[0145] 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.

[0146] 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.

[0147] 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.

[0148] In a multi-cell scheduling system, a single DCI can schedule multiple cells. Therefore, the DCI needs to carry information about the multiple carriers, with one cell corresponding to one carrier. Network equipment can schedule data channels on one or more cells within a cell set based on the single DCI.

[0149] A cell set can contain Release-15 (Rel-15) component carriers (CCs) and Release-16 (Rel-16) CCs. Rel-15 CCs and Rel-16 CCs represent two types of downlink control channel monitoring capabilities, as follows:

[0150] On Rel-15 CCs, the terminal supports slot-level PDCCH monitoring capabilities.

[0151] On the Rel-16 CC, the terminal supports a span-level PDCCH monitoring capability.

[0152] The terminal may report its own PDCCH monitoring capability to the network device, and the network device configures an appropriate search space (SS) for the terminal according to the PDCCH monitoring capability reported by the terminal.

[0153] Rel-15 CC is a CC that does not support span-based UE capability definition. That is, on a Rel-15 CC, the PDCCH monitoring capability of the terminal is defined within the slot.

[0154] Rel-16 CC is a CC that supports span-based UE capability definition. That is, on a Rel-16 CC, the PDCCH monitoring capability of the terminal is defined within the span.

[0155] Specifically, the terminal can report the following three terminal capabilities:

[0156] Pure Rel-15 CC;

[0157] Pure Rel-16 CC;

[0158] Rel-15 CC+Rel-16 CC.

[0159] However, since the capability reporting and configuration of Rel-16 CC and Rel-15 CC are isolated, it will lead to ambiguity in the PDCCH monitoring capability supported by the terminal during multi-cell scheduling.

[0160] The terminal may report the capabilities related to the scheduling cell and the scheduled cell type based on whether the scheduling cell and the scheduled cell have the same sub-carrier space (SCS), as follows:

[0161] If the SCS and / or carrier type between the scheduling cell and the co-scheduled cell are the same, the reporting granularity can be any one of the following: {FR1 licensed FDD, FR1 licensed TDD, FR1 unlicensed TDD, FR2-1, FR2-2}.

[0162] If the SCS and / or carrier type are different between the scheduling cell and the co-scheduled cell, the reporting granularity is selected from the following for the scheduling cell and the co-scheduled cell respectively: {FR1 licensed FDD, FR1 licensed TDD, FR1 unlicensed TDD, FR2-1, FR2-2}.

[0163] Although terminal capabilities define the reporting of scheduling and co-scheduling cell types, even specific carrier types can still include Rel-15 CCs and Rel-16 CCs. This is because the capability definition does not reflect more granular capability values. In addition, if the capability definition and rules are followed, when all co-scheduled cells are Rel-16 CCs, additional scheduling restrictions will be imposed on network equipment because the terminal's PDCCH monitoring capability cannot be configured based on duration.

[0164] To address the issue of ambiguity regarding the PDCCH monitoring capabilities supported by a terminal during multi-cell scheduling, the present disclosure provides the following information transmission method, apparatus, and storage medium. This ensures that network equipment and the terminal have a consistent understanding of the PDCCH monitoring capabilities supported by the terminal across a set of cells, improving the reliability of the configured search space and, consequently, the reliability and availability of multi-cell scheduling.

[0165] FIG2A is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to an information transmission method, which includes:

[0166] In step S2101 , the network device 102 sends configuration information to the terminal 101 .

[0167] In some embodiments, terminal 101 receives the configuration information.

[0168] In some embodiments, the configuration information is used to configure a search space that the terminal 101 monitors on the scheduling cell, where the search space is used to transmit a physical downlink control channel (PDCCH).

[0169] In one example, a scheduling cell is a cell in which terminal 101 needs to monitor a corresponding search space (SS). The network device of the scheduling cell can select at least one cell from the cell set for multi-cell scheduling. It is understandable that terminal 101 receives DCI sent by network device 102 on the scheduling cell, and the DCI can schedule one or more cells in the cell set.

[0170] In an example, the search space is configured by the network device 102 for the terminal 101 based on the PDCCH monitoring capability supported by the terminal 101 in the cell set.

[0171] In the embodiment of the present disclosure, the network device 102 may determine the PDCCH monitoring capability supported by the terminal 101 in the cell set based on the terminal capability information reported by the terminal 101 , thereby configuring a search space for the terminal 101 .

[0172] Alternatively, the network device 102 may determine the PDCCH monitoring capability supported by the terminal 101 in the cell set based on a predefined manner, thereby configuring a search space for the terminal 101 .

[0173] Alternatively, the network device 102 may determine the PDCCH monitoring capability supported by the terminal 101 in the cell set based on other methods, thereby configuring a search space for the terminal 101. This disclosure is not limited to this.

[0174] In one example, the cell set may be understood as a set of scheduled cells.

[0175] In an example, the scheduled cells refer to cells scheduled by the same DCI.

[0176] Exemplarily, one or more cells in the cell set support being scheduled by the same DCI.

[0177] In an example, the scheduling cell may also belong to a cell set.

[0178] Exemplarily, the cell set includes scheduling cells and scheduled cells.

[0179] In an example, the scheduling cell does not belong to the cell set. Accordingly, the cell set only includes the scheduled cell.

[0180] It should also be noted that when the network device 102 configures the SS, it should ensure that the number of blind detections (BD) of the PDCCH by the terminal 101 in each duration or each time slot is less than or equal to the first number, and / or, the number of control channel elements (CCE) counted by the terminal 101 in each duration or each time slot is less than or equal to the first number, and / or, the ability of the terminal 101 to process unicast DCI in each duration or each time slot does not exceed the maximum capability of this type of terminal in unicast DCI.

[0181] Among them, the first digit, the first number, and the maximum capacity can be agreed upon by the protocol or determined in a predefined manner, and this disclosure does not limit this.

[0182] In some embodiments, terminal 101 may receive configuration information to determine a search space configured by network device 102 for terminal 101 on a scheduling cell, and terminal 101 monitors the search space to receive a PDCCH sent by network device 102 .

[0183] In some embodiments, the terminal 101 receives DCI carried on the PDCCH, and the DCI may be used to schedule at least one scheduled cell, that is, may be used to schedule at least one cell in the cell set.

[0184] In some embodiments, when the scheduling cell supports at least two types of component carriers, the PDCCH monitoring capability supported by the terminal in the cell set may be defined based on a duration or a time slot.

