Description

Technical Field

[0001] The present disclosure relates to the field of communications, and in particular, to resource determination, multi-carrier scheduling methods and apparatuses, and storage media.

Background Art

[0002] The new radio (NR) technology of the 5th Generation Mobile Communication Technology (5G) operates in a relatively wide spectrum range. By re-farming the corresponding frequency band of the existing cellular network, the utilization rate of the corresponding spectrum gradually increases. However, in the case of Frequency Range 1 (FR1), the available frequency domain resources are gradually fragmented. To meet the needs of various spectra, it is necessary to utilize these dispersed spectrum resources in a higher spectrum, power-efficient, and more flexible manner to achieve higher network throughput and good coverage.

[0003] Based on the related mechanism, one downlink control information (DCI) in the existing serving cell can only schedule the data of one cell. As the frequency resources are gradually fragmented, the need to schedule the data of multiple cells simultaneously gradually increases. Therefore, it is necessary to introduce DCI for scheduling the data of multiple cells.

[0004] In the Release-18 (Rel-18) scenario, a single DCI can schedule three or more cells simultaneously. When based on the methods of related technologies, simply expanding the Frequency Domain Resource Allocation (FDRA) field in the DCI will significantly increase the number of bits occupied by the FDRA field, increase the bit overhead of the DCI, and reduce the DCI transmission resources.

Best Mode for Carrying Out the Invention

[0040] In this specification, exemplary embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings refer to the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments that are consistent with the present invention. Rather, they are merely examples of devices and methods that are consistent with the aspects of the present invention detailed in the appended claims.

[0041] The terms used in this disclosure are for the sole purpose of describing particular embodiments and are not intended to limit the disclosure. When used in this disclosure and the appended claims, the singular forms "one," "the," and "this" are to be construed to include the plural forms as well, unless the context clearly dictates otherwise. Also, the term "and / or" as used herein refers to and is understood to cover any and all possible combinations of at least one of the associated listed items.

[0042] In this disclosure, terms such as first, second, third, etc. can be used to describe various information, but it is understood that the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this 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 "case" as used herein may be interpreted as "when," "if," or "depending on the determination."

[0043] Based on the relevant mechanism, only one DCI within a scheduling cell is permitted to schedule the data transmission of one cell. That is, only scheduling of the Physical Uplink Shared Channel (PUSCH) or the Physical Downlink Shared Channel (PDSCH) of one cell is permitted. As the frequency resources gradually fragment, the need to schedule the data of multiple cells simultaneously gradually increases. At the same time, in order to reduce the overhead of control signaling, the Rel-18 WID supports a single DCI to schedule the PDSCH or PUSCH of multiple cells. Note that each cell corresponds to one PDSCH and one PUSCH. For example, Fig. 1A shows the situation of scheduling the PDSCH of three cells via one DCI.

[0044] In the scenario where a single DCI schedules data transmission for multiple cells, how to reduce the DCI overhead as much as possible while ensuring scheduling flexibility is an issue that needs to be urgently solved. The FDRA field is used to indicate the frequency-domain resources for data transmission of a cell. In the scenario design where a single DCI in Rel-17 schedules two cells, it has been proposed that the DCI FDRA field can be simply extended, that is, the frequency-domain information of the scheduling data for the two cells can be indicated based on different bits.

[0045] In the Rel-18 scenario, a single DCI can schedule three or more cells simultaneously. If based on the above method, simply extending the FDRA field will significantly increase the number of bits occupied by the FDRA field and increase the DCI bits overhead. Taking the example where a single DCI schedules three cells and the number of RBs occupied by the BWP set for each cell is 100, when the FDRA field corresponding to the three cells is based on resource type1, the number of bits occupied by the corresponding FDRA field is 39, which significantly increases the DCI overhead and reduces the DCI transmission resources.

[0046] In the related mechanism, there are three types of FDRA field resource allocation types set based on Radio Resource Control (RRC) signaling: type0, type1, and dynamic.

[0047] Here, type0 indicates, through a bitmap, that a resource block group (RBG) corresponding to PDSCH or PUSCH is transmitted within the bandwidth part (BWP) range. The RBG is composed of P consecutive RBs, and the size of P is related to the BWP size and RBG configuration. The BWP size is determined by the number of RBs occupied by the BWP. The correspondence is as shown in Table 1, for example.

[0048]

Table 1

[0049] Assume that in the type0 method, the BWP size is 25 and the configuration identifier is 2. Then P is 4. Assuming that the indicated value of the FDRA field is 1001011, the RBG indexes for data transmission of the correspondingly indicated cell are shown in Figure 1B, which are RBG#0, RBG#3, RBG#5, and RBG#6 respectively.

[0050] Here, type1 determines the frequency domain resources for transmitting PDSCH or PUSCH within the BWP by adding the duration to the start position, and the frequency domain resources are continuously allocated in the frequency domain.

[0051] Referring to Figure 1C, assume that the BWP size is 25, the start RB index of the frequency domain resources for data transmission of the cell determined by type1 is RB#7, and the duration is 9. Then all of RB#7 to RB#15 can be used as the frequency domain resources for data transmission. Here, under the condition that the FDRA field resource allocation type set by RRC signaling is dynamic, the terminal can realize dynamic switching between resource allocation types type0 and type1 based on the indication of the most significant bit (MSB) of the FDRA field.

[0052] When the MSB indicates 0, the corresponding FDRA field is of type0 resource allocation type, and when the MSB indicates 1, the corresponding FDRA field is of type1 resource allocation type. The length of the FDRA field in DCI is determined based on the resource allocation method with the longer occupied FDRA field among the two resource allocation methods.

[0053] It should be understood that the RB mentioned in this disclosure can refer to a physical resource block (PRB), a virtual resource block (VRB), or a general term for PRB and VRB, but this disclosure is not limited thereto.

[0054] In the case of DCI for scheduling multiple cells, simply expanding the FDRA field will significantly increase the DCI bits overhead and reduce the DCI transmission efficiency.

[0055] To solve the above technical problems, this disclosure provides a resource determination, multi - carrier scheduling method and apparatus, and a storage medium. It ensures the flexibility scheduled by DCI, reduces the DCI bit overhead, effectively avoids the problem of reduced DCI transmission efficiency, and has high availability.

[0056] The following first describes the resource determination method provided by this disclosure from the terminal side. Embodiments of this disclosure provide a resource determination method. Referring to FIG. 2, FIG. 2 is a flowchart of a resource determination method according to an embodiment. This method can be executed by a terminal and includes the following steps. In step 201, receive the downlink control information DCI transmitted by the base station, where the DCI is used to schedule data transmission of a plurality of cells.

[0057] In an embodiment of the present disclosure, the DCI is used to schedule data transmission of a plurality of cells, and includes, but is not limited to, scheduling the PDSCH of a plurality of cells and / or the PUSCH of a plurality of cells. Here, each cell corresponds to one PDSCH and / or each cell corresponds to one PUSCH.

[0058] In step 202, determine the resource allocation type of the first cell. In an embodiment of the present disclosure, the first cell may be any one of the plurality of cells. The resource allocation type of the first cell may be determined through RRC signaling transmitted by the base station, and the resource allocation type of the first cell may be type0, type1, or dynamic.

[0059] In step 203, determine the frequency domain resources for data transmission of the first cell based on at least the resource allocation type of the first cell and the indication value of the frequency domain resource allocation FDRA field in the DCI.

[0060] In the above embodiment, it ensures the flexibility scheduled by the DCI, reduces the DCI bit overhead, effectively avoids the problem of reduced DCI transmission efficiency, and has high availability.

