In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
Before introducing a radio frequency control method provided in an embodiment of the present application, an electronic device to which the radio frequency control method is applied is first introduced.
Referring to fig. 1, the rf circuit of the electronic device may include a baseband modem 11, an rf transceiver 12, a first rf path 13, a second rf path 14, and a third rf path 15. The first radio frequency path 13 may include a first amplifier 131, a first filter 132, a first switch 133, and a first antenna 134. The second radio frequency path 14 may include a second amplifier 141, a second filter 142, a second switch 143, and a second antenna 144. The third radio frequency path 15 may include a third amplifier 151, a third filter 152, a third switch 153, and a third antenna 154. The first rf path 13 and the third rf path 15 correspond to a second network frequency band (n41 or n78), the second rf path 14 corresponds to a first network frequency band (n3 or B3), and the first network frequency band is different from the second network frequency band.
Illustratively, the first radio frequency path 13 and the third radio frequency path 15 are High Band (HB) or Ultra-High Band (UHB) paths, the High Band may be N41, for example, and the Ultra-High Band may be N78, for example. The second radio frequency path 14 is a Low-Mid Band (LMB) path, and the LMB path may be, for example, a B3 frequency Band or an N3 frequency Band.
The electronic device may operate in a Non-dependent Networking (NSA) scenario or an SA (SA) independent networking scenario. For the independent networking SA, only 5G is needed to be connected with a base station independently; for the non-independent networking NSA, the implementation manner is a Long Term Evolution (LTE) and New air interface (NR) dual connection scenario, so as to ensure that LTE and NR can work simultaneously.
Specifically, the working process of the radio frequency circuit comprises the following steps: under the NSA non-independent networking scene, the second radio frequency path 14 transmits LTE radio frequency signals, and the first radio frequency path 13 or the third radio frequency path 15 transmits 5G NR radio frequency signals, that is, one of the first radio frequency path 13 and the third radio frequency path 15 and the second radio frequency path 14 operate simultaneously. In the SA independent networking scenario, the first rf path 13 and the third rf path 15 transmit the 5G NR rf signal simultaneously, that is, the electronic device is in a 2 × 2UL MIMO operating state.
Specifically, for radio frequency signals in a high frequency band or an ultra-high frequency band, the frequency is high, the transmission rate is higher, but the coverage performance is poor due to large path loss in the transmission process. For radio frequency signals in medium and low frequency bands, the frequency is lower, the transmission rate is lower, but the path loss is smaller in the transmission process, and the coverage performance is better. Based on this, under the condition that the coverage of the radio frequency signal in the high frequency band or the ultrahigh frequency band is poor, one of the first radio frequency path 13 and the third radio frequency path 15 may be controlled to transmit the 5G NR radio frequency signal in the high frequency band or the ultrahigh frequency band, and the second radio frequency path 14 may be controlled to transmit the 5G NR radio frequency signal in the medium and low frequency band, that is, the electronic device is in the NR UL CA operating state of LMB + UHB, so as to ensure the uplink coverage of the 5G NR radio frequency signal.
The radio frequency control method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Please refer to fig. 2, which is a flowchart illustrating a radio frequency control method according to an embodiment of the present application. The method can be applied to the electronic device of the foregoing embodiment, and the electronic device can be a mobile phone, a tablet computer, a notebook computer, and the like. The electronic equipment comprises a first radio frequency channel and a second radio frequency channel, wherein the first radio frequency channel corresponds to a first network frequency band, the second radio frequency channel corresponds to a second network frequency band, and the first network frequency band is different from the second network frequency band. As shown in fig. 2, the method may include steps 2100-2300, described in detail below.
The first radio frequency path is a High Band (HB) path or an Ultra-High Band (UHB) path, the High Band may be N41, for example, and the Ultra-High Band may be N78, for example. The second radio frequency path is a path of a Low-Mid Band (LMB), which may be, for example, a B3 frequency Band or an N3 frequency Band.
