[0095] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0096] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0097] The embodiments of the present disclosure 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), future generation 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 (registered trademark), Public Land Mobile Network (PLMN) networks, systems utilizing other communication methods, and next-generation systems based on these. Furthermore, a combination of multiple systems (for example, a combination of LTE or LTE-A with 5G) may also be used.

[0098] The terminal can improve the communication quality between the terminal and the network equipment through carrier aggregation. To further improve the flexibility of terminal carrier usage, the terminal can configure the bandwidth part (BWP) used by the terminal through, for example, RRC reconfiguration messages, further improving the flexibility of carrier usage and improving spectrum utilization.

[0099] However, using RRC reconfiguration messages to configure carriers is not flexible enough. Therefore, to improve carrier configuration flexibility, a single MC-DCI can be used to schedule a terminal's data transmission across multiple cells. To support MC-DCI scheduling, network equipment must be aware of whether the terminal can match the corresponding carrier scheduling capabilities. The specific solution is as follows:

[0100] FIG2 is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to an information transmission method, which includes:

[0101] Step S2101 : Terminal 101 sends capability indication information to network device 102 .

[0102] In some embodiments, the network device 102 receives the capability indication information.

[0103] In some embodiments, the capability indication information may be used to indicate that the terminal supports multi-cell downlink control information (MC-DCI) scheduling. It is understandable that the terminal 101 has advanced terminal capabilities compared to traditional terminals.

[0104] In some embodiments, the capability indication information may also be used to indicate the capability of the terminal 101 to support processing of unicast DCI.

[0105] For example, the capabilities may include the number of DCIs processed, the type of processing (for example, the type of processing is unicast DCI, for example, the type of processing includes downlink DCI or uplink DCI, for example, the type of processing includes uplink unicast DCI and downlink unicast DCI), the maximum length of DCI, the DCI format type, etc.

[0106] In an example, the unicast DCI includes at least one of the following: MC-DCI, where MC-DCI is used to schedule at least one cell in the same cell set; and traditional DCI, where traditional DCI is used to schedule a single cell.

[0107] Exemplarily, MC-DCI is DCI used to schedule one or more cells in a cell set, where the cell set includes at least one cell. The cell set means that cells belonging to the cell set can be scheduled by the same MC-DCI.

[0108] The MC-DCI format types include but are not limited to at least one of the following: DCI format 0_3; DCI format 1_3.

[0109] Among them, DCI format 0_3 is an MC-DCI format used to schedule the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) of at least one cell in the cell set.

[0110] Among them, DCI format 1_3 is an MC-DCI format used to schedule the physical downlink shared channel (PDSCH) of at least one cell in the cell set.

[0111] Exemplarily, the legacy DCI may be DCI in Release 15, Release 16, or Release 17, and the legacy DCI is used to schedule a single cell.

[0112] The legacy DCI format includes but is not limited to a combination of one or more of the following: DCI format 0_0; DCI format 1_0; DCI format 0_1; DCI format 1_1; DCI format 0_2; DCI format 1_2.

[0113] Among them, DCI format 0_0, DCI format 0_1, and DCI format 0_2 are legacy DCI formats used to schedule the PUSCH of a single cell.

[0114] Among them, DCI format 1_0, DCI format 1_1, and DCI format 1_2 are legacy DCI formats used to schedule the PDSCH of a single cell.

[0115] In some embodiments, the ability of terminal 101 to support processing unicast DCI can meet at least one of the following: exceeding the minimum ability of a traditional terminal to support processing unicast DCI when accessing a network device; being equivalent to the minimum ability of a traditional terminal to support processing unicast DCI when accessing a network device; corresponding to different subcarrier spacing SCS combinations of the scheduling cell and the scheduled cell; corresponding to different full-duplex modes supported by the scheduling cell and / or the scheduled cell.

[0116] The legacy terminal may be a terminal supporting at least one of Release-15 (R-15), Release-16 (R-16), and Release-17 (R-17). The legacy terminal does not support MC-DCI scheduling.

[0117] In an example, the capability of terminal 101 to support processing of unicast DCI exceeds the minimum capability of a traditional terminal to support processing of unicast DCI when accessing a network device.

[0118] In an example, the capability of terminal 101 to support processing of unicast DCI is equivalent to the minimum capability of a traditional terminal to support processing of unicast DCI when accessing a network device.

