Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a frequency domain data processing method, device, electronic device and storage medium. Background Art

[0002] In the 5G (fifth-generation mobile communication technology) NR (New Radio) wireless communication system, the PUSCH (Physical Uplink Shared Channel) is a physical channel for uplink transmission used to carry service data and some control data. It is jointly implemented by the AAU (Active Antenna Unit) and the BBU (Building Baseband Unit). The AAU is primarily responsible for receiving time-domain signals and IR (Infrared) compression. IR compression refers to the compression of IR interface data. The IR interface refers to the interface directly connecting the BBU to the RRU (Remote Radio Unit) or AAU, connected by optical fiber. The BBU is primarily responsible for FFT (Fast Fourier Transform), demapping, and PUSCH channel detection. PUSCH data processing includes symbol-level processing, bit-level processing, and measurement processing.

[0003] Symbol-level processing mainly includes parameter calculation, channel estimation and equalization, such as Figure 1 As shown in Figure 1, the resource usage and implementation efficiency of this process will affect the performance of the entire system. To improve the accuracy of back-end data processing, it is generally necessary to group the PRBs (Physical Resource Blocks) within the entire system bandwidth before entering the PUSCH dimensionality reduction process. Dimensionality reduction, channel estimation, and equalization are performed separately within each group.

[0004] In the prior art, symbol-level processing is performed serially, see Figure 2 After receiving the scheduling message, PRB grouping is performed and the target parameters required for symbol-level processing of each PRB group are calculated. Then, after the frequency domain data arrives, the frequency domain data of each PRB group is processed sequentially in a serial simple loop processing manner. Therefore, the total processing time is the sum of the processing time of all PRB groups. The frequency domain data processing time is longer, which leads to higher communication delay.

[0059] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of this application.

[0060] In order to reduce the processing time of frequency domain data and reduce the communication delay, the embodiment of the present application provides a frequency domain data processing method, which is applied to an electronic device with multiple processor cores. Figure 3 , the method comprising:

[0061] S101: After receiving a scheduling message, divide the PRB into multiple PRB groups.

[0062] The frequency domain data processing method of the embodiment of the present application can be implemented by an electronic device having multiple processor cores. Specifically, the electronic device can be an AAU or a BBU, etc.

[0063] The processor core, also known as the processor core, is the most important component of the processor. It is generally made of single-crystal silicon using a certain production process. All calculations, acceptance / storage of commands, and data processing of the processor are performed by the core.

[0064] During symbol-level processing, after receiving a scheduling message, the PRBs are grouped to obtain PRB groups. In addition, target parameters of each PRB group can be calculated separately. Subsequently, for each PRB group, the target parameters of the PRB group are used for processing frequency domain data in the PRB group.

[0065] S102: Monitor whether the frequency domain data of each of the above PRB groups has arrived.

[0066] Each PRB group includes at least 4 PRBs, which are physical resources used by PRB to carry frequency domain data. The frequency domain data of each PRB group is monitored. Among them, PRB group is a concept in the frequency domain, and the frequency domain data of each PRB group arrives simultaneously in the time domain.

[0067] S103. If the frequency domain data arrives, the subtasks for processing the frequency domain data of the PRB group will be mounted to each processor core respectively according to the preset subtask mounting rules, and each processor core will be used to process the mounted subtasks in parallel, wherein the preset subtask mounting rules include: each type of subtask corresponds to a corresponding priority, for any PRB group, the subtask of the next priority of the PRB group will be mounted only after the subtask of the previous priority of the PRB group is processed.

[0068] Multiple processor cores of an electronic device have parallel processing capabilities. An electronic device having multiple processor cores can be a device having multiple processors or a device having a multi-core processor, all of which are within the scope of protection of this application. In one example, when the electronic device is a BBU, a BBUPOOLING (BBU device pooling) architecture can be used to implement parallel computing.

[0069] In the embodiment of the present application, the processing of frequency domain data in each PRB group is divided into multiple types of subtasks. The specific types of subtasks can be divided according to actual conditions. In order to reduce the situation where the subtask processing time varies greatly due to the large difference in factor task size, in one example, when using the zero forcing algorithm, the subtasks may include a channel estimation subtask and an equalization calculation subtask; when using MMSE (Minimum mean-square error), the subtasks may include a channel estimation subtask, an RUU calculation subtask, and an equalization calculation subtask, where RUU refers to the autocorrelation matrix of the channel frequency response under the MMSE algorithm, thereby realizing the splitting of subtasks according to appropriate subtask processing time and priority, effectively reducing the problem of uneven workload on different processor cores.

