According to the present disclosure, a terminal can determine the scheduling information in the legacy DCI by blindly detecting the DCI in the PDCCH in the embodiment of the present disclosure, and determine the scheduling information in the MC-DCI according to the first information scheduled by the DCI.

Description

[0001] This application is a divisional application of Chinese Patent Application No. 202280002277.0, filed on June 30, 2022, entitled "Method and Apparatus for Receiving and Sending Scheduling Information, Communication Device and Storage Medium". Technical Field

[0002] This disclosure relates to the field of communication technology, and more specifically, to a method for receiving scheduling information, a method for sending scheduling information, a device for receiving scheduling information, a device for sending scheduling information, a communication device, and a computer-readable storage medium. Background Technology

[0003] In related technologies, a single Downlink Control Information (DCI) is used to schedule data for only one cell, such as scheduling the Physical Uplink Shared Channel (PUSCH) and Physical Downlink Shared Channel (PDSCH) of a cell.

[0004] With the fragmentation of frequency resources, the demand for scheduling data from multiple cells simultaneously is gradually increasing. In order to reduce control message overhead, it is proposed to schedule data from multiple cells through a single DCI. For example, a DCI used to schedule data from multiple cells can be called MC-DCI, where MC stands for multi-cell or multi-carrier.

[0005] The DCI (Digital Channel Interface) is obtained by the terminal through blind detection of the Physical Downlink Control Channel (PDCCH). MC-DCI, as a newly introduced DCI, differs from the traditional (legacy) DCI. Obtaining both MC-DCI and legacy DCI through blind detection of the PDCCH increases the complexity of the blind detection process. Furthermore, if the MC-DCI contains information for scheduling multiple cells, its size increases, posing a significant challenge to the transmission performance of the PDCCH. Summary of the Invention

[0006] In view of the above, embodiments of this disclosure provide a scheduling information receiving method, a scheduling information sending method, a scheduling information receiving device, a scheduling information sending device, a communication device, and a computer-readable storage medium to solve the technical problems in the related art.

[0007] According to a first aspect of the present disclosure, a scheduling information receiving method is proposed, executed by a terminal, the method comprising: receiving legacy downlink control information (legacy DCI) sent by a network device, wherein the legacy DCI carries scheduling information, the scheduling information being used at least for scheduling first information, the first information carrying scheduling information for scheduling multiple cells.

[0008] According to a second aspect of the present disclosure, a scheduling information sending method is proposed, which is executed by a network device. The method includes sending legacy downlink control information (Legacy DCI) to a terminal, wherein the legacy DCI carries scheduling information, and the scheduling information is used at least for scheduling first information, the first information carrying scheduling information for scheduling multiple cells.

[0009] According to a third aspect of the present disclosure, a scheduling information receiving apparatus is provided, the apparatus comprising: a receiving module configured to receive legacy downlink control information (legacy DCI) sent by a network device, wherein the legacy DCI carries scheduling information, the scheduling information being used at least for scheduling first information, the first information carrying scheduling information for scheduling multiple cells.

[0010] According to a fourth aspect of the present disclosure, a scheduling information sending apparatus is provided, the apparatus comprising: a sending module configured to send legacy downlink control information (Legacy DCI) to a terminal, wherein the legacy DCI carries scheduling information, the scheduling information being used at least for scheduling first information, the first information carrying scheduling information for scheduling multiple cells.

[0011] According to a fifth aspect of the present disclosure, a communication device is provided, comprising: a processor; a memory for storing a computer program; wherein, when the computer program is executed by the processor, the above-described scheduling information receiving method is implemented.

[0012] According to a sixth aspect of the present disclosure, a communication device is provided, comprising: a processor; a memory for storing a computer program; wherein, when the computer program is executed by the processor, the above-described scheduling information transmission method is implemented.

[0013] According to a seventh aspect of the present disclosure, a computer-readable storage medium is provided for storing a computer program that, when executed by a processor, implements the steps in the scheduling information receiving method described above.

[0014] According to an eighth aspect of the present disclosure, a computer-readable storage medium is provided for storing a computer program that, when executed by a processor, implements the steps in the above-described scheduling information sending method.

[0015] According to embodiments of this disclosure, a terminal can receive a DCI sent by a network device. The network device can carry scheduling information for scheduling a single cell in the DCI. The scheduling information can be used to schedule first information, such as indicating the time domain resources and frequency domain resources of the first information. The first information can carry scheduling information for scheduling multiple cells.

[0016] The scheduling information used to schedule a single cell is equivalent to the scheduling information in legacy DCI, while the scheduling information used to schedule multiple cells is equivalent to the scheduling information in MC-DCI. That is, by blindly detecting the DCI in this embodiment of the present disclosure in the PDCCH, the terminal can determine the scheduling information in legacy DCI and the scheduling information in MC-DCI based on the first information scheduled by the DCI. Compared to blindly detecting legacy DCI and MC-DCI in the PDCCH, this reduces the types of DCIs that need to be obtained, thus reducing the complexity of blind detection.

