Description

Method and device for measuring frame error rate Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method and device for measuring a frame error rate. Background Art

[0002] In the performance testing of communications equipment, receiver performance is a key technical indicator for measuring device performance, typically measured by the frame error rate (FER). The FER refers to the average probability of an information frame transmission error during data transmission.

[0003] Traditional 2G / 3G / 4G mobile broadband (MBB) services generally require a frame error rate of FER = 10 -1 ~10 -2 However, with the emergence of scenarios with higher latency requirements, such as 5G ultra reliable and low latency communications (URLLC), higher requirements are placed on the frame error rate index (e.g. FER=10 -6 ~10 -8 This poses a greater challenge to measuring the device's frame error rate, resulting in lengthy measurements and potentially making it impossible to complete the measurement within the specified timeframe. Currently, the Monte Carlo (MC) method is commonly used to measure frame error rates, which takes a long time and cannot meet the requirements of scenarios with high latency requirements.

[0004] Summary of the Invention

[0005] The present application provides a method and apparatus for measuring a frame error rate (FER), so as to reduce the measurement time of the FER.

[0006] In a first aspect, the present application provides a method for measuring a frame error rate, which can be applied to a first device, a functional module in the first device, a processor or chip in the first device, etc. Taking application to the first device as an example, the method may include: the first device obtaining an error frame and obtaining channel information and / or interference information corresponding to the error frame, and determining the frame error rate based on the channel information and / or interference information corresponding to the error frame.

[0007] Through the above method, the method of determining the frame error rate based on the channel information and / or interference information corresponding to the error frame can reduce the number of transmitted test frames. For example, the total number of frames only needs to be one percent of the total number of frames required by the current MC method, or even fewer frames. That is, the number of test frames used to obtain an accurate frame error rate only needs to be one percent of the total number of frames required by the current MC method, or even fewer frames. Therefore, the measurement time can be reduced and the measurement efficiency can be improved.

[0008] In one possible design, the first device obtains the channel information and / or interference information corresponding to the error frame, and the method may be: the first device determines the channel information and / or interference information corresponding to the error frame from the channel information and / or interference information corresponding to all frames generated by the first device; or, the first device receives the channel information and / or interference information corresponding to all frames from the second device, and determines the channel information and / or interference information corresponding to the error frame from the channel information and / or interference information corresponding to all frames; or, the first device sends the frame identifier of the error frame to the second device, and the frame identifier of the error frame is used to determine the channel information and / or interference information corresponding to the error frame; the first device receives the channel information and / or interference information corresponding to the error frame from the second device.

[0055] It should be noted that the device for measuring the frame error rate in Figure 1 can be a general term for devices that implement measuring the frame error rate. The device for measuring the frame error rate can be one device (for example, a device that combines the functions of a channel simulation device and a test device), or it can include two devices (for example, a test device and a channel simulation device), or it can include more than two devices, which is not limited in this application.

[0056] To facilitate understanding, some technical terms involved in the embodiments of this application are explained below:

[0057] Frame Error Rate:

[0058] The communication link between a typical transmitting device and a receiving device can be shown in Figure 2. Here, x is the transmitted signal sequence, h is the channel coefficient, z is Gaussian white noise, and y is the received signal sequence. These parameters conform to the formula y = hx + z. Let x = {xi} be a series of complex signal sequences obtained by encoding and modulating the original information frame (frame) or information block (block) m, and y = {yi} be the received signal sequence. The signal frame obtained by the receiving device after demodulating and decoding the received signal sequence y is denoted as m'. When m' = m, information frame m is considered to have been transmitted correctly. Conversely, when m' ≠ m, information frame m is considered to have been transmitted in error. The frame error rate (or block error rate) refers to the average probability of an information frame or information block being transmitted incorrectly during data transmission.

[0059] Taking the additive white Gaussian noise (AWGN) channel as an example, the frame error rate can be in accordance with the following formula 1:

[0060]

[0061] Where P(e) is the frame error rate, z∈cN n is n-dimensional complex Gaussian white noise, f(z) is the noise joint density function, and f(z) can meet the following formula 2:

[0062]

[0063] Where σ is the noise power, z i is the Gaussian white noise corresponding to the i-th frame.

[0064] I() represents the error indication function, and I() conforms to the following formula 3:

[0065]

[0066] That is, when the frame transmission is incorrect, the value of function I() is 1, and when the frame transmission is correct, the value of function I() is 0.

