[0106] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Futuregeneration radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).
[0107] In some embodiments, the DCI format introduced in 5G and its application scenarios can be as shown in Table 1: Table 1 In some embodiments, the introduction of multiple format DCIs enables flexible resource scheduling. However, since different format DCIs may correspond to different DCI sizes, the increase in blind detection DCI size increases the blind detection overhead of the terminal. In addition, in order to meet the "3+1" limit of DCI size, different format DCIs may need to be aligned in terms of DCI size by adding zero bits, which leads to an increase in DCI size and a corresponding decrease in the transmission performance of the Physical Downlink Control Channel (PDCCH).
[0108] In future versions, such as 6G, if the 5G approach is still used to implement data scheduling for different communication scenarios by introducing more DCI formats, the number of DCI formats will increase significantly, thereby further increasing the complexity of terminal blind detection and reducing the corresponding PDCCH transmission performance.
[0109] To mitigate the aforementioned negative impacts, future versions, such as 6G, could consider adopting a two-stage downlink control information (DCI) design. For example... Figure 1B As shown, the first-stage DCI can carry scheduling information for PDSCH and PUSCH, such as the transmission location of Hybrid Automatic Repeat Request-Acknowledge (HARQ-ACK). For example... Figure 1C As shown, the 1st DCI can directly carry the transmission resources of the second-stage DCI (2nd DCI).
[0110] The first stage DCI can adopt a unified design and carry scheduling information related to the second stage DCI.
[0111] One possible implementation involves the terminal blindly detecting the first-level DCI to obtain the information carried by it. The first-level DCI carries the transmission information of the second-level DCI, and the second-level DCI can carry different content based on different scheduling information. Since the second-level DCI does not require blind detection, the terminal's blind detection complexity is effectively reduced. Furthermore, if the first-level DCI adopts a unified design, such as being carried based on a single DCI format, the number of DCI formats that the terminal needs to blindly detect can be effectively reduced, thereby significantly reducing the blind detection overhead of the PDCCH.
[0112] As described above, unlike related technologies where the terminal blindly detects DCI using candidate PDCCH blind detection resources, the second DCI in the aforementioned two-stage DCI can be determined through signaling indication, for example, through the first DCI. In related mechanisms, the terminal blindly detects the corresponding DCI based on the search space (SS) corresponding to the PDCCH. Considering that the second DCI can be indicated by the first DCI signaling without blind detection, this can be used to determine the transmission information of the second DCI.
[0113] In some embodiments, the number of Service Controllers (SSs) that a terminal can configure on a single Bandwidth Part (BWP) corresponding to a single serving cell cannot exceed 10. The Information Element (IE) of the corresponding SS is mainly used to define the method and temporal location of blind detection PDCCH candidates. An SS is associated with a Control Resource Set (CORESET). In cross-carrier scheduling scenarios, the SS of the scheduled cell is only configured with a searchspace identifier (searchSpaceId) and the number of PDCCH candidates (nrofCandidates).
[0114] The corresponding SearchSpace IE includes at least one of the following: searchSpaceId ( Specifically, SS#0 is configured based on the Master Indication Block (MIB) and / or Serving Cell Config Common (ServingCellConfigCommon) configuration, not through the aforementioned IE configuration. For the same serving cell, the SearchSpace ID corresponding to different BWPs is unique. In cross-carrier scheduling (CCS) scenarios, the SSs corresponding to the same SearchSpace ID in the scheduling cell and the scheduled cell have a link relationship. The SS only takes effect when the downlink (DL) BWPs corresponding to the SSs of both the scheduling cell and the scheduled cell are in an active state. Control Resource Set Identifier (controlResourceSetId): Indicates the control resource set identifier associated with searchspace s; PDCCH Blind Detection Period and Slot Offset (monitoringSlotPeriodicityAndOffset): Indicates the period and slot offset of the blind detection candidate PDCCH.
[0115] The PDCCH candidate symbols (monitoring symbolsWithinSlot) include the starting symbol and the number of persistent symbols for each PDCCH candidate, where the number of persistent symbols equals the number of persistent symbols in the CORESET. DCI format 2_0 schedules only the first three symbols.
[0116] Duration: Indicates the number of slots that the SS persists in within a period. The situation where the SS persists in multiple slots is mainly related to the blind detection window of the Random Access Response (RAR). PDCCH candidate count (nrofcandidates): The number of PDCCH candidates corresponding to different AL configurations. ; Search Space Type: Common Search Space (CSS) or User-Specific Search Space (USS); If the SS is CSS, the configurable DCI format of the SS includes at least one DCI format corresponding to the CSS; If the SS is a USS, the configurable DCI format of the SS includes at least one DCI format corresponding to the USS; In the relevant mechanism, the candidate resources of PDCCH that the terminal can transmit are based on the PDCCH candidate definition. The PDCCH candidate corresponds to the aggregation level (AL). For a specific PDCCH candidate, the control channel element (CCE) resource to which it belongs is determined in the following way: If the terminal configures a search space on the activated downlink BWP With CORESET Related to the scheduled cell In terms of time slots, the aforementioned search space... Configured corresponding aggregation level PDCCH candidate The corresponding CCE index is determined based on the following formula 1: Formula 1 The parameters in the above formula are determined based on the following method: in, ; CSS USS , ,for , ,for , ,for , , The nRNTI is the C-RNTI value configured for the terminal, and the C-RNTI is configured for each terminal. The terminal attempts to decode based on the configured C-RNTI. If the decoding is successful, the terminal can receive the DCI sent by the base station. For CORESET The number of continuous CCEs, and the corresponding CCE index are arranged in ascending order (0, ..., ...). ); Configure the carrier indicator field (CIF) value for the terminal based on the CrossCarrierSchedulingConfig configuration. In CrossCarrierScheduling (CCS) scenarios, the terminal determines whether a specific cell is scheduled by the scheduling cell based on this configuration. ; , in, For the dispatched cell The search space configured above Internal corresponding aggregation level The number of configured PDCCH candidates. It's worth noting that for configuration... The scheduled cell, its SS configuration only contains searchspaceid= The two searchspace IDs, nrofcandidates and nrofcandidates, are linked and have the same searchspace ID configured on the scheduling cell for that cell. For example, they are linked. Figure 1D As shown. Configuration The scheduled cell is configured with an SS with a link relationship, which is mainly used to configure the number of blind detection PDCCH candidates used to schedule the scheduled cell.

