[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311165681.2 filed on September 8, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a receiving performance testing method, apparatus, terminal, and network-side equipment. Background Art

[0004] In related technologies, in order to reduce the power consumption of the terminal, a low-power receiving module is introduced into the terminal, such as a low-power wake-up receiver (Low Power Wake Up Radio, LP-WUR) or an almost zero-power receiver (Almost Zero Power Wake Up Radio, AZP-WUR). The terminal turns on the low-power receiving module in an energy-saving state to listen for a low-power wake-up signal (Low Power Wake Up Signal, LP-WUS), while the main communication module of the terminal (or called the main receiving module or main receiver) is in an off state or a sleep state. When downlink data arrives, the network side device will send a wake-up signal to the terminal. After the terminal monitors the wake-up signal through the low-power receiving module, it triggers the main communication module to turn on or be awakened after relevant judgment.

[0005] Receiver sensitivity imbalance is an important indicator of terminal receiver performance. Currently, the evaluation method for terminal receiver reception performance (e.g., reception sensitivity) is only applicable when the terminal receiver operates in loopback mode. The receiver receives signals from the network-side device and feeds the signals back to the network-side device. However, low-power receiving modules do not operate in loopback mode. Therefore, the receiver sensitivity evaluation method in the related art is not applicable to evaluating the reception performance of low-power receiving modules. Therefore, in the related art, there is no corresponding solution for how to evaluate the reception performance of low-power receiving modules.

[0049] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0050] 1. Low-power receiving module

[0051] A low-power receiving module, such as a low-power wake-up receiver or a near-zero power receiver, has a basic principle that the receiving end of the terminal includes a first module and a second module, as shown in Figure 2. The first module is a main communication module (or called a main receiving module or a main receiver or a main radio frequency (Main Radio) module, etc.), which is used for sending and receiving mobile communication data, and the second module is a low-power receiving module (also called a low-power wake-up receiving module or a low-power receiving module), which is used to receive the above-mentioned wake-up signal. The terminal turns on the low-power receiving module in an energy-saving state to monitor the low-power wake-up signal and the main communication module is turned off or enters a sleep state. When downlink data arrives, the network will send a wake-up signal to the terminal. After the terminal monitors the wake-up signal through the low-power receiving module, it triggers the main communication module from off to on or wakes up after a series of judgments, and at this time the low-power receiving module enters a closed state from a working state. The low-power wake-up receiving module can be turned on continuously or intermittently, and can receive a low-power wake-up signal when it is turned on.

[0052] 2. Low power wake-up signal

[0053] To reduce terminal reception activity in standby mode, effectively shutting down the radio frequency (RF) and baseband module (e.g., baseband modem) to significantly reduce power consumption during communication reception, a near-zero-power receiver can be incorporated into the terminal's receiving module. This near-zero-power receiver eliminates the complex signal detection (such as amplification, filtering, and quantization) required by the RF module and the signal processing required by the baseband module, relying solely on passive matched filtering and low-power signal processing.

[0054] On the base station side, by triggering a wake-up signal on demand, the near-zero-power receiver can be activated to receive the activation notification, thereby triggering a series of processes within the terminal, such as turning on the RF transceiver and baseband processing modules.

[0055] This wake-up signal is typically a simple on-off keying signal. The time domain pattern of the on-off keying signal is shown in Figure 3. The receiver can detect the wake-up notification through simple energy detection and, possibly, sequence detection and recognition. Furthermore, while the terminal activates a low-power wake-up receiver to receive the wake-up signal, the main receiving module can enter sleep mode or shut down to maintain a low power consumption level, thereby saving power by receiving the wake-up signal. The wake-up signal can alert the receiver to the presence of a physical downlink control channel transmission or other communication.

[0056] 3. Receiver sensitivity

[0057] Receiver sensitivity (eg, reference sensitivity (REFSENS)) is the most basic and important indicator for measuring terminal receiver performance. Receiver sensitivity is defined as the RF power in the reference measurement channel (RMC) meeting a throughput of ≥ 95%.

[0058] Receiver sensitivity is assessed by setting the terminal in loopback mode. The terminal establishes a connection with a base station simulator on a test channel. The base station simulator sends a downlink test signal (reference measurement channel). The terminal receiver demodulates the received test signal and provides an acknowledgment (ACK) or negative acknowledgment (NACK) feedback. The base station simulator continuously reduces the downlink signal power until the terminal's receive throughput reaches 95% of the theoretical maximum throughput. The downlink power received by the terminal at this point is recorded.

[0059] The following describes in detail the receiving performance testing method provided in the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0060] Please refer to FIG4 , which is a flowchart of a receiving performance testing method provided in an embodiment of the present application. The method can be executed by a terminal, as shown in FIG4 , and includes the following steps:

[0061] Step 401: The terminal receives a first wake-up signal through a low-power receiving module.

[0062] In this embodiment, the low-power receiving module may also be referred to as a low-power wake-up receiver or a near-zero-power receiver. For example, the terminal may receive a first wake-up signal sent by a network-side device through the low-power receiving module, where the network-side device may be a test device or a simulation device, for example, a base station simulator.

[0063] The first wake-up signal is a wake-up signal for testing the receiving performance of the low-power receiving module. For example, the first wake-up signal can reuse the low-power wake-up signal (LP-WUS) in the related art or can be a specific wake-up signal, for example, a wake-up signal specially designed for testing. In addition, the first wake-up signal can include a first number of wake-up signals or a first duration of wake-up signals, wherein the first number and first duration can be reasonably set according to actual needs.

[0064] It should be noted that, when the first wake-up signal is received, the main communication module of the terminal may not be woken up.

[0065] Step 402: The terminal detects the first wake-up signal and obtains a detection result;

[0066] The detection result is used to calculate the reception error rate index value of the first wake-up signal, and the reception performance index value of the low-power receiving module is determined according to the reception power of the first wake-up signal whose reception error rate index value meets the preset conditions.

[0067] In this embodiment, the above-mentioned reception error rate index value can be used to characterize the reception status of the above-mentioned low-power receiving module for the first wake-up signal. Exemplarily, the above-mentioned reception error rate index value may include but is not limited to at least one of the block error rate (BLER), bit error rate (BER), and miss detection rate (Misdetection Ratio).

[0068] The above-mentioned detection of the first wake-up signal, for example, can perform sequence detection on the first wake-up signal to obtain a sequence detection result, and then compare the sequence detection result with the transmission sequence corresponding to the above-mentioned first wake-up signal to calculate the reception error rate index value; or the cyclic redundancy check (CRC) of the above-mentioned first wake-up signal can be calculated, and then the CRC calculated based on the received first wake-up signal can be compared with a reference CRC to calculate the reception error rate index value, wherein the reference CRC can be a CRC calculated based on the first wake-up signal on the sending side.

[0069] The reception performance index value of the low-power receiving module can be used to characterize the reception performance of the low-power receiving module. For example, the reception performance index value may include, but is not limited to, reception sensitivity or reference sensitivity. The reception error rate index value of the first wake-up signal satisfies a preset condition. For example, the reception error rate index value of the first wake-up signal is less than or equal to a preset threshold value. For example, the BLER of the first wake-up signal is less than or equal to 0.5%, 1%, 2%, 5%, or 10%. The reception performance index value of the low-power receiving module is determined based on the received power of the first wake-up signal when the reception error rate index value of the first wake-up signal satisfies the preset condition. That is, when the reception error rate index value of the first wake-up signal satisfies the preset condition, the reception performance index value of the low-power receiving module is determined based on the received power of the first wake-up signal. For example, the received power of the first wake-up signal is used as the reception sensitivity of the low-power receiving module.

[0070] It should be noted that, if the reception error rate index value of the first wake-up signal currently received by the low-power receiving module does not meet the preset conditions, the low-power receiving module may receive the first wake-up signal from the network-side device again until the reception error rate index value of the first wake-up signal received by the low-power receiving module meets the preset conditions. It should also be noted that the transmission power of the first wake-up signal sent by the network-side device to the terminal is different each time, and accordingly, the reception power of the first wake-up signal received by the terminal from the network-side device is different each time.

