[0039] In one embodiment, obtaining the first parameters of the first category elements based on the second parameters of the second category elements includes: when N is greater than M, obtaining the first M first parameters of the first category elements based on the M second parameters of the second category elements, and obtaining the remaining NM first parameters of the first category elements based on a predetermined second parameter among the M second parameters of the second category elements.

[0040] In one embodiment, obtaining the first parameter of the first type of element according to the second parameter of the second type of element includes: determining the fourth parameter of the first type of element according to one of the following methods: when N is greater than M, re-dividing the N fourth parameters of the first type of element into M fourth parameters; determining the division of the fourth parameter corresponding to the first type of element according to the M value; wherein each fourth parameter corresponds to a first parameter, and the fourth parameter includes at least one of the following: a DMRS port group, a time domain resource group, a frequency domain resource group, and a transmission opportunity of the element.

[0041] In one embodiment, obtaining the first parameter of the first category element according to the second parameter of the second category element includes at least one of the following: when N is less than or equal to M, obtaining the first parameter of the first category element according to the second parameter of the second category element; when N is greater than M, obtaining the first parameter of the first category element according to the third parameter of the third category element.

[0043] In one embodiment, the mapping table includes a mapping relationship between a bit field value and an indication content in the physical downlink control information. The mapping table includes at least one of the following: a mapping relationship between a transmission control indication TCI indication field in the DCI and a TCIstate of the PDSCH; a mapping table between an SRI indication field in the DCI and an SRI of the PUSCH.

[0044] In one embodiment, the second type of elements meets the following conditions: the second type of elements includes elements that meet the predetermined characteristics among the elements whose number M of the second parameter is greater than or equal to the value N.

[0045] For example: when N and M are equal, the N first parameters of the first category elements are obtained according to the M second parameters of the second category elements. If N and M are greater than 1 at this time, it is necessary to specify the correspondence between the N first parameters and the M second parameters, so that the first parameter indexed by i is obtained according to the corresponding second parameter.

[0046] When N and M are not equal, it is necessary to determine the method for obtaining the first parameter of the first type of element. To this end, one or more of the following methods can be used:

[0047] Solution 1: The sending and receiving parties reserve (for example, the terminal and the base station reserve), when the first parameter of the first type element is obtained according to the second parameter of the second type element, N is less than or equal to M, and the first parameter of the first type element with index i is obtained according to the second parameter of the second type element with index i, where i = 0, 1, ..., M-1 or i∈{0, 1, ..., M-1}. Alternatively, a corresponding relationship between the N first parameters of the first type element and the M second parameters of the second type element is established through signaling information or a predetermined rule, and the first parameter with index i is obtained according to the second parameter with which it has a corresponding relationship.

[0048] Solution 2: When N is greater than M, the first parameter of the first type element is obtained based on the second parameter of more than one second type element. For example, based on The second parameter of the second type element obtains the first parameter of the first type element. Indicates N / M rounded up. Optionally, The second parameter of the second type of elements, first keep the second type of element index unchanged, increase the first parameter index, and then increase the second type of element index in ascending order, second parameter, and then obtain the first parameter of the first type element with index j according to the second parameter with index j, j=0,1,...,N-1. Or establish a correspondence between the first parameter and the second parameter, and obtain the first parameter with index j according to the second parameter with a corresponding relationship therewith. The above assumes that the number of second parameters of each second type element in multiple second type elements is M. Of course, this embodiment does not exclude the situation where the number of each second type element is different. For example, N=2, M=1, and the two second parameters of a first type element are obtained according to the second parameters of two second type elements, where the first parameter of the first type element with index p is obtained according to the second parameter of the second type element with index p, p=1,2. Or N=4, M=2, and four second parameters of a first-category element are obtained according to the second parameters of two second-category elements, where the indexes of the four second parameters are obtained in the order of [second parameter of second-category element with index 0, second parameter of second-category element with index 0, second parameter of second-category element with index 1, second parameter of second-category element with index 1], and then the first parameter with index j is obtained according to the second parameter with index j, where j=0, 1, 2, 3.

[0049] Optionally, the more than one second type element includes the second type elements in more than one group, or the more than one second type element belongs to the same second type element group.

[0050] Optionally, it can be obtained through signaling information or a predetermined rule whether more than one second-category elements include second-category elements in more than one group, or more than one second-category elements belong to the same second-category element group.

[0051] Optionally, the second-type element group is obtained in one of the following ways: the second-type elements included in the second-type element group are notified through signaling information; the second-type elements in a second-type element group are associated with the same group information; the time domain resources and / or frequency domain resources occupied by the second-type elements in a second-type element group meet predetermined characteristics, and the group information of the second-type elements is determined according to the group information of the control channel that schedules the second-type elements. For example, the second-type elements falling in a time unit constitute a group, and the second-type elements falling in the same frequency domain resource group constitute a group.

[0052] Solution 3: When N is greater than M, the M second parameters of the first category elements are obtained according to the M second parameters of the second category elements, and the remaining NM second parameters of the first category elements are obtained according to the third parameter, where the third parameter is obtained according to signaling information or a predetermined rule.

[0053] Optionally, there is no corresponding relationship between the third parameter and the second type of element. Or the third parameter corresponds to the third type of element, wherein the third type of element and the second type of element are different elements, or elements of different types. For example, the second type of element is a control channel, and the third type of element is a data channel.

[0054] Solution 4: When N is less than M, according to the signaling information and / or the predetermined rule, determine that the N first parameters of the first type of elements are obtained according to the N second parameters of the M second parameters of the second type of elements, for example, the N first parameters of the second type of elements are obtained according to the first N second parameters in the second information. For example, the first parameter with index j is obtained according to the second parameter with index j, j = 0, 1, ..., N-1.

[0055] Solution 5: The terminal and the base station agree that when the first parameter of the first type of element is obtained according to the second parameter of the second type of element, N is less than or equal to M min , where M min Including one of the following: the minimum number of second parameters of a second-category element; the minimum value of the total number of different second parameters in a set consisting of second parameters of all second-category elements within a period of time; the minimum value of the total number of different second parameters in a set consisting of second parameters of all second-category elements in a frequency domain bandwidth within a period of time.

[0056] Solution 6: The terminal and the base station agree that when the first parameter of the first type of element is obtained according to the second parameter of the second type of element, N is less than or equal to M max , where M max Including one of the following: the maximum number of second parameters of a second-category element; the maximum value of the total number of different second parameters in a set consisting of second parameters of all second-category elements within a period of time; the maximum value of the total number of different second parameters in a set consisting of second parameters of all second-category elements in a frequency domain bandwidth within a period of time.

