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 the method for adjusting an uplink power level provided in the embodiments of the present application, an electronic device to which the method for adjusting an uplink power level 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 corresponds to a first network frequency band, the second rf path 14 and the third rf path 15 correspond to a second network frequency band, and the first network frequency band is different from the second network frequency band.
Illustratively, the first radio frequency path 13 is a path of a Low-Mid Band (LMB), which may be, for example, a B3 frequency Band or an N3 frequency Band. The second rf path 14 and the third rf 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 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: in the NSA non-independent networking scenario, the first radio frequency path 13 transmits an LTE radio frequency signal, and the second radio frequency path 14 or the third radio frequency path 15 transmits a 5G NR radio frequency signal, that is, one of the second radio frequency path 14 and the third radio frequency path 15 and the first radio frequency path 13 operate simultaneously. In the SA independent networking scenario, the second rf path 14 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.
In some embodiments, the electronic device may be a terminal device supporting 5G NG UL CA (Carrier Aggregation) technology. The CA technology can aggregate the frequency spectrum resources of the same frequency band or different frequency bands for the terminal to use, thereby improving the utilization rate of the resources of the whole network.
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 second radio frequency path 14 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 first radio frequency path 113 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 electronic device may be a terminal device supporting 5G NG SUL (supplemental Uplink) technology. The SUL technique ensures uplink coverage by providing a supplemental uplink (typically in the low band).
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 the radio frequency signals of the 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 signals in the high frequency band or the ultrahigh frequency band is poor, any one of the second radio frequency path 14 and the third radio frequency path 15 may be controlled to transmit the 5G NR radio frequency signals in the high frequency band or the ultrahigh frequency band, and the first radio frequency path 113 is controlled to transmit the 5G NR radio frequency signals in the medium and low frequency band, that is, the electronic device is in the NR SUL operating state of LMB + UHB, so as to ensure the uplink coverage of the 5G NR radio frequency signals.
The method for adjusting the uplink power level according to 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 method for adjusting uplink power level 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.
In step 2100, the electronic device is controlled to switch to a first operating state when the reference signal received power corresponding to the second rf path is smaller than a first threshold and the reference signal received power of the first rf path is greater than a second threshold.
Wherein the first operating state is a state in which the first radio frequency path and the second radio frequency path simultaneously transmit an NR radio frequency signal.
The first 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 second 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.
For radio frequency signals in a high frequency band or an ultrahigh frequency band, the frequency is high, the transmission rate is higher, but the coverage performance is poorer due to larger path loss in the transmission process. For the radio frequency signals of the 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, the electronic device can be controlled to switch to the first working state according to the path quality of the radio frequency paths of different network frequency bands so as to include uplink coverage of the G NR radio frequency signal.
In this embodiment, whether to switch the electronic device to the first operating state may be determined according to the reference signal received power of the radio frequency path.
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 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 second radio frequency path is a radio frequency path of one of the radio frequency circuits corresponding to the second network frequency band. The reference signal received power in the second 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.
The second threshold may reflect whether the coverage performance of the medium and low frequency signals meets the path switching condition. The second threshold may be set according to a test result, which is not limited in this embodiment of the application.
The reference signal received power in the first radio frequency path is greater than the second threshold, which indicates that the coverage performance of the electronic device in the first network frequency band is better.
Based on the above, according to the reference signal receiving powers of different radio frequency paths, the quality of the coverage performance of the signals of different frequency bands can be determined, and further, whether to control the electronic device to switch to the first working state or not can be determined, so that the uplink coverage of the 5G NR radio frequency signal is ensured by utilizing the good coverage of the medium and low frequency signals.