[0119] The minimum capabilities required for traditional terminals to support unicast DCI processing when accessing network devices include:

[0120] In one time slot, one downlink DCI is processed. The downlink DCI is used to perform downlink data scheduling.

[0121] One time slot supports processing of one or two uplink DCIs, where uplink DCI is used to perform uplink data scheduling.

[0122] In one example, the capability of the terminal 101 to support processing of unicast DCI corresponds to different sub-carrier space (SCS) combinations of the scheduling cell and the scheduled cell.

[0123] Exemplarily, the SCS combination includes any of the following: the SCS of the scheduling cell is the same as the SCS of the scheduled cell; the SCS of the scheduling cell is smaller than the SCS of the scheduled cell; the SCS of the scheduling cell is larger than the SCS of the scheduled cell.

[0124] That is to say, the capability indication information reported by the terminal 101 can be used to indicate the energy supported for processing unicast DCI when corresponding to any SCS combination.

[0125] It is understandable that under different SCS combinations, the terminal 101 may have different capabilities for processing unicast DCI, and / or the terminal's capabilities are effective under one or several specified SCS combinations.

[0126] In an example, the capability of the terminal 101 to process unicast DCI may correspond to different full-duplex modes supported by the scheduling cell and / or the scheduled cell.

[0127] Exemplarily, the scheduling cell and / or the scheduled cell may support at least one full-duplex mode of time division duplexing (TDD) and frequency division duplexing (FDD).

[0128] That is, the capability indication information reported by the terminal 101 may be used to indicate the energy of the terminal for processing unicast DCI when the scheduling cell and / or the scheduled cell supports different full-duplex systems.

[0129] It is understandable that when the scheduling cell and / or the scheduled cell supports different full-duplex modes, the terminal 101 may have different capabilities for processing unicast DCI, and / or the terminal's capabilities take effect when the scheduling cell and / or the scheduled cell supports a specified full-duplex mode.

[0130] The scheduling cell is a cell in which the terminal 101 needs to monitor a corresponding search space (SS). It can be understood that the scheduling cell is a cell that performs one or more carrier scheduling for the terminal 101.

[0131] A scheduled cell is a cell in a cell set that can be scheduled by downlink control information sent by a scheduling cell.

[0132] In some embodiments, the capability indication information is used to indicate at least one of the following: a first maximum number; a size of a first time window; a second maximum number; a size of a second time window. In one example, the first maximum number is the maximum number of first-type unicast DCIs that the terminal 101 supports processing within the first time window.

[0133] The first type of unicast DCI is a unicast DCI used to perform downlink data scheduling, that is, the first type of unicast DCI is a downlink DCI.

[0134] The first time window is a continuous time domain range in which the terminal processes the first type of unicast DCI.

[0135] The first time window is associated with at least one of the SCS combination of the scheduling cell and the scheduled cell, and the full-duplex mode supported by the scheduling cell and / or the scheduled cell.

[0136] Exemplarily, if the terminal 101 exceeds the minimum capability of a traditional terminal supporting processing unicast DCI when accessing a network device, the first maximum number may be greater than 1.

[0137] Exemplarily, the terminal 101 has the same minimum capability as a traditional terminal in supporting processing unicast DCI when accessing a network device, and the first maximum number may be 1.

[0138] In an example, the first time window is a continuous time domain range in which the terminal processes the first type of unicast DCI.

[0139] The first type of unicast DCI is a unicast DCI used to perform downlink data scheduling, that is, the first type of unicast DCI is a downlink DCI.

[0140] The first time window is associated with at least one of the SCS combination of the scheduling cell and the scheduled cell, and the full-duplex mode supported by the scheduling cell and / or the scheduled cell.

[0141] In an example, the second maximum number is the maximum number of terminals that support processing of the second type of unicast DCI within the second time window.

[0142] The second type of unicast DCI is a unicast DCI used for performing uplink data scheduling, that is, the second type of unicast DCI is an uplink DCI.

[0143] The second time window is a continuous time domain range in which the terminal processes the second type of unicast DCI.

[0144] The second time window is associated with at least one of the SCS combination of the scheduling cell and the scheduled cell, and the full-duplex mode supported by the scheduling cell and / or the scheduled cell.

[0145] Exemplarily, if the terminal 101 exceeds the minimum capability of a traditional terminal to support processing unicast DCI when accessing a network device, the second maximum number may be greater than 2 (without distinguishing between the full-duplex mode supported by the scheduling cell and / or the scheduled cell).

