Description

Technical Field

[0001] This application relates to the field of 5G technology, and in particular to a method, apparatus and storage medium for content detection of DCI0-1 of PDCCH in a 5G system. Background Technology

[0002] NR (New Radio, 5G wireless network) air interface monitoring equipment is used to monitor the radio environment, locate and identify the UE (User Equipment) and base station by detecting the wireless signals of uplink and downlink communication. The air interface monitoring equipment does not interact with the base station or mobile phone; it only silently monitors the radio signals in the air interface to achieve wireless signal identification.

[0003] The PDCCH (Physical Downlink Control Channel) payload is DCI (Downlink Control Information). DCI has various formats (DCI1-0, DCI1-1, DCI0-0, DCI1-1, etc.). DCI0-1 is used by the UE in RRC (Radio Resource Control) connected state to indicate the physical parameter configuration of the PUSCH (Physical Uplink Shared Channel). Only by parsing the correct DMRS (Demodulation Reference Signal) configuration of the PUSCH through DCI0-1 can the uplink synchronization point of the PUSCH be obtained. The energy value calculated based on this synchronization point is the desired value.

[0004] The parsing of DCI0-1 depends on the UE's context. The same bit can have different meanings in different contexts. For the UE, its parameter configuration can be obtained through the RRC Reconfiguration message. However, for third-party monitoring devices, since the target UE's reconfiguration message is encrypted, the target UE's context cannot be obtained. The true meaning of DCI0-1 can only be obtained through data detection. Therefore, how to more accurately parse the correct PISCH configuration from uncertain fields has become a pressing technical problem to be solved. Summary of the Invention

[0005] This application provides a method, apparatus, and storage medium for detecting the DCI0-1 content of PDCCH in a 5G system, so as to more accurately parse the correct PISCH configuration from uncertain fields.

[0018] The peak-to-average power ratio (PAPR) to be determined is calculated based on the PDP.

[0019] Further, calculating the peak-to-average ratio to be determined based on the PDP includes:

[0020] The maximum value of the PDP is determined as the PDP peak value, and the PDP peak value is multiplied by a preset threshold to determine the PDP threshold value;

[0021] If there is a value in the PDP threshold that is less than the PDP threshold, then calculate the first average value of all values ​​less than the PDP threshold, and divide the PDP peak value by the first average value to determine the peak-to-average ratio to be determined.

[0022] Furthermore, calculating the peak-to-average power ratio (PAPR) to be determined based on the PDP also includes:

[0023] If there is no value less than the PDP threshold in the PDP threshold, then calculate the second PDP average value of all values ​​in the PDP threshold except the PDP peak value;

[0024] Divide the peak value of the PDP by the average value of the second PDP to determine the peak-to-average ratio to be determined.

[0025] Furthermore, calculating the peak-to-average power ratio (PAPR) to be determined based on the PDP also includes:

[0026] The peak-to-average power ratio to be determined is determined based on the number of ports in the local PUSCH.

[0027] When the number of ports is greater than 1, the peak-to-average power ratio (PAPR) of the ports corresponding to the multiple ports is calculated.

[0058] This embodiment discloses a method, apparatus, and storage medium for content detection of DCI0-1 in a 5G system's PDCCH. The method includes: filtering out undetermined fields in the dedicated control information DCI0-1 of the Physical Downlink Control Channel (PDCCH) based on preset rules; determining a set of physical parameter configuration PUSCHs based on the undetermined fields; and calculating the peak-to-average power ratio (PAPR) of each undetermined PUSCH in the undetermined PUSCH set based on received uplink data to determine the target PUSCH.

[0059] Please see Figure 2 , Figure 2 This is a schematic flowchart illustrating a content detection method for DCI0-1 of PDCCH in a 5G system, provided in the second embodiment of this application. This content detection method for DCI0-1 of PDCCH in a 5G system can be applied to a server. It is used to determine the set of PUSCHs to be determined based on all fields to be determined, calculate the peak-to-average power ratio (PAPR) of each PUSCH in the PUSCH set based on the received context data, and determine the target PISCH based on the PAPR. This achieves more accurate parsing of the correct PISCH configuration in uncertain fields.

[0060] based on Figure 1 The illustrated embodiment, for example Figure 2 As shown, step S10 includes steps S101 to S102.

[0061] Step S101: Obtain the bit sequence to be determined corresponding to DCI0-1 after decoding in the PDCCH;

[0062] Step S102: Based on the bit sequence to be determined, determine at least one corresponding PUSCH to be determined, and determine all PUSCH to be determined as the set of PUSCH to be determined.

[0063] Specifically, a bit sequence is a sequence in which every bit of a binary number is either 0 or 1. In computer science, bit sequences are commonly used to represent binary data. The method for finding a bit sequence depends on the programming language used and the computer architecture. Here are some common methods:

[0064] 1. Using bitwise operations: Bitwise operators (such as bitwise AND, OR, XOR, etc.) can be used to obtain each bit in a bit sequence;

[0065] 2. Using loops: You can use loops to iterate through each bit of a binary number and convert it to 0 or 1;

[0066] 3. Using bit strings: Bit sequences can be represented using bit strings (also called byte sequences). A bit string is a sequence of consecutive 0s and 1s;

[0067] 4. Using bit sequences: Bit sequences can be used to represent bit sequences. A bit sequence is a sequence of consecutive 0s and 1s, with each bit representing one bit in a binary number.