[0061] In some optional embodiments, in a scenario of scheduling a plurality of cells via DCI, a terminal may jointly determine frequency-domain resource for data transmission of a first cell based on the RBG granularity of the first cell, the resource allocation type of the first cell, and the indicated value of the FDRA field. Here, the first cell may be any one of the plurality of cells scheduled by DCI.

[0062] Referring to FIG. 3, FIG. 3 is a flowchart of a resource determination method according to an embodiment. This method can be executed by a terminal and includes the following steps.

[0063] In step 301, receive downlink control information DCI transmitted by a base station, where the DCI is used to schedule data transmission of a plurality of cells.

[0064] In an embodiment of the present disclosure, DCI is used to schedule data transmission of a plurality of cells, and includes, but is not limited to, scheduling PDSCH of a plurality of cells and / or PUSCH of a plurality of cells. Here, each cell corresponds to one PDSCH and / or each cell corresponds to one PUSCH.

[0065] In step 302, determine the resource allocation type of the first cell. In an embodiment of the present disclosure, the first cell may be any one of the plurality of cells. The resource allocation type of the first cell may be determined through RRC signaling transmitted by the base station, and the resource allocation type of the first cell may be type0, type1, or dynamic.

[0066] In step 303, determine the resource block group (RBG) granularity of the first cell.

[0067] In an embodiment of the present disclosure, the RBG granularity P of the first cell can be determined according to the BWP size and the configuration identifier indicated by the RRC signaling transmitted by the base station.

[0068] In an embodiment of the present disclosure, the execution order of step 302 and step 303 is not limited.

[0069] In step 304, based on the RBG granularity of the first cell, the resource allocation type of the first cell, and the indication value of the FDRA field, the frequency domain resources for data transmission of the first cell are determined.

[0070] In the above embodiment, by combining the RBG granularity of the first cell, the resource allocation type of the first cell, and the indication value of the FDRA field, the frequency domain resources for data transmission of the first cell can be determined. It can ensure the flexibility scheduled by DCI, reduce the DCI bit overhead, effectively avoid the problem of reduced DCI transmission efficiency, and has high availability.

[0071] Regarding the above step 303, in a possible implementation form, the RBG granularity of the first cell is determined based on the first correspondence relationship among the number range of the first RBs, the candidate configuration identifier, and the candidate RBG granularity.

[0072] Here, the number range of the first RBs is the number range to which the number of RBs occupied by the sub-bandwidth BWP set in the first cell belongs.

[0073] In the first correspondence relationship, the number range of the first RBs corresponds to three or more candidate configuration identifiers, and each candidate configuration identifier corresponds to one of the candidate RBG granularities.

[0074] That is, the present disclosure can extend the correspondence relationship shown in Table 1. For example, as shown in Table 2, at least the configuration3 setting can be added.

[0075]

Table 2

[0076] Here, the candidate RBG granularity corresponding to configuration3 may be greater than or equal to the candidate RBG granularity corresponding to configuration2. That is, P 31 may be greater than or equal to 4, and P 32 may be greater than or equal to 8, and so on. When Table 2 also includes configuration4, the candidate RBG granularity corresponding to configuration4 may be greater than or equal to the candidate RBG granularity corresponding to configuration3.

[0077] The terminal determines the number range of the first RBs based on the number of RBs occupied by the BWP set in the first cell, and further jointly determines the RBG granularity P of the first cell through the correspondence in Table 2 according to the number range of the first RBs and the candidate configuration identifier indicated by the base station through RRC signaling.

[0078] In another possible implementation, the RBG granularities of multiple cells are the same, and based on this, the RBG granularities of the multiple cells are determined based on a second correspondence among the number range of the second RBs, the candidate setting identifier, and the candidate RBG granularity.

[0079] Here, the number range of the second RBs is the number range to which the sum or average value of the number of RBs occupied by the BWP set in the multiple cells belongs.

[0080] For example, assuming that the number of RBs occupied by the configured BWP of three cells is 25, 37, and 76 respectively, the average value is 46, which belongs to the number range 2 of RBs, and the candidate setting identifier is 1, then based on the second correspondence, the RBG granularities of the three cells are the same and can be determined to be equal to P 12 and P 12Assuming that the value of [[ID=]] is 4, the RBG granularity of these three cells will all be 4.

[0081] Optionally, in the second correspondence relationship, for example, as shown in Table 3, the number range of the second RB corresponds to three or more candidate setting identifiers, and each of the candidate setting identifiers is used to determine one of the candidate RBG granularities.

[0082]

Table 3

[0083] In Table 3, the number range of the second RB is the number range to which the sum or average value of the number of RBs occupied by the BWP set for the plurality of cells belongs. In addition, when the number range of the second RB is the number range to which the average value of the number of RBs occupied by the BWP set for a plurality of cells belongs, exemplarily, the number range of the second RB in Table 3 (represented by the average BWP size) may be the same as the range of values corresponding to the BWP size in Table 2. Correspondingly, the RBG granularities corresponding to Settings 1, 2, 3, etc. in Table 3 may also be the same as the RBG granularities corresponding to Settings 1, 2, 3, etc. in Table 2.

[0084] Optionally, in the second correspondence relationship, for example, as shown in Table 4, the number range of the second RB corresponds to two or more candidate setting identifiers, and each of the candidate setting identifiers is used to determine one of the candidate RBG granularities.

[0085]

Table 4

[0086] Similarly, when the number range of the second RBs is the number range to which the average value of the number of RBs occupied by the BWPs set in a plurality of cells belongs, illustratively, the number range of the second RBs in Table 4 (represented by the average BWP size) may be the same as the value range corresponding to the BWP size in Table 2. Correspondingly, the RBG granularity corresponding to Setting 1 and Setting 2 in Table 4 may also be the same as the RBG granularity corresponding to Setting 1 and Setting 2 in Table 2.

[0087] The terminal can determine the RBG granularity P of the first cell through Table 3 or Table 4 according to the number range of the second RBs and the candidate configuration identifier indicated by the base station through RRC signaling.

[0088] In the above embodiments, the RBG granularity of the first cell can be determined by using any of the above methods. Then, based on the RBG granularity of the first cell, the resource allocation type of the first cell, and the indicated value of the FDRA field, the frequency domain resources for data transmission of the first cell can be determined, which is simple to implement and highly available.

[0089] Correspondingly, regarding step 304 above, the process of determining the frequency domain resources for data transmission of the first cell based on the RBG granularity of the first cell, the resource allocation type of the first cell, and the indicated value of the FDRA field includes the following steps.

[0090] First, the terminal determines the RB range occupied by each RBG of the BWP set in the first cell based on the BWP size of the first cell, that is, the number of RBs occupied by the partial bandwidth BWP set in the first cell, and the RBG granularity of the first cell determined by the above method.

[0091] For the first cell i, after determining the RBG granularity P, the corresponding number of RBGs and each RBG size are determined based on the relevant mechanism.

[0092] The specific formula is It is JPEG2025522626000006.jpg with a value of 11124. Here, the size of the first RBG is JPEG2025522626000007.jpg with a value of 10140, JPEG2025522626000008.jpg with a value of 9115. When it is JPEG2025522626000009.jpg with a value of 9114, the size of the last RBG is JPEG2025522626000010.jpg with a value of 8140. Otherwise, the size of the last RBG is P,

[0093] The sizes of all other RBGs are all P. Here, JPEG2025522626000011.jpg with values of 9116 are respectively the number of consecutive RBs in the BWP and the BWP start RB position set for the first cell i.