[0146] If the scheduling cell and / or the scheduled cell supports frequency division duplexing, the second maximum number may be greater than 2.

[0147] If the scheduling cell and / or the scheduled cell supports time division duplexing, the second maximum number may be greater than 1.

[0148] Exemplarily, the terminal 101 has the same minimum capability as a traditional terminal in supporting processing unicast DCI when accessing a network device, and the first maximum number may be 2 (without distinguishing between the full-duplex mode supported by the scheduling cell and / or the scheduled cell).

[0149] If the scheduling cell and / or the scheduled cell supports frequency division duplexing, the second maximum number may be 2.

[0150] If the scheduling cell and / or the scheduled cell supports time division duplexing, the second maximum number may be 1.

[0151] In an example, the second time window is a continuous time domain range in which the terminal processes the second type of unicast DCI.

[0152] The second type of unicast DCI is a unicast DCI used for performing uplink data scheduling, that is, the second type of unicast DCI is an uplink DCI.

[0153] The second time window is associated with at least one of the SCS combination of the scheduling cell and the scheduled cell, and the full-duplex mode supported by the scheduling cell and / or the scheduled cell.

[0154] In one example, the capability indication information may also be used for at least one of the following: different SCS combinations of the scheduling cell and the scheduled cell; and full-duplex modes supported by the scheduling cell and / or the scheduled cell.

[0155] In one example, the capability indication information indicates the first maximum number of first-type unicast DCIs supported for processing by the terminal 101 within a first time window, and / or the second maximum number of second-type unicast DCIs supported for processing within a second time window, based on different SCS combinations and the full-duplex mode supported by the scheduling cell and / or the scheduled cell.

[0156] The above description is merely an exemplary description. The terminal may also indicate other carrier scheduling capabilities supported by the terminal through capability indication information, which is not limited in the present disclosure.

[0157] The following describes the content of the capability indication information reported by the terminal 101 for different types of unicast DCI, namely the first type of unicast DCI and the second type of unicast DCI mentioned above.

[0158] 1. For the first type of unicast DCI (downlink DCI)

[0160] The scheduling cell supports time division duplexing and / or frequency division duplexing, and / or the scheduled cell supports time division duplexing and / or frequency division duplexing.

[0161] When the scheduling cell supports time division duplex and / or frequency division duplex, and / or the scheduled cell supports time division duplex and / or frequency division duplex, the value of the first maximum number M remains unchanged. That is, when the scheduling cell supports time division duplex and / or frequency division duplex, and / or the scheduled cell supports time division duplex and / or frequency division duplex, the terminal 101's ability to process the first type of unicast DCI remains unchanged.

[0162] Exemplarily, the first maximum number M may be a positive integer greater than 1, for example, M may be 2, 3, 4, . . . .

[0163] Exemplarily, the first type of unicast DCI includes at least one of the following:

[0164] Downlink MC-DCI: Downlink MC-DCI is used to schedule downlink data of at least one cell in the same cell set. Exemplarily, the format of the downlink MC-DCI is DCI format1_3.

[0165] Legacy downlink DCI is legacy DCI used to schedule downlink data of a single cell. Exemplarily, the format of the legacy downlink DCI includes a combination of one or more of the following: DCI format1_0; DCI format1_1; DCI format1_2.

[0166] Among them, when the terminal 101 supports DCI format1_2, the terminal 101 can report it to the network device 102.

[0167] In one example, a first maximum number M of first-type unicast DCIs is used to schedule at least one cell within the cell set.

[0168] In an example, the size of the first time window is any one of the following: a time unit of the scheduling cell; or multiple consecutive time symbols within a time unit of the scheduling cell.

[0169] Exemplarily, the time unit may be in the form of a time slot, that is, the size of the first time window is a time slot of the scheduling cell.

[0170] Exemplarily, the time symbol refers to an Orthogonal Frequency Division Multiplexing symbol (OFDM symbol).

[0171] A time unit, such as a plurality of consecutive OFDM symbols within a time slot, constitutes a span.

[0172] Exemplarily, the size of the first time window is a plurality of consecutive OFDM symbols in a time slot of the scheduling cell, that is, a span of the scheduling cell.

[0175] In one example, the SCS of the scheduling cell is not equal to the SCS of the scheduled cell.