[0070] In one example, a processor core may be used to establish a subtask processing process to implement subtask processing, for example, a channel estimation subtask processing process may be established for a channel estimation subtask, an RUU calculation subtask processing process may be established for an RUU calculation subtask, an equalization calculation subtask processing process may be established for an equalization calculation subtask, and the like.

[0071] Each type of subtask corresponds to a corresponding priority. For any PRB group, the subtask of the next priority level will be mounted only after the subtask of the previous priority level is completed. For example, for any PRB group, the RUU calculation subtask and equalization calculation subtask of the PRB group will be mounted only after the channel estimation subtask of the PRB group is completed. The subtasks in different PRB groups are processed in the same order, so the order of mounting subtasks in different PRB groups does not affect each other.

[0072] The resource occupancy rate and implementation efficiency of the symbol-level processing process in the PUSCH channel will affect the performance of the entire wireless system. In the embodiment of the present application, the frequency domain data processing process of each PRB group is split into a processing process of multiple subtasks, and multiple processor cores are used to process each subtask separately. The subtasks in different PRB groups can be processed in parallel, and the symbol-level processing is changed from serial processing to parallel processing. It can reduce the overall processing time of all PRB groups, reduce the communication delay, and effectively utilize system resources, reduce the waste of time and memory, improve the processing efficiency of the PUSCH module, and improve the resource utilization of the entire system.

[0073] For different cell standards and frame structures, symbol-level task mounting includes two modes: time division duplex (TDD) and frequency division duplex (FDD). When using TDD, to save processing time, after receiving the frequency domain data handshake flag, the pre-pilot (i.e., the first column of pilot) channel estimation subtask is mounted on the first handshake flag symbol (generally symbol 3), and the other pilot channel estimation subtasks and equalization calculation subtasks are mounted on the second handshake flag symbol (generally symbol 13). For FDD, since the uplink time slots are adjacent, there is no point in pre-processing them. Therefore, the pre-pilot channel estimation subtask is mounted on the second handshake flag symbol. After the pre-pilot channel estimation subtask is executed, the remaining tasks are automatically mounted according to the task mounting rules and priority.

[0074] In a possible implementation, the subtasks for processing the PRB group frequency domain data are mounted to each processor core according to a preset subtask mounting rule, including:

[0075] Step 1: In the case of time division duplex mounting mode, for the PRB group of frequency domain data arriving, after receiving the first handshake flag symbol, the pre-pilot channel estimation subtask of the PRB group is mounted to the corresponding processor core according to the preset load balancing rule;

[0076] Step 2: When there are other pilots besides the pre-pilot in the PRB group, after receiving the second handshake flag symbol, determine whether the pre-pilot channel estimation subtask of the PRB group is completed. If completed, the other pilot channel estimation subtasks of the other pilots are mounted to the corresponding processor core according to the preset load balancing rule; determine whether the other pilot channel estimation subtasks of the PRB group are completed. If so, the balance calculation subtask of the PRB group is mounted to the corresponding processor core according to the preset load balancing rule; and / or

[0077] Step three, when there are no other pilots except the pre-pilot in the PRB group, after receiving the second handshake flag symbol, determine whether the pre-pilot channel estimation subtask of the PRB group is completed. If completed, the other subtasks of the PRB group are mounted to the corresponding processor core according to the preset load balancing rules, wherein the above-mentioned other subtasks include the balancing calculation subtask, or the above-mentioned other subtasks include the balancing calculation subtask and the RUU calculation subtask.

[0078] In one example, when the minimum mean square error algorithm is adopted, the other subtasks include the equalization calculation subtask and the RUU calculation subtask; when the zero forcing algorithm is adopted, the other subtasks include the equalization calculation subtask.

