[0156] In some embodiments, the core network device 102-2 may be a device including one or more network elements, or may be multiple devices or a group of devices. The network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0158] In some embodiments, in some embodiments, the terminal 101 is connected to the core network device 102-2 through the access network device 102-1.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] 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:

[0164] On Rel-15 CCs, the terminal supports slot-level PDCCH monitoring capabilities.

[0165] On the Rel-16 CC, the terminal supports a span-level PDCCH monitoring capability.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] Specifically, the terminal can report the following three terminal capabilities:

[0170] Pure Rel-15 CC;

[0171] Pure Rel-16 CC;

[0172] Rel-15 CC+Rel-16 CC.

[0173] However, since the capability reporting and configuration of Rel-16 CC and Rel-15 CC are isolated, the DCI processing capability supported by the terminal will be ambiguous during multi-cell scheduling.

[0174] 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:

[0175] 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}.

[0176] 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}.

[0177] Although terminal capabilities define the types of scheduling and co-scheduling cells reported, 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 configuration cannot be performed based on the terminal's DCI processing capabilities defined based on duration.

[0178] To address the issue of ambiguity regarding the DCI processing 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 DCI processing capabilities supported by the terminal within a set of cells, improving the reliability of DCI configuration and, consequently, the reliability and availability of multi-cell scheduling.

[0179] 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:

[0180] Step S2101 : Terminal 101 sends terminal capability information to network device 102 .

[0181] In some embodiments, the network device 102 receives the terminal capability information.

[0182] In some embodiments, the name of the terminal capability information is not limited.

[0183] In some embodiments, the terminal capability information is used to indicate the DCI processing capability supported by the terminal in a cell set when the cell set includes at least two types of CCs.

[0184] In one example, a set of cells may be used for multi-cell scheduling.

[0185] Exemplarily, one or more cells in the cell set support being scheduled by the same DCI.

[0186] 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.

[0187] In an example, the cell set may include at least two types of component carriers, where the at least two types of component carriers include:

[0188] A first type of component carrier, wherein the first type of component carrier supports defining a DCI processing capability of a terminal based on a duration (span); and

[0189] The second type of component carrier supports defining the DCI processing capability of the terminal based on time slots.

[0190] Exemplarily, the first type of component carrier may be a Rel-16 CC.

[0191] Exemplarily, the first-category component carrier supports defining the DCI processing capability of the terminal based on a duration (span), including at least one of the following:

[0192] The capability of terminal 101 to process DCI (unicast DCI) within a span does not exceed the maximum capability of this type of terminal to process DCI as agreed upon 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 DCI processing capability of the terminal based on a time slot (slot), including at least one of the following:

[0196] The capability of the terminal 101 to process DCI in one slot does not exceed the maximum capability of this type of terminal to process DCI as agreed upon in the protocol.

[0197] In some embodiments, the terminal 101 may determine the size of the first time window based on the duration required to process a maximum number of DCIs.

[0198] In one example, the present disclosure does not limit the above maximum number.

[0199] Exemplarily, the maximum number of DCIs supported by the terminal for processing on a frequency division duplex (FDD) carrier includes: one downlink DCI and one uplink DCI, wherein the downlink DCI refers to DCI for scheduling downlink data, and the uplink DCI refers to DCI for scheduling uplink data.

[0200] For example, the maximum number of DCIs supported by the terminal on a time division duplex (TDD) carrier includes: one downlink DCI and two uplink DCIs, wherein the downlink DCI refers to the DCI used to schedule downlink data, and the uplink DCI refers to the DCI used to schedule uplink data.

[0201] The terminal 101 may determine the duration required to process the maximum number of DCIs as the duration of the first time window, and inform the network device of the duration.

[0202] Exemplarily, the terminal capability information sent by the terminal 101 may be used to indicate: the size of the first time window.

[0203] Exemplarily, the terminal capability information may be used for any of the following:

[0204] A duration combination corresponding to the first time window;

[0205] The number of consecutive time units occupied by the first time window.

[0206] 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.

[0207] In some embodiments, the duration can also be understood as a time span, and the duration combination can be represented by multiple continuous or non-continuous time periods.