[0176] Exemplarily, the SCS of the scheduling cell is smaller than the SCS of the scheduled cell.

[0177] The scheduling cell supports time division duplexing and / or frequency division duplexing, and / or the scheduled cell supports time division duplexing and / or frequency division duplexing.

[0178] When the scheduling cell supports time division duplex and / or frequency division duplex, and / or the scheduled cell supports time division duplex and / or frequency division duplex, the value of the first maximum number M remains unchanged. That is, when the scheduling cell supports time division duplex and / or frequency division duplex, and / or the scheduled cell supports time division duplex and / or frequency division duplex, the terminal 101's ability to process the first type of unicast DCI remains unchanged.

[0179] Exemplarily, the first maximum number M may be a positive integer greater than 1, for example, M may be 2, 4, 8, . . .

[0180] Exemplarily, the first type of unicast DCI includes at least one of the following:

[0181] Downlink MC-DCI: Downlink MC-DCI is used to schedule downlink data of at least one cell in the same cell set. Exemplarily, the format of the downlink MC-DCI is DCI format1_3.

[0182] Legacy downlink DCI is used to schedule downlink data for a single cell. For example, the format of the legacy downlink DCI includes one or more of the following:

[0183] DCI format1_0; DCI format1_1; DCI format1_2.

[0184] Among them, when the terminal 101 supports DCI format1_2, the terminal 101 can report it to the network device 102.

[0185] In one example, a first maximum number M of first-type unicast DCIs is used to schedule at least one cell within the cell set.

[0186] At this time, the size of the first time window is any one of the following: a time unit of the scheduling cell; a plurality of consecutive time symbols within a time unit of the scheduling cell.

[0187] Exemplarily, the time unit may be in the form of a time slot, that is, the size of the first time window is a time slot of the scheduling cell.

[0188] Exemplarily, the time symbol refers to an OFDM symbol.

[0189] A time unit, such as multiple consecutive OFDM symbols within a time slot, constitutes a span.

[0190] Exemplarily, the size of the first time window is a plurality of consecutive OFDM symbols in a time slot of the scheduling cell, that is, a span of the scheduling cell.

[0191] In this embodiment, the capability indication information is used to indicate at least one of the following: a first maximum number M, where M is greater than 1; a size of a first time window, where the size of the first time window is a time slot of a scheduling cell or multiple consecutive OFDM symbols in a time slot.

[0192] That is, the terminal 101 informs the network device 102 through the capability indication information that the terminal 101 supports processing a first maximum number M of first-type unicast DCIs in a time slot of the scheduling cell or multiple consecutive OFDM symbols within a time slot.

[0193] In one example, the SCS of the scheduling cell is not equal to the SCS of the scheduled cell.

[0194] Exemplarily, the SCS of the scheduling cell is greater than the SCS of the scheduled cell.

[0195] The scheduling cell supports time division duplexing and / or frequency division duplexing, and / or the scheduled cell supports time division duplexing and / or frequency division duplexing.

[0196] When the scheduling cell supports time division duplex and / or frequency division duplex, and / or the scheduled cell supports time division duplex and / or frequency division duplex, the value of the first maximum number M remains unchanged. That is, when the scheduling cell supports time division duplex and / or frequency division duplex, and / or the scheduled cell supports time division duplex and / or frequency division duplex, the terminal 101's ability to process the first type of unicast DCI remains unchanged.

[0197] Exemplarily, the first maximum number M may be a positive integer greater than 1, for example, M may be 2, 4, 8, . . .

[0198] Exemplarily, the first type of unicast DCI includes at least one of the following: downlink MC-DCI, which is used to schedule downlink data for at least one cell within the same cell set. Exemplarily, the format of the downlink MC-DCI is DCI format1_3; and legacy downlink DCI, which is legacy DCI used to schedule downlink data for a single cell. Exemplarily, the format of the legacy downlink DCI includes a combination of one or more of the following: DCI format1_0; DCI format1_1; or DCI format1_2.

[0199] Among them, when the terminal 101 supports DCI format1_2, the terminal 101 can report it to the network device 102.

[0200] In one example, a first maximum number M of first-type unicast DCIs is used to schedule at least one cell within the cell set.

[0201] At this time, the size of the first time window is: multiple consecutive time units of the scheduling cell.

[0202] Exemplarily, the time unit may be in the form of a time slot, that is, the size of the first time window is a plurality of consecutive time slots of the scheduling cell.

