[0057] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0058] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0060] To facilitate understanding of the solution proposed in this application, the relevant content will be introduced first.

[0061] In 5G NR, the downlink control channel resource set is defined by CORESET. Due to the large transmission bandwidth of 5G systems and the varying support capabilities of user equipment (UEs), CORESET is used to constrain the time-frequency domain resource scheduling of the PDCCH in order to adapt to different bandwidths and reduce the blind detection complexity of the Physical Downlink Control Channel (PDCCH).

[0062] A CORESET occupies 1-3 time-domain OFDM symbols and can be located anywhere within a time slot. The scheduling location of these time-domain OFDM symbols varies depending on the scenario. A CORESET occupies multiple resource blocks (RBs) in the frequency domain, and the configured frequency domain resource locations must not exceed the frequency domain range of the bandwidth part (BWP). The granularity of the frequency domain resource configuration for a CORESET is 6, which adapts to different REG Bundle configurations and effectively reduces resource fragmentation.

[0063] A Resource Element Group (REG) occupies one OFDM symbol in the time domain and 12 consecutive subcarriers (one resource block) in the frequency domain. Within a REG, the subcarriers at indices 1, 5, and 9 are mapped to the PDCCH Demodulation Reference Signal (DMRS), while the remaining nine subcarriers are mapped to the PDCCH data signal. A REG Bundle is a collection of REGs that are consecutive in the frequency or time-frequency domains, and the number of REGs constituting a REG Bundle can be 1, 2, 3, or 6.

[0064] The Control Channel Element (CCE) is the basic unit that makes up the PDCCH. One CCE occupies 6 REGs. The number of CCEs in the PDCCH is called the aggregation level, and the aggregation level can be 1 / 2 / 4 / 8 / 16.

[0065] Within a CoreSet, the mapping method from CCE to REG resources includes interleaving and non-interleaving modes. For interleaving, CCEs can be mapped across the entire CoreSet using a defined interleaving formula, thereby obtaining frequency diversity gain and achieving randomization of inter-cell interference. For non-interleaving, although some frequency diversity gain will be lost, the base station can schedule the PDCCH on time-frequency resources with better channel quality if it knows the downlink radio channel in advance, thereby obtaining a certain scheduling gain.

[0066] In 5G, CORESET resources occupy a maximum of 3 symbols in the time domain and do not support more than that. If the definition of CORESET is still used in 6G, there is currently no concrete solution to support CORESET transmission using more than 3 symbols.

[0067] To address the aforementioned technical problems, embodiments of this application provide a resource determination method, apparatus, device, medium, and chip. The method and apparatus are based on the same concept. Since the methods and apparatus solve problems in similar ways, their implementations can be mutually referenced, and repeated details will not be elaborated further.

[0068] like Figure 1 The diagram shown is a flowchart illustrating a resource determination method provided in an embodiment of this application. This method is applied to a terminal, i.e., executed by the terminal. The method may include:

[0069] Step 101: Determine the resource locations within the control resource set, where the control resource set occupies N symbols, and N is a positive integer greater than 3;

[0070] The location of resources within the control resource set is determined based on at least one of the following rules:

[0071] The index of the resource unit group (REG) is associated with the first rule that controls the relationship between resource locations within the resource set;

[0072] A second rule relating the index of a collection of resource unit groups (REG bundles) to the indexes of the REGs contained within those REG bundles;

[0073] The third rule for the association between control channel elements CCE and REG.

[0074] The resource determination method of this application embodiment determines the resource locations within a CORESET that supports more than 3 symbols of control resources in the time domain. Specifically, based on the first rule relating REG indexes to resource locations within the CORESET, the second rule relating REG bundle indexes to the indices of REGs contained within the REG bundle, and / or the third rule relating CCEs to REGs, the size, index, and resources of REGs, REG bundles, and / or CCEs within the CORESET are determined. This enables the CORESET to use more than 3 symbols for transmission, further improving the coverage performance of the downlink control channel, supporting a higher CCE aggregation level, or supporting more downlink control channel resources in low-bandwidth scenarios.

[0075] In some embodiments, the first rule includes at least one of the following:

[0076] First sub-rule: Among the N symbols used to control the resource set, REGs are numbered in the order of time domain first and then frequency domain. The size of the REG bundle is L REGs, where L = 2, 3, 6 or N.

