Technical Field
The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, and a user terminal for improving uplink performance.
Background
The radio frequency absorption rate (SAR) is the radio frequency energy absorbed by a human body per unit weight in a unit time. Currently, SAR is widely used to measure whether the influence of electromagnetic radiation of a user terminal on a human body meets a standard. For example, the FCC certification standards promulgated by the Federal Communications Commission (FCC) in the united states stipulate SAR values of 1.6 watts per kilogram (i.e., 1.6 watts of radio frequency energy absorbed per kilogram of human tissue in 6 minutes). The SAR value is specified in european standards to be 2 watts/kg.
Currently, a user terminal detects the distance between each antenna and a human body through a sensor, and determines a current transmission power threshold corresponding to each antenna according to the distance and an SAR value (one of the SAR values specified by the above different standards can be selected), where the current transmission power threshold corresponding to each antenna is the maximum transmission power required by the antenna to meet the SAR value of the radio frequency capacity absorption ratio at the current distance between the antenna and the human body. Subsequently, when the ue detects that the transmission power of the radio frequency transmitted on a certain antenna exceeds the current transmission power threshold of the antenna, the transmission power of the radio frequency needs to be reduced. Therefore, the total transmission power of the user terminal is ensured to meet the transmission power corresponding to the SAR value specified in the standard.
However, the uplink performance of the ue is affected after the ue reduces the transmit power.

According to the method for improving the uplink performance, the user terminal obtains the first transmission power corresponding to one or more first radio frequency signals to be transmitted. When the first transmission power is greater than a current transmission power threshold of a first antenna to which the first radio-frequency signal currently belongs, and at least one antenna with the current transmission power threshold greater than the current transmission power threshold of the first antenna exists in at least one antenna except the first antenna in the at least two antennas, the user terminal determines a first target antenna with the first current transmission power threshold being closest to the first transmission power in the forward direction from the at least one antenna with the current transmission power threshold greater than the current transmission power threshold of the first antenna.

Detailed Description
The embodiment of the present application provides a method for improving uplink performance, which may be applied to a user terminal in a communication network, and in particular, may be applied to a user terminal in a non-independent (NSA) networking architecture based on dynamic shared power. Fig. 1 is an architecture diagram of a communication network provided in an embodiment of the present application, and as shown in fig. 1, the communication network includes an access network device and a user terminal. Wherein, the access network equipment and the user terminal can communicate by wireless technology.
It should be noted that the communication network may be a communication network supporting a fourth generation (4G) access technology, for example, a Long Term Evolution (LTE) access technology; alternatively, the communication network may be a communication network supporting a fifth generation (5G) access technology, for example, a New Radio (NR) access technology; alternatively, the communication network may be a communication network supporting a third Generation (3G) access technology, such as universal mobile telecommunications network (UMTS) access technology, third Generation Partnership Project (3rd Generation Partnership Project, 3 GPP); or the communication network may also be a communication network of a second generation (2G) access technology, such as a global system for mobile communications (GSM) access technology; alternatively, the communication network may also be a communication network supporting a plurality of wireless technologies, such as a communication network supporting LTE technology and NR technology. In addition, the communication network may also be adapted for future oriented communication technologies. The access network device in fig. 1 may be a device for supporting a terminal to access a communication system at an access network side, and may be, for example, a Base Transceiver Station (BTS) and a Base Station Controller (BSC) in a 2G access technology communication system, a node b (node b) and a Radio Network Controller (RNC) in a 3G access technology communication system, an evolved node b (eNB) in a 4G access technology communication system, a next generation base station (next generation node b, gNB) in a 5G access technology communication system, a Transmission Reception Point (TRP), a relay node (relay node), an Access Point (AP), and the like. A user terminal may be a device that provides voice or data connectivity to a user, and may also be referred to as User Equipment (UE), mobile station (mobile station), subscriber unit (subscriber unit), station (station), Terminal Equipment (TE), etc. But may also be a cellular telephone (cellular phone), Personal Digital Assistant (PDA), wireless modem (modem), handheld device (hand-held), laptop computer (laptop computer), cordless telephone (cordless phone), Wireless Local Loop (WLL) station, tablet (pad), etc. With the development of wireless communication technology, all devices that can access a communication system, can communicate with a network side of the communication system, or communicate with other objects through the communication system may be terminals in the embodiments of the present application, such as terminals and automobiles in intelligent transportation, home devices in smart homes, power meter reading instruments in smart grid, voltage monitoring instruments, environment monitoring instruments, video monitoring instruments in smart security networks, cash registers, and so on.
