Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The application provides a voltage setting method, in which a first device can receive a voltage configuration of a minimum voltage value corresponding to a first voltage configuration interval from a second device. The minimum voltage value is determined from the first voltage configuration interval when the transmission power of the first device is equal to the target power and the adjacent channel power leakage ratio ACLR of the uplink signal is not less than the target ACLR. Therefore, the power consumption of the first equipment is reduced while the uplink performance requirement of the first equipment is ensured, and the standby time of the first equipment is prolonged.
The method and the device can be applied to scenes such as device application and device testing.
For example, please refer to fig. 1, which is a schematic structural diagram of a communication system according to an embodiment of the present application, and an application scenario of the device according to the embodiment of the present application may be the communication system shown in fig. 1. The communication system may include, but is not limited to, one or more first devices, one or more second devices, as exemplified by one first device and one second device in fig. 1. The number and form of the devices shown in fig. 1 are for example and not intended to limit the embodiments of the present application. The first device can send an uplink signal with target power, and the second device can obtain the adjacent channel power leakage ratio ACLR and the transmitting power of the uplink signal; furthermore, the second device determines the minimum voltage value corresponding to the first voltage configuration interval and sends the voltage configuration of the minimum voltage value corresponding to the first voltage configuration interval to the first device, so that the first device can call the voltage configuration of the minimum voltage value to send an uplink signal when working in the first voltage configuration interval, uplink performance is guaranteed, and power consumption is reduced.
For another example, a device test scenario described in the embodiment of the present application may be as shown in fig. 2, please refer to fig. 2, which is a schematic view of a scenario of device testing provided in the embodiment of the present application, where the scenario may include a first device, a second device, and a device testing apparatus. The functions of the first device and the second device may be as described in fig. 1, but the difference is that in fig. 2, the device testing apparatus may be configured to demodulate ACLR and transmit power of an uplink signal sent by the first device, and further send the ACLR and the transmit power of the uplink signal to the second device, so that the second device determines a minimum voltage value corresponding to the first voltage configuration interval according to the adjacent channel power leakage ratio ACLR and the transmit power of the uplink signal. The second device sends the voltage configuration of the minimum voltage value corresponding to the first voltage configuration interval to the first device, and the first device stores the voltage configuration of the minimum voltage value, so that the voltage configuration of the minimum voltage value corresponding to the first voltage configuration interval can be directly called when the first device is applied.
In this embodiment, the first device may be a terminal device, and the terminal device may also be referred to as a User Equipment (UE). The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical treatment (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), and the like.
In this embodiment, the second device in fig. 1 may be a network device, and the network device may be a device with a wireless transceiving function or a chip disposed on the device, where the network device includes but is not limited to: an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a network equipment controller (BSC), a network equipment transceiver station (BTS), a home network equipment (e.g., home evolved Node B or home Node B, HNB), a baseband unit (BBU), an Access Point (AP) in a wireless fidelity (WIFI) system, a wireless relay Node, a wireless backhaul Node, a transmission point (TRP or transmission point, TP), and the like, and may also be equipment used in systems of 4G, 5G, 6G, and the like. Optionally, the second device in fig. 2 may also be a computer or a personal computer, etc. for performing operations related to the second device in the embodiment of the present application.
Fig. 3 is a schematic flow chart of a voltage setting method according to an embodiment of the present application, which is illustrated from the perspective of interaction between a first device and a second device. The voltage setting method includes, but is not limited to, the steps of:
s101, first equipment sends an uplink signal with target power;
the first device includes a Power Amplifier (PA). A power amplifier, referred to as a "power amplifier," is an amplifier that produces maximum power output to drive a load.
The target power is the maximum power corresponding to the PA in the first equipment in the first voltage configuration interval. The first voltage allocation interval may be one of two voltage allocation intervals of the PA in the high gain mode, one of two voltage allocation intervals of the PA in the intermediate gain mode, or one of two voltage allocation intervals of the PA in the low gain mode. Therefore, the voltage setting method can support optimization of various voltage conversion configurations.
