In some embodiments, the first information may include P pieces of second information, wherein P can be a positive integer, and the specific value of P can be determined based on a predefined method, such as the P value being directly agreed upon by the protocol, and / or it can be based on the P value indicated by the network device 102. This disclosure does not limit the specific determination method.

[0163] In step S2105, the first terminal 101-1 determines the second information corresponding to the first terminal 101-1 in the first information.

[0164] In some embodiments, the first terminal 101-1 may determine its second information in the following manner:

[0165] Method 1: Determine your own second information based on the second signaling sent by network device 102.

[0166] In one example, network device 102 sends a second signaling to first terminal 101-1, indicating that the information corresponding to the m1-th to m2-th bits in the first information, in left-to-right order, is the second information corresponding to the first terminal 101-1. Here, m1 and m2 can be positive integers.

[0167] For example, suppose the first information has 10 bits, say 11001 00110. In order from left to right, the information 11001 corresponding to the first to fifth bits is the second information corresponding to the first terminal 101-1.

[0168] Method 2: Determine its own second information based on a predefined method.

[0169] In one example, the first terminal 101-1 can determine its corresponding second information according to the Radio Network Temporary Identity (RNTI).

[0170] For example, the protocol stipulates that the second information of each terminal occupies Q bits, where Q is a positive integer. The first information is divided into Q bits, with each Q bit corresponding to an index. The first terminal 101-1 takes the first value modulo its own RNTI, and determines the index of its corresponding second information in the first information based on the remainder, thereby determining its own corresponding second information.

[0171] Assuming the first information has 10 bits and Q is 5, the index of the first 5 bits is 0 and the index of the last 5 bits is 1. The first terminal 101-1 takes the first value modulo its own RNTI. Assuming the remainder is 0, the first terminal 101-1 determines that its corresponding second information is the first 5 bits of the first information.

[0172] This disclosure does not limit the method for determining the first value.

[0173] In one example, the first terminal 101-1 can determine its corresponding second information based on the terminal identifier.

[0174] For example, the protocol stipulates that the second information of each terminal occupies Q bits, where Q is a positive integer. The first information is divided into Q bits, with each Q bit corresponding to an index. The first terminal 101-1 takes the second value modulo its own terminal identifier, and determines its own index in the first information based on the remainder, thereby determining its own corresponding second information.

[0175] Assuming the first information has 10 bits and Q is 5, the index of the first 5 bits is 0 and the index of the last 5 bits is 1, the first terminal 101-1 takes the second value modulo its own terminal identifier. Assuming the remainder is 1, the first terminal 101-1 determines that its corresponding second information is the last 5 bits of the first information.

[0176] This disclosure does not limit the method for determining the second value.

[0177] The above is merely an illustrative example, and this disclosure does not limit the scheme by which the first terminal 101-1 determines its corresponding second information.

[0178] Method 3: Determine its own second information based on the second signaling sent by network device 102 and a predefined method.

[0179] In one example, the second information of each terminal occupies Q bits, the value of which can be agreed upon by the protocol. The first information is divided equally into Q bits, with each Q bit corresponding to an index. Network device 102 instructs the first terminal 101-1 to use a second signaling signal to specify an index. For example, if the index is 0, the terminal will determine the first Q bits of the first information as its corresponding second information.

[0180] In some embodiments, the second information corresponding to the first terminal 101-1 is used to indicate at least one of the following:

[0181] Does the resource grid corresponding to the first terminal 101-1 contain downlink scheduling signaling?

[0182] The size of the resource grid corresponding to the first terminal 101-1;

[0183] The second resource is the resource occupied by the downlink scheduling signaling corresponding to the first terminal 101-1 on the resource grid corresponding to the first terminal 101-1.

[0184] In one example, the resource grid corresponding to the first terminal 101-1 is a resource grid that can be used to transmit downlink scheduling signaling for the first terminal. The resource grid consists of multiple time-frequency resource units. It is understood that multiple terminals can share the same resource grid. Each terminal needs to determine its own corresponding resource grid.

[0185] The resource grid can be measured in units of resource elements (REs), or it can be measured in units of n1 time-domain units and n2 frequency-domain units, where n1 and n2 are positive integers.

[0186] In one example, the second information corresponding to the first terminal 101-1 can be used to indicate whether downlink scheduling signaling corresponding to the first terminal 101-1 exists on the resource grid corresponding to the first terminal 101-1. For example, it can be indicated by one bit, where a bit value of "1" indicates that downlink scheduling signaling corresponding to the first terminal 101-1 exists on the resource grid, and a bit value of "0" indicates that downlink scheduling signaling corresponding to the first terminal 101-1 does not exist on the resource grid.

