[0056] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0057] In the description of this application, if there is a description of first or second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0058] Control Resource Set (CORESET), the resource mapping mode from CCE to REG (Resource Element Group) includes interleaved and non-interleaved modes; in non-interleaved mode, every 6 REGs form a CCE. When CORESET contains an OFDM time domain symbol, the REG index in CCE is arranged from low to high in the frequency domain starting from 0. In one REG, the subcarriers of Index 1, 5, and 9 are mapped to PDCCH DMRS signals (demodulation reference signal sequence), and the remaining 9 subcarriers are mapped to PDCCH (Downlink Control Information) data signals.

[0059] In the communication between the base station and the communication equipment (such as mobile phones), it is necessary to know the control resource set to determine the starting position and size of the CCE (control channel element) so that the communication equipment can normally parse the information transmitted on the communication link. Specifically, according to the control resource set, the aggregation level and candidate set are determined, and the starting position and size of the CCE are calculated in combination with the CRNTI (Cell-Radio Network Temporary Identifier). However, in actual application, for security reasons, a third-party communication device is required to monitor the communication link. Since the third-party communication device cannot obtain the control resource set, it is impossible to determine the starting position and number of CCE through the aggregation level and candidate set CRNTI.

[0060] For example, for Figure 1 In the communication system shown, in order to ensure normal communication between the base station 200 and the communication device 100 (referring to a device that can receive and analyze the signal of the base station 200 and can communicate with the base station 200, such as a mobile terminal: a mobile phone, a tablet, a computer, etc.), the communication device 100 receives the uplink scheduling control information and the downlink scheduling control information from the base station 200 through the PDCCH; when the CORESET of the communication device 100 is known, the starting position and aggregation level of the CCE can be analyzed according to the mapping method of the CORESET, so that the data information sent by the base station 200 can be analyzed normally. For the non-interleaved mode, since the REG in the scheduling control information and the CCE are in a one-to-one correspondence, when the CORESET is unknown, the starting position of the CCE can be blindly detected by exhaustive iteration, but this efficiency is low. Therefore, when the CORESET of the communication device 100 is unknown, it is imperative to quickly and accurately determine the starting position and aggregation level of the CCE to quickly analyze the scheduling control information on the base station 200 side to analyze the data. Based on this, the present application proposes a method, unit, device and storage medium for determining resource information of a control channel unit for determining the starting position of CCE and the corresponding number of CCEs when the control resource set is unknown and CCE is non-interleaved.

[0061] On the one hand, the present application proposes a device for determining resource information of a control channel unit, such as Figure 2 As shown, it includes a generating module 110 , an extracting module 120 , a processing module 130 and a first information set calculating module 140 .

[0062] The generating module 110 is used to obtain a scrambling code identification number under the full bandwidth, and generate a first demodulation reference signal sequence under the full bandwidth according to the scrambling code identification number.

[0063] The extraction module 120 is used to receive the scheduling control information under the full bandwidth, and extract the second demodulation reference signal sequence from the scheduling control information.

[0064] The processing module 130 is configured to process the first demodulation reference signal sequence and the second demodulation reference signal sequence in units of one control channel unit to obtain a normalized correlation value set.

[0065] The first information set calculation module 140 is used to calculate several first information sets according to a normalized correlation value set and a preset aggregation level set; wherein each element in each first information set corresponds to a group of first resource information; the first resource information includes the starting position of the control channel unit and the corresponding aggregation level.

[0066] The resource information determination device of the control channel unit further includes a storage module 150, which is used to store data information and is electrically connected to the first information set calculation module 140. The generation module 110, the extraction module 120 and the processing module 130 are electrically connected; the processing module 130 and the first information set calculation module 140.

[0067] Exemplarily, the extraction module 120 parses the scheduling control information of the base station 200 to obtain a second demodulation reference signal sequence. The generation module 110 generates a first demodulation reference signal sequence under the full bandwidth according to the scrambling code identification number; at this time, the processing module 130 processes the first demodulation reference signal sequence and the second demodulation reference signal sequence to obtain a normalized correlation value set. The processing module 130 obtains several first information sets according to the normalized correlation value set and the preset aggregation level set, wherein each element in each first information set corresponds to a set of first resource information; the first resource information includes the starting position predicted by the control channel unit and the corresponding aggregation level. At this time, the data information transmitted on the communication link is parsed according to the several first information sets obtained by the first information set calculation module 140.

[0068] It should be noted that the resource information determining device of the control channel unit may be an independent chip unit integrated into the controller of the communication device 100 , or may be a separate communication device 100 .

[0069] The devices and application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Those skilled in the art will appreciate that with the evolution of the system architecture and the emergence of new application scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0070] It can be understood by those skilled in the art that Figure 2The device shown does not constitute a limitation on the embodiments of the present application, and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

[0071] Based on Figure 1 The system architecture shown proposes various embodiments of the method for determining resource information of the control channel unit of the embodiment of the present application.

[0072] like Figure 3 As shown, the method for determining resource information of a control channel unit is applied to a communication device 100; the method comprises:

[0073] Step S100: Acquire a scrambling code identification number under full bandwidth, and generate a first demodulation reference signal sequence under full bandwidth according to the scrambling code identification number.

[0074] For both the base station 200 and the communication device 100, the scrambling code identification number is known. For example, for the communication device 100, in a scenario where the control resource set is unknown and the CCE is not interleaved, assuming that the frequency domain start position of the full bandwidth is 0 and the size is 270 RBs (Resource Block, indicating 12 consecutive subcarriers in frequency), the first demodulation reference signal sequence generated locally is ,in, ;in, ; Indicates the total number of PDCCH DMRS symbols, which is obtained based on the fact that each RB has 3 subcarriers mapped to the PDCCH DMRS.

[0075] Step S200: receiving scheduling control information under full bandwidth, and extracting a second demodulation reference signal sequence from the scheduling control information.

[0076] It should be noted that the second demodulation reference signal sequence is a sequence generated by the base station 200 according to the scrambling code identification number pdcch-DMRS-ScramblingID. Assume that the second demodulation reference signal sequence is ,but .

[0077] Step S300: Taking one control channel unit as a unit, the first demodulation reference signal sequence and the second demodulation reference signal sequence are processed to obtain a normalized correlation value set.

[0078] It should be noted that each normalized correlation value in the normalized correlation value set is a power correlation calculated in units of CCE. In the non-interleaved mode, each first demodulation reference signal sequence and each second demodulation reference signal sequence can be divided into a number of subsequences in units of CCE. At this time, according to the power correlation between the two subsequences corresponding to the first demodulation reference signal sequence and the second demodulation reference signal sequence, the difference between the first demodulation reference signal sequence and the second demodulation reference signal sequence can be known.

[0079] It should be noted that, assuming the normalized correlation value set ,in ,in represents the total number of elements in the normalized correlation value set; then .

[0080] Step S400, calculate and obtain several first information sets according to a normalized correlation value set and a preset aggregation level set; wherein each element in each first information set corresponds to a group of first resource information; the first resource information includes a starting position of a control channel unit and a corresponding aggregation level.

[0081] It should be noted that the aggregation level indicates the degree of aggregation, that is, the number of CCEs; usually, the aggregation level can be divided into five levels, namely, 1, 2, 4, 8, and 16, and the set of these five levels is the aggregation level set. By processing the normalized correlation value set at each aggregation level in turn, it can be determined whether the CCE at the predicted starting position at the aggregation level is valid; that is, whether the CCE corresponding to the first resource information is valid.

[0082] Therefore, a first demodulation reference signal sequence is constructed at the full bandwidth through the scrambling code identification number, so that an association is established between the first demodulation reference signal sequence and the second demodulation reference signal sequence extracted from the scheduling control information transmitted in the actual link; at this time, based on the normalized correlation value set corresponding to the first demodulation reference signal sequence and the second demodulation reference signal sequence obtained, the validity of the power correlation of the CCE at the same starting position corresponding to the first demodulation reference signal sequence and the second demodulation reference signal sequence can be obtained to determine the starting position of the CCE and the corresponding number of CCEs.

[0083] In an optional embodiment, if Figure 4 As shown, step S300 includes:

[0084] Step S310: divide the first demodulation reference signal sequence and the second demodulation reference signal sequence respectively according to the number of symbols occupied by one control channel unit to obtain a plurality of sequence pairs, wherein each sequence pair includes a first demodulation reference signal subsequence and a second demodulation reference signal subsequence corresponding to the first demodulation reference signal subsequence.

[0085] Step S320, sequentially acquiring sequence pairs; and performing correlation calculation based on the first demodulation reference signal subsequence and the second demodulation reference signal subsequence in the sequence pairs to obtain a normalized correlation value corresponding to the sequence pairs.

[0086] Step S330: sort the corresponding normalized correlation values ​​in sequence according to the order of the positions of each sequence pair to form a normalized correlation value set.

[0087] It should be noted that, assuming that the position of each symbol of the first demodulation reference signal sequence is They are , the number of symbols occupied by the control channel unit is 18, then the number of the sequence pair is .

[0088] In an optional embodiment, if Figure 5 As shown, for each sequence pair, step S320 includes:

[0089] Step S321: Calculate a correlation value between a first demodulation reference signal subsequence and a second demodulation reference signal subsequence.

[0090] That is, the correlation value between the first demodulation reference signal subsequence and the second demodulation reference signal subsequence with the same number is calculated.

[0091] Step S322: Obtain average power according to the second demodulation reference signal subsequence.

[0092] Step S323: Divide the correlation value by the average power to obtain a normalized correlation value.

[0093] In an optional embodiment, if Figure 6 As shown, step S321 includes:

[0094] Step S3211: Conjugate-multiply each symbol in the first demodulation reference signal subsequence and the symbol at the corresponding position in the second demodulation reference signal subsequence to obtain a first subsequence.

[0095] It should be noted that the corresponding position means that the index position of the symbol in the first demodulation reference signal subsequence and the second demodulation reference signal subsequence is the same. Assuming that the first demodulation reference signal subsequence is at the first position in the first demodulation reference signal sequence; the second demodulation reference signal subsequence is at the second position in the second demodulation reference signal sequence; then the first position is equal to the second position.

[0096] Step S3212: Calculate the square of the modulus of the sum of all values ​​in the first subsequence to obtain a correlation value.

[0097] In an optional embodiment, if Figure 7As shown, step S322 includes:

[0098] Step S3221: Calculate the modulo sum of each symbol in the second demodulation reference signal subsequence.

[0099] Step S3222: Calculate the average value of the sum to obtain the average power.

[0100] In an optional embodiment, if Figure 8 As shown, step S400 includes:

[0101] Step S410: Obtain each aggregation level to be predicted in the aggregation level set.

[0102] Step S420, according to the normalized correlation value set and each aggregation level, obtain a second information set corresponding to the aggregation level; wherein; each element in the second information set corresponds to a group of second resource information, and the second resource information includes the starting position predicted by the control channel unit, the normalized correlation value corresponding to the starting position, and the value.

[0103] Step S430: Perform validity processing on each second information set to obtain a corresponding first information set.

[0104] In an optional embodiment, if Fig. 9 As shown, step S420 includes:

[0105] Step S421: According to the aggregation level, obtain the number N of normalized values ​​used to evaluate the effectiveness of the control channel unit; wherein N is the difference between the total number of elements in the normalized correlation value set and the number of control channel units corresponding to the aggregation level plus 1.

[0106] It should be noted that since CCE is set continuously, for a valid CCE, its possible starting position is 0~N. Assuming that the total number of elements in the normalized correlation value set is 45 and the aggregation level is 3, then N=45-3+1=43. That is, the starting position of CCE is 0~43. At this time, when the starting position of CCE is When , CCE should be at 23, 24, 25.

[0107] Step S422: When the starting positions are any values ​​from 0 to N, the sum of normalized correlation values ​​of M consecutive control channel units starting from the starting positions is calculated; M is the number corresponding to the aggregation level.

[0108] The aggregation level is For example, Aggregation level set The elements. Then the possible starting position of CCE is is 0~N, that is Each starting position At the aggregation level The corresponding normalized correlation value is

[0109] It should be noted that when the starting position matches the aggregation level, the normalized correlation values ​​corresponding to numbers N to N+M should be valid, and the sum value obtained at this time should meet a certain threshold value.

[0110] Step S423: Set each obtained sum value as the normalized correlation value sum value of the corresponding starting position.

[0111] That is, for the aggregation level For The normalized correlation value and value of .

[0112] Step S424: Take each starting position, the corresponding normalized correlation value and the value as a set of second resource information, and obtain a second information set according to each second resource information.

[0113] The second information set .in, The corresponding aggregation level is , the starting position is The normalized correlation values ​​and values ​​of .

[0114] In an optional embodiment, if Fig.10 As shown, step S430 includes:

[0115] Step S431: compare the normalized correlation value and value in each second resource information in the second information set with a preset threshold value.

[0116] Assume the threshold is ,but Indicates that it is valid. Its corresponding starting position It may be the starting position of the real CCE.

[0117] Step S432: If the normalized correlation value and value are less than or equal to the threshold value, the second resource information is deleted to update the corresponding second information set.

[0118] Step S433: Combine the predicted starting position of the control channel unit and the corresponding aggregation level in the updated second information set to form a first information set.

[0119] The first information set .in, Corresponding location information.