[0185] In one example, the at least two types of component carriers include:

[0186] A first type of component carrier, wherein the first type of component carrier supports defining the PDCCH monitoring capability of the terminal based on a span; and

[0187] The second type of component carrier supports the PDCCH monitoring capability of the terminal defined based on time slots.

[0188] Exemplarily, the first type of component carrier may be a Rel-16 CC.

[0189] Exemplarily, the first-category component carrier supports defining the PDCCH monitoring capability of the terminal based on a duration (span), including at least one of the following:

[0190] The terminal 101 counts the number of blind detections (BD) of the PDCCH within a span;

[0191] The terminal 101 counts the number of control channel elements (CCEs) within a span;

[0192] The capability of the terminal 101 to process unicast DCI (unicast DCI) within a span does not exceed the maximum capability of this type of terminal to process unicast DCI as agreed in the protocol.

[0193] Exemplarily, a span includes one or more consecutive Orthogonal Frequency Division Multiplexing symbols (OFDM symbols) belonging to the same time slot.

[0194] Exemplarily, the second type of component carrier may be a Rel-15 CC.

[0195] Exemplarily, the second-type component carrier supports defining the PDCCH monitoring capability of the terminal based on a slot, including at least one of the following:

[0196] The terminal 101 counts the number of BDs of the PDCCH in a slot;

[0197] Terminal 101 counts the number of CCEs in a slot;

[0198] The capability of the terminal 101 to process unicast DCI in one slot does not exceed the maximum capability of this type of terminal to process unicast DCI as agreed in the protocol.

[0199] In an example, when the scheduling cell supports both the first type component carrier and the second type component carrier, the PDCCH monitoring capability supported by the terminal in the cell set may be defined based on the duration.

[0200] In an example, when the scheduling cell supports both the first type component carrier and the second type component carrier, the PDCCH monitoring capability supported by the terminal in the cell set may be defined based on time slots.

[0201] In the above embodiment, the network device can configure a search space for the terminal, and the search space is configured by the network device for the terminal based on the PDCCH monitoring capability supported by the terminal in the cell set, thereby improving the reliability and availability of multi-cell scheduling.

[0202] FIG2B is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2B , the present disclosure embodiment relates to an information transmission method, which includes:

[0203] Step S2201 : Terminal 101 sends terminal capability information to network device 102 .

[0204] In some embodiments, the network device 102 receives the terminal capability information.

[0205] In some embodiments, the name of the terminal capability information is not limited.

[0206] In some embodiments, the terminal capability information is used to indicate the physical downlink control channel (PDCCH) monitoring capability supported by the terminal when the cell set includes at least two types of CCs.

[0207] In one example, the cell set may be a set of scheduled cells.

[0208] Exemplarily, one or more cells in the cell set support being scheduled by the same DCI.

[0209] When the network device 102 performs multi-cell scheduling, it may select one or more cells in the cell set and send scheduling information of the selected cells to the terminal 101 via the same DCI.

[0210] Exemplarily, the cell set may further include a scheduling cell, that is, one cell in the cell set may serve as the scheduling cell, and the other cells in the cell set may serve as the scheduled cells.

[0211] Exemplarily, the scheduling cell does not belong to the cell set, that is, the cell set only includes the scheduled cells, and the scheduling cell may select one or more cells from the cell set for multi-cell scheduling.

[0212] Exemplarily, a scheduling cell is a cell in which the terminal 101 needs to monitor a corresponding search space (SS), and the network device of the scheduling cell can select at least one cell from the cell set for the multi-cell scheduling. It is understandable that the terminal 101 receives the DCI sent by the network device 102 on the scheduling cell, and the DCI can schedule one or more cells in the cell set.

[0213] Exemplarily, a scheduled cell is a cell scheduled by the above-mentioned scheduling cell, and the scheduled cell belongs to the cell set. It can be understood that a scheduled cell refers to a cell scheduled by the same DCI, and the scheduled cell is one or more cells in the cell set. In one example, the cell set may include at least two types of component carriers, and the at least two types of component carriers include:

[0214] A first type of component carrier, wherein the first type of component carrier supports defining the PDCCH monitoring capability of the terminal based on a span; and

[0215] The second type of component carrier supports the PDCCH monitoring capability of the terminal defined based on time slots.

[0216] Exemplarily, the first type of component carrier may be a Rel-16 CC.

[0217] Exemplarily, the first-category component carrier supports defining the PDCCH monitoring capability of the terminal based on a duration (span), including at least one of the following:

[0218] The terminal 101 counts the number of blind detections (BD) of the PDCCH within a span;

[0219] The terminal 101 counts the number of control channel elements (CCEs) within a span;

[0220] The capability of the terminal 101 to process unicast DCI (unicast DCI) within a span does not exceed the maximum capability of this type of terminal to process unicast DCI as agreed in the protocol.

[0221] Exemplarily, a span includes one or more consecutive Orthogonal Frequency Division Multiplexing symbols (OFDM symbols) belonging to the same time slot.

[0222] Exemplarily, the second type of component carrier may be a Rel-15 CC.

[0223] Exemplarily, the second-type component carrier supports defining the PDCCH monitoring capability of the terminal based on a slot, including at least one of the following:

[0224] The terminal 101 counts the number of BDs of the PDCCH in a slot;

[0225] Terminal 101 counts the number of CCEs in a slot;

[0226] The capability of the terminal 101 to process unicast DCI in one slot does not exceed the maximum capability of this type of terminal to process unicast DCI as agreed in the protocol.

[0227] In some embodiments, the terminal capability information may be used to indicate at least one of the following:

[0228] The component carrier types supported by the terminal;

[0229] The terminal supports a duration combination on a first-type component carrier, where the first-type component carrier supports defining a PDCCH monitoring capability of the terminal 101 based on the duration.

[0230] In one example, the terminal capability information is used to indicate the component carrier type supported by the terminal. For example, when the cell set includes at least two types of component carriers, the terminal 101 supports the first type of component carrier, or the terminal 101 supports the second type of component carrier, or the terminal 101 supports the first type of component carrier and the second type of component carrier.

[0231] In an example, the terminal capability information may be used to indicate a duration combination supported by the terminal on the first type of component carrier.

[0232] For example, a span combination can be expressed as (X, Y), where X is the number of OFDM symbols between the start OFDM symbols of two adjacent spans, and Y is the number of consecutive OFDM symbols included in each span.

[0233] In an example, the terminal capability information may be used to indicate the component carrier types supported by the terminal and the duration combinations supported by the terminal on the first type of component carriers.

[0234] In an example, when the terminal capability information is only used to indicate the duration combination supported by the terminal on the first type of component carrier, it may be assumed that the terminal supports the first type of component carrier.