[0203] In this embodiment, the capability indication information is used to indicate at least one of the following: a first maximum number M, where M is greater than 1; and a size of a first time window, where the size of the first time window is a plurality of consecutive time slots of the scheduling cell.

[0204] That is, the terminal 101 informs the network device 102 through the capability indication information that the terminal 101 supports processing a first maximum number M of first-type unicast DCIs in a plurality of consecutive time slots of the scheduling cell.

[0205] For example, when the SCS of the scheduling cell is twice the SCS of the scheduled cell, for example, the SCS of the scheduling cell is 30 kilohertz (kHz) and the SCS of the scheduled cell is 15 kHz, or the SCS of the scheduling cell is 60 kHz and the SCS of the scheduled cell is 30 kHz, etc., the number N of the multiple consecutive time slots may be 2. That is, the terminal 101 reports the first maximum number M of first-type unicast DCIs that it supports processing in every two consecutive time slots.

[0206] For example, when the SCS of the scheduling cell is four times the SCS of the scheduled cell, for example, the SCS of the scheduling cell is 60 kHz and the SCS of the scheduled cell is 15 kHz, or the SCS of the scheduling cell is 120 kHz and the SCS of the scheduled cell is 30 kHz, etc., the number N of the multiple consecutive time slots may be 4. That is, the terminal 101 reports the first maximum number M of first-type unicast DCIs that it supports processing in every 4 consecutive time slots.

[0207] For example, when the SCS of the scheduling cell is eight times the SCS of the scheduled cell, for example, when the SCS of the scheduling cell is 120 kHz and the SCS of the scheduled cell is 15 kHz, the number N of the multiple consecutive time slots may be 8. That is, the terminal 101 reports the first maximum number M of first-type unicast DCIs that it supports processing in every 8 consecutive time slots.

[0208] 2. Regarding the second type of unicast DCI (uplink DCI)

[0209] In one example, the SCS of the scheduling cell and the SCS of the scheduled cell are equal.

[0212] Exemplarily, the second type of unicast DCI includes at least one of the following: uplink MC-DCI, where the uplink MC-DCI is used to schedule uplink data of at least one cell in the same cell set. Exemplarily, the format of the uplink MC-DCI is DCI format 0_3; and legacy uplink DCI, where the format of the legacy DCI is used to schedule downlink data of a single cell. Exemplarily, the format of the legacy downlink DCI includes a combination of one or more of the following:

[0213] DCI format10_0; DCI format0_1; DCI format 0_2.

[0214] In which case, when the terminal 101 supports DCI format 0_2, the terminal 101 can report it to the network device 102.

[0215] In an example, the second maximum number M1 or M2 of second-type unicast DCIs is used to schedule at least one cell in the cell set.

[0216] In an example, the size of the second time window is any one of the following: a time unit of the scheduling cell; or multiple consecutive time symbols within a time unit of the scheduling cell.

[0222] That is to say, when the SCS of the scheduling cell is equal to the SCS of the scheduled cell, and the scheduling cell and / or the scheduled cell supports frequency division duplex, the terminal 101 informs the network device 102 through capability indication information that the terminal 101 supports processing the second maximum number M1 of the second type of unicast DCI in a time slot of the scheduling cell or multiple consecutive OFDM symbols within a time slot.

[0223] Exemplarily, M1 second-type unicast DCIs are used to schedule at least one cell in the cell set.

[0226] Exemplarily, M2 second-type unicast DCIs are used to schedule at least one cell in the cell set.

[0227] In one example, the SCS of the scheduling cell is not equal to the SCS of the scheduled cell.

[0228] Exemplarily, the SCS of the scheduling cell is smaller than the SCS of the scheduled cell.

[0229] When the scheduling cell and / or the scheduled cell supports frequency division duplex, the second maximum number M1 may be a positive integer greater than 1, for example, M1 may be 2, 4, 8, . . . .

[0230] When the scheduling cell and / or the scheduled cell supports time division duplexing, the second maximum number M2 may be a positive integer greater than 2, for example, M2 may be 4, 8, etc.

[0234] DCI format10_0; DCI format0_1; DCI format 0_2.

[0235] In which case, when the terminal 101 supports DCI format 0_2, the terminal 101 can report it to the network device 102.

[0239] Exemplarily, the time symbol refers to an OFDM symbol.

[0240] A time unit, such as multiple consecutive OFDM symbols within a time slot, constitutes a span.