[0119] To reduce the complexity of blind detection at the terminal, this disclosure provides the following information transmission method, terminal, network device, system, and storage medium.
[0120] Figure 2 This is an interactive schematic diagram illustrating an information transmission method according to an embodiment of this disclosure. For example... Figure 2 As shown, the embodiments of this disclosure relate to an information transmission method, which includes: In step S2101, network device 102 sends the first DCI and configuration to terminal 101.
[0121] In some embodiments, terminal 101 receives a first DCI.
[0122] In some embodiments, the first DCI may be associated with the second DCI.
[0123] In one example, the association of a first DCI with a second DCI could mean that the first DCI can be used to determine the transport resources of the second DCI.
[0124] For example, the first DCI can be used to determine the PDCCH resource corresponding to the second DCI.
[0125] In one example, the association between the first DCI and the second DCI can mean that terminal 101 can detect the reception of the second DCI by detecting the reception of the first DCI.
[0126] In one example, the first DCI can be the first stage DCI in a two-stage DCI, and the second DCI can be the second stage DCI in a two-stage DCI; this disclosure does not limit this.
[0127] In some embodiments, the first DCI may be the DCI corresponding to the USS or the DCI corresponding to the CSS, and this disclosure does not limit it.
[0128] In some embodiments, the second DCI may be the DCI corresponding to the USS or the DCI corresponding to the CSS, and this disclosure does not limit it.
[0129] In some embodiments, the first DCI may be used to indicate at least one of the following: at least one aggregation level AL corresponding to the physical downlink control channel (PDCCH) resource; at least one sub-resource index corresponding to the PDCCH resource; and a mapping relationship between the PDCCH resource and each sub-resource in the PDCCH resource.
[0130] In one example, the PDCCH resource is the PDCCH resource corresponding to the second DCI.
[0131] In one example, the first DCI can indicate an AL corresponding to the PDCCH resource, and / or a sub-resource index corresponding to the PDCCH resource. For instance, the sub-resource index can be a candidate PDCCH index corresponding to the AL.
[0132] In one example, the first DCI may indicate at least one of the following: multiple ALs corresponding to the PDCCH resource; multiple sub-resource indices corresponding to the PDCCH resource; and the mapping relationship between the PDCCH resource and each sub-resource in the PDCCH resource.
[0133] Each sub-resource index can be a candidate PDCCH index corresponding to an AL. This mapping relationship can be used to determine the cascading relationship between sub-resources; multiple sub-resources are cascaded to obtain the PDCCH resource corresponding to the second DCI.
[0134] In some embodiments, terminal 101 receives the configuration.
[0135] In some embodiments, the configuration may be a second configuration, wherein the second configuration is associated with a second DCI.
[0136] In one example, the association of the second configuration with the second DCI could mean that the second configuration is used to provide information related to the transmission of the second DCI. For example, the second configuration could be used to determine the transmission resources of the second DCI.
[0137] In one example, the second configuration can be provided to the terminal via signaling, which may be Radio Resource Control (RRC) signaling, and this disclosure is not limited thereto.
[0138] In one example, the second configuration could be, for example, the second SS configuration, i.e., the configuration of the SS used to configure the second DCI.
[0139] In some embodiments, the configuration may be a first configuration, wherein the first configuration is associated with a first DCI.
[0140] In one example, associating the first configuration with the first DCI could mean that the first configuration is used to provide information related to the transmission of the first DCI. For example, the first configuration could be used to determine the transmission resources of the first DCI.
[0141] In one example, the first configuration can be provided to the terminal via signaling, which may be RRC signaling, and this disclosure does not limit this.
[0142] In one example, the first configuration could be, for example, the first SS configuration, i.e., the configuration of the SS used to configure the first DCI.
[0143] In some embodiments, the name of the configuration is not limited and can be interchanged with "signaling configuration", "search space configuration", etc.
[0144] In some embodiments, network device 102 may send a first DCI and configuration to terminal 101 in cross-carrier scheduling scenarios or other scenarios.
[0145] In some embodiments, network device 102 may send a first DCI and configuration to terminal 101 when it is necessary to reduce the complexity of terminal blind detection.
[0146] In some embodiments, network device 102 may send a first DCI and configuration to terminal 101 based on a request from terminal 101.
[0147] In some embodiments, network device 102 may send a first DCI and configuration to terminal 101 if it is determined that the terminal's battery level is below a threshold.
[0148] The above is merely an illustrative example, and this disclosure does not limit the timing or event that triggers network device 102 to send the first DCI and configuration to terminal 101.
[0149] In step S2102, terminal 101 determines that the configuration is the second configuration.
[0150] In some embodiments, terminal 101 may determine, based on a predefined method, that the configuration sent by network device 102 is the second configuration.
[0151] In one example, if the identifier in the configuration can be used for the second configuration, then terminal 101 determines that the configuration is the second configuration.
[0152] For example, a specific set of identifiers can be defined for the second configuration, and the identifiers in this set are used only for the second configuration. After receiving the configuration sent by the network device 102, if the terminal 101 determines that the identifiers in the configuration belong to the specific set of identifiers, it can determine that the configuration is the second configuration.
[0153] For example, if the SS identifier in the SS configuration corresponds to the second SS configuration according to the protocol, and the SS identifier in the SS configuration belongs to the SS identifier set #2, then the terminal 101 can determine that the SS configuration is the second SS configuration.
[0154] It is understandable that if the identifier in the configuration can be used for the first configuration and / or cannot be used for the second configuration, then terminal 101 determines that the configuration is the first configuration.
[0155] For example, if the SS identifier set #2 is agreed upon by the protocol and corresponds to the second SS configuration, and the SS identifier in the SS configuration does not belong to the SS identifier set #2, then the terminal 101 can determine that the SS configuration is the first SS configuration.
[0156] For example, the protocol specifies an SS identifier set #1 corresponding to the first SS configuration and an SS identifier set #2 corresponding to the second SS configuration. After receiving the SS configuration sent by the network device, if the SS identifier in the SS configuration belongs to the SS identifier set #1, then the terminal 101 can determine that the SS configuration is the first SS configuration.
