Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of communication, and in particular, to a scheduling information receiving method, a scheduling information sending method, a scheduling information receiving apparatus, a scheduling information sending apparatus, a communication apparatus, and a computer readable storage medium. BACKGROUND

[0002] In the related art, one downlink control information (DCI) is used to schedule data of one cell, for example, to schedule a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH) of one cell.

[0003] With the fragmentation of frequency resources, the demand for scheduling data of multiple cells simultaneously gradually increases. In order to reduce the control message overhead, it is proposed to schedule data of multiple cells by a single DCI, for example, a DCI used to schedule multiple cells (data), which can be referred to as MC-DCI, where MC represents multi-cell or multi-carrier.

[0004] The DCI is obtained by the terminal through blind detection of a physical downlink control channel (PDCCH). The MC-DCI, as a newly introduced DCI, is different from the legacy DCI. In order to obtain the MC-DCI and the legacy DCI through blind detection of the PDCCH, the complexity of blind detection will be increased. At the same time, if the MC-DCI contains information for scheduling multiple cells, the size of the MC-DCI will be increased, which brings great challenges to the transmission performance of the PDCCH. SUMMARY

[0005] Therefore, embodiments of the present disclosure provide a scheduling information receiving method, a scheduling information sending method, a scheduling information receiving apparatus, a scheduling information sending apparatus, a communication apparatus, and a computer readable storage medium to solve the technical problems in the related art.

[0006] According to a first aspect of embodiments of the present disclosure, a scheduling information receiving method is provided, which is performed by a terminal, and the method comprises: receiving a legacy downlink control information (DCI) sent by a network device, wherein the legacy DCI carries scheduling information, and the scheduling information is used at least for scheduling first information, and the first information carries scheduling information used for scheduling multiple cells.

[0007] According to a second aspect of embodiments of the present disclosure, a method for sending scheduling information is provided. The method is performed by a network device, and includes sending, by the network device, a legacy DCI to the network device, wherein the legacy DCI carries scheduling information, and the scheduling information is used for scheduling at least first information, and the first information carries scheduling information used for scheduling multiple cells.

[0008] According to a third aspect of embodiments of the present disclosure, a receiving apparatus for scheduling information is provided. The apparatus includes a receiving module configured to receive a legacy DCI sent by a network device, wherein the legacy DCI carries scheduling information, and the scheduling information is used for scheduling at least first information, and the first information carries scheduling information used for scheduling multiple cells.

[0009] According to a fourth aspect of embodiments of the present disclosure, a sending apparatus for scheduling information is provided. The apparatus includes a sending module configured to send, by the network device, a legacy DCI to the network device, wherein the legacy DCI carries scheduling information, and the scheduling information is used for scheduling at least first information, and the first information carries scheduling information used for scheduling multiple cells.

[0010] According to a fifth aspect of embodiments of the present disclosure, a communication apparatus is provided. The apparatus includes a processor, and a memory for storing a computer program. When the computer program is executed by the processor, the above-mentioned method for receiving scheduling information is implemented.

[0011] According to a sixth aspect of embodiments of the present disclosure, a communication apparatus is provided. The apparatus includes a processor, and a memory for storing a computer program. When the computer program is executed by the processor, the above-mentioned method for sending scheduling information is implemented.

[0012] According to a seventh aspect of embodiments of the present disclosure, a computer readable storage medium is provided for storing a computer program, and when the computer program is executed by a processor, the steps of the above-mentioned method for receiving scheduling information are implemented.

[0013] According to an eighth aspect of embodiments of the present disclosure, a computer readable storage medium is provided for storing a computer program, and when the computer program is executed by a processor, the steps of the above-mentioned method for sending scheduling information are implemented.

[0014] According to an embodiment of the present disclosure, a terminal can receive DCI sent by a network device, wherein the network device can carry scheduling information for scheduling a single cell in the DCI, wherein the first information can be scheduled by the scheduling information, for example, time domain resources and frequency domain resources indicating the first information, and the scheduling information for scheduling multiple cells can be carried in the first information.

[0015] The scheduling information for scheduling a single cell is equivalent to the scheduling information in the legacy DCI, and the scheduling information for scheduling multiple cells is equivalent to the scheduling information in the MC-DCI. That is, the 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. Compared with the case of blindly detecting the legacy DCI and the MC-DCI in the PDCCH, the type of DCI to be obtained is reduced, which is conducive to reducing the blind detection complexity.

[0028] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present disclosure.

[0029] The terms used in the embodiments of the present disclosure are merely for the purpose of describing particular embodiments and are not intended to limit the embodiments of the present disclosure. The singular forms "a", "an" and "the" used in the embodiments of the present disclosure and the appended claims are intended to include plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0030] It should be understood that although the terms first, second, third, etc. can be used in the embodiments of the present disclosure to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another type of information. For example, without departing from the scope of the embodiments of the present disclosure, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information. Depending on the context, the word "if" as used herein can be interpreted as "when" or "upon" or "in response to determining".