The user terminal comprises at least two antennas. The present embodiment is described by taking an example in which the user terminal includes a first antenna and a second antenna, and the other cases are similar to the above. The user equipment can transmit a first radio frequency signal to the access network equipment through the first antenna and transmit a second radio frequency signal to the access network equipment through the second antenna; the second radio frequency signal may also be transmitted to the access network device through the first antenna, the first radio frequency signal may also be transmitted to the access network device through the second antenna, the first radio frequency signal and the second radio frequency signal may also be transmitted to the access network device through the first antenna, and the first radio frequency signal and the second radio frequency signal may also be transmitted to the access network device through the second antenna, which is not limited in the embodiment of the present application.
It should be noted that, in some embodiments, the user terminal is a terminal supporting the NSA networking architecture and having a dynamic power sharing capability. The first radio frequency signal belongs to a signal of a primary cell under an NSA networking architecture where the user terminal is located. The second radio frequency signal belongs to a signal of a secondary cell under the NSA networking architecture where the user terminal is located.
In some embodiments, the ue may be a ue supporting an NSA networking architecture and having a dynamic power sharing capability, and when the LTE network is used as a primary cell under the NSA networking architecture where the ue is located, and the NR network is used as a secondary cell under the NSA networking architecture where the ue is located, the first radio frequency signal is an LTE signal, and the second radio frequency signal is an NR signal. The first and second radio frequency signals referred to herein may each comprise one or more signals.
In the dynamic power sharing based NSA networking, the access network device may send control signaling to the user terminal through a downlink control channel. The control signaling includes the transmission power of the first radio frequency signal and the transmission power of the second radio frequency signal in each slot (slot) of the user terminal.
For example, fig. 2A is a schematic diagram of dynamic power sharing provided in an embodiment of the present application. As shown in fig. 2A, the maximum transmission power of the user terminal (i.e., the maximum transmission power of the signal that can be transmitted by the user terminal's own capability) is 25 dbm. In the first time slot, the transmitting power of the first radio frequency signal is 15dbm, and the transmitting power of the second radio frequency signal is 10 dbm; in the second time slot, the transmitting power of the first radio frequency signal is 10dbm, and the transmitting power of the second radio frequency signal is 15 dbm; in the third time slot, the transmitting power of the first radio frequency signal is 20dbm, and the transmitting power of the second radio frequency signal is 5 dbm; in the fourth time slot, the transmission power of the first radio frequency signal is 15dbm, and the transmission power of the second radio frequency signal is 10 dbm.
It should be noted that, in the NSA networking based on dynamic shared power, the access network device (e.g., the base station) may also allocate transmission power for the first radio frequency signal and the second radio frequency signal according to the current network environment. For example, control signaling is carried in a first radio frequency signal (e.g., an LTE signal), and the access network device may allocate the remaining transmit power to a second radio frequency signal (e.g., an NR signal) based on preferentially satisfying the transmit power of the first radio frequency signal. For example, the maximum transmission power of the user terminal is 25dbm, when the user terminal is far away from the access network device, the access network device preferentially satisfies the transmission power of the first radio frequency signal, the transmission power allocated to the first radio frequency signal is 24dbm, and the transmission power allocated to the second radio frequency signal is 1 dbm; when the distance between the user terminal and the access network equipment is short, the access network equipment preferentially meets the transmitting power of the first radio frequency signal, the transmitting power distributed to the first radio frequency signal is 5dbm, and the transmitting power distributed to the second radio frequency signal is 20 dbm.
