technical field

The present application relates to the field of communication technologies, and in particular, to a method, an apparatus, and a user terminal for improving uplink performance.

Background technique

Radio frequency capability absorption ratio (also known as specific absorption rate, SAR, specific absorption rate) refers to the amount of radio frequency energy absorbed by a unit of body weight in a unit of time. At present, SAR is widely used to measure whether the impact of electromagnetic radiation of user terminals on the human body meets the standard. For example, the FCC certification standard introduced by the Federal Communications Commission (FCC) stipulates that the SAR value is 1.6 watts/kg (that is, within 6 minutes, the radio frequency energy absorbed per kilogram of human tissue is 1.6 watts). The European standard specifies a SAR value of 2 W/kg.

At present, the user terminal detects the current distance between each antenna and the human body through the sensor, and determines the current transmit power threshold corresponding to each antenna according to the distance and the SAR value (one can be selected from the SAR values specified in the above-mentioned different standards), The current transmit power threshold corresponding to each antenna is the maximum transmit power that meets the requirements of the RF capability absorption ratio SAR value at the current distance between the antenna and the human body. Subsequently, when the user terminal detects that the transmit power of the radio frequency sent on a certain antenna exceeds the current transmit power threshold of the antenna, it needs to reduce the transmit power of the radio frequency. Therefore, it is ensured that the total transmit power of the user terminal satisfies the transmit power corresponding to the SAR value specified in the standard.

However, after the user terminal reduces the transmit power, the uplink performance of the user terminal will be affected.

Detailed ways

The embodiments of the present application provide a method for improving uplink performance, which can be applied to a user terminal in a communication network. Specifically, it can be applied to a non-stand along (NSA) networking architecture based on dynamic shared power. user terminal. FIG. 1 is an architectural diagram of a communication network provided by an embodiment of the present application. As shown in FIG. 1 , the communication network includes an access network device and a user terminal. Wherein, the access network device and the user terminal can communicate through wireless technology.

It should be noted that the communication network may be a communication network supporting the fourth generation (4G) access technology, for example, the long term evolution (long term evolution, LTE) access technology; or, the communication network may also be A communication network supporting fifth generation (5G) access technology, for example, new radio (NR) access technology; alternatively, the communication network may also support third generation (3G) access technology communication network, for example, universal mobile telecommunications system (UMTS) access technology, 3rd Generation Partnership Project (3GPP); or the communication network may be second generation (second generation) Generation, 2G) access technology communication network, such as global system for mobile communications (global system for mobile communications, GSM) access technology; or, the communication network can also be a communication network supporting multiple wireless technologies, such as supporting LTE technology and NR technology communication network. In addition, the communication network can also be adapted to future-oriented communication technologies. The access network device in FIG. 1 may be a device on the access network side used to support terminal access to the communication system, for example, may be a base transceiver station (BTS) and a base station controller in a 2G access technology communication system A base station controller (BSC), a node B (node B) and a radio network controller (RNC) in a 3G access technology communication system, an evolved base station (evolved nodeB) in a 4G access technology communication system , eNB), next generation nodeB (gNB), transmission reception point (TRP), relay node (relay node), access point (access point, AP) in the 5G access technology communication system )and many more. A user terminal may be a device that provides voice or data connectivity to a user, for example, may also be referred to as user equipment (user equipment, UE), a mobile station (mobile station), a subscriber unit (subscriber unit), or a station (station). , terminal equipment (terminalequipment, TE) and so on. Also can be cellular phone, personal digital assistant (PDA), wireless modem (modem), handheld device (handheld), laptop computer (laptop computer), cordless phone (cordless phone), wireless local Loop (wireless local loop, WLL) station, tablet computer (pad) and so on. With the development of wireless communication technologies, devices that can access the communication system, communicate with the network side of the communication system, or communicate with other objects through the communication system can be the terminals in the embodiments of the present application, for example, intelligent transportation Terminals and automobiles in the smart home, household equipment in the smart home, power meter reading instruments in the smart grid, voltage monitoring instruments, environmental monitoring instruments, video monitoring instruments in the smart security network, cash registers, etc.

The user terminal includes at least two antennas. This embodiment is described by taking the user terminal including the first antenna and the second antenna as an example, and other situations are similar. The user equipment may transmit the first radio frequency signal to the access network device through the first antenna, and transmit the second radio frequency signal to the access network device through the second antenna; and may also transmit the second radio frequency to the access network device through the first antenna signal, the first radio frequency signal is transmitted to the access network device through the second antenna, the first radio frequency signal and the second radio frequency signal can also be transmitted to the access network device through the first antenna, and the access network device can also be transmitted through the second antenna. The first radio frequency signal and the second radio frequency signal are transmitted, which is not limited in this embodiment of the present application.

