Specifically, the 4G network and the 5G network work at the same time. The 4G network is responsible for registration and connection with the base station, and the 5G network is responsible for data transmission.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0022] The radio frequency control method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.
[0023] Please see Figure 1, which is a flow chart of a radio frequency control method provided in an embodiment of the present application. The method can be applied to an electronic device, and the electronic device can be a mobile phone, a tablet computer, a laptop computer, etc. The electronic device includes a first radio frequency path and a second radio frequency path, the first radio frequency path corresponds to a first frequency band, the second radio frequency path corresponds to a second frequency band, and the first frequency band is different from the second frequency band. Exemplarily, the first radio frequency path can be a path of a low-mid frequency band (Low-Mid Band, LMB) of a 4G network, and the low-mid frequency band can be, for example, a B3 frequency band. The second radio frequency path can be a path of a high-frequency band (HighBand, HB) or an ultra-high-frequency band (Ultra-high Band, UHB) of a 5G network, and the high-frequency band can be, for example, N41, and the ultra-high frequency band can be, for example, N78.
[0024] The electronic device can work in NSA (Non-Standalone, NSA) scenarios, and can also work in SA (Standalone, SA) scenarios. For SA, it only needs 5G to connect to the base station alone; for NSA, it is implemented in a dual-connection scenario of Long Term Evolution (LTE) and New Radio (NR) to ensure that LTE and NR can work at the same time.
[0025] Specifically, the working process of the RF circuit includes: in the NSA non-independent networking scenario, the first RF path transmits LTE RF signals, and the second RF path transmits 5G NR RF signals, that is, the first RF path and the second RF path work simultaneously. In the SA independent networking scenario, the second RF path transmits 5G NR RF signals, that is, only the second RF path transmits 5GNR RF signals.
[0026] like Figure 1 As shown, the method may include steps 1100 to 1300, which are described in detail below.
[0027] Step 1100: When the first radio frequency path and the second radio frequency path are working simultaneously, obtain parameter information of the first radio frequency path and parameter information of the second radio frequency path.
[0028] When the first RF path and the second RF path work simultaneously, the first RF path transmits an LTE RF signal and the second RF path transmits a 5G NR RF signal. At this time, the electronic device works in an NSA non-independent networking scenario.
[0029] The parameter information of the first RF path includes the first transmission frequency of the first RF path, the channel and bandwidth corresponding to the first transmission frequency, and the parameter information of the second RF path includes the second transmission frequency of the second RF path, the channel and bandwidth corresponding to the second transmission frequency.
[0030] Exemplarily, the first RF path corresponds to the B3 frequency band, and the second RF path corresponds to the N78 frequency band. When the electronic device works in the NSA non-independent networking scenario, the first RF path transmits the LTE RF signal in the B3 frequency band. The harmonic signal corresponding to the LTE RF signal in the B3 frequency band may fall into the channel of the N78 frequency band, thereby causing the sensitivity of the N78 frequency band to decrease, seriously affecting the receiving performance of the N78 frequency band.
[0031] Correspondingly, when the first RF path corresponds to the B3 frequency band, the first transmission frequency of the first RF path may be 1755 MHz, the channel corresponding to the first transmission frequency may be the LTE B3 CH19650 channel, and the bandwidth corresponding to the first transmission frequency is 1750 MHz-1760 MHz.
[0032] Correspondingly, when the second RF path corresponds to the N78 frequency band, the second transmission frequency of the second RF path is 3550 MHz, the channel corresponding to the second transmission frequency can be the NR n78 CH636666 channel, and the bandwidth corresponding to the second transmission frequency is 3500 MHz-3600 MHz.
[0033] In the case where the first radio frequency path and the second radio frequency path work simultaneously, after obtaining the parameter information of the first radio frequency path and the parameter information of the second radio frequency path, enter:
[0034] In the case where the first radio frequency path and the second radio frequency path work simultaneously, after obtaining the parameter information of the first radio frequency path and the parameter information of the second radio frequency path, enter:
[0035] Step 1200: When a harmonic signal in a radio frequency signal transmitted based on the first transmission frequency is located in a channel corresponding to the second transmission frequency, a first adjustment request is sent to a base station so that the base station increases a bandwidth corresponding to the second transmission frequency.
