Firstly, the parameters to be processed for generating sounding reference signals of multiple terminals are obtained, and all the parameters to be processed are classified and processed to obtain the common parameters of all terminals. parameters and the private parameters of each terminal, and then process the public parameters to obtain the first target parameter, then obtain the information to be sent in the current transmission time slot according to the first target parameter and the private parameter, and then generate the current transmission time slot according to the information to be sent Sounding reference signal.

Therefore, the processing time and processing resources for the sounding reference signal can be reduced, and the efficiency of large-capacity testing for the sounding reference signal can be improved.

The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

As shown in FIG. 1 , FIG. 1 is a schematic diagram of a system architecture for executing a signal processing method provided by an embodiment of the present invention. In the example of FIG. 1 , the system architecture includes a testing device 110 , a base station 120 and a plurality of terminals 130 . Wherein, the test device 110 is connected in communication with these terminals 130, and can acquire the parameters to be processed for generating SRS signals sent by these terminals 130, and process these parameters to be processed to generate SRS signals, and then send the SRS signals to the base station 120, enabling the base station 120 to use the SRS signal to estimate uplink channel quality or downlink channel quality in different frequency bands.

The system architecture and application scenarios described in the embodiments of the present invention are to illustrate the technical solutions of the embodiments of the present invention more clearly, and do not constitute limitations on the technical solutions provided by the embodiments of the present invention. Those skilled in the art know that with the system architecture evolution and the emergence of new application scenarios, the technical solutions provided by the embodiments of the present invention are also applicable to similar technical problems.

Those skilled in the art can understand that the system architecture shown in Figure 1 does not constitute a limitation to the embodiment of the present invention, and may include more or less components than those shown in the illustration, or combine some components, or different components layout.

Based on the above system architecture, various embodiments of the signal processing method of the present invention are proposed below.

Referring to FIG. 2, FIG. 2 is a flowchart of a signal processing method provided by an embodiment of the present invention. The signal processing method is applied to a test device, such as the test device 110 in the system architecture shown in FIG. 1. The signal The processing method includes but not limited to step S110, step S120, step S130, step S140 and step S150.

Step S110, acquiring parameters to be processed of multiple terminals.

It should be noted that the parameters to be processed obtained from multiple terminals are parameters used to generate SRS signals, such as SRS ID, frame number, time slot number, whether group hopping sequence hopping is enabled, cell-specific SRS bandwidth The configuration parameters (Csrs), terminal-specific bandwidth configuration parameters (Bsrs), etc. are not specifically limited in this embodiment.

It should be noted that when performing a large-capacity test for SRS signals, a large number of terminals need to be used to send SRS signals to the base station. The terminals can actively use the parameters to be processed to generate SRS signals according to the configuration information of the base station and send them to the base station, or they can After receiving the request information from the base station, the SRS signal is generated using the parameters to be processed and sent to the base station. However, in the current test scheme, each terminal needs to process the SRS signal independently, resulting in a waste of processing time and processing resources. affect the efficiency of testing. In order to solve this problem, in this step, the test device first obtains the parameters to be processed of multiple terminals, and then processes these parameters to be processed uniformly in subsequent steps, without the need for each terminal to independently process the SRS signal, thereby improving the performance of the target terminal. Efficiency of bulk testing of SRS signals.

Step S120, performing classification processing on all parameters to be processed to obtain public parameters of all terminals and private parameters of each terminal.

It should be noted that the public parameters refer to the same parameters of each terminal in the time domain position of the current SRS signal or the parameters used for the time domain link after processing, such as frame number, time slot number, and number of symbols contained in the time slot parameters such as whether group hopping sequence hopping is enabled, cell ID, and SRS rotation flag for time-domain links; private parameters refer to different parameters of each terminal, such as radio network temporary identity (Radio Network Tempory Identity , RNTI), cell-specific SRS bandwidth configuration parameters, terminal-specific bandwidth configuration parameters, SRS ID and other parameters.

It should be noted that among the parameters to be processed used by each terminal to generate the SRS signal, there are some common parameters and parameters unique to each terminal. If each terminal independently generates the SRS signal according to the parameters to be processed, these Repeated processing of common parameters will result in waste of processing time and processing resources, thereby affecting test efficiency. In order to solve this problem, in this step, after performing step S110 to obtain the parameters to be processed of each terminal, all the parameters to be processed can be classified and processed to obtain the public parameters of all terminals and the private parameters of each terminal, so as to facilitate subsequent steps The public parameters of all terminals and the private parameters of each terminal can be processed separately, so that the public parameters of all terminals are only processed once, which reduces the repeated processing of public parameters by each terminal and saves the cost of processing the public parameters for each terminal The processing time and processing resources can improve the efficiency of large-capacity testing of SRS signals.

In step S130, the public parameters are processed to obtain the first target parameters.

