Description

Technical Field

[0001] This invention relates to the field of communication equipment performance testing technology, and more particularly to a method and apparatus for testing the transmit antenna switching performance of a wireless terminal. Background Technology

[0002] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] Transmit antenna switching, or intelligent antenna switching, is called TAS (Transmit Antenna Selection) or ASDiV (Antenna Switch to Diversity). It refers to the automatic switching of the transmit antenna between the main antenna and the diversity antenna. During use, the antenna performance of smartphones is easily affected by how they are held and placed. When the performance of one antenna degrades due to being held or blocked, the phone signal can automatically switch to another antenna for transmission. This function effectively solves the signal congestion problems caused by holding or blocking the antenna, enabling faster data connections and transmission speeds, thus providing users with a more reliable mobile connection experience. With the rapid development of wireless communication technology and the rapid improvement of communication capabilities, transmit antenna switching technology has become an essential technology for wireless communication terminals such as smartphones and laptops.

[0004] To ensure the reliability and availability of transmit antenna switching performance in wireless communication terminals, a rigorous testing procedure is essential. Currently, industry testing of the transmit performance of multi-antenna wireless communication terminals primarily involves separate testing of the main antenna and diversity antenna transmit performance: with transmit antenna switching disabled, both the main antenna and diversity antenna are locked as the sole transmit antenna, and the TRP (Transmit Relay Performance) is tested for each locked transmit antenna. In other words, there is currently no effective solution in the industry to accurately evaluate the transmit antenna switching performance of wireless communication terminals. The main reason is:

[0005] 1. Transmit antenna switching algorithms are proprietary algorithms of each terminal equipment manufacturer. The conditions and mechanisms for triggering transmit antenna switching vary among manufacturers, including specific input triggers from external control sources such as base station control, user control, and received signal levels, as well as internal triggers from their own sensors (based on proximity to the human body and other objects). In current OTA testing systems, it is difficult to simulate different transmit antenna switching trigger conditions.

[0006] 2. Enable the transmit antenna switching function and test according to the existing wireless terminal transmit performance test method. If the transmit antenna switching is triggered at a certain spatial test point, it may cause the two polarization components measured at that point to come from different transmit antennas, thus leading to incorrect measurement results.

[0007] 3. The test results of the transmitting antenna switching performance are closely related to the anechoic chamber layout, including the turntable and fixtures, as well as the relative position of the communication antenna and the terminal under test. Therefore, the same device under test may produce drastically different transmitting antenna switching performance test results when tested in different anechoic chambers.

[0008] 4. The triggering of the transmitting antenna switching condition has a certain degree of randomness. Therefore, even if the same terminal under test is repeatedly tested in the same test system, the test results will differ due to this randomness.

[0009] In summary, there is an urgent need for a technical solution that can overcome the above-mentioned shortcomings and achieve accurate and efficient testing of the switching performance of wireless terminal transmitting antennas. Summary of the Invention

It should be understood that these embodiments are given merely to enable those skilled in the art to better understand and implement the invention, and are not intended to limit the scope of the invention in any way. Rather, these embodiments are provided to make this disclosure more thorough and complete, and to fully convey the scope of this disclosure to those skilled in the art.

Therefore, this disclosure can be specifically implemented in the following forms: entirely hardware, entirely software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

[0035] According to an embodiment of the present invention, a method and apparatus for testing the transmit antenna switching performance of a wireless terminal are proposed, relating to the field of communication equipment performance testing technology.

[0036] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0037] Figure 1 This is a schematic flowchart of a method for testing the transmit antenna switching performance of a wireless terminal according to an embodiment of the present invention. Figure 1 As shown, the method includes:

[0038] S101, disable the transmit antenna switching function;

[0039] S102, Measure the EIRP pattern of the main antenna respectively. and the EIRP pattern of diversity antennas

[0040] S103, randomly swap the measured EIRP pattern of the main antenna according to the preset swap probability. EIRP pattern of diversity antenna The EIRP values ​​in the data are used to obtain the combined EIRP pattern. Further calculation of the combined EIRP pattern TRP value comb ;

[0041] Repeat the previous step (S103) to obtain a certain number of TRPs. comb Sample, calculate TRP comb The statistical distribution parameters of the sample;

[0042] S104, determine the TRP according to the preset discrimination index. comb The test results of the transmit antenna switching performance are obtained by determining whether the statistical distribution parameter values ​​of the sample meet the discrimination criteria.