[0208] The terminal 101 may inform the network device 102 of the continuous combined duration corresponding to the first time window for processing the maximum number of DCIs by the terminal 101 through the terminal capability information, so that the network device 102 determines each first time window, ie, each continuous duration.

[0209] Exemplarily, the terminal 101 may inform the network device 102 of the number N of consecutive time units occupied by the first time window for the terminal 101 to process the maximum number of DCIs through the terminal capability information.

[0210] The time unit may be a time slot, an OFDM symbol, or the like. For example, the first time window may occupy N consecutive time slots, or the first time window may occupy N consecutive OFDM symbols.

[0211] In some embodiments, the terminal capability information may be used to indicate at least one of the following:

[0212] The component carrier type supported by the terminal on the scheduling cell and / or the scheduled cell;

[0213] 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.

[0214] In one example, a scheduling cell is at least one cell within the cell set used for performing the multi-cell scheduling. Terminal 101 needs to monitor the corresponding search space (SS) on the scheduling cell, 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 terminal 101 receives DCI sent by network device 102 on the scheduling cell, and the DCI can schedule one or more cells within the cell set.

[0215] 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 that can be scheduled by the same DCI, and the scheduled cell is one or more cells in the cell set.

[0216] When a scheduling cell schedules multiple scheduled cells through the same DCI, the multiple scheduled cells may be referred to as co-scheduled cells.

[0217] In an example, the cell set may include a scheduling cell and a scheduled cell, that is, the scheduling cell may belong to the cell set.

[0218] In an example, the scheduling cell may be one of the scheduled cells, or the scheduling cell may be different from any of the scheduled cells.

[0219] For example, a cell set includes cell #1, cell #2, and cell #3. A terminal monitors DCI #1 in cell #1, which carries scheduling information for both cells #1 and #2. In this case, cell #1 is the scheduling cell, and cells #1 and #2 are the scheduled cells. In this case, the scheduling cell schedules itself and other cells in the cell set.

[0220] For another example, a cell set includes cell #1, cell #2, and cell #3. A terminal monitors DCI on cell #1, and DCI #2 carries scheduling information for cells #2 and #3. In this case, cell #1 is the scheduling cell, and cells #2 and #3 are the scheduled cells. In this case, the scheduling cell schedules other cells in the cell set.

[0221] The above description is merely an example. The case where the scheduling cell does not belong to the cell set should also fall within the protection scope of the present disclosure.

[0222] 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.

[0223] 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.

[0224] 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.

[0225] 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:

[0226] Frequency range 1 (FR1) licensed Frequency Division Duplex (FDD);

[0227] Frequency range 1 (FR1) licensed Time Division Duplex (TDD);

[0228] Frequency range 1 (FR1) unlicensed time division duplex (TDD);

[0229] Frequency range 2-1 (FR2-1);

[0230] Frequency range 2-2 (FR2-2).

[0231] 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.

[0232] 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.

[0233] 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.

[0234] 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.

[0235] Rel-15 corresponds to the second type of component carrier, and Rel-16 corresponds to the first type of component carrier.

[0236] The above description is merely an exemplary description. When the terminal capability information indicates that the cell set includes at least two types of component carriers, the contents of the DCI processing capabilities supported by the terminal should all fall within the protection scope of the present disclosure.

[0237] Step S2102: The network device 102 determines the DCI processing capability supported by the terminal 101 in the cell set based on the terminal capability information.

[0238] In some embodiments, network device 102 receives terminal capability information indicating the size of the first time window. Accordingly, network device 102 may determine that the DCI processing capability supported by the terminal in the cell set is: supporting processing of the maximum number of DCIs in the first time window.

[0239] The present disclosure does not limit the maximum number.

[0240] In one example, the terminal capability information is used to indicate a duration combination corresponding to a first time window, and the network device 102 determines the size of the first time window as the span indicated by the duration combination based on the terminal capability information. Accordingly, the network device 102 can determine that the DCI processing capability supported by the terminal in the cell set is: supporting the processing of the maximum number of DCIs in each determined span.