In addition, in the voltage setting method, the minimum voltage value of the PA is determined at the maximum power of each voltage configuration interval, and since the power consumption of the first device is maximum at the maximum power, the determination of the minimum voltage value is beneficial to reducing the power consumption of the first device to a greater extent.
For example, the PA power in the first voltage configuration interval includes 18dbm to 23dbm, where the maximum power is 23dbm, and then the target power or transmission power for the terminal to transmit the uplink signal is 23 dbm.
S102, the second equipment acquires the adjacent channel power leakage ratio ACLR and the transmitting power of the uplink signal;
the adjacent channel power leakage ratio (ACLR) is used to measure the influence characteristics of the rf device on the channel outside the main operating frequency. ACLR refers to the ratio of the power leaked on the on-channel to the power of the main channel, usually expressed in dbc. The larger the ACLR is, the smaller the leakage power of the main channel is, which means that the influence of the main channel on the adjacent channel is smaller, and the better the performance of the communication system is; the smaller the ACLR, the larger the leakage power of the main channel, which means that the main channel has a larger influence on the adjacent channel, and the worse the performance of the communication system. According to the embodiment of the application, the uplink performance is represented by the ACLR, so that the requirement of the uplink performance is ensured while the voltage is optimized.
In one embodiment, the second device obtains the ACLR and the transmission power of the uplink signal through detection of the uplink signal by receiving the uplink signal from the first device. For example, as shown in fig. 1, the second device detects an uplink signal sent by the first device, and demodulates the uplink signal to obtain the ACLR and the transmission power of the uplink signal.
In another embodiment, as shown in fig. 2, the second device obtains the ACLR and the transmit power of the uplink signal from the device testing apparatus. The equipment testing instrument can demodulate the ACLR and the transmitting power of the uplink signal from the first equipment in real time.
S103, the second equipment determines the minimum voltage value corresponding to the first voltage configuration interval;
wherein, S103 includes: and the second equipment determines the minimum voltage value corresponding to the first voltage configuration interval according to the ACLR and the transmitting power of the uplink signal. The minimum voltage value is a minimum voltage value determined from the first voltage configuration interval when the transmission power of the first device is equal to the target power and the ACLR is not less than the target ACLR.
Optionally, the target ACLR is set according to a communication system, and different target ACLRs may be set according to different communication systems. Optionally, the target ACLR may also be set according to a device type of the first device and a different communication system. For example, for a 3G handset product, the target ACLR can be set to-43 dbc.
S104, the second equipment sends the voltage configuration of the minimum voltage value corresponding to the first voltage configuration interval to the first equipment;
s105, the first device receives the voltage configuration of the minimum voltage value corresponding to the first voltage configuration interval from the second device;
s106, the first device stores the voltage configuration of the minimum voltage value.
Optionally, the voltage setting method may further include: the first device updates the voltage configuration of the PA in the signaling mode with the voltage configuration of the minimum voltage value.
It can be seen that the first device stores the voltage configuration of the minimum voltage value locally, which is advantageous for directly calling the voltage configuration of the minimum voltage value under signaling. Since most of the power consumption of the first device comes from the power amplifier, the voltage setting method reduces the power consumption of the PA by using the minimum voltage value of the PA, that is, reduces the power consumption of the first device, thereby being beneficial to prolonging the standby time of the first device.
In addition, the minimum voltage value determined in the embodiment of the present application is obtained under the condition that the ACLR of the uplink signal is not less than the target ACLR, so that the PA power consumption is automatically optimized under the condition that the uplink performance requirement is satisfied. Compared with the current voltage optimization method based on the mode of manually configuring the voltage by referring to the empirical value, the method not only avoids neglecting the power consumption for the performance, but also avoids the problem that the performance and the power consumption can not be considered simultaneously because the performance is influenced for the power consumption.
In addition, because the maximum power of the first device is stabilized at the set target power when the signaling works, the terminal takes the maximum power of the voltage configuration interval as the target power for transmitting the uplink signal for each voltage configuration interval in the embodiment of the present application, and it is ensured that the transmission power of the first device is stabilized at the target power under non-signaling. Therefore, the minimum voltage value determined under non-signaling is very close to the minimum voltage value determined under signaling, and the accuracy of the optimization result of the voltage setting method is improved.