It should be noted that, in some embodiments, the user terminal is a terminal that supports the NSA networking architecture and is capable of dynamic power sharing. Further, the first radio frequency signal belongs to the signal of the primary cell under the NSA networking architecture where the user terminal is located. The second radio frequency signal belongs to the signal of the secondary cell under the NSA networking architecture where the user terminal is located.

In some embodiments, the user terminal may be a terminal that supports the NSA networking architecture and has dynamic power sharing capability. When the LTE network is used as the primary cell under the NSA networking architecture where the user terminal is located, the NR network is used as the NSA group where the user terminal is located. When the secondary cell under the network architecture is used, the first radio frequency signal is an LTE signal, and the second radio frequency signal is an NR signal. Both the first radio frequency signal and the second radio frequency signal mentioned herein may include one or more signals.

In the NSA networking based on dynamic shared power, the access network equipment can send control signaling to the user terminal through the downlink control channel. The control signaling includes the transmit power of the first radio frequency signal and the transmit power of the second radio frequency signal of the user terminal in each time slot (slot).

For example, FIG. 2A is a schematic diagram of dynamic power sharing provided by an embodiment of the present application. As shown in FIG. 2A , the maximum transmit power of the user terminal (that is, the maximum transmit power of the signal that the user terminal itself can transmit) is 25dbm. Wherein, in the first time slot, the transmit power of the first radio frequency signal is 15dbm, and the transmit power of the second radio frequency signal is 10dbm; in the second time slot, the transmit power of the first radio frequency signal is 10dbm, and the transmit power of the second radio frequency signal is 10dbm. In the third time slot, the transmit power of the first radio frequency signal is 20dbm, and the transmit power of the second radio frequency signal is 5dbm; in the fourth time slot, the transmit power of the first radio frequency signal is 15dbm, The transmit power of the second radio frequency signal is 10dbm.

It should be noted that, in the NSA networking based on dynamic shared power, an access network device (such as a base station) may also allocate transmit power for the first radio frequency signal and the second radio frequency signal according to the current network environment. For example, the control signaling is carried in the first radio frequency signal (such as an LTE signal), and the access network device can allocate the remaining transmit power to the second radio frequency signal (such as NR on the basis of preferentially satisfying the transmit power of the first radio frequency signal). Signal). For example, the maximum transmit power of the user terminal is 25dbm. When the distance between the user terminal and the access network equipment is long, the access network equipment preferentially satisfies the transmit power of the first radio frequency signal, and the transmit power allocated for the first radio frequency signal is 24dbm , the transmit power allocated for the second radio frequency signal is 1dbm; when the distance between the user terminal and the access network equipment is relatively short, the access network equipment preferentially satisfies the transmit power of the first radio frequency signal, and the transmit power allocated for the first radio frequency signal is 5dbm, and the transmission power allocated for the second radio frequency signal is 20dbm.

The user terminal further includes a sensor, a first modem corresponding to the first radio frequency signal, and a second modem corresponding to the second radio frequency signal. The sensor is used to continuously detect the first distance between the first antenna and the human body and the second distance between the second antenna and the human body according to the preset detection period, and compare the detected first distance and the second distance. The distances are sent to the first and second modems, respectively. The first modem is configured to determine the first current transmit power threshold corresponding to the first antenna according to the first distance and the SAR. Similarly, the second modem is configured to determine the second current transmit power threshold corresponding to the second antenna according to the second distance and the SAR. Subsequently, when the first modem detects that the current transmit power of the first radio frequency signal is greater than the first current transmit power threshold, the first modem may reduce the transmit power of the first radio frequency signal. Similarly, when the second modem detects that the current transmit power of the second radio frequency signal is greater than the second current transmit power threshold, the second modem can reduce the transmit power of the second radio frequency signal. In this way, it can be ensured that the transmit power of the user terminal satisfies the transmit power corresponding to the SAR specified in the standard. However, it will cause the current total transmit power of the user terminal (for example, the sum of the transmit power currently used by the user terminal to transmit the first radio frequency signal and the second radio frequency signal) to be less than the maximum transmit power of the user terminal, thereby affecting the uplink of the user terminal. performance. It should be noted that both the first radio frequency signal and the second radio frequency signal may only correspond to the same modem. In this embodiment of the present application, the first radio frequency signal corresponds to the first modem and the second radio frequency signal corresponds to the second modem as an example for introduction. Other situations are similar.