[0241] In one example, the terminal capability information is used to indicate the number N of consecutive time units occupied by the first time window. The network device 102 determines the size of the first time window as N consecutive OFDM symbols occupied in the same time slot based on the terminal capability information. Accordingly, the network device 102 can determine that the DCI processing capability supported by the terminal in the cell set is: supporting the processing of the maximum number of DCIs within the determined N consecutive OFDM symbols.

[0242] In some embodiments, the network device 102 receives terminal capability information, where the terminal capability information is used to indicate at least one of the following: the component carrier type supported by the terminal on the scheduling cell and / or the scheduled cell; the scheduled cell belongs to the cell set; 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 one or more combinations of the supported full-duplex communication mode; the scheduled cell belongs to the cell set. The network device 102 can then determine the DCI processing capability supported by the terminal 101 within the cell set in the following manner:

[0243] Exemplarily, the terminal capability information is used to indicate the component carrier type supported by the terminal on the scheduling cell. Assuming it is a first-class component carrier, the network device determines that the DCI processing capability supported by the terminal 101 in the cell set is: supporting the processing of a specified number of DCIs in each span.

[0244] The specified number may be less than or equal to the aforementioned maximum number, and this disclosure does not limit this.

[0245] The network device 102 may determine the span occupied by each first time window based on any span combination.

[0246] For example, the network device 102 may determine the span occupied by each first time window based on any one of the duration combinations (2, 2), (4, 3), and (7, 3).

[0247] Exemplarily, the terminal capability information is used to indicate the component carrier type supported by the terminal on the scheduling cell. Assuming it is a second-class component carrier, the network device determines that the DCI processing capability supported by the terminal 101 in the cell set is: supporting processing of a specified number of DCIs in each time slot.

[0248] The specified number may be less than or equal to the aforementioned maximum number, and this disclosure does not limit this.

[0249] Exemplarily, the terminal capability information is used to indicate the component carrier type supported by the terminal on the scheduling cell. Assuming it is a first-class component carrier and a second-class component carrier, the network device determines that the DCI processing capability supported by the terminal 101 in the cell set is: supporting the processing of a specified number of DCIs in each span, or supporting the processing of a specified number of DCIs in each slot.

[0250] The specified number may be less than or equal to the aforementioned maximum number, and this disclosure does not limit this.

[0251] The network device 102 may determine the span occupied by each first time window based on any span combination.

[0252] For example, the network device 102 may determine the span occupied by each first time window based on any one duration combination of (2, 2), (4, 3), and (7, 3).

[0253] Exemplarily, the terminal capability information is used to indicate the component carrier type supported by the terminal on the scheduled cell. Assuming it is a first-class component carrier, the network device 102 may assume that the component carrier type supported by the terminal 101 on the scheduling cell is the same as the component carrier type supported on the scheduled cell. The network device 102 determines that the DCI processing capability supported by the terminal 101 in the cell set is: supporting the processing of a specified number of DCIs in each span.

[0254] Exemplarily, the terminal capability information is used to indicate the component carrier type supported by the terminal on the scheduled cell. Assuming it is a second-class component carrier, the network device 102 may assume that the component carrier type supported by the terminal 101 on the scheduling cell is the same as the component carrier type supported on the scheduled cell. The network device 102 then determines that the DCI processing capability supported by the terminal 101 in the cell set is: supporting the processing of a specified number of DCIs in each slot.

[0255] Exemplarily, the terminal capability information is used to indicate the component carrier type supported by the terminal on the scheduled cell. Assuming it is a first-class component carrier and a second-class component carrier, the network device 102 may assume that the component carrier type supported by the terminal 101 on the scheduling cell is the same as the component carrier type supported on the scheduled cell. The network device 102 determines that the DCI processing capability supported by the terminal 101 in the cell set is: supporting the processing of a specified number of DCIs in each span, or supporting the processing of a specified number of DCIs in each slot.

[0256] Exemplarily, the terminal capability information is used to indicate the component carrier types supported by the terminal in the scheduling cell and the scheduled cell. Assuming that the supported component carrier types are the same, for example, both support the first type of component carrier, the network device 102 determines that the DCI processing capability supported in the cell set of the terminal 101 is: supporting the processing of a specified number of DCIs in each span.