[0235] In an example, when the terminal capability information is used to indicate that the component carrier types supported by the terminal include first-type component carriers, the terminal capability information is further used to indicate duration combinations supported by the terminal on the first-type component carriers.

[0236] In one example, to reduce the number of bits occupied by terminal capability information, when the terminal supports both the first and second type component carriers, the terminal capability information may be used to indicate that the terminal 101 supports the second type component carrier, and to indicate the duration combination supported by the terminal on the first type component carrier. In this case, after receiving the terminal capability information, the network device 102 may determine that the terminal 101 supports both the first and second type component carriers.

[0237] In some embodiments, the terminal capability information may be used to indicate at least one of the following:

[0238] The component carrier type supported by the terminal on the scheduling cell and / or the scheduled cell;

[0239] The frequency domain range supported by the terminal in the scheduling cell and / or the scheduled cell, whether the supported frequency band belongs to the authorized frequency band, and a combination of one or more of the supported full-duplex communication modes.

[0240] In one example, a scheduling cell is a cell in which the terminal 101 needs to monitor a corresponding search space (SS), and the network device of the scheduling cell can select at least one cell from the cell set for the multi-cell scheduling. It is understandable that the terminal 101 receives DCI sent by the network device 102 on the scheduling cell, and the DCI can schedule one or more cells in the cell set.

[0241] In one example, a scheduled cell is a cell scheduled by the scheduling cell, and the scheduled cell belongs to the cell set. It is understood that a scheduled cell refers to a cell scheduled by the same DCI, and the scheduled cell is one or more cells in the cell set.

[0242] In an example, the terminal 101 may separately report the component carrier types supported by the terminal 101 on the scheduling cell and / or the scheduled cell through the terminal capability information.

[0243] For example, the terminal 101 supports the first type component carrier and the second type component carrier in the scheduling cell, and / or supports the first type component carrier in the scheduled cell.

[0244] In one example, the terminal capability information is used to indicate that the terminal supports at least two types of component carriers on the scheduling cell, for example, a first type component carrier and a second type component carrier. The terminal 101 can determine that the PDCCH monitoring capability supported by itself in the cell set is defined based on the duration, or the terminal 101 can determine that the PDCCH monitoring capability supported by itself in the cell set is defined based on the time slot.

[0245] In one example, the terminal 101 can separately report one or more combinations of the frequency domain range supported by the terminal 101 in the scheduling cell and / or the scheduled cell, whether the supported frequency band belongs to the authorized frequency band, and the supported full-duplex communication mode through the terminal capability information.

[0246] For example, the scheduling cell and the scheduled cell have the same SCS, and / or the terminal 101 supports the same carrier type in the scheduling cell and the scheduled cell, and the terminal 101 reports the terminal capability information, and the content indicated by the terminal capability information is any one of the following:

[0247] Frequency range 1 (FR1) licensed Frequency Division Duplex (FDD);

[0248] Frequency range 1 (FR1) licensed Time Division Duplex (TDD);

[0249] Frequency range 1 (FR1) unlicensed Time Division Duplex (TDD);

[0250] Frequency range 2-1 (FR2-1);

[0251] Frequency range 2-2 (FR2-2).

[0252] For another example, the scheduling cell and the scheduled cell have different SCSs, and / or the terminal 101 supports different carrier types in the scheduling cell and the scheduled cell. The terminal 101 reports the terminal capability information, and the terminal capability information is indicated according to the scheduling cell and the scheduled cell respectively, and the contents indicated are any one of the following: FR1 licensed FDD; FR1 licensed TDD; FR1 unlicensed TDD; FR2-1; FR2-2.

[0253] For example, the terminal capability information is used to indicate that the terminal 101 supports FR1 licensed FDD in the scheduling cell and supports FR1 unlicensed TDD in the scheduled cell.

[0254] In one example, the terminal 101 can refine the reporting granularity when reporting the frequency domain range supported on the scheduling cell and / or the scheduled cell, whether the supported frequency band belongs to the authorized frequency band, and a combination of one or more of the supported full-duplex communication modes, that is, the component carrier types supported by the terminal 101 on the scheduling cell and / or the scheduled cell are reported simultaneously through the same terminal capability information.

[0255] For example, the terminal capability information is used to indicate any one of the following: Rel-15 FR1 licensed FDD; Rel-15 FR1 licensed TDD; Rel-16 FR1 licensed FDD; Rel-16 FR1 licensed TDD.

[0256] Rel-15 corresponds to the second type of component carrier, and Rel-16 corresponds to the first type of component carrier.

[0257] The above description is merely an example. When the terminal capability information indicates that the cell set includes at least two types of component carriers, the content of the physical downlink control channel (PDCCH) monitoring capability supported by the terminal shall fall within the protection scope of the present disclosure.

[0258] In step S2202 , the network device 102 sends configuration information to the terminal 101 based on the terminal capability information.

[0259] In some embodiments, terminal 101 receives the configuration information.

[0260] In some embodiments, the configuration information is used to configure the SS that the terminal 101 monitors on the scheduling cell. The SS is used to transmit the PDCCH.

[0261] In some embodiments, network device 102 determines, based on the terminal capability information, the PDCCH monitoring capability supported by terminal 101 in the cell set when the cell set includes at least two types of component carriers, and further configures an SS for terminal 101 to monitor in the scheduling cell based on the PDCCH monitoring capability supported by terminal 101 in the cell set.

[0262] In some embodiments, the terminal capability information is used to indicate at least one of the following:

[0263] component carrier types supported by the terminal;

[0264] The terminal supports a duration combination on a first-type component carrier, and the first-type component carrier supports defining the PDCCH monitoring capability of the terminal based on duration.

[0265] In one example, the terminal capability information is used to indicate that the component carrier type supported by the terminal is a first-class component carrier, and the terminal capability information does not indicate the duration combination supported by the terminal on the first-class component carrier. When the network device 102 determines that the cell set includes at least two types of component carriers, the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration. Furthermore, the network device 102 can configure SS for the terminal 101 based on any duration combination.

[0266] For example, the network device 102 may configure an SS for the terminal 101 based on any one of the duration combinations (2, 2), (4, 3), and (7, 3).

[0267] In one example, the terminal capability information is used to indicate that the component carrier type supported by the terminal is a second-class component carrier. When the network device 102 determines that the cell set includes at least two types of component carriers, the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the time slot. Furthermore, the network device 102 can configure SS for the terminal 101 based on each time slot.