The user terminal also comprises 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 for continuously detecting a first distance between the first antenna and the human body and a second distance between the second antenna and the human body according to a preset detection period, and respectively sending the detected first distance and second distance to the first modem and the second modem. And the first modem is used for determining a first current transmission power threshold corresponding to the first antenna according to the first distance and the SAR. Similarly, the second modem is configured to determine a 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 transmission power of the first radio frequency signal is greater than the first current transmission power threshold, the transmission power of the first radio frequency signal may be reduced. Similarly, when the second modem detects that the current transmission power of the second radio frequency signal is greater than the second current transmission power threshold, the transmission power of the second radio frequency signal may be reduced. Therefore, the transmission power of the user terminal can be ensured to meet the transmission power corresponding to the SAR specified in the standard. But the current total transmission power of the ue (e.g., the sum of the transmission powers currently used by the ue to transmit the first rf signal and the second rf signal) is smaller than the maximum transmission power of the ue, thereby affecting the uplink performance of the ue. It should be noted that, both the first rf signal and the second rf signal may correspond to only one same modem, and the embodiment of the present application takes the example that the first rf signal corresponds to the first modem and the second rf signal corresponds to the second modem, and the other cases are similar to them.
For example, fig. 2B is a schematic diagram of dynamic power sharing after SAR reduction according to an embodiment of the present application, as shown in fig. 2B. In the first time slot, the current transmission power of the first radio frequency signal is 15dbm, the current transmission power of the second radio frequency signal is 10dbm, and it is assumed that in the first time slot, the first current transmission power threshold is 10dbm, the second current transmission power threshold is 15dbm, at this time, since the current transmission power of the first radio frequency signal is 15dbm and exceeds the first current transmission power threshold, the first modem reduces the current transmission power of the first radio frequency signal to 10dbm, so that the current total transmission power of the user terminal is reduced to 20dbm, the current total transmission power of the user terminal is less than the maximum transmission power of the user terminal, which is 25dbm, thereby causing power waste and affecting the uplink performance of the user terminal. As another example, in the third time slot, the current transmit power of the first radio frequency signal is 20dbm, the current transmit power of the second radio frequency signal is 5dbm, and it is assumed that in the third time slot, the first current transmit power threshold is 10dbm, and the second current transmit power threshold is 10 dbm. At this time, since the current transmission power of the first radio frequency signal is 20dbm, which exceeds the first current transmission power threshold, the first modem reduces the current transmission power of the first radio frequency signal to 10dbm, thereby reducing the current total transmission power of the user terminal to 15 dbm. The current total transmitting power of the user terminal is caused to be less than 25dbm of the maximum transmitting power of the user terminal, so that the uplink performance of the user terminal is influenced by the waste of power. As another example, in the fourth time slot, the current transmit power of the first radio frequency signal is 15dbm, the current transmit power of the second radio frequency signal is 10dbm, and it is assumed that in the fourth time slot, the first current transmit power threshold is 5dbm, and the second current transmit power threshold is 10 dbm. At this time, since the current transmission power of the first radio frequency signal is 15dbm, which exceeds the first current transmission power threshold, the first modem reduces the current transmission power of the first radio frequency signal to 5dbm, thereby reducing the current total transmission power of the user terminal to 15 dbm. The current total transmitting power of the user terminal is caused to be less than 25dbm of the maximum transmitting power of the user terminal, so that the uplink performance of the user terminal is influenced by the waste of power.
It should be noted that the sensor may also send the detected second distance to the first modem. Accordingly, the first modem may determine a second current transmit power threshold corresponding to the second antenna according to the second distance and the SAR. Similarly, the sensor may also send the detected first distance to the second modem. Accordingly, the second modem may determine a first current transmit power threshold corresponding to the first antenna based on the first distance and the SAR.