[0031] For the purpose of brevity and ease of understanding, the terms "greater than" or "less than", "higher than" or "lower than" are used herein when characterizing size relationships. However, it will be understood by those skilled in the art that the term "greater than" also encompasses the meaning of "greater than or equal to", and the term "less than" also encompasses the meaning of "less than or equal to"; the term "higher than" encompasses the meaning of "higher than or equal to", and the term "lower than" encompasses the meaning of "lower than or equal to".

[0032] As a newly introduced DCI, the format of MC-DCI can be different from the format of legacy DCI, including but not limited to DCI for scheduling a single cell, such as DCI format 0_0, DCI format 1_0, DCI format 0_1, DCI format 1_1, DCI format 0_2, DCI format 1_2. While the format of MC-DCI can be a newly configured format, such as DCI format 0_3, DCI format 1_3.

[0033] MC-DCI can be used to schedule multiple cells, while legacy DCI is used to schedule a single cell, so the functions of the two types of DCI are different, and the meanings of the information fields in the two types of DCI are also different. For example, a type of information field in MC-DCI can indicate scheduling information for multiple cells, while a type of information field in legacy DCI can only indicate scheduling information for one cell.

[0034] On this basis, the size (i.e., the number of bits occupied) of MC-DCI and legacy DCI can be different, and the more sizes of DCI carried in PDCCH, the higher the complexity of the terminal in blind detection of PDCCH to obtain each type of DCI. For example, when there are 5 sizes of DCI in PDCCH, the complexity of the terminal in blind detection of DCI is relatively high compared to when there are 4 sizes of DCI in PDCCH. The present solution is mainly aimed at the technical problem of increasing the complexity of blind detection of PDCCH caused by the introduction of MC-DCI.

[0035] Figure 1 is a schematic flowchart of a scheduling information receiving method according to an embodiment of the present disclosure. The scheduling information receiving method shown in the present embodiment can be executed by a terminal, including but not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, and the like. The terminal can communicate with a network device, including but not limited to a network device in a 4G, 5G, 6G, or the like communication system, such as a base station, a core network, and the like.

[0036] As Figure 1 indicated, the scheduling information receiving method can include the following steps:

[0037] In step S101, a legacy DCI transmitted by a network device is received, wherein the legacy DCI carries scheduling information, and the scheduling information is used at least for scheduling first information, and the first information carries scheduling information used for scheduling multiple cells.

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

[0039] In one embodiment, a terminal can receive a legacy DCI transmitted by a network device, and the network device can carry scheduling information in the legacy DCI, wherein the scheduling information can be used to schedule first information, for example, to indicate time domain resources and frequency domain resources of the first information, and the first information can carry scheduling information used for scheduling multiple cells.

[0040] The scheduling information used for scheduling multiple cells is equivalent to the scheduling information in the MC-DCI. That is, the terminal can determine the scheduling information in the legacy DCI by blind detection of the legacy DCI in the PDCCH, and determine the scheduling information in the MC-DCI according to the first information scheduled by the legacy DCI. Compared with the case of blind detection of the legacy DCI and the MC-DCI in the PDCCH, the type of DCI to be obtained is reduced, which is conducive to reducing the blind detection complexity.

[0041] Although the terminal needs to determine the first information scheduled by the scheduling information in the legacy DCI in order to determine the scheduling information used for scheduling multiple cells carried in the first information, since the scheduling information in the legacy DCI can directly indicate the time domain resources and the frequency domain resources, the terminal can directly determine the first information without blind detection, so the operation complexity of blind detection is relatively low. Therefore, the embodiment of the present disclosure determines the first information according to the scheduling information, and then obtains the scheduling information used for scheduling multiple cells from the first information. Compared with blind detection of the MC-DCI in the PDCCH, the complexity is relatively low. Moreover, since only the legacy DCI needs to be carried in the PDCCH, the scheduling information used for scheduling multiple cells is determined according to the information scheduled by the legacy DCI, so the MC-DCI does not need to be carried in the PDCCH, which is conducive to reducing the number of DCI sizes in the PDCCH and improving the transmission performance.

[0042] It should be noted that the scheduling information for scheduling multiple cells is equivalent to the scheduling information in the MC-DCI for scheduling multiple cells, and is also equivalent to the scheduling information in multiple legacy DCIs for scheduling multiple cells. In the embodiments of the present disclosure, the scheduling information for scheduling multiple cells is equivalent to the scheduling information in the MC-DCI, mainly to distinguish when the MC-DCI is carried in the PDCCH, and not to mean that the scheduling information for scheduling multiple cells is the MC-DCI, that is, the legacy DCI is carried in the PDCCH, and the first information scheduled according to the legacy DCI can determine the scheduling information for scheduling multiple cells. 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:

[0044] The cell in which the legacy DCI is received;

[0045] The preset cell corresponding to the cell identified by the legacy DCI (which can be determined according to the protocol agreement, or can be determined according to the network device indication) can be scheduled by the legacy DCI.

[0046] The cell indicated by the network device.

[0047] 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 agreement or the network indication.

