[0030] Currently, frequency division duplex (FDM) may be used for communication in weak network scenarios. However, the duty cycle of FDM in weak network scenarios can reach 100%, resulting in high radio frequency power consumption and severely affecting the standby time of electronic devices.

[0031] To address the aforementioned problems, this application proposes a frequency band control method. The following embodiments are provided to further illustrate this application:

[0032] Please see Figure 1 , Figure 1 This is a flowchart illustrating a frequency band control method according to an exemplary embodiment of this application. The frequency band control method can be executed by electronic devices such as mobile phones, computers, messaging devices, tablets, and personal digital assistants, and is applicable to mobile communication scenarios such as 4G, 5G, and 6G. The method may include the following steps:

[0033] Step 102: Both the time-division signal and the frequency-division signal are within the weak network signal range.

[0034] In this step, the electronic device can measure and obtain the time division signal of the time division duplex frequency band in the wireless communication process through the built-in communication module and signal processing algorithm such as the antenna, the radio frequency front end, and the baseband processor. The time division signal reflects the signal quality under the time division duplex frequency band.

[0035] In addition, the frequency division signal of the frequency division duplex frequency band is measured and obtained, and the frequency division signal reflects the signal quality under the frequency division duplex frequency band.

[0036] The electronic device can consider the signal strength, transmission rate, and packet loss rate of the time division signal and the frequency division signal to determine whether the time division signal and the frequency division signal are both in the weak network signal range. If the time division signal and the frequency division signal are both in the weak network signal range, it can be determined that the current communication scenario is a weak network scenario.

[0037] The time division signal is a signal on the time division duplex frequency band. The frequency division signal is a signal on the frequency division duplex frequency band. The weak network signal range can be a pre-set range, which is used to represent a state of weak signal, slow network speed, or unstable network, which may affect the stability and speed of communication.

[0038] The weak network scenario is a network environment with low signal strength, poor signal-to-noise ratio, and unstable communication quality, for example, a wireless communication scenario in a densely populated urban area, an underground parking lot, or a region with serious signal attenuation between high-rise buildings.

[0039] The time division duplex frequency band (TDD band) refers to the radio frequency range used for time division duplex (TDD) technology. The frequency division duplex frequency band (FDD band) refers to the radio frequency range used for frequency division duplex technology.

[0040] Time division duplex is a technology that assigns alternating time slots for transmission and reception operations to achieve bidirectional communication within a single frequency band. The duty cycle of time division duplex in a weak network scenario is low, with a maximum of 40%. Step 104: If the frequency division signal parameter does not exceed the sum of the time division signal parameter and the pre-set threshold, use the time division duplex frequency band for communication; the pre-set threshold is used to limit the difference range of the time division signal parameter and the frequency division signal parameter.

[0041] In this step, the electronic device can compare the sum of the frequency division signal parameter of the frequency division signal and the time division signal parameter of the time division signal with the pre-set threshold. If the frequency division signal parameter does not exceed the sum of the time division signal parameter and the pre-set threshold, the electronic device uses the time division duplex frequency band for communication.

[0042] In the comparison process of the signal parameter, the pre-set threshold can be added to limit the difference range of the time division signal parameter and the frequency division signal parameter.

[0043] When the frequency division signal parameter of the frequency division duplex frequency band exceeds the sum of the time division signal parameter and the preset threshold value, it indicates that the signal strength of the frequency division duplex frequency band is much higher than the signal strength of the time division duplex frequency band, and increasing the preset threshold value can avoid a significant reduction in communication quality due to the use of the time division duplex frequency band to reduce radio frequency power consumption.

[0044] The time division signal parameter is used to identify the signal strength of the time division signal of the time division duplex frequency band, and can be a reference signal received power (RSRP), a reference signal received quality (RSRQ), etc. of the time division duplex frequency band.