In this step, since the public parameters of all terminals and the private parameters of each terminal are obtained in step S120, the public parameters can be processed first to obtain the first target parameter, so that subsequent steps can be based on the first target parameter and each terminal The SRS signal of each terminal is obtained by calculating the private parameters of each terminal, which saves the processing time and resources consumed by each terminal to obtain the first target parameter, and thus can improve the efficiency of large-capacity testing for SRS signals.

It should be noted that there may be many different implementation manners for obtaining the first target parameter by processing the public parameters, and a proper selection may be made according to actual application conditions, which is not specifically limited here. For example, the public parameters can be cached so that subsequent steps can read the cached public parameters to generate the SRS signal. In this case, the public parameters are the first target parameters; Obtain the intermediate parameters used to generate the SRS signal, such as according to the public parameters such as the time slot number and the number of symbols contained in the time slot, calculate the intermediate parameters of the group number, so that the subsequent steps can generate the SRS signal according to the intermediate parameters of the group number, in In this case, the intermediate parameter of the group number is the first target parameter.

Step S140, according to the first target parameter and the private parameter, the information to be sent in the current transmission time slot is obtained.

In this step, since the public parameters of all terminals and the private parameters of each terminal are obtained in step S120, and the first target parameter is obtained according to the public parameters in step S130, it can be obtained according to the first target parameter and private parameters The to-be-sent information of the current transmission time slot, so that the subsequent steps can generate the SRS signal of the current transmission time slot according to the to-be-sent information, and then the large-capacity test for the SRS signal between the test device and the base station can be realized.

It should be noted that both the first target parameter and the private parameter are intermediate parameters used to generate the SRS signal. Therefore, in a feasible implementation manner, after obtaining the first target parameter and the private parameters of each terminal, you can first According to the first target parameter and the private parameters of each terminal, calculate the SRS sequence of each terminal, and then map the SRS sequence of each terminal to the corresponding position in the current transmission time slot to obtain the information to be sent in the current transmission time slot, so that The subsequent step may generate the SRS signal of the current transmission time slot according to the information to be sent. In addition, in another feasible implementation manner, after the first target parameter and the private parameters of each terminal are obtained, the SRS sequence of the terminal may be calculated according to the first target parameter and the private parameter of one of the terminals, and Mapping the SRS sequence of the terminal to the corresponding position in the current transmission time slot, and then calculating the SRS sequence of the other terminal according to the first target parameter and the private parameter of the other terminal, and calculating the SRS sequence of the other terminal Mapped to the corresponding position in the current transmission time slot, and so on, and finally the information to be sent in the current transmission time slot can be obtained, so that the subsequent steps can generate the SRS signal of the current transmission time slot according to the information to be sent. Since the information to be sent and the subsequently generated SRS signal are integrated signals including relevant parameters of each terminal, the efficiency of sending signals can be improved.

Step S150, generating the SRS signal of the current transmission time slot according to the information to be transmitted.

In this step, since the information to be transmitted of the current transmission time slot is obtained in step S140, the SRS signal of the current transmission time slot can be generated according to the information to be transmitted, so as to realize the large-capacity test for the SRS signal between the test device and the base station .

It should be noted that the SRS signal of the current transmission time slot can be generated according to the information to be sent in different implementation manners. For example, when the information to be sent is frequency domain information, the information to be sent can be converted into time domain information, and then the Radio frequency modulation processing is performed on the time domain information to obtain an SRS signal; for another example, when the information to be sent is time domain information, the radio frequency modulation processing may be directly performed on the information to be sent to obtain an SRS signal.

In this embodiment, by adopting the signal processing method including the above steps S110, S120, S130, S140, and S150, the parameters to be processed of multiple terminals are first classified and processed to obtain the public parameters of all terminals and the parameters of each terminal. private parameters, and then process the public parameters to obtain the first target parameters, and then use the first target parameters as a basis, combined with the private parameters of each terminal to obtain the information to be sent in the current transmission time slot, that is, when generating the waiting information of each terminal When sending information, there is no need to process public parameters, so the processing time and processing resources for public parameters can be saved, thereby reducing the processing time and processing resources for SRS signals in subsequent steps, and improving the large-capacity test for SRS signals s efficiency.

Referring to FIG. 3 , an embodiment of the present invention, step S140 is further described, and step S140 may include but not limited to the following steps:

Step S141, selecting among multiple terminals, and obtaining the frequency domain sequence information of the currently selected terminal according to the private parameters of the currently selected terminal and the first target parameter;

Step S142, mapping the frequency domain sequence information of the currently selected terminal to the corresponding frequency domain resource position to obtain target frequency domain data;

Step S143, counting the number of selected terminals;

Step S144, according to the number of selected terminals, the total number of terminals supported by the current transmission time slot, and the target frequency domain data, the information to be sent in the current transmission time slot is obtained.