[0187] In one example, the second information corresponding to the first terminal 101-1 can be used to indicate the size of the resource grid corresponding to the first terminal 101-1.

[0188] For example, a resource grid may include L resource instances (REs), where L can be a positive integer. Secondary information may indicate the value of L.

[0189] In one example, the second information corresponding to the first terminal 101-1 can be used to indicate the specific resource location occupied by the downlink scheduling signaling corresponding to the first terminal 101-1 on the resource grid corresponding to the first terminal 101-1, i.e., the second resource.

[0190] For example, the resource grid includes L REs, and the downlink scheduling signaling corresponding to the first terminal 101-1 occupies the first RE on the resource grid. Then the second information can indicate the index of the second resource.

[0191] The above is merely an illustrative example, and this disclosure does not limit the specific content of the second information indication.

[0192] In step S2106, network device 102 sends downlink scheduling signaling to at least one terminal 101.

[0193] In some embodiments, downlink scheduling signaling may include, but is not limited to, DCI, or other scheduling signaling or scheduling information carried by PDCCH.

[0194] In some embodiments, network device 102 sends downlink scheduling signaling to first terminal 101-1 based on second information corresponding to first terminal 101-1.

[0195] In some embodiments, when the second information corresponding to the first terminal 101 indicates that the downlink scheduling signaling corresponding to the first terminal exists on the resource grid corresponding to the first terminal 101, the network device 102 sends downlink scheduling signaling to the first terminal 101-1. The first terminal 101 receives its own downlink scheduling signaling.

[0196] In some embodiments, when the second information corresponding to the first terminal 101 indicates the size of the resource grid corresponding to the first terminal 101, the network device 102 sends downlink scheduling signaling to the first terminal 101-1 on the resource grid. The first terminal 101 receives its own downlink scheduling signaling on the resource grid.

[0197] In some embodiments, when the second information corresponding to the first terminal 101 indicates the aforementioned second resource, the network device 102 sends downlink scheduling signaling to the first terminal 101-1 on the second resource. The first terminal 101 receives its own downlink scheduling signaling on the second resource.

[0198] In some embodiments, in order to reduce the complexity of terminal blind detection, the second resource for transmitting downlink scheduling signaling and the first resource for transmitting first information can satisfy any of the following in the time domain:

[0199] Located within the same time domain unit;

[0200] The second resource is located after the first resource and is spaced a third number of time domain units apart from the first resource.

[0201] In one example, the second resource may be located in the same time domain unit as the first resource, such as in the same time slot, the same sub-time slot, the same symbol, the same subframe, or the same frame.

[0202] In one example, the second resource may be located in a time-domain cell after the first resource, and the second resource may be spaced a third number of time-domain cells from the first resource.

[0203] The third quantity can be a positive integer, and can be determined based on a predefined method and / or based on the indication of network device 102.

[0204] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0205] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” and “UL DCI” can be used interchangeably.

[0206] In some embodiments, terms such as “moment,” “point in time,” “time,” and “time location” can be used interchangeably, as can terms such as “duration,” “segment,” “time window,” “window,” and “time.”

[0207] In some embodiments, “get,” “obtain,” “receive,” “transmit,” “bidirectional transmission,” and “send and / or receive” can be used interchangeably and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining through self-processing, or autonomous implementation, among other meanings.

[0208] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transmit,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0209] The information transmission method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2106. For example, step S2104 may be implemented as an independent embodiment, step S2105 may be implemented as an independent embodiment, step S2106 may be implemented as an independent embodiment, step S2104+S2105+S2106 may be implemented as an independent embodiment, step S2101+S2103 may be implemented as an independent embodiment, step S2102+S2103 may be implemented as an independent embodiment, and steps S2101 to S2106 may be implemented as independent embodiments, but are not limited thereto.

[0210] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, when both terminal 101 and network device determine the first resource based on a predefined method, step S2102 may not be executed.

[0211] In some embodiments, step S2105 is optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, if the first information only includes the second information corresponding to the first terminal, then step S2105 may not be executed.

[0212] In some embodiments, steps S2101 to S2106 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0213] In some embodiments, the execution order of steps S2101 to S2106 is not limited.

[0214] In the above embodiments, the first terminal can receive first information sent by the network device on the first resource. The first information includes second information of at least one terminal. The first terminal determines its own corresponding second information from the first information and receives downlink scheduling signaling sent by the network device based on the determined second information. This reduces the blind detection complexity and load of the terminal receiving downlink scheduling signaling, reduces terminal power consumption, and improves availability.

[0278] Figure 3D is a flowchart illustrating an information transmission method according to an embodiment of the present disclosure. As shown in Figure 3D, this disclosure relates to an information transmission method, which is executed by a network device 102, and includes:

[0279] Step S3401: Send the first message.