As shown in fig. 4, fig. 4 is a graph illustrating a trend of an influence of a voltage of a PA on a transmission power of a first device under non-signaling and signaling according to an embodiment of the present application. As shown in fig. 4, when the transmission power of the first device is stabilized at the maximum power under non-signaling, a trend graph of the influence of the voltage of the PA on the transmission power of the first device is changed, and a trend graph of the influence of the voltage of the PA on the transmission power of the first device is changed by the first device under signaling.
Referring to fig. 5, fig. 5 is a schematic flow chart of another voltage setting method according to an embodiment of the present application. The voltage setting method shown in fig. 5 is different from the voltage setting method shown in fig. 3 in that the voltage setting method shown in fig. 5 further illustrates how the minimum voltage value corresponding to the first voltage configuration interval is determined by interaction between the first device and the second device. The voltage setting method includes, but is not limited to, the steps of:
s201, a first device sends an uplink signal with target power;
the relevant content of S201 can refer to the explanation of step S101 in fig. 3, and is not described herein again.
S202, the second equipment acquires the ACLR and the transmitting power of the uplink signal;
the relevant content of S202 can be referred to the explanation of step S102 in fig. 3, and is not described herein again.
S203, the second equipment judges whether the ACLR of the uplink signal is not less than the target ACLR; if the ACLR of the uplink signal is not less than the target ACLR, execute step S204;
before the second device determines whether the ACLR of the uplink signal is not less than the target ACLR, it needs to determine whether the transmission power of the uplink signal is equal to the target power. If the transmission power of the uplink signal is equal to the target power, step S203 is executed. It can be seen that this embodiment is advantageous to ensure that the voltage configuration optimally obtained in the non-signaling mode can be directly used for invocation in the signaling mode.
S204, the second equipment sends an adjusting instruction to the first equipment;
the adjustment instruction is used to instruct the first device to decrease the voltage of the PA and increase the uplink gain of the transceiver when the first device transmits the next uplink signal. Since the ACLR of the uplink signal is not less than the target ACLR, which indicates that the uplink performance has exceeded the uplink performance requirement corresponding to the target ACLR, the power consumption of the PA can be reduced by reducing the voltage value of the PA.
S205, the first device receives an adjusting instruction from the second device;
s206, the first device responds to the adjustment instruction, adjusts the voltage of the PA by the voltage reduction amount of the PA, and adjusts the uplink gain of the transceiver by the uplink gain increase amount of the transceiver;
further, the first device transmits the uplink signal by performing step S201 again with the adjusted PA voltage and the uplink gain of the transceiver. When the first device transmits the uplink signal with the transmission power equal to the target power, that is, the uplink signal is transmitted with the adjusted PA voltage and the uplink gain of the transceiver, the transmission power of the first device is stabilized at the target power, which is favorable for simulating a signaling mode to obtain a minimum voltage value applicable to signaling.
Further, the second device may continue to perform steps S202 and S203 until step S207 is performed if the ACLR of the uplink signal is smaller than the target ACLR.
And S207, the second device determines the voltage of the PA when the first device sends the last uplink signal, and the voltage is the minimum voltage value corresponding to the first voltage configuration interval.
That is, the second device determines a minimum voltage value corresponding to the first voltage configuration interval, including: if the voltage value is smaller than the target ACLR, the second equipment determines the voltage of the PA when the first equipment sends the last uplink signal, and the voltage value is the minimum voltage value corresponding to the first voltage configuration interval.