[0257] Exemplarily, the terminal capability information is used to indicate the component carrier types supported by the terminal in the scheduling cell and the scheduled cell. Assuming that the supported component carrier types are the same, for example, both support the second type of component carrier, the network device 102 determines that the DCI processing capability supported in the cell set of the terminal 101 is: supporting the processing of a specified number of DCIs in each slot.

[0258] Exemplarily, the terminal capability information is used to indicate the component carrier types supported by the terminal in the scheduling cell and the scheduled cell. Assuming that the supported component carrier types are the same, for example, both support the first type of component carrier and the second type of component carrier, the network device 102 determines that the DCI processing capability supported in the cell set of the terminal 101 is: supporting the processing of a specified number of DCIs in each span, or supporting the processing of a specified number of DCIs in each slot.

[0259] Exemplarily, the terminal capability information is used to indicate the component carrier types supported by the terminal in the scheduling cell and the scheduled cell. Assuming that the supported component carrier types are different, and considering that the terminal 101 monitors DCI in the scheduling cell, the network device 102 can determine the DCI processing capability supported by the terminal 101 within the cell set based on the component carrier types supported by the scheduling cell. The specific determination method is the same as the method for determining the component carrier types supported by the terminal 101 within the cell set in the above embodiment when the terminal capability information is used to indicate the component carrier types supported by the terminal in the scheduling cell, and will not be repeated here.

[0260] Exemplarily, the terminal capability information is used to indicate the component carrier types supported by the terminal in the scheduling cell and the scheduled cell. Assuming that the supported component carrier types are different, in specific circumstances, the component carrier types supported by the terminal 101 in the cell set can also be determined based on the component carrier types supported by the terminal 101 in the scheduled cell.

[0261] For example, when terminal 101 supports the first type of component carrier in the scheduling cell and supports the second type of component carrier in the scheduled cell, network device 102 can also determine the component carrier type supported by terminal 101 in the cell set based on the component carrier type supported by terminal 101 in the scheduled cell.

[0262] For another example, if terminal 101 supports the second type of component carrier in the scheduling cell and supports the first type of component carrier in the scheduled cell, terminal 101 is a high-capability terminal. For example, compared with a terminal with only basic data processing capabilities, terminal 101 has higher data processing capabilities. Network device 102 can also determine the component carrier type supported by terminal 101 in the cell set based on the component carrier type supported by terminal 101 in the scheduled cell.

[0263] The above description is merely an example, and the present disclosure is not limited to any specific situation.

[0264] Exemplarily, the terminal capability information is used to indicate 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. The network device 102 can determine whether the component carrier type supported by the terminal 101 in the cell set is: supporting the processing of a specified number of DCIs in each span, or supporting the processing of a specified number of DCIs in each slot.

[0265] The network device 102 may determine each span based on any span combination.

[0266] For example, the network device 102 may determine each span based on any one of the duration combinations (2, 2), (4, 3), and (7, 3).

[0267] Exemplarily, 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. Based on the aforementioned embodiment, 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, to determine the DCI processing capability supported by the terminal within the cell set.

[0268] Step S2103: The network device 102 sends DCI to the terminal 101 on the scheduling cell within the first time window.

[0269] In some embodiments, the DCI may perform multi-cell scheduling. Exemplarily, the DCI may include scheduling information of at least one cell in a cell set.

[0270] In some embodiments, the terminal 101 monitors the DCI sent by the network device 102 on the scheduling cell within the first time window.

[0271] In some embodiments, the number of DCIs monitored by the terminal 101 within the first time window is less than or equal to the above maximum number.

[0272] In some embodiments, network device 102 determines the DCI processing capability supported by terminal 101 within the cell set based on the terminal capability information. Then, based on the DCI processing capability supported by terminal 101 within the cell set, network device 102 sends DCI to terminal 101 on the scheduling cell within a first time window. Furthermore, the number of DCIs sent by network device 102 within the first time window is less than or equal to the maximum number.