[0036] Continuing with the above example, when the first RF path corresponds to the B3 frequency band, the second RF path corresponds to the N78 frequency band, and the electronic device operates in the NSA non-independent networking scenario, the first RF path transmits the LTE RF signal of the B3 frequency band. The harmonic signal corresponding to the RF signal of the B3 frequency band may fall into the channel of the N78 frequency band, thereby causing the sensitivity of the N78 frequency band to decrease, seriously affecting the receiving performance of the N78 frequency band.
[0037] In this embodiment, when the harmonic signal in the radio frequency signal transmitted based on the first transmission frequency is located in the channel corresponding to the second transmission frequency in step 1200, before sending a first adjustment request to the base station for the base station to increase the bandwidth corresponding to the second transmission frequency, the frequency of the harmonic signal may be calculated based on the first transmission frequency. For example, it is calculated whether the second harmonic signal is located in the channel corresponding to the second transmission frequency, whether the third harmonic signal is located in the channel corresponding to the second transmission frequency, etc.
[0038] Exemplarily, the first RF path corresponds to the B3 frequency band, and the second RF path corresponds to the N78 frequency band. The frequency of the harmonic signal may be calculated based on the first transmission frequency 1755 MHz. For example, the frequency of the LTE harmonic signal may be 3500 MHz-3510 MHz.
[0039] In one embodiment, in this step 1300, when the harmonic signal in the radio frequency signal transmitted based on the first transmission frequency is located in the channel corresponding to the second transmission frequency, sending a first adjustment request to the base station for the base station to increase the bandwidth corresponding to the second transmission frequency may further include: when the harmonic signal in the radio frequency signal transmitted based on the first transmission frequency is located in the downlink service channel corresponding to the second transmission frequency, sending a first adjustment request to the base station for the base station to increase the bandwidth allocated to the second transmission frequency.
[0040] In this example, when the harmonic signal in the radio frequency signal transmitted based on the first transmission frequency is located in the channel corresponding to the second transmission frequency, it will further determine whether the harmonic signal is located in the downlink control channel (Physical Downlink Control Channel, PDCCH) of the second transmission frequency. When the harmonic signal is not located in the downlink control channel of the second transmission frequency, the harmonic signal is located in the downlink service channel (Physical Downlink Shared Channel, PDSCH) of the second transmission frequency. At this time, a first adjustment request is sent to the base station so that the base station can increase the bandwidth corresponding to the second transmission frequency.
[0041] In this example, the channels corresponding to the second transmission frequency include a downlink control channel and a downlink service channel. It can be understood that if it is not located in the downlink control channel corresponding to the second transmission frequency, it is located in the downlink service channel corresponding to the second transmission frequency.
[0042] The uplink and downlink control channel PDCCH contains CRC check / uplink and downlink resource scheduling, as well as other modulation methods, HARQ retransmission information, SRS request and other information. Its main function is to transmit downlink control information and UL Grant to facilitate the terminal device to correctly receive PDSCH.
[0043] The above downlink service channel PDSCH is used to transmit downlink user data. As the service channel for 5G data transmission, the downlink data transmitted by the terminal device is all carried out on PDSCH.
[0044] In this example, the LTE harmonic signal falls within the bandwidth of the NR band (for example, the B3 band interferes with the N78 band). At this time, the LTE harmonic signal can be described as the in-band noise signal of NR. When calculating the signal-to-noise ratio (SNR) within the NR band, the noise power within the entire NR bandwidth is calculated. Since the noise power is a fixed value, if the NR bandwidth is increased at this time, the noise power will be spread over the entire band, thereby reducing the signal-to-noise ratio (SNR) per unit bandwidth, thereby improving the interference of harmonics to NR received signals under large bandwidth. Actual test results also prove that increasing the NR bandwidth can improve the interference of LTE harmonics on the sensitivity of the NR band, namely ENDC interference.
[0045] According to the method of this embodiment, when the first RF path and the second RF path of the electronic device work simultaneously, that is, the electronic device works in the NSA scenario, parameter information of the first RF path and the second RF path are respectively obtained, and when the harmonic signal in the RF signal transmitted based on the first transmission frequency is located in the channel corresponding to the second transmission frequency, a first adjustment request is sent to the base station for the base station to increase the bandwidth corresponding to the second transmission frequency, thereby improving the interference of the harmonic signal to the NR reception signal under a large bandwidth and improving the reception performance of NR.