[0157] In one example, the configuration includes the DCI format corresponding to the second DCI, thus confirming that the configuration is the second configuration.
[0158] For example, the DCI format specific to the second DCI can be agreed upon by the protocol. If the configuration specifies the DCI format specific to the second DCI, the terminal 101 can determine that the configuration is the second configuration.
[0159] It is understandable that if the configuration includes the DCI format corresponding to the first DCI and / or the configuration does not include the DCI format corresponding to the second DCI, then the terminal 101 determines that the configuration is the first configuration.
[0160] The above is merely an illustrative example, and this disclosure does not limit the method by which the terminal determines that the configuration is the second configuration based on a predefined method.
[0161] In some embodiments, terminal 101 may determine that the configuration sent by network device 102 is the second configuration based on the indication information sent by network device 102.
[0162] In one example, this information can be used to indicate the type of configuration.
[0163] For example, this instruction information can be carried in the configuration and provided to terminal 101.
[0164] For example, network device 102 introduces a specific field in its configuration that can be used to indicate the type of configuration, such as a second configuration.
[0165] It is understandable that if the configuration does not include the field used to indicate the type of configuration, or if the field used to indicate the type of configuration in the configuration indicates that the configuration is the first configuration, then terminal 101 can determine that the configuration is the first configuration.
[0166] In some embodiments, terminal 101 may determine that the configuration sent by network device 102 is the second configuration based on a predefined method and the indication information sent by network device 102.
[0167] The above is merely an illustrative example, and this disclosure does not limit the method by which terminal 101 determines whether the configuration is the second configuration or the first configuration.
[0168] In some embodiments, the second configuration is used to configure at least one of the following: an identifier of the second configuration; an identifier of a first configuration associated with the first DCI; an identifier of a control resource set associated with the second configuration; a time-domain resource offset, which indicates the offset of the time-domain resources of the second DCI relative to the time-domain resources of the first DCI; a sub-time unit in which the physical downlink control channel (PDCCH) is located within a time unit; the maximum number of sub-resources corresponding to the aggregation level (AL); AL; and the DCI format.
[0169] Where the second configuration includes the identifier of the first configuration, the first configuration is associated with the second configuration. The first configuration is associated with the first DCI.
[0170] The time unit can be a slot, a sub-slot, a symbol, a frame, a subframe, etc.
[0171] In the case where the second configuration does not include a time domain resource offset or the time domain resource offset is 0, the second DCI and the first DCI are transmitted on the same time domain resource.
[0172] The second configuration may include one or more specific ALs.
[0173] For example, the maximum number of sub-resources corresponding to the AL configured in the second configuration can be represented by the maximum number of candidate PDCCHs corresponding to that AL.
[0174] The DCI format can be the format of a second DCI. For example, the second configuration may include the DCI format of the second DCI.
[0175] The above is merely an illustrative example, and this disclosure does not limit the content configured in the second configuration.
[0176] In some embodiments, the content configured by the first configuration may be similar to the content configured by the second configuration. For example, the first configuration may be used to configure at least one of the following: an identifier of the second configuration; an identifier of the first configuration; an identifier of the control resource set associated with the first configuration; a time-domain resource offset, which is used to indicate the offset of the time-domain resources of the second DCI relative to the time-domain resources of the first DCI; the sub-time unit where the PDCCH is located within a time unit; the maximum number of sub-resources corresponding to the AL; the AL; and the DCI format (the DCI format is the format of the first DCI).
[0177] The above is merely an illustrative example, and the contents configured in the two configurations may also be different; this disclosure does not limit this.
[0178] In some embodiments, the second configuration may be a configuration for configuring the search space of the second DCI, or the second configuration may be a configuration specifically for configuring the transmission resources of the second DCI, which is not limited in this disclosure.
[0179] In some embodiments, the second configuration may be other configurations, such as, but not limited to, the CORESET configuration associated with the second DCI, the AL configuration, the sub-resource index configuration, etc. In one example, the second configuration may be replaced with "the nth configuration", and this disclosure does not limit it in this way.
[0180] Similarly, the first configuration can be a configuration for configuring the search space of the first DCI, or the first configuration can be other configurations, such as, but not limited to, the CORESET configuration, AL configuration, sub-resource index configuration, etc. associated with the first DCI. In one example, the first configuration can be replaced with "the nth configuration", and this disclosure does not limit it in this way.
[0181] In step S2103, terminal 101 determines the first configuration associated with the second configuration.
[0182] In some embodiments, terminal 101 may determine the first configuration associated with the second configuration based on a predefined method.
[0183] In one example, terminal 101 can determine the first configuration associated with the second configuration based on the configuration identifier.
[0184] For example, terminal 101 may identify a first configuration that has the same identifier as the second configuration as the first configuration associated with the second configuration.
[0185] For example, if the second configuration includes second configuration #1 and second configuration #2, and the first configuration includes first configuration #1 and first configuration #2, then the terminal 101 can determine that the first configuration associated with the second configuration #1 is the first configuration #1, and the first configuration associated with the second configuration #2 is the first configuration #2.
[0186] In one example, terminal 101 may determine a first configuration that corresponds to the same time unit as the second configuration as the first configuration associated with the second configuration.
[0187] For example, the second configuration may correspond to a different identifier than the first configuration.
[0188] For example, the second configuration corresponding to the same time unit as the first configuration can refer to the two configurations corresponding to the same monitoring occupancy (MO).
[0189] For example, the time units corresponding to the second configuration and the first configuration can mean that the time units corresponding to the two configurations are exactly the same, or that the time units corresponding to the second configuration are a subset of the time units corresponding to the first configuration, or that the time units corresponding to the first configuration are a subset of the time units corresponding to the second configuration. Alternatively, the time units corresponding to the first configuration and the time units corresponding to the second configuration may partially overlap.
[0190] For example, the second configuration corresponds to the same MO as the first configuration, or the MO corresponding to the second configuration is a subset of the MO corresponding to the first configuration, or the MO corresponding to the first configuration is a subset of the MO corresponding to the second configuration. In this case, terminal 101 can determine that the first configuration and the second configuration are associated.