In another embodiment, if the second device determines that the ACLR of the uplink signal is smaller than the target ACLR when performing step S203 for the first time, that is, the initial ACLR of the uplink signal is smaller than the target ACLR, which indicates that the uplink performance of the first device does not meet the uplink performance requirement of the target ACLR, the second device may send an adjustment instruction to the first device, where the adjustment instruction is different from the above-mentioned adjustment instruction in that the adjustment instruction is used to instruct the first device to increase the voltage of the PA when sending the next uplink signal, so as to improve the uplink performance. Optionally, the first device may perform steps S201 and S202 again on the adjusted voltage of the PA, and if the ACLR of the uplink signal is not less than the target ACLR, use the voltage of the PA at this time as the minimum voltage of the first voltage configuration interval, so as to facilitate call during signaling.
Therefore, the minimum voltage value finally determined by the embodiment is larger than the initial voltage value, so that the voltage setting method can flexibly judge that the performance index is preferentially met by sacrificing power consumption when the initial ACLR cannot meet the uplink performance requirement.
S208, the second equipment sends the voltage configuration of the minimum voltage value corresponding to the first voltage configuration interval to the first equipment;
s209, the first device receives the voltage configuration of the minimum voltage value corresponding to the first voltage configuration interval;
s210, the first device stores the voltage configuration of the minimum voltage value corresponding to the first voltage configuration interval.
For example, taking an initial voltage of the PA in the first device as 3.2V as an example, the second device sends an adjustment instruction to the first device when the transmission power of the uplink signal is equal to the target power and the ACLR of the uplink signal is not less than the target ACLR, where the adjustment instruction is used to indicate that the voltage decrease of the PA is 0.1V and the uplink gain increase of the transceiver is 1 db when the first device sends the next uplink signal, and then the first device sends the uplink signal with the voltage of the PA being 3.1V and the uplink gain being 2; if the transmission power of the uplink signal acquired again by the second device is equal to the target power and the ACLR of the uplink signal is not less than the target ACLR, the second device sends the adjustment instruction to the first device again until the transmission power of the uplink signal acquired by the second device is equal to the target power and the ACLR of the uplink signal is less than the target ACLR when the voltage of the PA is 2.3V, and then the second device may determine that the voltage 2.4V of the PA which has transmitted the uplink signal last time is the minimum voltage corresponding to the voltage configuration interval.
As shown in table 1, the first voltage configuration interval in the high gain mode of the voltage converter configuration in the first device is denoted as H1, and the second voltage configuration interval is denoted as H2; in the intermediate gain mode of the voltage converter configuration, a first voltage configuration interval is marked as M1, and a second voltage configuration interval is marked as M2; the voltage configuration interval in the low gain mode of the voltage converter configuration is denoted as L1. The initial voltage values of the PAs corresponding to each voltage configuration interval are shown in table 1, and are respectively 3.2V, 2.05V, 1.2V, 0.65V, and 0.55V, and further, by using the voltage setting method described in the embodiment of the present application, the optimized minimum voltage values are respectively 2.4V, 1.55V, 0.95V, 0.7V, and 0.5V. Therefore, the voltage configuration interval of the first device under the signaling can directly call the corresponding minimum voltage value.
TABLE 1 initial voltage values and optimized minimum voltage values of PA
| Initial voltage value (V) | Minimum voltage value (V) | |
| H1 | 3.2 | 2.4 |
| H2 | 2.05 | 1.55 |
| M1 | 1.2 | 0.95 |
| M2 | 0.65 | 0.7 |
| L1 | 0.55 | 0.5 |
As can be seen from table 1, in the cases of H1, H2, M1, and L1, the minimum voltage value is significantly lower than the initial voltage value, which indicates that the voltage of the PA is significantly optimized, the uplink performance is ensured, and the power consumption of the PA is reduced, thereby reducing the power consumption of the first device. The optimized minimum voltage value corresponding to M2 is greater than the initial voltage value, so that the power consumption is sacrificed and the requirement of uplink performance is met preferentially.
Therefore, the voltage setting method according to the embodiment of the application can minimize the power consumption of the PA under the condition that the uplink performance is satisfied, further reduce the power consumption of the first device, prolong the standby time of the first device, and preferentially guarantee the uplink performance by sacrificing the power consumption when the uplink performance of the first device cannot be satisfied, thereby greatly improving the flexibility of voltage setting.
