As shown in fig. 2, in one embodiment, a method for testing a receiving link is provided, which may be applied to an electronic device, which may include, but is not limited to, the terminal device 110 described above. The method for testing the receiving link can comprise the following steps:
The electronic device may include a radio frequency module, which may include one or more transmit modules and one or more receive modules, and optionally, each transmit module may include a Power Amplifier (PA) and a transmit antenna, and each receive module may include a receive unit and a receive antenna, where the PA and the receive unit may both be connected to the radio transceiver. Optionally, the power amplifier may be configured to amplify the transmission signal, send the amplified transmission signal to the transmission antenna, and transmit the amplified transmission signal by the transmission antenna. The electronic equipment can send the transmission signal to the power amplifier through the radio frequency transceiver, and the power amplifier can amplify the transmission signal to obtain enough power current, so that the transmission signal can be converted into electromagnetic waves through the transmitting antenna to be radiated. The receiving unit may be configured to process (e.g., filter) a received signal received by the receiving antenna and transmit the processed received signal to the radio frequency transceiver. The transmitting antenna and the receiving antenna may be the same antenna, that is, share the same antenna for transmitting and receiving signals, and the switching device switches between transmitting and receiving signals of the antennas, and the transmitting antenna and the receiving antenna may also be different antennas, which is not limited herein.
In some embodiments, the electronic device may be a device supporting 4G (4th generation mobile communication technology) communication, or may also be a device supporting 5G (5th generation mobile communication technology) communication, and in the 5G communication, there are two major deployment schemes of NSA (non-standby networking) and SA (standby networking), where the NSA deployment scheme refers to modification on a 4G base station to implement transmission of 5G signals. Under NSA, in order to improve the data transmission rate and ensure the stability of signal transmission, the electronic device may adopt dual connectivity technology such as endec (E-UTRAN, new radio dual connectivity), where endec is a 4G and 5G dual connectivity, and the electronic device is connected to a 4G base station and a 5G base station simultaneously and supports the transmission of 4G signals and 5G signals. Under ENDC, different combinations of frequency bands may be employed to support transmission and/or reception of signals belonging to multiple different frequency bands.
In the embodiment of the present application, the transmitting frequency band corresponding to the transmitting module and the receiving module corresponding to the receiving module selected by the electronic device may be different frequency bands, that is, the uplink frequency and the downlink frequency of the radio frequency module in the electronic device may respectively correspond to different frequency bands. For example, the electronic device may be an apparatus supporting the endec, and for a frequency band combination adopted under the endec, the transmitting module may support a first frequency band in the frequency band combination, and the receiving module may support a second frequency band in the frequency band combination. Optionally, the transmitting frequency band corresponding to the transmitting module may be an LTE frequency band in the frequency band combination, and the receiving frequency band corresponding to the receiving module may be an NR frequency band in the frequency band combination, or the transmitting frequency band corresponding to the transmitting module may be an NR frequency band in the frequency band combination, and the receiving frequency band corresponding to the receiving module may be an LTE frequency band in the frequency band combination. For example, a B3/N8 frequency band combination is adopted under ENDC, wherein the transmitting frequency of B3 is 1710-1785 MHz (megahertz), the receiving frequency is 1805-1880 MHz, the transmitting frequency of N8 is 880-915 MHz, the receiving frequency is 925-960 MHz, N8 can be used as the transmitting frequency band, and B3 is used as the receiving frequency band.
In some embodiments, the receiving Frequency band corresponding to the receiving module may be an FDD (Frequency Division duplex) Frequency band, a receiving Frequency range of the FDD Frequency band is different from a transmitting Frequency range, the transmitting Frequency band corresponding to the transmitting module may be a TDD (Time Division duplex) Frequency band or an FDD Frequency band, and the receiving Frequency range of the TDD Frequency band is the same as the transmitting Frequency range.
In this embodiment, in order to solve the problem that the self-test of the receiving link cannot be performed due to the difference between the transmitting frequency band and the receiving frequency band (i.e., the difference between the transmitting frequency range and the receiving frequency range), the electronic device may control at least one transmitting module to transmit a transmitting signal, and a harmonic or an intermodulation of the transmitting signal may generate a receiving signal with a frequency in the receiving frequency band, where the harmonic may refer to a signal with a frequency that is an integral multiple of the frequency of the transmitting signal, and the intermodulation refers to a modulation signal generated by an interaction between a plurality of transmitting signals. That is, the in-band signal in the receiving frequency band can be generated through the harmonic wave or intermodulation of the transmitting signal to complete the generation of the information source, so that the receiving module can receive the receiving signal in the receiving frequency band to realize the performance self-test of the receiving link without additionally using a test device.
The electronic device can determine the signal intensity corresponding to the received signal received by the receiving module, and judge whether the receiving module is in a normal receiving state according to the signal intensity so as to determine the test result corresponding to the receiving module. In some embodiments, the signal strength corresponding to the received signal may be compared to a strength threshold, which may be based on actual requirements of the device. If the signal strength of the received signal is greater than or equal to the strength threshold, which indicates that the receiving module can normally receive the signal in the receiving frequency band, it may be determined that the test result corresponding to the receiving module is that the receiving module is in a normal receiving state and the performance of the receiving link is normal. If the signal strength of the received signal is smaller than the strength threshold, it is indicated that the receiving module cannot normally receive the signal in the receiving frequency band, and the performance of the receiving link is affected, and it is determined that the test result corresponding to the receiving module is that the receiving module is not in a normal receiving state.