[0191] For example, if the MO corresponding to the second configuration #1 is {MO#1, MO#3, MO#4}, the MO corresponding to the first configuration #1 is MO#2, the MO corresponding to the first configuration #2 is MO#5, and the MO corresponding to the first configuration #3 is MO#3, then the terminal 101 can determine that the first configuration #3 is the first configuration associated with the second configuration #1. At this time, the terminal 101 can determine that the first configuration is associated with the second configuration.
[0192] For example, if the MO#1 corresponding to the second configuration occupies symbols #0 to #2 of time slot #1, and the MO#2 corresponding to the first configuration occupies symbols #0 to #1 of time slot #1, and the two have some overlap in the time domain, then the terminal 101 can determine that the first configuration is associated with the second configuration.
[0193] In some embodiments, terminal 101 may determine the first configuration associated with the second configuration based on the first signaling sent by network device 102.
[0194] In one example, the first signaling may be used for at least one of the following: configuring an identifier of a first configuration associated with the second configuration in the second configuration; configuring an identifier of a second configuration associated with the first configuration in the first configuration.
[0195] In one example, the first signaling can be at least one of the following: System Information Block (SIB); RRC signaling; Media Access Control - Control Element (MAC CE); DCI.
[0196] In some embodiments, terminal 101 may determine the first configuration associated with the second configuration based on a predefined method and the first signaling sent by network device 102.
[0197] In one example, the protocol may stipulate at least two ways to determine the first configuration associated with the second configuration, such as whether the configuration identifiers are the same or whether the corresponding time units are the same. The network device 102 instructs the terminal 101 to use one of these methods via the first signaling.
[0198] The above is merely an illustrative example, and this disclosure does not limit the method by which terminal 101 determines the first configuration associated with the second configuration.
[0199] In step S2104, terminal 101 determines the transmission resources of the second DCI.
[0200] In some embodiments, the terminal 101 may determine the time domain resources of the first DCI as the time domain resources of the second DCI, that is, the second DCI and the first DCI are transmitted on the same time domain resources.
[0201] In one example, the second DCI occupies the exact same time-domain resources as the first DCI. For instance, the first DCI occupies symbols #0 to #2 in time slot #1, and the second DCI also occupies symbols #0 to #2 in time slot #1.
[0202] In one example, the time domain resources occupied by the second DCI partially overlap with those occupied by the first DCI. For example, the first DCI occupies symbols #0 to #2 in time slot #1, and the second DCI occupies symbols #0 to #1 in time slot #1.
[0203] In one example, terminal 101 can determine the time domain resources of the first DCI as the time domain resources of the second DCI if the second configuration does not configure the time domain resource offset.
[0204] In some embodiments, terminal 101 may determine the time domain resources of the second DCI based on the time domain resource offset configured in the second configuration and the time domain resources of the first DCI.
[0205] For example, when the time-domain resource offset is positive, the second DCI is determined to be later than the first DCI in the time domain. When the time-domain resource offset is negative, the second DCI is determined to be earlier than the first DCI in the time domain.
[0206] Terminal 101 can offset the time domain resources occupied by the first DCI based on the time domain resource offset configured in the second configuration to obtain the time domain resources of the second DCI.
[0207] In some embodiments, terminal 101 may determine the transmission resources of the second DCI based on the first DCI and the second configuration.
[0208] In one example, terminal 101 can determine the frequency domain resources of the second DCI based on the indication of the first DCI and the second configuration.
[0209] In one example, terminal 101 determines the frequency domain resources of the second DCI based on the indication of the first DCI, specifically including determining the PDCCH resources corresponding to the second DCI.
[0210] In one example, the first DCI can indicate an AL corresponding to the PDCCH resource, and / or a sub-resource index corresponding to the PDCCH resource. The sub-resource index can be a candidate PDCCH index corresponding to the AL.
[0211] In one example, the first DCI may indicate at least one of the following: multiple ALs corresponding to the PDCCH resource; multiple sub-resource indices corresponding to the PDCCH resource; and the mapping relationship between the PDCCH resource and each sub-resource in the PDCCH resource.
[0212] Each sub-resource index can be a candidate PDCCH index corresponding to an AL. This mapping relationship can be used to determine the cascading relationship between sub-resources; multiple sub-resources are cascaded to obtain the PDCCH resource corresponding to the second DCI.
[0213] For example, terminal 101 may determine the mapping relationship based on the indication of the first DCI.
[0214] For example, terminal 101 can determine the mapping relationship based on a predefined method.
[0215] Where the mapping relationship is to first map the first sub-resource and then map the second sub-resource, the mapping relationship may specifically include, but is not limited to, at least one of the following: the number of frequency domain resources included in the first sub-resource is less than the number of frequency domain resources included in the second sub-resource; the number of frequency domain resources included in the first sub-resource is greater than the number of frequency domain resources included in the second sub-resource; the lowest frequency domain position of the first sub-resource is lower than the lowest frequency domain position of the second sub-resource; the lowest frequency domain position of the first sub-resource is higher than the lowest frequency domain position of the second sub-resource; the first sub-resource and the second sub-resource do not overlap in the frequency domain; the interval between the first sub-resource and the second sub-resource in the frequency domain is minimized; the first sub-resource and the second sub-resource are associated.
[0216] The number of frequency domain resources can be at least one of the following: the number of resource blocks (RBs), the number of resource block groups (RBGs), the number of CCEs, resource elements (REs), and bound resource element group bundles (REG bundles), and this disclosure does not limit it.
[0217] It is understandable that after determining the AL and the candidate PDCCH index corresponding to the AL, or determining multiple ALs, the candidate PDCCH index corresponding to each AL, and the mapping relationship, the location of the PDCCH resource can be determined.
[0218] For example Figure 1E As shown, if AL is 1 and the candidate PDCCH index is 0, then terminal 101 can determine CCE#0 as the location of the PDCCH resource.
[0219] For example Figure 1E As shown, AL is 1 and 2, and the corresponding candidate PDCCH indices are 1 and 0 respectively. The mapping relationship is that the number of frequency domain resources included in the first sub-resource is greater than the number of frequency domain resources included in the second sub-resource. Therefore, the terminal 101 can determine to first map the sub-resource corresponding to AL=2 and then map the sub-resource corresponding to AL=1. Thus, the terminal 101 can determine CCE#0, CCE#1 and CCE#2 as the positions of PDCCH resources.