[0057] Solution 7: When N is greater than M, the M first parameters of the first category elements are obtained according to the M second parameters of the second category elements, and the remaining NM first parameters of the first category elements are obtained according to a second parameter that meets the predetermined characteristics among the M second parameters. For example, the remaining NM first parameters of the first category elements are obtained according to the second parameter with the largest index among the M second parameters. Or the remaining NM second parameters of the first category elements are obtained according to the second parameter with the smallest index among the M second parameters. That is, the fourth parameters corresponding to the NM first parameters are merged into one fourth parameter, and the first parameter corresponding to the merged fourth parameter is obtained according to the second parameter with the largest (or smallest) index among the M second parameters. This can also be called N is obtained according to M.

[0058] Solution 8: When N is greater than M, the N first parameters of the first-category elements are re-divided to form M fourth parameters, and then the N first parameters corresponding to the M fourth parameters of the first-category elements are obtained according to the M second parameters of the second-category elements. This can also be called N is obtained according to M.

[0059] Solution 9: When N is less than or equal to M, the first parameter of the first type of element is obtained according to the second parameter of the second type of element; when N is greater than M, the first parameter of the first type of element is obtained according to the third parameter of the third type of element.

[0060] In the above scheme, N is notified in the signaling information for configuring or scheduling the first type of elements. If the above schemes 1, 5, 6, 7, and 8 are adopted, it can also be called N is obtained according to M. At this time, the N value may not be configured in the signaling information for configuring or scheduling the first type of elements.

[0061] Optionally, the N first parameters of the first type of elements correspond to the N fourth parameters of the first type of elements, wherein the fourth parameter includes at least one of the following: a demodulation reference signal (DMRS) port group, a time domain resource group, a frequency domain resource group, and a transmission opportunity of the first type of elements. For example, the N first parameters correspond to N DMRS port groups, each DMRS port group corresponds to a first parameter, and the N DMRS port groups correspond to channels occupying the same time-frequency resources, such as Figure 2 As shown, Figure 2 Schematic diagram of two first parameter TCI states corresponding to two DMRS port groups. Figure 2 In the present invention, a plurality of pre-coding resource block groups (Pre-coding RB Group, PRG) obtain two first parameters, TCI 1 and TCI 2, wherein TCI is a transmission configuration indication (Transmission Configuration Indication), and the two first parameters correspond to two DMRS port groups.

[0062] Or N first parameters correspond to N resource groups, and each resource group corresponds to a first parameter. The resources included in the resource group corresponding to a first parameter may be continuous resources or non-continuous resources. Further, the N resource groups correspond to at least N repeated transmissions of the first type of elements, that is, one resource group may include one or more repeated transmissions of the first type of elements, or multiple resource groups include one transmission opportunity of the first type of elements, where the resources include one or more of time domain resources and frequency domain resources. Specifically, for example, the resource group is a time domain resource group, such as Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of two repeated transmissions in a time slot corresponding to different TCIs. Figure 4Schematic diagram of the mapping relationship between 4 repeated transmissions in 4 slots and 2 TCIs. Figure 3 The two first parameters TCI states (TCI states) (ie, TCI in the figure) correspond to two time domain resource groups in a slot. Figure 4 The two first parameters TCI state in the 4 slots correspond to two time domain resource groups, TCI state1 (i.e. Figure 4 The time domain resource group corresponding to TCI 1 in is {transmission opportunity 1, transmission opportunity 2}, and TCIstate2 (i.e. Figure 4 The time domain resource group corresponding to TCI 2) in the transmission opportunity is {transmission opportunity 3, transmission opportunity 4}, where the channel is repeatedly transmitted in multiple transmission opportunities.

[0063] For example, the resource group is a frequency domain resource group. Figure 5 Schematic diagram of two frequency domain resources corresponding to two TCIs. Two TCIstates correspond to two frequency domain resource groups, such as Figure 5 As shown, TCI state1 (i.e. Figure 5 The frequency domain resource group corresponding to the first TCI state in the Figure 5 The frequency domain resource group corresponding to the second TCI state in the frequency domain is {PRG2,PRG4}, where PRG (Precoding resource block group) is a precoding resource block group. The precoding of channels in the same PRG is the same, and the precoding of channels in different PRGs is the same or different.

[0064] Of course, the present embodiment does not exclude that one second parameter corresponds to more than one first parameter, for example Figure 2 One DMRS port group corresponds to two TCI states. Figure 2 The two DMRS port groups in the table correspond to four TCI states, or Figure 3-4 Each time domain resource in a time domain resource group corresponds to 2 TCI states, which will result in Figure 3-4 The two time domain resource groups in correspond to a total of four TCI states. Figure 5 Each frequency domain resource in a frequency domain resource group corresponds to 2 TCI states, which will result in Figure 5 The two frequency domain resource groups in correspond to a total of four TCIstates. Figure 4In the description, the time domain resources corresponding to {transmission opportunity 1, transmission opportunity 2} are called a time domain resource group. Of course, if the above-mentioned fourth parameter is the transmission opportunity, transmission opportunity 1 and transmission opportunity 2 correspond to two time domain resource groups. Therefore, in this case, the N first parameters of the first type of elements correspond to at least N fourth parameters of the first type of elements, each first parameter corresponds to one or more fourth parameters, and each fourth parameter corresponds to one or more first parameters.

[0065] Similarly, the M second parameters of the second type of elements correspond to the M fourth parameters of the second type of elements. For example, the M second parameters correspond to M DMRS port groups, and each DMRS port group corresponds to a second parameter. Or the M second parameters correspond to M resource groups, and each resource group corresponds to a second parameter. The resources included in the resource group corresponding to a second parameter may be continuous resources or non-continuous resources. Further, the M resource groups correspond to at least M repeated transmissions of the second type of elements, that is, a resource group may include one or more repeated transmissions of the second type of elements, or M frequency domain resource groups correspond to one repeated transmission of the second type of elements, where the resources include one or more of time domain resources and frequency domain resources. Of course, this embodiment does not exclude that a fourth parameter corresponds to more than one second parameter, and a second parameter corresponds to one or more fourth parameters.