[0094] For example, if the RBG granularity is 4 and the BWP size is 25, based on the above solution, there are 7 RBGs in the first cell. RBG#0 contains RBs #0 - #3, RBG#1 contains RBs #4 - #7, RBG#2 contains RBs #8 - #11, RBG#3 contains RBs #12 - #15, RBG#4 contains RBs #16 - #19, RBG#5 contains RBs #20 - #23, and RBG#6 contains only RB #24.

[0095] Furthermore, the terminal determines the frequency domain resources for data transmission of the first cell based on the resource allocation type of the first cell and the indicated value of the FDRA field.

[0096] Here, when the resource allocation type of the first cell is type0, the FDRA field indicates, through a bitmap, the frequency domain resources for data transmission of the first cell, and the terminal can determine the RBG index for data transmission of the first cell based on the indicated value of the FDRA field.

[0097] Here, when the resource allocation type of the first cell is type1, the FDRA field can indicate the frequency domain resources of the first cell through a Resource Indication Value (RIV), where the RIV is associated with the starting RBG index and the RBG consecutive number of data transmission. The terminal determines the starting RBG index and the RBG consecutive number for data transmission of the first cell based on the indicated value of the FDRA field.

[0098] Here, when the resource allocation type of the first cell is dynamic, the terminal can determine that the resource allocation type of the first cell is type0 or type1 based on the MSB of the FDRA field, and further determine the frequency domain resources for data transmission of the first cell by the above method.

[0099] In the above embodiments, based on the above first correspondence or second correspondence, the RBG granularity of the first cell can be determined. In the first correspondence, the number range of the first RBs corresponds to three or more candidate setting identifiers. When the setting identifier is larger, the corresponding RBG granularity becomes larger, thereby increasing the number of RBs included in each RBG. When the frequency domain resources for cell data transmission are indicated through the FDRA field, the bits included in the FDRA field can be effectively reduced. In the second correspondence, the number range of the second RBs for determining the RBG granularity is the number range to which the sum or average value of the number of RBs occupied by the BWPs set for the plurality of cells belongs. Similarly, the bits included in the FDRA field can be reduced, ensuring the flexibility scheduled by the DCI, reducing the DCI bit overhead, effectively avoiding the problem of reduced DCI transmission efficiency, and having high availability.

[0100] In some alternative embodiments, in a scenario where the DCI schedules a plurality of cells, it can be restricted such that the resource allocation types of the plurality of cells scheduled by the DCI are the same. Based on this, the FDRA field can be indicated in the following manner.

[0101] First method: The FDRA field uses a combined indication method. In a possible implementation form, the resource allocation types of the plurality of cells are all of the first type, and the RBG index for data transmission of the plurality of cells is determined based on a first reference cell. Here, the first type indicates the frequency domain resources for cell data transmission by a bitmap, that is, the first type is type0. The first reference cell is a cell different from the first cell among the plurality of cells.

[0102] The first reference cell may be indicated by the base station through signaling, or the first reference cell may be determined through a protocol agreement. In one possible implementation, among the plurality of cells, the cell that receives DCI may be used as this first reference cell.

[0103] In another possible implementation, among the plurality of cells, the cell with the largest number of RBs occupied by the configured BWP may be used as the first reference cell.

[0104] In another possible implementation, among the plurality of cells, the cell with the smallest number of RBs occupied by the configured BWP may be used as the first reference cell.

[0105] In another possible implementation, among the plurality of cells, the cell with the largest corresponding cell index number may be used as the first reference cell.

[0106] In another possible implementation, among the plurality of cells, the cell with the smallest corresponding cell index number may be used as the first reference cell.

[0107] The above is only an exemplary description, and any method for determining the first reference cell from among the plurality of cells in actual applications falls within the protection scope of the present disclosure.

[0108] Correspondingly, the FDRA field is used to indicate the RBG index for data transmission of the first reference cell.

[0109] In this case, the terminal can determine the frequency domain resources for data transmission of the first cell based on the resource allocation type of the first cell and the indicated value of the frequency domain resource allocation FDRA field in the DCI.

[0110] Specifically, when the RBG index value indicated by the FDRA field is less than or equal to the maximum RBG index value determined by the BWP configured for the first cell, the terminal may determine that the RBG index for data transmission of the first cell is the same as that of the first reference cell.

[0111] If the RBG index value indicated by the FDRA field is greater than the maximum RBG index value determined by the BWP set in the first cell, the terminal may determine the RBG index of the first cell as the maximum RBG index value of the first cell. For example, if the bitmap indicated by the FDRA field is 1001011, the length is 6, and the maximum length of the RBG bitmap of the first cell is 7, the RBG index for data transmission of the first cell is the same as that of the reference cell and is determined to be all RBG#0, RBG#3, RBG#5, RBG#6.

[0112] As another example, if the bitmap indicated by the FDRA field is 1001011, the length is 6, the length of the RBG bitmap of the first cell is 5, specifically 100101, the RBG index for data transmission of the first cell is determined to be RBG#0, RBG#3, RBG#5.

[0113] In another possible implementation, the resource allocation type of the plurality of cells is the second type, and the frequency domain resources for data transmission of the plurality of cells are determined based on the first reference cell.

[0114] Here, the second type refers to type1, and the FDRA field is used to indicate the RIV of the first reference cell.

[0115] In the embodiments of the present disclosure, the RIV of the first cell is determined based on the RIV of the first reference cell.

[0116] Specifically, if the RIV of the first reference cell is less than or equal to the maximum RIV determined by the BWP set in the first cell, it is determined that the RIV of the first cell is equal to the RIV of the first reference cell, and according to the RIV of the first cell, the start RBG index and the number of consecutive RBGs for data transmission of the first cell can be determined according to the related art.

[0117] When the RIV of the first reference cell is greater than the maximum RIV determined by the BWP set for the first cell, the RIV of the first cell can be determined to be equal to a preset RIV. Specifically, the preset RIV may be the maximum RIV of the first cell. Furthermore, the terminal can determine the start RBG index and the number of consecutive RBGs for data transmission of the first cell according to the RIV of the first cell and according to the related art.

[0118] In another possible implementation, the resource allocation types of multiple cells are of the third type, i.e., the dynamic type. The terminal can first determine that the resource allocation type is type0 or type1 based on the MSB of the FDRA field, and further can determine the frequency domain resources for data transmission of the first cell by the above method.

[0119] The second method: The FDRA field uses a method of individual indication. In the embodiments of the present disclosure, the DCI includes a plurality of FDRA fields, and the number of the plurality of FDRA fields is equal to the number of cells of the plurality of cells. For example, when the number of cells of a plurality of cells scheduled by DCI is n, the DCI includes n FDRA fields, where n is a positive integer greater than 1.

[0120] In a possible implementation, the resource allocation types of multiple cells are all of the first type. The first type indicates the frequency domain resources for data transmission of the cell by a bitmap, that is, the first type is type0. The i-th FDRA field in the DCI is used to indicate the RBG index for data transmission of the i-th cell scheduled among the plurality of cells, and i is a positive integer less than or equal to the number of cells.

[0121] The terminal can determine an FDRA field corresponding to a first cell in DCI, and determine an RBG index for data transmission of the first cell based on an indication value of the FDRA field corresponding to the first cell. Note that the RBG index indicated by each FDRA field may be one or more, and the present disclosure does not limit this.

[0122] In another possible implementation, the resource allocation types of a plurality of cells are all type0, and the i-th FDRA field in the DCI is used to indicate an RBG index for data transmission of the i-th cell scheduled among the plurality of cells, where i is a positive integer less than or equal to the number of cells.