[0079] In a possible implementation, the subtasks for processing the PRB group frequency domain data are mounted to each processor core according to a preset subtask mounting rule, including:

[0080] Step 1: In the case of frequency division duplex mounting mode, for the PRB group of frequency domain data arriving, after receiving the second handshake flag symbol, the pre-pilot channel estimation subtask of the PRB group is mounted to the corresponding processor core according to the preset load balancing rule;

[0081] Step 2: When there are other pilots besides the pre-pilot in the PRB group, determine whether the pre-pilot channel estimation subtask of the PRB group is completed. If completed, mount the other pilot channel estimation subtasks of the other pilots to the corresponding processor core according to the preset load balancing rule; determine whether the other pilot channel estimation subtasks of the PRB group are completed. If so, mount the balance calculation subtask of the PRB group to the corresponding processor core according to the preset load balancing rule; and / or

[0082] Step three, when there are no other pilots except the pre-pilot in the PRB group, determine whether the pre-pilot channel estimation subtask of the PRB group is completed; if completed, mount the other subtasks of the PRB group to the corresponding processor core according to the preset load balancing rules, wherein the other subtasks include the balancing calculation subtask, or the other subtasks include the balancing calculation subtask and the RUU calculation subtask.

[0083] In one example, when the minimum mean square error algorithm is adopted, the other subtasks include the equalization calculation subtask and the RUU calculation subtask; when the zero forcing algorithm is adopted, the other subtasks include the equalization calculation subtask.

[0084] The preset load balancing rules can be set according to actual conditions. For example, subtasks can be mounted to each processor core in turn in a round-robin manner, or an idle processor core or a processor core with the least load can be selected as the processor core for mounting the current subtask according to the actual load of each processor core. In one example, the preset load balancing rule can be: before mounting a subtask, traverse each processor core in turn in a preset order until an idle processor core is found, and then mount the subtask on the idle processor core; if no idle processor core is found after traversing all processor cores, traverse again until the traversal time threshold is reached. If the traversal time threshold is exceeded, the mounting is determined to have failed.

[0085] For different balancing methods, the types and mounting orders of subtasks are also different, for example Figure 4 As shown, under the condition that the preceding task is completed, for the zero-forcing algorithm, the next column of pilot channel estimation subtask or equalization calculation subtask is directly mounted; for the minimum mean square error algorithm, it is necessary to determine whether the number of PRBs occupied by the current PRB group is greater than the preset value. If it is greater than the preset value, only the preceding pilot is used to calculate the RUU, and the RUU calculation subtask can be mounted immediately and calculated. Otherwise, all pilots need to be used to calculate the RUU. The mounting and execution of the RUU calculation subtask need to be performed after the last column of pilot channel estimation subtask is completed.

[0086] In a possible implementation, the determining whether the pre-pilot channel estimation subtask of the PRB group is completed, and if completed, mounting the other pilot channel estimation subtasks of the other pilots to the corresponding processor core according to a preset load balancing rule, includes:

[0087] In step A, when a zero-forcing algorithm is used, it is determined whether the pre-pilot channel estimation subtask for the PRB group is completed. If so, step B is executed. In one example, if not, step A is executed again after waiting for a preset time period. In one example, if the pre-pilot channel estimation subtask for the PRB group is not completed within a specified number of consecutive preset time periods, the current process is abandoned and an error message is sent.

[0088] Step B: determine whether the pilot channel estimation subtasks of each column of the PRB group are all mounted and completed. If not, execute step C.

[0089] Step C: mount the next column pilot channel estimation subtask of the PRB group to the corresponding processor core according to the preset load balancing rule, and return to execute step B until all columns pilot channel estimation subtasks of the PRB group are mounted.

[0090] The pilot channel estimation subtasks can be mounted sequentially from the first column to the Nth column. In this case, if the next pilot column is the i-th column, the subtask with the highest priority before the next pilot channel estimation subtask is the i-1-th column pilot channel estimation subtask. In some possible scenarios, such as when using the minimum mean square error algorithm, the subtask with the highest priority before the next pilot channel estimation subtask may also be the RUU subtask.

[0091] In step D, the next column pilot channel estimation subtask of the PRB group is mounted to the processor core corresponding to the corresponding subtask according to the preset load balancing rule, and the process returns to step B until all columns pilot channel estimation subtasks of the PRB group are mounted.

If so, execute steps b1 and b2. For example, step b1 can be executed first and then step b2, or steps b1 and b2 can be executed simultaneously. In one example, if not, wait for a preset time length and then execute step a1 again. In one example, if the pre-pilot channel estimation subtask of the PRB group is not completed within a specified number of preset time lengths, the current processing is abandoned and an error message is sent. The preset value can be customized according to actual conditions, for example, it can be set to 8.