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, a radio frequency path corresponding to a second network frequency band simultaneously transmits a 5G NR radio frequency signal. In the working process of the radio frequency circuit, acquiring reference signal receiving power of a first radio frequency channel and reference signal receiving power of a second radio frequency channel, wherein the second radio frequency channel is any radio frequency channel corresponding to a second network frequency band in the radio frequency circuit, and under the condition that the reference signal receiving power of the second radio frequency channel is smaller than a first threshold and the reference signal receiving power of the first radio frequency channel is larger than a second threshold, the coverage performance of a high-frequency band or ultrahigh-frequency band signal of the electronic equipment is poor, the coverage performance of a medium-low frequency signal is good, and a channel switching condition is met, at the moment, the second radio frequency channel can be switched to the first radio frequency channel, namely one radio frequency channel corresponding to the second network frequency band is switched to the first radio frequency channel, so that the electronic equipment is switched from a second working state to a first working state, and good coverage signals of the medium-low frequency signal are utilized, and ensuring the uplink coverage of the 5G NR radio frequency signal.
After step 2100, step 2200 is executed to obtain a transmission power margin of the first rf path when the electronic device is in the first operating state.
In this embodiment, the Power Headroom (PH) may reflect the quality of the medium and low frequency signals transmitted by the first rf path, that is, the quality of the coverage of the medium and low frequency signals. Specifically, the larger the transmission power margin of the first radio frequency path is, the better the signal of the middle and low frequency band transmitted by the current first radio frequency path is. The smaller the transmission power margin of the first radio frequency path is, the worse the signal of the middle and low frequency band transmitted by the current first radio frequency path is. Based on this, the transmission power level of the second radio frequency path can be adjusted according to the transmission power margin of the first radio frequency path, so as to ensure uplink coverage of the 5G NR radio frequency signal, and simultaneously, the power consumption of the electronic equipment can be reduced.
In an alternative embodiment, the transmit power margin of the first rf path may be determined based on the maximum transmit power and the actual transmit power of the first rf path. More specifically, the transmission power margin of the first rf path is the difference between the maximum transmission power of the first rf path and the actual transmission power. Wherein the maximum transmission power of the first radio frequency path may be determined according to the current transmission power level of the first radio frequency path. Different transmit power levels correspond to different maximum transmit powers. For example, if the transmit power level of the first rf path is PC2, the maximum transmit power corresponding to the transmit power level (PC2) is 26dBm, and the actual transmit power is 21dBm, the transmit power margin of the first rf path is 5 dBm.
In another alternative embodiment, the transmission power headroom may be directly carried in uplink information transmitted in the first radio frequency path, and the electronic device may determine the transmission power headroom of the first radio frequency path directly through the uplink information.
After step 2200, step 2300 is performed to adjust the transmit power level of the second rf path according to the transmit power headroom of the first rf path.
The transmit power level may reflect the transmit power capability of the radio frequency path. Different transmit power levels correspond to different maximum transmit powers. That is, the higher the transmit power level of the second radio frequency path, the greater the maximum transmit power of the second radio frequency path. The lower the transmit power level of the second radio frequency path, the lower the maximum transmit power of the second radio frequency path.
In this embodiment, the transmission power of the second rf path may be further adjusted by adjusting the transmission power level of the second rf path. Specifically, the larger the transmission power margin of the first radio frequency path is, the better the signal of the middle-low frequency band transmitted by the current first radio frequency path is, and the better the signal coverage of the middle-low frequency band is, at this time, the transmission power level of the second radio frequency path may be adjusted down to reduce the transmission power of the second radio frequency path, so that the power consumption of the electronic device is reduced while the uplink coverage of the 5G NR radio frequency signal is ensured. The smaller the transmission power margin of the first radio frequency path is, the worse the signal of the middle and low frequency band transmitted by the current first radio frequency path is, and the worse the signal coverage of the middle and low frequency band is, at this time, the transmission power level of the second radio frequency path can be increased to increase the transmission power of the second radio frequency path, thereby ensuring the uplink coverage of the 5G NR radio frequency signal.
In the embodiment of the application, the electronic device is controlled to switch to the first working state under the condition that the reference signal receiving power corresponding to the second radio frequency channel is smaller than the first threshold and the reference signal receiving power of the first radio frequency channel is larger than the second threshold, 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 simultaneously transmit the 5G NR radio frequency signals, and the uplink coverage of the 5G NR radio frequency signals can be ensured by utilizing the good coverage performance of the low-and-medium frequency signals, thereby satisfying the continuously improved 5G uplink service. Further, under the condition that the electronic device is in the first working state, the transmission power level of the second radio frequency channel is adjusted according to the transmission power margin of the first radio frequency channel, the transmission power level of the second radio frequency channel can be reduced under the condition that the transmission power margin of the first radio frequency channel is large, and the power consumption of the electronic device is reduced while the uplink coverage of the 5GNR radio frequency signal is ensured. And under the condition that the transmitting power margin of the first radio frequency channel is smaller, the transmitting power level of the second radio frequency channel is increased, and the uplink coverage of the 5G NR radio frequency signal is further improved.
In some embodiments of the present application, said adjusting the transmit power level of the second rf path according to the transmit power headroom of the first rf path comprises: and when the transmission power margin of the first radio frequency path is larger than a third threshold value, the transmission power level of the second radio frequency path is reduced.
The third threshold may measure how good the medium and low frequency signals transmitted by the first radio frequency path are. The third threshold value is determined according to the self-capability of the electronic device and the network environment in which the electronic device is located. In a specific implementation process, the third threshold may be set according to a test result, and the third threshold may be, for example, 10dBm, which is not limited in this embodiment of the present application.
When the transmission power margin of the first radio frequency path is greater than the third threshold, it is indicated that the signal of the middle-low frequency band transmitted by the current first radio frequency path is better, and the signal of the middle-low frequency band is better covered, at this time, the transmission power level of the second radio frequency path can be reduced, and the transmission power of the second radio frequency path can be further reduced, so that the power consumption of the electronic device is reduced while the uplink coverage of the 5G NR radio frequency signal is ensured. The smaller the transmit power margin of the first radio frequency path.
In some embodiments of the present application, said adjusting the transmit power level of the second rf path according to the transmit power headroom of the first rf path further comprises: and under the condition that the transmission power margin of the first radio frequency path is smaller than a fourth threshold value, the transmission power level of the second radio frequency path is increased.
The fourth threshold may measure how good the medium and low frequency signals transmitted by the first radio frequency path are. The fourth threshold value is determined according to the own capability of the electronic device and the network environment in which the electronic device is located. In a specific implementation process, the fourth threshold may be set according to a test result, which is not limited in this application.
When the transmission power margin of the first radio frequency path is smaller than the fourth threshold, it indicates that the signal of the middle-low frequency band transmitted by the current first radio frequency path is poor, and the signal coverage of the middle-low frequency band is poor, at this time, the transmission power level of the second radio frequency path can be increased, and the uplink coverage of the 5G NR radio frequency signal can be further improved.
In some embodiments of the present application, said adjusting the transmit power level of the second rf path according to the transmit power headroom of the first rf path further comprises: and controlling the transmission power level of the second radio frequency path to be kept unchanged under the condition that the transmission power margin of the first radio frequency path is greater than or equal to the fourth threshold and the transmission power margin of the first radio frequency path is less than or equal to the third threshold.
In some embodiments of the present application, after the adjusting the transmit power level of the second rf path according to the transmit power headroom of the first rf path, the method further comprises: and adjusting the transmitting power of the second radio frequency channel according to the transmitting power level of the second radio frequency channel.
In this embodiment, after the transmission power of the second rf path is adjusted, the transmission power of the second rf path is adjusted according to the flow of the wireless communication protocol, so as to adjust the transmission power of the second rf path according to actual needs.
In some embodiments of the present application, the electronic device further includes a third rf path, where the third rf path corresponds to the second network frequency band, that is, the third rf path and the second 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 the controlling electronic device switches to the first operating state, the method further includes: step 3100-step 3200.
And 3100, acquiring the reference signal receiving power of the second radio frequency path or the third radio frequency path when the electronic device is in the third working state.
The third working state is a state that the first radio frequency path transmits an LTE radio frequency signal, and the second 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.