[0067] Some communication equipment needs to be tested in accordance with standardized indicators before leaving the factory to ensure that the equipment meets the design requirements set by industry standards. For example, in the performance test of communication equipment, receiver performance is an important technical indicator to measure the performance of the equipment, which is generally expressed by measuring the frame error rate. At present, the MC method is usually used to measure the frame error rate. The MC method is usually based on the law of large numbers, which can ensure that when the total number of frames is large enough (generally hundreds of times the inverse of the frame error rate), the ratio between the number of error frames and the total number of frames can approach the true value of the frame error rate. For the requirement of frame error rate = 10 -1 ~10 -2For devices with a high frame error rate, the MC method can complete the frame error rate measurement in a short time (such as 5 minutes). However, for devices with higher frame error rate requirements, such as those with a frame error rate of 10 -6 ~10 -8 For equipment with this type of equipment, the traditional MC method takes a long time, for example, the measurement time may take one month or even one year, which reduces the measurement efficiency.

[0068] Based on this, an embodiment of the present application provides a method for measuring frame error rate to reduce measurement time and improve measurement efficiency.

[0069] Based on the above description, the method for measuring the frame error rate provided in the embodiment of the present application is described in detail below. The method for measuring the frame error rate provided in the embodiment of the present application can be applied to the scenario shown in Figure 1. Referring to Figure 3, the detailed process of the method for measuring the frame error rate provided in the embodiment of the present application may include the following steps:

[0070] Step 301: The first device obtains an error frame.

[0071] Step 302: The first device obtains channel information and / or interference information corresponding to the error frame.

[0072] Step 303: The first device determines a frame error rate according to channel information and / or interference information corresponding to the error frame.

[0073] The above-mentioned method of determining the frame error rate based on the channel information and / or interference information corresponding to the error frame can reduce the number of transmitted test frames. For example, the total number of frames only needs to be one percent of the total number of frames required by the current MC method, or even fewer frames. That is, the number of test frames used to obtain an accurate frame error rate only needs to be one percent of the total number of frames required by the current MC method, or even fewer frames. Therefore, the measurement time can be reduced and the measurement efficiency can be improved.

[0074] Optionally, the first device may be a test device; or the first device may be a device with both test and channel simulation functions. Alternatively, the first device may be understood as a combination of a test device and a channel simulation device. It should be understood that the terms "test device" and "channel simulation device" are merely example device names and do not limit this application. This application is described solely as an example. The following describes different scenarios of the first device using Examples A and B.

[0075] Embodiment a: The first device is a device with testing and channel simulation functions, such as the first device in the scenario of measuring frame error rate shown in Figure 4. This embodiment a can be understood as the scenario shown in Figure 1, where the device for measuring frame error rate includes one device.

[0076] In this embodiment a, the first device can generate channel information and / or interference information corresponding to each frame, can provide test frames for the sending device, can obtain decoded frames from the receiving device, can determine the frame error rate and output the frame error rate.

[0077] Optionally, the first device may generate multiple channel information and / or multiple interference information. For example, the first device may determine channel parameters such as channel power and / or interference noise power, and then generate multiple channel information and / or multiple interference information based on the channel parameters.

[0078] Optionally, in the present application, the interference information may include interference signals and noise, etc. The interference signal may be an interference sequence, etc., as shown in FIG4 . The channel information may be a channel sequence, as shown in FIG4 .

[0079] In an optional embodiment, the first device obtains the channel information and / or interference information corresponding to the error frame. The method may be: the first device determines the channel information and / or interference information corresponding to the error frame from the channel information and / or interference information corresponding to all frames generated by the first device.

[0080] In one example, the first device obtains the error frame by: the first device determines multiple test frames, obtains multiple decoded frames, and determines the error frame based on the multiple test frames and the multiple decoded frames.

[0081] Specifically, the first device generates multiple test frames and sends the multiple test frames (for example, N test frame sequences {m1, m2, ..., m N}, where N is an integer greater than or equal to 2), the transmitting device inputs multiple test frames into the communication link between the transmitting device and the receiving device, which can also be understood as the transmitting device sending multiple test frames to the receiving device. The receiving device receives and decodes the test frames to obtain multiple decoded frames (for example, N corresponding decoded frames {m1', m2', ..., m N '}), and sends multiple decoded frames to the first device through the decoded frame interface of the first device. The first device compares the multiple test frames and the multiple decoded frames. When the i-th test frame is not equal to the i-th decoded frame, the i-th frame is determined to be an error frame, which can be recorded as when m i ≠m i ', the i-th frame is an error frame Ii=1, otherwise Ii=0. For details, please refer to the above formula 3. Based on this, the first device can determine the error frame according to multiple test frames and multiple decoded frames. Exemplarily, the number of error frames can be one or more.

[0082] The communication link for transmitting the test frame between the sending device and the receiving device can be specifically shown in FIG2 , and will not be described in detail here.

[0083] In an optional embodiment, the first device may determine the frame error rate based on the channel information and / or interference information corresponding to the error frame by the following method: the first device determines the weight of the error frame based on the channel information and / or interference information corresponding to the error frame; and then, the first device determines the frame error rate based on the weight of the error frame.