It should be noted that a transmission time slot may include multiple resource blocks, and in order to increase the resource utilization efficiency of resource blocks, SRS information of multiple terminals may be carried in multiple resource blocks of one transmission time slot, so , in the process of obtaining the information to be sent in the current transmission time slot according to the first target parameter and the private parameter, it is possible to select among multiple terminals first, and obtain the currently selected terminal according to the private parameter of the currently selected terminal and the first target parameter The frequency domain sequence information of the terminal, and then map the frequency domain sequence information of the currently selected terminal to the corresponding frequency domain resource position to obtain the target frequency domain data, and then according to the number of selected terminals and the current transmission slot supported The total number of terminals and the target frequency domain data are used to obtain the information to be sent in the current transmission slot. For example, if the number of selected terminals does not reach the total number of terminals supported by the current transmission slot, it means that the current transmission slot can also support more The frequency domain sequence information of many terminals, so the rest of the terminals can continue to be selected, and the frequency domain sequence information of the selected terminal is mapped to the corresponding frequency domain resource position, until the number of selected terminals reaches the current transmission slot support The total number of terminals; if the number of selected terminals reaches the total number of terminals supported by the current transmission slot, it means that there are no more resource blocks in the current transmission slot that can carry the frequency domain sequence information of the terminal, so the remaining The frequency domain sequence information of the terminal is mapped to the corresponding frequency domain resource position.

In this embodiment, after the public parameters are processed to obtain the first target parameters, by combining the first target parameters with the private parameters of each terminal, the frequency domain sequence information of the terminals is calculated one by one and the frequency domain sequence information is mapped to the corresponding The frequency domain resource position enables the calculated frequency domain sequence information to be mapped to the corresponding frequency domain resource position, thereby improving data processing efficiency.

Referring to Figure 4, an embodiment of the present invention, step S144 is further described, step S144 may include but not limited to the following steps:

Step S1441, when the number of selected terminals is less than the total number of terminals supported by the current transmission slot, select again among the remaining terminals, and obtain the reselected terminal according to the private parameters of the reselected terminal and the first target parameter The frequency domain sequence information of ;

Step S1442, map the frequency domain sequence information of the reselected terminal to the corresponding frequency domain resource position, and update the target frequency domain data until the number of selected terminals is equal to the total number of terminals supported by the current transmission slot;

Step S1443, determining the finally obtained target frequency domain data as information to be sent in the current transmission time slot.

It should be noted that, when step S144 is executed, if the number of selected terminals is less than the total number of terminals supported by the current transmission time slot, it means that the current transmission time slot can also support frequency domain sequence information of more terminals, then you can Select again among the remaining terminals, obtain the frequency domain sequence information of the reselected terminal according to the private parameters of the reselected terminal and the first target parameter, and then map the frequency domain sequence information of the reselected terminal to the corresponding frequency The target frequency domain data is updated until the number of selected terminals is equal to the total number of terminals supported by the current transmission time slot. When the number of selected terminals is equal to the total number of terminals supported by the current transmission slot, it means that there are no more resource blocks in the current transmission slot that can carry the frequency domain sequence information of the terminal, so the frequency domain sequence information of the remaining terminals is no longer The sequence information is mapped to the corresponding frequency domain resource position. At this time, the finally obtained target frequency domain data can be determined as the information to be sent in the current transmission time slot.

In addition, in another embodiment, after performing step S143 to count the number of selected terminals, if the number of selected terminals is equal to the total number of terminals supported by the current transmission time slot, it means that the target frequency obtained in step S142 The domain data already occupies the resource blocks of the current transmission time slot, so the target frequency domain data can be directly determined as the information to be sent in the current transmission time slot.

In a feasible implementation, the counter can be started to count the number of selected terminals. Whenever a terminal is selected and the frequency domain sequence information of the selected terminal is mapped to the corresponding frequency domain resource position, the value of the counter will increase by 1 , when the value of the counter changes, the value of the counter will be compared with the total number of terminals supported by the current transmission slot, if the value of the counter is less than the total number of terminals supported by the current transmission slot, then among the remaining terminals Select again, obtain the frequency-domain sequence information of the re-selected terminal according to the private parameters of the re-selected terminal and the first target parameter, and then map the frequency-domain sequence information of the re-selected terminal to the corresponding frequency-domain resource position, and update Target frequency domain data; if the value of the counter is equal to the total number of terminals supported by the current transmission time slot, then determine the finally obtained target frequency domain data as the information to be sent in the current transmission time slot.

It should be noted that, in an optional implementation manner, when the number of selected terminals is equal to the total number of terminals supported by the current transmission slot, the number of selected terminals may be cleared, or That is to say, the value of the counter can be cleared, so that the counter after clearing can be used to count the number of selected terminals in the next transmission time slot, and then it can conveniently determine the resource block of the next transmission time slot whether it is fully utilized.