[0048] For example, the protocol agreement specifies that the cell is the cell in which the terminal receives the legacy DCI, so the terminal can determine that the cell scheduled by the legacy DCI is the cell in which the legacy DCI is received. Further, the terminal can receive the first information according to the legacy DCI (for example, according to the time domain resource and frequency domain resource indicated by the legacy DCI) in the cell in which the legacy DCI is received, and obtain the scheduling information for scheduling multiple cells from the first information.

[0049] For example, the cell scheduled by the legacy DCI includes a cell corresponding to a preset cell identifier in the cells that can be scheduled by the legacy DCI, and the terminal can determine that the cell scheduled by the legacy DCI is a cell corresponding to a preset cell identifier, for example, a cell corresponding to the smallest cell identifier or a cell corresponding to the largest cell identifier, in the cells that can be scheduled by the DCI. Then, the terminal can receive first information according to the legacy DCI (for example, according to the time domain resource and the frequency domain resource indicated by the legacy DCI) in the cell corresponding to the preset cell identifier, and obtain scheduling information for scheduling multiple cells from the first information.

[0050] For example, the network device indicates the cell scheduled by the scheduling information carried in the legacy DCI by sending indication information to the terminal, and then the terminal can determine the cell scheduled by the scheduling information in the received legacy DCI according to the indication information sent by the network. Then, the terminal can receive first information according to the legacy DCI (for example, according to the time domain resource and the frequency domain resource indicated by the legacy DCI) in the cell indicated by the network device, and obtain scheduling information for scheduling multiple cells from the first information.

[0051] In one embodiment, the first information includes a media access control layer control element (MAC CE).

[0052] The terminal can receive the legacy DCI sent by the network device, and the legacy DCI carries scheduling information. Through the scheduling information, a MAC CE can be scheduled, for example, time domain resource and frequency domain resource of the MAC CE are indicated, and the MAC CE can carry scheduling information for scheduling multiple cells.

[0053] On this basis, the network device only needs to carry the legacy DCI in the PDCCH, and then determines the MAC CE according to the scheduling information in the legacy DCI, and obtains the scheduling information for scheduling multiple cells from the MAC CE, so that the PDCCH does not need to carry the MC-DCI. The terminal only needs to perform blind detection on the legacy DCI in the PDCCH, and then determines the MAC CE scheduled by the legacy DCI, and then can obtain the scheduling information for scheduling multiple cells in the MAC CE, which is equivalent to the scheduling information in the MC-DCI.

[0054] It should be noted that the first information can include a MAC CE, and can also include other information, for example, a DCI, that is, the scheduling information in the legacy DCI can schedule a DCI, and the scheduled DCI carries scheduling information for scheduling multiple cells. The DCI scheduled by the scheduling information in the legacy DCI can be located in the PDCCH, or can be carried in the PDSCH in the form of data.

[0055] Figure 2 is an application diagram of a scheduling information receiving method according to an embodiment of the present disclosure.

[0056] As shown in Figure 2 , taking three cells Cell#0, Cell#1 and Cell#2 as an example. The network device can send a legacy DCI to the terminal in Cell#0, and carry scheduling information for scheduling Cell#1 and Cell#2 in the MAC CE scheduled by the legacy DCI.

[0057] After the terminal receives the legacy DCI sent by the network device in Cell#0, it can determine the MAC CE scheduled by the legacy DCI (for example, the scheduled cell is Cell#0), and then receive the MAC CE in Cell#0, and obtain the scheduling information for scheduling Cell#1 and Cell#2 from the received MAC CE, for example, for scheduling PDSCH in Cell#1 and Cell#2. According to the scheduling information for scheduling Cell#1 and Cell#2, the terminal can receive PDSCH in Cell#1 and Cell#2.

[0058] It should be noted that since the terminal needs to consume a period of time t from determining successful reception of the MAC CE to parsing the MAC CE to determine the scheduling information in the MAC CE for scheduling Cell#1 and Cell#2, the effective time of the scheduling information in the MAC CE is at least after the time of successfully receiving the MAC CE plus the duration t. For example, if the terminal determines successful reception of the MAC CE at time slot n, the terminal can confirm the scheduling information of Cell#1 and Cell#2 after t+time slot n.

[0059] Figure 3 is another schematic flow chart of a scheduling information receiving method according to an embodiment of the present disclosure. As shown in Figure 3 , the scheduling information for scheduling multiple cells includes at least one type of information field, and the same type corresponds to one information field, and the method further includes:

[0060] In step S301, a first association relationship between a value of a same type of information field in the scheduling information used for scheduling multiple cells and multiple scheduling information, and a second association relationship between the multiple scheduling information and multiple scheduled cells are determined.

[0061] In step S302, the scheduling information of each of the scheduled cells is determined according to the first association relationship and the second association relationship.

[0062] In an embodiment, multiple types of information fields can be included in the DCI, such as a frequency domain resource assignment (FDRA) field, a zero power channel information reference signal trigger (ZP CSI-RS trigger) field, a bandwidth part indicator field, and the like.

[0063] For the DCI of the existing mechanism, one type of information field can schedule one cell, for example, the FDRA information field can schedule the frequency domain resource of the target cell.