For example, FIG. 2B is a schematic diagram of dynamic power sharing after SAR reduction provided by an embodiment of the present application, as shown in FIG. 2B . In the first time slot, the current transmit power of the first radio frequency signal is 15dbm, and the current transmit power of the second radio frequency signal is 10dbm. Assuming that in the first time slot, the first current transmit power threshold is 10dbm, and the second current transmit power is 10dbm. The power threshold is 15dbm. At this time, since the current transmit power of the first radio frequency signal is 15dbm, which exceeds the first current transmit power threshold, the first modem reduces the current transmit power of the first radio frequency signal to 10dbm, thereby allowing the user to The current total transmit power of the terminal is reduced to 20 dbm, resulting in the current total transmit power of the user terminal being less than the maximum transmit power of the user terminal, which is 25 dbm, thus causing power waste and affecting the uplink performance of the user terminal. For another example, in the third time slot, the current transmit power of the first radio frequency signal is 20dbm, and the current transmit power of the second radio frequency signal is 5dbm. Suppose that in the third time slot, the first current transmit power threshold is 10dbm, and the 2. The current transmit power threshold is 10dbm. At this time, since the current transmit power of the first radio frequency signal is 20dbm, which exceeds the first current transmit power threshold, the first modem reduces the current transmit power of the first radio frequency signal to 10dbm, so that the current total transmit power of the user terminal is reduced. The power is reduced to 15dbm. As a result, the current total transmit power of the user terminal is less than the maximum transmit power of the user terminal by 25 dbm, thereby causing power waste and affecting the uplink performance of the user terminal. For another example, in the fourth time slot, the current transmit power of the first radio frequency signal is 15dbm, and the current transmit power of the second radio frequency signal is 10dbm, assuming that in the fourth time slot, the first current transmit power threshold is 5dbm, and the 2. The current transmit power threshold is 10dbm. At this time, since the current transmit power of the first radio frequency signal is 15dbm, which exceeds the first current transmit power threshold, the first modem reduces the current transmit power of the first radio frequency signal to 5dbm, so that the current total transmit power of the user terminal is reduced. The power is reduced to 15dbm. As a result, the current total transmit power of the user terminal is less than the maximum transmit power of the user terminal by 25 dbm, thereby causing power waste and affecting the uplink performance of the user terminal.

It should be noted that the sensor may also send the detected second distance to the first modem. Correspondingly, the first modem may determine the second current transmit power threshold corresponding to the second antenna according to the second distance and the SAR. Similarly, the sensor can also send the detected first distance to the second modem. Correspondingly, the second modem may determine the first current transmit power threshold corresponding to the first antenna according to the first distance and the SAR.

Some embodiments provided by this application are introduced in different scenarios as follows:

1. For the scenario where the user terminal supports antenna switching, and the first radio frequency signal will perform antenna switching:

When the first transmit power of the first radio frequency signal is greater than the current transmit power threshold of the first antenna described by the first radio frequency signal, and the current transmit power threshold of at least one antenna is less than the current transmit power threshold of the first antenna, or, When the first transmit power of the first radio frequency signal is less than or equal to the current transmit power threshold of the first antenna described by the first radio frequency signal, and there is at least one antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna, The user terminal may switch the first radio frequency signal to the first target antenna, and transmit the first radio frequency signal according to the first target transmit power. The first target transmit power is the smaller of the first transmit power and the first current transmit power threshold of the first target antenna.

(1) For the case where the user terminal transmits different radio frequency signals through different antennas

The first current transmit power threshold of the first target antenna may be the current transmit power threshold of the antenna whose forward direction is closest to the first transmit power among the current transmit power thresholds of each antenna. Subsequently, if the first target transmit power is lower than the first transmit power, the power of the second radio frequency signal may be boosted when the uplink is limited, and may be transmitted on the second target antenna with the second target transmit power. Among them, the second target antenna has the largest current transmit power threshold among other antennas other than the first target antenna; if the first target transmit power is equal to the first transmit power, the second radio frequency signal is transmitted on the third target antenna with the third The target transmit power is used to transmit, the third target antenna is the current transmit power threshold of the antenna whose current transmit power threshold is closest to the second transmit power in the forward direction of other antennas except the first target antenna, and the third target transmit power is the third The smaller of the current transmit power threshold of the target antenna and the second transmit power.

(2) For the case where the user terminal transmits different radio frequency signals through the same antenna

The current transmit power threshold of the first target antenna may be the largest among the current transmit power thresholds of the respective antennas. Subsequently, the second radio frequency signal may also be switched to the first target antenna and transmitted at the fourth target transmit power. If the first target transmit power is lower than the first transmit power, the power of the second radio frequency signal can be boosted when the uplink is limited. Wherein, the fourth target transmit power is the power after the second radio frequency signal is raised. If the first target transmit power is equal to the first transmit power, the fourth target transmit power is the smaller of the current transmit power threshold of the first target antenna and the second transmit power.

2. The user terminal supports antenna switching, but the first radio frequency signal does not need to switch the antenna according to the situation.

If the current transmit power threshold of the first antenna to which the first radio frequency signal currently belongs is the antenna whose forward direction is closest to the first transmit power among the current transmit power thresholds of the antennas, the user terminal can transmit through the first antenna according to the first target transmit power first radio frequency signal. The first target transmit power is the smaller of the first transmit power and the current transmit power threshold of the first antenna.