[0043] To provide a clearer explanation of the above-mentioned test method for the transmission antenna switching performance of wireless terminals, each step will be explained in detail below.

[0044] In S101, disable the transmit antenna switching function.

[0045] In S102, the EIRP pattern of the main antenna is measured. and the EIRP pattern of diversity antennas

[0046] In S103, the measured EIRP pattern of the main antenna is randomly swapped according to the preset swapping probability. EIRP pattern of diversity antenna The EIRP values ​​in the data are used to obtain the combined EIRP pattern. Further calculation of the combined EIRP pattern TRP value comb .

[0047] Repeat the previous step (S103) to obtain a certain number of TRPs. comb Sample, calculate TRP comb The statistical distribution parameters of the sample.

[0048] The specific process is as follows:

[0049] According to the preset exchange probability P n Random selection The proportion of P is n The EIRP value, replacing The EIRP values ​​at the corresponding locations are used to generate a combined EIRP pattern. The combined EIRP pattern was further calculated. TRP value comb .

[0050] The expression that replaces the EIRP value is:

[0051]

[0052] in, To combine the EIRP radiation patterns; The radiation pattern of the main antenna EIRP; The radiation pattern of the diversity antenna EIRP; P n Let be the probability of commutation.

[0053] @ indicates from The proportions of EIRP values ​​are randomly selected from the radiation pattern, and these proportions are swapped to obtain a combined radiation pattern. The sum of the proportions is 1.

[0054] The EIRP pattern is a matrix. For example, an EIRP pattern obtained by measuring at 30° angular intervals is a 7×12 matrix, where i and j are the indices of the corresponding positions.

[0055] By repeating the above process, a certain number of TRPs can be obtained. comb Sample, calculate TRP comb The statistical distribution parameters of the sample; for example, the number of repetitions could be 10,000 or 50,000, etc.

[0056] In one embodiment, the preset exchange probability is a step-size distribution value within the interval [0, 1]. The step size can be 0.1, 0.2, 0.05, etc.

[0057] Further reference Figure 2 This is a schematic diagram of a method flow according to a specific embodiment of the present invention. Figure 2 As shown, the method also includes:

[0058] S201, for each exchange probability P n Calculate the exchange probability P respectively. n Corresponding TRP comb The statistical distribution parameters of the sample.

[0059] This step (S201) is not necessary in practical applications. For example, in the first discrimination index mentioned in the later embodiments, if only one exchange probability (such as P) is selected... n =0.5), then only P needs to be calculated. n =0.5 is the exchange probability data; there is no need to execute S201 to calculate the probability of each exchange.

[0060] In one embodiment, the TRP comb The statistical distribution parameter of the sample is a combination of one or more of the following data:

[0061] TRP comb Sample standard deviation, TRP comb Sample mean, TRP comb The maximum value of the sample.

[0062] In practical applications, other TRPs can be calculated as needed. comb The statistical distribution parameters of the sample are used as data for S104 in making judgments.

[0063] In S104, the TRP is determined according to a preset discrimination index. comb The test results of the transmit antenna switching performance are obtained by determining whether the statistical distribution parameter values ​​of the sample meet the discrimination criteria.

[0064] Specifically, the discrimination indicators can be set according to the actual situation.

[0065] 1. The first type of discrimination criterion is:

[0066] Select one or more swap probabilities;

[0067] If the TRP corresponding to this exchange probability comb If the statistical distribution parameter value of the sample is greater than or equal to the set TRP limit, the transmit antenna switching performance is deemed qualified; otherwise, it is deemed unqualified.