[0123] Also, the designated bit in each FDRA field is used to indicate a set to which the RBG index value available for data transmission of a cell belongs.

[0124] In one possible implementation, the RBG index values available for data transmission of a cell are only odd numbers or only even numbers.

[0125] The terminal can determine whether the RBG index value available for data transmission of the corresponding scheduled cell is odd or even through the designated bit of each FDRA field. For example, when the bit value of the designated bit in the FDRA field corresponding to the first cell is 1, the terminal can determine that the RBG index value available for data transmission of the first cell is odd. When the bit value of the designated bit in the FDRA field corresponding to the first cell is 0, the terminal can determine that the RBG index value available for data transmission of the first cell is even. The reverse is also true.

[0126] By reducing the RBG index values available for data transmission of the scheduled cells, the bit values of the FDRA fields can be further reduced.

[0127] In an embodiment of the present disclosure, when the MSB in the FDRA field is not occupied, that is, when the terminal determines that the resource allocation type of a plurality of cells is type0 through the RRC signaling transmitted by the base station, the designated bit is the MSB. That is, the MSB of each FDRA field in the DCI is used to indicate whether the RBG index value available for data transmission of the cell is even or odd.

[0128] When the MSB in the FDRA field is occupied, that is, when the terminal determines that the resource allocation type of a plurality of cells is dynamic through the RRC signaling transmitted by the base station, the terminal determines that the resource allocation type of the first cell is type0 according to the MSB in the FDRA field corresponding to the first cell. At this time, the MSB is occupied, and the designated bit may be 1 bit located after and adjacent to the MSB, or the designated bit may be the least significant bit LSB.

[0129] In another possible implementation, the resource allocation types of a plurality of cells are all of the second type, that is, type1, and the i-th FDRA field in the DCI is used to indicate the RIV for data transmission of the cell scheduled at the i-th position among the plurality of cells, where i is a positive integer less than or equal to the number of cells.

[0130] The terminal determines the FDRA field corresponding to the first cell in the DCI, determines the RIV of the first cell based on the indication value of the FDRA field corresponding to the first cell, and thereby can determine the start RBG index and the number of consecutive RBGs for data transmission of the first cell.

[0131] In another possible implementation, the resource allocation types of multiple cells are of the third type, i.e., dynamic. The MSB of this DCI FDRA field is used to indicate that the resource allocation types of multiple cells are all type0 or type1.

[0132] After determining the resource allocation types of multiple cells, the terminal determines the frequency domain resources for data transmission of the first cell by the above method.

[0133] In the above embodiment, when the DCI schedules data transmission of multiple cells, it can be restricted so that the resource allocation types of multiple cells are the same. Furthermore, the frequency domain resources for data transmission of the first cell can be determined by the above method, ensuring the flexibility scheduled by the DCI, reducing the DCI bit overhead, effectively avoiding the problem of reduced DCI transmission efficiency, and having high availability.

[0134] In some optional embodiments, in a scenario where the DCI schedules multiple cells, the resource allocation types of the multiple scheduled cells are not necessarily the same. At this time, the FDRA field can use a method of partial combination for indication.

[0135] The FDRA field includes a plurality of bit intervals, and the number of the plurality of bit intervals is equal to the number of resource allocation types. For example, when the number of resource allocation types is m, the number of bit intervals is also m.

[0136] In one possible implementation, the number of resource allocation types is 4, including type0, type1, dynamic+type0, and dynamic+type1. Note that dynamic+type0 means that the base station indicates through RRC signaling that the resource allocation type of the cell is dynamic, and further indicates through the MSB in the FDRA field that the resource allocation type of this cell is type0. Dynamic+type1 means that the base station indicates through RRC signaling that the resource allocation type of the cell is dynamic, and further indicates through the MSB in the FDRA field that the resource allocation type of this cell is type1.

[0137] In an embodiment of the present disclosure, the j-th bit section of the DCI is used to indicate the frequency domain resource for data transmission of the cell corresponding to the j-th resource allocation type, and j is a positive integer less than or equal to the number of the resource allocation types.

[0138] The terminal can determine the first bit section of the FDRA field corresponding to the first cell based on the resource allocation type of the first cell. Further, based on the indication value of the first bit section, the frequency domain resource for data transmission of the first cell can be determined.

[0139] Optionally, when at least one cell has the same resource allocation method as the first cell, the first bit section is further used to indicate the frequency domain resource for data transmission of the second reference cell, and the frequency domain resource for data transmission of the first cell is determined based on the second reference cell. The second reference cell is a cell different from the first cell among the cells having the same resource allocation type as the resource allocation type corresponding to the first bit section.

[0140] The method by which the terminal determines the frequency domain resources for the data transmission of the first cell is the same as the method in which the above FDRA field indicates the frequency domain resources for the data transmission of the reference cell and the terminal determines the frequency domain resources of the first cell based on the frequency domain resources corresponding to the reference cell, so it will not be described again here.

[0141] In the above embodiments, it is possible to ensure the flexibility scheduled by DCI, reduce the DCI bit overhead, effectively avoid the problem of reduced DCI transmission efficiency, and have high availability.

[0142] Next, the multi-carrier scheduling method provided by the present disclosure from the base station side will be described.

[0143] The embodiments of the present disclosure provide a multi-carrier scheduling method. Referring to FIG. 4, FIG. 4 is a flowchart of a multi-carrier scheduling method according to an embodiment. This method is executed by a base station and can include the following steps.

[0144] In step 401, determine the frequency domain resources of each cell among a plurality of cells that need to be scheduled by downlink control information DCI, where the DCI is used to schedule the data transmission of the plurality of cells.

[0145] In the embodiments of the present disclosure, the DCI is used to schedule the data transmission of a plurality of cells and includes, but is not limited to, scheduling the PDSCH of a plurality of cells and / or the PUSCH of a plurality of cells. Here, each cell corresponds to one PDSCH and / or each cell corresponds to one PUSCH.

[0146] In step 402, determine the resource allocation type for the data transmission of each cell.

[0147] In an embodiment of the present disclosure, the resource allocation type of each cell may be determined through RRC signaling transmitted by a base station, and the resource allocation type of the first cell may be type0, type1, or dynamic.

[0148] In step 403, at least based on the resource allocation type of each cell and the frequency domain resource corresponding to each cell, determine the bit value of the frequency domain resource allocation FDRA field in the DCI. In step 404, transmit the DCI to the terminal.

[0149] In the above embodiment, while ensuring the flexibility scheduled by the DCI, reducing the DCI bit overhead, effectively avoiding the problem of reduced DCI transmission efficiency, it has high availability.

[0150] In some alternative embodiments, referring to FIG. 5, FIG. 5 is a flowchart of a multi-carrier scheduling method according to an embodiment, and this method is executed by a base station and can include the following steps.

[0151] In step 501, determine the frequency domain resource of each cell among a plurality of cells that need to be scheduled by downlink control information DCI, and the DCI is used to schedule the data transmission of the plurality of cells.

[0152] In an embodiment of the present disclosure, the DCI is used to schedule the data transmission of a plurality of cells, and includes but is not limited to scheduling the PDSCH of a plurality of cells and / or the PUSCH of a plurality of cells. Here, each cell corresponds to one PDSCH, and / or each cell corresponds to one PUSCH.

[0153] In step 502, determine the resource allocation type for the data transmission of each cell.

[0154] In an embodiment of the present disclosure, the resource allocation type of each cell may be determined through RRC signaling transmitted by a base station, and the resource allocation type of the first cell may be type0, type1, or dynamic.

