Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on some embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, and may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0020] In communication systems, power is a key parameter. High-frequency time average power refers to the average value of signal power over a period of time within the high-frequency frequency band. In wireless communications, the signal strength transmitted by the base station is crucial to the coverage range and reception quality. By detecting the high-frequency time average power of the base station downlink signal, it can be determined whether the base station can effectively transmit to the target area. If the average power fluctuates too much, it may cause problems such as signal fading and increased bit error rate. For example, in digital communication systems, unstable power may cause incorrect signal judgment at the receiving end. There is a need to measure high-frequency time average power in many scenarios.

[0021] Research and practice have found that in high-frequency scenarios, the high-frequency time average power of the uplink signal of the communication terminal also has a great impact on the communication quality of the communication system, and some regions may also have special standard requirements for the high-frequency time average power of the uplink signal of the communication terminal. For example, in the manufacturing process of communication terminals, the high-frequency time average power measurement system can be used to test the RF performance of the product. For example, on the production line of smartphones, the wireless communication module of the smartphone can be tested for power. By measuring the uplink signal transmission power of the smartphone in different communication modes (such as LTE or 5G millimeter wave), it is helpful to ensure that the mobile phone transmission power meets the requirements of relevant standards and communication protocols. By sampling and testing mass-produced smartphones and statistically analyzing parameters such as the average value of the uplink signal transmission power, it is helpful to better control product quality and promptly discover problems in the production process, such as abnormal RF chip performance or poor antenna matching. Other scenarios where high-frequency time average power measurement is required will not be repeated here.

[0029] In some possible implementations, When the average time power of the millimeter wave uplink signal and / or the average time power of the LTE uplink signal corresponding to the first tested high-frequency communication terminal recorded in the first performance test report does not meet the preset power standard; the first terminal replacement instruction carries a test failure mark; the mechanical arm is also used to collect the first tested high-frequency communication terminal disconnected from the high-frequency communication terminal performance detection system into the unqualified terminal storage container; When the average time power of the millimeter wave uplink signal and the average time power of the LTE uplink signal corresponding to the first tested high-frequency communication terminal recorded in the first performance test report both meet the preset power standards; the first terminal replacement instruction carries a test pass mark; the robotic arm is also used to collect the first tested high-frequency communication terminal disconnected from the high-frequency communication terminal performance detection system into a qualified terminal storage container.

[0030] In some possible implementations, the real-time power measurement result of the 5G millimeter wave uplink signal corresponding to the first high-frequency communication terminal under test measured by the second power meter may include: the time domain waveform signal s(t) of the 5G millimeter wave uplink signal corresponding to the first high-frequency communication terminal under test.

[0031] The upper host control machine analyzes the real-time power measurement result of the received 5G millimeter wave uplink signal to obtain the average time power of the millimeter wave uplink signal corresponding to the first high-frequency communication terminal under test, which may include: The instantaneous power P(t) is calculated based on the time domain waveform signal s(t), where: : Where R represents the load impedance; Based on the instantaneous power P(t), the time average power P is calculated avg ,in, ; T represents the measurement time window.

[0032] The upper host control machine can set the measurement time window size according to specific needs, and notify the second power measuring device of the determined measurement time window through a test command; For example: Measurement time window ; Where B represents the bandwidth of the signal (Hz). symbol represents the symbol period, ΔP represents the measurement accuracy (for example, 0.02≥ΔP≥0.005), k represents the measurement noise constant, N represents the number of symbol periods to be captured (for example, 500≥N≥100), D represents the data packet size (bits) of the first measured high-frequency communication terminal, R represents the transmission rate (bps) of the first measured high-frequency communication terminal, M represents the cache size (bits) of the first measured high-frequency communication terminal, and C represents the processing rate (bps) of the first measured high-frequency communication terminal.

S represents the quiet zone size of the compact field (e.g., in meters).

[0034] It can be understood that the measurement time window determination method in other scenarios can refer to the above examples, but is not limited to the above examples.

[0035] In some possible implementations, the characteristic parameters of the test compact range are dynamically adjustable, and the upper host control machine can dynamically adjust the characteristic parameters of the test compact range according to the characteristics of the high-frequency communication terminal under test so that the two can have better matching.

[0036] For example, the upper host control machine can be communicatively connected with the main control chip built into the test compact field, and the upper host control machine can send characteristic parameter configuration instructions to the main control chip built into the test compact field, and adjust one or more characteristic parameters of the test compact field through the characteristic parameter configuration instructions.

[0037] For example, the upper host control machine can determine the quiet zone size S of the test compression field by the following formula: in, ; Wherein, S represents the size of the compact field quiet zone; k represents an empirical constant related to the test environment and accuracy requirements, and the value range of k can be, for example, between 10-20. t Indicates the transmission power of the high-frequency communication terminal under test. t represents the antenna gain of the high-frequency communication terminal under test (dimensionless). λ represents the operating wavelength of the high-frequency communication terminal under test. B represents the signal bandwidth of the high-frequency communication terminal under test (Hz). L represents the allowable power density loss factor (dimensionless), which is used to measure the acceptable variation range of power density in the quiet zone. The value range of L can be, for example, between 1.2 and 1.5.

[0038] For example, the upper host control machine can determine the quiet zone size S of the test compact field by the following formula: in, ; k represents the correction coefficient; n represents the number of working frequency bands of the high-frequency communication terminal under test. t1 and t2 are the start and end times of the measurement time window, respectively. Pt,i(t) represents the transmission power of the high-frequency communication terminal under test in the i-th working frequency band as a function of time t. i (θ, φ) represents the antenna gain pattern of the high-frequency communication terminal under test in the i-th working frequency band. The antenna gain pattern describes the radiation capability of the antenna in different directions and reflects the distribution of the signal in space. i Indicates the working wavelength of the i-th working frequency band. i Represents the signal bandwidth of the i-th operating frequency band. Li(t) represents the power density loss factor allowed for the i-th operating frequency band at time t. Li(t) takes into account the acceptable range of power density variation in the quiet zone. This factor may change over time. For example, the tolerance for power density loss may be different in different communication states.

[0039] It can be understood that the method for determining the quiet zone size of the test compact field in other scenarios can refer to the above examples, but is not limited to the above examples.