[0066] Optionally, the index of each of the N first parameters of the first type of elements in the N first parameters is based on the N fourth parameters corresponding to the first type of elements. For example, if the N first parameters correspond to N time domain resource groups, the index of each of the N first parameters in the N first parameters is obtained according to the index of the time domain resource group corresponding to the first parameter in the N time domain resource groups. For example, the index of the first parameter corresponding to the jth time domain resource group is j, where j = 0, 1, ..., N-1. Optionally, the index of the time domain resource group in the N time domain resource groups can be obtained according to the time domain position order of the starting time domain symbols included in the N time domain resource groups, and the index of the time domain resource group with a later starting position is larger.

[0067] Similarly, the index of each of the M second parameters of the second type element in the M second parameters is obtained according to one of the following methods: the order of the second parameters in the signaling notifying the second parameters; the index of the M fourth parameters of the second type element corresponding to the second type element is obtained. For example, if the M second parameters correspond to M frequency domain resource groups, the index of each of the M second parameters in the M second parameters is obtained according to the index of the frequency domain resource group corresponding to the second parameter in the M frequency domain resource groups. For example, the index of the second parameter corresponding to the jth frequency domain resource group is j, where j = 0, 1, ..., M-1. Optionally, the index of the frequency domain resource group in the M frequency domain resource groups can be obtained according to the order of the starting frequency domain resource positions included in the M frequency domain resource groups, and the frequency domain resource group with a larger starting frequency domain position has a larger index. Or the order of M second parameters in the signaling of the second parameter, for example, the second parameter includes M second parameters corresponding to a mapping relationship in a TCI state mapping table, then the index of the second parameter is obtained according to the order of the M second parameters in an item, for example, the index at the first position is 0, and the index at the second position is 1.

[0068] The above is that there is a corresponding relationship between the ath parameter and the fourth parameter, wherein the ath parameter includes the above-mentioned first parameter and / or second parameter, that is, a includes one and / or two. Of course, the embodiment of the present application does not exclude that the first parameter and / or the second parameter include the fourth parameter, such as the DMRS port group parameter of the first type of element (i.e., the first parameter, wherein the DMRS port group parameter includes at least one of the following: the division parameter of the DMRS port group, the number parameter of the DMRS port group, etc.) is obtained according to the DMRS port group parameter of the second type of element (i.e., the second parameter), wherein the number of DMRS port groups of the first type of element is N, and the number of DMRS port groups of the second type of element is M. Or the frequency domain resource group parameter of the first type of element (i.e., the first parameter) is based on the DMRS port group parameter of the second type of element (i.e., the second parameter), wherein the number of frequency domain resource groups of the first type of element is N, and the number of DMRS port groups of the second type of element is M. Or the number of repeated transmissions of the first type of element is obtained according to the number of repeated transmissions of the second type of element.

[0069] Optionally, when the a-th type element includes a downlink element, the a-th parameter includes at least one of the following parameters: quasi-co-location parameter, transmission mode, demodulation reference signal DMRS port group, time domain resource group, frequency domain resource group, transmission opportunity of downlink element, wherein the quasi-co-location parameter includes one of the following: quasi-co-location reference signal, quasi-co-location assumption, TCI, wherein the quasi-co-location assumption includes an assumption about at least one of the following: Doppler shift, Doppler spread, average delay, delay spread, average gain, spatial reception parameter, other channel characteristic parameters. Wherein, a includes one and / or two, that is, the a-th parameter includes one or more of the first parameter and the second parameter. Optionally, the DMRS ports in a downlink DMRS port group satisfy a quasi-co-location relationship, and the DMRSs of different DMRS port groups do not satisfy the quasi-co-location relationship, or on the same time-frequency resources, the DMRS ports in a DMRS port group satisfy a quasi-co-location relationship, and the DMRSs of different DMRS port groups do not satisfy the quasi-co-location relationship, and on different time-frequency resources, the DMRS ports of the same DMRS port group may not satisfy the quasi-co-location relationship. For example, the same DMRS port group may correspond to different TCI states in different PRB sets (and / or different time domain resource groups). The downlink element includes one of the following: a downlink channel; a downlink signal; an item in the TCIstate mapping table of PDSCH. The TCI state mapping table of the physical downlink shared channel (PDSCH) is shown in Table 1:

[0101] Specifically, the first parameter of the first type of element is obtained according to the second parameter of the second type of element, including one or more of the following scenarios:

[0102] Scenario 1: The first parameter of the uplink element (i.e., the first type of element) is obtained according to the second parameter of the downlink element (i.e., the first type of element), wherein the first parameter includes at least one of the following parameters: spatial parameter, power parameter, transmission mode, and the second parameter includes at least one of the following parameters: quasi-co-location parameter, transmission mode, wherein the number of spatial parameters of the uplink element is N, and the number of quasi-co-location parameters of the downlink element is M. The following is an example in which the first parameter includes the spatial parameter and the spatial parameter of the uplink element is obtained according to the quasi-co-location parameter of the downlink element. The method described below can be similarly adapted to the scenario in which the power parameter of the uplink element is obtained according to the quasi-co-location parameter of the downlink element, except that the spatial parameter in the following description is replaced by the power parameter.

[0103] The uplink element satisfies at least one of the following characteristics: the first parameter is not configured for the uplink element through signaling information; the uplink element includes a PUSCH scheduled by DCI format 0_0, wherein the PUCCH is not configured in the frequency domain bandwidth where the PUSCH is located; at least one spatial parameter is configured in the frequency domain bandwidth where the uplink element is located; the center carrier of the frequency domain bandwidth where the uplink element is located is greater than a predetermined value; the number of sets of uplink measurement reference signals in the frequency domain bandwidth where the uplink element is located is greater than a predetermined value; in the downlink frequency domain bandwidth corresponding to the uplink frequency domain bandwidth where the uplink element is located, at least one quasi-co-site reference signal associated with a spatial reception parameter is configured or activated.

[0104] Optionally, the uplink element includes an uplink channel or signal, such as PUCCH, PUSCH, SRS, a physical random access channel (PRACH), or the uplink element includes an item of a SRI mapping table of PUSCH.

[0105] Optionally, the downlink element includes a downlink channel or signal, such as CORESET, PDSCH, Channel-State Information Reference Signal (CSI-RS), Synchronization Signal and PBCH block (SSB), or the downlink element includes an item in a TCI state mapping table.

[0106] Optionally, the first parameter of the uplink element is acquired according to the second parameter of the downlink element, including one or more of the following scenarios:

[0107] Scenario 1-1: The first parameter of the uplink element is obtained according to the second parameter of the CORESET (i.e., the second type element) with the lowest CORESET identifier (CORESET-ID) in the downlink bandwidth, such as Figure 6 As shown, Figure 6A schematic diagram of obtaining spatial filter information on two time domain resources of a PUCCH according to TCI on two frequency domain resources in a CORESET, wherein the first parameter of PUCCH1 is obtained according to the second parameter of CORESET1, wherein the number N of the first parameters of PUCCH1 is 2, corresponding to the two time domain resource groups of PUCCH1, the two time domain resource groups are in slot (n) and slot (n+1) respectively, and the number M of the second parameter of CORESET1 is 2, corresponding to different frequency domain resources of CORESET1. Optionally, a CORESET (control resource set) is configured in the downlink frequency domain bandwidth corresponding to the uplink frequency domain bandwidth where the uplink element is located.

[0108] Scenario 1-2: The first parameter of the uplink element is obtained according to the second parameter of the CORESET (i.e., the second type element) where the PDCCH that schedules the uplink element is located, wherein the uplink element (i.e., the first type element) has a corresponding PDCCH that schedules it.

[0109] Scenario 1-3: The first parameter of the uplink element is obtained according to a predetermined TCI state (i.e., the second parameter), wherein the predetermined TCI state (i.e., the second parameter) includes one of the following: one or more TCI states with the lowest TCI state index in the TCI state set configured or activated by the PDSCH in the downlink frequency domain bandwidth; TCI states corresponding to one or more codepoints, wherein one codepoint corresponds to one or more TCI states (i.e., M TCI states), where M is equal to the number of TCI states corresponding to one codepoint, codepoint is a codepoint in a TCI state mapping table, the TCI state mapping table is a TCI state mapping table activated by MAC-CE for the PDSCH of the downlink frequency domain bandwidth, and the mapping table is a mapping relationship between the TCI indication field codepoint in the DCI and the TCI state, as shown in Table 1, wherein the codepoint corresponds to the bit field value of the TCI indication field in the DCI. At this time, the TCI state mapping table is called the parameter of PDSCH (i.e., the second type of element). The PDSCH base station may not send it. If PDSCH is sent, the TCI state parameter of PDSCH can be obtained according to the TCI state mapping table and the TCI indication field indicated in the DCI. At this time, the first parameter of the first type of element is obtained according to the second parameter of the second type of element, which can also be called the first parameter of the first type of element is obtained according to the second parameter. Optionally, at this time, CORESET is not configured in the downlink frequency domain bandwidth corresponding to the uplink frequency domain bandwidth where the uplink element is located.

[0110] Scenario 1-4: The spatial parameter corresponding to an item in the SRI mapping table of PUSCH is obtained according to the TCI state corresponding to an item in the TCI state mapping table of PDSCH. For example, the spatial relationship information corresponding to a SRI codepoint in Table 2 or Table 3 is obtained according to the TCI state corresponding to a TCI state copepoint in Table 1. That is, for example, the base station does not notify the SRI mapping table relationship of Table 2 or Table 3 through signaling, but only establishes the mapping relationship of Table 1 through signaling information, and then establishes Table 2 (or Table 3) according to Table 1. For example, the first 4 codepoints in Table 1 whose TCI state number corresponding to the codepoint is equal to 1 constitute the SRI mapping table whose DMRS layer number is equal to 1, as shown in Table 4. When the SRI indication is 1 layer and the SRI codepoint value is equal to 00, the spatial parameters of PUSCH are obtained according to the quasi-co-site reference signal included in TCI state1, and optionally according to the quasi-co-site reference signal associated with the spatial reception parameters in TCIstate1. The first two of the codepoints in Table 1 whose TCI state number is equal to 2 corresponding to the codepoint constitute an SRI mapping table whose DMRS layer number is equal to 2, as shown in Table 5.

[0112] SRI codepoint value TCI codepoint value TCI state 00 000 TCI state1 01 011 TCI state 3 10 100 TCI state 4 11 101 TCI state 8

[0114] SRI codepoint value TCI codepoint value TCI state 00 001 TCI state 2, TCI state 8 01 010 TCI state 4, TCI state 19

[0115] Scenario 1-5: The first parameter of the uplink element is obtained according to the second parameter of the PDSCH. Optionally, when the second parameter is a quasi-co-location parameter and the time interval between the PDCCH and the PDSCH for scheduling the PDSCH is less than a predetermined threshold, the second parameter of the PDSCH is not obtained according to the second parameter indicated in the PDCCH for scheduling the PDSCH, but the quasi-co-location parameter of the PDSCH with a scheduling interval less than a predetermined value is obtained according to one of the following three quasi-co-location parameters:

[0116] Information 1: Quasi-co-location parameters of the CORESET with the lowest CORESET-ID in the associated detection search space in the slot closest to the PDSCH; Information 2: The lowest codepoint in the codepoint corresponding to the TCI state number of 2 in the TCI state mapping table; Information 3: Quasi-co-location parameters of the CORESET with the lowest CORESET-ID in the associated detection search space in the slot closest to the PDSCH and belonging to the predetermined CORESET group.

[0117] Optionally, which of the above three types of information is used to obtain the quasi-co-location parameters of the PDSCH with a scheduling interval less than a predetermined value is determined according to the number of CORESET groups and the maximum number z of TCI states corresponding to a codepoint in the TCI state mapping table. Specifically, when the number of CORESET groups is 2, information three is used, when the number of CORESET groups is 1 and the z value is equal to 1, information one is used, and when the number of CORESET groups is 1 and the z value is greater than 1, information two is used. However, at this time, the quasi-co-location parameter will also be indicated in the PDCCH that schedules the PDSCH, but this quasi-co-location parameter is not used for the reception of PDSCH. We call the quasi-co-location parameter indicated in the PDCCH information four. Optionally, when the first parameter of the uplink element is obtained according to the second parameter of the PDSCH and the second parameter includes the quasi-co-location parameter, it is necessary to determine which of the above information one to four is used to obtain the first parameter of the uplink element. One way is that the first parameter of the uplink element is obtained according to which one of the information one to three is used for PDSCH reception, and the other way is that no matter which one of the information one to three is used for PDSCH reception, the first parameter of the uplink element is obtained according to information four.

[0118] In Table 4 and Table 5, the number of TCI states is equal to the number of DMRS layers of PUSCH, and each TCI state corresponds to a DMRS layer. At this time, an item in the SRI mapping table (i.e., a row in Table 4-Table 5) corresponds to the number of spatial parameters N represented by the number of DMRS layers, that is, the number of the first parameter N is equal to the number of DMRS layers. In this embodiment, it is not excluded that N is equal to the number of DMRS groups of PUSCH, and the DMRS in a DMRS group obtains its spatial information according to the same TCI state. Optionally, the number of DMRS groups is obtained according to the signaling information notified by the base station, or according to the information of the CDM group where the DMRS is located. At this time, the number of the first parameter N is equal to the number of DMRS port groups. Optionally, at this time, PDSCH and PUSCH share a table as shown in Table 1, or PUSCH adopts the first predetermined number of items in Table 1.