[0064] The embodiment can be applied in a scenario where the legacy DCI schedules first information, the first information carries scheduling information used for scheduling multiple cells, and the scheduling information used for scheduling multiple cells schedules multiple cells.

[0065] In the embodiment, the network device can send the legacy DCI to the terminal, the legacy DCI carries scheduling information, the scheduling information is used for scheduling the first information, the first information carries scheduling information used for scheduling multiple cells, and the scheduling information used for scheduling multiple cells can schedule multiple cells (i.e., scheduled cells). Specifically, a value of a specific information field in the scheduling information used for scheduling multiple cells (a value of one information field, rather than values of multiple information fields) can be associated with multiple scheduling information (i.e., one information field value is associated with multiple scheduling information), for example, a first association relationship, and multiple scheduling information can be associated with multiple scheduled cells, for example, a second association relationship. The multiple scheduling information types corresponding to the value of one type of information field are the same, for example, the frequency domain resource FDRA corresponding to different cells, for example, the BWP index configured for different cells.

[0066] This indication mode can be referred to as combined or shared indication, for example, for a specific value of a specific type of information field in a DCI, multiple scheduling information can be associated, and the multiple scheduling information is associated with multiple scheduled cells.

[0067] The first association relationship and the second association relationship can be determined by a predefined manner or by a signaling indication manner. Taking the signaling indication manner as an example, the network side can define, based on signaling indication (for example, radio resource control (RRC) signaling), a first association relationship between a specific value of a specific type of information field in scheduling information for scheduling multiple cells and multiple scheduling information. The signaling can be signaling configured for a cell receiving a legacy DCI. Taking RRC signaling as an example, a terminal receives corresponding RRC signaling in a cell receiving a legacy DCI, and the RRC signaling indicates an association relationship between a specific value of a specific type of information field in scheduling information for scheduling multiple cells and multiple scheduling information. The number of bits occupied by the specific type of information field is related to the range of the indication value configured by the RRC signaling.

[0068] Taking a BWP indication field in scheduling information for scheduling multiple cells as an example, in a DCI for scheduling three cells (cell id numbers are 0, 1, and 2, respectively), the corresponding DCI is received in cell 0.

[0069] For example, the first association relationship is determined by a signaling indication manner, and the terminal receives corresponding RRC signaling in cell 0 to determine a first association relationship between a value of a BWP indication field in scheduling information for scheduling multiple cells and multiple cell configuration BWP ids. For example, for the BWP indication field, the first association relationship can be as shown in Table 1:

[0070]

[0071] Table 1

[0072] As shown in Table 1, the number of bits occupied by the BWP indication field is log2(4) = 2, and in the case where the value of the BWP indication field is 01, according to the first association relationship, it can be determined that the value 01 of the BWP indication field is associated with three scheduling information, the first scheduling information is BWP id = 2, the second scheduling information is BWP id = 3, and the third scheduling information is BWP id = 1. Further, 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, so 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.

[0073] For the information field of the characteristic type in the scheduling information used for scheduling multiple cells, the value of the information field can be associated with the scheduling information n scheduling information, n is equal to the number of scheduled cells, wherein the scheduling information the scheduling information of cell k1, the scheduling information of cell k j , and so on, the scheduling information of cell k n , wherein k j is the cell id number.

[0074] The terminal can determine the first association relationship between the value of a specific information field in the scheduling information used for scheduling multiple cells and multiple scheduling information, and the second association relationship between the multiple scheduling information and the multiple scheduled cells, and then can determine the multiple scheduling information corresponding to the value of the specific information field in the scheduling information used for scheduling multiple cells according to the first association relationship, and determine the scheduled cell corresponding to each scheduling information according to the second association relationship, and further determine the scheduling information of each scheduled cell. Thus, on the basis that the network device schedules multiple cells through the scheduling information used for scheduling multiple cells, the terminal can accurately interpret the scheduling information of each cell indicated by the scheduling information used for scheduling multiple cells. The specific implementation of the first association relationship is mainly introduced above, and the determination relationship corresponding to the second association relationship will be expanded below.

[0075] It should be noted that the multiple cells scheduled by the scheduling information used for scheduling multiple cells, that is, the multiple scheduled cells, can be determined by the terminal according to the CIF (Cell Indicator Field, cell indication field) in the scheduling information used for scheduling multiple cells, can also be agreed with the network device in advance, and can also be determined according to a predefined rule (for example, a protocol agreement), and the present disclosure is not limited.

[0076] In one embodiment, the determination of the first association relationship between the value of a specific information field in the scheduling information used for scheduling multiple cells and multiple scheduling information includes determining the first association relationship according to the indication of the network device. For example, the network device can determine the association relationship between the value of an information field (a certain information field, not multiple information fields) in the DCI and multiple scheduling information, and then indicate the terminal through RRC (Radio Resource Control, Radio Resource Control) signaling. Of course, it can also be determined according to a predefined rule, for example, determined based on a protocol agreement.

[0077] In one embodiment, the determination of the second association relationship between the multiple scheduling information and the multiple scheduled cells includes determining the second association relationship according to a predefined rule.