[0268] In one example, the terminal capability information is used to indicate that the component carrier types supported by the terminal are the first type component carrier and the second type component carrier, and the terminal capability information does not indicate the duration combination supported by the terminal on the first type component carrier. The network device 102 can determine that when the cell set includes at least two types of component carriers, the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration. Further, the network device 102 can configure SS for the terminal 101 based on any duration combination.

[0269] Alternatively, the terminal capability information is used to indicate that the component carrier types supported by the terminal are the first type component carrier and the second type component carrier, and the terminal capability information does not indicate the duration combination supported by the terminal on the first type component carrier. When the network device can determine that the cell set includes at least two types of component carriers, the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the time slot. Further, the network device 102 can configure SS for the terminal 101 based on each time slot.

[0270] In one example, the terminal capability information is used to indicate the duration combination supported by the terminal on the first type of component carrier. The network device 102 defaults to that the terminal 101 supports the first type of component carrier. The network device can determine that when the cell set includes at least two types of component carriers, the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration. Further, the network device 102 can configure SS for the terminal 101 based on the duration combination indicated by the terminal capability information.

[0271] In an example, the terminal capability information is used to indicate the component carrier types supported by the terminal and the duration combinations supported by the terminal on the first type of component carriers.

[0272] When the terminal capability information is used to indicate that the terminal 101 supports the first type of component carrier, the network device 102 can determine that the cell set includes at least two types of component carriers, and the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration. Further, the network device 102 can configure SS for the terminal 101 based on the duration combination indicated by the terminal capability information.

[0273] Alternatively, when the terminal capability information is used to indicate that the terminal 101 supports the second type of component carrier, and the terminal capability information indicates the duration combination supported by the terminal on the first type of component carrier, the network device 102 determines that the terminal 101 supports both the first type of component carrier and the second type of component carrier, and the network device can determine that the cell set includes at least two types of component carriers, the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration or time slot. Further, the network device 102 can configure SS for the terminal 101 based on the duration combination indicated by the terminal capability information or on a time slot basis.

[0274] Alternatively, when the terminal 101 supports the first type of component carrier and the second type of component carrier, and the terminal capability information indicates the duration combination supported by the terminal on the first type of component carrier, the network device 102 determines that the terminal 101 supports both the first type of component carrier and the second type of component carrier. When the network device can determine that the cell set includes at least two types of component carriers, the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration or time slot. Further, the network device 102 can configure SS for the terminal 101 based on the duration combination indicated by the terminal capability information or on a time slot basis.

[0275] In some embodiments, the terminal capability information is used to indicate at least one of the following:

[0276] The component carrier type supported by the terminal on the scheduling cell and / or the scheduled cell;

[0277] The frequency domain range supported by the terminal in the scheduling cell and / or the scheduled cell, whether the supported frequency band belongs to the authorized frequency band, and a combination of one or more of the supported full-duplex communication modes.

[0278] In one example, the terminal capability information is used to indicate the component carrier type supported by the terminal in the scheduling cell. Considering that the terminal 101 will monitor the search space in the scheduling cell, the network device 102 can determine the PDCCH monitoring capability supported by the terminal 101 in the cell set according to the component carrier type supported by the terminal 101 in the scheduling cell, and then configure the SS for the terminal 101.

[0279] For example, the component carrier type supported by the terminal 101 in the scheduling cell is the first type component carrier, and the network device 102 determines that the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration. The network device 102 can configure the SS for the terminal 101 based on any one of the duration combinations (2, 2), (4, 3), and (7, 3).

[0280] For another example, the component carrier type supported by the terminal 101 in the scheduling cell is a second-type component carrier, and the network device 102 may configure an SS for the terminal 101 based on each time slot.

[0281] In one example, the terminal capability information is used to indicate that the terminal supports at least two types of component carriers on the scheduling cell, for example, a first type component carrier and a second type component carrier. The network device 102 can determine that the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration, or the network device 102 can determine that the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the time slot.

[0282] It should be noted that the network device 102 and the terminal 101 need to maintain a consistent understanding of the PDCCH monitoring capability supported by the terminal 101. For example, when the terminal supports the first type component carrier and the second type component carrier in the scheduling cell, the network device 102 and the terminal 101 both believe that the PDCCH monitoring capability supported by the terminal 101 in the cell set is based on the duration definition, or the network device 102 and the terminal 101 both believe that the PDCCH monitoring capability supported by the terminal 101 in the cell set is based on the time slot definition.

[0283] In one example, the terminal capability information is used to indicate the component carrier type supported by the terminal in the scheduled cell. The network device 102 may consider that the component carrier type supported by the scheduling cell is the same as the component carrier type supported by the scheduled cell. In this case, the network device determines the PDCCH monitoring capability supported by the terminal 101 in the cell set based on the duration or time slot definition according to the component carrier type supported by the terminal 101 in the scheduled cell, and then configures the SS for the terminal 101. The configuration method is similar to the method in which the network device 102 configures the SS for the terminal 101 based on the component carrier type supported by the terminal in the scheduling cell, and will not be repeated here.

[0284] In one example, the terminal capability information is used to indicate the component carrier types supported by the terminal in the scheduling cell and the scheduled cell. When the component carrier types supported by the terminal 101 in the scheduling cell and the scheduled cell are the same and are both first-class component carriers, the network device 102 can determine that the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration, and the network device 102 can configure SS for the terminal 101 based on any one of the duration combinations (2, 2), (4, 3), and (7, 3).

[0285] Alternatively, when the component carrier types supported by terminal 101 in the scheduling cell and the scheduled cell are the same, both being second-class component carriers, network device 102 can determine that the PDCCH monitoring capability supported by terminal 101 in the cell set is based on the time slot definition, and network device 102 can configure SS for terminal 101 based on each time slot.

[0286] Alternatively, when the terminal 101 supports the same component carrier type in the scheduling cell and the scheduled cell, including first-class component carriers and second-class component carriers, the network device 102 can determine that the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration or time slot, and the network device 102 can configure SS for the terminal 101 based on any combination of durations or each time slot.

[0287] In one example, the terminal capability information is used to indicate the component carrier type supported by the terminal in the scheduling cell and / or the scheduled cell. When the component carrier types supported by the terminal 101 in the scheduling cell and the scheduled cell are different, considering that the terminal 101 monitors the search space in the scheduling cell, the network device 102 can determine the PDCCH monitoring capability supported by the terminal 101 in the cell set based on the duration or time slot definition based on the component carrier type supported by the scheduling cell, and then configure SS for the terminal 101.