(1) For the situation that the user terminal transmits different radio frequency signals through different antennas, the following scheme can be adopted:

If the first target transmit power is lower than the first transmit power, the power of the second radio frequency signal can be boosted when the uplink is limited, and can be transmitted on the second target antenna with the second target transmit power. Wherein, the second target antenna is the antenna with the largest current transmit power threshold among other antennas except the first antenna, and the second target transmit power is the power after the second radio frequency signal is raised. If the first target transmit power is equal to the first transmit power, the second radio frequency signal is transmitted on the third target antenna with the third target transmit power. The third target antenna is the antenna whose current transmit power threshold is closest to the second transmit power in the forward direction among other antennas except the first antenna, and the third target transmit power is the current transmit power threshold of the third target antenna and the second transmit power The smaller of the power.

(2) For the case where the user terminal transmits different radio frequency signals through the same antenna, the following scheme may be adopted: the second radio frequency signal is transmitted on the first antenna with the fourth target transmit power. If the first target transmit power is lower than the first transmit power, the power of the second radio frequency signal can be boosted when the uplink is limited. Wherein, the fourth target transmit power is the power after the second radio frequency signal is raised. If the first target transmit power is equal to the first transmit power, the fourth target transmit power is the smaller of the current transmit power threshold of the first antenna and the second transmit power.

3. For scenarios where the user terminal does not support antenna switching

When the first transmit power of the first radio frequency signal is greater than the current transmit power threshold of the first antenna to which the first radio frequency signal belongs, the user terminal may transmit the first radio frequency signal according to the current transmit power threshold of the first antenna. At the same time, the user terminal can increase the transmit power of the second radio frequency signal when the uplink of the second radio frequency signal is limited.

Some embodiments of the present application provide a method for improving uplink performance. As shown in Figure 3, the specific processing flow is as follows:

Step 301: Obtain first transmit power corresponding to one or more first radio frequency signals to be transmitted.

The first transmit power is the transmit power allocated for the first radio frequency signal by the base station connected to the user terminal.

In implementation, in implementation, the user terminal may continuously detect the first transmit power corresponding to the first radio frequency signal according to the preset first detection period. The first transmit power may be the transmit power allocated for the first radio frequency signal by the base station to which the user equipment is connected.

Step 302, at least two antennas are used for the user terminal to transmit the first radio frequency signal and the second radio frequency signal through different antennas, when the first transmit power is greater than the current transmit power threshold of the first antenna to which the first radio frequency signal currently belongs, and at least When there is at least one antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna in at least one of the two antennas except the first antenna, then at least one current transmit power threshold is greater than the current transmit power of the first antenna. Among the antennas with the threshold value, the first target antenna whose first current transmit power threshold is closest to the first transmit power in the forward direction is determined.

In implementation, the user terminal may continuously detect the distance between each antenna and the human body according to the preset second detection period. Then, for each antenna, the user terminal may determine the current transmit power threshold corresponding to the antenna according to the distance between the antenna and the human body and the SAR. The second detection period may be the same as or different from the above-mentioned first detection period. The embodiments of the present application are not limited.

In the case where the user terminal transmits different radio frequency signals through different antennas, when the user terminal detects that the first transmit power is greater than the current transmit power threshold of the first antenna to which the first radio frequency signal currently belongs, and the antennas other than the first antenna When there is an antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna, the user terminal may determine the difference between the first current transmit power threshold and the first antenna from the antennas whose current transmit power threshold is greater than the current transmit power threshold of the first antenna. The transmit power is directed towards the closest first target antenna. Wherein, for different antennas, their current transmit power thresholds are also different. The embodiment of the present application provides two examples of the user terminal determining the first target antenna, as follows:

Example 1, if at least one antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna has at least one antenna whose current transmit power threshold is greater than or equal to the first transmit power, the first target antenna is at least one current transmit power threshold greater than or equal to The smallest among the current transmit power thresholds corresponding to each antenna among the antennas of the first transmit power.

In implementation, when the user terminal detects that the first transmit power is greater than the current transmit power threshold of the first antenna to which the first radio frequency signal currently belongs, and there is a current transmit power threshold greater than the current transmit power threshold of the first antenna in the antennas except the first antenna When an antenna with a transmit power threshold is used, the user terminal can determine whether there is an antenna greater than or equal to the first transmit power among the antennas whose current transmit power threshold is greater than the current transmit power threshold of the first antenna. If there is, the user terminal selects the antenna with the smallest current transmit power threshold corresponding to each antenna among the antennas whose current transmit power threshold is greater than or equal to the first transmit power, as the first target antenna. In this way, on the basis of ensuring that the user terminal transmits the first radio frequency signal according to the first transmit power, the antenna with a larger current transmit power threshold is reserved for the second radio frequency signal, which can further ensure that the second radio frequency signal is limited in uplink performance. In this case, the transmit power of the second radio frequency signal is increased as much as possible.