[0078] The first association relationship between the value of a specific information field in the scheduling information for scheduling multiple cells and multiple scheduling information, and the second association relationship between the multiple scheduling information and the multiple scheduled cells, can be predefined rules, for example, agreed by protocol, or indicated by a network device, wherein the manner of indicating the association relationship by the network device includes but is not limited to indicating by RRC signaling, indicating by DCI, and indicating by MAC CE. The number of bits occupied by the information field in the scheduling information for scheduling multiple cells is determined by the number of values determined in a manner based on signaling indication or predefinition. For example, if the first association relationship defines the values of N information fields, and the value of each information field is associated with multiple scheduling information, the number of bits occupied by the information field in the scheduling information for scheduling multiple cells is equal to log2(N).

[0079] The following embodiments are mainly exemplarily described for the case where the second association relationship is predefined.

[0080] In one embodiment, the scheduling information for scheduling multiple cells includes n scheduling information, and the multiple scheduled cells include n scheduled cells; the predefined rule defines that the jth scheduling information in the n scheduling information is associated with the jth scheduled cell in the n scheduled cells, wherein 1≤j≤n.

[0081] The scheduled cells can include the cell where the terminal receives the legacy DCI and other cells (cells other than the cell where the terminal receives the legacy DCI), or can not include the cell where the terminal receives the legacy DCI, and only include other cells. In this embodiment, the predefined rule can not distinguish between the cell where the terminal receives the legacy DCI and other cells when defining the association relationship between the scheduled cells and the scheduling information, and the same rule is used to define the association relationship between the cell where the terminal receives the legacy DCI and other cells and the scheduling information.

[0082] Taking n scheduled cells as an example, n scheduling information can be determined according to the first association relationship and the value of the information field in the scheduling information for scheduling multiple cells, and the corresponding relationship between the n scheduling information and the n scheduled cells can be determined according to the second association relationship. The second association relationship can be that the jth scheduling information in the n scheduling information is associated with the jth scheduled cell in the n scheduled cells.

[0083] Accordingly, the terminal can determine the jth scheduling information as the scheduling information of the jth scheduled cell, so that on the basis of the network device scheduling multiple cells by scheduling information of the multiple cells, the terminal can accurately interpret the scheduling information of each cell indicated by the scheduling information of the multiple cells.

[0084] For example, for the n scheduled cells of the 1st cell to the nth scheduled cell, taking the combine indication mode of the FDRA field as an example, according to the value of the FDRA field and the first association relationship, n scheduling information can be determined, for example to where k j is the cell id number. In this embodiment, the terminal can determine the 1st scheduling information as the frequency domain scheduling information of the 1st scheduled cell (cell k1), the 2nd scheduling information as the frequency domain scheduling information of the 2nd scheduled cell (cell k2), …, the jth scheduling information as the frequency domain scheduling information of the jth scheduled cell (cell k j ), and the nth scheduling information as the frequency domain scheduling information of the nth scheduled cell (cell k n ), so that on the basis of scheduling multiple cells by scheduling information of the multiple cells, the terminal can accurately interpret the frequency domain scheduling information of each cell indicated by the scheduling information of the multiple cells.

[0085] For example, for the n scheduled cells of the 1st cell to the nth scheduled cell, taking the combine indication mode of the ZP CSI-RS trigger field as an example, according to the value of the ZP CSI-RS trigger field and the first association relationship, n scheduling information can be determined, for example to where k j is the cell id number. In this embodiment, the terminal can determine the 1st scheduling information as the ZP CSI-RS trigger information of the 1st scheduled cell (cell k1), the 2nd scheduling information as the ZP CSI-RS trigger information of the 2nd scheduled cell (cell k2), …, the jth scheduling information as the ZP CSI-RS trigger information of the jth scheduled cell (cell k j ), and the nth scheduling information as the ZP CSI-RS trigger information of the nth scheduled cell (cell k n ), so that on the basis of scheduling multiple cells by scheduling information of the multiple cells, the terminal can accurately interpret the ZP CSI-RS trigger information of each cell indicated by the scheduling information of the multiple cells.

[0086] For example, for the n scheduled cells of the 1st cell to the nth scheduled cell, taking the combine indication mode of the BWP indication field as an example, according to the value of the BWP indication field and the first association relationship, n scheduling information can be determined, for example to wherein k j is a cell id number. In the embodiment, the terminal can determine, according to the second association relationship, that the 1st scheduling information is the BWP information of the 1st scheduled cell (cell k1), the 2nd scheduling information is the BWP information of the 2nd scheduled cell (cell k2), …, the jth scheduling information is the BWP information of the jth scheduled cell (cell k j ), and the nth BWP scheduling information is the BWP information of the nth scheduled cell (cell k n ), so that on the basis of scheduling multiple cells by scheduling information, the terminal can accurately interpret the BWP information of each cell indicated by the scheduling information of scheduling multiple cells.

[0087] wherein the order of the multiple scheduled cells is explained in subsequent embodiments.