[0094] Step b1: Mount the RUU calculation subtask of the PRB group to the corresponding processor core according to the preset load balancing rule.

[0095] Step b2: determine whether the pilot channel estimation subtasks of each column of the PRB group are all mounted and completed. If not, execute step b3.

[0096] In step b3, it is determined whether the subtask of the previous priority level of the next pilot channel estimation subtask is completed. If so, step b4 is executed. In one example, if not, step b4 is executed again after waiting for a preset time period. In one example, if the subtask of the previous priority level is not completed within a specified number of consecutive preset time periods, the current process is abandoned and an error message is sent.

[0097] Step b4: mount the next column pilot channel estimation subtask of the PRB group to the corresponding processor core according to the preset load balancing rule, and return to step b2 until all columns pilot channel estimation subtasks of the PRB group are mounted.

[0098] In a possible implementation, the determining whether the pre-pilot channel estimation subtask of the PRB group is completed, and if completed, mounting the other pilot channel estimation subtasks of the other pilots to the corresponding processor core according to a preset load balancing rule, includes:

[0099] In step a2, if the minimum mean square error algorithm is used and the number of PRBs in the PRB group is not greater than a preset value, determine whether the pre-pilot channel estimation subtask for the PRB group is completed. If so, execute step c1. In one example, if not, wait for a preset time period and then execute step a2 again. In one example, if the pre-pilot channel estimation subtask for the PRB group is not completed within a specified number of consecutive preset time periods, abandon the current process and send an error message.

[0100] Step c1, determining whether all pilot channel estimation subtasks of the PRB group are completed, if not, executing step c2, if yes, executing step c4.

[0101] In step c2, it is determined whether the subtask of the previous priority level of the next pilot channel estimation subtask is completed. If so, step c3 is executed. In one example, if not, step c2 is executed again after waiting for a preset time period. In another example, if the subtask of the previous priority level is not completed within a specified number of consecutive preset time periods, the current process is abandoned and an error message is sent.

[0102] Step c3: mount the next column of pilot channel estimation subtasks of the PRB group to the corresponding processor core according to the preset load balancing rule, and return to step c1.

[0103] Step c4: When the pilot channel estimation subtasks of each column of the PRB group are completed, the RUU calculation subtask of the PRB group is mounted to the corresponding processor core according to the preset load balancing rule.

[0104] In the embodiment of the present application, the mounting order of subtasks in different situations is given, which can reduce the problem of unbalanced workload of different processor cores, fully utilize the advantages of multiple processor cores, reduce the overall processing time of all PRB groups, reduce communication latency, and effectively utilize system resources, reduce time and memory waste, improve the processing efficiency of the PUSCH module, and improve the resource utilization of the entire system.

[0105] When the minimum mean square error algorithm is used, the other subtasks include the equalization calculation subtask and the RUU calculation subtask; when the zero forcing algorithm is used, the other subtasks include the equalization calculation subtask. In one possible implementation, the above-mentioned determination of whether the pre-pilot channel estimation subtask of the PRB group is completed, and if completed, the other subtasks of the PRB group are mounted to the corresponding processor core according to the preset load balancing rules, including:

[0106] In the case of adopting the minimum mean square error algorithm, determining whether the pre-pilot channel estimation subtask of the PRB group is completed, and if completed, mounting the RUU calculation subtask of the PRB group to the corresponding processor core according to the preset load balancing rule; after the RUU calculation subtask of the PRB group is completed, mounting the balancing calculation subtask of the PRB group to the corresponding processor core according to the preset load balancing rule; and / or

[0107] When the zero forcing algorithm is adopted, it is determined whether the pre-pilot channel estimation subtask of the PRB group is completed. If completed, the balancing calculation subtask of the PRB group is mounted to the corresponding processor core according to the preset load balancing rule.

[0108] The embodiment of the present application also provides a frequency domain data processing method applied to a BBU, which adopts a BBUPOOLING architecture and includes a multi-core processor. Figure 5 , the method comprising:

[0109] Step 1: Receive and process the scheduling message.

[0110] Step 2: divide the PRB into multiple PRB groups.

[0111] The number of PRB groups is PRB_GROUP_NUM.

[0112] Step 3: Calculate the target parameters of each PRB group respectively.

[0113] For any PRB group, the target parameters of the PRB group include parameters required for channel estimation and equalization calculation of frequency domain data of the PRB group, and may also include parameters required for calculating RUU of the PRB group.