[0046] In one embodiment, after executing the above step 1200 and obtaining parameter information of the first RF path and parameter information of the second RF path when the first RF path and the second RF path are working simultaneously, the RF control method of the embodiment of the present disclosure may further include: when a harmonic signal in the RF signal transmitted based on the first transmission frequency is located in a downlink control channel corresponding to the second transmission frequency, sending a second adjustment request to the base station for the base station to change the position of the downlink control channel.
[0047] In this embodiment, when the harmonic signal in the radio frequency signal transmitted based on the first transmission frequency is located in the channel corresponding to the second transmission frequency, it will further determine whether the harmonic signal is located in the downlink control channel corresponding to the second transmission frequency. When the harmonic signal is located in the downlink control channel corresponding to the second transmission frequency, a second adjustment request is sent to the base station so that the base station can change the position of the downlink control channel.
[0048] On the one hand, PDCCH contains the CRC check signal required for downlink demodulation. If the CRC check signal is interfered with, the CRC check signal cannot be demodulated. If the CRC check is incorrect, the terminal device will think that the control channel has either generated an unrecoverable error during transmission, or that the control channel is sent to other electronic devices, so that the PDCCH information will be ignored by the terminal device. If the PDCCH is ignored, the terminal device will not be able to demodulate the content of the subsequent PDSCH. On the other hand, the PDCCH in NR also contains uplink scheduling information and downlink scheduling information, so that the terminal device can correctly receive the PDSCH and allocate uplink resources for the PDSCH. If the uplink scheduling information and downlink scheduling information are interfered with, the terminal device will not be able to demodulate the PDSCH information at the correct time, resulting in demodulation failure.
[0049] From the above, we can know that if the LTE harmonic signal happens to fall into the PDCCH of NR, it will affect the CRC check, uplink scheduling information and downlink scheduling information, resulting in the inability to demodulate the data information in the PDSCH, resulting in a decrease in the throughput of the terminal device and affecting the actual user experience.
[0050] Specifically, the changing of the position of the downlink control channel includes: the changing of the position of the downlink control channel includes: changing a first position of the downlink control channel in the bandwidth corresponding to the second transmission frequency to a second position in the bandwidth corresponding to the second transmission frequency.
[0051] The first position in the bandwidth corresponding to the second transmission frequency may be a CORESET set, that is, the PDCCH position is located on the CORESET set by default.
[0052] The second position in the bandwidth corresponding to the second transmission frequency may be a position other than the CORESET set.
[0053] When the LTE harmonic signal falls within the PDCCH, since the PDCCH carries CRC information and uplink and downlink scheduling information, interference may easily cause a significant impact on throughput. Therefore, the terminal device requests the base station to change the PDCCH position to other positions in the bandwidth corresponding to the second transmission frequency to avoid LTE harmonic interference to the PDCCH channel corresponding to the second transmission frequency, thereby reducing the impact on throughput.
[0054] Continuing with the above example, since the transmission frequency of the LTE harmonic signal is 3500MHz-3510MHz, the channel corresponding to the second transmission frequency n78 can be the NR n78 CH636666 channel, and the bandwidth corresponding to the second transmission frequency n78 is 3500MHz-3600MHz, the default PDCCH position is between 0-24RB, and the actual frequency band position occupied by the PDCCH is 3500MHz-3508.64MHz (each RB is 360KHz, and 24RB occupies a total of 8.64MHz bandwidth). The frequency of the LTE harmonic signal of 3500-3510MHz is just within the 3500-3508.64MHz bandwidth occupied by the n78 PDCCH, then a second adjustment request can be sent to the base station so that the base station changes the first position of the PDCCH in the bandwidth corresponding to the second transmission frequency to the second position of the bandwidth corresponding to the second transmission frequency.
[0055] In this embodiment, the harmonic interference in the NSA combination scenario is improved by changing the position of the downlink control channel, thereby improving the impact of LTE harmonics on NR reception performance without changing the hardware.
[0056] In one embodiment, after executing the above step 1200 in which the first adjustment request is sent to the base station so that the base station increases the bandwidth corresponding to the second transmission frequency, the radio frequency control method of the present disclosure may further include:
[0057] Step 2100: Obtain a first signal-to-noise ratio of the second radio frequency path.