[0029] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0030] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0031] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0032] For the sake of brevity and ease of understanding, this document uses the terms "greater than" or "less than", "higher than" or "lower than" to describe size relationships. However, it will be understood by those skilled in the art that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to"; the term "higher than" also includes the meaning of "higher than or equal to", and "lower than" also includes the meaning of "lower than or equal to".

[0033] As a newly introduced DCI, MC-DCI's format can differ from that of legacy DCI. Legacy DCI includes, but is not limited to, DCIs used for scheduling single cells, such as DCI format 0_0, DCI format 1_0, DCI format 0_1, DCI format 1_1, DCI format 0_2, and DCI format 1_2. MC-DCI, however, can use newly configured formats; for example, MC-DCI may include DCI format 0_3 and DCI format 1_3.

[0034] MC-DCI can be used to schedule multiple cells, while legacy DCI is used to schedule a single cell. Therefore, the functions of these two DCIs are different, and the meanings of the information fields in these two DCIs are also different. For example, in MC-DCI, one type of information field can indicate the scheduling information of multiple cells, while in legacy DCI, one type of information field can only indicate the scheduling information of one cell.

[0035] Based on this, the size (i.e., the number of bits) of MC-DCI and legacy DCI can differ. The more DCI sizes carried in the PDCCH, the higher the complexity for the terminal to obtain each DCI through blind detection of the PDCCH. For example, when there are 5 DCI sizes in the PDCCH, the complexity of blind detection of DCI by the terminal is relatively higher than when there are 4 DCI sizes in the PDCCH. This solution mainly addresses the technical problem of increased complexity in blind detection of PDCCH caused by the introduction of MC-DCI.

[0036] Figure 1 This is a schematic flowchart illustrating a scheduling information receiving method according to an embodiment of the present disclosure. The scheduling information receiving method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0037] like Figure 1 As shown, the scheduling information receiving method may include the following steps: In step S101, legacy downlink control information (legacy DCI) sent by the network device is received. The legacy DCI carries scheduling information, which is used at least for scheduling first information. The first information carries scheduling information for scheduling multiple cells.

[0038] It should be noted that in all embodiments of this disclosure, "scheduling cell" refers to the data transmission of the scheduling cell, including but not limited to the uplink transmission and downlink data transmission of the scheduling cell.

[0039] In one embodiment, a terminal may receive a legacy DCI sent by a network device. The network device may carry scheduling information in the legacy DCI. The scheduling information may be used to schedule first information, such as indicating the time domain resources and frequency domain resources of the first information. The first information may carry scheduling information for scheduling multiple cells.

[0040] The scheduling information used to schedule multiple cells is equivalent to the scheduling information in MC-DCI. That is, by blindly detecting the legacy DCI in this embodiment of the present disclosure in the PDCCH, the terminal can determine the scheduling information in the legacy DCI, and determine the scheduling information in MC-DCI based on the first information scheduled by the legacy DCI. Compared to blindly detecting both legacy DCI and MC-DCI in the PDCCH, this reduces the types of DCIs that need to be obtained, thus reducing the complexity of blind detection.

[0041] Although the terminal needs to determine the scheduling information for scheduling multiple cells carried in the first information, it first needs to determine the first information scheduled by the scheduling information in the legacy DCI. However, since the scheduling information in the legacy DCI can directly indicate the time-domain and frequency-domain resources, the terminal can directly determine the first information without blind detection. Therefore, the operational complexity is relatively lower than that of blind detection. Thus, the embodiments of this disclosure determine the first information based on the scheduling information, and then obtain the scheduling information for scheduling multiple cells from the first information. Compared to blindly detecting the MC-DCI from the PDCCH, the complexity is still relatively low. Moreover, since only the legacy DCI needs to be carried in the PDCCH, and the scheduling information for scheduling multiple cells is determined based on the information scheduled by the legacy DCI, the MC-DCI does not need to be carried in the PDCCH. This helps reduce the number of DCI sizes in the PDCCH and improves transmission performance.

[0042] It should be noted that the scheduling information used to schedule multiple cells is equivalent to the scheduling information in a single MC-DCI used to schedule multiple cells, and also equivalent to the scheduling information in multiple legacy DCIs used to schedule multiple cells. This disclosure emphasizes that the scheduling information used to schedule multiple cells is equivalent to the scheduling information in the MC-DCI, primarily to describe the difference from when the MC-DCI is carried in the PDCCH, and not to imply that the scheduling information for scheduling multiple cells is the same as the MC-DCI. That is, when the legacy DCI is carried in the PDCCH, the scheduling information for scheduling multiple cells can be determined based on the first information scheduled by the legacy DCI. The function of the scheduling information for scheduling multiple cells can be the same as that of the MC-DCI, but the form of the information can be different.

[0043] In one embodiment, the scheduling information carried by the legacy DCI is used to schedule at least one of the following cells: The cell where the legacy DCI is received; The cells that the legacy DCI can schedule (which can be determined according to the protocol or the network device instructions) include the cells corresponding to the preset cell identifiers; The cell indicated by the network device.