Illustratively, fig. 3 is an architecture diagram of a radio frequency module in one embodiment. As shown in fig. 3, the rf module of the electronic device may include a plurality of transmitting modules and a plurality of receiving modules, the transmitting modules and the receiving modules supporting the same frequency band (e.g., the transmitting modules and the receiving modules supporting the B3 frequency band, or the transmitting modules and the receiving modules supporting the B8 frequency band, etc.) may share the same transceiver antenna and the same rf front end, different transmitting modules may support transmitting signals of the same or different frequency bands, and different receiving modules may support receiving signals of the same or different frequency bands. As a specific implementation manner, a receiving frequency band corresponding to a receiving module to be tested may be determined, a target transmitting module capable of generating an in-band signal in the receiving frequency band through harmonic or intermodulation may be selected from a plurality of transmitting modules, and a transmitting signal may be sent to a power amplifier in each determined target transmitting module through a radio frequency transceiver to control each target transmitting module to transmit the transmitting signal. The receiving channels can be controlled by the receiving modules to be tested to open through the radio frequency transceiver, and receiving signals with the frequency in the receiving frequency band generated by harmonic waves or intermodulation of the transmitting signals are received. The signal strength of the received signal received by each receiving module to be tested can be respectively compared with the strength threshold value, and whether each receiving module to be tested is in a normal receiving state or not is judged so as to determine the test result corresponding to each receiving module to be tested.
It should be noted that, the receiving module to be tested that receives the received signal and the target transmitting module that transmits the transmitted signal may share the same transceiver antenna and the same rf front end (for example, the power amplifier 1 in fig. 3 may transmit the transmitted signal, and the receiving unit 1 receives the received signal), or may not share the same transceiver antenna and the same rf front end (for example, the power amplifier 2 in fig. 3 may transmit the transmitted signal, and the receiving unit 1 receives the received signal), and it is not limited herein that it is mainly enough to ensure that the signal generated by the harmonic wave or intermodulation of the transmitted signal is within the receiving frequency band of the receiving module.
It should be noted that the method for testing a receiving link provided in the embodiment of the present application is not only applied to a scenario where a transmitting frequency band and a receiving frequency band in a frequency band combination such as an FDD frequency band or an endec frequency band are not consistent, but also applied to a scenario where a transmitting frequency band and a receiving frequency band in other frequency bands or frequency band combinations are not consistent.
In the embodiment of the application, at least one transmitting module is controlled to transmit a transmitting signal, a receiving module is used for receiving a receiving signal corresponding to the transmitting signal, the receiving signal is generated by harmonic waves or intermodulation of the transmitting signal, a test result corresponding to the receiving module is determined according to the signal strength corresponding to the receiving signal, the test result is used for indicating whether the receiving module is in a normal receiving state, the harmonic waves or the intermodulation of the transmitting signal are used for generating the receiving signal with the frequency in the receiving frequency band of the receiving module, the self-test of the receiving link by the transmitting module is realized, the receiving state of the receiving module can be reliably and effectively tested, the performance test of the receiving link is realized, additional complex test equipment does not need to be additionally deployed, the test cost is reduced, and the test flexibility is improved.

The electronic equipment can only select to transmit a transmitting signal of one frequency, can determine a receiving frequency band corresponding to a receiving module to be tested, and selects a frequency of which the corresponding harmonic frequency is in the receiving frequency band from the transmitting frequency band corresponding to the transmitting module as a first frequency, wherein the harmonic frequency of the first frequency is an integer multiple of the first frequency. The transmitting module can send a transmitting signal of a first frequency to a power amplifier of the transmitting module through a radio frequency transceiver, and the transmitting signal is amplified by the power amplifier and then transmitted through an antenna. The receiving module to be tested can be controlled by the radio frequency transceiver to open the receiving channel and receive the receiving signal generated by the harmonic wave of the transmitting signal of the first frequency, wherein the receiving signal is the harmonic wave signal generated by the transmitting signal of the first frequency.
For example, if the receiving frequency band corresponding to the receiving module is 1805-1880 MHz of the B3 frequency band, and the transmitting frequency band corresponding to the transmitting module is 880-915 MHz of the B8 frequency band, the first frequency may be set to 910MHz, and the second harmonic of 910MHz is 1820MHz, and the first frequency is in the receiving frequency band, so that the receiving module receives the receiving signal when the receiving link is normal, and the self-test of the receiving link is completed.
In the embodiment of the application, the transmitting module is controlled to transmit the transmitting signal of which the corresponding harmonic frequency is in the first frequency band of the receiving frequency band, so that the receiving module can receive the receiving signal under the condition that the receiving link is normal, the self-test of the receiving link by the transmitting module is realized, the reliability of the test is ensured, no additional test equipment is required to be deployed, the test cost is reduced, and the flexibility of the test is improved.