[0241] Exemplarily, the size of the first time window is a plurality of consecutive OFDM symbols in a time slot of the scheduling cell, that is, a span of the scheduling cell.

[0242] In this embodiment, when the scheduling cell and / or the scheduled cell supports frequency division duplex, the capability indication information is used to indicate at least one of the following: a second maximum number M1, M1 is greater than 1; the size of the second time window, the size of the second time window is a time slot of the scheduling cell or multiple consecutive OFDM symbols in a time slot.

[0243] That is to say, when the SCS of the scheduling cell is equal to the SCS of the scheduled cell, and the scheduling cell and / or the scheduled cell supports frequency division duplex, the terminal 101 informs the network device 102 through capability indication information that the terminal 101 supports processing the second maximum number M1 of the second type of unicast DCI in a time slot of the scheduling cell or multiple consecutive OFDM symbols within a time slot.

[0244] Exemplarily, M1 second-type unicast DCIs are used to schedule at least one cell in the cell set.

[0245] In this embodiment, when the scheduling cell and / or the scheduled cell supports time division duplexing, the capability indication information is used to indicate at least one of the following: a second maximum number M2, M2 being greater than 2;

[0246] The size of the second time window is a time slot of the scheduling cell or a plurality of consecutive OFDM symbols in a time slot.

[0247] That is to say, when the SCS of the scheduling cell is equal to the SCS of the scheduled cell, and the scheduling cell and / or the scheduled cell supports frequency division duplex, the terminal 101 informs the network device 102 through capability indication information that the terminal 101 supports processing the second maximum number M2 of the second type of unicast DCI in a time slot of the scheduling cell or multiple consecutive OFDM symbols within a time slot.

[0248] Exemplarily, M2 second-type unicast DCIs are used to schedule at least one cell in the cell set.

[0249] In one example, the SCS of the scheduling cell is not equal to the SCS of the scheduled cell.

[0250] Exemplarily, the SCS of the scheduling cell is greater than the SCS of the scheduled cell.

[0251] When the scheduling cell and / or the scheduled cell supports frequency division duplex, the second maximum number M1 may be a positive integer greater than 1, for example, M1 may be 2, 4, 8, . . . .

[0252] When the scheduling cell and / or the scheduled cell supports time division duplexing, the second maximum number M2 may be a positive integer greater than 2, for example, M2 may be 4, 8, etc.

[0253] Exemplarily, the second type of unicast DCI includes at least one of the following: uplink MC-DCI, where the uplink MC-DCI is used to schedule uplink data of at least one cell in the same cell set. Exemplarily, the format of the uplink MC-DCI is DCI format 0_3; traditional uplink DCI, which is legacy DCI used to schedule downlink data of a single cell.

[0254] Exemplarily, the format of the conventional downlink DCI includes a combination of one or more of the following: DCI format 0_0; DCI format 0_1; and DCI format 0_2.

[0255] In which case, when the terminal 101 supports DCI format 0_2, the terminal 101 can report it to the network device 102.

[0256] In an example, the second maximum number M1 or M2 of second-type unicast DCIs is used to schedule at least one cell in the cell set.

[0257] In an example, the size of the second time window is a plurality of consecutive time units of the scheduling cell.

[0258] Exemplarily, the time unit may be in the form of a time slot, that is, the size of the first time window is a plurality of consecutive time slots of the scheduling cell.

[0259] In this embodiment, when the scheduling cell and / or the scheduled cell supports frequency division duplex, the capability indication information is used to indicate at least one of the following: a second maximum number M1, M1 is greater than 1; the size of the second time window, the size of the second time window is multiple consecutive time slots of the scheduling cell.

[0260] That is, the terminal 101 informs the network device 102 through the capability indication information that the terminal 101 supports processing the second maximum number M1 of the second type of unicast DCIs in multiple consecutive time slots of the scheduling cell.

[0261] For example, when the SCS of the scheduling cell is twice the SCS of the scheduled cell, for example, the SCS of the scheduling cell is 30 kilohertz (kHz) and the SCS of the scheduled cell is 15 kHz, or the SCS of the scheduling cell is 60 kHz and the SCS of the scheduled cell is 30 kHz, etc., the number N of the multiple consecutive time slots may be 2. That is, the terminal 101 reports the second maximum number M1 of second-type unicast DCIs that it supports processing in every two consecutive time slots.