[0044] The cell scheduled by the scheduling information carried in the legacy DCI received by the terminal from the network device can be determined according to the protocol or according to the network instructions.

[0045] For example, if the protocol specifies that the cell is the cell where the terminal is located when receiving the legacy DCI, then the terminal can determine that the cell scheduled by the legacy DCI is the cell where it was located when receiving the legacy DCI. Furthermore, the terminal can receive first information in the cell where it was located when receiving the legacy DCI based on the legacy DCI (e.g., based on the time-domain resources and frequency-domain resources indicated by the legacy DCI), and obtain scheduling information for scheduling multiple cells from the first information.

[0046] For example, if the protocol stipulates that the cells scheduled by the legacy DCI include the cells corresponding to preset cell identifiers among the cells that the legacy DCI can schedule, then the terminal can determine that the cells scheduled by the legacy DCI are the cells corresponding to the preset cell identifiers among the cells that the DCI can schedule, such as the cell corresponding to the smallest cell identifier or the cell corresponding to the largest cell identifier. Furthermore, the terminal can receive first information in the cell corresponding to the preset cell identifier according to the legacy DCI (e.g., according to the time-domain resources and frequency-domain resources indicated by the legacy DCI), and obtain scheduling information for scheduling multiple cells from the first information.

[0047] For example, a network device sends an indication message to a terminal, indicating the cell to be scheduled by the scheduling information carried in the legacy DCI. The terminal can then determine the cell to be scheduled by the received legacy DCI based on the indication message sent by the network. Furthermore, the terminal can receive first information in the cell indicated by the network device according to the legacy DCI (e.g., according to the time-domain resources and frequency-domain resources indicated by the legacy DCI), and obtain scheduling information for scheduling multiple cells from the first information.

[0048] In one embodiment, the first information includes a Media Access Control Element (MAC CE).

[0049] The terminal can receive legacy DCI sent by the network device. The legacy DCI carries scheduling information, which can be used to schedule MAC CEs, for example, indicating the time domain resources and frequency domain resources of the MAC CEs. The MAC CEs can carry scheduling information for scheduling multiple cells.

[0050] Based on this, network devices only need to carry the legacy DCI in the PDCCH, and then determine the MAC CE based on the scheduling information in the legacy DCI. They can then obtain the scheduling information for scheduling multiple cells from the MAC CE. Thus, the MC-DCI does not need to be carried in the PDCCH. The terminal only needs to blindly detect the legacy DCI in the PDCCH, and then determine the MAC CE scheduled by the legacy DCI. In this way, it can obtain the scheduling information for scheduling multiple cells from the MAC CE, which is equivalent to the scheduling information in the MC-DCI.

[0051] It should be noted that the first information may include not only MAC CE, but also other information, such as DCI, that is, the scheduling information in legacy DCI can schedule DCI. The scheduled DCI carries scheduling information for scheduling multiple cells. The DCI scheduled by the scheduling information in legacy DCI can be located in PDCCH or carried in PDSCH in the form of data.

[0052] Figure 2 This is a schematic diagram illustrating an application of a scheduling information receiving method according to an embodiment of the present disclosure.

[0053] like Figure 2 As shown, taking three cells, Cell#0, Cell#1, and Cell#2, as an example, the network device can send a legacy DCI to the terminal from Cell#0. The MAC CE scheduled by the legacy DCI carries the scheduling information for scheduling Cell#1 and Cell#2.

[0054] After receiving the legacy DCI sent by the network device in Cell#0, the terminal can determine the MAC CE scheduled by the legacy DCI (e.g., the scheduled cell is Cell#0), and then receive the MAC CE in Cell#0. From the received MAC CE, the terminal can obtain the scheduling information for scheduling Cell#1 and Cell#2, such as the PDSCH for scheduling Cell#1 and Cell#2. Based on the scheduling information for scheduling Cell#1 and Cell#2, the terminal can receive the PDSCH in Cell#1 and Cell#2.

[0055] It should be noted that, since it takes a period of time *t* for the terminal to parse the MAC CE after successfully receiving it and determine the scheduling information used to schedule Cell#1 and Cell#2, the scheduling information in the MAC CE takes effect at least from the moment of successful MAC CE reception plus the duration *t*. For example, if the terminal determines that it has successfully received the MAC CE in time slot *n*, then the terminal can confirm the scheduling information for Cell#1 and Cell#2 after *t* + time slot *n*.

[0056] Figure 3 This is a schematic flowchart illustrating another scheduling information receiving method according to embodiments of the present disclosure. Figure 3 As shown, the scheduling information for scheduling multiple cells includes at least one type of information field, with one information field corresponding to the same type. The method further includes: In step S301, a first association relationship is determined between the value of the same type of information field in the scheduling information used to schedule multiple cells and the multiple scheduling information, and a second association relationship is determined between the multiple scheduling information and the multiple scheduled cells; In step S302, the scheduling information of each scheduled cell is determined based on the first association relationship and the second association relationship.

[0057] In one embodiment, the DCI may include various types of information fields, such as FDRA (Frequency Domain Resource Assignment) field, ZP CSI-RS trigger (Zero Power Channel Information Reference Signal trigger) field, and BandWidth Part indicator field.