[0155] In step 503, determine the resource block group (RBG) granularity of each cell. In an embodiment of the present disclosure, according to the BWP size and the configuration identifier indicated by the RRC signaling transmitted by the base station, the RBG granularity P of each cell can be determined. In an embodiment of the present disclosure, the execution order of step 502 and step 503 is not limited.

[0156] In step 504, based on the resource allocation type of each cell, the RBG granularity of each cell, and the frequency domain resources corresponding to each cell, determine the bit value of the FDRA field.

[0157] In step 505, transmit the DCI to the terminal. In the above embodiment, by combining the resource allocation type of each cell, the RBG granularity of each cell, and the frequency domain resources corresponding to each cell, the bit value of the FDRA field can be determined. While ensuring the flexibility scheduled by the DCI, reducing the DCI bit overhead, effectively avoiding the problem of reduced DCI transmission efficiency, it has high availability.

[0158] Regarding the above step 503, in a possible implementation form, the RBG granularity of the first cell is determined based on the first correspondence relationship among the number range of the first RBs, the candidate configuration identifier, and the candidate RBG granularities. Here, the first cell is any one of a plurality of cells.

[0159] Here, the number range of the first RBs is the number range to which the number of RBs occupied by the partial bandwidth part (BWP) set in the first cell belongs. In the first correspondence relationship, the number range of the first RBs corresponds to three or more candidate configuration identifiers, and each of the candidate configuration identifiers corresponds to one of the candidate resource block group (RBG) granularities.

[0160] That is, the present disclosure can extend the correspondence relationship shown in Table 1. For example, as shown in Table 2 above, at least the configuration3 setting can be added.

[0161] The terminal determines the number range of the first RBs based on the number of RBs occupied by the BWP set in the first cell, and further jointly determines the RBG granularity P of the first cell through the correspondence relationship in Table 2 according to the number range of the first RBs and the candidate configuration identifier indicated by the base station through RRC signaling.

[0162] In another possible implementation, the RBG granularities of multiple cells are the same. Based on this, the RBG granularities of the multiple cells are determined based on a second correspondence relationship among the number range of the second RBs, the candidate configuration identifier, and the candidate RBG granularity.

[0163] Here, the number range of the second RBs is the number range to which the sum or average value of the number of RBs occupied by the BWP set in the multiple cells belongs. For example, assuming that the number of RBs occupied by the configured BWPs of three cells are 25, 37, and 76 respectively, the average value is 46, which belongs to the RB number range 2, and the candidate configuration identifier is 1, then based on the second correspondence relationship, the RBG granularities of the three cells are the same and can be determined to be equal to P 12 If it is assumed that the value of P 12 is 4, then the RBG granularities of these three cells will all be 4.

[0164] Optionally, in the second correspondence relationship, for example, as shown in Table 3 above, the number range of the second RB corresponds to three or more candidate configuration identifiers, and each of the candidate configuration identifiers is used to determine one of the candidate RBG granularities.

[0165] In addition, when the number range of the second RB is the number range to which the average value of the number of RBs occupied by the BWPs set in a plurality of cells belongs, exemplarily, the number range of the second RB in Table 3 (represented by the average BWP size) may be the same as the value range corresponding to the BWP size in Table 2. Correspondingly, the RBG granularities corresponding to Setting 1, Setting 2, Setting 3, etc. in Table 3 may also be the same as the RBG granularities corresponding to Setting 1, Setting 2, Setting 3, etc. in Table 2.

[0166] Optionally, in the second correspondence relationship, for example, as shown in Table 4 above, the number range of the second RB corresponds to two or more candidate configuration identifiers, and each of the candidate configuration identifiers is used to determine one of the candidate RBG granularities.

[0167] The terminal can determine the RBG granularity P of the first cell through Table 3 or Table 4 above according to the number range of the second RB and the candidate configuration identifier indicated by the base station through RRC signaling.

[0168] Similarly, when the number range of the second RB is the number range to which the average value of the number of RBs occupied by the BWPs set in a plurality of cells belongs, exemplarily, the number range of the second RB in Table 4 (represented by the average BWP size) may be the same as the value range corresponding to the BWP size in Table 2. Correspondingly, the RBG granularities corresponding to Setting 1 and Setting 2 in Table 4 may also be the same as the RBG granularities corresponding to Setting 1 and Setting 2 in Table 2.

[0169] In the above embodiments, the RBG granularity of the first cell can be determined using any of the above methods, and then, based on the RBG granularity of the first cell, the resource allocation type of the first cell, and the frequency domain resources for data transmission of the first cell, the bit value of the FDRA field can be jointly determined, which is simple to implement and highly available.

[0170] Correspondingly, regarding step 504 above, the base station can determine the bit value of the FDRA field based on the RBG granularity of the first cell, the resource allocation type of the first cell, and the frequency domain resources for data transmission of the first cell. At this time, the base station can expand the FDRA field in the DCI to individually indicate the frequency domain resources corresponding to each cell.

[0171] Here, when the resource allocation type of the first cell is type0, the bit section corresponding to the first cell in the FDRA field can jointly determine the bit value of this bit section based on the RBG granularity of the first cell and the RBG index for data transmission of the first cell. For the first cell i, after determining the RBG granularity P, the corresponding number of RBGs and each RBG size are determined based on the relevant mechanism.

[0172] The specific formula is JPEG2025522626000012.jpg10136. Here, the size of the first RBG is JPEG2025522626000013.jpg13168, JPEG2025522626000014.jpg9115. When JPEG2025522626000015.jpg9116, the size of the last RBG is JPEG2025522626000016.jpg9116, In other cases, the size of the last RBG is P, The sizes of all other RBGs are all P. Here, JPEG2025522626000017.jpg9115 are, respectively, the number of consecutive RBs of the BWP set in the first cell i and the BWP start RB position.

[0173] When the resource allocation type of the first cell is type1, the bit section corresponding to the first cell in the FDRA field determines the RIV of the first cell based on the RBG granularity of the first cell, the start RBG index value for data transmission of the first cell, and the number of consecutive RBGs. Furthermore, based on the RIV of the first cell, the bit value of this bit section can be determined.

[0174] When the resource allocation type of the first cell is dynamic, the base station can indicate through the MSB in the FDRA field that the resource allocation type of the first cell is type0 or type1 according to the dynamically determined resource allocation type of the first cell. Since the bit values of other bits can be determined by the above method, they will not be described again here.

[0175] In the above embodiments, the base station can determine the bit value of the FDRA field based on the RBG granularity of the first cell, the resource allocation type of the first cell, and the frequency domain resource for data transmission of the first cell. Here, the RBG granularity of the first cell is determined based on the first correspondence relationship or the second correspondence relationship. While ensuring the flexibility scheduled by the DCI, compared with the case where the DCI schedules multiple cells, since the data transmission of each cell is performed based on the RB granularity, the DCI bit overhead is reduced, the problem of reduced DCI transmission efficiency is effectively avoided, and it has high availability.

[0176] In some optional embodiments, in a scenario where the DCI schedules a plurality of cells, it can be restricted such that the resource allocation types of the plurality of cells scheduled by the DCI are the same. Based on this, the FDRA field can be indicated in the following manner.

[0177] First method: The FDRA field uses a combined indication method. In one possible implementation, the resource allocation types of the plurality of cells are all of the first type, and the RBG index for data transmission of the plurality of cells is determined based on a first reference cell.

[0178] Here, the first type indicates the frequency domain resources for cell data transmission by means of a bitmap, that is, the first type is type0. The first reference cell is a cell different from the first cell among the plurality of cells.

