Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method and apparatus for determining frequency points. Background Art

[0002] Bluetooth is a radio technology that supports short-distance communication between devices and can perform wireless information exchange among many devices including mobile phones, laptop computers, and related peripherals. Using Bluetooth technology can effectively simplify communication between mobile terminal devices, making data transmission faster and more efficient, and broadening the path for wireless communication.

[0003] Bluetooth wireless communication uses the 2.4 GHz frequency band. However, in addition to Bluetooth, the 2.4 GHz frequency band can also support other wireless protocols, such as Wireless Fidelity (Wi-Fi), Ultra Wide Band (UWB), Zigbee, 2.4 GHz cordless phones, etc. These wireless protocols supported by the 2.4 GHz frequency band will occupy the frequency points available for Bluetooth. To ensure reliable data transmission, Bluetooth has a frequency agility characteristic. The frequency agility characteristic refers to the characteristic of quickly changing the communication frequency in the presence of interference to avoid interference and ensure data transmission.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0026] The frequency point determination method proposed in the embodiments of this application can be executed by a terminal device. A terminal device is a device with wireless transceiver functions, and can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal device, in-vehicle terminal device, industrial control terminal device, UE unit, UE station, mobile station, remote station, remote terminal device, mobile device, UE terminal device, wireless communication device, UE agent, or UE device, etc. The terminal device can be fixed or mobile.

Among them, the chip module can include a chip and can also include other discrete devices. The embodiments of this application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0027] Please refer to Figure 1 , which is a schematic flowchart of a frequency point determination method provided by an embodiment of the present application. As Figure 1 shown, the frequency point determination method may include but is not limited to the following steps:

[0028] S101. Receive a signal.

[0029] The terminal device in the embodiment of the present application has a Bluetooth communication function. When the terminal device receives a signal through Bluetooth, the preliminary operating frequency points can be determined through steps S102 and S103.

[0030] S102. Perform channel quality evaluation on multiple first frequency points to obtain evaluation results of the multiple first frequency points; the absolute value of the frequency difference between each first frequency point and the center frequency point of the carrier carrying the signal is less than a first threshold; the multiple first frequency points include the center frequency point.

[0031] Among them, the fact that the absolute value of the frequency difference between each first frequency point and the center frequency point of the carrier carrying the signal is less than the first threshold may indicate that: the multiple first frequency points include the center frequency point and the frequency points within a range near the center frequency point.

[0032] Bluetooth adopts the dynamic frequency-hopping spread spectrum (FHSS) technology, with 1600 hops per second. Currently, 79 operating frequency points (from 2402 MHz to 2480 MHz) are configured for Bluetooth communication. Refer to Figure 2 , which is a schematic diagram of a scenario for determining multiple first frequency points within the frequency range from 2402 MHz to 2480 MHz. Figure 2 In, A to E represent frequency ranges, and the small black dots represent a frequency point. As Figure 2 shown, the center frequency point of the carrier carrying the signal received in S101 is a frequency point in region C, and 6 frequency points near the center frequency point can also be determined as the first frequency points. It should be noted that Figure 2 in the frequency range from 2402 MHz to 2480 MHz is divided into 5 smaller frequency ranges for illustration, and each frequency range shown by A to E includes 2 frequency points for illustration, not that there are actually only 2 frequency points.

[0033] Optionally, the first threshold may be agreed upon by a protocol; alternatively, the first threshold may be determined by the terminal device itself. Exemplarily, the terminal device determines the first threshold based on one or more of the following: the remaining battery power of the terminal device, the frequency of data transmission using the Bluetooth function by the terminal device, and the evaluation results of multiple frequency points obtained from the previous channel quality assessment by the terminal device. When the remaining battery power of the terminal device is more, the first threshold may be larger; conversely, when the remaining battery power of the terminal device is less, the first threshold may be smaller. When the frequency of data transmission using the Bluetooth function by the terminal device is higher, the first threshold may be larger; conversely, when the frequency of data transmission using the Bluetooth function by the terminal device is lower, the first threshold may be smaller. The evaluation result of a frequency point includes a signal quality evaluation value. When the average value of the signal quality evaluation values of multiple frequency points obtained from the previous channel quality assessment by the terminal device is larger, the first threshold may be smaller; conversely, when the average value is smaller, the first threshold may be larger. The larger the first threshold, the more frequency points are measured in the channel quality assessment, so that a channel with better channel quality can be selected from the channels corresponding to more frequency points for Bluetooth data transmission, thus better ensuring the communication quality. Exemplarily, the first threshold may be 20 MHz.

[0034] Optionally, performing channel quality assessment on multiple first frequency points includes: performing fast Fourier transform calculation on each of the multiple first frequency points; or determining the Received Signal Strength Indication (RSSI) of the channel corresponding to each of the multiple first frequency points. Optionally, the evaluation result of a frequency point may include a signal quality evaluation value. Exemplarily, the evaluation results of multiple first frequency points include the RSSI values of the channels corresponding to each of the first frequency points.

[0035] Optionally, the number of first frequency points may be agreed upon by a protocol. For example, the number of first frequency points is an integer N greater than 1. At this time, the terminal device determines N frequency points among the frequency points whose absolute value of the frequency difference from the aforementioned center frequency point is less than the first threshold as the first frequency points. For example, among the frequency points whose absolute value of the frequency difference from the aforementioned center frequency point is less than the first threshold, N frequency points with a smaller (or larger) absolute value of the frequency difference from the center frequency point are determined as the first frequency points.

[0036] Alternatively, the number N of the first frequency points is determined by the terminal device itself. Exemplarily, the terminal device determines the first threshold according to one or more of the following: the remaining power of the terminal device, the frequency of data transmission using the Bluetooth function by the terminal device, and the evaluation results of multiple frequency points obtained in the previous channel quality assessment of the terminal device. When the remaining power of the terminal device is more, N can be larger; conversely, when the remaining power of the terminal device is less, N can be smaller. When the frequency of data transmission using the Bluetooth function by the terminal device is higher, N can be larger; conversely, when the frequency of data transmission using the Bluetooth function by the terminal device is lower, N can be smaller. The evaluation result of a frequency point includes a signal quality evaluation value. When the average value of the signal quality evaluation values of multiple frequency points obtained in the previous channel quality assessment of the terminal device is larger, N can be smaller; conversely, when the average value is smaller, N can be larger. The larger N is, the more first frequency points are measured in the channel quality assessment, so that a channel with better channel quality can be selected from the channels corresponding to more first frequency points for Bluetooth data transmission, thereby better ensuring the communication quality.

[0037] S103. Determine multiple preliminary working frequency points from the multiple first frequency points according to the evaluation results of the multiple first frequency points; wherein, the evaluation result of each preliminary working frequency point satisfies a preset condition, and the absolute value of the frequency difference between each preliminary working frequency point and the foregoing center frequency point is greater than a second threshold; the second threshold is less than the first threshold.

[0038] 79 working frequency points (from 2402 MHz to 2480 MHz) are configured for Bluetooth communication, but in actual situations, there are interfering frequency points among the 79 working frequency points. In the embodiments of the present application, the working frequency point is a frequency point actually available for Bluetooth communication, and this working frequency point can also be called a hopping frequency point. Optionally, multiple working frequency points actually available for Bluetooth communication can be stored in a working frequency point table, and this working frequency point table can also be called a hopping table (channel map). The hopping table does not include interfering frequency points. The terminal device selects a hopping point in the hopping table for Bluetooth communication, which is beneficial to ensuring the Bluetooth communication quality. In the embodiments of the present application, the preliminary working frequency point is a frequency point actually available for Bluetooth communication prepared in advance for the terminal device when the current hopping table does not meet the usage conditions. That is, when the current hopping table does not meet the usage conditions, the terminal device can replace the frequency points in the current hopping table with the multiple determined preliminary working frequency points; or, when the current hopping table does not meet the usage conditions, the terminal device switches from the current hopping table to the multiple preliminary working frequency points, that is, uses the multiple preliminary working frequency points for Bluetooth communication.

[0039] Among them, the absolute value of the frequency difference between each preliminary working frequency point and the aforementioned center frequency point is greater than a second threshold, and the second threshold is less than the first threshold, which may indicate that the multiple preliminary working frequency points include the frequency points among the multiple first frequency points that are relatively far from the aforementioned center frequency point. The second threshold may be, for example, 10 MHz. In this way, it is possible to avoid the preliminary working frequency points being concentrated near the center frequency point, making the preliminary working frequency points relatively dispersed. Thus, in the case where there is interference in some preliminary working frequency points, the communication quality can still be ensured through other preliminary working frequency points. Refer to Figure 3 , for the scenario schematic diagram of determining multiple preliminary working frequency points based on the multiple first frequency points determined in Figure 2 . As shown in Figure 3 , 4 frequency points that are relatively far from the aforementioned center frequency point among the 7 first frequency points can be determined as preliminary working frequency points. Optionally, the number of preliminary working frequency points can be agreed upon by the protocol. For example, the number of preliminary working frequency points is an integer M greater than 1. The terminal device determines M frequency points that are relatively far from the aforementioned center frequency point among the N first frequency points as preliminary working frequency points.

[0040] The evaluation result may include a signal quality evaluation value, and the preset condition may include: the signal quality evaluation value of each preliminary working frequency point is greater than a third threshold. The third threshold can be agreed upon by the protocol.

[0041] Optionally, refer to Figure 4 , the specific process for the terminal device to determine multiple preliminary working frequency points from the multiple first frequency points according to the evaluation results of the multiple first frequency points may include but is not limited to steps S103a to S103d:

[0042] S103a. According to the evaluation results of the multiple first frequency points, determine the frequency point types of the multiple first frequency points. The frequency point types are the first type or the second type.

[0043] Among them, the frequency point type of the frequency point whose signal quality evaluation value is greater than a fourth threshold may be the first type, and the frequency point type of the frequency point whose signal quality evaluation value is less than or equal to the fourth threshold may be the second type; the fourth threshold is less than the aforementioned third threshold. That is, the channel quality corresponding to the frequency points of the first type is better, and the channel quality corresponding to the frequency points of the second type is worse. The frequency points of the first type may be frequency points that cannot be actually used for Bluetooth communication, and the frequency points of the second type may be frequency points that can be actually used for Bluetooth communication.

[0044] S103b. Determine multiple second frequency points of the first type from the multiple first frequency points.

[0045] The terminal device removes the frequency points of the second type from the multiple first frequency points to obtain the multiple second frequency points.

[0046] S103c. Determine multiple third frequency points from the multiple second frequency points whose signal quality evaluation values are greater than a third threshold.

[0047] The terminal device selects, from the multiple second frequency points, the frequency points whose signal quality evaluation values are greater than the third threshold as the third frequency points, and then determines the preliminary working frequency points from the third frequency points. It can be understood that the signal quality evaluation value of the channel corresponding to the third frequency point is greater than the third threshold. In this way, by using the preset working frequency point for Bluetooth communication, the Bluetooth communication quality can be ensured.

[0048] S103d. Determine multiple preliminary working frequency points from the multiple third frequency points, where the absolute value of the frequency difference between each of the preliminary working frequency points and the aforementioned center frequency point is greater than a second threshold.

[0049] It should be noted that the multiple preliminary working frequency points determined in the embodiments of the present application can be: the frequency points that are prepared in advance for the terminal device and can actually be used for Bluetooth communication when the current hopping table of the terminal device does not meet the usage conditions (Scenario 1); or the frequency points that are prepared in advance for the Bluetooth device and can actually be used for Bluetooth communication when the current hopping table of the Bluetooth device does not meet the usage conditions (Scenario 2). In Scenario 2, the terminal device can be a device associated with the Bluetooth device. Exemplarily, the Bluetooth device is a smart watch, and the terminal device is a mobile phone paired with the smart watch.

[0050] Optionally, in step S103 or step S103d, the terminal device can also use the determined multiple preliminary working frequency points as the working frequency points for Bluetooth communication. Exemplarily, if it is applied to Scenario 2, when the current hopping table does not meet the usage conditions, the terminal device can use the determined multiple preliminary working frequency points as the actual working frequency points for Bluetooth communication. Among them, the current hopping table not meeting the usage conditions can include: the number of frequency points of the first type in the current hopping table is less than a preset value (such as the preset value is equal to the aforementioned M), that is, the number of frequency points that can actually be used for Bluetooth communication in the current hopping table is less than the preset value.

[0051] Optionally, when the terminal device receives a signal via Bluetooth, it can evaluate the channel quality of multiple fourth frequency points; if the average channel quality of more than a preset proportion of the multiple fourth frequency points is less than a preset quality value, the terminal device executes steps S102 - S103 to determine multiple preset operating frequency points. Among them, the absolute value of the frequency difference between each fourth frequency point and the center frequency point of the carrier carrying the signal is less than a fifth threshold, and the fifth threshold is less than the aforementioned first threshold. The fact that the absolute value of the frequency difference between each fourth frequency point and the center frequency point of the carrier carrying the signal is less than the fifth threshold can indicate that the multiple fourth frequency points include the center frequency point and its nearby frequency points, and the center frequency point and its nearby frequency points are interfered. When the center frequency point and its nearby frequency points are interfered, the probability that the current frequency hopping table does not meet the usage conditions is very high. At this time, executing steps S102 - S103 can more timely determine multiple preset operating frequency points, so that when the current frequency hopping table actually does not meet the usage conditions, the preset operating frequency points can be used as the actual operating frequency points for Bluetooth communication, which is beneficial to ensuring the Bluetooth communication quality.

[0052] By implementing the embodiments of the present application, on the one hand, it can be avoided that the preliminary operating frequency points are concentrated near the center frequency point, making the preliminary operating frequency points relatively dispersed. Thus, in the case where some preliminary operating frequency points are interfered, the communication quality can still be ensured through other preliminary operating frequency points. On the other hand, the multiple determined preliminary operating frequency points are all frequency points with good channel quality evaluated through channel quality assessment. In this way, it can be avoided to select unevaluated frequency points for Bluetooth communication in the case where the center frequency point and its nearby frequency points are interfered, which is beneficial to ensuring the Bluetooth communication quality.