For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, and steps S2101+S2102 may be implemented as independent embodiments, but are not limited thereto.

[0280] In some embodiments, step S2101 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 DCI processing capability supported by the terminal based on terminal capability information sent by other means or other entities, step S2101 may not be performed.

[0281] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the network device determines the DCI processing capability supported by the terminal based on a predefined method, step S2102 may not be performed.

[0282] In some embodiments, step S2103 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if the network device 102 does not perform multi-cell scheduling and only performs single-cell scheduling on the serving cell, step S2103 may not be performed.

[0283] In some embodiments, steps S2101 to S2103 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0284] In the above embodiment, the terminal can report terminal capability information to the network device, informing the network device of the DCI processing capabilities supported by the terminal when the cell set includes at least two types of component carriers. Based on the terminal capabilities, the network device can send DCI to the terminal on the scheduling cell within the first time window. This ensures that the network device and the terminal have a consistent understanding of the DCI processing capabilities supported by the terminal within the cell set, thereby improving the reliability and availability of multi-cell scheduling.

[0285] 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:

[0286] In step S2201 , the terminal 101 determines the DCI processing capability supported by the terminal 101 in the cell set based on a predefined method.

[0287] In some embodiments, a set of cells may be used for multi-cell scheduling.

[0288] Exemplarily, one or more cells in the cell set support being scheduled by the same DCI.

[0289] 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.

[0290] 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.

[0291] Exemplarily, the first type of component carrier may be a Release 16 component carrier.

[0292] Exemplarily, the first-category component carrier supports defining the DCI processing capability of the terminal based on the duration, including at least one of the following:

[0293] The capability of terminal 101 to process DCI within a span does not exceed the maximum capability of this type of terminal to process DCI as agreed upon in the protocol.

[0294] Exemplarily, a span includes one or more consecutive OFDM symbols belonging to the same time slot.

[0295] Exemplarily, the second-type component carrier may be a Release 15 component carrier.

[0296] Exemplarily, the second-category component carrier supports the definition of the DCI processing capability of the terminal based on the time slot, including at least one of the following:

[0297] The capability of the terminal 101 to process DCI in one slot does not exceed the maximum capability of this type of terminal to process DCI as agreed upon in the protocol.

[0298] 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.

[0299] In an example, the cell set includes only first-category component carriers, and the terminal 101 determines that the DCI processing capability supported in the cell set is defined based on a duration.

[0300] In an example, the cell set includes only the second type of component carriers, and the terminal 101 determines that the DCI processing capability supported in the cell set is defined based on a time slot.

[0301] In some embodiments, the terminal 101 determines the DCI processing capability supported by the terminal 101 in the cell set in the following predefined manner:

[0302] When the cell set includes at least two types of component carriers, determining the DCI processing capability supported by the terminal 101 in the cell set is based on a duration definition or a time slot definition;

[0303] When the cell set includes only the first type of component carriers, determining the DCI processing capability supported by the terminal 101 in the cell set is based on the duration definition;

[0304] When the cell set includes only the second type of component carriers, determining the DCI processing capability supported by the terminal 101 is based on the time slot definition.

[0305] In an example, when the cell set includes only the first type of component carrier, the capability of the terminal 101 to process DCI in each duration may be additionally defined in a predefined manner.

[0306] In step S2202 , the network device 102 determines the DCI processing capability supported by the terminal 101 in the cell set based on a predefined method.

[0307] 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 102 .

[0308] 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.

[0309] 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.

[0310] In an example, when the cell set configured by the network device 102 includes only the first type of component carriers, the network device 102 determines the DCI processing capability supported by the terminal 101 in the cell set based on the duration definition.

[0311] In an example, when the cell set configured by the network device 102 includes only the second type of component carriers, the network device 102 determines the DCI processing capability supported by the terminal 101 in the cell set based on a time slot definition.