For example, if the first transmit power is 13dbm, the current transmit power threshold of the first antenna is 10dbm, the current transmit power threshold of the second antenna is 15dbm, and the current transmit power threshold of the third antenna is 17dbm, the user terminal selects the second antenna as the a target antenna.

Example 2, if at least one current transmit power threshold is greater than the current transmit power threshold of the first antenna, the current transmit power threshold of each antenna is smaller than the first transmit power of the antenna, then the first target antenna is at least one current transmit power threshold. Among the antennas that are greater than the current transmit power threshold of the first antenna, the current transmit power threshold of each antenna is the largest.

In implementation, when the user terminal detects that the first transmit power is greater than the current transmit power threshold of the first antenna to which the first radio frequency signal currently belongs, and there is a current transmit power threshold greater than the current transmit power threshold of the first antenna in the antennas except the first antenna When the antenna with the transmit power threshold is used, the user terminal can check whether the current transmit power threshold of each antenna of the antennas whose current transmit power threshold is greater than the current transmit power threshold of the first antenna is smaller than that of the first transmit power. If the antennas are all smaller than the first transmit power, the user terminal may select the antenna with the largest current transmit power threshold among the antennas whose current transmit power threshold is greater than the current transmit power threshold of the first antenna, as the first target antenna. In this way, the user terminal can transmit the first radio frequency signal according to the current transmit power threshold of the first target antenna, thereby increasing the transmit power of the first radio frequency signal as much as possible.

For example, if the first transmit power is 15dbm, the current transmit power threshold of the first antenna is 10dbm, the current transmit power threshold of the second antenna is 12dbm, and the current transmit power threshold of the third antenna is 14dbm, the user terminal selects the third antenna as the third antenna. a target antenna.

In some embodiments, when the first transmit power is less than the current transmit power threshold of the first antenna to which the first radio frequency signal currently belongs, and there is at least one current transmit power in at least one of the at least two antennas except the first antenna When the threshold is less than the current transmit power threshold of the first antenna and is greater than or equal to the first transmit power, then there is at least one current transmit power threshold from at least one antenna that is less than the current transmit power threshold of the first antenna and greater than or equal to the first transmit power threshold. Among the antennas of transmit power, a first target antenna whose first current transmit power threshold is closest to the first transmit power in the forward direction is determined, and the first target antenna is at least one current transmit power threshold smaller than the current transmit power threshold of the first antenna and The smallest of the current transmit power thresholds of each antenna among the antennas with a transmit power greater than or equal to the first.

In implementation, for the case where the user terminal transmits different radio frequency signals through different antennas, when the first transmit power is less than the current transmit power threshold of the first antenna to which the first radio frequency signal currently belongs, and the antennas other than the first antenna When there is an antenna whose current transmit power threshold is less than the current transmit power threshold of the first antenna and is greater than or equal to the first transmit power, the user terminal can start from the current transmit power threshold less than the current transmit power threshold of the first antenna and greater than or equal to the first transmit power. Among the antennas with high power, the antenna with the smallest current transmit power threshold is selected as the first target antenna. In this way, on the basis of ensuring that the user terminal transmits the first radio frequency signal according to the first transmit power, the antenna with a larger current transmit power threshold is reserved for the second radio frequency signal, which can further ensure that the second radio frequency signal is limited in uplink performance. In this case, the transmit power of the second radio frequency signal is increased as much as possible.

For example, if the first transmit power is 10dbm, the current transmit power threshold of the first antenna is 15dbm, the current transmit power threshold of the second antenna is 12dbm, and the current transmit power threshold of the third antenna is 14dbm, the user terminal selects the second antenna as the a target antenna.

In some embodiments, at least two antennas are used for the user terminal to transmit the first radio frequency signal and the second radio frequency signal through the same antenna, when there is at least one current transmission in at least one of the at least two antennas except the first antenna When the power threshold is greater than the current transmit power threshold of the first antenna, the first target antenna is determined from at least one antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna. The current transmit power threshold is the largest among the current transmit power thresholds of each antenna among the at least one antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna.

In implementation, in the case where the user terminal transmits different radio frequency signals through the same antenna, when there is an antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna in the antennas other than the first antenna, the user terminal can From the antennas whose current transmit power threshold is greater than the current transmit power threshold of the first antenna, select the antenna with the largest current transmit power threshold of each antenna among the antennas whose current transmit power threshold is greater than the current transmit power threshold of the first antenna, as the first antenna target antenna.

For example, if the first transmit power is 10dbm, the current transmit power threshold of the first antenna is 15dbm, the current transmit power threshold of the second antenna is 12dbm, and the current transmit power threshold of the third antenna is 14dbm, the user terminal selects the third antenna as the a target antenna.

For another example, if the first transmit power is 15dbm, the current transmit power threshold of the first antenna is 10dbm, the current transmit power threshold of the second antenna is 25dbm, and the current transmit power threshold of the third antenna is 20dbm, the user terminal selects the second antenna as the The first target antenna.