[0058] The first signal-to-noise ratio SNR1 of the second radio frequency path is the signal-to-noise ratio of the second radio frequency path after the bandwidth corresponding to the second transmission frequency is increased or after the position of the downlink control channel is changed.
[0059] Step 2200: When the first signal-to-noise ratio is less than or equal to the second signal-to-noise ratio, continue to detect whether the harmonic signal in the radio frequency signal transmitted by the first transmitting frequency is located in the channel corresponding to the second transmitting frequency.
[0060] The second signal-to-noise ratio SNR2 of the second radio frequency path is the signal-to-noise ratio corresponding to the second radio frequency path before the bandwidth corresponding to the second transmitting frequency is increased or before the position of the downlink control channel is changed.
[0061] In this embodiment, when the first signal-to-noise ratio is less than or equal to the second signal-to-noise ratio, it indicates that the signal interference problem of the second RF path has not been improved. Here, it is necessary to re-execute the above step 1200 to continue to detect whether the harmonic signal in the RF signal transmitted by the first transmitting frequency is located in the channel corresponding to the second transmitting frequency.
[0062] Step 2300: When the first signal-to-noise ratio is greater than the second signal-to-noise ratio, save the first signal-to-noise ratio.
[0063] In this embodiment, when the first signal-to-noise ratio is less than the second signal-to-noise ratio, the first signal-to-noise ratio is saved, the terminal device records the improvement of the signal-to-noise ratio SNR of the second RF path, and uses it as a basis for the next improvement and as a reference for the next improvement, and the terminal device enters the normal communication mode.
[0064] The following is a specific example to illustrate the process of the radio frequency control method. In this example, the electronic device works in the NSA scenario. Figure 2 , the radio frequency control method includes steps 201 to 210.
[0065] Step 201, the electronic device is turned on and controlled to be in the NSA working state.
[0066] Step 202: Obtain a first transmission frequency of a first radio frequency path, a channel and a bandwidth corresponding to the first transmission frequency, and a second transmission frequency of a second radio frequency path, a channel and a bandwidth corresponding to the second transmission frequency.
[0067] Step 203, determining whether the harmonic signal in the radio frequency signal transmitted based on the first transmitting frequency is located in the channel corresponding to the second transmitting frequency, if yes, executing step 204, otherwise executing step 210.
[0068] Step 204, when the harmonic signal in the RF signal transmitted based on the first transmission frequency is located in the channel corresponding to the second transmission frequency, further determine whether the harmonic signal is located on the downlink control channel PDCCH corresponding to the second transmission frequency; if so, execute step 205; otherwise, execute step 206.
[0069] Step 205. When the harmonic signal is located on the PDCCH corresponding to the second transmission frequency, since the PDCCH carries CRC information and uplink and downlink scheduling information, it is easy to cause a large throughput impact if interfered with. At this time, the electronic device requests the base station to change the NR PDCCH position to other positions of the NR bandwidth to avoid LTE harmonic interference to the NR PDCCH channel, thereby reducing the impact on throughput and entering step 207.
[0070] Step 206, when the harmonic signal is not located on the PDCCH corresponding to the second transmission frequency, it indicates that it is a normal situation of LTE harmonic interference NR. At this time, the base station is requested to increase the bandwidth corresponding to the second transmission frequency, improve the interference level, and enter step 208.
[0071] In step 207, the base station agrees to the request to change the NR PDCCH position. At this time, the electronic device and the base station simultaneously change the PDCCH position to the high channel corresponding to the second transmission frequency to avoid LTE harmonics falling on the NR PDCCH, and enter step 208.
[0072] Step 208, compare the current signal-to-noise ratio of the second RF path with the initial signal-to-noise ratio. If the current signal-to-noise ratio is greater than the initial signal-to-noise ratio, indicating that the interference of the second RF path has improved, then execute step 209; otherwise, execute step 210.
[0073] Step 209, when the first signal-to-noise ratio is greater than the initial signal-to-noise ratio, the first signal-to-noise ratio is saved and the process proceeds to step 210. When the first signal-to-noise ratio is less than or equal to the initial signal-to-noise ratio, it indicates that there is no improvement, and step 203 is repeated.
[0074] Step 210: The electronic device communicates normally.
[0075] In this example, the harmonic interference in the NSA combination scenario is improved by changing the position of the downlink control channel and using NR signals of different bandwidths, thereby improving the impact of LTE harmonics on NR reception performance without changing the hardware.