[0262] For example, when the SCS of the scheduling cell is four times the SCS of the scheduled cell, for example, the SCS of the scheduling cell is 60 kilohertz (kHz) and the SCS of the scheduled cell is 15 kHz, or the SCS of the scheduling cell is 120 kHz and the SCS of the scheduled cell is 30 kHz, etc., the number N of the multiple consecutive time slots may be 4. That is, the terminal 101 reports the second maximum number M1 of second-type unicast DCIs that it supports processing in every 4 consecutive time slots.

[0263] For example, when the SCS of the scheduling cell is eight times the SCS of the scheduled cell, for example, when the SCS of the scheduling cell is 120 kilohertz (kHz) and the SCS of the scheduled cell is 15 kHz, the number N of the multiple consecutive time slots may be 8. That is, the terminal 101 reports the second maximum number M1 of second-type unicast DCIs that it supports processing in every 8 consecutive time slots.

[0264] Exemplarily, M1 second-type unicast DCIs are used to schedule at least one cell in the cell set.

[0265] In this embodiment, when the scheduling cell and / or the scheduled cell supports time division duplexing, the capability indication information is used to indicate at least one of the following: a second maximum number M2, M2 is greater than 2; the size of the second time window, the size of the second time window is multiple consecutive time slots of the scheduling cell.

[0266] For example, when the SCS of the scheduling cell is twice the SCS of the scheduled cell, for example, the SCS of the scheduling cell is 30 kilohertz (kHz) and the SCS of the scheduled cell is 15 kHz, or the SCS of the scheduling cell is 60 kHz and the SCS of the scheduled cell is 30 kHz, etc., the number N of the multiple consecutive time slots may be 2. That is, the terminal 101 reports the second maximum number M2 of second-type unicast DCIs that it supports processing in every two consecutive time slots.

[0267] For example, when the SCS of the scheduling cell is four times the SCS of the scheduled cell, for example, the SCS of the scheduling cell is 60 kilohertz (kHz) and the SCS of the scheduled cell is 15 kHz, or the SCS of the scheduling cell is 120 kHz and the SCS of the scheduled cell is 30 kHz, etc., the number N of the multiple consecutive time slots may be 4. That is, the terminal 101 reports the second maximum number M2 of second-type unicast DCIs that it supports processing in every 4 consecutive time slots.

[0268] For example, when the SCS of the scheduling cell is eight times the SCS of the scheduled cell, for example, when the SCS of the scheduling cell is 120 kilohertz (kHz) and the SCS of the scheduled cell is 15 kHz, the number N of the multiple consecutive time slots may be 8. That is, the terminal 101 reports the second maximum number M2 of second-type unicast DCIs that it supports processing in every 8 consecutive time slots.

[0269] Exemplarily, M2 second-type unicast DCIs are used to schedule at least one cell in the cell set.

[0309] Step S3201: Acquire capability indication information.

[0315] Step S3202: configure the search space.

For example, step S3201 may be implemented as an independent embodiment, step S3202 may be implemented as an independent embodiment, and steps S3201+S3202 may be implemented as independent embodiments, but are not limited thereto.

[0319] In some embodiments, step S3201 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if the network device 102 determines the terminal capability based on a predefined method or protocol agreement, step S3201 may not be performed.

[0320] In some embodiments, step S3202 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when network device 102 determines that terminal 101 does not support MC-DCI, it may determine the search space that terminal 101 needs to monitor according to an existing protocol agreement, and step S3202 may not be performed.

[0322] In the above embodiment, the network device can configure the search space that the terminal needs to monitor in the scheduling cell based on the capability indication information reported by the terminal, thereby reducing the complexity of controlling the terminal and improving the availability of multi-carrier scheduling DCI.

[0323] The above process is further illustrated by the following examples:

[0324] For a terminal, the number of DCIs it can process within a specific time unit is limited, reflecting the terminal's processing capability. In previous versions of the protocol, version 15, version 16, and version 17, the protocol defined the number of unicast DCIs that a terminal can process within a specific time unit.

[0325] Unicast DCI is defined as DCI sent by network devices to schedule specific terminal data or indicate specific terminal behavior. It is generally scrambled using different Radio Network Temporary Identifiers (RNTIs), such as the Cell-Radio Network Temporary Identifier (C-RNTI), Modular Coding Scheme Cell RNTI (MCS-C-RNTI), or Configured Scheduling RNTI (CS-RNTI). DCI is transmitted in the Common Search Space (CSS) or USS.