In some embodiments, when the current transmit power threshold of each antenna in at least one of the at least two antennas except the first antenna is less than or equal to the current transmit power threshold of the first antenna, the first target antenna is For the first antenna, the first current transmit power threshold of the first target antenna is the current transmit power threshold of the first antenna.

In the implementation, for the case where the user terminal transmits different radio frequency signals through different antennas or for the case where the user terminal transmits different radio frequency signals through the same antenna, when the current transmit power threshold of each antenna in the antennas except the first antenna is When all the antennas are less than or equal to the current transmit power threshold of the first antenna, the user terminal may select the first antenna as the first target antenna.

For example, if the first transmit power is 10dbm, the current transmit power threshold of the first antenna is 15dbm, the current transmit power threshold of the second antenna is 12dbm, and the current transmit power threshold of the third antenna is 14dbm, the user terminal selects the first antenna as the a target antenna.

For another example, if the first transmit power is 20dbm, the current transmit power threshold of the first antenna is 15dbm, the current transmit power threshold of the second antenna is 12dbm, and the current transmit power threshold of the third antenna is 14dbm, the user terminal selects the first antenna as the The first target antenna.

Step 303: Determine the first target transmit power according to the first transmit power and the first current transmit power threshold.

In implementation, after determining the first target antenna for transmitting the first radio frequency signal, the user terminal may determine the first target transmission corresponding to the first radio frequency signal according to the first transmit power and the first current transmit power threshold of the first target antenna power.

In implementation, after determining the first target antenna for transmitting the first radio frequency signal, the user terminal may determine the first target transmit power corresponding to the first radio frequency signal according to the first transmit power and the first current transmit power threshold of the first target antenna .

In some embodiments, the user terminal determines the first target transmit power according to the first transmit power and the first current transmit power threshold corresponding to the first target antenna. The process is as follows:

Step 1, judging whether the first transmit power is greater than the first current transmit power threshold.

In implementation, the user terminal may determine whether the first transmit power is greater than the first current transmit power threshold corresponding to the first target antenna. If the first transmit power is greater than the first current transmit power threshold, the user terminal may perform step 2. If the first transmit power is not greater than the first current transmit power threshold, the user terminal may perform step three.

Step 2, taking the first current transmit power threshold as the first target transmit power.

In implementation, if the first transmit power is greater than the first current transmit power threshold, it means that the user terminal needs to reduce the transmit power of the first radio frequency signal, and the user terminal may use the first current transmit power threshold as the first target transmit power.

For example, the first transmit power is 20dbm, and the first current transmit power threshold is 15dbm. The first transmit power is greater than the first current transmit power threshold, indicating that the user terminal needs to reduce the transmit power of the first radio frequency signal, and the first target transmit power is 15dbm.

Step 3, taking the first transmit power as the first target transmit power.

In implementation, if the first transmit power is less than or equal to the first current transmit power threshold, it means that the user terminal does not need to reduce the transmit power of the first radio frequency signal, and the user terminal can use the first transmit power as the first target transmit power.

For example, the first transmit power is 10dbm, and the first current transmit power threshold is 15dbm. The first transmit power is less than the first current transmit power threshold, indicating that the user terminal does not need to reduce the transmit power of the first radio frequency signal, and the first target transmit power is 10 dbm.

Step 304: Transmit one or more first radio frequency signals to be transmitted through the first target antenna according to the first target transmit power.

In implementation, after determining the first target antenna and the first target transmit power corresponding to the first radio frequency signal, the user terminal may transmit the first radio frequency signal according to the first target transmit power through the first target antenna. In this way, the user terminal can reduce the reduction value of the current transmit power of the first radio frequency signal, thereby increasing the current total transmit power of the user terminal, thereby improving the uplink performance of the user terminal.

In some embodiments, after the transmit power of the first transmit signal is reduced, the user terminal may select an appropriate second target antenna to transmit the second radio frequency information. For the situation that the user terminal transmits different radio frequency signals through different antennas and the situation that the user terminal transmits different radio frequency signals through the same antenna, the method for the user terminal to select the second target antenna is also different, as follows:

Manner 1, for the case where the user terminal transmits different radio frequency signals through different antennas, the processing process is as follows:

Step 110: If the first transmit power is greater than the first current transmit power threshold, obtain the second transmit power corresponding to the one or more second radio frequency signals to be transmitted, and select at least one of the at least two antennas except the first target antenna. In one antenna, a second target antenna is determined, and the second current transmit power threshold of the second target antenna is the largest among the current transmit power thresholds of each antenna in the at least one antenna.

The second transmit power is the transmit power allocated by the connected base station for the second radio frequency signal.