[0288] For example, the scheduling cell supports the first type of component carrier, and the scheduled cell supports the second type of component carrier. The network device 102 can determine the PDCCH monitoring capability supported by the terminal 101 in the cell set based on the duration definition based on the component carrier type supported by the scheduling cell, and then configure the SS for the terminal 101 based on any duration combination.

[0289] In one example, the terminal capability information is used to indicate the component carrier type supported by the terminal in the scheduling cell and / or the scheduled cell. When the component carrier types supported by the terminal 101 in the scheduling cell and the scheduled cell are different, if the first type of component carrier type is supported in the scheduling cell and the second type of component carrier type is supported in the scheduled cell, the network device 102 may also determine the PDCCH monitoring capability supported by the terminal 101 in the cell set based on the time slot definition based on the component carrier type supported by the scheduled cell, and then configure the SS for the terminal 101 based on each time slot.

[0290] For example, the scheduling cell supports the first type of component carrier and the scheduled cell supports the second type of component carrier. The network device 102 can configure the SS for the terminal 101 based on the component carrier type supported by the scheduled cell, that is, based on each time slot.

[0291] In one example, the terminal capability information is used to indicate the component carrier type supported by the terminal in the scheduling cell and / or the scheduled cell. When the component carrier types supported by the terminal 101 in the scheduling cell and the scheduled cell are different, if the terminal 101 supports the second type of component carrier type in the scheduling cell and the first type of component carrier type in the scheduled cell, then the network device 102 may also, under certain circumstances, determine the PDCCH monitoring capability supported by the terminal 101 in the cell set based on the duration definition based on the component carrier type supported by the scheduled cell, and then configure SS for the terminal 101 based on any duration combination.

[0292] The specific situation may include, but is not limited to: the terminal 101 is a high-capability terminal, for example, the terminal 101 has higher data processing capabilities than a terminal with only basic data processing capabilities, or other specific situations, which are not limited in this disclosure.

[0293] In one example, the terminal capability information is used to indicate a combination of one or more of the frequency domain range supported by the terminal in the scheduling cell and / or the scheduled cell, whether the supported frequency band belongs to the authorized frequency band, and the supported full-duplex communication mode. The network device 102 determines the PDCCH monitoring capability supported by the terminal 101 in the cell set based on the duration or time slot definition, and can then configure the SS for the terminal 101 based on any combination of durations or each time slot.

[0294] In one example, the terminal capability information is used to indicate the component carrier type supported by the terminal on the scheduling cell and / or the scheduled cell; and a combination of one or more of the frequency domain range supported by the terminal on the scheduling cell and / or the scheduled cell, whether the supported frequency band belongs to the authorized frequency band, and the supported full-duplex communication mode.

[0295] The network device 102 may configure an SS for the terminal 101 according to the component carrier types supported by the scheduling cell and the scheduled cell. The specific configuration method has been introduced in the above embodiment and will not be repeated here.

[0296] It should also be noted that when the network device 102 configures the SS, it should ensure that the number of BDs of the PDCCH by the terminal 101 in each duration or each time slot is less than or equal to the first number, and / or that the number of CCEs counted by the terminal 101 in each duration or each time slot is less than or equal to the first number, and / or that the ability of the terminal 101 to process unicast DCI in each duration or each time slot does not exceed the maximum capability of this type of terminal in unicast DCI.

[0297] Among them, the first digit, the first number, and the maximum capacity can be agreed upon by the protocol or determined in a predefined manner, and this disclosure does not limit this.

[0298] The above description is merely an exemplary description, and all solutions in which the network device 102 configures the SS for the terminal 101 based on the terminal capability information should fall within the scope of protection of this disclosure.

[0299] In some embodiments, after receiving the configuration information, the terminal 101 may monitor PDCCH candidates in the search space to obtain the PDCCH transmitted by the network device 102 .

For example, step S2201 may be implemented as an independent embodiment, step S2202 may be implemented as an independent embodiment, and steps S2201+S2202 may be implemented as independent embodiments, but are not limited thereto.

[0307] In some embodiments, step S2201 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 PDCCH monitoring capability supported by the terminal based on terminal capability information sent by other means or other entities, step S2201 may not be performed.

[0308] In some embodiments, step S2202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0309] In some embodiments, steps S2201 to S2202 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0310] In the above embodiment, the terminal can report terminal capability information to the network device, informing the network device of the PDCCH monitoring capabilities supported by the terminal when the cell set includes at least two types of component carriers. The network device can configure a search space for the terminal based on the terminal capabilities. This ensures that the network device and the terminal have a consistent understanding of the PDCCH monitoring capabilities supported by the terminal in the cell set, thereby improving the reliability and availability of multi-cell scheduling.

[0311] FIG2C is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2C , the present disclosure embodiment relates to an information transmission method, which includes:

[0312] In step S2301 , the terminal 101 determines the PDCCH monitoring capability supported by the terminal 101 in the cell set based on a predefined method.

[0313] In some embodiments, the set of cells may be a set of scheduled cells.

[0314] Exemplarily, one or more cells in the cell set support being scheduled by the same DCI.

[0315] When the network device 102 performs multi-cell scheduling, it may select one or more cells in the cell set and send scheduling information of the selected cells to the terminal 101 via the same DCI.

[0316] Exemplarily, the cell set may further include a scheduling cell, that is, one cell in the cell set may serve as the scheduling cell, and the other cells in the cell set may serve as the scheduled cells.

[0317] Exemplarily, the scheduling cell does not belong to the cell set, that is, the cell set only includes the scheduled cells, and the scheduling cell may select one or more cells from the cell set for multi-cell scheduling.

[0318] The concepts of the scheduling cell and the scheduled cell have been introduced in the aforementioned embodiments and will not be repeated here.

[0319] In some embodiments, the terminal 101 does not expect the cell set to include at least two types of component carriers at the same time. For example, the terminal 101 does not expect the cell set to include a first type of component carrier and a second type of component carrier.

[0320] Exemplarily, the first type of component carrier may be a Release 16 component carrier.

[0321] Exemplarily, the first-category component carrier supports defining the PDCCH monitoring capability of the terminal based on duration, including at least one of the following:

[0322] The terminal 101 counts the number of BDs of the PDCCH within a span;

[0323] Terminal 101 counts the number of CCEs within a span;

[0324] The capability of the terminal 101 to process unicast DCI within a span does not exceed the maximum capability of this type of terminal to process unicast DCI as agreed upon in the protocol.

[0325] Exemplarily, a span includes one or more consecutive Orthogonal Frequency Division Multiplexing symbols (OFDM symbols) belonging to the same time slot.