[0119] If solution 1 is adopted, in scenario 1-1, it is required that the number N of the first parameters of the uplink elements is less than or equal to the number M of the second parameters of the CORESET (i.e., the second type of elements) with the lowest CORESET-ID in the downlink frequency domain bandwidth. Alternatively, scenario 1-1 is changed to the following rule: the first parameter of the uplink element is required to be obtained according to the second parameter of the CORESET (i.e., the second type of elements) with the lowest CORESET-ID in the CORESET set that meets the predetermined characteristics in the downlink frequency domain bandwidth. The predetermined characteristics include that the second parameter of the CORESET is greater than or equal to N. Figure 7 As shown, Figure 7 The schematic diagram of obtaining the spatial filter information of PUCCH according to CORESET, the number of second parameters of CORESET1 is 1, the number of second parameters of CORESET2 is 2, if the number N of the first parameters of PUCCH is 1, the first parameter of PUCCH is obtained according to the second parameter of CORESET1, if the number N of the first parameters of PUCCH is 2, the first parameter of PUCCH is obtained according to the second parameter of CORESET2, that is, at this time, the CORESET with the lowest CORESET index and the number of second parameters greater than or equal to 2 is CORESET2, not CORESET1.

[0120] In scenario 1-2, it is required that the number M of the second parameters of the CORESET where the PDCCH that schedules the uplink element is located is greater than or equal to the number N of the first parameters of the uplink element.

[0121] In scenario 1-3, the number M of TCI states corresponding to a codepoint is required to be greater than or equal to the number N of the first parameters of the uplink elements.

[0122] In scenario 1-4, the number of DMRS layers N of the uplink element (or the number of DMRS groups N) is less than or equal to the number M of TCI states corresponding to a codepoint.

[0123] If solution 2 is adopted, in scenario 1-1, the more than one downlink element includes downlink elements associated with multiple CORESET groups. For example, the first parameter of the uplink element is obtained according to the second parameter of the CORESET in the multiple CORESET groups. Figure 8 As shown, Figure 8A schematic diagram of spatial filter information on different time domain resources of a PUCCH being obtained according to the lowest CORESET in different CORESET groups, wherein different time domain resource groups of a PUCCH correspond to different first parameters, wherein the first parameter of the first time resource group is obtained according to the second parameter of the lowest CORESET in CORESET group 1, and the first parameter of the second time resource group is obtained according to the second parameter of the lowest CORESET in CORESET group 2. Or at this time, more than one downlink element includes multiple downlink elements associated with the same CORESET group. For example, the first parameter of the uplink element is obtained according to the second parameters of multiple CORESETs in the same CORESET group. Fig. 9 As shown, Fig. 9 This is a schematic diagram showing that spatial filter information on different time domain resources of a PUCCH is obtained according to the lowest two CORESETs in a CORESET group, respectively. Different time domain resources of a PUCCH correspond to different first parameters, wherein the first parameter of the first time resource is obtained according to the second parameter of the lowest CORESET in CORESET group 1, and the first parameter of the second time resource is obtained according to the second parameter of the second lowest CORESET in CORESET group 1.

[0124] Optionally, the more than one downlink element includes downlink elements associated with multiple CORESET groups or includes multiple downlink elements of the same CORESET group, which can be obtained according to signaling information or a predetermined rule. Figure 8 The first parameter of PUCCH is obtained by Fig. 9 The first parameter of PUCCH can be obtained by signaling information or predetermined rules, such as a CORESET group. Fig. 9 When two CORESET groups are used, Figure 8 method to obtain it.

[0125] In scenario 1-2, the PDCCH for scheduling uplink elements is associated with multiple CORESETs, or multiple CORESETs include the PDCCH for scheduling uplink elements, such as one PDCCH is repeatedly transmitted in multiple CORESETs, or multiple CORESETs respectively include a part of the PDCCH for scheduling uplink elements. Optionally, multiple CORESETs belong to one CORESET group, or multiple CORESETs are required to include CORESETs belonging to different CORESET groups, and it is determined whether multiple CORESETs belong to one CORESET group or multiple CORESET groups according to signaling information or predetermined rules.

[0126] In scenario 1-3, the first parameter of the uplink element is obtained based on the TCI state corresponding to more than one codepoint. Optionally, more than one codepoint corresponds to the same TCI state mapping table, such as the lowest and second lowest codepoints of a TCIstate mapping table, or more than one codepoint includes codepoints corresponding to different TCI state mapping tables, where different TCI state mapping tables correspond to different CORESET groups of the same frequency domain bandwidth, such as more than one codepoint includes the lowest one or more codepoints in each TCI state mapping table.

[0127] In scenario 1-4, when the number of DMRS layers N (or the number of DMRS end groups N) is greater than the number of TCIstates corresponding to a codepoint, similar to scenario 1-3, the first parameter of the uplink element is obtained based on the TCI state corresponding to more than one codepoint.

[0128] If scheme 3 is adopted, M first parameters among the N first parameters of the uplink element are obtained according to the M second parameters of the second type of element, and the remaining NM first parameters among the N first parameters of the uplink element are obtained according to the third parameter, wherein the third parameter includes a parameter configured by RRC signaling or MAC-CE signaling or DCI signaling, wherein the third parameter is a proprietary parameter, such as a parameter specially configured for the NM first parameters of the uplink element, or there is a corresponding relationship between the third parameter and the second type of element, and the NM first parameters are obtained according to the third parameter corresponding to the second type of element according to which the second parameter of the second type of element is obtained among the N first parameters of the above-mentioned uplink element, wherein the second parameter is a transmission parameter of the second type of element, and the third parameter is not a parameter required for the transmission of the second type of element, for example, in scenarios 1-1 and 1-2, there is a quasi-co-location relationship between the second parameter and the DMRS of the CORESET, but there is no limitation on the quasi-co-location relationship between the third parameter and the DMRS of the CORESET.