[0179] The first reference cell may be indicated by the base station through signaling, or the first reference cell may be determined through a protocol agreement.

[0180] In one possible implementation, among the plurality of cells, the cell that receives the DCI may be used as this first reference cell.

[0181] In another possible implementation, among the plurality of cells, the cell with the largest number of RBs occupied by the configured BWP may be used as the first reference cell. In another possible implementation, among the plurality of cells, the cell with the smallest number of RBs occupied by the configured BWP may be used as the first reference cell. In another possible implementation, among the plurality of cells, the cell with the largest corresponding cell index number may be used as the first reference cell. In another possible implementation, among the plurality of cells, the cell with the smallest corresponding cell index number may be used as the first reference cell.

[0182] The above is only an illustrative description, and any method for determining the first reference cell from among a plurality of cells in actual applications falls within the protection scope of the present disclosure. Correspondingly, the FDRA field is used to indicate the RBG index for data transmission of the first reference cell.

[0183] The base station can determine the frequency domain resources for data transmission of the first cell based on the resource allocation type of the first cell and the RBG index for data transmission of the first reference cell.

[0184] Specifically, when the RBG index value indicated by the FDRA field is less than or equal to the maximum RBG index value determined by the BWP set for the first cell, the terminal may determine that the RBG index for data transmission of the first cell is the same as that of the first reference cell.

[0185] When the RBG index value indicated by the FDRA field is greater than the maximum RBG index value determined by the BWP set for the first cell, the terminal may determine the RBG index of the first cell as the maximum RBG index value of the first cell. In this case, the terminal can determine the bit value of the frequency domain resource allocation FDRA field in the DCI based on the RBG index for data transmission of the first reference cell.

[0186] In another possible implementation, the resource allocation type of the plurality of cells is the second type, and the frequency domain resources for data transmission of the plurality of cells are determined based on the first reference cell.

[0187] Here, the second type refers to type1, and the FDRA field is used to indicate the RIV of the first reference cell.

[0188] In an embodiment of the present disclosure, the RIV of the first cell is determined based on the RIV of the first reference cell. Specifically, when the RIV of the first reference cell is less than or equal to the maximum RIV determined by the BWP set for the first cell, it is determined that the RIV of the first cell is equal to the RIV of the first reference cell. According to the RIV of the first cell, the starting RBG index and the number of consecutive RBGs for data transmission of the first cell can be determined according to the related art.

[0189] When the RIV of the first reference cell is greater than the maximum RIV determined by the BWP set for the first cell, it can be determined that the RIV of the first cell is equal to a preset RIV. Specifically, the preset RIV may be the maximum RIV of the first cell.

[0190] In this case, the terminal can determine the bit value of the frequency domain resource allocation FDRA field in the DCI based on the RIV of the first reference cell.

[0191] In another possible implementation, the resource allocation types of multiple cells are of the third type, that is, the dynamic type. The terminal first determines whether the resource allocation type is type0 or type1 based on the MSB of the FDRA field, and further can determine the bit value of the FDRA field by the above method.

[0192] The second method: The FDRA field uses the method of individual indication. In an embodiment of the present disclosure, the DCI includes a plurality of FDRA fields, and the number of the plurality of FDRA fields is equal to the number of cells of the plurality of cells.

[0193] In one possible implementation, the resource allocation types of a plurality of cells are all of the first type. The first type indicates, by means of a bitmap, the frequency domain resources for data transmission of a cell, that is, the first type is type0. The i-th FDRA field in the DCI is used to indicate the RBG index for data transmission of the i-th cell scheduled among the plurality of cells, where i is a positive integer less than or equal to the number of cells.

[0194] The base station can determine the bit value of the i-th FDRA field in the DCI based on the RBG index for data transmission of the i-th cell scheduled among the plurality of cells. Note that the RBG index indicated by each FDRA field may be one or more, and the present disclosure does not limit this.

[0195] In another possible implementation, the resource allocation types of a plurality of cells are all type0. The i-th FDRA field in the DCI is used to indicate the RBG index for data transmission of the i-th cell scheduled among the plurality of cells, where i is a positive integer less than or equal to the number of cells.

[0196] Also, the designated bit in each FDRA field is used to indicate the set to which the RBG index value available for data transmission of a cell belongs. In one possible implementation, the set to which the RBG index value available for data transmission of a cell belongs consists of only odd numbers or only even numbers. The base station determines the bit value of the designated bit of each FDRA field according to whether the RBG index value available for data transmission of the scheduled cell is odd or even.

[0197] For example, if the base station determines that the RBG index value available for data transmission in the first cell is odd, the base station can determine that the bit value of the designated bit in the FDRA field corresponding to the first cell is 1. If it is determined that the RBG index value available for data transmission in the first cell is even, the base station can determine that the bit value of the designated bit in the FDRA field corresponding to the first cell is 0. The reverse is also true.

[0198] By reducing the RBG index value available for data transmission of the scheduled cell, the bit value of the FDRA field can be further reduced. In an embodiment of the present disclosure, when the MSB in the FDRA field is not occupied, that is, when the terminal determines that the resource allocation type of a plurality of cells is type0 through RRC signaling transmitted by the base station, the designated bit is the MSB. That is, the MSB of each FDRA field in the DCI is used to indicate whether the RBG index value available for data transmission of the cell is even or odd.

[0199] When the MSB in the FDRA field is occupied, that is, when the terminal determines that the resource allocation type of a plurality of cells is dynamic through RRC signaling transmitted by the base station, the base station determines the MSB in the FDRA field corresponding to the first cell according to the fact that the resource allocation type of the first cell is type0. At this time, the MSB is occupied, and the designated bit may be the 1-bit adjacent to and following the MSB, or the designated bit may be the least significant bit LSB.

[0200] In another possible implementation, the resource allocation types of a plurality of cells are all of the second type, i.e., type1, and the i-th FDRA field in the DCI is used to indicate the RIV for data transmission of the i-th cell scheduled among the plurality of cells, where i is a positive integer less than or equal to the number of cells.

[0201] The base station can determine the FDRA field corresponding to the first cell in the DCI and determine the bit value of the FDRA field corresponding to the first cell based on the RIV of the first cell.

[0202] In another possible implementation, the resource allocation types of a plurality of cells are of the third type, i.e., dynamic. The MSB of this DCI FDRA field is used to indicate that the resource allocation types of the plurality of cells are all type0 or type1. Since the bit values of the other bits are also determined in the same way as the above method, they will not be described again here.

[0203] In the above embodiments, when the DCI schedules data transmission of a plurality of cells, it can be restricted so that the resource allocation types of the plurality of cells are the same. Furthermore, the bit value of the FDRA field can be determined by the above method, ensuring the flexibility scheduled by the DCI, reducing the DCI bit overhead, effectively avoiding the problem of reduced DCI transmission efficiency, and having high availability.

[0204] In some alternative embodiments, in a scenario where the DCI schedules a plurality of cells, the resource allocation types of the plurality of scheduled cells are not necessarily the same. At this time, the FDRA field can use a method of partial combination and indication.

[0205] The FDRA field includes a plurality of bit intervals, and the number of the plurality of bit intervals is equal to the number of resource allocation types. For example, when the number of resource allocation types is m, the number of bit intervals is also m.

[0206] In one possible implementation, the number of resource allocation types is 4, including type0, type1, dynamic+type0, and dynamic+type1. Note that dynamic+type0 means that the base station indicates through RRC signaling that the resource allocation type of the cell is dynamic, and further indicates through the MSB in the FDRA field that the resource allocation type of this cell is type0. Dynamic+type1 means that the base station indicates through RRC signaling that the resource allocation type of the cell is dynamic, and further indicates through the MSB in the FDRA field that the resource allocation type of this cell is type1.

