Abstract

A method and apparatus for measuring a frame error rate that reduces the duration of measuring the frame error rate. A first device acquires an error frame, acquires channel information and / or interference information corresponding to the error frame, and determines a frame error rate based on the channel information and / or interference information corresponding to the error frame. The method for determining a frame error rate based on the channel information and / or interference information corresponding to the error frame can reduce the number of test frames transmitted. For example, the total number of frames needs to be no more than 1% of the total number of frames required for the current MC method. In other words, the number of test frames used to obtain an accurate frame error rate needs to be no more than 1% of the total number of frames required for the current MC method. Therefore, the measurement duration can be reduced and measurement efficiency can be improved.

Description

[Technical Field]

[0001] The present application relates to the field of communications technology, and more particularly to a method and apparatus for measuring frame error rates. [Background technology]

[0002] In performance testing of communication devices, receiver performance is an important technical indicator for measuring device performance, and is generally expressed by measuring the frame error rate (FER), which refers to the average probability that an information frame is transmitted incorrectly during data transmission.

[0003] For conventional 2G / 3G / 4G mobile broadband (MBB) services, the frame error rate is generally FER=10 -1 ~10 -2 The frame error rate measurement of this order can be completed in a short time. However, with the emergence of scenarios with high latency requirements, such as the emergence of 5G ultra reliable and low latency communication (URLLC) scenarios, the frame error rate indicator has higher requirements (e.g., FER=10 -6 ~10 -8 ) is imposed. This poses a greater challenge to measuring the frame error rate of a device, which not only results in a long measurement time but may even make it impossible to complete the measurement in a limited time. In addition, the currently used method for measuring the frame error rate is usually the Monte Carlo (MC) method, which has a long measurement time, and cannot meet the requirements of scenarios with high latency requirements. Summary of the Invention [Means for solving the problem]

[0004] The present application provides a method and apparatus for measuring a frame error rate, in order to reduce the duration of measuring the frame error rate.

[0005] According to a first aspect, the present application provides a method for measuring a frame error rate. The method may be applied to a first device, a functional module within the first device, a processor or chip within the first device, or the like. As an example, a method applied to the first device is used. The method may include the first device acquiring an error frame, acquiring channel information and / or interference information corresponding to the error frame, and determining a frame error rate based on the channel information and / or interference information corresponding to the error frame.

[0006] According to the above method, the method for determining a frame error rate based on channel information and / or interference information corresponding to an error frame can reduce the number of test frames transmitted. For example, the total number of frames can be no more than 1% of the total number of frames required for the current MC method. In other words, the number of test frames used to obtain an accurate frame error rate can be no more than 1% of the total number of frames required for the current MC method. Therefore, the measurement duration can be reduced and measurement efficiency can be improved.

[0043] It should be noted that the device for measuring a frame error rate in Fig. 1 may be a generic term for devices for measuring a frame error rate. The device for measuring a frame error rate may be one device (e.g., a device that integrates the functions of a channel simulation device and a test device), may include two devices (e.g., a test device and a channel simulation device), or may include more than two devices. This is not limited in the present application.

[0044] For ease of understanding, the following will first explain some technical terms in the embodiments of this application.

[0045] Frame Error Rate: A typical communication link between a transmitting device and a receiving device can be shown in Figure 2. x is the transmitted signal sequence, h is the channel coefficient, z is white Gaussian noise, and y is the received signal sequence. The above parameters satisfy the equation y = hx + z. It is assumed that x = {xi} is a series of complex signal sequences obtained by encoding and modulating the original information frame or information block m, and y = {yi} is the received signal sequence. The signal frame obtained by the receiving device by 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 erroneously. The frame error rate (also called block error rate) refers to the average probability of a transmission error of an information frame or information block during data transmission.

[0046] Using an additive white gaussian noise (AWGN) channel as an example, the frame error rate may satisfy Equation 1 below:

number

[0047] P(e) is the frame error rate, z∈cN n is n-dimensional complex white Gaussian noise, f(z) is the noise joint density function, and f(z) may satisfy Equation 2 below:

number

[0048] σ is the noise power, and z i is the white Gaussian noise corresponding to the i-th frame.

[0049] I() represents the error indicator function, and I() satisfies the following equation 3.

number

[0050] In other words, when a frame is transmitted erroneously, the value of the function I() is 1, or when a frame is transmitted correctly, the value of the function I() is 0.

[0051] Currently, before shipping, some communication devices need to be tested to see if they meet standard indicators to ensure that the devices meet the design requirements specified in industry standards. For example, in performance testing of communication devices, receiver performance is an important technical indicator for measuring the performance of the device, and is generally expressed by measuring the frame error rate. Currently, 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 sufficiently large (generally several hundred times the inverse of the frame error rate), the ratio of the number of error frames to the total number of frames can approximate the actual value of the frame error rate. When the frame error rate is 10 -1 ~10 -2 For devices that require a frame error rate of about 10, the MC method can be used to complete the frame error rate measurement in a short time (e.g., 5 minutes). However, for devices with high frame error rate requirements, e.g., frame error rate = 10,-6 ~10 -8 For devices requiring high-speed measurement, the conventional MC method requires a long time. For example, the measurement time can be as long as one month or even one year. This reduces the measurement efficiency.

[0052] In view of this, the embodiments of the present application provide a method for measuring frame error rate to reduce the measurement duration and improve the measurement efficiency.