[0312] In some embodiments, the network device 102 may determine the DCI processing capability supported by the terminal 101 within the cell set in the following manner:

[0313] When the cell set includes at least two types of component carriers, determining the DCI processing capability supported by the terminal 101 in the cell set is based on a duration definition or a time slot definition;

[0314] When the cell set includes only the first type of component carriers, determining the DCI processing capability supported by the terminal 101 in the cell set is based on the duration definition;

[0315] When the cell set includes only the second type of component carriers, determining the DCI processing capability supported by the terminal 101 in the cell set is based on the time slot definition.

[0316] In an example, when the cell set includes only the first type of component carrier, the DCI processing capability supported by the terminal 101 in each duration can be additionally defined in a predefined manner.

[0317] Step S2203: The network device 102 sends DCI to the terminal 101 on the scheduling cell within the first time window.

[0318] In some embodiments, the DCI may perform multi-cell scheduling. Exemplarily, the DCI may include scheduling information of at least one cell in a cell set.

[0319] In some embodiments, the terminal 101 monitors the DCI sent by the network device 102 on the scheduling cell within the first time window.

[0320] In some embodiments, the number of DCIs monitored by the terminal 101 within the first time window is less than or equal to the above maximum number.

[0321] In some embodiments, network device 102 determines the DCI processing capabilities supported by terminal 101 within the set of cells based on a predefined method. Then, based on the DCI processing capabilities supported by terminal 101 within the set of cells, network device 102 sends DCI to terminal 101 on the scheduling cell within a first time window. Furthermore, the number of DCIs sent by network device 102 within the first time window is less than or equal to the maximum number.

For example, step S3401 may be implemented as an independent embodiment, step S3402 may be implemented as an independent embodiment, and steps S3401+S3402 may be implemented as independent embodiments, but are not limited thereto.

[0394] In some embodiments, step S3401 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the terminal 101 needs to send terminal capability information, step S3401 may not be performed.

For example, if the network device 102 does not perform multi-cell scheduling and only performs single-cell scheduling on the serving cell, step S3402 may not be performed.

[0396] In some embodiments, steps S3401 to S3402 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0397] In the above embodiment, the network device can determine the DCI processing capability supported by the terminal in the cell set based on a predefined method, and then send DCI to the terminal in the scheduling cell within the first time window, ensuring that the network device and the terminal have a consistent understanding of the DCI processing capability supported by the terminal in the cell set, thereby improving the reliability and availability of multi-cell scheduling.

[0398] The above process is further illustrated by the following examples:

[0399] 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 DCI processing capability supported by the terminal in the cell set is determined based on the relevant capabilities reported by the terminal or a predefined method.

[0400] Terminal side:

[0401] When the cell set used for multi-cell scheduling contains both Release 15 component carriers and Release 16 component carriers, the terminal determines or indicates to the base station the number of DCIs that it can process in the following manner:

[0402] Method 1: The terminal reports to the network device that it is on a scheduling cell in a scheduling cell set and that it supports processing the maximum number of time units defined by the DCI. The terminal reports the terminal capability information to the network device. The terminal capability information includes at least:

[0403] The terminal reports the time granularity it supports.

[0404] For example, the time granularity is a span combination (X, Y) or N slots, where N is a positive integer.

[0405] The maximum number of DCIs that the terminal supports processing within the time unit is not limited

[0406] Method 2: Define terminal behavior. The terminal does not expect the following situations to occur:

[0407] The cell set includes both Rel-16 CC and Rel-15 CC.

[0408] That is, all terminals in the cell set only support Rel-15 CC or Rel-16 CC.

[0409] Method 3: The terminal determines its capability of processing DCI for the cell set according to a predefined method.

[0410] 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:

[0411] 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.

[0412] When the cell set contains only Rel-15 CC, it is processed as Rel-15 CC.

[0413] 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.

[0414] Among them, FG 11-related capabilities are terminal capabilities related to Ultra-Reliable Low-Latency Communications (URLLC), which refers to the ability to monitor and process PDCCHs on a per-span basis. In this case, per-span capabilities can be additionally defined.