[0045] The frequency division signal parameter is used to identify the signal strength of the frequency division signal of the frequency division duplex frequency band, and can be a reference signal received power, a reference signal received quality, etc. of the frequency division duplex frequency band.

[0046] The preset threshold value is used to limit the difference range of the time division signal parameter and the frequency division signal parameter, and can be a pre-set value, for example: 3, 5, etc.

[0047] Please refer to Figure 2 , Figure 2 is a schematic diagram of current data of different frequency bands according to an exemplary embodiment of the present application. For example, the frequency division duplex frequency band includes: B1, N1, B3 and B8, and the time division duplex frequency band includes: N78, N41 and B40.

[0048] Taking a mobile phone running at a 4V voltage as an example, Figure 2 The current data of the mobile phone corresponding to different frequency bands is shown. In a weak network scenario where the reference signal received power is less than or equal to -112dBm, different models of mobile phones consume different current data when communicating through different frequency bands during the use of video, game and other application programs by users.

[0049] Specifically, Figure 2 The relationship between the corresponding different frequency bands and the current data can be as shown in Table 1:

[0050] Table 1 Relationship between different frequency bands and current data (mA)

[0051]

[0052] The current data affects the power consumption of the power amplifier (PA) of the mobile phone, and the PA power consumption can directly affect the radio frequency power consumption of the electronic device. Through the above analysis of the measured data at 4V voltage, compared with the average current data of the frequency division duplex frequency band, the average current data of the time division duplex frequency band can be reduced by 200mA, and the average PA power consumption of the time division duplex frequency band is reduced by 4V*200mA=800mW.

[0053] Therefore, by using the frequency band control method of the embodiment, the PA power consumption can be reduced by 800mW in the weak network scenario, the radio frequency power consumption is greatly reduced, and the use time of the user for the application program can be prolonged by about 5.5 hours.

[0054] It can be understood that the relationship between the different frequency bands and the current data shown in Table 1 and Figure 2 It can be understood that the relationship between the different frequency bands and the current data shown in Table 1 and

[0055] In an embodiment, the weak network signal range can include -100dBm to -120dBm. Among them, -100dBm is used to identify the maximum threshold value of the signal strength in the weak network scenario, and -120dBm is used to identify the minimum threshold value of the signal strength supporting the communication function in the weak network scenario.

[0056] As described above, by setting the signal range to -100dbm to -120dbm, the power consumption reduction benefit brought by using the time division duplex frequency band for communication in the weak network scenario can be ensured while ensuring that the frequency band in the range is sufficient to maintain the basic communication demand.

[0057] In an embodiment, in the case that at least one of the time division signal parameter and the frequency division signal parameter is not in the weak network signal range, it can be determined that the current communication scenario is not in the weak network scenario.

[0058] The electronic device can compare the time division signal parameter and the frequency division signal parameter, and use the time division duplex frequency band or the frequency division duplex frequency band with higher signal strength for communication.

[0059] If the time division signal parameter is higher than the frequency division signal parameter, the time division duplex frequency band is used for communication. If the frequency division signal parameter is higher than the time division signal parameter, the frequency division duplex frequency band is used for communication.

[0060] As described above, by comparing the time division signal parameter and the frequency division signal parameter in the case that at least one of the time division signal parameter and the frequency division signal parameter is not in the weak network signal range, using the time division duplex frequency band or the frequency division duplex frequency band with higher signal strength to communicate, the communication quality and the data transmission rate can be improved, and the error rate of data transmission can be reduced.

[0061] The frequency band control method of the embodiment can greatly reduce the radio frequency power consumption consumed by communication and improve the use time of the electronic device by using the time division duplex frequency band with low duty cycle to communicate in the case that the time division signal and the frequency division signal are both in the weak network signal range and the frequency division signal parameter does not exceed the sum of the time division signal parameter and the preset threshold.

[0062] In the foregoing embodiments, the use of the time division duplex frequency band to communicate in the case that the frequency division signal parameter does not exceed the sum of the time division signal parameter and the preset threshold in the weak network scenario is introduced. In the following embodiments, the communication mode in the weak network scenario will be described in more detail, and any of the above embodiments can be applied.

[0063] In an embodiment, the electronic device can receive wireless signals from various base stations in the surrounding environment through the communication module built-in.

[0064] The electronic device performs frequency band identification on each wireless signal from each base station based on the frequency characteristics of the wireless signal, the base station broadcast, and other information, and monitors to obtain all frequency bands existing in the environment where the electronic device is located.

[0065] The electronic device obtains the time division signal parameter and the frequency division signal parameter in the case that the time division duplex frequency band and the frequency division duplex frequency band exist at the same time in all frequency bands.

[0066] As described above, by performing frequency band identification on each wireless signal from each base station, monitoring to obtain all frequency bands existing in the environment where the electronic device is located, and obtaining the time division signal parameter and the frequency division signal parameter in the case that the time division duplex frequency band and the frequency division duplex frequency band exist at the same time in all frequency bands, it is convenient to subsequently cope with the weak network scenario in time and use the time division duplex frequency band to communicate, thereby reducing the radio frequency power consumption.

[0067] In an embodiment, the time division signal parameter includes the reference signal received power (TDD band RSRP) of the time division duplex frequency band. The frequency division signal parameter includes the reference signal received power (FDD band RSRP) of the frequency division duplex frequency band.

[0068] In the case that the reference signal received power of the time division duplex frequency band and the reference signal received power of the frequency division duplex frequency band are both in the weak network signal range, it is determined that the time division signal and the frequency division signal are both in the weak network signal range, and the current communication scenario is in the weak network scenario.

[0069] If the reference signal received power of the frequency division duplex frequency band does not exceed the sum of the reference signal received power of the time division duplex frequency band and the preset threshold value, the electronic device can compare the reference signal received power of the frequency division duplex frequency band and the reference signal received power of the time division duplex frequency band.

[0070] If the reference signal received power of the frequency division duplex frequency band is greater than or equal to the reference signal received power of the time division duplex frequency band, the electronic device can increase the reference signal received power of the time division duplex frequency band by a compensation value through software in the electronic device.

[0071] The reference signal received power of the time division duplex frequency band after the compensation value is increased is higher than the reference signal received power of the frequency division duplex frequency band. The electronic device uses the time division duplex frequency band after the compensation value is increased for communication.

[0072] The compensation value can be a preset fixed value, or can be set according to the difference between the reference signal received power of the frequency division duplex frequency band and the reference signal received power of the time division duplex frequency band, which is not limited in the embodiments of the present application.

[0073] If the reference signal received power of the frequency division duplex frequency band is less than the reference signal received power of the time division duplex frequency band, the electronic device can use the time division duplex frequency band with higher reference signal received power for communication.

[0074] As described above, by increasing the reference signal received power of the time division duplex frequency band by a compensation value when the reference signal received power of the frequency division duplex frequency band is greater than or equal to the reference signal received power of the time division duplex frequency band, the reference signal received power after the compensation value is increased is higher than the reference signal received power of the frequency division duplex frequency band, which ensures that the time division duplex frequency band after the compensation value is increased is used for communication, avoids selecting the frequency division duplex frequency band for communication in a weak network scenario, and thus reduces the radio frequency power consumption of the electronic device.

[0075] In an embodiment, if the frequency division signal parameter exceeds the sum of the time division signal parameter and the preset threshold value when both the time division signal parameter and the frequency division signal parameter are in the weak network signal range, the frequency division duplex frequency band is used for communication.

[0076] As described above, by using the frequency division duplex frequency band for communication when the frequency division signal parameter exceeds the sum of the time division signal parameter and the preset threshold value when both the time division signal parameter and the frequency division signal parameter are in the weak network signal range, the signal quality and communication stability in the weak network scenario can be ensured.

[0077] In order to further introduce the frequency band control process, Figure 3A flow chart of another frequency band control method is shown. Taking time division signal parameter, reference signal received power of time division duplex frequency band (TDD band RSRP), and frequency division signal parameter, reference signal received power of frequency division duplex frequency band (FDD band RSRP) as examples, the frequency band control method can include the following steps:

[0078] Step 302: The electronic device performs frequency band identification on each wireless signal from each base station, and monitors all frequency bands existing in the environment where the electronic device is located.

[0079] Step 304: In the case where time division duplex frequency bands and frequency division duplex frequency bands exist in all frequency bands, TDD band RSRP and FDD band RSRP are obtained.

[0080] Step 306: It is judged whether TDD band RSRP and FDD band RSRP are both in the weak network signal range.

[0081] In this step, the electronic device judges whether TDD band RSRP of the time division signal and FDD band RSRP of the frequency division signal are both in the weak network signal range.

[0082] If at least one of TDD band RSRP and FDD band RSRP is not in the weak network signal range, step 308 is continued to be executed;

[0083] If TDD band RSRP and FDD band RSRP are both in the weak network signal range, step 312 is executed.

[0084] Step 308: TDD band RSRP and FDD band RSRP are compared.

[0085] In this step, in the case where at least one of TDD band RSRP and FDD band RSRP is not in the weak network signal range, the electronic device compares TDD band RSRP and FDD band RSRP.

[0086] Step 310: Communication is performed using the time division duplex frequency band or the frequency division duplex frequency band with higher RSRP.

[0087] In this step, the electronic device performs communication using the time division duplex frequency band or the frequency division duplex frequency band with higher RSRP.

[0088] Step 312: It is judged whether FDD band RSRP exceeds the sum of TDD band RSRP and a preset threshold.

[0089] In this step, if both the TDD band RSRP and the FDD band RSRP are in the weak network signal range, the FDD band RSRP and the sum of the TDD band RSRP and the preset threshold value are compared.

[0090] The electronic device determines whether the FDD band RSRP exceeds the sum of the TDD band RSRP and the preset threshold value.

[0091] If the FDD band RSRP does not exceed the sum of the TDD band RSRP and the preset threshold value, step 314 is continued.

[0092] If the FDD band RSRP exceeds the sum of the TDD band RSRP and the preset threshold value, step 326 is performed.

[0093] Step 314: Comparing the FDD band RSRP and the TDD band RSRP.

[0094] In this step, if the FDD band RSRP does not exceed the sum of the TDD band RSRP and the preset threshold value, the electronic device compares the FDD band RSRP and the TDD band RSRP.

[0095] Step 316: If the FDD band RSRP is less than the TDD band RSRP, using the time division duplex frequency band for communication.

[0096] In this step, if the FDD band RSRP is less than the TDD band RSRP, the electronic device uses the time division duplex frequency band with higher RSRP for communication.

[0097] Step 318: If the FDD band RSRP is equal to the TDD band RSRP, adding a compensation value to the TDD band RSRP.

[0098] In this step, if the FDD band RSRP is equal to the TDD band RSRP, the software in the electronic device adds a compensation value to the TDD band RSRP.

[0099] Step 320: Using the time division duplex frequency band with the added compensation value for communication.

[0100] In this step, the electronic device uses the time division duplex frequency band with the added compensation value for communication.

[0101] Step 322: If the FDD band RSRP is greater than the TDD band RSRP, adding a compensation value to the TDD band RSRP.

[0102] In this step, if the FDD band RSRP is greater than the TDD band RSRP, the software in the electronic device adds a compensation value to the TDD band RSRP.

[0103] Step 324: Communication is performed using the time division duplex frequency band after the compensation value is added.

[0104] In this step, the electronic device performs communication using the time division duplex frequency band after the compensation value is added.

[0105] Please refer to Figure 4 , Figure 4 A flowchart of a compensation method for a time division duplex frequency band is shown. Taking the weak network signal range of-100dBm to-120dBm as an example, the compensation method for the time division duplex frequency band can include the following steps:

[0106] Step 402: Monitoring the time division duplex frequency band and the frequency division duplex frequency band.

[0107] In this step, the electronic device monitors the time division signal of the time division duplex frequency band and the frequency division signal of the frequency division duplex frequency band.

[0108] Step 404: Obtaining TDD band RSRP and FDD band RSRP.

[0109] In this step, the electronic device obtains the TDD band RSRP of the time division signal and the FDD band RSRP of the frequency division signal.

[0110] Step 406: Determining that-100dBm≤TDD band RSRP≤-120dBm is satisfied, and-100dBm≤FDD band RSRP≤-120dBm is satisfied.

[0111] In this step, the TDD band RSRP and the FDD band RSRP are both within the range of-100dBm to-120dBm, and the electronic device determines that the TDD band RSRP satisfies-100dBm≤TDD band RSRP≤-120dBm, and the FDD band RSRP satisfies-100dBm≤FDD band RSRP≤-120dBm.

[0112] Step 408: Determining that 0≤FDD band RSRP-TDD band RSRP≤5 is satisfied.

[0113] In this step, the FDD band RSRP is greater than or equal to the TDD band RSRP, and the FDD band RSRP does not exceed the sum of the TDD band RSRP and a preset threshold value.

[0114] For example, when the preset threshold is 5, the electronic device determines that 0≤FDD band RSRP-TDD band RSRP≤5 is satisfied.

[0115] Step 410: The TDD band RSRP is compensated by 6 to obtain a compensated TDD band RSRP.

[0116] In this step, after determining that the above condition is satisfied, the software in the electronic device compensates the TDD band RSRP by 6 to obtain a compensated TDD band RSRP.

[0117] Step 412: Determine that 1≤compensated TDD band RSRP-FDD band RSRP≤6 is satisfied.

[0118] In this step, after compensating the TDD band RSRP by 6, it can be determined that 1≤compensated TDD band RSRP-FDD band RSRP≤6 is satisfied.

[0119] Step 414: Switch to the compensated time division duplex frequency band for communication.

[0120] In this step, the electronic device can switch to the compensated time division duplex frequency band for communication.

[0121] It can be understood that the preset threshold, compensation value and the like shown in the embodiments of the present application are only a preferred example, and other values can also be set according to the actual business scenario, as long as the electronic device can implement the method described in the embodiments of the present application.

[0122] Step 326: Use the frequency division duplex frequency band for communication.

[0123] In this step, if the FDD band RSRP exceeds the sum of the TDD band RSRP and the preset threshold, the electronic device uses the frequency division duplex frequency band with higher RSRP for communication.

[0139] The weak network determination module 602 is configured to determine that both the time division signal and the frequency division signal are in a weak network signal range.

[0140] The frequency band control module 604 is configured to use the time division duplex frequency band to communicate when the frequency division signal parameter does not exceed the sum of the time division signal parameter and a preset threshold value, and the preset threshold value is used to limit the difference range of the time division signal parameter and the frequency division signal parameter.

[0141] In one example, the time division signal parameter includes a reference signal received power of the time division duplex frequency band, and the frequency division signal parameter includes a reference signal received power of the frequency division duplex frequency band.

[0144] In one example, the frequency band control module 604 is further configured to use the frequency division duplex frequency band to communicate when the frequency division signal parameter exceeds the sum of the time division signal parameter and the preset threshold value when the time division signal parameter and the frequency division signal parameter are both in the signal range.

[0145] In one example, the frequency band control module 604 is further configured to compare the time division signal parameter and the frequency division signal parameter when at least one of the time division signal parameter and the frequency division signal parameter is not in the weak network signal range, use the time division duplex frequency band to communicate when the time division signal parameter is higher than the frequency division signal parameter, and use the frequency division duplex frequency band to communicate when the frequency division signal parameter is higher than the time division signal parameter.