[0114] Step 4: Determine whether the frequency domain data of each PRB group has arrived.

[0115] Step 5: Subtasks are mounted and processed in parallel.

[0116] For the PRB grouping of frequency domain data arriving, the subtask for processing the frequency domain data of the PRB grouping is mounted to each processor core according to the preset subtask mounting rule, and each processor core is used to process the mounted subtask in parallel;

[0117] Step 6: Determine whether all subtasks of the PRB grouping are completed. If not, return to step 5. If so, end this process.

[0118] The splitting and mounting of tasks for parallel processing can fully utilize the advantages of multi-core processors and avoid workload imbalance. However, this parallel processing also requires reasonable setting of task processing time to avoid tasks that are too large and take too long to execute, thereby affecting overall efficiency. In the embodiment of the present application, the subtasks of the PUSCH symbol-level processing part are divided into: channel estimation subtask, RUU calculation subtask, and equalization calculation subtask. Their priorities are sequentially increased to ensure that the tasks of each PRB group are executed in sequence.

[0119] Subtasks are mounted differently for different cell standards and frame structures, depending on time division duplex (TDD) or frequency division duplex (FDD). In TDD mode, to save processing time, after receiving the frequency domain data handshake flag, the first column, the pre-pilot channel estimation task, is mounted at symbol 3, and other pilot channel estimation tasks and equalization tasks are mounted at symbol 13. In FDD mode, because uplink time slots are closely spaced, pre-processing is meaningless. Therefore, only the pre-pilot channel estimation subtask is mounted at symbol 13. After the pre-pilot channel estimation subtask completes, the remaining subtasks are mounted according to the subtask mounting rules and priority, and no subtasks are mounted at symbol 3.

[0120] In the embodiment of the present application, not only the function calculation of PUSCH symbol-level processing is split into tasks according to appropriate duration and priority, but also a set of detailed subtask mounting rules are formulated. According to different system configurations, the conditions for task mounting and execution are set, such as Figure 6As shown, the frequency domain data handshake flag arrives at symbol 3 and symbol 13. The task mounting of both TDD (time division duplex) and FDD (frequency division duplex) scenarios starts after receiving the frequency domain data handshake flag. The pre-pilot channel estimation subtask of TDD is mounted when the handshake flag of symbol 3 arrives, and the pre-pilot task of FDD is mounted when the handshake flag of symbol 13 arrives. Except for the first column of pilots, i.e., the pre-pilot, both TDD and FDD scenarios need to determine whether the pre-task is completed when mounting other tasks. Only when the pre-task is completed can the task be mounted, otherwise it will exit directly. In addition, in the TDD scenario, when mounting CHE1 (CHE1 represents the channel estimation subtask for other column pilots except the pre-pilot channel estimation subtask), RUU calculation subtask, and EQ (EQ is the abbreviation of Equalization, which means equalization in Chinese and is used to represent the equalization calculation subtask) in addition to the pre-pilot, it is also necessary to determine whether the handshake flag of symbol 13 has arrived. The task is mounted and executed only when the frequency domain data handshake flag of symbol 13 has arrived. Otherwise, it exits directly.

[0121] For different balancing methods, the types and mounts of tasks are also different. Figure 4 As shown in the figure: under the condition that the preceding task is completed, for the ZF (Zero Foring) algorithm, the channel estimation subtask CHE1 or the equalization calculation subtask EQ of the next pilot column is directly mounted; for the MMSE algorithm, it is necessary to additionally determine whether the number of PRBs occupied by the current PRB group is greater than 8. If it is greater than 8, only the preceding pilot is used to calculate the RUU, and the RUU calculation subtask can be mounted and calculated immediately. Otherwise, all pilots need to be used to calculate the RUU. The RUU calculation subtask is mounted and executed after the last pilot column completes the CHE1 task.

[0122] The number of CHE1 subtasks is related to the number of additional pilots. The mounting timing of the RUU calculation subtask is related to the number of PRBs in the current PRB group. The main difference between the mounting tasks in TDD and FDD scenarios lies in the mounting conditions of CHE1 and EQ tasks: TDD requires the completion of the predecessor task and the arrival of the symbol 13 handshake flag, while FDD only requires the completion of the predecessor task.

[0123] The present application also provides a frequency domain data processing device, which is applied to an electronic device having multiple processor cores. Figure 7 , the device comprises:
