[0002] In the performance test of wireless devices, OTA (Over-the-air) test is often used. OTA test is used to evaluate the overall RF performance of wireless devices. It is to calculate the transceiver performance index of wireless devices by testing the radiation performance of wireless devices at different angles.

[0048] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0049] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0050] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0051] First, the terms used in this application are explained.

[0052] TIS (Total Isotropic Sensitivity) is a receiving performance indicator in OTA testing. TIS is calculated by integrating EIS (Effective Isotropic Sensitivity). EIS is the power value at the front end of the receiving antenna that makes the receiver work at the sensitivity threshold. In general, the standard for judging the sensitivity of the receiver is based on the communication error rate BER (Bit Error Rate). For example, under the GSM (Global System for Mobile Communication) standard, when the communication bit error rate is 2.44%, the antenna front end power is considered to be the EIS value for that direction and polarization.

[0053] In the definition of relevant test standards, EIS is related to the receiver's own sensitivity and antenna gain, and its definition is as follows:

[0054]

[0055] Among them, EIS x (θ, φ) represents the equivalent omnidirectional sensitivity of x polarization at angle (θ, φ), P s is the radiated sensitivity of the receiver, G x,EUT (θ, φ) is the x-polarized antenna gain at (θ, φ). Radiated sensitivity P s It is an important parameter in OTA testing. When the total power is adjusted to make the receiver work stably at the threshold BER, the power received by the receiver front end is the receiver radiation sensitivity P. s size.

[0056] In the test standard, the TIS test requires testing the receiving sensitivity of each point in the three-dimensional space at intervals of 30° (pitch angle and horizontal azimuth angle), and calculating the average value on the spherical surface by integration. The calculation formula is as follows:

[0057]

[0058] Where N represents the number of sampling points of discrete sampling on the phi axis, M represents the number of sampling points of discrete sampling on the theta axis, EIS θ (θ i ,φ j ) means (θ i ,φ j )Equivalent omnidirectional sensitivity of θ polarization at angle θ, EIS θ (θ i ,φ j ) means (θ i ,φ j ) is the equivalent omnidirectional sensitivity of φ polarization at an angle of φ.

[0059] In the standard EIS test process given by CTIA (Cellular Telecommunications and Internet Association), such as Figure 1 As shown in the figure, the process of achieving this is to gradually reduce the output power of the instrument until the communication bit error rate is greater than or equal to the downlink power of the threshold bit error rate. It should be noted that although the standard stipulates the threshold bit error rate, such as 1.2% for TD-SCDMA and 2.44% for GSM, it is quite time-consuming to accurately obtain this number during the test. Therefore, the standard stipulates that the power that first breaks through the threshold bit error rate is the required power.

[0060] In the embodiment of the present invention, within the test range of the test antenna, the test position of each receiver of the wireless device to be tested is determined according to the antenna gain difference of each receiver of the wireless device to be tested, thereby implementing the test of each receiver of the wireless device to be tested.

[0061] Please refer to Figure 2 An embodiment of the present invention provides a method for testing a wireless device, including steps 101 to 103, wherein the wireless device involved in this embodiment has at least two receivers, which is described in detail below.

[0062] Step 101: Obtain the test range of the test antenna and the antenna gain corresponding to each receiver of the wireless device to be tested. In the test system that executes the test method, at least one test antenna is included. The signal radiated by the device to be tested can be received by the test antenna within a certain range. In this embodiment, the test range of the test antenna refers to the set of spatial ranges in which the test antenna can receive the signal radiated by the wireless device to be tested. The antenna gain of the receiver can be obtained through the antenna gain pattern of the receiving antenna of the receiver. In this embodiment, the antenna gain pattern of the receiver can be obtained through a variety of existing methods, for example: testing the antenna gain pattern of each receiver, or importing the antenna gain pattern obtained by pre-testing, or importing the antenna gain pattern obtained by pre-simulation or calculation.

[0063] The spatial position relationship between the test antenna and the wireless device to be tested during the test is described below.