[0220] In one example, if the search space of the second DCI is not configured in the second configuration, the terminal 101 can determine the SS corresponding to the first DCI as the SS corresponding to the second DCI. If the search space of the second DCI is configured in the second configuration, the terminal determines the search space of the second DCI based on the second configuration.
[0221] In addition, terminal 101 can also determine the time domain resources occupied by the first DCI as the time domain resources occupied by the second DCI.
[0222] In some embodiments, terminal 101 determines that the second DCI and the first DCI are transmitted on different time-domain resources.
[0223] In one example, the temporal resources of the second DCI are offset relative to the temporal resources of the first DCI; this offset can be referred to as the temporal resource offset.
[0224] For example, the time-domain resource offset can be indicated by a first DCI and / or a second configuration.
[0225] For example, terminal 101 can determine the time domain resource offset based on a predefined method.
[0226] For example, when the time-domain resource offset is positive, the second DCI is determined to be later than the first DCI in the time domain. When the time-domain resource offset is negative, the second DCI is determined to be earlier than the first DCI in the time domain.
[0227] For example, the second DCI is transmitted in the Nth time unit after the first DCI transmits the MO, where N is indicated by indication signaling, for example, through the first DCI and / or the second configuration indication. Alternatively, N is determined based on a predefined method.
[0228] For example, a list of time-domain resource offsets can be configured via higher-level signaling, and further, via an offset from a first DCI and / or a second configuration instruction list.
[0229] The above is merely an illustrative example. This disclosure does not limit the method by which the terminal 101 determines the time domain resources of the second DCI based on the time domain resources of the first DCI.
[0230] In some embodiments, in addition to determining the time-frequency domain resources of the second DCI, the terminal 101 can also determine the spatial domain resources of the second DCI, such as determining the second beam, which is the beam corresponding to the second DCI.
[0231] In one example, terminal 101 can determine the second beam based on a predefined method.
[0232] For example, the second beam is the same beam as the first beam, and the first beam is the beam corresponding to the first DCI.
[0233] In one example, terminal 101 can determine the second beam based on the second signaling sent by network device 102.
[0234] For example, the second signaling may indicate the index of a beam configured by the network device.
[0235] For example, terminal 101 can determine a beam list based on higher-layer signaling, such as RRC signaling, system information, MAC CE, etc. Further, terminal 101 can determine a beam indicated by a network device in the beam list based on a second signaling.
[0236] For example, the second signaling can be MAC CE, DCI, etc., and this disclosure is not limited thereto.
[0237] For example, if the beam indicated by the second signaling is a different beam from the first beam, then the terminal 101 can ignore the second signaling and directly determine the first beam as the second beam, where the first beam is the beam corresponding to the first DCI.
[0238] It is understandable that the first DCI and the second DCI occupy the same time domain resources. During beam scanning, the same time domain resources generally correspond to the same beam. That is, in this disclosure, a more reasonable approach is for the two DCIs to use the same beam for transmission. Therefore, the terminal 101 can ignore the indication of the second signaling when the beam indicated by the second signaling is different from the first beam, and still determine the first beam corresponding to the first DCI as the second beam corresponding to the second DCI.
[0239] For example, the beam indicated by the second signaling is a different beam from the first beam. In order to ensure the reliability of network device scheduling, the terminal 101 can determine the beam indicated by the second signaling as the second beam based on the scheduling of the network device 102.
[0240] In some embodiments, terminal 101 may also determine the transmission resources of the second DCI based on a predefined method.
[0241] In one example, the second DCI and the first DCI can be used together to schedule the same information. In this case, it can be determined that the second DCI and the first DCI occupy the same time domain resources and the same search space.
[0242] In one example, the protocol may stipulate that the second DCI is located after the first DCI and adjacent to the first DCI in the time domain, occupying multiple consecutive symbols. Alternatively, the second DCI may occupy the first n symbols of the next time slot after the first DCI, where n can be 1, 2, 3, or other positive integer values, and this disclosure does not limit this.
[0243] In one example, the frequency domain offset of the second DCI relative to the first DCI can be determined based on a predefined method.
[0244] For example, the offset of a specific frequency domain position of the second DCI relative to a specific frequency domain position of the first DCI may be agreed upon by the protocol. The specific frequency domain position may be the lowest frequency domain position, the highest frequency domain position, the intermediate frequency point position, etc., and this disclosure does not limit it.
[0245] For example, the protocol can stipulate that if the second DCI and the first DCI occupy different time domain resources, they can occupy the same frequency domain resources.
[0246] In one example, it can be determined, based on a predefined method, that the second beam corresponding to the second DCI is the same beam as the first beam corresponding to the first DCI.
[0247] The above is merely an illustrative example, and this disclosure does not limit the method of determining the transmission resources of the second DCI based on a predefined method.
[0248] In step S2105, network device 102 sends a second DCI to terminal 101.
[0249] In some embodiments, terminal 101 receives a second DCI.
[0250] In some embodiments, terminal 101 receives the second DCI on the transmission resources of the second DCI.
[0251] In some embodiments, for example Figure 4A As shown, when the second DCI and the first DCI are transmitted on the same time domain resources, the terminal 101 can detect and receive the second DCI on the same time unit as the first DCI, based on the frequency domain resources of the second DCI (which are determined based on the first DCI and the second configuration), within the search space corresponding to the second DCI indicated by the second configuration, and on the second beam corresponding to the second DCI.
[0252] In some embodiments, for example Figure 4B As shown, when the second DCI and the first DCI are transmitted on different time domain resources, the terminal 101 can determine the time domain resources occupied by the second DCI based on the time domain resource offset indicated by the second configuration and the time domain resources occupied by the first DCI. On the time domain resources, based on the frequency domain resources of the second DCI (the frequency domain resources of the second DCI are determined based on the first DCI and the second configuration), and on the second beam corresponding to the second DCI, the terminal can detect and receive the second DCI.
[0253] The above is merely an illustrative example, and this disclosure does not limit the method by which the terminal 101 detects and receives the second DCI.