[0129] Or the third parameter is a parameter activated by MAC-CE, for example, the third parameter includes a predetermined TCI state, wherein the predetermined TCI state includes one of the following: one or more TCI states with the lowest TCIstate index in a set of TCI states configured or activated for PDSCH in the downlink frequency domain bandwidth; a predetermined item TCI state corresponding to one or more codepoints in a TCI state mapping table. Optionally, the downlink frequency domain bandwidth includes a downlink frequency domain bandwidth corresponding to the uplink frequency domain bandwidth where the uplink element is located. Specifically, for example, N=2, M=1, one of the two first parameters of the PUCCH (ie, the uplink element) is obtained according to the second parameter of the second type element, and the other first parameter of the PUCCH is obtained according to the predetermined item TCI state included in the predetermined item codepoint in the TCI state mapping table of the PDSCH, wherein the predetermined item TCIstate includes a predetermined item in the multiple TCI states included in the predetermined item codepoint. For example, the predetermined item TCIstate includes the second TCI state in the multiple TCI states included in the predetermined item codepoint. Specifically, assuming that the TCI state mapping table of the PDSCH is shown in Table 6, the predetermined item codepoint includes one of the following:

[0130] A. The lowest codepoint, that is, the codepoint with a value of 0, such as codepoint '00' in Table 1. The other first parameter of the upstream element is obtained according to the second TCI state corresponding to codepoint '00', that is, obtained according to TCIstate 2.

[0131] B. According to the lowest codepoint among the codepoints that meet the predetermined characteristics in the TCI state mapping table, the predetermined characteristic codepoint includes the codepoint in the second parameter that contains the second type element in the codepoint. For example, the second parameter is TCI state 1, then first find the codepoint that includes TCI state 1 in the TCI state mapping table, as shown in Table 1, there are codepint '10' and '11', and then take the lowest of the two, that is, codepoint '10'.

[0132] C. According to the lowest codepoint among the codepoints that meet the predetermined characteristics in the TCI state mapping table, the predetermined characteristic codepoint includes the number of TCI states corresponding to the codepoint that meets the predetermined characteristics. For example, if the number of TCI states is greater than 1, first find the codepoint in the TCI state mapping table whose corresponding number of TCI states is greater than 1, as shown in Table 1, there are codepint'00','10','11', and then take the lowest of these three, that is, codepoint'00'.

[0134]

[0135] After finding the above-mentioned predetermined codepoint, the first parameter is obtained according to the second TCI state (i.e., the predetermined TCI state) in the TCI state corresponding to the above-mentioned codepoint. If the predetermined TCI state is not included in the predetermined codepoint at this time, if the number of TCI states corresponding to the above-mentioned codepoint'00' or codepoint'10' is 1, the fourth parameter part corresponding to the NM first parameters of the uplink element is not sent. For example, if N first parameters correspond to N time domain resource groups, the NM time domain resource groups after the uplink element will not be sent. Or the NM first parameters of the uplink element are all based on the second parameter with the largest (or smallest) index among the M second parameters. Or the fourth parameters corresponding to the N first parameters are divided into M fourth parameters, and the first parameter corresponding to each fourth parameter is obtained according to one of the second parameters in the M second parameters. For example, if N first parameters correspond to N time domain resource groups, then the N time domain resource groups are divided into M time domain resource groups.

[0136] If scheme 4 is adopted, for example, N=1, M=2, 1 first parameter corresponds to 1 DMRS port group (or 1 DMRS port), and 2 second parameters correspond to 2 frequency domain resource groups, then 1 first parameter is obtained according to the second parameter corresponding to the frequency domain resource group with index 0 in the 2 frequency domain resources.

[0137] If Scheme 5 is adopted, in Scenario 1-1 or Scenario 1-2, if the minimum value of the number of second parameters of a CORESET is 1, the number N of the first parameters of the above-mentioned uplink elements (i.e., the above-mentioned first-category elements) is required to be less than or equal to 1; in Scenario 1-3, if the minimum value of the number of TCI states corresponding to a codepoint in a TCI state mapping table is 1, the number N of the first parameters of the above-mentioned uplink elements (i.e., the above-mentioned first-category elements) is required to be less than or equal to 1.

[0138] If Scheme 6 is adopted, in Scenario 1-1 or Scenario 1-2, it is required that the number N of the first parameters of the above-mentioned uplink elements (i.e., the above-mentioned first-category elements) is less than or equal to M_max, where M_max includes one of the following: the maximum number of second parameters of a CORESET; the maximum value of the total number of different second parameters in the set consisting of the second parameters of all CORESETs within a period of time; the maximum value of the total number of different second parameters in the set consisting of the second parameters of all CORESETs in a frequency domain bandwidth within a period of time; the number of second parameters of a CORESET; the total number of different second parameters in the set consisting of the second parameters of all CORESETs within a period of time; the total number of different second parameters in the set consisting of the second parameters of all CORESETs in a frequency domain bandwidth within a period of time.

[0140] If scheme 8 is adopted, for example, N=3, M=2, N first parameters correspond to N time domain resource groups, and M second parameters correspond to M frequency domain resource groups. At this time, the N time domain resource groups are divided into M time domain resource groups, each time domain resource group corresponds to a first parameter, and the first parameter of the j-th time domain resource group of the uplink element is obtained according to the second parameter corresponding to the j-th frequency domain resource group of the second type element, that is, N is obtained according to the value of M at this time. For example, the uplink element includes three time domain resource groups, namely {OFDM1, OFDM2}, {OFDM3, OFDM4}, and {OFDM5, OFDM6}. In this case, {OFDM1, OFDM2}, {OFDM3, OFDM4} may be merged into one time domain resource group {OFDM1, OFDM2, OFDM3, OFDM4}, {OFDM1, OFDM2, OFDM6, OFDM6} is obtained according to the second parameter with index 0, and {OFDM4, OFDM5} is obtained according to the second parameter with index 1. Alternatively, the three time domain resource groups are re-divided into two time domain resource groups, {OFDM1, OFDM2, OFDM3} and {OFDM4, OFDM5, OFDM6}, the first parameter of the first time domain resource group is obtained according to the second parameter with index 0, and the first parameter of the second time domain resource group is obtained according to the second parameter with index 1.

When the number N of the first parameters of the uplink element is greater than the number M of the second parameters of the CORESET with the lowest CORESET-ID, the first parameter is obtained according to the third type of element, wherein the third type of element does not include the CORESET with the lowest CORESET-ID, for example, the third type of element is PDSCH, and the first parameter is obtained according to the predetermined item TCI state in the TCI state mapping table configured for PDSCH in the downlink frequency domain bandwidth corresponding to the uplink frequency domain bandwidth where the uplink element is located, for example, the first parameter is obtained according to the TCI state corresponding to the lowest codepoint among the multiple codepoints with the largest number of TCI states in the TCI state mapping table. Scenarios 1-2, 1-3, and 1-4 can all adopt the method of scheme 9, which will not be repeated here.