[0058] For the existing DCI mechanism, one type of information domain can schedule a cell. For example, the FDRA information domain can schedule the frequency domain resources of the target cell.

[0059] This embodiment can be applied to scenarios where legacy DCI scheduling first information carries scheduling information for scheduling multiple cells.

[0060] In this embodiment, the network device can send a legacy DCI to the terminal. The legacy DCI carries scheduling information, which is used to schedule first information. The first information carries scheduling information for scheduling multiple cells. The scheduling information for scheduling multiple cells can schedule multiple cells (i.e., the cells to be scheduled). Specifically, the value of a specific information field (the value of one information field, not the values ​​of multiple information fields) in the scheduling information for scheduling multiple cells can be associated with multiple scheduling information (i.e., the value of one information field is associated with multiple scheduling information), for example, called the first association relationship. Furthermore, multiple scheduling information can be associated with multiple cells to be scheduled, for example, called the second association relationship. The multiple scheduling information types corresponding to the value of one type of information field are the same, for example, frequency domain resource (FDRA) corresponding to different cells, or BWP indexes configured for different cells.

[0061] This type of indication can be called a combined or shared indication. For example, a specific value indicated by a specific type of information field in a DCI can be associated with multiple scheduling information, which in turn are associated with multiple scheduled cells.

[0062] The first and second association relationships can be determined through predefined methods or through signaling indication. Taking signaling indication as an example, the network side can define a first association relationship between a specific value of a specific type information field in the scheduling information used to schedule multiple cells and multiple scheduling information, based on signaling indication (e.g., Radio Resource Control (RRC) signaling). The signaling can be the signaling configured in the cell where the legacy DCI is located. Taking RRC signaling as an example, the terminal receives the corresponding RRC signaling in the cell where the legacy DCI is located. The RRC signaling indicates the association relationship between a specific value of a specific type information field in the scheduling information used to schedule multiple cells and multiple scheduling information. The number of bits occupied by the specific type information field is related to the range of indication values ​​configured in the RRC signaling.

[0063] Taking the BWP indication field in the scheduling information used to schedule multiple cells as an example, in a DCI used to schedule 3 cells (cell IDs 0, 1 and 2 respectively), the corresponding DCI is received in cell 0.

[0064] For example, the first association is determined by signaling indication. The terminal receives the corresponding RRC signaling in cell 0 to determine the first association between the value of the BWP indication field in the scheduling information used to schedule multiple cells and the BWP ID configured in the multiple cells. For example, the first association for the BWP indication field can be shown in Table 1 below: Table 1 As shown in Table 1, the number of bits occupied by the BWP indicator field is log2(4)=2. In the scenario where the value of the BWP indicator field is 01, according to the first association relationship, it can be determined that the value of 01 in the BWP indicator field is associated with 3 scheduling information: the first scheduling information is BWPid=2, the second scheduling information is BWP id=3, and the third scheduling information is BWP id=1. Furthermore, according to the second association relationship, it can be determined that the first scheduling information is associated with cell 0, the second scheduling information is associated with cell 1, and the third scheduling information is associated with cell 2. Therefore, it can be determined that the BWP id of cell 0 is 2, the BWP id of cell 1 is 3, and the BWP id of cell 2 is 1.

[0065] For the information field of the characteristic type in the scheduling information used to schedule multiple cells, the value of the information field can be associated with the scheduling information. , … There are a total of n scheduling messages, where n equals the number of cells to be scheduled. For the community Scheduling information, For the community The scheduling information, and so on, For the community The scheduling information, among which This is the community ID number.

[0066] The terminal can determine a first association between the value of a specific information field in the scheduling information used to schedule multiple cells and the multiple scheduling information, and a second association between the multiple scheduling information and the multiple scheduled cells. Then, based on the first association, it can determine the multiple scheduling information corresponding to the value of the specific information field in the scheduling information used to schedule multiple cells, and based on the second association, determine the scheduled cell corresponding to each scheduling information, and further determine the scheduling information for each scheduled cell. Therefore, based on the network device scheduling multiple cells using the scheduling information used to schedule multiple cells, the terminal can accurately interpret the scheduling information for each cell indicated by the scheduling information used to schedule multiple cells. The above mainly describes the specific implementation of the first association; the determination of the corresponding second association will be discussed below.

[0067] It should be noted that the multiple cells scheduled in the scheduling information used to schedule multiple cells, i.e., the multiple scheduled cells, can be determined by the terminal based on the CIF (Cell Indicator Field) in the scheduling information used to schedule multiple cells, or by a pre-agreed agreement with the network device, or by a predefined rule (e.g., a protocol agreement). This disclosure does not limit this.

[0068] In one embodiment, determining the first association between the value of a specific information field in the scheduling information used to schedule multiple cells and the multiple scheduling information includes: determining the first association according to an instruction from the network device. For example, the network device can determine the association between the value of an information field (a single information field, rather than multiple information fields) in the DCI and the multiple scheduling information, and then instruct the terminal via RRC (Radio Resource Control) signaling. Alternatively, it can be determined according to predefined rules, such as based on protocol agreements.