[0064] In one example, the wireless device to be tested is fixedly arranged, and one or more test antennas can move (for example, the test antenna is installed on a moving mechanism such as a slide rail or an industrial robot arm). In this case, the test range is a set of spatial ranges within the moving range of the test antenna that can receive signals radiated by the wireless device to be tested; in another example, one or more test antennas are fixedly arranged, and the wireless device to be tested can move (for example, the wireless device to be tested is placed on a one-axis turntable or a two-axis turntable in the related art). In this case, the test range is a set of spatial ranges within which the test antenna can receive signals radiated by the wireless device to be tested when the test antenna is in different relative positions with the wireless device to be tested; in another example, the wireless device to be tested and one or more test antennas can both move. Similarly, the test range is a set of spatial ranges within which the test antenna can receive signals radiated by the wireless device to be tested when the test antenna is in different relative positions with the wireless device to be tested; in another example, the wireless device to be tested and multiple test antennas are fixedly arranged, and the test range is the fixed spatial positions where the multiple test antennas are located.

[0065] This embodiment uses the following two examples to illustrate two situations of the test range of the test antenna.

[0066] (1) Please refer to Figure 3 , Figure 3 An example of a test system for a wireless device to be tested is shown, including a turntable 200 and a test antenna 300. The turntable 200 is used to carry the wireless device to be tested 100. This embodiment is described by taking 9 test antennas as an example. The 9 test antennas 300 are fixedly arranged within a 180° arc range with the wireless device to be tested 100 as the center. The test range is the spatial positions corresponding to the 9 test antennas 300. Figure 3In the test system shown, the turntable 200 for placing the wireless device 100 under test rotates 180° in the horizontal plane with a sampling interval of 20° during the test. Therefore, its test range is the discrete spatial positions with theta angle and phi angle on the surface of the upper hemisphere with the device under test 100 as the sphere center and the test distance (i.e., the distance between the test antenna 300 and the device under test 100) as the radius, and the theta angle and the phi angle are both spaced 20° apart.

[0067] (2) Please refer to Figure 4 , Figure 4 Another example of a test system for a wireless device to be tested is shown. This embodiment is described by taking one test antenna as an example. One test antenna 300 is installed on an arc-shaped scanning frame and can move along the arc-shaped track of the scanning frame in a 180° arc range with the wireless device to be tested 100 as the center. The turntable 200 for placing the wireless device to be tested 100 can rotate 180° in the horizontal plane. The test range is theoretically a continuous surface of the upper hemisphere with the wireless device to be tested 100 as the center and the test distance as the radius.

[0068] Step 102: within the test range of the test antenna, determine the test position corresponding to each receiver according to the antenna gain corresponding to each receiver.

[0069] In one embodiment, in step 102, determining the test position of each receiver according to the antenna gain corresponding to each receiver includes: taking each receiver as a receiver to be tested one by one; and determining the test position of the receiver to be tested according to the magnitude relationship between the antenna gain of the receiver to be tested and the antenna gain of other receivers when the test antenna is at different positions, so as to obtain the test position of each receiver. The different positions of the test antenna are all within the test range of the test antenna.

[0070] Please refer to Figure 5 , according to the antenna gain corresponding to each receiver, determining the test position corresponding to each receiver includes steps 1021 to 1023.

[0071] Step 1021: Use each receiver as a receiver to be tested one by one.

[0072] Step 1022: Determine multiple positions to be evaluated of the test antenna within the test range of the test antenna. In one embodiment, when the test range is a discrete spatial position, each discrete spatial position is used as a plurality of positions to be evaluated, for example, Figure 3 In the embodiment shown, the device under test 100 is taken as the sphere center, and the theta angle and the phi angle on the upper hemisphere surface corresponding to the nine test antennas 300 are discrete spatial positions with intervals of 20° as positions to be evaluated. In another embodiment, when the test range is a continuous surface (e.g. Figure 4In the embodiment shown in the figure), discrete points can be taken on the continuous surface at preset intervals to determine the positions to be evaluated according to the test requirements. It can be understood that when the preset interval is small, the amount of calculation is correspondingly large, but it is easier to obtain a test position with higher test accuracy.

[0073] Step 1023: Obtain the difference between the antenna gain of the receiver under test and other receivers when the test antenna is at each position to be evaluated. Each position to be evaluated corresponds to the difference between the antenna gain of the receiver under test and other receivers.