[0068] This embodiment discloses a method, apparatus, and storage medium for content detection of DCI0-1 in a PDCCH in a 5G system. The method for content detection of DCI0-1 in a PDCCH in a 5G system includes obtaining the bit sequence to be determined corresponding to the decoded DCI0-1 in the PDCCH; determining at least one corresponding PUSCH to be determined based on the bit sequence to be determined, and determining all PUSCHs to be determined as the set of PUSCHs to be determined; and calculating the peak-to-average power ratio (PAPR) of each PUSCH in the set of PUSCHs to be determined based on received uplink data to determine the target PUSCH. Through the above method, this application determines the set of PUSCHs to be determined based on all fields to be determined, calculates the PPR of each PUSCH in the set based on received context data, and determines the target PUSCH based on the PPR, thus achieving more accurate parsing of the correct PUSCH configuration in uncertain fields.

[0069] Please see Figure 3 , Figure 3 This is a schematic flowchart illustrating a content detection method for DCI0-1 of PDCCH in a 5G system, provided in the third embodiment of this application. This content detection method for DCI0-1 of PDCCH in a 5G system can be applied to a server. It is used to determine the set of PUSCHs to be determined based on all fields to be determined, calculate the peak-to-average power ratio (PAPR) of each PUSCH in the PUSCH set based on the received context data, and determine the target PISCH based on the PAPR. This achieves more accurate parsing of the correct PISCH configuration in uncertain fields.

[0070] based on Figure 2 The illustrated embodiment, for example Figure 3 As shown, step S20 includes steps S201 to S202.

[0071] Step S201: Based on the uplink data, calculate the peak-to-average ratio (PAR) of each PUSCH to be determined, and sort the PARs according to a preset arrangement order.

[0072] Step S202: The PUSCH corresponding to the highest peak-to-average ratio to be determined is determined as the target PUSCH.

[0073] Specifically, the steps corresponding to this embodiment can be understood as follows:

[0074] (1) Obtain the dci0-1 bits after PDCCH decoding;

[0075] (2) Parse all possible PUSCH configuration sets for the uncertain fields (as shown in Table 2) based on the DCI0-1 bit sequence. For example, the meaning of a variable in these uncertain fields is determined once the number of bits for that variable is fixed. After exhaustively listing all possible combinations of the number of bits for each uncertain field, all PUSCH configurations are exhaustively listed. The configuration content includes: DMRS type, time domain location, frequency domain location, and port number;

[0076] (3) Based on the received data, calculate the peak-to-average ratio of each type of PUSCH configuration in the PUSCH configuration set;

[0077] (4) Select the PUSCH configuration corresponding to the maximum peak-to-average ratio as the real configuration.

[0078] based on Figure 3 In the illustrated embodiment, step S201 includes:

[0079] Obtain the local PUSCH and generate a local time-domain sequence based on the local PUSCH;

[0080] Based on the local time-domain sequence and the received bit sequence to be determined, a delayed power spectrum (PDP) is generated.

[0081] The peak-to-average power ratio (PAPR) to be determined is calculated based on the PDP.

[0082] Based on the above embodiments, in this embodiment, calculating the peak-to-average power ratio (PAPR) based on the PDP includes:

[0083] The maximum value of the PDP is determined as the PDP peak value, and the PDP peak value is multiplied by a preset threshold to determine the PDP threshold value;

[0084] If there is a value in the PDP threshold that is less than the PDP threshold, then calculate the first average value of all values ​​less than the PDP threshold, and divide the PDP peak value by the first average value to determine the peak-to-average ratio to be determined.

[0085] Furthermore, it also includes:

[0086] If there is no value less than the PDP threshold in the PDP threshold, then calculate the second PDP average value of all values ​​in the PDP threshold except the PDP peak value;

[0087] Divide the peak value of the PDP by the average value of the second PDP to determine the peak-to-average ratio to be determined.

[0088] Furthermore, it also includes:

[0089] The peak-to-average power ratio to be determined is determined based on the number of ports in the local PUSCH.

[0090] When the number of ports is greater than 1, the peak-to-average power ratio (PAPR) of the ports corresponding to the multiple ports is calculated.

[0091] Calculate the average port peak-to-average ratio (PAPR) of each port, and use the average port PAPR as the PAPR to be determined.

[0092] The peak-to-average power ratio (PAPR) calculation method used in this implementation is as follows:

[0093] (1) Generate a local time-domain sequence based on the current PUSCH configuration, such as the type of dmrs, time-domain position, frequency-domain position, and port number (if it is a multi-port system, then each port has its own local sequence).

[0094] (2) Perform sliding correlation calculation between the local sequence and the received sequence to obtain the power delay profile (PDP);

[0095] (3) Select the maximum value in the PDP as the peak value. Multiply the maximum peak value by 0.06 as the threshold value Thr, and use the average of all relevant values ​​less than the threshold value as the mean. Calculate the peak-to-average ratio (PAR) by dividing the maximum peak value by the mean. If there are no relevant values ​​less than the threshold value, use the average of all relevant values ​​except the maximum peak value as the mean, and then calculate the PAR.

[0096] (4) If there are multiple ports in the current configuration, the average peak-to-average ratio of the multiple ports is averaged to obtain the peak-to-average ratio of this configuration.

[0097] Based on all the above embodiments, in this embodiment, the set of PUSCHs to be determined includes the type, time-domain location, frequency-domain location, and port number of the demodulation reference signal DMRS.