The Reference Signal Receiving Power (RSRP) may reflect the quality of the coverage performance of the rf Signal. The smaller the reference signal received power is, the worse the coverage performance of the radio frequency signal is, and the larger the reference signal received power is, the better the coverage performance of the radio frequency signal is.
The random access parameter is a parameter required when accessing the second radio frequency access, that is, how the second radio frequency access is configured can be known according to the random access parameter so as to access the second radio frequency access and normally work in the second radio frequency access. The random access parameters include mib (master Information block) Information and a plurality of SIB (system Information block) Information including, for example and without limitation, SIB1, SIB2, SIB4, SIB5, SIB6, SIB7, SIB8, SIB9, SIB10, SIB11, SIB12, and SIB 13. Wherein the MIB information and the plurality of SIB information mainly relate to: the method comprises the following steps of area tracking code information, cell ID position information (the position where the cell can be quickly locked and the position of a communication cell), network mode, available frequency band information (the specific frequency band of communication can be quickly locked), channel bandwidth information, system frame number information, frequency synchronization information, time synchronization information, access time information, physical hybrid automatic repeat request indication and other necessary information.
In this embodiment, the electronic device may measure the first reference signal received power on the first radio frequency path, and obtain a data frame from the NR radio frequency signal received by the first radio frequency path, and further demodulate the data frame to obtain a random access parameter related to the second radio frequency path.
In specific implementation, in an SA independent networking scenario, the electronic device is in a second operating state, that is, a 2 × 2UL MIMO operating state, that is, the radio frequency path corresponding to the second network frequency band simultaneously transmits the 5G NR radio frequency signal, and may also be understood as that the first radio frequency path and the third radio frequency path simultaneously transmit the 5G NR radio frequency signal. In the working process of the radio frequency circuit, the electronic device can obtain the reference signal receiving power of a first radio frequency path, wherein the first radio frequency path is any radio frequency path corresponding to a second network frequency band in the radio frequency circuit. And the electronic device acquires a data frame from the 5G NR radio frequency signal received by the first radio frequency channel, and further demodulates the data frame to acquire a random access parameter related to the second radio frequency channel.
After acquiring the first reference signal received power of the first radio frequency channel and demodulating the random access parameter of the second radio frequency channel from the radio frequency signal received by the first radio frequency channel, entering:
The first operating state is a state in which the first radio frequency path and the second radio frequency path simultaneously transmit NR radio frequency signals.
In this embodiment, it may be determined whether the electronic device needs to be switched to the first operating state according to the random access parameter according to the first reference signal received power of the first radio frequency path.
The first threshold may reflect whether coverage performance of the signal of the high frequency band or the ultra high frequency band is deteriorated. The first threshold may be set according to a test result, which is not limited in this embodiment of the application.
The first radio frequency path is a radio frequency path of one radio frequency circuit corresponding to the second network frequency band. The first reference signal received power in the first radio frequency path is smaller than the first threshold, which indicates that the coverage performance of the electronic device in the second network frequency band is poor.
Under the condition that the reference signal receiving power of the second radio frequency path is smaller than the first threshold, it is indicated that the coverage performance of the high-frequency band or ultrahigh-frequency band signal of the electronic device is poor, at this time, the first radio frequency path may be switched to the second radio frequency path, that is, one of the radio frequency paths corresponding to the second network frequency band is switched to the second radio frequency path, so that the electronic device is switched from the second working state to the first working state, and thus, the uplink coverage of the 5G NR radio frequency signal is ensured by using a good coverage signal of the medium and low frequency signals.
In this embodiment, the step 2200 of demodulating the random access parameter of the second rf path from the NR rf signal received by the first rf path may further include:
and in response to a set triggering event, demodulating the random access parameters of the second radio frequency path from the NR radio frequency signal received by the first radio frequency path.
In this embodiment, a set trigger event is set in the electronic device, and when the set trigger event is satisfied, the electronic device demodulates the random access parameter of the second radio frequency channel from the NR radio frequency signal received by the first radio frequency channel.