[0077] Here, the first sub-rule applies when the control resource set CORESET supports a time domain length of more than 3 symbols. Of course, the first sub-rule also applies when the CORESET supports a time domain length of 1, 2, or 3 symbols.

[0078] Optionally, the first sub-rule is as follows:

[0079] In the N symbols occupied by the control resource set, REG starts from the first OFDM symbol of the control resource set and the lowest numbered RB, and numbers them from 0 in the order of time domain first and then frequency domain.

[0080] Second sub-rule: Among the N symbols used to control the resource set, REGs are numbered in the order of frequency domain first and time domain second. The size of the REG bundle is L REGs, where L = 2, 3 or 6.

[0081] Here, the second sub-rule applies when the control resource set CORESET supports a time domain length of more than 3 symbols. Of course, the second sub-rule also applies when the CORESET supports a time domain length of 1, 2, or 3 symbols.

[0082] Optionally, the second sub-rule is as follows:

[0083] In the N symbols occupied by the control resource set, REG starts from the first OFDM symbol of the control resource set and the lowest numbered RB, and numbers them from 0 in the order of frequency domain first and time domain second.

[0084] Third sub-rule: When the N symbols occupied by the control resource set are divided into A symbols and B symbols, REGs are numbered in the first A symbols in the order of time domain first and then frequency domain, and REGs are numbered in the last B symbols in the order of time domain first and then frequency domain. The size of the REG bundle is L REGs, where L is divisible by A and L is divisible by B.

[0085] Here, the third sub-rule applies to cases where the control resource set CORESET supports a time domain length of more than 3 symbols, such as 4, 5, or 6 symbols. Of course, the third sub-rule also applies to cases where the CORESET time domain length supports 1, 2, or 3 symbols.

[0086] Optionally, the value of A can be in the range of 1 to 3, and the value of B can be in the range of 1 to 3.

[0087] Optionally, the third sub-rule is specifically:

[0088] When the N symbols occupied by the control resource set are divided into the first A symbols and the last B symbols, REG starts from the first OFDM symbol of the first A symbols and the lowest numbered RB, and starts numbering from 0 in the order of time domain first and then frequency domain.

[0089] REG starts from the first OFDM symbol of the last B symbols and the lowest numbered resource block RB, and continues the numbering of the first A symbols in the order of time domain first and then frequency domain, or starts numbering from 0.

[0090] In the embodiments of this application, optionally, a REG occupies one or more resource blocks (RBs) in an orthogonal frequency division multiplexing (OFDM) symbol.

[0091] In some embodiments, the second rule includes:

[0092] The REG bundle at index i contains REGs with indices {iL, iL+1, ..., iL+L-1}, where L is the size of the REG bundle. and in, This indicates the number of REGs contained in the control resource set. This indicates the number of RBs contained in the control resource set. This indicates the number of symbols contained in the control resource set.

[0093] In some embodiments, the third rule includes at least one of the following:

[0094] The first mapping relationship between CCE and REG is the index j of the REGbundle contained in the CCE with index j;

[0095] The second mapping relationship between CCE and REG is as follows: the index of the REGbundle contained in the CCE with index j is... X is a predefined value or variable, representing the number of REGs contained in a CCE, and It is an integer;

[0096] The third mapping relationship between CCE and REG is as follows: the index of the REGbundle contained in the CCE with index j is f(j);

[0097] Where f(·) represents the interleaver.

[0098] Furthermore, if the first rule includes a third sub-rule, and the third rule is a second mapping relationship between CCE and REG, then the second mapping relationship is obtained by uniformly interleaving all REG bundles in A symbols and B symbols, or the second mapping relationship is obtained by interleaving the REG bundles in A symbols and the REG bundles in B symbols respectively.

[0099] In some embodiments, the first rule includes a third sub-rule, and A = B;

[0100] When the aggregation level of CCEs is an even number M, X CCEs are mapped to A symbols, and the remaining Y CCEs are mapped to B symbols. The frequency domain resource positions occupied by the Y CCEs in the B symbols are the same as those occupied by the X CCEs in the A symbols. M.

[0101] The following sections will explain the specific implementation of the resource determination method in this application using the following methods.

[0102] Method 1 determines the resource location within the control resource set by the first sub-rule, the second rule, and the third rule, which is the second mapping relationship between CCE and REG. The CORESET time domain length supports 1 / 2 / 3 / 6 symbols.

[0103] When the CORESET time domain length supports 6 symbols, the size of the REG bundle is 6, meaning that a REG bundle or CCE resource always occupies all the time domain symbols of the CORESET.