Similarly, the above scheme can also be used in the scenario where the second parameter of the downlink element is obtained according to the first parameter of the uplink element.

[0147] Scenario 2: The first parameter of the first uplink element (ie, the first type of element) is obtained according to the second parameter of the second uplink element (ie, the second type of element).

Or when L is greater than 1, L PUCCH resources belong to the same PUCCH resource group, for example, the L PUCCH resources are the L PUCCH resources with the lowest PUCCH resource index in the same PUCCH resource group, such as Fig.12 As shown, Fig.12A schematic diagram of obtaining the first parameters on different time domain resources of PUSCH according to the second parameters of the lowest two PUCCH resources in the same PUCCH group, where L = 2. Optionally, PUCCH resources in a PUCCH resource group are associated with the same group index, and different PUCCH resource groups are associated with different group indexes, and the group index includes the PUCCH resource group index and / or the CORESET group index corresponding to the PUCCH.

The above TCI state mapping table is a TCI state mapping table activated by the MAC-CE command for PDSCH in the frequency domain bandwidth where PDSCH / AP-CSI-RS is located, as shown in Table 1.

[0166] If solution 1 is adopted: requiring N to be less than or equal to M, in scenario 3-1, the number N of the first parameters of PDSCH / AP-CSI-RS is less than or equal to the number M of quasi-co-location parameters of the CORESET with the lowest CORESET index, such as Fig.15 middle, Fig.15 The first parameter of PDSCH / AP-CSI-RS is obtained according to the schematic diagram of the lowest CORESET in the most recent slot. The CORESET in the slot closest to PDSCH / AP-CSI-RS is CORESET2 in slot (n+1), and the number of quasi-co-location parameters of CORESET2 is 1. Then the number of quasi-co-location parameters of PDSCH / AP-CSI-RS cannot be greater than 1. In scenario three-2, the number of first parameters of PDSCH / AP-CSI-RS is less than or equal to the number M of second parameters of the CORESET where the PDSCH / AP-CSI-RS is scheduled.

In scenario three-4, the number N of first parameters of PDSCH / AP-CSI-RS with a scheduling interval less than the first predetermined threshold is less than or equal to the number M of second parameters of the second downlink element whose time domain intersection is not empty.

[0167] If solution 2 is adopted, in scenario 3-1, for example, N=3, M=1, the second parameter of PDSCH / AP-CSI-RS is obtained according to the first parameter of the N CORESETs with the lowest index closest to PDSCH / AP-CSI-RS. At this time, if the transmission modes of the N CORESETs are different, and the transmission mode of PDSCH / AP-CSI-RS can only be one, the transmission mode of PDSCH / AP-CSI-RS is determined according to the transmission mode of one of the N CORESETs, such as determining the transmission mode of PDSCH / AP-CSI-RS according to the transmission mode of the CORESET with the lowest CORESET index among the N CORESETs. Or determine the transmission mode of PDSCH / AP-CSI-RS together according to the transmission modes of N CORESETs.

[0168] In scenario three-3, the first parameter of PDSCH / AP-CSI-RS is obtained according to more than one TCI state, wherein more than one TCI state belongs to one TCI state mapping table, or more than one TCI state includes different TCI state mapping tables, wherein different TCI state mapping tables correspond to PDSCH in a frequency domain bandwidth, and different TCI state mapping tables correspond to different CORESET groups. For example, more than one TCI state includes one of the following: multiple TCI states with the lowest index of TCI state activated by MAC-CE; TCI state corresponding to one or more codepoints with the lowest codepoint in the TCI state mapping table activated by MAC-CE; TCI state corresponding to one or more codepoints with the lowest index in the codepoint set of the corresponding TCI state satisfying the predetermined characteristics in the TCI state mapping table activated by MAC-CE, wherein the codepoint satisfying the predetermined characteristics of the corresponding TCI state includes one of the following: codepoints whose number of corresponding TCI states is greater than a predetermined value; codepoints of predetermined TCIstates are included in the corresponding TCI state.

[0169] For scenario three-4, the first parameter of the first downlink element PDSCH / AP-CSI-RS with a scheduling interval less than the first predetermined threshold is obtained according to more than one second downlink element. For example, when there are multiple second downlink elements that have an intersection with the first downlink element PDSCH / AP-CSI-RS in the time domain, the quasi-co-site reference signal of the first downlink element PDSCH / AP-CSI-RS is obtained according to the second parameters of more than one second downlink elements. Optionally, the intersection of time domain resources occupied by more than one second downlink elements is not empty. Specifically, Figure 13-14 In the embodiment, the first parameter of CSI-RS1 is obtained together with CSI-RS2 and PDSCH1, for example, the TCI state of CSI-RS1 with index 0 is obtained according to the TCIstate of CSI-RS2, and the TCI state of CSI-RS1 with index 1 is obtained according to the TCI state of PDSCH1. Optionally, it is required that CSI-RS2 and PDSCH 1 belong to the same group, or that CSI-RS2 and PDSCH 1 belong to different groups respectively, whether the first parameter of the first downlink element is obtained according to the second parameter of the second downlink element of the same group, or the first parameter of the first downlink element is obtained according to the second parameter of the second downlink element of different groups, can be further obtained according to signaling information or predetermined rules.

At this time, the quasi-co-location parameter of the PDSCH / AP-CSI-RS with an index of 0 is determined according to the quasi-co-location parameter of the CORESET with the lowest COERSET-ID (or the CORESET where the PDCCH scheduling PDSCH / AP-CSI-RS is located), and the quasi-co-location parameter of the PDSCH / AP-CSI-RS with an index of 1 is obtained according to the third parameter, wherein the third parameter includes the parameter configured by RRC signaling or MAC-CE signaling. For example, the third parameter is a proprietary parameter, such as a parameter specially configured for the remaining NM first parameters of the PDSCH / AP-CSI-RS in scenario three-1 or scenario three-2, or there is a corresponding relationship between the third parameter and the CORESET, according to which CORESET's second parameter the M first parameters of the N first parameters of the PDSCH / AP-CSI-RS are obtained, then the NM first parameters are obtained according to which CORESET's corresponding third parameter, the second parameter of one CORESET is the transmission parameter of the CORESET, and the third parameter is not a parameter required for the CORESET transmission, for example, there is a quasi-co-location relationship between the second parameter and the DMRS of the CORESET, but there is no limitation on the quasi-co-location relationship between the third parameter and the CORESET. Or the third parameter is a parameter activated by MAC-CE, for example, the third parameter is a predetermined item TCI state corresponding to a predetermined item codepoint in a TCI state mapping table activated by MAC-CE, wherein the predetermined item TCI state includes a predetermined item acquisition in a plurality of TCI states included in the predetermined item codepoint, for example, the predetermined item TCI state includes a second TCI state acquisition in a plurality of TCI states included in the predetermined item codepoint, and the predetermined item codepoint includes one of the following:

[0171] A. The lowest codepoint, that is, the codepoint with a value of 0, such as codepoint '00' in Table 1, another first parameter of PDSCH / AP-CSI-RS is obtained according to the second TCI state corresponding to codepoint '00', that is, according to TCIstate 2.