[0326] Exemplarily, the second-type component carrier may be a Release 15 component carrier.

[0327] Exemplarily, the second-type component carrier supports defining the PDCCH monitoring capability of the terminal based on time slots, including at least one of the following:

[0328] The terminal 101 counts the number of BDs of the PDCCH in a slot;

[0329] Terminal 101 counts the number of CCEs in a slot;

[0330] The capability of the terminal 101 to process unicast DCI in one slot does not exceed the maximum capability of this type of terminal to process unicast DCI as agreed in the protocol.

[0331] That is, the terminal 101 determines whether a cell set includes only the first type of component carriers or only the second type of component carriers.

[0332] In some embodiments, the terminal 101 determines the physical downlink control channel (PDCCH) monitoring capability supported by the terminal in the cell set in the following manner:

[0333] When the cell set includes at least two types of component carriers, determining the PDCCH monitoring capability supported by the terminal 101 in the cell set is based on a duration definition or a time slot definition;

[0334] When the cell set includes only the first type of component carriers, determining the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration;

[0335] When the cell set includes only the second type of component carriers, the PDCCH monitoring capability supported by the terminal 101 in the cell set is determined based on a time slot definition.

[0336] In an example, when the cell set includes only the first type of component carrier, the PDCCH monitoring capability supported by the terminal 101 in each duration may be additionally defined in a predefined manner.

[0337] In an example, when the cell set includes only the first type component carrier, the terminal 101 can determine that the duration combination supported by the terminal 101 in the cell set is the same as the duration combination on any first type component carrier in the cell set.

[0338] In one example, when terminal 101 determines that at least two types of component carriers are supported on the scheduling cell, for example, a first type component carrier and a second type component carrier, terminal 101 may determine that the PDCCH monitoring capability supported by terminal 101 within the cell set is defined based on a duration, or terminal 101 may determine that the PDCCH monitoring capability supported by terminal 101 within the cell set is defined based on a time slot. In step S2302, network device 102 determines the PDCCH monitoring capability supported by terminal 101 within the cell set based on a predefined method.

[0339] In some embodiments, the network device 102 may configure a cell set for the terminal 101 and ensure that the cell set includes only one type of component carrier through scheduling by the network device.

[0340] For example, the network device 102 may configure a cell set #1 for the terminal 101, which only includes the first type of component carriers.

[0341] For another example, the network device 102 may configure a cell set #2 for the terminal 101, which only includes the second type of component carriers.

[0342] In some embodiments, the network device 102 may determine the PDCCH monitoring capability supported by the terminal 101 in the cell set in the following manner:

[0343] When the cell set includes at least two types of component carriers, determining the PDCCH monitoring capability supported by the terminal 101 in the cell set is based on a duration definition or a time slot definition;

[0344] When the cell set includes only the first type of component carriers, determining the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration;

[0345] When the cell set includes only the second type of component carriers, the PDCCH monitoring capability supported by the terminal 101 in the cell set is determined based on a time slot definition.

[0346] In an example, when the cell set includes only the first type of component carrier, the PDCCH monitoring capability supported by the terminal 101 in each duration may be additionally defined in a predefined manner.

[0347] In an example, when the cell set includes only the first type component carrier, the network device 102 can determine that the duration combination supported by the terminal 101 in the cell set is the same as the duration combination on any first type component carrier in the cell set.

[0348] In one example, when the network device 102 determines that the terminal 101 supports at least two types of component carriers on the scheduling cell, such as a first type component carrier and a second type component carrier, the network device 102 can determine that the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration, or the network device 102 can determine that the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the time slot.

[0349] It should be noted that the network device 102 and the terminal 101 need to maintain a consistent understanding of the PDCCH monitoring capability supported by the terminal 101. For example, when the terminal supports the first type component carrier and the second type component carrier in the scheduling cell, the network device 102 and the terminal 101 both believe that the PDCCH monitoring capability supported by the terminal 101 in the cell set is based on the duration definition, or the network device 102 and the terminal 101 both believe that the PDCCH monitoring capability supported by the terminal 101 in the cell set is based on the time slot definition.

[0350] Step S2303 , the network device 102 sends configuration information to the terminal 101 .

[0351] In some embodiments, terminal 101 receives the configuration information.

[0352] In some embodiments, the configuration information is used to configure the SS that the terminal 101 monitors on the scheduling cell. The SS is used to transmit the PDCCH.

[0353] In some embodiments, network device 102 determines the PDCCH monitoring capability supported by terminal 101 in the cell set based on a predefined method, and then configures an SS for terminal 101 to monitor in the scheduling cell based on the PDCCH monitoring capability supported by terminal 101 in the cell set.

[0354] In some embodiments, the network device 102 configures a cell set for the terminal 101, and the cell set only includes the first type of component carriers. The network device 102 can determine that the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on the duration, and the network device 102 can configure the SS for the terminal 101 based on any combination of durations.

[0355] For example, the network device 102 may configure an SS for the terminal 101 based on any one of the duration combinations (2, 2), (4, 3), and (7, 3).

[0356] In some embodiments, the network device 102 configures a cell set for the terminal 101, and the cell set only includes the second type of component carriers. The network device 102 determines that the PDCCH monitoring capability supported by the terminal 101 in the cell set is based on the time slot definition, and the network device 102 can configure the SS for the terminal 101 based on each time slot.

[0357] In some embodiments, the network device 102 determines, in a predefined manner, that the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on duration, and the network device 102 may configure an SS for the terminal 101 based on any combination of durations.

[0358] In some embodiments, the network device 102 determines, in a predefined manner, that the PDCCH monitoring capability supported by the terminal 101 in the cell set is defined based on a time slot, and the network device 102 may configure an SS for the terminal 101 based on each time slot.

[0359] It should also be noted that when the network device 102 configures the SS, it should ensure that the number of BDs of the PDCCH by the terminal 101 in each duration or each time slot is less than or equal to the first number, and / or that the number of CCEs counted by the terminal 101 in each duration or each time slot is less than or equal to the first number, and / or that the ability of the terminal 101 to process unicast DCI in each duration or each time slot does not exceed the maximum capability of this type of terminal in unicast DCI.

[0360] Among them, the first digit, the first number, and the maximum capacity can be agreed upon by the protocol or determined in a predefined manner, and this disclosure does not limit this.

[0361] The above description is merely an example, and all solutions in which the network device 102 configures the SS for the terminal 101 should fall within the scope of protection of this disclosure.

[0362] In some embodiments, after receiving the configuration information, the terminal 101 may monitor PDCCH candidates in the search space to obtain the PDCCH transmitted by the network device 102 .