[0084] Exemplarily, the first device determines the weight of the error frame according to the interference information corresponding to the error frame, which may comply with the following formula 4:

[0085]

[0086] Among them, w i is the weight of the i-th frame, when the i-th frame is an error frame, w i is the weight of the error frame, z i is the interference information corresponding to the i-th frame, σ1 is the real noise power corresponding to the simulated signal-to-noise ratio, σ2 is the noise power used by the importance sampling method, and generally σ2 needs to satisfy σ2>σ1. The typical value of σ2 is an integer multiple of σ1, and n is the noise dimension.

[0087] Optionally, the frame error rate determined by the first device may comply with the following formula 5:

[0088]

[0089] Where FER is the frame error rate; N is the number of frames, N is a positive integer; I is the error indication function, when the i-th frame is an error frame, I i is 1, otherwise I i is 0; w i is the weight of the i-th frame, w i The determination is based on channel information and / or interference information corresponding to the i-th frame.

[0090] It should be noted that, since the i-th frame is a correct frame, that is, not an error frame, I in Formula 5 i It is 0, so it can be understood that the frame error rate is determined based on the weight of the error frame.

[0091] Illustratively, in this embodiment a, when the first device implements the above operation, it can be implemented through one module in the first device, or it can also be implemented through two modules in the first device.

[0092] In an optional embodiment, when implemented by two modules in the first device, the two modules may be shown as the channel simulation module and the test module in Figure 5. It should be understood that the two modules in Figure 5 are merely examples and do not limit the present application. The following description only uses the channel simulation module and the test module as examples.

[0093] Optionally, in the scenario shown in FIG5 , the test module can provide a test frame to the transmitting device, obtain a decoded frame from the receiving device, determine the frame error rate, and output the frame error rate. The test module can determine channel parameters such as channel power and / or interference noise power, and transmit the channel parameters to the channel simulation module. The channel simulation module can generate multiple channel information and / or multiple interference information based on the channel parameters. Alternatively, the test module can also generate multiple channel information and / or multiple interference information based on the channel parameters, and transmit the multiple channel information and / or multiple interference information to the channel simulation module.

[0094] Among them, the test module can obtain the channel information and / or interference information corresponding to the error frame. For example, the test module obtains the channel information and / or interference information corresponding to all frames from the channel simulation module, and determines the channel information and / or interference information corresponding to the error frame from the channel information and / or interference information corresponding to all frames. For another example, after the test module determines the error frame, it transmits the frame identifier of the error frame to the channel simulation module. The channel simulation module determines the channel information and / or interference information corresponding to the error frame based on the frame identifier of the error frame, and transmits the channel information and / or interference information corresponding to the error frame to the test module.

[0095] Optionally, when the channel simulation module transmits the channel information and / or interference information corresponding to the error frame to the test module, it can also transmit the frame identifier of the error frame to the test module so that the test module can identify the channel information and / or interference information corresponding to the error frame.

[0096] It should be understood that the interaction between the above-mentioned test module and the channel simulation module is an internal implementation of the first device.

[0097] Optionally, when the aforementioned operations of the first device are implemented by a single module, for example, the module may be a combined test module and channel simulation module, or another module that implements the functions of the first device. It should be understood that when the module is a combined test module and channel simulation module, the aforementioned interactive operations between the test device and the channel simulation module do not exist.

[0098] Through the above embodiment a, generation of channel information and / or interference information and measurement of frame error rate can be achieved through one device, which can improve the efficiency of measuring the frame error rate and reduce the deployment of measurement devices.

[0099] Embodiment B: The first device is a test device, such as the test device shown in Figure 6. This embodiment B can be understood as referring to the scenario shown in Figure 1, where the device for measuring the frame error rate includes two devices: a first device and a second device. The second device in this application is described using a channel simulation device as an example and is not intended to limit this application.

[0100] In this embodiment (b), the test device can provide test frames to the transmitting device, obtain decoded frames from the receiving device, determine the frame error rate (FR) and output the FR.

Alternatively, the test device may determine channel parameters such as channel power and / or interference noise power, and generate multiple channel information and / or interference information based on the channel parameters, and send the multiple channel information and / or interference information to the channel simulation device.

[0102] In this embodiment b, the method for the test device to obtain the error frame can refer to the method for the first device to obtain the error frame in the above embodiment a, and the method for the test device to determine the frame error rate based on the channel information and / or interference information corresponding to the error frame can refer to the method for determining the frame error rate based on the channel information and / or interference information corresponding to the error frame in the above embodiment a, which will not be described in detail here.