[0071] The receiving performance testing method provided in the embodiment of the present application is that the terminal receives a first wake-up signal through a low-power receiving module; the terminal detects the first wake-up signal to obtain a detection result; wherein the detection result is used to calculate the receiving error rate index value of the first wake-up signal, and the receiving performance index value of the low-power receiving module is determined according to the receiving power of the first wake-up signal whose receiving error rate index value meets a preset condition. In this way, the terminal receives the first wake-up signal sent by the network side device through the low-power receiving module and detects the first wake-up signal to obtain a detection result, and then calculates the receiving error rate index value of the first wake-up signal based on the detection result, and evaluates the receiving performance of the low-power receiving module based on the receiving power of the first wake-up signal when the receiving error rate index value of the first wake-up signal meets the preset condition. This not only realizes the evaluation of the receiving performance of the low-power receiving module, but also ensures the accuracy of the evaluation result.

[0072] Optionally, the first wake-up signal includes a low-power wake-up signal or a wake-up signal dedicated to testing.

[0073] In one embodiment, a low power consumption wake-up signal (LP-WUS) may be reused to test the receiving performance of the low power consumption receiving module, which is relatively simple to implement.

[0074] In another embodiment, a wake-up signal dedicated to testing may be designed to perform a receiving performance test on the low-power receiving module, which has high flexibility.

[0075] Optionally, the reception error rate indicator value includes at least one of the following: block error rate BLER, bit error rate BER, and missed detection rate.

[0076] Optionally, the receiving performance indicator value includes receiving sensitivity or reference sensitivity (REFSENS).

[0077] It should be noted that the receiving performance index value of the above-mentioned low-power receiving module can be obtained based on the conduction mode test, or can be obtained based on the air interface (Over the Air, OTA) mode test. Among them, the above-mentioned conduction mode can be understood as directly connecting the test equipment (network side equipment) and the tested equipment (terminal) with a radio frequency cable, so as to avoid the influence of the interference signal of space radiation on the test. The above-mentioned OTA mode can be understood as the transmission of signals between the test equipment and the tested equipment through the antenna. Exemplarily, the above-mentioned reference sensitivity may refer to the received power at the antenna port when the test is conducted in a conduction mode. Accordingly, the reference sensitivity of the above-mentioned low-power receiving module may refer to the received power of the first wake-up signal at the antenna port when the reception error rate index value of the first wake-up signal meets the preset conditions when the test is conducted in a conduction mode.

[0078] Optionally, the terminal detects the first wake-up signal, and obtains a detection result of the first wake-up signal, including at least one of the following:

[0079] The terminal performs sequence detection on the first wake-up signal to obtain a first detection result;

[0080] The terminal performs a load detection on the first wake-up signal to obtain a second detection result, wherein the load detection includes calculating a cyclic redundancy check (CRC) according to the first wake-up signal, and the second detection result includes the CRC;

[0081] The terminal detects an identifier of the terminal on the first wake-up signal to obtain a third detection result;

[0082] The terminal detects the identifier of the group to which the terminal belongs with respect to the first wake-up signal to obtain a fourth detection result.

[0083] The following examples illustrate the embodiments of this application:

[0084] In one embodiment, the terminal may perform sequence detection on the first wake-up signal to obtain a first detection result, such as a sequence detection result. In this case, the sequence detection result of the first wake-up signal may be compared with the sending sequence corresponding to the first wake-up signal to calculate the reception error rate index value of the first wake-up signal. This ensures that the calculated reception error rate index value can more accurately reflect the reception status of the first wake-up signal.

[0085] In another embodiment, the terminal may perform load detection on the first wake-up signal, such as calculating a CRC based on the first wake-up signal. For example, the CRC may be calculated based on each bit sequence of the first wake-up signal, each bit sequence including at least two bits, and then the CRC corresponding to each bit sequence may be compared with the reference CRC corresponding to each bit sequence to calculate the reception error rate index value of the first wake-up signal, wherein the reference CRC corresponding to the above-mentioned bit sequence may be a CRC calculated by the network-side device based on the transmission sequence corresponding to the bit sequence. This embodiment calculates the reception error rate index value of the first wake-up signal based on the CRC of the first wake-up signal, which can reduce the detection complexity while ensuring the accuracy of the calculated reception error rate index value.

[0086] In another embodiment, the terminal may detect the identification of the terminal on the first wake-up signal. For example, the identification of the terminal is carried on each bit sequence of the first wake-up signal, and the low-power receiving module may respectively detect the identification of the terminal on each bit sequence of the first wake-up signal. In this way, the reception error rate index value of the first wake-up signal can be calculated based on the number of terminal identifications accurately detected by the low-power receiving module. This embodiment calculates the reception error rate index value of the first wake-up signal based on the detection result of the identification of the terminal on the first wake-up signal. It can reduce the detection complexity while ensuring the accuracy of the calculated reception error rate index value.

[0087] In another embodiment, the terminal may detect the identifier of the group to which the terminal belongs on the first wake-up signal. For example, each bit sequence of the first wake-up signal carries the identifier of the group to which the terminal belongs, and the low-power receiving module may detect the identifier of the group to which the terminal belongs on each bit sequence of the first wake-up signal. In this way, the reception error rate index value of the first wake-up signal can be calculated based on the number of identifiers of the group to which the terminal belongs accurately detected by the low-power receiving module. This embodiment calculates the reception error rate index value of the first wake-up signal based on the detection result of the identifier of the group to which the terminal belongs on the first wake-up signal. This can reduce the detection complexity while ensuring the accuracy of the calculated reception error rate index value.

[0088] Optionally, the terminal detects the first wake-up signal to obtain a detection result, including:

[0089] The terminal detects each bit of the first wake-up signal respectively to obtain a detection result corresponding to each bit;

[0090] or,

[0091] The terminal detects each bit sequence of the first wake-up signal respectively to obtain a detection result corresponding to each bit sequence, where each bit sequence includes at least two bits of the first wake-up signal;

[0092] or,

[0093] The terminal detects all bits of the first wake-up signal to obtain a detection result corresponding to the first wake-up signal.

[0094] The following examples illustrate the embodiments of this application:

[0095] In one embodiment, the terminal detects each bit of the first wake-up signal respectively to obtain a detection result corresponding to each bit. In this way, detection is performed based on bit granularity, and each detection result can reflect the reception status of each bit.

[0096] In another embodiment, the terminal detects each bit sequence of the first wake-up signal respectively to obtain a detection result corresponding to each bit sequence. In this way, detection is performed based on the granularity of the bit sequence, and each detection result can reflect the reception status of each bit sequence.

[0097] In another embodiment, the terminal detects all bits of the first wake-up signal. This detection is performed based on the granularity of the entire first wake-up signal, and the detection result can reflect the reception status of the entire first wake-up signal. For example, the terminal performs sequence detection on all bits of the first wake-up signal to obtain a detection result, which includes detection values ​​for all bits of the first wake-up signal.

[0098] Optionally, the method further includes:

[0099] Calculating, by the terminal, a reception error rate indicator value of the first wake-up signal according to the detection result;

[0100] or,

[0101] The terminal indicates the detection result to the network side device through the main communication module;

[0102] or,

[0103] The terminal outputs the detection result.

[0104] In one embodiment, the terminal may calculate a reception error rate index value of the first wake-up signal based on the detection result. For example, in a case where the detection result includes a sequence detection result of the first wake-up signal, the sequence detection result of the first wake-up signal may be compared with a transmission sequence corresponding to the first wake-up signal to calculate the reception error rate index value of the first wake-up signal; or, in a case where the detection result includes a CRC of each bit sequence of the first wake-up signal, the CRC corresponding to each bit sequence is respectively compared with a reference CRC corresponding to each bit sequence to calculate the reception error rate index value of the first wake-up signal; or, in a case where the detection result includes a detection result of an identifier of the terminal carried on each bit sequence of the first wake-up signal, the reception error rate index value of the first wake-up signal may be calculated based on the number of identifiers of the terminal accurately detected by the low-power receiving module; or, in a case where the detection result includes a detection result of an identifier of the group to which the terminal belongs carried on each bit sequence of the first wake-up signal, the reception error rate index value of the first wake-up signal may be calculated based on the number of identifiers of the group to which the terminal belongs accurately detected by the low-power receiving module. Among them, the terminal can pre-store at least one of the following items before the test process starts: the sending sequence corresponding to the above-mentioned first wake-up signal, the reference CRC corresponding to each bit sequence of the above-mentioned first wake-up signal, the number of terminal identifiers carried by the above-mentioned first wake-up signal, and the number of identifiers of the group to which the terminal carries the above-mentioned first wake-up signal.

[0105] Furthermore, when the calculated reception error rate index value of the first wake-up signal meets a preset condition, the terminal may determine the reception performance index value of the low-power receiving module based on the reception power of the first wake-up signal, for example, using the reception power of the first wake-up signal as the reception sensitivity of the low-power receiving module. If the calculated reception error rate index value of the first wake-up signal does not meet the preset condition, the terminal may instruct the network-side device to send the first wake-up signal to the terminal again. For example, the terminal may instruct the network-side device to send the first wake-up signal to the terminal again through the main communication module.

[0106] In another embodiment, the terminal may indicate the detection result to the network-side device through the main communication module, and the network-side device may then calculate the reception error rate index value of the first wake-up signal based on the detection result. It should be noted that during the reception performance test of the low-power receiving module, the main communication module of the terminal may always be in an awake state, or the main communication module of the terminal may remain in an off state or a low-power sleep state and need to be awakened by the low-power receiving module.

[0107] In another embodiment, the terminal may output the detection result to an electronic device other than the network side device, and the electronic device may then calculate the reception error rate index value of the first wake-up signal based on the detection result. Furthermore, when the calculated reception error rate index value of the first wake-up signal meets the preset conditions, the electronic device may determine the reception performance index value of the low-power receiving module based on the reception power of the first wake-up signal, for example, using the reception power of the first wake-up signal as the reception sensitivity of the low-power receiving module, wherein the reception power of the first wake-up signal may also be output by the terminal to the electronic device. It should be noted that when the reception error rate index value of the first wake-up signal does not meet the preset conditions, the electronic device may instruct the network side device to send the first wake-up signal to the terminal again. For example, the electronic device may instruct the network side device to send the first wake-up signal to the terminal again through wired or wireless communication.

[0108] Optionally, before the terminal indicates the detection result to the network-side device through the main communication module, the method further includes:

[0109] The terminal wakes up the main communication module;

[0110] The terminal establishes a connection with the network side device through the main communication module.

[0111] Exemplarily, the main communication module can remain in a closed state or low-power sleep state while the low-power receiving module receives the first wake-up signal. The low-power receiving module needs to wake up the main communication module, which helps reduce the power consumption of the main communication module.

[0112] Optionally, the terminal waking up the main communication module includes:

[0113] Upon receiving the second wake-up signal sent by the network-side device, the terminal wakes up the main communication module;

[0114] or,

[0115] After the low-power receiving module completes receiving the first wake-up signal, the terminal wakes up the main communication module;

[0116] or,

[0117] The terminal wakes up the main communication module after a preset time period starting from a first moment, wherein the first moment is the moment when the low-power receiving module completes receiving the first wake-up signal or the moment when the low-power receiving module starts receiving the first wake-up signal.

[0118] In one embodiment, the main communication module can be awakened by a wake-up signal (second wake-up signal) sent by the network-side device. Specifically, upon receiving the second wake-up signal sent by the network-side device via the low-power receiving module, the terminal can wake up the main communication module, so that the main communication module can establish a connection with the network-side device to indicate the detection result to the network-side device.

[0119] In another embodiment, the terminal may autonomously determine the timing of waking up the main communication module. Specifically, the main communication module may be awakened after the low-power receiving module completes receiving the first wake-up signal, or the main communication module may be awakened after a preset time period starting from the first moment, wherein the above-mentioned preset time period may be reasonably set according to actual needs. Exemplarily, a timer may be started at the moment when the low-power receiving module starts receiving the first wake-up signal or ends receiving the first wake-up signal, and the timing duration of the timer is the above-mentioned preset time period. When the timer times out, the main communication module of the terminal is awakened.

[0120] Optionally, the terminal indicating the detection result to the network-side device through the main communication module includes:

[0121] Each time the terminal obtains a detection result from the low-power receiving module, the terminal sends the detection result to the network-side device through the main communication module;

[0122] or,

[0123] Each time the terminal obtains a detection result from the low-power receiving module, the terminal sends a random access channel response to the network side device through the main communication module;

[0124] or,

[0125] When the terminal obtains a detection result corresponding to a bit sequence of a first preset number or a first preset duration in the first wake-up signal, the terminal sends the detection result to the network side device through the main communication module.

[0126] In one embodiment, each time a detection result is obtained from the low-power receiving module, the main communication module may transmit the obtained detection result to the network-side device. For example, the low-power receiving module may transmit the detection result of a bit sequence of the first wake-up signal to the main communication module each time the low-power receiving module detects the detection result of the bit sequence. The main communication module may transmit the detection result of the bit sequence to the network-side device each time the main communication module receives the detection result of the bit sequence. This ensures the real-time reporting of the detection result.

[0127] In another embodiment, each time a detection result is obtained from the low-power receiving module, a random access channel (RACH) response can be sent to the network side device through the main communication module, so that the network side device can determine the detection result of the first wake-up signal based on the number of RACH responses. For example, the low-power receiving module can send a detection result to the main communication module each time a bit with a value of 1 is detected, and the main communication module sends a RACH response to the network side device each time a detection result is received. In this way, the network side device can obtain the number of bits with a value of 1 in the first wake-up signal based on the number of RACH responses sent by the terminal, and then compare the determined number of bits with a value of 1 with the number of bit sequences with a value of 1 in the transmission sequence of the first wake-up signal to calculate the reception error rate index value of the first wake-up signal. This method can save resource overhead for indicating the detection result to the terminal.

[0128] In another embodiment, when the detection results corresponding to the bit sequences of the first preset number or the first preset duration are obtained, the detection results can be sent to the network side device through the main communication module. For example, when the detection results corresponding to 10 bit sequences are obtained, the detection results corresponding to the 10 bit sequences are sent together to the network side device, or when the detection results corresponding to the bit sequences of 20 seconds are obtained, the detection results corresponding to the bit sequences of 20 seconds are sent together to the network side device. This helps to save resource overhead for indicating the detection results to the terminal.

[0129] Optionally, the terminal outputting the detection result includes:

[0130] The terminal outputs the detection result through an application program;

[0131] or,

[0132] The terminal exports the detection result through an external bus interface.

[0133] In one embodiment, the terminal can output the detection results to other electronic devices through an application. For example, the terminal can send the detection results to other electronic devices through an installed communication application, or the terminal can send the detection results to other electronic devices through an installed application dedicated to testing.

[0134] In another embodiment, the terminal may export the detection result to other electronic devices through an external vertical interface, for example, a Universal Serial Bus (USB) or a Type-C interface.

[0135] It should be noted that when other electronic devices obtain the detection results, they can calculate the reception error rate index value of the first wake-up signal based on the above detection results, or other electronic devices can send the above detection results to the network side device, and the network side device will calculate the reception error rate index value of the first wake-up signal based on the detection results.

[0136] Optionally, the first wake-up signal includes a first number of wake-up signals or a first duration of wake-up signals, wherein the first number is greater than or equal to a second preset number, and the first duration is greater than or equal to the second preset duration.

[0137] In this embodiment, the second preset number and the second preset duration can be reasonably set according to actual conditions. It is understood that by setting the first wake-up signal to include wake-up signals greater than or equal to the second preset number or to include wake-up signals greater than or equal to the second preset duration, the calculated reception error rate indicator value has a higher confidence level.

[0138] Optionally, the second preset number or the second preset time duration is determined according to a confidence requirement of a reception error rate index value.

[0139] In this embodiment, the above confidence requirement can be reasonably set according to actual needs, for example, the confidence level is greater than or equal to 95%. The second preset number or the second preset duration can be the minimum number or the shortest duration that can make the calculated reception error rate index value meet the confidence requirement.

[0140] Optionally, the reception error rate index value of the first wake-up signal meets a preset condition, including: the reception error rate index value of the first wake-up signal is less than or equal to a preset threshold value, or the reception error rate index value of the first wake-up signal is within a preset threshold range.

[0141] In this embodiment, the preset threshold value or preset threshold range can be reasonably set according to actual needs. For example, the preset threshold value can be 0.5%, 1%, 2%, 5%, or 10%, and the preset threshold range can be the preset threshold value ±X, where X can be reasonably set according to actual conditions, for example, 0.1%, 0.2%, etc. Exemplarily, the preset threshold range can be [0.5%-0.1%, 0.5%+0.1%], or [1%-0.2%, 1%+0.2%], etc.

[0142] It should also be noted that the low-power receiving module and the main communication module can be integrated together, for example, the low-power receiving module is a part of the main communication module, or can be two separate components.

[0143] Please refer to FIG5 , which is a flowchart of a receiving performance testing method provided in an embodiment of the present application. The method can be executed by a network-side device, as shown in FIG5 , including the following steps:

[0144] Step 501: A network-side device sends a first wake-up signal to a terminal, wherein the first wake-up signal is used to test the receiving performance of a low-power receiving module of the terminal.

[0145] Step 502: If the reception error rate indicator value of the first wake-up signal does not meet the preset condition, the network-side device adjusts the transmit power of the first wake-up signal and returns to the step of sending the first wake-up signal to the terminal until the reception error rate indicator value of the first wake-up signal meets the preset condition.

[0146] The receiving performance index value of the low-power receiving module is determined according to the receiving power of the first wake-up signal whose receiving error rate index value meets a preset condition.

[0147] For step 502, when the network side device determines that the reception error rate index value of the first wake-up signal does not meet the preset conditions, it can adjust the transmission power of the first wake-up signal and send the first wake-up signal to the terminal again with the adjusted transmission power. If the reception error rate index value of the first wake-up signal after adjusting the transmission power still does not meet the preset conditions, the transmission power of the first wake-up signal is adjusted again, and the first wake-up signal is sent to the terminal again with the adjusted transmission power until the reception error rate index value of the first wake-up signal after adjusting the transmission power meets the preset conditions.

[0148] It should be noted that the initial value of the transmission power of the above-mentioned first wake-up signal can be reasonably set according to actual conditions. When the reception error rate index value of the first wake-up signal does not meet the preset conditions, the network side device can adjust the transmission power of the first wake-up signal according to the preset power adjustment step. The above-mentioned preset power adjustment step is reasonably set according to actual conditions, for example, 0.5dB or 0.25dB.

[0149] Optionally, the first wake-up signal includes a low-power wake-up signal or a wake-up signal dedicated to testing.

[0150] Optionally, the reception error rate indicator value includes at least one of the following: block error rate BLER, bit error rate BER, and missed detection rate.

[0151] Optionally, the receiving performance indicator value includes receiving sensitivity or reference sensitivity.

[0152] Optionally, the method further includes:

[0153] The network side device receives a detection result of the first wake-up signal indicated by the terminal through the main communication module;

[0154] The network-side device determines a reception error rate indicator value of the first wake-up signal according to a detection result of the first wake-up signal.

[0155] It should be noted that the implementation method in which the network side device determines the reception error rate index value of the first wake-up signal based on the detection result of the first wake-up signal can be the same as the implementation method in which the terminal determines the reception error rate index value of the first wake-up signal based on the detection result of the first wake-up signal, which will not be repeated here.

[0156] Optionally, the network-side device receives a detection result of the first wake-up signal indicated by the terminal through the main communication module, including:

[0157] The network side device receives a detection result of the first wake-up signal sent by the terminal through the main communication module;

[0158] or,

[0159] The network-side device receives a random access channel response sent by the terminal through the main communication module, where the random access channel response is used to indicate a detection result of the first wake-up signal.

[0160] Optionally, after the network-side device sends the first wake-up signal to the terminal, the method further includes:

[0161] The network-side device sends a second wake-up signal to the terminal, wherein the second wake-up signal is used to wake up a main communication module of the terminal.

[0162] Optionally, the first wake-up signal includes a first number of wake-up signals or a first duration of wake-up signals, wherein the first number is greater than or equal to a second preset number, and the first duration is greater than or equal to the second preset duration.

[0163] Optionally, the second preset number or the second preset time duration is determined according to a confidence requirement of a reception error rate index value.

[0164] Optionally, the reception error rate index value of the first wake-up signal meets a preset condition, including: the reception error rate index value of the first wake-up signal is less than or equal to a preset threshold value, or the reception error rate index value of the first wake-up signal is within a preset threshold range.

[0165] It should be noted that the implementation of this embodiment can refer to the relevant description of the embodiment shown in Figure 4, and will not be repeated here.

[0166] The following examples illustrate the embodiments of the present application:

[0167] Example 1: To achieve a quick test, the main communication module is in an open or turned-on state and maintains a Radio Resource Control (RRC) connection state with the network-side device.

[0168] Step a1: The network side device sends a first number / first duration of wake-up signals, namely the first wake-up signal mentioned above. The first wake-up signal can be a specific wake-up signal or a conventional low-power wake-up signal.

[0169] It should be noted that when the network side device sends the first wake-up signal for the first time, it can be sent based on the initial power and parameter configuration.