[0069] In one embodiment, determining the second association between the plurality of scheduling information and the plurality of scheduled cells includes: determining the second association according to predefined rules.

[0070] The first association between the value of a specific information field in the scheduling information used to schedule multiple cells and the multiple scheduling information, and the second association between the multiple scheduling information and the multiple scheduled cells, can be defined by predefined rules, such as protocol agreements; or it can be indicated by network devices. The network devices can indicate the association in ways including, but not limited to, indicating via RRC signaling, DCI, or MAC CE. The number of bits occupied by the information fields in the scheduling information used to schedule multiple cells is determined by the number of values ​​based on signaling indication or a predetermined method. For example, if the first association defines the values ​​of N information fields, and the value of each information field is associated with multiple scheduling information, then the number of bits occupied by the information fields in the scheduling information used to schedule multiple cells is equal to log2(N).

[0071] The following examples are mainly illustrative of the case where the second association relationship is defined by a predefined rule.

[0072] In one embodiment, the scheduling information for scheduling multiple cells includes n scheduling information items, and the multiple scheduled cells include n scheduled cells; the predefined rule specifies that the j-th scheduling information item among the n scheduling information items is associated with the j-th scheduled cell among the n scheduled cells, where 1≤j≤n.

[0073] The scheduled cell may include the cell where the terminal received the legacy DCI and other cells (cells other than the one where the terminal received the legacy DCI among the scheduled cells), or it may exclude the cell where the terminal received the legacy DCI and only include other cells. In this implementation, the predefined rules, when specifying the association between the scheduled cell and the scheduling information, may not distinguish between the cell where the terminal received the legacy DCI and other cells, and may specify the association between the cell where the terminal received the legacy DCI and other cells and the scheduling information according to the same rules.

[0074] Taking n scheduled cells as an example, n scheduling information can be determined based on the first association relationship and the value of the information field in the scheduling information of multiple cells. The correspondence between the n scheduling information and the n scheduled cells can be determined based on the second association relationship. The second association relationship can be that the j-th scheduling information among the n scheduling information is associated with the j-th scheduled cell among the n scheduled cells.

[0075] Accordingly, the terminal can determine that the j-th scheduling information is the scheduling information of the j-th scheduled cell. Thus, based on the network device scheduling multiple cells by scheduling multiple cells, the terminal can accurately interpret the scheduling information of each cell indicated by the scheduling information of multiple cells.

[0076] For example, considering the n scheduled cells from the 1st cell to the nth cell, taking the FDRA field using the combine indication method as an example, n scheduling information can be determined based on the value of the FDRA field and the first association relationship, for example... to ,in This refers to the cell ID. In this embodiment, the terminal can determine the first scheduling information as the first scheduled cell (cell ID) based on the second association relationship. The frequency domain scheduling information of the first cell and the second scheduling information of the second cell are the frequency domain scheduling information of the second cell. The frequency domain scheduling information of the j-th cell, ..., the j-th scheduling information is the j-th scheduled cell (cell) The frequency domain scheduling information of the nth cell, ..., the nth scheduling information is the nth scheduled cell (cell) The frequency domain scheduling information of multiple cells is used to schedule multiple cells, thereby enabling the terminal to accurately interpret the frequency domain scheduling information of each cell indicated by the scheduling information of multiple cells.

[0077] For example, considering the n scheduled cells from the 1st cell to the nth cell, taking the ZP CSI-RS trigger field using the combine indication method as an example, n scheduling information can be determined based on the value of the ZP CSI-RS trigger field and the first association relationship. to ,in This refers to the cell ID. In this embodiment, the terminal can determine the first scheduling information as the first scheduled cell (cell ID) based on the second association relationship. The ZP CSI-RS trigger information and the second scheduling information are for the second scheduled cell (cell). The ZP CSI-RS trigger information, ..., the j-th scheduling information is the j-th scheduled cell (cell) The ZP CSI-RS trigger information, ..., the nth scheduling information is the nth scheduled cell (cell) The ZP CSI-RS trigger information is obtained by scheduling multiple cells through scheduling information of multiple cells, thereby enabling the terminal to accurately interpret the ZP CSI-RS trigger information of each cell indicated by the scheduling information of multiple cells.

[0078] For example, considering the n scheduled cells from the 1st cell to the nth cell, taking the BWP indication field using the combine indication method as an example, n scheduling information can be determined based on the value of the BWP indication field and the first association relationship, for example... to ,in This refers to the cell ID. In this embodiment, the terminal can determine the first scheduling information as the first scheduled cell (cell ID) based on the second association relationship. The BWP information and the second scheduling information are for the second scheduled cell (cell). The BWP information of the j-th cell, ..., the j-th scheduling information is the j-th scheduled cell (cell) The BWP information of the nth BWP, ..., the scheduling information of the nth BWP is the scheduling information of the nth cell (cell). The BWP information of the multiple cells is used to schedule multiple cells, thereby enabling the terminal to accurately interpret the BWP information of each cell indicated by the scheduling information of multiple cells.