Figure 3B As shown, this disclosure relates to an information transmission method, which can be executed by a network device 102. The method includes: Step S3201: Send the first DCI and the second configuration.
[0283] In some embodiments, the first DCI is associated with the second DCI.
[0284] In some embodiments, network device 102 sends a first DCI and a second configuration to terminal 101.
[0285] In some embodiments, terminal 101 receives a first DCI and a second configuration.
[0286] In some embodiments, optional implementations of step S3201 can be found in [reference needed]. Figure 2 Optional implementation methods of step S2101, and Figure 2 Other related parts in the embodiments involved will not be described in detail here.

[0291] In some embodiments, steps S3201 to S3202 are optional, and one or more of these steps may be omitted or substituted in different embodiments.
[0292] In some embodiments, the execution order of steps S3201 to S3202 is not limited.
[0293] In the above embodiments, the network device can send a first DCI and a second configuration to the terminal so that the terminal can determine the transmission information of the second DCI. Furthermore, by sending the second DCI to the terminal, the complexity and overhead of blind detection by the terminal are reduced, and the reliability of DCI transmission is improved.
[0294] The above process is further illustrated with examples below.
[0295] In this embodiment of the disclosure, the terminal receives a second configuration and a first DCI, and determines the transmission resources of the second DCI.
[0296] Terminal side: The terminal receives the second configuration and the first DCI, determines the transmission resource of the second DCI, and receives the second DCI on the transmission resource.
[0297] For example, a first configuration is introduced, which is associated with the first DCI.
[0298] For example, the second configuration is associated with the second DCI, and the second configuration is used to configure at least one of the following: The identifier of the second configuration; the identifier of the first configuration, which is associated with the first DCI; The identifier of the control resource set associated with the second configuration; the time-domain resource offset, which indicates the offset of the time-domain resource of the second DCI relative to the time-domain resource of the first DCI; The sub-time unit in which the Physical Downlink Control Channel (PDCCH) is located within a time unit; The number of sub-resources corresponding to AL; AL; DCI format.
[0299] For example, if the second configuration does not configure a time domain resource offset, or the time domain resource offset is 0, then the first DCI and the second DCI are transmitted on the same time unit.
[0300] Method 1: The terminal receives a second configuration and a first DCI, and determines the transmission resources for the second DCI, wherein the first DCI and the second DCI can be transmitted in the same time unit, for example... Figure 4A As shown.
[0301] The terminal determines the association between the second configuration and the first SS configuration based on a predefined method: For example, the second configuration and the first configuration correspond to the same identifier, and the terminal determines that the first configuration is associated with the second configuration.
[0302] For example, the second configuration and the first configuration correspond to the same time unit, and the terminal determines that the first configuration is associated with the second configuration.
[0303] The terminal determines the association between the second configuration and the first configuration based on the first signaling: For example, the first signaling is used for at least one of the following: configuring an identifier of a first configuration associated with the second configuration in the second configuration; configuring an identifier of a second configuration associated with the first configuration in the first configuration. For example, a terminal receives a first DCI, determines the PDCCH resource corresponding to the second DCI, and the first DCI is used to indicate at least one of the following: The AL corresponding to the PDCCH resource; The sub-resource index corresponding to the PDCCH resource, such as the PDCCH candidate index.
[0304] For example, the terminal determines the second beam corresponding to the second DCI based on a predefined method: For example, the second beam is the same beam as the first beam.
[0305] Method 2: The terminal receives the second configuration and the first DCI, and determines the transmission resources of the second DCI.
[0306] The terminal determines the first configuration associated with the second configuration based on the first signaling.
[0307] For example, the first signaling is used for at least one of the following: configuring an identifier of a first configuration associated with the second configuration in the second configuration; configuring an identifier of a second configuration associated with the first configuration in the first configuration. The terminal determines the time-domain resources of the second DCI based on the second configuration.
[0308] For example, the terminal determines the time-domain resource offset based on the second configuration, and offsets the time-domain resources of the first DCI to obtain the time-domain resources of the second DCI, for example... Figure 4B As shown.
[0309] For example, the terminal receives the first DCI and determines the PDCCH resource corresponding to the second DCI. The specific method is similar to that in Embodiment 1, and will not be repeated here.
[0310] For example, the terminal determines the second beam corresponding to the second DCI transmission based on a predefined method: The specific method is similar to that in Example 1, and will not be repeated here.
[0311] For example, the terminal determines the second beam based on the second signaling: For example, the second signaling can be the first DCI.
[0312] For example, a beam list is configured based on higher-level signaling, and a beam is indicated in the second signaling list.
[0313] Network device side: The network device sends a second configuration and a first DCI, indicates the transmission resources for the second DCI, and sends the second DCI on those transmission resources.
[0314] For example, a first configuration is introduced, which is associated with the first DCI.
[0315] For example, the second configuration is associated with a second DCI, and the second configuration is used to configure at least one of the following: The identifier of the second configuration; the identifier of the first configuration, which is associated with the first DCI; The identifier of the control resource set associated with the second configuration; the time-domain resource offset, which indicates the offset of the time-domain resource of the second DCI relative to the time-domain resource of the first DCI; The sub-time unit in which the Physical Downlink Control Channel (PDCCH) is located within a time unit; The number of sub-resources corresponding to AL; AL; DCI format.
[0316] Method 1: The network device sends a second configuration and a first DCI, indicating the transmission resources of the second DCI, wherein the first DCI and the second DCI can be transmitted in the same time unit.
[0317] Network devices can determine the association between the second configuration and the first configuration based on a predefined method: For example, the second configuration and the first configuration correspond to the same identifier so that the terminal can determine that the first configuration is associated with the second configuration.
[0318] For example, the second configuration and the first configuration correspond to the same time unit, and the terminal determines that the first configuration is associated with the second configuration.
[0319] The network device can send a first signaling message indicating the association between the second configuration and the first configuration: For example, the first signaling is used for at least one of the following: configuring an identifier of a first configuration associated with the second configuration in the second configuration; configuring an identifier of a second configuration associated with the first configuration in the first configuration.
[0320] For example, a network device sends a first DCI indicating the PDCCH resource corresponding to the second DCI, wherein the first DCI is used to indicate at least one of the following: The AL corresponding to the PDCCH resource; The sub-resource index corresponding to the PDCCH resource, such as the PDCCH candidate index.