[0068] For example, select P n =0.5, then during the execution of S103, the measured EIRP pattern of the main antenna is obtained. 50% of the EIRP values ​​were randomly selected and compared with the EIRP pattern of the diversity antenna. The EIRP values ​​at corresponding positions are swapped to obtain the combined EIRP pattern. Further calculation of the combined EIRP pattern TRP value comb .

[0069] Repeat the above process 10,000 or 50,000 times. Correspondingly, this will yield 10,000 or 50,000 TRPs. comb Sample, further calculate TRP comb The statistical distribution parameters of the sample.

[0070] Determine whether the value of the statistical distribution parameter is greater than or equal to the set TRP limit. If it is, the result is acceptable; otherwise, the result is unacceptable.

[0071] In one specific embodiment, reference is made to Figure 3 This is a different P from a specific embodiment of the present invention. n TRP comb A schematic diagram of the maximum value curve of the sample. (For example...) Figure 3 As shown, antenna 1 was randomly swapped multiple times with antennas 2, 3, 4, 5, and 6 according to different swap probabilities to obtain the EIRP value, and the TRP was calculated. comb Maximum value of the sample.

[0072] Taking the first type of discriminant as an example, the discriminant is: the exchange probability P. n =0.5 corresponding to TRP comb The maximum value of the sample is greater than or equal to -4dBm.

[0073] Then through Figure 3 It can be seen that antennas 1 and 5, and antennas 1 and 6 meet the discrimination criteria and are judged as qualified, while the others are unqualified.

[0074] 2. The second type of discrimination criterion is:

[0075] Set TRP limits;

[0076] Set TRP comb The probability limit P' of the statistical distribution parameter value of the sample is not lower than the TRP limit;

[0077] When TRP comb The statistical distribution parameter values ​​of the sample fall within a certain exchange probability interval [P] a P b When the value within the range is greater than or equal to the set TRP limit, calculate the probability value ΔP, where ΔP = P. b -P a ;

[0078] If the probability value ΔP is greater than or equal to the probability limit P', the transmitting antenna switching performance is deemed qualified; otherwise, it is deemed unqualified.

[0079] For example, set the TRP limit to -5dBm;

[0080] Set TRP comb The probability limit P' for the statistical distribution parameter value of the sample not being lower than -5dBm is 0.6;

[0081] Taking a step size of 0.1 as an example, P n =0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, respectively execute S103 to exchange the measured EIRP pattern of the main antenna according to the corresponding exchange probability. EIRP pattern of diversity antenna The EIRP values ​​at the corresponding positions are used to obtain the combined EIRP pattern. Further calculation of the combined EIRP pattern TRP value comb .

[0082] By repeating the above process, we can obtain the values ​​of each P through calculation. n Corresponding TRP comb sample.

[0083] Scenario 1:

[0084] When TRP comb When the statistical distribution parameter value of the sample is greater than or equal to -5dBm within the exchange probability interval [0.1, 0.8], the calculated probability value ΔP is 0.7.

[0085] Since the probability value ΔP(0.7) is greater than or equal to the probability limit P'(0.6), the switching performance of the transmitting antenna is deemed to be qualified.

[0086] Scenario 2:

[0087] When TRP comb When the statistical distribution parameter value of the sample is greater than or equal to -5dBm within the exchange probability interval [0.3, 0.7], the calculated probability value ΔP is 0.4.

[0088] Since the probability value ΔP(0.4) is less than the probability limit P'(0.6), it is judged as unqualified.

[0089] In the scenario of the second discrimination metric, it is necessary to consider each exchange probability P. n Calculate the exchange probability P respectively. n Corresponding TRP combIf the statistical distribution parameter values ​​of the sample exist within a probability interval that meets the discrimination criteria, then the sample is deemed qualified.

[0090] It should be noted that although the operation of the method of the present invention has been described in a specific order in the above embodiments and figures, this does not require or imply that the operations must be performed in that specific order, or that all the operations shown must be performed to achieve the desired result.