[0053] Based on the foregoing description, the following will describe in detail the method for measuring a frame error rate provided in an embodiment of the present application. The method for measuring a frame error rate provided in an embodiment of the present application can be applied to the scenario shown in Figure 1. Please refer to Figure 3. The detailed procedure of the method for measuring a frame error rate provided in an embodiment of the present application may include the following steps:

[0054] Step 301: A first device receives an error frame.

[0055] Step 302: The first device obtains channel information and / or interference information corresponding to the error frame.

[0056] Step 303: The first device determines a frame error rate based on the channel information and / or interference information corresponding to the error frame.

[0057] The above-described method for determining a frame error rate based on channel information and / or interference information corresponding to an error frame can reduce the number of test frames transmitted. For example, the total number of frames may be no more than 1% of the total number of frames required for the current MC method. In other words, the number of test frames used to obtain an accurate frame error rate may be no more than 1% of the total number of frames required for the current MC method. Therefore, the measurement duration can be reduced, and measurement efficiency can be improved.

[0058] Optionally, the first device may be a test device. Alternatively, the first device may be a device having a test function and a channel simulation function. This may be understood as the first device being a device that integrates a test device and a channel simulation device. It should be understood that the test device and the channel simulation device are merely examples of device names and are not intended to limit the present application. The present application is merely described using examples. The following will use embodiment a and embodiment b to separately describe different cases of the first device.

[0059] Embodiment a: The first device is a device having a test function and a channel simulation function, for example, the first device in the scenario of measuring a frame error rate shown in Fig. 4. Embodiment a can be understood as the device for measuring a frame error rate in the scenario shown in Fig. 1 including one device.

[0060] In embodiment a, the first device may generate channel information and / or interference information corresponding to each frame, may provide test frames to the transmitting device, may obtain decoded frames from the receiving device, may determine a frame error rate, and may output the frame error rate.

[0061] Optionally, the first device may generate a plurality of pieces of channel information and / or a plurality of pieces of interference information. For example, the first device may determine channel parameters such as channel power and / or interference-plus-noise power, and then generate a plurality of pieces of channel information and / or a plurality of pieces of interference information based on the channel parameters.

[0062] Optionally, the interference information in the present application may include an interference signal and noise, etc. The interference signal may be an interference sequence, etc., as shown in Figure 4. The channel information may be a channel sequence, as shown in Figure 4.

[0063] In an optional embodiment, the first device obtaining channel information and / or interference information corresponding to the error frame may be the first device determining channel information and / or interference information corresponding to the error frame from channel information and / or interference information corresponding to all frames generated by the first device.

[0064] In one example, the first device obtaining the error frame may be the first device determining a plurality of test frames, obtaining a plurality of decoded frames, and determining the error frame based on the plurality of test frames and the plurality of decoded frames.

[0065] Specifically, the first device generates a plurality of test frames and transmits the plurality of test frames (e.g., a sequence of N test frames {m1, m2, ..., m N}, where N is an integer equal to or greater than 1, to a transmitting device. The transmitting device inputs a plurality of test frames into a communication link between the transmitting device and the receiving device. This can also be understood as the transmitting device transmitting a plurality of test frames to the receiving device. The receiving device receives a plurality of decoded frames (e.g., N corresponding decoded frames {m1', m2', ..., m N Receive and decode test frames to obtain a plurality of decoded frames (i.e., a plurality of test frames '}), and send the plurality of decoded frames to the first device through the decoded frame interface of the first device. The first device compares the plurality of test frames with the plurality of decoded frames. When the ith test frame does not match the ith decoded frame, the ith frame is determined to be an error frame. This means that m i ≠m i', the i-th frame may be expressed as an error frame Ii=1, or Ii=0 otherwise. For details, see Equation 3 above. Based on this, the first device may determine an error frame based on multiple test frames and multiple decoded frames. For example, there may be one or more error frames.

[0066] For details regarding the communication links through which the transmitting device and the receiving device perform the transmission of the test frames, please refer to FIG. 2, and the details will not be described again here.

[0067] 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, which may be the first device determines a weight of the error frame based on the channel information and / or interference information corresponding to the error frame, and further the first device determines the frame error rate based on the weight of the error frame.

[0068] For example, the weight of the error frame determined by the first device based on the interference information corresponding to the error frame may satisfy Equation 4 below.

number

[0069] w i is the weight of the ith frame, and w i is the weight of the error frame when the i-th frame is an error frame, and z i is the interference information corresponding to the i-th frame, σ1 is the actual noise power corresponding to the simulated signal-to-noise ratio, σ2 is the noise power used in the importance sampling method, and σ2 generally needs to satisfy σ2 > σ1. A typical value of σ2 is an integer multiple of σ1, and n is the number of noise dimensions.

[0070] Optionally, the frame error rate determined by the first device may satisfy Equation 5 below:

number

[0071] FER is the frame error rate, N is the number of frames, N is a positive integer, I is the error indicator function, and when the ith frame is an error frame, I i is 1, or if the i-th frame is not an error frame, I i is 0 and w i is the weight of the ith frame, and w i is determined based on channel information and / or interference information corresponding to the i-th frame.

[0072] When the i-th frame is a correct frame, that is, when the i-th frame is not an error frame, I i Note that is 0. Therefore, it can be seen that the frame error rate is determined based on the weight of the error frame.

[0073] For example, in embodiment a, the first device may perform the aforementioned operations using one module within the first device, or may perform the aforementioned operations using two modules within the first device.

[0074] In an optional embodiment, when two modules in the first device are used for implementation, the two modules may be shown as a channel simulation module and a test module in Figure 5. It should be understood that the two modules in Figure 5 are merely an example and are not intended to limit the present application. The following uses only the channel simulation module and the test module as examples for explanation.