[0280] In some embodiments, the first information includes second information of the first terminal, wherein the second information is information related to downlink scheduling signaling.

[0281] In some embodiments, network device 102 sends first information to at least one terminal 101.

[0282] In some embodiments, at least one terminal 101 receives first information.

[0283] In some embodiments, optional implementations of step S3401 can be found in optional implementations of step S2104 in FIG2 and other related parts in the embodiments involved in FIG2, which will not be repeated here.

[0284] The above embodiments reduce the blind detection complexity of the terminal receiving downlink scheduling signaling.

[0285] The above process is further illustrated with examples below.

[0286] In this embodiment of the disclosure, taking downlink scheduling signaling as downlink scheduling information (DCI) as an example, the terminal can detect and receive downlink control information on fixed time and frequency resources, and obtain data channel transmission information on the corresponding time and frequency resource grid according to the instructions of the downlink control information.

[0287] Terminal side:

[0288] On fixed time-frequency resources, detect the transmission time-frequency resource grid information carried by the received downlink control information, and obtain relevant information about data channel transmission on the corresponding time-frequency resource grid:

[0289] Step 1, the first fixed time-frequency resource location of the time-frequency resource grid used to send downlink control information, is configured by explicit signaling sent through the network or determined according to a predefined method of the protocol.

[0290] The fixed time-frequency resources are used to transmit relevant information from multiple terminals.

[0291] The different terminals determine their corresponding time-frequency resource locations based on the base station's indication signaling and / or predefined rules.

[0292] The channel transmitted at the aforementioned time-frequency resource location is transmitted via BPSK, occupying N OFDM symbols in the time domain and M PRBs in the frequency domain. This patent does not limit whether the time-domain resources and / or frequency-domain resources are continuous.

[0293] Step 2: Transmit the second time-frequency resource grid information of P terminals on the first fixed time-frequency resource.

[0294] The location of the corresponding information of the P terminals is determined through network configuration or predefined methods (RNTI or terminal identifier).

[0295] The information corresponding to the terminal includes a Q bit, which is used to indicate at least whether the terminal's scheduling information exists at its corresponding position on the second video resource grid, and the size of the second time-frequency resource grid.

[0296] Step 3: The terminal receives the instruction information (i.e. downlink scheduling information) for scheduling at the specific time-frequency resource location determined by the second time-frequency resource grid, as instructed by the base station.

[0297] For example, the indication information determined by the second time-frequency resource grid is located in the same slot as the first time-frequency resource, or there is a fixed timing relationship between the two.

[0298] Base station side:

[0299] Step 1: Send the transmission time-frequency resource grid information carried by the downlink control information on the fixed time-frequency resources, and obtain the relevant information of data channel transmission on the corresponding time-frequency resource grid.

[0300] The first fixed time-frequency resource location used to transmit downlink control information is configured by explicit signaling sent through the network or determined according to a predefined protocol.

[0301] The fixed time-frequency resources are used to transmit relevant information from multiple terminals.

[0302] The different terminals determine their corresponding time-frequency resource locations based on the base station's indication signaling and / or predefined rules.

[0303] The channel transmitted at the aforementioned time-frequency resource location is transmitted via BPSK, occupying N OFDM symbols in the time domain and M PRBs in the frequency domain. This patent does not limit whether the time-domain resources and / or frequency-domain resources are continuous.

[0304] Step 2: Transmit the second time-frequency resource grid information of P terminals on the first fixed time-frequency resource.

[0305] The location of the corresponding information of the P terminals is determined through network configuration or predefined methods (RNTI or terminal identifier).

[0306] The information corresponding to the terminal includes a Q bit, which is used to indicate at least whether the terminal's scheduling information exists at its corresponding position on the second video resource grid, and the size of the second time-frequency resource grid.

[0307] Step 3: The base station sends scheduling indication information at a specific time-frequency resource location determined by the second time-frequency resource grid.

[0308] For example, the indication information determined by the second time-frequency resource grid is located in the same slot as the first time-frequency resource, or there is a fixed timing relationship between the two.

[0309] For example, as shown in Figure 4, the first information transmitted on the first resource may include the second information of terminals #1 to #4. Based on its own second information, terminal #1 receives its own corresponding downlink scheduling signaling on the second resource #1. Based on its own second information, terminal #2 receives its own corresponding downlink scheduling signaling on the second resource #2, and so on.

[0310] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0311] This disclosure also provides embodiments of an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is provided that includes units or modules for implementing the steps performed by the network device in any of the above methods.

[0312] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0313] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, 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).

The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using 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 configuring the hardware circuit 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 hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Units (NPUs), Tensor Processing Units (TPUs), and Deep Learning Processing Units (DPUs).