[0079] The order of the multiple scheduled cells will be explained in subsequent embodiments.

[0080] The following examples illustrate how a predefined rule, in accordance with the same rule, defines the association between the cell where the terminal receives the legacy DCI and other cells and the information domain, and how to determine the order of multiple scheduled cells.

[0081] In one embodiment, the predefined rule stipulates that the identifier of the j-th scheduled cell is less than the identifier of the (j+1)-th scheduled cell, for example... Less than Alternatively, the predefined rule stipulates that the identifier of the j-th scheduled cell is greater than the identifier of the (j+1)-th scheduled cell, for example... Greater than .

[0082] In one implementation, the identifier of the scheduled cell (e.g., Cell ID) can be determined by the terminal based on the RRC signaling sent by the network device, for example, based on information elements (IEs) such as ServcellIndex and / or SCellIndex in the RRC signaling. If the cell identifier corresponds to PCI (Physical Cell Identity), it can be determined based on the PhysCellId information element in the RRC signaling. Of course, it can also be determined based on other signaling. Alternatively, it can be determined in other ways, such as by predefined rules.

[0083] Predefined rules can specify the sorting of scheduled cells based on their identifiers. For example, they can be sorted from smallest to largest identifier, in which case the identifier of the j-th scheduled cell is less than the identifier of the (j+1)-th scheduled cell, or they can be sorted from largest to smallest identifier, in which case the identifier of the j-th scheduled cell is greater than the identifier of the (j+1)-th scheduled cell.

[0084] For example, consider four cells being scheduled: cell #1 (identified as 1), cell #2 (identified as 2), cell #3 (identified as 3), and cell #4 (identified as 4). If sorted by identifier from smallest to largest, then... Less than We can determine that the first cell is cell #1, the second cell to be scheduled is cell #2, the third cell is cell #3, and the fourth cell is cell #4; if sorted by identifier from largest to smallest, then... Greater than We can determine that the first cell is cell #4, the second cell to be dispatched is cell #3, the third cell is cell #2, and the fourth cell is cell #1.

[0085] Based on this, the cell order can be accurately determined according to the cell identifier, and then the j-th information field can be determined to be the scheduling information of the j-th scheduled cell.

[0086] Figure 4 This is a schematic flowchart illustrating another scheduling information receiving method according to embodiments of the present disclosure. Figure 4 As shown, the scheduling information for scheduling multiple cells includes at least one type of information field, with multiple information fields corresponding to the same type. The method further includes: In step S401, the association between multiple information fields of the same type in the scheduling information used to schedule multiple cells and multiple scheduled cells is determined; In step S402, the scheduling information of each scheduled cell is determined based on the value of each information field and the association relationship.

[0087] For the existing DCI mechanism, there is generally only one information domain of the same type. A cell can be scheduled based on this type of information domain. For example, the FDRA information domain can schedule the frequency domain resources of the target cell.

[0088] This embodiment can be applied to scenarios where legacy DCI scheduling first information carries scheduling information for scheduling multiple cells.

[0089] In this embodiment, the network device can send a legacy DCI to the terminal. The legacy DCI carries scheduling information, which is used to schedule first information. The first information carries scheduling information for scheduling multiple cells. The scheduling information for scheduling multiple cells can schedule multiple cells (i.e., the cells to be scheduled). One possible design is as follows: For one or more types of information fields in the scheduling information for scheduling multiple cells, for multiple cells to be scheduled, multiple information fields of the same type can be set in the scheduling information for scheduling multiple cells. Each information field can be scheduled for one cell. Information fields of the same type correspond to the same information type, for example, indicating the frequency domain resource (FDRA) of different cells, or indicating the BWP index configured for different cells.

[0090] This indication method can be called the separate method. For example, a specific type of information field in the scheduling information used to schedule multiple cells can include multiple information fields. Based on the information field for scheduling a single cell, the specific type of information field can be expanded by corresponding bits according to the number of cells being scheduled, thus obtaining multiple information fields of the same type, where different information fields indicate messages for different cells. The number of bits occupied by multiple information fields of the same type is equal to the sum of the number of bits occupied by the aforementioned information fields for each scheduled cell (of course, it can be set to equal other numbers as needed). The number of bits occupied by the aforementioned information fields for each scheduled cell can be the same as the number of bits occupied by the same type of information field in the DCI for scheduling a cell in the existing mechanism, or it can be the same as the maximum number of bits occupied by the same type of information field in the DCI for scheduling a cell in the existing mechanism.

[0091] Figure 5 This is a schematic flowchart illustrating a scheduling information transmission method according to an embodiment of the present disclosure. The scheduling information transmission method shown in this embodiment can be executed by a network device that can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0092] like Figure 5 As shown, the scheduling information sending method may include the following steps: In step S501, legacy downlink control information (legacy DCI) is sent to the terminal. The legacy DCI carries scheduling information, which is used at least for scheduling first information. The first information carries scheduling information for scheduling multiple cells.