[0368] In some embodiments, terms such as "certain", "preseted", "preset", "setting", "indicated", "a certain", "any", "first", and "designated" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0371] In some embodiments, step S2302 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when network device 102 determines the PDCCH monitoring capability supported by terminal 101 within the cell set based on terminal capability information reported by terminal 101 or other entities, step S2302 may not be performed.

[0372] In some embodiments, step S2303 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0438] In the above embodiment, the network device can determine the PDCCH monitoring capability supported by the terminal in the cell set based on a predefined method, and then send configuration information to the terminal to configure a search space for the terminal, thereby improving the reliability and availability of multi-cell scheduling.

[0439] The above process is further illustrated by the following examples:

[0440] In an embodiment of the present disclosure, when a cell set used for multi-cell (or multi-carrier) scheduling includes both version 15 component carriers and version 16 component carriers, the PDCCH monitoring capability of the terminal is determined based on the relevant capabilities reported by the terminal or a predefined method.

[0441] Terminal side:

[0442] When a cell set used for multi-cell scheduling includes both Release 15 component carriers and Release 16 component carriers, the terminal determines or indicates to the base station the maximum number of BDs / CCEs supported by it for scheduling cell combinations in the cell set in the following manner:

[0443] Method 1: Define the maximum number of BDs (i.e., the first number) and / or the maximum number of CCEs (i.e., the first number) supported by the terminal in each span on the scheduling cell of the cell set. The terminal reports the terminal capabilities to the base station. The capabilities include at least one of the following:

[0444] The terminal reports the component carrier types it supports;

[0445] Duration combinations supported by the terminal on the first type of component carrier.

[0446] When a cell set includes both Rel-15 CCs and Rel-16 CCs, the BD and / or CCE processing capability of the terminal is determined according to each span.

[0447] Method 2: Define terminal behavior. The terminal does not expect the following situations to occur:

[0448] The cell set includes both Rel-16 CC and Rel-15 CC.

[0449] That is, all terminals in the cell set only support Rel-15 CC or Rel-16 CC.

[0450] Method 3: The terminal determines its BD and / or CCE processing capabilities for the cell set according to a predefined method

[0451] In this method, the terminal does not impose any restrictions on the composition of cells within the cell set. The terminal and network equipment determine the relevant capabilities and configurations as follows:

[0452] When a cell set contains both Rel-16 CCs and Rel-15 CCs, it is treated as if the cell set consists entirely of Rel-16 CCs or entirely of Rel-15 CCs.

[0453] When the cell set contains only Rel-15 CC, it is processed according to Rel-15 CC;

[0454] When the cell set contains only Rel-16 CCs and the terminal reports FG 11 related capabilities, it is processed according to Rel-16 CCs.

[0455] At this time, you can additionally define the terminal's capabilities per span.

[0456] Method 4: When reporting the scheduling cell and co-scheduled cell types, the terminal refines the reporting granularity of the scheduling cell and co-scheduled cell types, that is, adds the distinction between Rel-15 and Rel-16 types.

[0457] Specifically, after reporting the scheduling cell and co-scheduled cell types, that is, {FR1 licensed FDD, FR1 licensed TDD, FR1 unlicensed TDD, FR2-1, FR2-2}, the terminal additionally reports the co-scheduled cell as Rel-15 CC or Rel-16 CC.

[0458] On the network device side:

[0459] When a cell set used for multi-carrier (MC) scheduling includes both Rel-15 CCs and Rel-16 CCs, the network device determines the maximum number of BDs (first number) and / or the maximum number of CCEs (first number) supported by the terminal for scheduling a cell combination in the cell set in the following manner, and ensures that the number of BDs and CCEs that the terminal needs to blindly detect in all search spaces configured on the scheduling cell does not exceed the terminal capability limit.

[0460] Method 1: The network device receives corresponding capabilities reported by the terminal, where the terminal capabilities indicate the maximum number of BDs and / or the maximum number of CCEs supported by the terminal in each span on a scheduling cell of a cell set.

[0461] Method 2: The cell set configured by the network device for the terminal only contains Rel-15 CC or Rel-16 CC.

[0462] Method 3: The network device determines the maximum number of BDs and / or the maximum number of CCEs supported by the terminal according to a predefined method.

[0463] Method 4: The network device receives the scheduling cell and co-scheduled cell types reported by the terminal, and uses them to determine the maximum number of BDs and / or the maximum number of CCEs supported by the terminal.

[0464] The terminal capability notifies the base station that the supported scheduling cell is Rel-15 CC or Rel-16 CC;

[0465] The terminal capability notifies the base station that the co-scheduled cell supported by the terminal is a Rel-15 CC or a Rel-16 CC.

[0466] In Example 1, it is assumed that the terminal is a Rel-18 or later version terminal and supports multi-cell 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. The MC UE supports the following features:

[0467] A maximum of four cell sets are supported in one Physical Uplink Control Channel (PUCCH) group.

[0468] In a cell set, up to 4 cells can be scheduled through one DCI.

[0469] 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 cell set includes Rel-15 CC and Rel-16 CC, which are defined as follows:

[0470] Rel-15 CC means that the terminal processes BD and / or CCE on a per-slot basis.

[0471] Rel-16 CC means that the terminal processes BD and / or CCE on the CC according to each duration (per span).

[0472] The BD times limit per span is shown in Table 1.

[0473] Table 1

[0474] Among them, μ is used to indicate the subcarrier spacing. The subcarrier spacing of a cell is 15×2^μ kilohertz (kHz). The value of μ can be 0 or 1. When the value of μ is 0, the subcarrier spacing of the cell is 15 kHz. When the value of μ is 1, the subcarrier spacing of the cell is 30 kHz.

[0475] The limit on the number of CCEs per span is shown in Table 2.

[0476] Table 2

[0477] Among them, μ is used to indicate the subcarrier spacing. The subcarrier spacing of a cell is 15×2^μ kilohertz (kHz). The value of μ can be 0 or 1. When the value of μ is 0, the subcarrier spacing of the cell is 15 kHz. When the value of μ is 1, the subcarrier spacing of the cell is 30 kHz.

[0478] In this embodiment, the terminal's capabilities regarding the maximum number of BDs and / or the maximum number of CCEs supported by the terminal within each span of a scheduling cell in a cell set are defined. The terminal reports these capabilities to the base station to indicate its support for MC scheduling. Furthermore, when a cell set includes both Rel-15 CCs and Rel-16 CCs, the terminal's capabilities regarding the maximum number of BDs / CCEs associated with the cell set are also defined.