[0103] In an optional manner c1, the test device may obtain the channel information and / or interference information corresponding to the error frame in the following manner: the test device receives the channel information and / or interference information corresponding to all frames from the channel simulation device, and determines the channel information and / or interference information corresponding to the error frame from the channel information and / or interference information corresponding to all frames. Accordingly, the channel simulation device determines the channel information and / or interference information corresponding to all frames and sends the channel information and / or interference information corresponding to all frames to the test device.

[0104] Exemplarily, the test device may receive channel information corresponding to all frames from the channel simulation device through a first interface, and / or receive interference information corresponding to all frames from the channel simulation device through a second interface.

[0105] Optionally, the first interface and the second interface may be the same interface or two different interfaces.

[0106] In one example, when the test device receives channel information and / or interference information corresponding to all frames from the channel simulation device, the test device can also receive frame identifiers corresponding to all frames from the channel simulation device, and the frame identifier of each frame corresponds to the channel information and / or interference information of each frame, so that the test device can determine the correspondence between the error frame and the channel information and / or interference information of the error frame.

[0107] Based on the method c1, an example of a method for measuring a frame error rate may be shown in FIG7 , and the process may be:

[0108] Step 701: The testing device determines channel parameters, which may include channel power and / or interference noise power, etc.

[0109] Step 702: The test device sends channel parameters to the channel simulation device.

[0110] Step 703: The channel simulation device generates a plurality of channel information and / or interference information according to the channel parameters.

[0111] The plurality of channel information and / or interference information is used for a communication link between a transmitting device and a receiving device.

[0112] Step 704: The test device generates a plurality of test frames.

[0113] Step 705: The testing device sends multiple test frames to the sending device.

[0114] Step 706: The sending device transmits multiple test frames to the receiving device.

[0115] Step 707: The receiving device decodes the multiple test frames to obtain multiple decoded frames.

[0116] Step 708: The receiving device sends multiple decoded frames to the testing device.

[0117] Step 709: The test equipment determines an error frame according to the multiple test frames and the multiple decoded frames.

[0118] Step 710: The channel simulation device sends channel information and / or interference information of all frames to the test device.

[0119] Step 711: The test device determines the channel information and / or interference information corresponding to the error frame from the channel information and / or interference information corresponding to all frames.

[0120] Step 712: The test device determines a frame error rate according to the channel information and / or interference information corresponding to the error frame.

[0121] Specifically, the specific implementation method of each step in the above example can be found in the above related description, which will not be repeated here.

[0122] In an optional method c2, the test device can obtain the channel information and / or interference information corresponding to the error frame in the following manner: the test device sends a frame identifier of the error frame to the channel simulation device, and the frame identifier of the error frame is used to determine the channel information and / or interference information corresponding to the error frame; the test device receives the channel information and / or interference information corresponding to the error frame from the channel simulation device. Accordingly, the channel simulation device receives the frame identifier of the error frame from the test device, determines the channel information and / or interference information corresponding to the error frame based on the frame identifier of the error frame, and sends the channel information and / or interference information corresponding to the error frame to the test device.

[0123] Exemplarily, the test device can send the frame identifier of the error frame to the channel simulation device through the third interface; the test device can receive channel information corresponding to the error frame from the channel simulation device through the fourth interface, and / or receive interference information corresponding to the error frame from the channel simulation device through the fifth interface.

[0124] Optionally, the fourth interface and the fifth interface may be the same interface or two different interfaces.

[0125] Optionally, the third interface can be implemented through the same interface as the fourth interface and the fifth interface. For example, when the test device sends information to the channel simulation device, the interface can function as the third interface and can be understood as a downlink interface; when the test device receives information from the channel simulation device, the interface can function as the fourth interface and the fifth interface and can be understood as an uplink interface.

[0126] In one example, when the test device receives channel information and / or interference information corresponding to an error frame from a channel simulation device, the test device can also receive a frame identifier of the error frame from the channel simulation device, and the frame identifier of each error frame corresponds to the channel information and / or interference information of each error frame, so that the test device can determine the correspondence between the error frame and the channel information and / or interference information of the error frame.

[0127] Based on the method c2, an example of a method for measuring a frame error rate may be shown in FIG8 , and the process may be:

[0128] Steps 801 to 809 are similar to the above-mentioned steps 701 to 709 and can be referred to each other, so they will not be described in detail here.

[0129] Step 810: The test device sends a frame identifier of the error frame to the channel simulation device.

[0130] Step 811: The channel simulation device determines the channel information and / or interference information corresponding to the error frame according to the frame identifier of the error frame.

[0131] Step 812: The channel simulation device sends the channel information and / or interference information corresponding to the error frame to the test device.

[0132] Step 813: The test device determines a frame error rate according to the channel information and / or interference information corresponding to the error frame.

[0133] Specifically, the specific implementation method of each step in the above example can be found in the above related description, which will not be repeated here.