In implementation, if the first transmit power is greater than the first current transmit power threshold, the user terminal transmits the first radio frequency signal through the first target antenna according to the first current transmit power threshold, that is, the transmit power of the first radio frequency signal is reduced. The user terminal may acquire the second transmit power corresponding to the second radio frequency signal to be transmitted. The second transmit power is the transmit power allocated by the connected base station for the second radio frequency signal. Then, the user terminal may select the antenna with the largest current transmit power threshold from the antennas other than the first target antenna as the second target antenna. In this way, it can be ensured that the user terminal can increase the transmit power of the second transmit power as much as possible.

Step 120, if the second transmit power is less than the second current transmit power threshold, determine the second target transmit power according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power and the maximum transmit power corresponding to the user terminal power.

The second target transmit power is less than or equal to the second current transmit power threshold, and the sum of the second target transmit power and the first current transmit power threshold is less than or equal to the maximum transmit power.

In implementation, after determining the second target antenna, the user terminal may further determine whether the second transmit power is smaller than the second current transmit power threshold corresponding to the second target antenna. If the second transmit power is less than the second current transmit power threshold, the user terminal may determine the second target transmit power according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power and the maximum transmit power corresponding to the user terminal power. The second target transmit power is less than or equal to the second current transmit power threshold, and the sum of the second target transmit power and the first current transmit power threshold is less than or equal to the maximum transmit power.

Optionally, according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power, and the maximum transmit power corresponding to the user terminal, the process for determining the second target transmit power by the user terminal is as follows:

Step 121: Determine a transmit power boost value corresponding to the second radio frequency signal according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power, and the maximum transmit power corresponding to the user terminal.

In implementation, the user terminal may determine the transmit power boost value corresponding to the second radio frequency signal according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power and the maximum transmit power corresponding to the user terminal.

Optionally, the user terminal determines, according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power, and the maximum transmit power corresponding to the user terminal, the processing process for determining the transmit power boost value corresponding to the second radio frequency signal as follows:

Step 1211: Determine a second difference between the second current transmit power threshold and the second transmit power.

In an implementation, the user terminal may calculate a second difference between the second current transmit power threshold and the second transmit power. Wherein, the second difference is the maximum value that the user terminal can increase the transmit power of the second radio frequency signal on the basis of satisfying the SAR requirement.

Step 1212: Determine the first current transmit power threshold and the second sum of the second transmit power, and determine the third difference between the maximum transmit power corresponding to the user terminal and the second sum.

In implementation, the user terminal may also first determine the first current transmit power threshold and the second sum value of the second transmit power. Wherein, the second sum value is the current total transmit power of the user terminal. Then, the user terminal may determine a third difference between the maximum transmit power corresponding to the user terminal (ie, the maximum transmit power that the user terminal can transmit signals with its own capability) and the second sum value. Wherein, the third difference is a maximum value that can increase the transmit power of the second radio frequency signal on the basis that the user terminal satisfies the maximum transmit power.

After determining the second difference and the third difference, the user terminal may further determine whether the second difference is greater than the third difference. If the second difference is greater than the third difference, the user terminal executes step 213 . If the second difference is less than or equal to the third difference, the user terminal performs step 214 .

Step 1213: Use the third difference as the transmit power boost value corresponding to the second radio frequency signal.

In implementation, if the second difference value is greater than the third difference value, the user terminal may use the third difference value as the transmit power boost value corresponding to the second radio frequency signal.

Step 1214: Use the second difference as the transmit power boost value corresponding to the second radio frequency signal.

In implementation, if the second difference value is less than or equal to the third difference value, the user terminal may use the second difference value as the transmit power boost value corresponding to the second radio frequency signal.

Step 122: Use the second transmit power and the first sum of the transmit power boost value as the second target transmit power.

In implementation, after determining the transmit power boost value corresponding to the second radio frequency signal, the user terminal may use the first sum of the second transmit power and the transmit power boost value as the second target transmit power of the second radio frequency signal.

Step 130: Transmit one or more second radio frequency signals to be transmitted through the second target antenna according to the second target transmit power.

In implementation, after determining the second target transmit power of the second radio frequency signal, the user terminal may transmit the second radio frequency signal according to the second target transmit power through the second target antenna. In this way, the user terminal can increase the transmit power of the second radio frequency signal as much as possible.

In the second way, for the case where the user terminal transmits different radio frequency signals through the same antenna, the processing process is as follows:

Step 210, if the first transmit power is greater than the first current transmit power threshold, obtain the second transmit power corresponding to the one or more second radio frequency signals to be transmitted, and determine the second target antenna from the at least two antennas, The second current transmit power threshold of the second target antenna is the largest among the current transmit power thresholds of each of the at least two antennas.

The second transmit power is the transmit power allocated by the connected base station for the second radio frequency signal.

In implementation, if the first transmit power is greater than the first current transmit power threshold, the user terminal transmits the first radio frequency signal through the first target antenna according to the first current transmit power threshold, that is, the transmit power of the first radio frequency signal is reduced. The user terminal may acquire the second transmit power corresponding to the second radio frequency signal to be transmitted. The second transmit power is the transmit power allocated by the connected base station for the second radio frequency signal. Then, the user terminal may select the antenna with the largest current transmit power threshold from the antennas as the second target antenna. In this way, it can be ensured that the user terminal can increase the transmit power of the second transmit power as much as possible.