[0172] B. According to the lowest codepoint among the codepoints satisfying the predetermined characteristics in the TCI state mapping table, the predetermined characteristics include a codepoint in a second parameter containing a second type of element in the codepoint. For example, the TCI stat of the above-mentioned CORESET (including the CORESET with the lowest CORESET-ID in scenario 3-1, or the CORESET where the PDCCH scheduling PDSCH / AP-CSI-RS in scenario 3-2 is located) is TCI state 1, that is, the second parameter is TCI state 1, then first find the codepoint including TCI state 1 in the TCI state mapping table, as shown in Table 1, there are codepint '10' and '11', and then take the lowest of the two, that is, codepoint '10'.

[0173] C. According to the lowest codepoint among the codepoints that meet the predetermined characteristics in the TCI state mapping table, the predetermined characteristics include the number of TCI states contained in the codepoint meeting the predetermined characteristics, such as the number of TCI states is greater than 1, then first find the codepoint in the TCI state mapping table that includes the number of TCI states greater than 1, as shown in Table 1, there are codepint'00','10','11', and then take the lowest of these three, that is, codepoint'00'.

[0174] Optionally, if the predetermined item codepoint does not include the predetermined item TCI state at this time, for example, the number of TCI states corresponding to the above codepoint '00' or codepoint '10' is 1, then the fourth parameter part corresponding to the NM first parameters of PDSCH / AP-CSI-RS is not sent, for example, N first parameters correspond to N time domain resource groups, and the NM time domain resource groups after PDSCH / AP-CSI-RS are not sent. Or the NM first parameters of PDSCH / AP-CSI-RS are all one of the M second parameters. Or the fourth parameters corresponding to the N first parameters are divided into M fourth parameters, and the first parameters corresponding to each fourth parameter are obtained according to the M second parameters. For example, N first parameters correspond to N time domain resource groups, and the N time domain resource groups are divided into M time domain resource groups at this time.

[0175] If solution 5 is adopted, in scenario 3-4, Figure 13-14, the number of TCI states of CSI-RS1 is less than or equal to the minimum number of TCI states in CSI-RS2 and PDSCH1. Optionally, the TCI state of CSI-RS1 is obtained according to the TCI state of the downlink element of the minimum number of TCI states in CSI-RS2 and PDSCH1. For example, if the number of TCI states of CSI-RS2 is 1 and the number of TCI states of PDSCH1 is 2, the TCI state of CSI-RS1 is obtained according to the TCI state of CSI-RS2.

[0176] If option 6 is adopted, in scenario 3-4, Figure 13-14 , the number of TCI states of CSI-RS1 is less than or equal to the maximum number of TCI states in CSI-RS2 and PDSCH1. Optionally, the TCI state of CSI-RS1 is obtained according to the TCI state of the downlink element with the maximum number of TCI states in CSI-RS2 and PDSCH1. For example, if the number of TCI states of CSI-RS2 is 1 and the number of TCI states of PDSCH1 is 2, the TCI state of CSI-RS1 is obtained according to the TCI state of PDSCH1.

[0177] If scheme 7 is adopted, for example, N=3, M=2, N first parameters correspond to N time domain resource groups of PDSCH / AP-CSI-RS, and M second parameters correspond to M frequency domain resource groups of second type elements, then the first parameter of the time domain resource group indexed by j is obtained according to the second parameter of the frequency domain resource group indexed by j, where j=0,1; finally, the first parameter of NM=1 time domain resource groups is obtained according to the second parameter with the largest index (or the smallest index) among the M second parameters.

[0178] If scheme 8 is adopted, for example, N=3, M=2, N first parameters correspond to N time domain resource groups of PDSCH / AP-CSI-RS, and M second parameters correspond to M frequency domain resource groups of second type elements, then the N time domain resource groups can be divided into M time domain resource groups, and the first parameter of the time domain resource group with index j is obtained according to the second parameter of the frequency domain resource group with index j, where j=0,1.

[0179] If scheme 9 is adopted, when N is less than or equal to M, the first parameter of the first type element is obtained according to the second parameter of the second type element, and when N is greater than M, the first parameter of the first type element is obtained according to the third parameter of the third type element. Specifically, the third type element is different from the second type element. Specifically, in scenario 3-1, the third type element does not include the CORESET with the lowest CORESET-ID, in scenario 3-2, the third type element does not include the CORESET where the PDCCH for scheduling PDSCH / AP-CSI-RS is located, and in scenario 3-3, the third type element does not include the predetermined item TCI state. In scenario 3-4, the third type element does not include the second downlink element.

[0180] Optionally, when the first parameter includes the first transmission mode of the first downlink element and the second parameter includes the second transmission mode of the second downlink element, the obtaining of the second parameter of the second information element according to the first parameter of the first information element includes obtaining the second transmission mode of the second downlink element according to the first transmission mode of the first downlink element, for example, according to scenario three-1, the transmission mode of the PDSCH / AP-CSI-RS with a scheduling interval less than a predetermined threshold is obtained according to the transmission mode of COREST with the lowest CORESET-ID. Specifically, the mapping relationship between the N first parameters and the fourth parameter of the PDSCH / AP-CSI-RS with a scheduling interval less than the predetermined threshold is determined according to the mapping relationship between the M second parameters and the fourth parameter of the COREST with the lowest CORESET-ID, or the number of the fourth parameters of the PDSCH / AP-CSI-RS with a scheduling interval less than the predetermined threshold is determined according to the number of the fourth parameters of the COREST with the lowest CORESET-ID; or the number N of the first parameters of the PDSCH / AP-CSI-RS with a scheduling interval less than the predetermined threshold is determined according to the number M of the second parameters of the COREST with the lowest CORESET-ID.