[0326] MC-DCI can only be transmitted within the USS and is scrambled using the C-RNTI or MCS-C-RNTI. MC-DCI can be unicast DCI.

[0327] However, if MC-DCI is considered as MC DCI and included in the terminal's DCI processing capability, the terminal's capability to process traditional unicast DCI will be limited.

[0328] In the embodiment of the present disclosure, the terminal reports the capability of processing the maximum number of unicast DCIs within a specific time unit.

[0329] Terminal side: A terminal with MC capability reports to the network its ability to support the maximum number of unicast DCIs that can be processed within a specific time unit:

[0330] The definition of high-level terminal capabilities meets the following principles

[0331] The maximum number of unicast DCIs that a high-order terminal can process within a specific time unit is no less than the capabilities defined in Rel-15, Rel-16, and Rel-17.

[0332] The high-order terminal capability reflects the different SCS combinations between the scheduling cell and the scheduled cell. In other words, the terminal's ability to process the maximum number of unicast DCIs within a specific time unit under different SCS combinations is different.

[0333] High-end terminal capabilities reflect the differences between terminals under different full-duplex modes, that is, terminals have different processing capabilities in TDD and FDD scenarios.

[0334] According to the above rules, the terminal reports the capability indication information to indicate at least one of the following:

[0335] 1. The terminal's ability to process the maximum number of unicast DL DCI (first type unicast DCI) packets. The terminal's ability to process the maximum number of unicast DCI packets includes at least one of the following:

[0354] Among them, the capabilities are the same for FDD and TDD

[0355] Among them, M unicast DCIs are used to schedule cells in the cell set.

[0356] 2. The terminal's ability to process the maximum number of unicast UL DCIs. The terminal's ability to process the maximum number of unicast DCIs includes at least one of the following:

[0374] 2.2.2.2 If the scheduling cell is TDD, the terminal supports processing M2 unicast DCIs within N consecutive slots of a scheduling cell.

[0375] Wherein, M1 is an integer greater than 1, typically M1=2; M2 is an integer greater than 2, typically M2=4.

[0376] Among them, unicast DCI includes DCI format 0_3 for scheduling a group of cells and DCI format 0_0, DCI format 0_1, and DCI format 0_2 for scheduling a single cell.

[0377] Among them, DCI format 0_2 needs to be reported only when the terminal supports monitoring DCI format

[0378] For different SCS combinations, for example, (30, 15), (60, 30), (120, 60), N = 2.

[0379] For example, the SCS combinations are (60, 15), (120, 30), and N=4.

[0380] For another example, corresponding to the SCS combination (120, 15), N=8.

[0381] M1 and M2 unicast DCIs are used to schedule cells within the cell set.

[0382] The network device can receive the maximum number of unicast DCIs supported for processing within a specific time range of the scheduling cell reported by the terminal, and determine the search space configuration on the scheduling cell based on the relevant terminal capabilities to ensure that the search space configuration on the scheduling cell does not exceed the terminal capabilities.

[0383] In Example 1, it is assumed that the terminal is a Rel-18 or later terminal and supports MC-DCI scheduling, that is, it supports scheduling data transmission on multiple cells through a single DCI. In this embodiment, the terminal is called an MC UE. MC UE supports the following features:

[0384] A maximum of 4 cell sets are supported in one PUCCH group;

[0385] In a cell set, up to 4 cells can be scheduled through one DCI.

[0386] In this embodiment, there is no restriction on the number of cell sets supported by the terminal and the maximum number of cells scheduled by one DCI. In this embodiment, it is assumed that the capability reflects the terminal's ability to process different DCIs within a specific time range of the scheduling cell.

[0387] In this embodiment, the MC UE reports to the network its ability to process unicast DCI within a specific time range on the scheduling cell. This capability satisfies the following requirements: 1) the maximum number of unicast DCIs that can be processed within a specific time unit is no less than the capability defined in Rel-15 / Rel-16 / Rel-17; 2) it reflects the different SCS combinations between the scheduling cell and the scheduled cell, i.e., the terminal's ability to process the maximum number of unicast DCIs within a specific time unit varies under different SCS combinations; and 3) it reflects the differences between the terminal in different full-duplex modes, i.e., the terminal has different processing capabilities in TDD and FDD scenarios.