[0104] The size, numbering, and resource determination methods for REG / REG bundle / CCE are as follows:

[0105] One REG occupies one RB in one OFDM symbol. REGs are numbered starting from 0, following the order of time domain first and then frequency domain.

[0106] A REG bundle i contains REGs of {iL, iL+1, ..., iL+L-1}, where L is the size of the REG bundle. and in, This indicates the number of REGs contained in the control resource set. This indicates the number of RBs contained in the control resource set. Indicates the number of symbols contained in the control resource set;

[0107] A CCE j contains a REG bundle of Where f(·) represents the interleaver.

[0108] To facilitate understanding of Method 1, the following explanation is provided through Example 1.

[0109] Example 1 (Method 1)

[0110] See Figure 2 In the graph, the horizontal axis represents the time domain, the vertical axis represents the frequency domain, and the colored areas represent the time-frequency resources occupied by the CORESET. Each colored cell represents a REG, with the horizontal axis corresponding to one symbol and the vertical axis corresponding to one RB. When the CORESET time domain length is 6 symbols, the REG bundle size is 6. By defining the REG bundle size as 6, it can be guaranteed that in this method, a REG bundle or CCE resource always occupies all symbols in the CORESET time domain.

[0111] The CORESET resource in this embodiment contains 72 REGs, which are numbered starting from 0, first in the time domain and then in the frequency domain. A REG bundle occupies 6 consecutive REGs, which is 6 symbols in the time domain and one RB in the frequency domain. This embodiment contains a total of 12 REG bundles.

[0112] If interleaving is not used, that is, if the third rule is the first mapping relationship between CCE and REG, then the resources occupied by CCE j are equal to the resources occupied by REG bundle j, that is, the REG bundle index j contained in CCE with index j.

[0113] Figure 2 This is the corresponding result of the CCE index (number) and REG bundle index (number) after interleaving, with interleaving parameters R=2 and Nshift=0.

[0114] Method 2 determines the resource location within the control resource set by the third sub-rule, the second rule, and the third rule being the second mapping relationship between CCE and REG, where the CORESET time domain length supports 1 / 2 / 3 / 4 / 5 / 6 symbols.

[0115] When the CORESET time domain length supports 4 / 5 / 6 symbols, the number of symbols is divided into A+B, where A ranges from 1 to 3 and B ranges from 1 to 3.

[0116] The size, numbering, and resource determination methods for REG / REG bundle / CCE are as follows:

[0117] A REG occupies one RB in an OFDM symbol. First, the REG starts from the first OFDM symbol and the lowest numbered RB in the first A symbols of the CORESET, and is numbered from 0 in the order of time domain first and then frequency domain. Then, it starts from the first OFDM symbol and the lowest numbered RB in the last B symbols of the CORESET, and continues the numbering in the first A symbols in the order of time domain first and then frequency domain, or starts numbering from 0.

[0118] The candidate set for the size of a REG bundle is the set of numbers divisible by both A and B, chosen from 2, 3, and 6; a REG bundle i contains REGs of {iL, iL+1, ..., iL+L-1}, where L is the size of the REG bundle. and in, This indicates the number of REGs contained in the control resource set. This indicates the number of RBs contained in the control resource set. Indicates the number of symbols contained in the control resource set;

[0119] A CCE j contains a REG bundle of Where f(·) represents the interleaver.

[0120] In the interleaving scenario, all REG bundles in symbols A and B are interleaved together. Alternatively, in the interleaving scenario, the REG bundles in symbols A and B are interleaved separately. Specifically, interleaving can be performed according to the 5G NR scheme.

[0121] Furthermore, if A = B, then the expanded symbol number cannot contain an odd number of symbols.

[0122] When the aggregation level of CCEs is an even number M, X CCEs are mapped to A symbols, and the remaining Y CCEs are mapped to B symbols. The frequency domain resource positions occupied by the Y CCEs in the B symbols are the same as those occupied by the X CCEs in the A symbols. M.

[0123] That is, when the CCE aggregation level is even, half of the CCEs are mapped in A symbols and the other half are mapped in B symbols. First, the resources occupied by the CCEs in A symbols are determined, and then the resources occupied in B symbols are determined to be the same as the CCEs in A symbols in the frequency domain.

[0124] To facilitate understanding of Method 2, the following explanation will be provided using Example 2.