[0207] In an embodiment of the present disclosure, the j-th bit interval of the DCI is used to indicate the frequency domain resources for data transmission of the cell corresponding to the j-th resource allocation type, and j is a positive integer less than or equal to the number of the resource allocation types.

[0208] The base station can determine the resource allocation type of the first cell, and further can determine the first bit interval of the FDRA field corresponding to the first cell. Also, according to the frequency domain resources for data transmission of the first cell, the bit value of the first bit interval can be determined.

[0209] Optionally, when at least one cell has the same resource allocation method as the first cell, the first bit interval is further used to indicate the frequency domain resources for data transmission of the second reference cell, the frequency domain resources for data transmission of the first cell are determined based on the second reference cell, and the second reference cell is a cell different from the first cell among the cells having the same resource allocation type as the resource allocation type corresponding to the first bit interval.

[0210] Even in the above embodiments, it is possible to ensure the flexibility scheduled by DCI, reduce the DCI bit overhead, effectively avoid the problem of reduced DCI transmission efficiency, and have high availability.

[0211] The above method will be further described with more examples below.

[0212] Example 1 Assume that the terminal is a terminal with a version after Rel-18, the terminal receives DCI for multi-cell scheduling, and based on the instruction information corresponding to the DCI, receives the PDSCH of multiple cells or transmits the PUSCH of multiple cells.

[0213] In this embodiment, considering that the frequency domain resource information of different scheduled cells indicated by the FDRA field of DCI (multi-cell DCI, mcDCI) used for scheduling multiple cells is based on the type0, type1, or dynamic resource allocation method, the number of RBs included in the RBG corresponding to the mcDCI is defined as P, so as to realize the indication of the PDSCH or PUSCH frequency domain resource information for multiple scheduled cells by the mcDCI. It should be noted that based on the RBG, the mcDCI can realize the scheduling of the FDRA field in the type1 method with type0 and RBG as the granularity.

[0214] In one possible implementation, the RBGs corresponding to different scheduled cells are not exactly the same. Add the configuration3 setting to configuration1 and configuration2 defined in Table 1. The RBG granularity P corresponding to the configuration3 is greater than or equal to the granularity corresponding to configuration2. For the scheduled cell i, the terminal determines P based on the BWPsize set for the scheduled cell i and the configuration option indicated by the signaling, where the configuration option is indicated by the signaling set for the scheduled cell i, such as RRC signaling, and the configuration may be set by the cell that receives the mcDCI. One possible implementation among them is as shown in Table 5.

[0215]

Table 5

[0216] It should be noted that when configured as configuration3 under the condition that the BWPsize set for the scheduled cell i is greater than 72, the number of RBs occupied by the corresponding mcDCI RBG may be equal to 32 or may be equal to 16.

[0217] In one possible implementation, the RBG granularities corresponding to different scheduled cells are the same. For example, all are P. The P corresponds to the BWPsize and the configured configuration set for all scheduled cells simultaneously scheduled by the mcDCI. One possible implementation among them is as shown in Table 6.

[0218]

Table 6

[0219] Here, the BWP size shown in Table 6 is equal to the average value of the BWP sizes set for all the scheduled cells simultaneously scheduled by the mcDCI. In another possible implementation, it is also possible to define that the sum of the BWP sizes set for all the scheduled cells simultaneously scheduled by the mcDCI is associated with the P. The specific implementation is associated with Table 6, and the present invention will not elaborate on this in detail. Add the configuration3 setting to configuration1 and configuration2 defined in Table 1. The configuration option may be set by the cell receiving the mcDCI. The configuration option may also be set individually by each scheduled cell. For example, it may be set by RRC signaling. In this scenario, it is necessary to limit so that the configuration options set for each cell scheduled simultaneously are the same. If the configurations set for each scheduled cell are different, the terminal determines the RBG granularity based on the configuration set by the cell receiving the mcDCI and Table 6, or the terminal determines this as an error case and does not process it further.

[0220] It should be noted that when it is set as configuration3 under the condition that the average value of the BWP sizes set for all the cells scheduled simultaneously is greater than 72, the number of RBs occupied by the corresponding mcDCI RBG may be equal to 32 or may be equal to 16. In one possible implementation, the RBG granularities corresponding to different scheduled cells are the same. For example, they are all P. The P corresponds to the BWP size and the set configuration set for all the scheduled cells simultaneously scheduled by the mcDCI. One possible implementation among them is as shown in Table 7.

[0221]

Table 7

[0222] Here, the BWP size shown in Table 7 is equal to the average value of the BWP sizes set for all scheduled cells simultaneously scheduled by the mcDCI. In another possible implementation, it can also be defined such that the sum of the BWP sizes set for all scheduled cells simultaneously scheduled by the mcDCI is associated with the P. The specific implementation is associated with Table 1, and the present invention will not elaborate on this in detail.

[0223] The aforementioned configuration1 and configuration2 are defined based on Table 1. The configuration option may be set by the cell receiving the mcDCI. The configuration option may also be set individually by each scheduled cell. For example, it may be set by RRC signaling. In this scenario, it is necessary to limit such that the configuration options set for each cell scheduled simultaneously are the same. If the configurations set for each scheduled cell are different, the terminal determines the RBG granularity based on the configuration set by the cell receiving the mcDCI and Table 7, or the terminal determines this as an error case and does not process it further.

[0224] Based on the above implementation, for the scheduled cell i, after determining the RBG granularity P, the corresponding number of RBGs and each RBG size are determined based on the relevant mechanism. The specific formula is JPEG2025522626000021.jpg10120. Here, the size of the first RBG is JPEG2025522626000022.jpg14160, It is JPEG2025522626000023.jpg10136. When it is JPEG2025522626000024.jpg10136, the size of the last RBG is When it is JPEG2025522626000025.jpg9128, and in other cases, the size of the last RBG is P, The sizes of all other RBGs are all P. Here, JPEG2025522626000026.jpg10124 are respectively the number of consecutive RBs of the BWP set in the scheduled cell i and the BWP start RB position.

[0225] For the scheduled cell i, after determining the RBG granularity P, the terminal can determine the frequency domain information for data transmission in the scheduled cell i based on the FDRA resource setting type and based on the mcDCI FDRA field indication information. When the terminal is based on the type1 resource allocation type and the frequency domain resource allocation uses the RBG as the granularity, the correspondence between the RIV indicated by the FDRA field and the corresponding frequency domain information is the same as that of the existing mechanism's DCIformat1_2, and will not be described again in the present invention.

[0226] When the terminal is based on the type1 resource allocation type, whether the corresponding frequency domain resource allocation uses the RB as the granularity or the RBG as the granularity may be determined based on a predefined method. For example, when the number of simultaneously scheduled cells is less than or equal to n, the corresponding frequency domain resource allocation uses the RB as the granularity, and when the number of simultaneously scheduled cells is greater than n, the corresponding frequency domain resource allocation uses the RB as the granularity, and n is determined by a method predefined or indicated by signaling.

[0227] When the terminal is based on the type1 resource allocation type, whether the corresponding frequency domain resource allocation uses RBs or RBGs as the granularity may be determined by the method indicated by signaling. For example, as the FDRA field adds 1 bit, it indicates whether to use RBs or RBGs as the granularity.