[0074] Step 1024: Determine whether the difference in antenna gain corresponding to each position to be evaluated is greater than or equal to 0; if greater than or equal to 0, the corresponding position to be evaluated is used as the test position corresponding to the receiver to be tested; otherwise, the corresponding position to be evaluated is used as the unavailable position corresponding to the receiver to be tested. In this way, the test position of the receiver to be tested can be obtained, and then return to step 1021, and use other receivers as receivers to be tested in turn, and repeat steps 1021 to 1024 until the test positions of all receivers are obtained.

[0075] In some embodiments, the step of obtaining the test position is not limited to the order described above, for example, step 1022 may be performed first, and then step 1021, step 1023, and step 1024 may be performed in sequence. In some embodiments, in order to improve the accuracy of the test, step 1024 may also be: determining whether the difference in antenna gain corresponding to each position to be evaluated is greater than or equal to a preset value, where the preset value is any number greater than 0; if it is greater than or equal to the preset value, the corresponding position to be evaluated is used as the test position corresponding to the receiver to be tested, otherwise the corresponding position to be evaluated is used as an unavailable position corresponding to the receiver to be tested, so as to further improve the accuracy of the test.

[0076] As an example, this preset value may be limited to be greater than or equal to 3 dB. For this preset value, compared with the receiver to be tested, the contribution of other receivers to the received energy is very low, and it can be approximately considered that the other receivers are not working.

[0077] The method from step 1021 to step 1022 is described below with an example.

[0078] Assume that the wireless device to be tested has three receivers, and the test range of the test antenna includes four positions A, B, C, and D to be evaluated. For one of the receivers to be tested, the differences in antenna gain with the other two receivers calculated at the four positions to be evaluated are A(4, 5), B(3, 7), C(1, 6), and D(-1, 7) (in dB). Among them, at position D, the differences in antenna gain between the receiver to be tested and the other two receivers are -1 and 7, respectively, where -1 indicates that the antenna gain of the receiver to be tested at this position is smaller than that of the other receiver, so position D is determined to be an unusable position. Furthermore, in order to improve the test accuracy, for example, if the preset value is set to 2, position C is also determined to be unusable. Finally, the test positions of the receiver to be tested include position A and position B.

[0079] In some embodiments, there may be more than one test position obtained according to the method described in steps 1021 to 1023 above, so it is necessary to select an optimal test position from multiple test positions. The specific method is shown in steps 1024 to 1024.

[0080] Step 1024: Obtain the difference in antenna gain of the receiver to be tested corresponding to the test antenna at each test position, and obtain at least two antenna gain difference groups, each antenna gain difference group corresponds to a test position, and each antenna gain difference group includes the difference in antenna gain between the receiver to be tested and other receivers at the corresponding test position.

[0081] Step 1025: extract the minimum value in each antenna gain difference group to obtain a minimum antenna gain difference set.

[0082] Step 1026: The test position corresponding to the maximum value in the minimum antenna gain difference set is taken as the best test position, and other test positions except the best test position are removed.

[0083] Based on the above example, the available test positions for the receiver to be tested include positions A and B. In the antenna gain difference group (4, 5) corresponding to position A, the minimum value is 4, and in the antenna gain group (3, 7) corresponding to position B, the minimum value is 3. Thus, the minimum antenna gain difference set (4, 3) of the receiver to be tested is obtained. The two sets in the set are compared, and the maximum value is 4. Therefore, position A is determined as the best test position.

[0084] Step 103: After determining the test position of each receiver of the wireless device to be tested, adjust the test antenna to the test position corresponding to each receiver in turn, test each receiver, and obtain the test result of each receiver.

[0085] In this embodiment, adjusting the position of the test antenna is to adjust the relative position between the test antenna and the wireless device to be tested. The following are several specific examples: when the test antenna is fixed and the wireless device to be tested can move, the position of the wireless device to be tested is adjusted according to the test position so that the relative position of the wireless device to be tested and the test antenna meets the test position; when the wireless device to be tested is fixed and the test antenna can move, the position of the test antenna is adjusted according to the test position so that the test antenna is located at the test position; when the wireless device to be tested and the test antenna can move, the position of either of them is arbitrarily adjusted according to the test position so that the relative position of the wireless device to be tested and the test antenna meets the test position; when the wireless device to be tested and multiple test antennas are fixed, the test antenna located at the test position is selected according to the test position for performing subsequent tests. In one embodiment, the EIS test is performed on each receiver. Taking the receiver to be tested as an example, the specific test method includes steps 1031 to 1032.