[0088] The following is explained by several embodiments, and the pre-defined rule specifies the association relationship between the cell where the terminal receives the legacy DCI and other cells and the information field according to the same rule, and how to determine the order of the multiple scheduled cells.

[0089] In one embodiment, the pre-defined rule specifies that the identification of the jth scheduled cell is less than the identification of the j+1th scheduled cell, for example, k j is less than k j+1 ; or the pre-defined rule specifies that the identification of the jth scheduled cell is greater than the identification of the j+1th scheduled cell, for example, k j is greater than k j+1 .

[0090] In one embodiment, the terminal can determine the identification (for example, Cell ID) of the scheduled cell according to the RRC signaling sent by the network device, for example, according to the information elements (Information Element, IE) such as ServcellIndex and / or SCellIndex in the RRC signaling; and if the identification of the cell corresponds to the PCI (Physical Cell Identity), it can be determined according to the information element PhysCellId in the RRC signaling; of course, it can also be determined according to other signaling. Or, it can be determined according to other ways, for example, it can be specified by the pre-defined rule.

[0091] The predefined rule can specify that the scheduled cells are sorted according to their identities, for example, can be sorted in ascending order of the identity, so that the identity of the jth scheduled cell is less than the identity of the j+1th scheduled cell, or sorted in descending order of the identity, so that the identity of the jth scheduled cell is greater than the identity of the j+1th scheduled cell.

[0092] For example, taking 4 scheduled cells as an example, which are cell #1 with an identity of 1, cell #2 with an identity of 2, cell #3 with an identity of 3, and cell #4 with an identity of 4. If sorted in ascending order of the identity, then k j < k j+1 The first cell can be determined as cell #1, the second scheduled cell as cell #2, the third cell as cell #3, and the fourth cell as cell #4; if sorted in descending order of the identity, then k j > k j+1 The first cell can be determined as cell #4, the second scheduled cell as cell #3, the third cell as cell #2, and the fourth cell as cell #1.

[0093] Accordingly, the order of the cells can be accurately determined according to the identity of the cell, and then the jth information field can be determined as the scheduling information of the jth scheduled cell.

[0094] Figure 4 is a schematic flowchart of another method for receiving scheduling information according to an embodiment of the present disclosure. As Figure 4 shown, the scheduling information for scheduling multiple cells includes at least one type of information field, and the same type corresponds to multiple information fields. The method further includes:

[0095] In step S401, the association between the multiple information fields of the same type in the scheduling information for scheduling multiple cells and the multiple scheduled cells is determined.

[0096] In step S402, the scheduling information of each of the scheduled cells is determined according to the value of each of the information fields and the association.

[0097] For the existing mechanism of DCI, generally only one information field of the same type is included, and one cell can be scheduled according to the information field of this type, for example, the FDRA information field can schedule the frequency domain resource of the target cell.

[0098] The embodiment can be applied in a scenario where a legacy DCI schedules first information, the first information carries scheduling information for scheduling multiple cells, and the scheduling information for scheduling multiple cells schedules multiple cells.

[0099] In this embodiment, the network device can send a legacy DCI to the terminal, and the legacy DCI carries scheduling information, and the scheduling information is used for scheduling first information, and the first information carries scheduling information used for scheduling multiple cells, and the scheduling information used for scheduling multiple cells can schedule multiple cells (that is, scheduled cells), and one possible design is as follows: for one or more types of information fields in the scheduling information used for scheduling multiple cells, for multiple scheduled cells, multiple information fields of the same type can be set in the scheduling information used for scheduling multiple cells, and each information field can schedule one cell. The same type of information field corresponds to the same type of information indicated, for example, frequency domain resource FDRA indicating different cells, for example, BWP index indicating different cell configurations.

[0100] This indication method can be called a separate method, for example, a specific type of information field in the scheduling information used for scheduling multiple cells can include multiple information fields. Based on the information field scheduling a single cell, the specific type of information field can be expanded according to the number of scheduled cells to obtain multiple information fields of the same type, wherein different information fields indicate messages of different cells. The number of bits occupied by the multiple information fields of the same type is equal to the sum of the number of bits occupied by the above information field corresponding to each scheduled cell (of course, it can be set to equal to other quantities as needed). The number of bits occupied by the above information field corresponding to each scheduled cell can be the same as the number of bits occupied by the same type of information field in the DCI scheduling one cell in the existing mechanism, or can be the same as the maximum value of the number of bits occupied by the same type of information field in the DCI scheduling one cell in the existing mechanism.

[0101] Figure 5 is a schematic flow chart of a scheduling information sending method according to an embodiment of the present disclosure. The scheduling information sending method shown in this embodiment can be performed by a network device, which can communicate with a terminal, and the network device includes but is not limited to a base station in a communication system such as a 4G base station, a 5G base station, a 6G base station, etc., and the terminal includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, etc.

[0102] As shown in Figure 5 , the scheduling information sending method can include the following steps:

[0103] In step S501, a legacy DCI is sent to the network device, wherein the legacy DCI carries scheduling information, and the scheduling information is used for scheduling at least first information, and the first information carries scheduling information used for scheduling multiple cells.