Referring to FIG. 5 , an embodiment of the present invention, step S141 is further described, and step S141 may include but not limited to the following steps:

Step S1411, according to the private parameters of the currently selected terminal and the first target parameter, calculate the second target parameter of the currently selected terminal;

Step S1412: Generate frequency domain sequence information of the currently selected terminal according to the second target parameter.

It should be noted that the frequency domain sequence information is a data sequence used to obtain the SRS signal, and the second target parameter is an SRS parameter corresponding to the terminal and used to generate the frequency domain sequence information. There may be multiple second target parameters of the terminal, and some examples are used below for specific description.

Example one:

Assuming that the public parameters include the time slot number, the number of symbols contained in the time slot, and the position of the transmitted symbol of the SRS signal, then it is possible to calculate the group number u (ie, the second target parameter) according to the public parameters and the following formula (1). The group number intermediate parameter of (i.e. the first target parameter):

In formula (1), is the slot number; /> is the number of symbols contained in the time slot; l ₀ +l' is the position of the transmitted symbol of the SRS signal; l ₀ is the position of the first Orthogonal Frequency Division Multiplexing (OFDM) symbol, and l' is l The offset of ₀ , the value of l ₀ +l' traverses from 8 to 13; c(*) is a pseudo-random sequence function, used to generate a pseudo-random sequence. According to the above formula (1), it can be seen that the calculated intermediate parameter of the group number /> There are also 6 values correspondingly.

After calculating according to the above formula (1), the first target parameter Afterwards, according to the private parameters of the currently selected terminal and the first target parameter/> The second target parameter u of the currently selected terminal is calculated by using the following formula (2):

In formula (2), SRS ID of the currently selected terminal; /> It is a private parameter of the currently selected terminal.

Example two:

Assuming that the public parameters include the time slot number, the number of symbols contained in the time slot, the position of the SRS signal transmission symbol, the length of the SRS sequence, and the number of subcarriers in the resource block, then these public parameters can be cached first. At this time, The cached public parameter is the first target parameter. After obtaining the first target parameter, according to the private parameters of the currently selected terminal and the first target parameter, the following formula (3) can be used to calculate the serial number v (i.e. the second target parameter) in the group of the currently selected terminal:

In formula (3), is the slot number; /> is the number of symbols contained in the time slot; l ₀ +l' is the position of the transmitted symbol of the SRS signal; l ₀ is the position of the first OFDM symbol, l' is the offset of l ₀ , and the value of l ₀ +l' is The value is traversed from 8 to 13; c(*) is a pseudo-random sequence function, used to generate a pseudo-random sequence; /> is the SRS sequence length; /> is the number of subcarriers in the resource block. According to the formula (3), when /> greater than /> When , the value of the sequence number v in the group is /> Otherwise, the sequence number v in the group takes the value 0.

Example three:

Assuming that the public parameters include the sending code score, the maximum sending code score and the number of antenna ports for transmitting SRS signals, then the cyclic shift value used to generate the antenna port Pi corresponding to can be calculated according to the public parameters and the following formula (4): The cyclic shift intermediate parameter of α _i (ie, the second target parameter) (i.e. the first target parameter):

In formula (4), Score value for send code; /> is the maximum sent code score; /> is the number of antenna ports for transmitting SRS signals; Pi is the serial number of the antenna port.

After calculating according to the above formula (4), the first target parameter Afterwards, according to the private parameters of the currently selected terminal and the first target parameter/> The second target parameter α _i of the currently selected terminal is calculated by using the following formula (5):

In formula (2), since the first target parameter has been calculated in advance Therefore, it can be directly based on the first objective parameter /> and public parameters /> Calculate the second target parameter α _i of each terminal, thereby improving the calculation efficiency and saving the calculation of the first target parameter by each terminal/> The processing time and processing resources required.

Referring to FIG. 6, an embodiment of the present invention, step S150 is further described, and step S150 may include but not limited to the following steps:

Step S151, performing data domain conversion processing on the information to be sent to obtain target time domain information;

Step S152, performing data conversion processing on the target time domain information to obtain the SRS signal of the current transmission time slot.

It should be noted that the information to be transmitted of the current transmission time slot obtained in step S140 is frequency domain data, and the SRS signal sent to the base station is time domain data. Therefore, after obtaining the information to be transmitted of the current transmission time slot After that, it is necessary to perform data domain conversion processing on the information to be sent to obtain the target time domain information, and then perform data conversion processing on the target time domain information to obtain the SRS signal of the current transmission time slot, so that the subsequent steps can convert the SRS signal of the current transmission time slot The signal is sent to the base station to realize the large-capacity test of the SRS signal between the test device and the base station.