The set triggering event comprises at least one of the fact that the change value of the first reference signal received power of two adjacent time points reaches every set time and exceeds a second threshold value.
The above-mentioned set time intervals may be set according to the transmission time of the cell information, and the set time intervals may be 10 ms. That is, every 10ms, the electronic device demodulates and updates the random access parameter associated with the second rf path from the NR rf signal received by the first rf path, and stores the updated random access parameter associated with the second rf path in a register of the electronic device.
It can be understood that if the random access parameter associated with the second rf path is frequently demodulated and updated, a lot of resources are occupied, and in order to save resources, the update period can be extended, for example, to any value greater than or equal to 10 ms.
The two adjacent time points are two adjacent time points of the first radio frequency channel for transmitting the NR radio frequency signal. Since the NR radio frequency signal transmitted by the first radio frequency path is a high-frequency or ultra-high-frequency signal and is more sensitive to channel variation, the determination may be performed according to the first reference signal received power of the first radio frequency path, for example, when the variation value of the first reference signal received power of the first radio frequency path at two adjacent time points exceeds a second threshold, the random access parameter related to the second radio frequency path is demodulated and updated, and the updated random access parameter related to the second radio frequency path is stored in a register of the electronic device.
It is understood that, when the electronic device is controlled to switch to the first operating state according to the random access parameter in step 2200, that is, the first rf path and the second rf path are enabled to transmit the NR rf signal simultaneously, the step of demodulating the random access parameter related to the second rf path from the first rf path may be stopped. And when the electronic device is in the second working state, that is, when the two radio frequency paths corresponding to the first network frequency band simultaneously transmit the 5G NR radio frequency signals, the step of demodulating the random access parameter of the second radio frequency path from the NR radio frequency signal transmitted by the first radio frequency path is continuously executed.
According to the embodiment of the application, when the radio frequency signal is transmitted based on the first radio frequency channel, the random access parameter related to the second radio frequency channel is demodulated from the radio frequency signal received by the first radio frequency channel, and the electronic device is controlled to be switched to the first working state according to the random access parameter under the condition that the reference signal receiving power corresponding to the first radio frequency channel is smaller than the first threshold value, so that the first radio frequency channel corresponding to the first network frequency band and the radio frequency channel corresponding to the second network frequency band transmit the 5G NR radio frequency signal at the same time, the uplink coverage of the 5G NR radio frequency signal can be ensured by utilizing the good coverage performance of the medium and low frequency signal, and the continuously improved 5G uplink service can be met. Furthermore, the first radio frequency access is used for intercepting the random access parameters related to the second radio frequency access, and when the reference signal receiving power corresponding to the first radio frequency access is smaller than a first threshold value, one radio frequency access corresponding to the second network frequency band is quickly switched to the second radio frequency access by calling the random access parameters, so that the time delay is reduced, the reliability of communication is ensured, and the power consumption of the electronic equipment is reduced.
In an embodiment, after the step 2200 is executed to control the electronic device to switch to the first operating state according to the random access parameter, the radio frequency control method according to the embodiment of the present disclosure may further include the following steps 3100 to 3200:
3100, obtaining a second reference signal received power of the second rf path.
The second radio frequency path is a path of a Low-Mid Band (LMB), which may be, for example, a B3 frequency Band or an N3 frequency Band.
In this embodiment, after the electronic device is switched to the first operating state according to the random access parameter, the second reference signal receiving power of the second radio frequency path is obtained, which is related to continuously obtaining the second reference signal receiving power of the second radio frequency path in a process of simultaneously transmitting the 5G NR radio frequency signals based on the two radio frequency paths corresponding to the second network frequency band, so that the power consumption of the electronic device is reduced.
Step 3200, controlling the electronic device to continue to be in the first working state under the condition that the second reference signal received power is greater than a third threshold.
The third threshold may reflect whether the coverage performance of the medium and low frequency signals satisfies the path switching condition. The third threshold may be set according to the test result, which is not limited in this embodiment of the application.
When the second reference signal received power in the second radio frequency path is greater than the third threshold, it indicates that the coverage performance of the electronic device in the second network frequency band is better, and at this time, the electronic device can stably operate in the first operating state.
It can be understood that, in the case that the second reference signal received power of the second rf path is less than or equal to the third threshold, it indicates that the quality of the network signal in the medium-low frequency band is not good, at this time, the electronic device may switch to the 4G network, or return to the second operating state, that is, control the two rf paths of the high frequency or the ultra-high frequency to continue to transmit the NR rf signal, at this time, the coverage performance of the high frequency or the ultra-high frequency is poor.
According to the embodiment, after the electronic device is controlled to be switched to the first working state, that is, after the first radio frequency path and the second radio frequency path are controlled to simultaneously transmit the NR radio frequency signal, the second reference signal receiving power of the second radio frequency path is obtained, so that the power consumption of the electronic device is reduced.
In some embodiments of the present application, the electronic device further includes a third rf path, where the third rf path corresponds to the first network frequency band, that is, the third rf path and the first rf path correspond to the same network frequency band. Illustratively, the third radio frequency path is a High Band (HB) path, which may be, for example, N41, or an Ultra-High Band (UHB) path, which may be, for example, N78.
In this embodiment, before performing step 2200 above to control the electronic device to switch to the first operating state according to the random access parameter, the radio frequency control method according to the embodiment of the present disclosure may further include steps 4100 to 4200 as follows.
Step 4100, when the electronic device is in the third working state, acquiring a first reference signal received power of the first radio frequency path or a third reference signal received power of the third radio frequency path.
The third working state is a state that the second radio frequency path transmits an LTE radio frequency signal, and the first radio frequency path or the third radio frequency path transmits an NR radio frequency signal. The third operating state may be, for example, an EN DC double connected state.
The reference signal received power may reflect the quality of the coverage performance of the radio frequency signal. The smaller the reference signal received power is, the worse the coverage performance of the radio frequency signal is, and the larger the reference signal received power is, the better the coverage performance of the radio frequency signal is. Based on this, according to the reference signal received power of the first radio frequency path or the third radio frequency path, whether the super uplink switching condition is satisfied can be judged, and whether the electronic device is controlled to be switched from the third working state to the second working state can be further determined.
Step 4200, when the first reference signal received power of the first radio frequency path or the third reference signal received power of the third radio frequency path is greater than the fourth threshold and the electronic device starts the target application, controlling the electronic device to switch to the second operating state.
The second operating state is a state in which the second rf path and the third rf path transmit NR rf signals simultaneously. That is, the second operating state is a state in which two radio frequency paths corresponding to the first network frequency band simultaneously transmit the NR radio frequency signal, and the second operating state may be, for example, a 2 × 2UL MIMO operating state.
The fourth threshold is used for evaluating whether the electronic device has a higher uplink demand in the first network frequency band. The fourth threshold may be set according to a test result, which is not limited in this embodiment of the application.
The target application is an application with high uplink rate requirements.
The target application is an upper layer application playing high definition video. The target application is also, for example, an upper layer application that uploads a large number of photos.
In specific implementation, when the first reference signal received power of the first radio frequency path or the third reference signal received power of the third radio frequency path is greater than the fourth threshold and the electronic device starts an application with a high uplink rate, it indicates that the electronic device has a high uplink demand in the first network frequency band and the electronic device has the high uplink rate demand, and at this time, the super uplink switching condition is satisfied, and the electronic device is controlled to switch from the third operating state to the second operating state.
In this embodiment, whether to control the electronic device to switch to the second working state is determined according to the first reference signal received power of the first radio frequency channel or the third reference signal received power of the third radio frequency channel and the started target application, so that the accuracy of the determination can be improved, the working state of the electronic device can be adjusted in time, and the requirement of a user on the uplink performance of the 5G NR radio frequency signal is met.