[0228] Exemplarily, under the condition that RRC signaling indicates that the resource allocation type is type1, the MSB of the mcDCI FDRA field indicates the above information. The MSB bit value 0 corresponds to RBs as the granularity, and the MSB bit value 1 corresponds to RBGs as the granularity. Vice versa. The design rule of this embodiment defines the RBG granularity in the mc scenario, thereby effectively reducing the FDRA signaling overhead, achieving a consistent understanding of the RBG granularity by the base station and the terminal, and improving the scheduling efficiency of mcDCI.

[0229] Embodiment 2 As described in Embodiment 1, assume that the terminal is a terminal of a version after Rel-18, the terminal receives DCI for multi-cell scheduling, and based on the indication information corresponding to the DCI, receives the PDSCH of multiple cells or transmits the PUSCH of multiple cells.

[0230] This embodiment considers that the frequency domain resource information of different scheduled cells indicated by the FDRA field of multi-cell DCI may be based on type0, type1, and dynamic resource types, and designs the corresponding FDRA field indication method to realize the PDSCH / PUSCH scheduling for multi-cells by a single DCI.

[0231] In one possible implementation, the first reference cell in the mc scheduling scenario is determined, and the first reference cell is determined based on the method indicated by signaling. Exemplarily, the cell index value of the first reference cell is indicated. The reference cell may be determined based on a predefined method. Exemplarily, the cell that receives the mc DCI is determined as the first reference cell, or among all the cells scheduled simultaneously by the mc DCI, the cell corresponding to the maximum (minimum) number of RBs occupied by the configured BWP is determined as the first reference cell, or among all the cells scheduled simultaneously by the mc DCI, the cell corresponding to the minimum (maximum) cell id is determined as the first reference cell, but the present invention is not limited thereto.

[0232] In one possible implementation, for a plurality of cells scheduled by the same mc DCI, in order to reduce the DCI overhead of the mc FDRA field and reduce the complexity of the terminal's processing, the resource allocation types of the plurality of cells are restricted to be the same.

[0233] For a plurality of cells scheduled by the same mc DCI, when using the method of combining and indicating the FDRA fields corresponding to the mc DCI, the frequency domain resources corresponding to different cells are determined based on the first reference cell. The specific implementation is as follows.

[0234] The mc DCI FDRA field indicates the RIV (type1) or RBG bitmap (type0) of the reference cell. For other scheduled cells, when the indicated RIV (type1) or RBG bitmap (type0) is less than or equal to the maximum RIV value or the longest RBG bitmap (type0) determined based on the number of BWPs set in this cell, the RIV (type1) or RBG bitmap (type0) corresponding to the FDRA of other scheduled cells is the same as that of the reference cell; otherwise, the RIV (type1) or RBG bitmap (type0) corresponding to the FDRA of other scheduled cells is equal to the maximum RIV value or the longest RBG bitmap (type0) determined based on the number of BWPs set in this cell.

[0235] For multiple scheduled cells scheduled by the same mc DCI, when using the method where the FDRA field corresponding to the mc DCI individually indicates, under the condition that the resource allocation type is type0, only the RBGs corresponding to odd or even RBG indices can be scheduled.

[0236] For multiple scheduled cells scheduled by the same mc DCI, under the condition that the resource allocation type is dynamic, the MSB of the mc DCI FDRA field indicates either resource allocation type type0 or type1 for all scheduled cells.

[0237] In one possible implementation, when the terminal is based on the type0 resource allocation type, the set to which the corresponding available RBG index value belongs is an odd set or an even set.

[0238] This may be determined based on a pre-defined method or based on a method indicated by signaling. For example, the MSB of the mc DCI FDRA field indicates whether the set to which the available RBG index values belong is an odd set or an even set.

[0239] In one possible implementation, when the terminal is based on the dynamic resource allocation type and the MSB of the mc DCI FDRA field indicates that the resource allocation method for all scheduled cells is type0, the 1 bit (or LSB) after the MSB of the mc DCI FDRA field indicates whether the set to which the available RBG index values belong is an odd set or an even set. When the terminal is based on the dynamic resource allocation type and the MSB of the mc DCI FDRA field indicates that the resource allocation method for all scheduled cells is type1, the 1 bit (or LSB) after the MSB of the mc DCI FDRA field indicates whether the granularity is RB or RBG.

[0240] This embodiment restricts the resource allocation types corresponding to the FDRA fields of different scheduled cells to be the same in the mc scheduling scenario, effectively reducing the multi-cell DCI bits overhead, preventing the multi-cell DCI transmission coding rate from becoming too high and the DCI transmission performance from deteriorating, and preventing the cell scheduling performance from deteriorating.

[0241] Embodiment 3 As described in Embodiment 1, assume that the terminal is a terminal of a version after Rel-18, the terminal receives DCI for multi-cell scheduling, and based on the indication information corresponding to the DCI, receives the PDSCH of multiple cells or transmits the PUSCH of multiple cells.

[0242] In this embodiment, the frequency domain resource information of different scheduled cells indicated by the FDRA field of multi-cell DCI may be based on type0, type1, and dynamic resource types, and the frequency domain resource types of different scheduled cells are not restricted to be the same. Considering this, by designing the corresponding FDRA field indication method using a partially combined indication method, the PDSCH / PUSCH scheduling for multi-cells by a single DCI is realized.

[0243] In one possible implementation form, the FDRA field corresponding to the mc DCI is composed of different bit intervals, the number of said bit intervals is equal to 1, 2, or 3, and the number of said bit intervals is determined by the type of resource allocation type (type0, type1, dynamic) corresponding to the FDRA set for all scheduled cells simultaneously scheduled by the mc DCI. The resource allocation types corresponding to the FDRA of different scheduled cells are set by RRC signaling. Said bit intervals correspond one-to-one to different resource allocation types. For example, the corresponding bit intervals can correspond one-to-one in the order of resource allocation methods type0, type1, dynamic. As shown in FIG. 6, the same bit interval indicates the frequency domain resources of one or more scheduled cells corresponding to the same resource allocation method.

[0244] For the bit interval corresponding to type0 or type1, through the combined indication method, the frequency domain resources of one or more scheduled cells corresponding to the same resource allocation method are indicated. The number of bits occupied by the bit interval corresponding to said type0 or type1 is determined by the resource allocation type of the reference cell and the set BWP. The specific indication method is as follows.

[0245] The bits corresponding to the specific bit interval indicate the RIV or RBG of the second reference cell, and the frequency domain resources of other cells using the same resource allocation method are determined based on the second reference cell. Since the specific determination method is the same as that in Embodiment 2, the description is omitted again in the present invention.

[0246] The second reference cell may be a cell corresponding to the maximum (minimum) number of RBs occupied by the configured BWP among one or more cells corresponding to the same resource allocation method, or may be a cell corresponding to the minimum (maximum) cell id among one or more cells corresponding to the same resource allocation method scheduled simultaneously by mc DCI. The present invention does not limit this.

[0247] For the bit interval corresponding to dynamic, in a separate manner, the frequency domain resources of one or more scheduled cells corresponding to the dynamic resource allocation method are indicated. The bit interval corresponding to dynamic corresponds one-to-one to the frequency domain resources of one or more scheduled cells corresponding to the dynamic resource allocation method. The one or more scheduled cells correspond one-to-one based on the order from the smallest to the largest or from the largest to the smallest of the cell index values.

[0248] In the present embodiment, without restricting the mc scheduling scenario, in a scenario where the resource allocation types corresponding to the FDRA fields of different scheduled cells are the same, a method of partially combining and indicating is designed, which can effectively reduce the multi-cell DCI bits overhead, prevent the multi-cell DCI transmission coding rate from being too high and the DCI transmission performance from decreasing, and prevent the cell scheduling performance from decreasing.