[0415] Method 4: When reporting the scheduling cell and co-scheduled cell types, the terminal refines the reporting granularity of the scheduling cell type, adding a distinction between Rel-15 and Rel-16 types. Specifically, after reporting the scheduling cell and co-scheduled cell types (i.e., {FR1 licensed FDD, FR1 licensed TDD, FR1 unlicensed TDD, FR2-1, FR2-2}), the terminal additionally reports the co-scheduled cell as a Rel-15 CC or a Rel-16 CC.

[0416] Network device side:

[0417] When the cell set used for multi-carrier scheduling contains both Rel-15 CCs and Rel-16 CCs, the network device determines the MC terminal's ability to process DCI on the scheduling cell in the following manner, and ensures that the number of DCIs that the terminal needs to process within a specific time window on the scheduling cell does not exceed the terminal's capability limit.

[0418] Method 1: The network device receives corresponding capabilities reported by the terminal, where the terminal capabilities indicate a time unit defined by a maximum number of DCIs that the terminal can process on a scheduling cell in a cell set.

[0419] Method 2: The cell set configured by the network device for the terminal only contains Rel-15 CC or Rel-16 CC.

[0420] Method 3: The network device determines the maximum number of DCIs that the terminal can process within a specific time window on the scheduling cell of the scheduling cell set according to a predefined method.

[0421] Method 4: The network device receives the scheduling cell and co-scheduled cell types reported by the terminal to determine the maximum number of DCIs that the terminal can process within a specific time window of the scheduling cell.

[0422] The terminal capability notifies the base station that the supported scheduling cell is Rel-15 CC or Rel-16 CC; and / or,

[0423] The terminal capability notifies the base station that the co-scheduled cell supported by the terminal is Rel-15 CC or Rel-16 CC.

[0424] In Example 1, 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:

[0425] A maximum of 4 cell sets are supported in one PUCCH group;

[0426] In a cell set, up to 4 cells can be scheduled through one DCI.

[0427] 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:

[0428] Rel-15 CC means that the number of DCIs that the terminal can process on it is determined per slot;

[0429] Rel-16 CC means that the number of DCIs that a terminal can process on it is determined on a per span basis.

[0430] Span combination (X, Y) includes at least (2, 2), (4, 3), and (7, 3). X represents the number of OFDM symbols between the first OFDM symbols of two adjacent spans, and Y represents the number of consecutive OFDM symbols contained in each span.

[0431] In this embodiment, a time window is defined for the maximum number of DCIs that a terminal supports processing on a scheduling cell in a cell set. The terminal reports the terminal capabilities to the base station to indicate support for MC scheduling. When the cell set includes both Rel-15 CCs and Rel-16 CCs, the terminal's DCI processing capabilities on the scheduling cell are defined as per-span or per-slot DCI processing capabilities.

[0432] In this embodiment, it is assumed that the terminal capabilities include at least the following:

[0433] The terminal reports the time granularity it supports, which is a span combination (X, Y) or a slot.

[0434] 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:

[0435] The terminal reports its supported DCI processing capability time window. The time window is a span, a slot, or N consecutive slots. When the time window is a span, the terminal may report its DCI processing capability on the scheduling cell of the scheduling cell set. The span is determined to be (2, 2), (4, 3), or (7, 3).

[0436] Specifically, take the example of a terminal reporting its supported DCI processing capability time window as 1 slot. After the terminal reports this capability, it means that the maximum number of DCIs it can process is determined in units of slots. In this embodiment, there is no limit on the specific number of DCIs that the terminal can process within a slot. As just one possible implementation, its capability to process DCI within the slot can be defined as follows:

[0437] Process one downlink DCI and one uplink DCI on the FDD carrier;

[0438] One downlink DCI and two uplink DCIs are processed on the TDD carrier.

[0439] Of course, this patent does not exclude any other DCI processing capabilities.

[0440] In Example 2, 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:

[0441] A maximum of 4 cell sets are supported in one PUCCH group;

[0442] In a cell set, up to 4 cells can be scheduled through one DCI.

[0443] 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:

[0444] Rel-15 CC means that the number of DCIs that the terminal can process on it is determined per slot;

[0445] Rel-16 CC means that the number of DCIs that a terminal can process on it is determined on a per span basis.