[0104] In an embodiment, the network device can send a legacy DCI to the terminal, and the scheduling information can be carried in the legacy DCI, wherein the first information can be scheduled by the scheduling information, for example, the time domain resource and the frequency domain resource indicating the first information, and the scheduling information for scheduling multiple cells can be carried in the first information.

[0105] The scheduling information for scheduling a single cell is equivalent to the scheduling information in the legacy DCI, and the scheduling information for scheduling multiple cells is equivalent to the scheduling information in the MC-DCI. That is, the terminal can determine the scheduling information in the legacy DCI by blind detection of the PDCCH, determine the scheduling information in the MC-DCI according to the first information scheduled by the legacy DCI, and reduce the types of DCI to be obtained, which is beneficial to reduce the blind detection complexity.

[0106] Although the terminal needs to determine the first information scheduled by the scheduling information in the legacy DCI to determine the scheduling information for scheduling multiple cells carried in the first information, the terminal can directly determine the first information according to the time domain resource and the frequency domain resource directly indicated by the scheduling information in the legacy DCI without blind detection, so the blind detection complexity is relatively low. Therefore, the embodiment of the present disclosure determines the first information according to the scheduling information, and then obtains the scheduling information for scheduling multiple cells from the first information, which is relatively low in complexity compared with blind detection of the MC-DCI from the PDCCH. Moreover, since only the legacy DCI needs to be carried in the PDCCH, the scheduling information for scheduling multiple cells is determined according to the information scheduled by the legacy DCI, so the MC-DCI does not need to be carried in the PDCCH, which is beneficial to reduce the number of DCI sizes in the PDCCH and improve the transmission performance.

[0107] It should be noted that the scheduling information for scheduling multiple cells is equivalent to the scheduling information in the MC-DCI, and is also equivalent to the scheduling information in multiple legacy DCIs for scheduling multiple cells. In the embodiment of the present disclosure, the scheduling information for scheduling multiple cells is equivalent to the scheduling information in the MC-DCI, mainly to distinguish when the MC-DCI is carried in the PDCCH, and not to mean that the scheduling information for scheduling multiple cells is the MC-DCI, that is, the legacy DCI is carried in the PDCCH, and the first information scheduled according to the legacy DCI can determine the scheduling information for scheduling multiple cells. 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.

[0108] In one embodiment, the scheduling information carried by the legacy DCI is used to schedule at least one of the following cells:

[0109] The cell for sending the legacy DCI;

[0110] The cell corresponding to the preset cell identifier in the cell that can be scheduled by the legacy DCI;

[0111] The cell indicated by the network device.

[0112] The cell scheduled by the scheduling information carried in the legacy DCI sent by the network device to the terminal can be determined according to the protocol agreement or autonomously determined by the network indication, and then the terminal is informed through the indication information.

[0113] For example, the protocol agreement stipulates that the cell is the cell for sending the legacy DCI by the network device, and then the network device can determine that the cell scheduled by the legacy DCI sent to the terminal is the cell for sending the legacy DCI. Further, the network device can send the first information to the terminal in the cell for sending the legacy DCI, and carry the scheduling information for scheduling multiple cells through the first information.

[0114] For example, the protocol agreement stipulates that the cell scheduled by the legacy DCI includes the cell corresponding to the preset cell identifier in the cell that can be scheduled by the legacy DCI, for example, the cell corresponding to the smallest cell identifier or the cell corresponding to the largest cell identifier. Then the network can determine that the cell scheduled by the legacy DCI sent to the terminal is the cell corresponding to the preset cell identifier in the cell that can be scheduled by the legacy DCI. Further, the network device can send the first information to the terminal in the cell corresponding to the preset cell identifier, and carry the scheduling information for scheduling multiple cells through the first information.

[0115] For example, the network device can autonomously determine a cell scheduled by the legacy DCI sent to the terminal according to needs, and then indicate the cell scheduled by the scheduling information carried in the legacy DCI by sending indication information to the terminal. Further, the network device can send first information to the terminal in the indicated cell, and carry scheduling information for scheduling multiple cells in the first information.

[0116] In one embodiment, the first information includes a medium access control layer control element (MAC CE).

[0117] The network device can send a legacy DCI to the terminal, and carry scheduling information for scheduling a single cell in the legacy DCI. The scheduling information can be used to schedule a MAC CE, for example, indicating the time domain resource and frequency domain resource of the MAC CE, and the MAC CE can carry scheduling information for scheduling multiple cells.

[0118] On this basis, the network device only needs to carry the legacy DCI in the PDCCH, and then determines the MAC CE according to the scheduling information in the legacy DCI, and obtains the scheduling information for scheduling multiple cells from the MAC CE, so that the PDCCH can not have to carry the MC-DCI, and the terminal only needs to perform blind detection on the legacy DCI in the PDCCH, and then determine the MAC CE scheduled by the legacy DCI, and then obtain the scheduling information for scheduling multiple cells in the MAC CE, which is equivalent to the scheduling information in the MC-DCI.