[0321] For example, the network device transmits the second DCI and the first DCI based on the same beam.
[0322] Method 2: The network device sends a second configuration and a first DCI, indicating the transmission resources of the second DCI.
[0323] The network device sends a first signaling instruction indicating a first configuration associated with the second configuration.
[0324] For example, the first signaling is used for at least one of the following: configuring an identifier of a first configuration associated with the second configuration in the second configuration; configuring an identifier of a second configuration associated with the first configuration in the first configuration. The network device sends the second configuration and the first DCI, indicating the time-domain resources of the second DCI.
[0325] For example, the network device indicates a list of time-domain resource offsets based on a second configuration and a specific time-domain resource offset based on a first DCI.
[0326] For example, the base station sends a first DCI to indicate the PDCCH resource corresponding to the second DCI. The specific method is similar to that in Embodiment 1, and will not be repeated here.
[0327] For example, the base station transmits the second DCI and the first DCI based on the same beam.
[0328] For example, the base station sends a second signaling instruction to the second beam: For example, the second signaling can be the first DCI.
[0329] For example, a beam list is configured based on higher-level signaling, and a second signaling indicates a beam in that list.
[0330] In a specific implementation of the present invention, one possible implementation is that the terminal receives the first DCI and the second configuration, and determines the transmission resources of the second DCI.
[0331] The first DCI is, for example, the 1st stage DCI in a two-stage DCI. For example, the second DCI can be the 2nd stage DCI in a two-stage DCI, but the present invention is not limited thereto.
[0332] The first DCI and / or the second DCI can be the DCI corresponding to USS or the DCI corresponding to CSS, and the present invention does not limit this.
[0333] The second configuration corresponding to the second DCI can be based on an existing configuration design or a different design from the first configuration corresponding to the first DCI. The second configuration is mainly used by the terminal to determine the transmission resources of the second DCI, and the second configuration is used to configure at least one of the following: The identifier of the second configuration; the identifier of the first configuration, which is associated with the first DCI; The identifier of the control resource set associated with the second configuration; the time-domain resource offset, which indicates the offset of the time-domain resource of the second DCI relative to the time-domain resource of the first DCI; The sub-time unit in which the Physical Downlink Control Channel (PDCCH) is located within a time unit; The number of sub-resources corresponding to AL; AL; DCI format.
[0334] For example, if the second configuration does not configure a time domain resource offset, or the time domain resource offset is 0, then the first DCI and the second DCI are transmitted on the same time unit.
[0335] For example, a time unit may include one or more of the following: frame, subframe, time slot, sub-time slot, symbol.
[0336] Taking time units as time slots as an example, the second configuration can indicate the specific symbol position of the second DCI within its time slot, for example, it can be indicated based on the indicator signaling monitoringSymbolsWithinSlot.
[0337] For example, the DCI format of the second configuration indication can be the DCI format of the second DCI.
[0338] Based on the second configuration, the terminal determines that the received configuration is the second configuration based on at least one of the following methods: Method 1: The configuration is determined based on a predefined method, which is the second configuration.
[0339] For example, if an identifier in the configuration is used for a second configuration, then the configuration is determined to be the second configuration. For example, a specific set of identifiers is defined for the second configuration, and this set of identifiers can only be applied to the second configuration.
[0340] For example, if the configuration contains a DCI format corresponding to the second DCI, the terminal determines that the configuration is the second configuration.
[0341] Method 2: Determine the configuration as the second configuration based on the indication information.
[0342] For example, the type of the second configuration can be indicated by an indication message, such as introducing a specific field in the second configuration, which indicates that the configuration is the second configuration. If the indication message is not present in the configuration, then the configuration is determined to be the first configuration.
[0343] Example 1, corresponding to a specific implementation of the present invention, is a possible implementation in which the first DCI and the second DCI are transmitted on the same time-domain resources. The terminal determines the transmission resources corresponding to the second DCI based on at least one of the following methods.
[0344] Based on this, to enable the first DCI and the second DCI to be transmitted on the same time-domain resources, the first configuration and the second configuration correspond to the same MO, or the MO of the second configuration is a subset of the first configuration, or the MO of the first configuration is a subset of the second configuration. For example, the time units corresponding to the first configuration and the time units corresponding to the second configuration partially overlap.
[0345] Based on this, corresponding to the same MO, the first configuration and the second configuration can be associated with the same CORESET. Alternatively, the first configuration and the second configuration can be associated with different CORESETs, which are configured based on Frequency Division Multiplexing (FDM).
[0346] Relationship: The terminal can determine the first configuration associated with the second configuration based on a predefined method. For example, it can determine the first configuration associated with the second configuration based on a configuration identifier.
[0347] For example, if the first configuration and the second configuration correspond to the same identifier, the terminal determines that the two configurations are associated, and the corresponding first DCI and second DCI are associated. For example, the terminal can determine the transmission resources of the associated second DCI based on the first DCI.
[0348] Alternatively, the terminal determines the association between the first configuration and the second configuration based on the first signaling. For example, the first signaling is used for at least one of the following: configuring an identifier of the first configuration associated with the second configuration in the second configuration; configuring an identifier of the second configuration associated with the first configuration in the first configuration. For instance, if the first configuration and the second configuration are associated, the terminal determines that their corresponding first DCI and second DCI are associated. For instance, the terminal can determine the transmission resources of the associated second DCI based on the first DCI.
[0349] Time-domain resources: To ensure that the first DCI and the second DCI correspond to the same MO, one possible implementation is that the first configuration and the second configuration correspond to the same MO. Alternatively, the MO of the second configuration is a subset of the MO of the first configuration, or vice versa; this invention is not limited to this.
[0350] In the relevant mechanism, the MO defined based on the search space can be based on different granularity indicators, such as different MOs within a time slot (e.g., indicated by the indicator signaling monitoringSymbolsWithinSlot), different MOs between time slots (e.g., indicated by the indicator signaling duration), or different periodic transmission positions (e.g., indicated by the indicator signaling monitoringSlotPeriodicityAndOffset), as exemplarily described below. Figure 4C As shown.