Some embodiments provided by the present application are described below in different scenarios:
1. for a scenario that the user terminal supports antenna switching and the first radio frequency signal is subjected to 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 of the first radio frequency signal, and the current transmit power threshold of at least one antenna is smaller 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 of the first radio frequency signal, and the current transmit power threshold of at least one antenna is greater than the current transmit power threshold of the first antenna, the user terminal may switch the first radio frequency signal to a first target antenna, and transmit the first radio frequency signal according to the first target transmit power. Wherein the first target transmit power is the lesser of the first transmit power and a first current transmit power threshold for the first target antenna.
(1) For the case that the user terminal transmits different radio frequency signals through different antennas
The first current transmit power threshold of the first target antenna may be a current transmit power threshold of an antenna closest to the first transmit power forward among the current transmit power thresholds of the antennas. Subsequently, if the first target transmission power is smaller than the first transmission power, the second rf signal may be boosted in power under the uplink limited condition, and may be transmitted at a second target transmission power on a second target antenna. The second target antenna is the antenna except the first target antenna, and the current transmission power threshold value is the largest; and if the first target transmission power is equal to the first transmission power, transmitting the second radio-frequency signal on a third target antenna with the third target transmission power, wherein the third target antenna is the current transmission power threshold of the antenna with the current transmission power threshold being closest to the second transmission power in the forward direction in other antennas except the first target antenna, and the third target transmission power is the smaller of the current transmission power threshold of the third target antenna and the second transmission power.
(2) For the case where the user terminal transmits different radio frequency signals through the same antenna
The current transmit power threshold for the first target antenna may be the largest of the current transmit power thresholds for the antennas. Subsequently, the second rf signal may also be switched to the first target antenna and transmitted at a fourth target transmit power. If the first target transmission power is smaller than the first transmission power, the second radio frequency signal can be boosted in power under the condition of uplink limitation. And the fourth target transmitting power is the power of the second radio frequency signal after being lifted. And if the first target transmitting power is equal to the first transmitting power, the fourth target transmitting power is the smaller of the current transmitting power threshold value of the first target antenna and the second transmitting power.
2. Antenna switching is supported for the user terminal, but the first radio frequency signal does not need to switch the scene of the antenna according to the situation.
If the current transmission power threshold of the first antenna to which the first radio frequency signal currently belongs is the antenna closest to the first transmission power in the forward direction in the current transmission power thresholds of the antennas, the user terminal may transmit the first radio frequency signal through the first antenna according to the first target transmission power. Wherein the first target transmit power is the lesser of the first transmit power and a current transmit power threshold for the first antenna.
(1) For the case that the user terminal transmits different radio frequency signals through different antennas, the following scheme may be adopted:
if the first target transmission power is lower than the first transmission power, the second rf signal may be boosted in power under the uplink limited condition, and may be transmitted at a second target transmission power on a second target antenna. The second target antenna is the antenna with the maximum current transmission power threshold among other antennas except the first antenna, and the second target transmission power is the power of the second radio-frequency signal after being lifted. And if the first target transmission power is equal to the first transmission power, transmitting the second radio frequency signal on a third target antenna at a third target transmission power. The third target antenna is the antenna with the current transmission power threshold value closest to the second transmission power in the forward direction in other antennas except the first antenna, and the third target transmission power is the smaller of the current transmission power threshold value of the third target antenna and the second transmission 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 at a fourth target transmit power on the first antenna. If the first target transmission power is smaller than the first transmission power, the second radio frequency signal can be boosted in power under the condition of uplink limitation. And the fourth target transmission power is the power of the second radio frequency signal after being lifted. And if the first target transmission power is equal to the first transmission power, the fourth target transmission power is the smaller of the current transmission power threshold value of the first antenna and the second transmission power.
3. For a scenario in which 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. Meanwhile, the user terminal may raise the transmission power of the second radio frequency signal under the condition that the second radio frequency signal is limited in uplink.