[0479] In this embodiment, it is assumed that the terminal capabilities include at least the following:

[0480] The terminal reports the CC types and / or span combinations supported by it.

[0481] Specifically, although the cell set configured by the network for MC scheduling for the terminal includes both Rel-15 CCs and Rel-16 CCs, the terminal can report the following terminal capabilities to the network:

[0482] 1) The terminal reports that its supported CC capability is Rel-15 CC or Rel-16 CC.

[0483] When the CC capability reported by the terminal to the network is Rel-15 CC, the base station can only configure a search space for the terminal to transmit PDCCH on the scheduling cell based on the per slot BD / CCE limit;

[0484] When the CC capability reported by the terminal to the network is Rel-16, the base station needs to configure the search space for the terminal to transmit PDCCH on the scheduling cell according to the per span BD / CCE limit. When the terminal reports Rel-16 CC capability to the network but does not report the corresponding span combination, it means that the terminal supports the span combination supported by any Rel-16 CC included in the cell set.

[0485] 2) The terminal may additionally report span combination capabilities, namely, the BD / CCE limits within the spans supported by Tables 1 and 2. After the terminal reports the span combination, the network may configure a search space for the terminal on the scheduling cell based on the span combination. The span combination-related capabilities may differ from any Rel-16 CC capabilities belonging to the cell set.

[0486] In Example 2, it is assumed that the terminal is a Rel-18 or later version terminal and supports multi-cell scheduling, that is, it supports scheduling data transmission on multiple cells through one DCI. In this embodiment, the terminal is called an MC UE. The MC UE supports the following features:

[0487] A maximum of 4 cell sets are supported in one PUCCH group;

[0488] In a cell set, up to 4 cells can be scheduled through one DCI.

[0489] 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 cell set includes Rel-15 CC and Rel-16 CC, which are defined as follows:

[0490] Rel-15 CC means that the terminal processes BD and / or CCE on a per-slot basis;

[0491] Rel-16 CC means that the terminal processes BD and / or CCE on a per span basis.

[0492] The number of BDs per span is limited as shown in Table 1. The number of CCEs per span is limited as shown in Table 2.

[0493] In this embodiment, the MC terminal does not expect the following situations:

[0494] The cell set contains both Rel-16 CCs and Rel-15 CCs, that is, all terminals in the cell set can only be Rel-15 CCs or Rel-16 CCs.

[0495] Correspondingly, when configuring a cell set for a terminal, the base station ensures that all CCs in the cell set are Rel-15 CCs or Rel-16 CCs.

[0496] When all CCs in the cell set are Rel-15 CCs, the base station configures a search space for the MC UE based on the per-slot BD / CCE limit. When all CCs in the cell set are Rel-16 CCs, the base station configures a search space for the MC UE based on the per-span BD / CCE limit. When the base station configures a search space for the MC UE based on the per-span BD / CCE limit, the per-span BD / CCE limit followed is determined by any span combination reported by the terminal.

[0497] In Example 3, it is assumed that the terminal is a Rel-18 or later version terminal and supports MC scheduling, that is, it supports scheduling data transmission on multiple cells through one DCI. In this embodiment, the terminal is called an MC UE. The MC UE supports the following features:

[0498] A maximum of 4 cell sets are supported in one PUCCH group;

[0499] In a cell set, up to 4 cells can be scheduled through one DCI.

[0500] 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 cell set includes Rel-15 CC and Rel-16 CC, which are defined as follows:

[0501] Rel-15 CC means that the terminal processes BD / CCE on a per-slot basis;

[0502] Rel-16 CC means that the terminal processes BD / CCE on a per span basis.

[0503] The number of BDs per span is limited as shown in Table 1. The number of CCEs per span is limited as shown in Table 2.

[0504] In this embodiment, the network device and the MC terminal determine the BD / CCE capability of the MC terminal for the cell set according to a predefined method.

[0505] Specifically, the terminal and network device sides do not impose any restrictions on the CC types included in the cell set, that is, the cell set can support any combination of the following cell types:

[0506] The cell set only contains Rel-15 CC;

[0507] The cell set only contains Rel-16 CCs;

[0508] The cell set includes both Rel-15 CC and Rel-16 CC.

[0509] When the cell set contains both Rel-15 CCs and Rel-16 CCs, the cell set is treated as if it is entirely Rel-16 CCs or entirely Rel-15 CCs. That is, when configuring the terminal's search space, the per span limit or per slot limit is used to ensure that the PDCCH configuration does not exceed the BD / CCE capacity limit.

[0510] When the cell set only includes Rel-15 CCs, the search space is configured according to the Rel-15 CCs, that is, the network side follows the per slot limit to ensure that the PDCCH configuration does not exceed the BD / CCE capacity upper limit.

[0511] When the cell set only includes Rel-16 CCs, the search space is configured according to the Rel-16 CC process. That is, the network side follows the per slot limit to ensure that the PDCCH configuration does not exceed the BD / CCE capacity limit. The span combination of the Rel-16 CC can be a span combination on any CC included in the cell set.

[0512] In Example 4, it is assumed that the terminal is a Rel-18 or later version terminal and supports MC scheduling, that is, it supports scheduling data transmission on multiple cells through one DCI. In this embodiment, the terminal is called an MC UE. The MC UE supports the following features:

[0513] A maximum of 4 cell sets are supported in one PUCCH group;

[0514] In a cell set, up to 4 cells can be scheduled through one DCI.

[0515] 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 cell set includes Rel-15 CC and Rel-16 CC, which are defined as follows:

[0516] Rel-15 CC means that the terminal processes BD / CCE on a per-slot basis;

[0517] Rel-16 CC means that the terminal processes BD / CCE on a per span basis.

[0518] The number of BDs per span is limited as shown in Table 1. The number of CCEs per span is limited as shown in Table 2.

[0519] In this embodiment, when reporting the scheduling cell and scheduled cell types, the terminal refines the reporting granularity to distinguish between Rel-15 CCs and Rel-16 CCs. The base station determines the BD / CCE capability that the terminal can handle based on the carrier type reported by the terminal and configures the search space for the terminal on the scheduling cell based on this capability.

[0520] Specifically, the terminal can report the carrier types it supports according to the following granularity:

[0521] Report the carrier type of the scheduling cell and scheduled cell separately. The specific carrier type includes at least one of the following:

[0522] Rel-15 FR1 licensed FDD;

[0523] Rel-15 FR1 licensed TDD;

[0524] Rel-16 FR1 licensed FDD;

[0525] Rel-16 FR1 licensed TDD.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.