Step 220, if the second transmit power is less than the second current transmit power threshold, then according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power and the maximum transmit power corresponding to the user terminal, determine the second target transmit power.

The second target transmit power is less than or equal to the second current transmit power threshold, and the sum of the second target transmit power and the first current transmit power threshold is less than or equal to the maximum transmit power.

In implementation, after determining the second target antenna, the user terminal may further determine whether the second transmit power is smaller than the second current transmit power threshold corresponding to the second target antenna. If the second transmit power is less than the second current transmit power threshold, the user terminal may determine the second target transmit power according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power and the maximum transmit power corresponding to the user terminal power. The second target transmit power is less than or equal to the second current transmit power threshold, and the sum of the second target transmit power and the first current transmit power threshold is less than or equal to the maximum transmit power. The process of determining the second target transmit power by the user terminal according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power, and the maximum transmit power corresponding to the user terminal is similar to the above step 120, and will not be repeated here. .

Step 230: Transmit one or more second radio frequency signals to be transmitted through the second target antenna according to the second target transmit power.

In implementation, after determining the second target transmit power of the second radio frequency signal, the user terminal may transmit the second radio frequency signal according to the second target transmit power through the second target antenna. In this way, the user terminal can increase the transmit power of the second radio frequency signal as much as possible.

Optionally, before the user terminal determines the second target transmission power according to the second current transmission power threshold, the first current transmission power threshold, the second transmission power, and the maximum transmission power corresponding to the user terminal, the user terminal may further determine the second target transmission power according to the second radio frequency signal. The downlink path loss of , determines the second target transmit power, and the processing process is as follows:

Step 1: Obtain the current downlink path loss corresponding to the second radio frequency signal.

In implementation, the user terminal may continuously detect the current downlink path loss of the second radio frequency signal according to the preset third detection period. The first detection period, the second detection period and the third detection period may be the same or different. The embodiments of the present application are not limited.

Step 2: Determine whether the current downlink path loss is greater than a pre-stored downlink path loss threshold.

In implementation, the downlink path loss threshold may be pre-stored in the user terminal. The downlink path loss threshold can be set by technicians according to experience. After obtaining the current downlink path loss of the second radio frequency signal, the user terminal can determine whether the current downlink path loss value of the second radio frequency signal is greater than the pre-stored downlink path loss threshold. If the current downlink path loss value of the second radio frequency signal is greater than the pre-stored downlink path loss threshold, step 3 is performed. If the current downlink path loss value of the second radio frequency signal is less than or equal to the pre-stored downlink path loss threshold, step 4 is performed.

Step 3: Determine the second target transmit power according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power and the maximum transmit power corresponding to the user terminal.

In implementation, if the current downlink path loss value of the second radio frequency signal is greater than the pre-stored downlink path loss threshold, the user equipment The corresponding maximum transmit power is used to determine the second target transmit power. The process of determining the second target transmit power by the user terminal according to the second current transmit power threshold, the first current transmit power threshold, the second transmit power and the maximum transmit power corresponding to the user terminal is similar to the above step 120. Repeat.

Step 4: Use the second transmit power as the second target transmit power of the second radio frequency signal, and transmit one or more second radio frequency signals to be transmitted through the second antenna according to the second target transmit power.

In implementation, if the current downlink path loss value of the second radio frequency signal is less than or equal to the pre-stored downlink path loss threshold, the second transmit power is used as the second target transmit power of the second radio frequency signal, and the second antenna is used according to The second target transmit power transmits one or more second radio frequency signals to be transmitted.

In a method for improving uplink performance provided by an embodiment of the present application, a user terminal acquires first transmit power corresponding to one or more first radio frequency signals to be transmitted. When the first transmit power is greater than the current transmit power threshold of the first antenna to which the first radio frequency signal currently belongs, and there is at least one current transmit power threshold in at least one of the at least two antennas except the first antenna that is greater than the current transmit power threshold of the first antenna When the antenna has the current transmit power threshold, the user terminal determines, from at least one antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna, the first current transmit power threshold that is closest to the first transmit power in the forward direction. a target antenna. Then, the user terminal determines the first target transmit power according to the first transmit power and the first current transmit power threshold. After that, the user terminal transmits one or more first radio frequency signals to be transmitted according to the first target transmit power through the first target antenna. In this way, the user terminal can reduce the reduction value of the current transmit power of the first radio frequency signal (for example, the current transmit power of the first radio frequency signal may not be reduced), thereby increasing the current total transmit power of the user terminal (for example, the user terminal is currently used for The sum of the transmit power used to transmit the first radio frequency signal and the second radio frequency signal), thereby improving the uplink performance of the user terminal.