[0125] Example 2 (Method 2)

[0126] When the CORESET time domain length is greater than 3 symbols, the CORESET time domain length contains A+B symbols. In the non-interleaved case, the size of the REG bundle is equal to 6.

[0127] In the case of intertwining,

[0128] If A = B = 2, then the size of the REG bundle is either 2 or 6; if A = B = 3, then the size of the REG bundle is either 3 or 6.

[0129] If A = 1 and B = 3 or A = 3 and B = 1, then the size of the REG bundle can be either 3 or 6.

[0130] If A = 2 and B = 3, or A = 3 and B = 2, then the size of the REG bundle can be equal to 6.

[0131] See Figure 3 In the figure, the horizontal axis represents the time domain, the vertical axis represents the frequency domain, and the colored areas represent the time-frequency resources occupied by the CORESET. Each colored cell represents a REG, with one symbol on the horizontal axis and one RB on the vertical axis. In this embodiment, the CORESET time domain length includes 3+2 symbols, and the size of the REG bundle is equal to 6.

[0132] The CORESET resource in this embodiment contains 60 REGs. The REGs are numbered starting from 0 in the first 3 symbols in the order of time domain first and then frequency domain, and then in the last 2 symbols in the order of time domain first and then frequency domain.

[0133] A REG bundle occupies 6 consecutive REGs. The REG bundles are numbered in the first 3 symbols in ascending order of frequency domain, and then in the last 2 symbols in ascending order of frequency domain.

[0134] If interleaving is not used, then the third rule is the first mapping relationship between CCE and REG. In this case, the resources occupied by CCE j are equal to the resources occupied by REG bundle j, which is the index j of the REG bundle contained in CCE with index j.

[0135] If interleaving is used, all REG bundles in symbols A and B are interleaved together; or the REG bundles in symbols A and B are interleaved separately according to the 5GNR scheme.

[0136] It should be noted that, based on the idea of ​​this embodiment, the number of CORESET symbols can be further expanded to A+B+C, or A+B+C+D, etc., where the values ​​of A / B / C / D are 1 / 2 / 3, which should also fall within the scope of protection of this application.

[0137] Example 3 (Method 2, limited to the case where A = B)

[0138] When the CORESET time domain length is greater than 3 symbols, the CORESET time domain length contains A+B symbols and A=B. In the non-interleaved case, the size of the REG bundle is equal to 6.

[0139] In the case of intertwining,

[0140] If A = B = 2, then the size of the REG bundle is either 2 or 6;

[0141] If A = B = 3, then the size of the REG bundle is either 3 or 6.

[0142] See Figure 4 In the figure, the horizontal axis represents the time domain, the vertical axis represents the frequency domain, and the colored areas represent the time-frequency resources occupied by the CORESET. Each colored cell represents a REG, with one symbol on the horizontal axis and one RB on the vertical axis. In this embodiment, the CORESET time domain length includes 3+3 symbols, and the size of the REG bundle is equal to 6.

[0143] The CORESET resource in this embodiment contains 72 REGs. The REGs are numbered starting from 0 in the first three symbols, following a time-domain-then-frequency-domain sequence. Then, in the next three symbols, they are numbered again, following a time-domain-then-frequency-domain sequence (either continuing the numbering from the first three symbols or starting from 0). Figure 4 (The diagram in the image indicates that it starts from 0).

[0144] A REG bundle occupies 6 consecutive REGs. The REG bundles are numbered in the first 3 symbols in ascending order of frequency domain, and then in the last 3 symbols in ascending order of frequency domain (continuing the numbering in the first 3 symbols or starting from 0).

[0145] This scheme can be limited to the case where the CCE aggregation level is even. When the CCE aggregation level is not even, it can be used when the time domain length of CORESET is greater than or equal to 3 symbols, or the method in Example 2 can be used.

[0146] For cases where the CCE aggregation level is an even number 2P, first determine the resources occupied by P CCEs in the first 3 symbols. For example, if the CCE aggregation level is 2, first determine the resources occupied by one CCE in the first 3 symbols (using the method of determining the resources of one CCE under three symbols of CORESET). For example, if the occupied REG bundle is 4, then another CCE in the last 3 symbols occupies the resources at the same frequency domain position, such as occupying the resources of the same REG bundle number.

[0147] It should be noted that, based on the idea of ​​this embodiment, the number of CORESET symbols can be further expanded to an integer multiple of A, and the value of A can be 1 / 2 / 3, which should also fall within the scope of protection of this application.