[0086] Step 1031: Calculate the radiation sensitivity corresponding to the test position. From the definition of EIS, we know that:

[0087]

[0088] Among them, P s is the radiation sensitivity, G x,EUT (θ, φ) is the antenna gain and x represents the polarization direction.

[0089] Based on the EIS obtained from the test at the test location and the antenna gain pattern corresponding to the test location, the radiation sensitivity can be calculated as: P s =G x,EUT (θ,φ)EIS x (θ,φ).

[0090] Step 1032: Calculate the equivalent omnidirectional sensitivity EIS corresponding to each point of the receiver under test in the preset spatial position. In some embodiments, according to some test specifications, the preset spatial position is a number of evenly distributed points on a sphere with the receiver under test as the center and a certain distance as the radius. Specifically, the theta axis includes 5 points, and the angles of each point are 30°, 60°, 90°, 120°, and 150° respectively; the phi axis includes 12 points, and the angle interval of each point is 30°. The angle interval is not limited to this. It can be understood that the preset spatial position in this embodiment includes polarization. Since the antenna gain pattern of the receiver under test is known, the antenna gain of each point in the preset spatial position can be obtained by the following formula: The equivalent omnidirectional sensitivity EIS corresponding to each point can be calculated.

[0091] In another embodiment, the TIS test is performed on each receiver. The specific test method is to further perform the following step 1033 on the basis of the above steps 1031 to 1032:

[0092] Step 1033: According to the calculation result of S1032, the TIS of the receiver under test is obtained according to the integral calculation of the relevant technology center.

[0093] This embodiment can also obtain the overall performance of the wireless device to be tested based on the wireless performance test results of each receiver. Figure 6 , based on the above steps 101 to 103, it also includes step 104, which is described in detail below.

[0094] Step 104: Determine the test result of the wireless device under test according to the test results of each receiver. In one embodiment, step 104 specifically performs: determining the total omnidirectional sensitivity of the wireless device under test according to the total omnidirectional sensitivity of each receiver of the wireless device under test.

[0095] In one embodiment, in step 104 , determining the total omnidirectional sensitivity of the wireless device to be tested includes steps 1041 to 1042 .

[0096] Step 1041: Calculate the EIS corresponding to each point of the wireless device under test in the preset spatial position. The definition of the preset spatial position has been explained in step 1032 and will not be repeated here. The specific calculation method is: at each point of the preset spatial position, compare the EIS values ​​of each receiver, select the minimum value therein, and determine it as the EIS value of the wireless device under test at the point corresponding to the minimum value.

[0097] Step 1042: Obtain the TIS value of the wireless device under test by integral calculation according to the EIS value of the wireless device under test at the point corresponding to the minimum value obtained in step 1041. In this embodiment, the method for obtaining the TIS value of the wireless device under test by integral calculation can adopt any existing method, which will not be described in detail here.

[0098] In the OTA test related technologies, for some large wireless devices, such as vehicle equipment, due to the small test distance, the TIS test angle interval is usually much smaller than the 30° specified in the standard. In the related technologies, the actual sampling angle interval can reach 2°, or even denser than 2°, which will lead to extremely long test time and slow test speed. The test method of the embodiment of the present invention can quickly obtain the TIS test results of each receiver of the wireless device and the TIS results of the entire wireless device, greatly improving the test efficiency.

[0099] The present invention also provides a wireless device testing device. Figure 7 The testing device of the wireless device includes: a wireless gain acquisition module 201, a test position determination module 202 and a testing module 203.

[0100] The antenna gain acquisition module 201 is used to acquire the test range of the test antenna of the wireless device under test and the antenna gain corresponding to each receiver of the wireless device under test.

[0101] The test position determination module 202 is used to determine the test position corresponding to each receiver within the test range of the test antenna according to the antenna gain corresponding to each receiver.

[0102] The testing module 203 is used to adjust the testing antenna to the testing position corresponding to each receiver in turn, test each receiver, and obtain the testing result of each receiver.

[0103] The above modules are functional modules corresponding to the method steps provided in the above embodiments, and their specific implementation methods have been described in detail in the above embodiments, which will not be repeated here.