[0170] Step a2: The low-power receiving module receives the first wake-up signal and performs detection, and indicates each detection result to the main communication module.

[0171] Step a3: The main communication module reports the detection results one by one, or after accumulating the second number / second duration of low-power wake-up signal detection indication information, reports them to the network side device in a unified manner.

[0172] Step a4: The network-side device counts the BLER of the first wake-up signal based on the detection result of the low-power receiving module receiving the first wake-up signal reported by the main communication module.

[0173] Step a5: The network-side device determines whether the BLER of the first wake-up signal reaches a preset threshold or is within a preset threshold range.

[0174] Step a6: If the preset threshold is not reached or is not within the preset threshold range, the network side device changes the transmit power of the first wake-up signal. For example, the transmit power of the first wake-up signal can be adjusted using a fixed step size such as 0.5dB or 0.25dB, and based on the adjusted transmit power, returns to step a1 until the BLER of the transmitted first wake-up signal reaches the preset threshold or is within the preset threshold range. The downlink signal power (the received power of the first wake-up signal whose BLER reaches the preset threshold or is within the preset threshold range) is the receiving sensitivity of the low-power receiving module.

[0175] Example 2: When the low-power receiving module performs wake-up signal measurement, the main communication module remains in the off state or low-power sleep state.

[0176] Step b1: The network-side device sends a first number / first duration of wake-up signals, namely, the first wake-up signal.

[0177] This step is the same as the above step a1 and will not be described in detail here.

[0178] Step b2: The low-power receiving module receives the first wake-up signal and performs detection, and the detection result is stored by the low-power receiving module or indicated to the main communication module for storage. During this process, the main communication module remains in a closed state or a low-power sleep state.

[0179] Step b3: After completing step b2, the network side device triggers the awakening of the main communication module (for example, sending a second wake-up signal to directly wake up the main communication module, or waking up the main communication module through a low-power receiving module). After waking up, the main communication module connects to the network side device and reports the detection results.

[0180] Or step b3 is: after completing step b2, the main communication module does not need to be triggered by the network side device, and the low-power receiving module starts the main communication module in time and connects to the network side device to report the detection results.

[0181] Alternatively, step b3 is: after completing step b2, exporting the test results through other means, such as a specific application or a UBS interface.

[0182] Step b4: The network side device counts the BLER of the first wake-up signal based on the detection result of the first wake-up signal reported by the main communication module to the network side device or the detection result of the first wake-up signal derived by other means.

[0183] Step b5: The network-side device determines whether the BLER of the first wake-up signal reaches a preset threshold or is within a preset threshold range.

[0184] Step b6: If the preset threshold is not reached or is not within the preset threshold range, the network side device changes the transmission power of the first wake-up signal, and based on the adjusted transmission power, returns to execute step b1 until the BLER of the sent first wake-up signal reaches the preset threshold or is within the preset threshold range. The downlink signal power (the received power of the first wake-up signal whose BLER reaches the preset threshold or is within the preset threshold range) is the receiving sensitivity of the low-power receiving module.

[0185] Example 3: While the low-power receiving module is measuring the wake-up signal, the main communication module remains in the off state or low-power sleep state.

[0186] Step c1: The network-side device sends a first number / first duration of wake-up signals, namely, the first wake-up signal.

[0187] This step is the same as the above step a1 and will not be described in detail here.

[0188] Step c2: The low-power receiving module receives the wake-up signal and performs detection, and indicates the detection result to the main communication module.

[0189] Step c3: The main communication module sends RACH responses to the network side device one by one based on the detection result of step c2.

[0190] Step c4: The network-side device counts the BLER of the first wake-up signal based on the number of RACHs sent by the main communication module.

[0191] Step c5: The network-side device determines whether the BLER of the first wake-up signal reaches a preset threshold or is within a preset threshold range.

[0192] Step c6: If the preset threshold is not reached or is not within the preset threshold range, the network side device changes the transmission power of the first wake-up signal, and based on the adjusted transmission power, returns to execute step c1 until the BLER of the transmitted first wake-up signal reaches the preset threshold or is within the preset threshold range. The downlink signal power (the received power of the first wake-up signal whose BLER reaches the preset threshold or is within the preset threshold range) is the receiving sensitivity of the low-power receiving module.