Some embodiments of the present application provide a method for improving uplink performance. As shown in fig. 3, the specific processing flow is as follows:
step 301, obtaining first transmission power corresponding to one or more first radio frequency signals to be transmitted.
The first transmission power is the transmission power allocated to the first radio frequency signal by the base station connected with the user terminal.
In implementation, in an implementation, the ue may continuously detect the first transmit power corresponding to the first rf signal according to a preset first detection period. The first transmit power may be a transmit power allocated to the first radio frequency signal by a base station to which the user equipment is connected.
Step 302, at least two antennas are used for the user equipment to transmit a first radio frequency signal and a second radio frequency signal through different antennas, and 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 one antenna with a current transmit power threshold greater than the current transmit power threshold of the first antenna exists in at least one of the at least two antennas except the first antenna, a first target antenna with the first current transmit power threshold closest to the first transmit power forward is determined from at least one antenna with the current transmit power threshold greater than the current transmit power threshold of the first antenna.
In implementation, the user terminal may continuously detect the distance between each antenna and the human body according to a preset second detection period. Then, for each antenna, the user terminal may determine a 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 first detection period. The embodiments of the present application are not limited.
For a case that the user terminal transmits different radio frequency signals through different antennas, when the user terminal detects that the first transmission power is greater than a current transmission power threshold of a first antenna to which the first radio frequency signal currently belongs, and antennas with current transmission power thresholds greater than the current transmission power threshold of the first antenna exist in antennas other than the first antenna, the user terminal may determine a first target antenna with the first current transmission power threshold closest to the first transmission power in the forward direction from antennas with current transmission power thresholds greater than the current transmission power threshold of the first antenna. The present embodiment provides two examples of determining a first target antenna by a user terminal, where the current transmit power thresholds of different antennas are different, specifically as follows:
for example, if there is at least one antenna with a current transmission power threshold greater than or equal to the current transmission power threshold of the first antenna, the first target antenna is the smallest current transmission power threshold among the current transmission power thresholds of the antennas with the current transmission power thresholds greater than or equal to the first transmission power.
In implementation, when the user terminal detects that the first transmission power is greater than the current transmission power threshold of the first antenna to which the first radio frequency signal currently belongs, and antennas with the current transmission power threshold greater than the current transmission power threshold of the first antenna exist in the antennas other than the first antenna, the user terminal may determine whether antennas with the current transmission power threshold greater than the current transmission power threshold of the first antenna exist in the antennas with the current transmission power greater than or equal to the first transmission power. And if so, the user terminal selects the antenna with the current transmission power threshold value larger than or equal to the minimum antenna in the current transmission power threshold values corresponding to all the antennas with the first transmission power as the first target antenna. Therefore, on the basis of ensuring that the user terminal transmits the first radio frequency signal according to the first transmission power, the antenna with the larger current transmission power threshold is reserved for the second radio frequency signal, and the transmission power of the second radio frequency signal can be further improved as much as possible under the condition that the uplink performance of the second radio frequency signal is limited.
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 first target antenna.
For example two, if the current transmit power threshold of each of the antennas with the at least one current transmit power threshold greater than the current transmit power threshold of the first antenna is less than the antenna with the first transmit power, the first target antenna is the largest of the current transmit power thresholds of each of the antennas with the at least one current transmit power threshold greater than the current transmit power threshold of the first antenna.
In implementation, when the user terminal detects that the first transmission power is greater than the current transmission power threshold of the first antenna to which the first radio frequency signal currently belongs, and antennas whose current transmission power thresholds are greater than the current transmission power threshold of the first antenna exist in the antennas other than the first antenna, the user terminal may determine whether the current transmission power thresholds of the antennas whose current transmission power thresholds are greater than the current transmission power threshold of the first antenna are all smaller than the antennas of the first transmission power. If the antennas are all smaller than the first transmission power, the user terminal may select, as the first target antenna, the antenna with the current transmission power threshold larger than the current transmission power threshold of the first antenna, which is the largest among the current transmission power thresholds of the antennas. In this way, the user terminal may transmit the first radio frequency signal according to the current transmission power threshold of the first target antenna, thereby increasing the transmission 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 first target antenna.