[0351] One possible implementation is that the terminal determines the time-domain resources of the second DCI based on a predefined method. For example, based on the MO where the first DCI is located, the second DCI is transmitted based on the Nth time unit after the first DCI transmits the MO, where N can be determined based on a predefined method, for example, N=1.
[0352] The time unit can be defined based on one of the following indications: Time slot; for example, the MO corresponding to the same symbol position in the next time slot; MO; Periodicity; for example, the same MO position corresponding to the next period; symbol; frame; Subframe; Sub-hour slot.
[0353] One possible implementation is that the terminal determines the time-domain resources of the second DCI based on a predefined method. For example, based on the MO where the first DCI is located, the second DCI is transmitted in the Nth time unit after the first DCI transmits the MO, where N is determined based on signaling indications from the network device side, such as through the first DCI indication. The time unit is based on the above definition and will not be elaborated further here.
[0354] Frequency domain resources: The terminal can determine the PDCCH resource corresponding to the second DCI. In one possible implementation, the PDCCH resource corresponds to an AL. For example, the terminal configures the maximum number of corresponding sub-resources based on a specific AL, such as the maximum number of PDCCH candidates.
[0355] Furthermore, the terminal determines the specific PDCCH resource based on the first DCI, wherein the first DCI may indicate at least one of the following information: The AL corresponding to the PDCCH resource; Sub-resource indexes corresponding to PDCCH resources, such as the PDCCH candidate index.
[0356] In one possible implementation, the PDCCH resource corresponds to multiple ALs. For example, the terminal determines candidate PDCCH resources based on each AL and the maximum number of sub-resources corresponding to each AL, such as the maximum number of PDCCH candidates. Further, the terminal determines the specific PDCCH resource based on a first DCI, which may indicate at least one of the following information: Multiple ALs corresponding to PDCCH resources; Multiple sub-resource indexes corresponding to PDCCH resources, such as the PDCCH candidate index corresponding to each AL; The mapping relationship between the PDCCH resource and each sub-resource.
[0357] Transmission beam: One possible implementation is that the terminal determines the second beam corresponding to the second DCI based on a predefined method. For example, the second beam is determined based on the first beam corresponding to the first DCI, such as the second beam being the same beam as the first beam; or the second DCI is determined based on the beam where the terminal initiates random access.
[0358] In one possible implementation, the terminal determines the second beam based on the second signaling. For example, the terminal determines the second beam based on the first DCI.
[0359] For example, the terminal determines a beam list based on higher-layer signaling, such as RRC signaling, SI, or MAC CE signaling, and indicates a beam in the list based on a second signaling, such as MAC CE or DCI.
[0360] Example 2, corresponding to a specific implementation of the present invention, is a possible implementation in which the first configuration and the second configuration correspond to different identifiers, and the first DCI and the second DCI correspond to different time-domain resources. The terminal determines the transmission information corresponding to the second DCI based on at least one of the following methods.
[0361] Relationship: As described above, the terminal determines the association between the first configuration and the second configuration based on the first signaling. For example, the first signaling is used for at least one of the following: configuring an identifier of the first configuration associated with the second configuration in the second configuration; configuring an identifier of the second configuration associated with the first configuration in the first configuration. For example, if the first configuration and the second configuration are associated, the terminal determines that their corresponding first DCI and second DCI are associated. For example, the terminal can determine the transmission resources of the associated second DCI based on the first DCI.
[0362] Among them, the time domain resources occupied by the second DCI are, for example Figure 4B As shown.
[0363] One possible implementation is that the terminal determines the time-domain resources of the second DCI based on a predefined method. For example, based on the MO where the first DCI is located, the second DCI is transmitted based on the Nth time unit after the first DCI transmits the MO, where N is determined based on a predefined method, for example, N=1; wherein, the candidate MO of the second DCI is based on a second configuration, or it may not be based on a second configuration, and the present invention does not limit this.
[0364] The time unit can be defined based on one of the following indications: Time slot; for example, the MO corresponding to the same symbol position in the next time slot; MO; Periodicity; for example, the same MO position corresponding to the next period; symbol; frame; Subframe; Sub-hour slot.
[0365] In one possible implementation, the terminal determines the time-domain resources of the second DCI based on indication signaling. For example, the second DCI is transmitted in the Nth time unit after the first DCI transmits the MO, where N is indicated by indication signaling, for example, by the first DCI. The time unit is based on the above definition and will not be repeated here. The candidate MOs of the second DCI are based on a second configuration, but may not be based on a second configuration; this invention does not limit this.
[0366] One possible implementation is that the terminal determines the time-domain resources of the second DCI based on indication signaling. For example, it determines the time-domain resource offset of the second DCI transmission relative to the first DCI transmission through higher-layer signaling, or it determines a list of time-domain resource offsets of the second DCI transmission relative to the first DCI transmission based on higher-layer signaling and indicates one of the time-domain resource offsets based on the first DCI. The time unit is based on the above definition and will not be described again here.
[0367] For example, the terminal determines the time-domain resource offset based on the first DCI, the time-domain resource offset belongs to a time-domain resource offset list, and the time-domain resource offset list is determined based on the second configuration.
[0368] The terminal can obtain the symbol corresponding to the second DCI within the time slot based on indication signaling, for example, based on the second configuration, or based on the first DCI.
[0369] Frequency domain resources: Its indication method is similar to that of Embodiment 1, and will not be described again here.
[0370] Transmission beam: One possible implementation is that the terminal determines the second beam corresponding to the second DCI based on a predefined method. For example, the second beam is determined based on the first beam corresponding to the first DCI, such as the second beam being the same beam as the first beam; or the second DCI is determined based on the beam where the terminal initiates random access.
[0371] In one possible implementation, the terminal determines the second beam based on the second signaling. For example, the terminal determines the second beam based on the first DCI.
[0372] For example, the terminal determines a beam list based on higher-layer signaling, such as RRC signaling, SI, or MAC CE signaling, and indicates a beam in the list based on a second signaling, such as MAC CE or DCI.
[0373] For example, if the beam determined by the terminal based on the second signaling is different from the first beam, the terminal ignores the second signaling.
[0374] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.
[0375] 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), and 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), such as a field-programmable gate array (FPGA), which 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.
[0376] 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). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. 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. Furthermore, 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), or a Deep Learning Processing Unit (DPU).