[0119] It should be noted that the first information can include not only the MAC CE, but also other information, for example, a DCI, that is, the scheduling information in the legacy DCI can schedule the DCI, and the scheduled DCI can be carried in the PDSCH, not necessarily in the PDCCH.

[0120] Figure 6 is another schematic flowchart of a method for sending scheduling information according to an embodiment of the present disclosure. As shown in Figure 6 The scheduling information for scheduling multiple cells includes at least one type of information field, and one information field corresponds to one type. The method further includes:

[0121] In step S601, a first association relationship between a value of an information field of the same type in the scheduling information for scheduling multiple cells and multiple scheduling information of the same type, and a second association relationship between the multiple scheduling information and multiple scheduled cells are determined.

[0122] In step S602, the first information is generated according to the first association relationship and the second association relationship.

[0123] In an embodiment, multiple types of information fields can be included in the DCI, such as FDRA field, ZP CSI-RS trigger field, partial bandwidth indication field, etc.

[0124] For the DCI of the existing mechanism, one type of information field can schedule one cell, such as the FDRA information field can schedule the frequency domain resource of the target cell.

[0125] The embodiment can be applied in the scenario that the legacy DCI schedules the first information, and the first information carries the scheduling information for scheduling multiple cells.

[0126] In the embodiment, the network device can send the legacy DCI to the terminal, and the legacy DCI carries the scheduling information, the scheduling information is used for scheduling the first information, the first information carries the scheduling information for scheduling multiple cells, and the scheduling information for scheduling multiple cells can schedule multiple cells (i.e., scheduled cells). Specifically, the value of a specific information field in the scheduling information for scheduling multiple cells (the value of one information field, rather than the values of multiple information fields) can be associated with multiple scheduling information (i.e., one information field value is associated with multiple scheduling information), for example, referred to as a first association relationship, and multiple scheduling information can be associated with multiple scheduled cells, for example, referred to as a second association relationship. The multiple scheduling information types corresponding to one type of information field value are the same, for example, the frequency domain resource FDRA corresponding to different cells, for example, the BWP index configured for different cells.

[0127] This indication manner can be referred to as combined or shared indication, for example, for a specific value of a specific type of information field in a DCI, multiple scheduling information can be associated, and the multiple scheduling information is associated with multiple scheduled cells.

[0128] The first association relationship and the second association relationship can be determined in a predefined manner or in a manner indicated by signaling. Taking the manner indicated by signaling as an example, the network side can define, based on signaling (for example, radio resource control (RRC) signaling), a specific value indicated by a specific type of information field in scheduling information used for scheduling multiple cells and a first association relationship of multiple scheduling information. The signaling can be signaling configured for a cell receiving legacy DCI. Taking RRC signaling as an example, a terminal receives corresponding RRC signaling in a cell receiving legacy DCI, and the RRC signaling indicates an association relationship of a specific value indicated by a specific type of information field in scheduling information used for scheduling multiple cells and multiple scheduling information. The number of bits occupied by the specific type of information field is related to the range of the indicated value configured by the RRC signaling.

[0129] Figure 7 FIG. 7 is a schematic flowchart of another method for transmitting scheduling information according to an embodiment of the present disclosure. As shown in FIG. 7, the scheduling information used for scheduling multiple cells includes at least one type of information field, and the same type corresponds to multiple information fields. The method further includes the following steps. Figure 7

[0130] In step S701, an association relationship between multiple information fields of the same type in the scheduling information used for scheduling multiple cells and multiple scheduled cells is determined.

[0131] In step S702, the first information is generated according to the association relationship.

[0132] In one embodiment, multiple types of information fields can be included in the DCI, such as an FDRA field, a ZP CSI-RS trigger field, a partial bandwidth indication field, and the like.

[0133] In the existing DCI, only one information field of the same type is generally included, and one cell can be scheduled according to the information field of this type, for example, the frequency domain resource of a cell can be scheduled by the FDRA information field.

[0134] The present embodiment can be applied in a scenario in which a legacy DCI schedules first information, the first information carries scheduling information used for scheduling multiple cells, and the scheduling information used for scheduling multiple cells schedules multiple cells.

[0135] ​In the embodiment, the network device can determine the association between the multiple information fields of the same type and the multiple scheduled cells, and then set the information field of each cell according to the association, thereby generating the scheduling information for scheduling the multiple cells, and sending the scheduling information for scheduling the multiple cells to the terminal, so as to realize the scheduling of the multiple cells. The information fields of the same type correspond to the same information type, for example, the frequency domain resource FDRA indicating different cells, for example, the BWP index indicating the configuration of different cells.

[0136] The indication mode can be called separate indication, for example, a specific type of information field in the scheduling information for scheduling multiple cells can include multiple information fields. Based on the information field of scheduling a single cell, the specific type of information field can be expanded according to the number of scheduled cells, so as to obtain multiple information fields of the same type, wherein different information fields indicate messages of different cells. The number of bits occupied by the multiple information fields of the same type is equal to the sum of the number of bits occupied by the above information field corresponding to each scheduled cell (of course, it can be set to equal to other quantities according to needs). The number of bits occupied by the above information field corresponding to each scheduled cell is 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.