[0093] In one embodiment, a network device may send a legacy DCI to a terminal. The legacy DCI may carry scheduling information, which may be used to schedule first information, such as indicating the time-domain and frequency-domain resources of the first information. The first information may also carry scheduling information for scheduling multiple cells.

[0094] The scheduling information used to schedule a single cell is equivalent to the scheduling information in legacy DCI, while the scheduling information used to schedule multiple cells is equivalent to the scheduling information in MC-DCI. That is, by blindly detecting the legacy DCI in this embodiment of the present disclosure in the PDCCH, the terminal can determine the scheduling information in the legacy DCI and, based on the first information scheduled by the legacy DCI, determine the scheduling information in the MC-DCI. Compared to blindly detecting both legacy DCI and MC-DCI in the PDCCH, this reduces the types of DCIs that need to be obtained, thus reducing the complexity of blind detection.

[0095] Although the terminal needs to determine the scheduling information for scheduling multiple cells carried in the first information, it first needs to determine the first information scheduled by the scheduling information in the legacy DCI. However, since the scheduling information in the legacy DCI can directly indicate the time-domain and frequency-domain resources, the terminal can directly determine the first information without blind detection. Therefore, the operational complexity is relatively lower than that of blind detection. Thus, the embodiments of this disclosure determine the first information based on the scheduling information, and then obtain the scheduling information for scheduling multiple cells from the first information. Compared to blindly detecting the MC-DCI from the PDCCH, the complexity is still relatively low. Moreover, since only the legacy DCI needs to be carried in the PDCCH, and the scheduling information for scheduling multiple cells is determined based on the information scheduled by the legacy DCI, the MC-DCI does not need to be carried in the PDCCH. This helps reduce the number of DCI sizes in the PDCCH and improves transmission performance.

[0096] It should be noted that the scheduling information used to schedule multiple cells is equivalent to the scheduling information in MC-DCI, and also equivalent to the scheduling information in multiple legacy DCIs used to schedule multiple cells. This disclosure emphasizes that the scheduling information used to schedule multiple cells is equivalent to the scheduling information in MC-DCI, mainly to describe the difference from when MC-DCI is carried in the PDCCH, not to imply that the scheduling information for scheduling multiple cells is MC-DCI. That is, when legacy DCI is carried in the PDCCH, the scheduling information for scheduling multiple cells can be determined based on the first information scheduled by the legacy DCI. The function of the scheduling information for scheduling multiple cells can be the same as that of MC-DCI, but the form of the information can be different.

[0097] In one embodiment, the scheduling information carried by the legacy DCI is used to schedule at least one of the following cells: The cell used to transmit the legacy DCI; The cells that the legacy DCI can schedule correspond to the preset cell identifiers; The cell indicated by the network device.

[0098] The scheduling information carried in the legacy DCI sent by the network device to the terminal refers to a cell that can be scheduled according to the protocol or determined autonomously by the network, and then the terminal is informed of the scheduling information through the instruction information.

[0099] For example, if the protocol specifies that the cell is the cell used by the network device to send the legacy DCI, then the network device can determine that the cell scheduled to send the legacy DCI to the terminal is the cell used to send the legacy DCI. Furthermore, the network device can send first information to the terminal from the cell used to send the legacy DCI, carrying scheduling information for scheduling multiple cells in the first information.

[0100] For example, if the protocol stipulates that the cells scheduled by the legacy DCI include the cells corresponding to preset cell identifiers among the cells that the legacy DCI can schedule, then the network can determine that the cells scheduled by the legacy DCI sent to the terminal are the cells corresponding to the preset cell identifiers among the cells that the legacy DCI can schedule, such as the cell corresponding to the smallest cell identifier or the cell corresponding to the largest cell identifier. Furthermore, the network device can send first information to the terminal from the cell corresponding to the preset cell identifier, carrying scheduling information for scheduling multiple cells in the first information.

[0101] For example, a network device can autonomously determine the cells scheduled by the legacy DCI sent to the terminal as needed, and then indicate the cells scheduled by the scheduling information carried in the legacy DCI by sending indication information to the terminal. Furthermore, the network device can send first information to the terminal in the indicated cell, carrying scheduling information for scheduling multiple cells.

[0102] In one embodiment, the first information includes a Media Access Control Layer Control Unit (MAC CE).

[0103] Network devices can send legacy DCIs to terminals, which carry scheduling information for scheduling a single cell. The scheduling information can be used to schedule MAC CEs, for example, indicating the time-domain and frequency-domain resources of the MAC CEs. The MAC CEs can carry scheduling information for scheduling multiple cells.

[0104] Based on this, network devices only need to carry the legacy DCI in the PDCCH, and then determine the MAC CE based on the scheduling information in the legacy DCI. They can then obtain the scheduling information for scheduling multiple cells from the MAC CE. Thus, the MC-DCI does not need to be carried in the PDCCH. The terminal only needs to blindly detect the legacy DCI in the PDCCH, and then determine the MAC CE scheduled by the legacy DCI. In this way, it can obtain the scheduling information for scheduling multiple cells from the MAC CE, which is equivalent to the scheduling information in the MC-DCI.