[0446] Span combination (X, Y) includes at least (2, 2), (4, 3), and (7, 3). X represents the number of OFDM symbols between the first OFDM symbols of two adjacent spans, and Y represents the number of consecutive OFDM symbols contained in each span.

[0447] In this embodiment, the MC UE does not expect a cell set to contain both Rel-16 CCs and Rel-15 CCs. That is, when configuring a cell set for the terminal, the base station ensures that all CCs in the cell set are Rel-16 CCs or all Rel-15 CCs.

[0448] When all CCs in the cell set are Rel-15 CCs, the base station ensures that the number of DCIs that the MC UE needs to process in each slot of the scheduling cell corresponding to each scheduled cell in the cell set does not exceed a predetermined number. The maximum number of DCIs that the terminal can process varies according to the full-duplex mode of the scheduling cell or the scheduled cell.

[0449] When all CCs in the cell set are Rel-16 CCs, the base station ensures that the number of DCIs that the MC UE needs to process in each span of the scheduling cell corresponding to each scheduled cell in the cell set does not exceed a predetermined number. The maximum number of DCIs that the terminal can process varies according to the full-duplex mode of the scheduling cell or the scheduled cell.

[0450] 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:

[0451] A maximum of 4 cell sets are supported in one PUCCH group;

[0452] In a cell set, up to 4 cells can be scheduled through one DCI.

[0453] 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:

[0454] Rel-15 CC means that the number of DCIs that the terminal can process on it is determined per slot;

[0455] Rel-16 CC means that the number of DCIs that a terminal can process on it is determined on a per span basis.

[0456] Span combination (X, Y) includes at least (2, 2), (4, 3), and (7, 3). X represents the number of OFDM symbols between the first OFDM symbols of two adjacent spans, and Y represents the number of consecutive OFDM symbols contained in each span.

[0457] In this embodiment, the MC UE does not expect a cell set to contain both Rel-16 CCs and Rel-15 CCs. That is, when configuring a cell set for the terminal, the base station ensures that all CCs in the cell set are Rel-16 CCs or all Rel-15 CCs.

[0458] In this embodiment, the terminal determines its DCI processing capability for the cell set according to a predefined method. In this embodiment, there is no restriction on the cell types in the cell set, that is, the following cell combinations are supported:

[0459] The cell set includes both Rel-15 CC and Rel-16 CC;

[0460] Alternatively, the cell set only includes Rel-15 CC;

[0461] Alternatively, the cell set only includes Rel-16 CCs.

[0462] The Rel-15 CC and Rel-16 CC are determined based on the capabilities reported by the terminal. Correspondingly, the terminal and the network determine the relevant capabilities for processing DCI on the scheduling cell of the scheduling cell set according to the following predefined rules:

[0463] 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.

[0464] When the cell set contains only Rel-15 CC, it is processed according to Rel-15 CC;

[0465] 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.

[0466] At this time, you can additionally define the per span capability.

[0467] 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:

[0468] A maximum of 4 cell sets are supported in one PUCCH group;

[0469] In a cell set, up to 4 cells can be scheduled through one DCI.

[0470] 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:

[0471] Rel-15 CC means that the number of DCIs that the terminal can process on it is determined per slot;

[0472] Rel-16 CC means that the number of DCIs that a terminal can process on it is determined on a per span basis.

[0473] Span combination (X, Y) includes at least (2, 2), (4, 3), and (7, 3). X represents the number of OFDM symbols between the first OFDM symbols of two adjacent spans, and Y represents the number of consecutive OFDM symbols contained in each span.

[0474] 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. Based on the carrier type reported by the terminal, the base station determines the terminal's ability to process DCI on the scheduling cell that schedules the cell set, and uses this capability to configure a search space for the terminal on the scheduling cell.

[0475] Specifically, the terminal can report the carrier types it supports according to the following granularity:

[0476] Report the carrier type of the scheduling cell and scheduled cell separately. The specific carrier type includes at least one of the following:

[0477] Rel-15 FR1 licensed FDD

[0478] Rel-15 FR1 licensed TDD

[0479] Rel-16 FR1 licensed FDD