[0105] It should be noted that the first information may include not only MAC CE, but also other information, such as DCI, that is, the scheduling information in legacy DCI can schedule DCI, and the scheduled DCI can be carried in PDSCH, but does not have to be carried in PDCCH.

[0106] Figure 6 This is a schematic flowchart illustrating another scheduling information sending method according to embodiments of the present disclosure. Figure 6 As shown, the scheduling information for scheduling multiple cells includes at least one type of information field, with one information field corresponding to the same type. The method further includes: In step S601, a first association relationship is determined between the value of the same type of information field in the scheduling information used to schedule multiple cells and the multiple scheduling information of the same type, and a second association relationship is determined between the multiple scheduling information and the multiple scheduled cells; In step S602, the first information is generated based on the first association relationship and the second association relationship.

[0107] In one embodiment, the DCI may include multiple types of information fields, such as FDRA field, ZP CSI-RStrigger field, partial bandwidth indication field, etc.

[0108] For the existing DCI mechanism, one type of information domain can schedule a cell. For example, the FDRA information domain can schedule the frequency domain resources of the target cell.

[0109] This embodiment can be applied to scenarios where legacy DCI scheduling first information carries scheduling information for scheduling multiple cells.

[0110] In this embodiment, the network device can send a legacy DCI to the terminal. The legacy DCI carries scheduling information, which is used to schedule first information. The first information carries scheduling information for scheduling multiple cells. The scheduling information for scheduling multiple cells can schedule multiple cells (i.e., the cells to be scheduled). Specifically, the value of a specific information field (the value of one information field, not the values ​​of multiple information fields) in the scheduling information for scheduling multiple cells can be associated with multiple scheduling information (i.e., the value of one information field is associated with multiple scheduling information), for example, called the first association relationship. Furthermore, multiple scheduling information can be associated with multiple cells to be scheduled, for example, called the second association relationship. The multiple scheduling information types corresponding to the value of one type of information field are the same, for example, frequency domain resource (FDRA) corresponding to different cells, or BWP indexes configured for different cells.

[0111] This indication method can be called a combined or shared indication. For example, a specific value indicated by a specific type of information field in a DCI can be associated with multiple scheduling information, which in turn are associated with multiple scheduled cells.

[0112] The first and second association relationships can be determined through predefined methods or through signaling indication. Taking signaling indication as an example, the network side can define a first association relationship between a specific value of a specific type information field in the scheduling information used to schedule multiple cells and multiple scheduling information, based on signaling indication (e.g., Radio Resource Control (RRC) signaling). The signaling can be the signaling configured in the cell where the legacy DCI is located. Taking RRC signaling as an example, the terminal receives the corresponding RRC signaling in the cell where the legacy DCI is located. The RRC signaling indicates the association relationship between a specific value of a specific type information field in the scheduling information used to schedule multiple cells and multiple scheduling information. The number of bits occupied by the specific type information field is related to the range of indication values ​​configured in the RRC signaling.

[0113] Figure 7 This is a schematic flowchart illustrating another scheduling information sending method according to embodiments of the present disclosure. Figure 7 As shown, the scheduling information for scheduling multiple cells includes at least one type of information field, with multiple information fields corresponding to the same type. The method further includes: In step S701, the association between multiple information fields of the same type in the scheduling information used to schedule multiple cells and multiple scheduled cells is determined; In step S702, the first information is generated based on the association relationship.

[0114] In one embodiment, the DCI may include multiple types of information fields, such as FDRA field, ZP CSI-RStrigger field, partial bandwidth indication field, etc.

[0115] In existing DCIs, there is generally only one information field of the same type. A cell can be scheduled based on this type of information field. For example, the FDRA information field can schedule the frequency domain resources of the cell.

[0116] This embodiment can be applied to scenarios where legacy DCI scheduling first information carries scheduling information for scheduling multiple cells.

[0117] In this embodiment, the network device can determine the association between multiple information fields of the same type and multiple scheduled cells, and then set the information field of each cell according to the association, thereby generating scheduling information for scheduling multiple cells, and sending the scheduling information for scheduling multiple cells to the terminal to realize the scheduling of multiple cells. Information fields of the same type correspond to the same type of information, for example, indicating the frequency domain resource (FDRA) of different cells, or indicating the BWP index configured for different cells.

[0118] This indication method can be called separate indication. For example, a specific type of information field in the scheduling information used to schedule multiple cells can include multiple information fields. Based on the information field for scheduling a single cell, the specific type of information field can be expanded by corresponding bits according to the number of cells being scheduled, thus obtaining multiple information fields of the same type, where different information fields indicate messages for different cells. The number of bits occupied by multiple information fields of the same type is equal to the sum of the number of bits occupied by the aforementioned information fields for each scheduled cell (of course, it can be set to equal other numbers as needed). The number of bits occupied by the aforementioned information fields for each scheduled cell is the same as the number of bits occupied by the same type of information field for scheduling a single cell's DCI in the existing mechanism.