In some embodiments, when the first transmit power is less than a current transmit power threshold for a first antenna to which the first radio frequency signal currently belongs, and at least one antenna with current transmission power threshold smaller than the current transmission power threshold of the first antenna and larger than or equal to the first transmission power exists in at least one antenna except the first antenna in the at least two antennas, then there is at least one antenna from among the at least one antenna having a current transmit power threshold that is less than the current transmit power threshold for the first antenna and greater than or equal to the first transmit power, and determining a first target antenna with the first current transmission power threshold value being closest to the first transmission power in the forward direction, wherein the first target antenna is the minimum current transmission power threshold value of each antenna in at least one antenna with the current transmission power threshold value being smaller than the current transmission power threshold value of the first antenna and being larger than or equal to the first transmission power.
In implementation, for a case that the user terminal transmits different radio frequency signals through different antennas, when the first transmit power is less than a current transmit power threshold of a first antenna to which the first radio frequency signal currently belongs, and there are antennas, among antennas other than the first 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 may select, as the first target antenna, an antenna, from among the antennas 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, which antenna has a current transmit power threshold that is less than the current transmit power threshold of the first antenna and is greater than or equal to the first transmit power, is the smallest antenna among the current transmit power thresholds of the antennas whose current transmit power threshold is less than the current transmit power threshold of the first. Therefore, on the basis of ensuring that the user terminal transmits the first radio frequency signal according to the first transmission power, the antenna with the larger current transmission power threshold is reserved for the second radio frequency signal, and the transmission power of the second radio frequency signal can be further improved as much as possible under the condition that the uplink performance of the second radio frequency signal is limited.
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 first target antenna.
In some embodiments, the at least two antennas are used for the ue to transmit the first radio frequency signal and the second radio frequency signal through the same antenna, when at least one antenna with a current transmit power threshold greater than the current transmit power threshold of the first antenna exists in at least one of the at least two antennas except the first antenna, a first target antenna is determined from the antennas with the current transmit power thresholds greater than the current transmit power threshold of the first antenna, and the first current transmit power threshold of the first target antenna is the largest current transmit power threshold of each antenna among the antennas with the current transmit power thresholds greater than the current transmit power threshold of the first antenna.
In implementation, for a case that the user terminal transmits different radio frequency signals through the same antenna, when there are antennas whose current transmission power threshold is greater than the current transmission power threshold of the first antenna in antennas other than the first antenna, the user terminal may select, as the first target antenna, an antenna whose current transmission power threshold is greater than the current transmission power threshold of the first antenna from among the antennas whose current transmission power threshold is greater than the current transmission power threshold of the first antenna, the antenna whose current transmission power threshold is greater than the current transmission power threshold of the first antenna, which is the largest among current transmission power thresholds of the antennas.
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 first 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 first target antenna.
In some embodiments, when the current transmit power threshold of each of at least one of the at least two antennas other than the first antenna is less than or equal to the current transmit power threshold of the first antenna, the first target antenna is the first antenna, and the first current transmit power threshold of the first target antenna is the current transmit power threshold of the first antenna.
In an implementation, for a case where the ue transmits different radio frequency signals through different antennas or for a case where the ue transmits different radio frequency signals through the same antenna, when current transmit power thresholds of antennas other than the first antenna are all smaller than or equal to an antenna of the current transmit power threshold of the first antenna, the ue 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 first 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, then the user terminal selects the first antenna as the first target antenna.
Step 303, determining a first target transmit power according to the first transmit power and the first current transmit power threshold.
In implementation, after the user terminal determines a first target antenna for transmitting a first radio frequency signal, a first target transmission power corresponding to the first radio frequency signal may be determined according to the first transmission power and a first current transmission power threshold of the first target antenna.
In implementation, after the user terminal determines a first target antenna for transmitting a first radio frequency signal, a first target transmission power corresponding to the first radio frequency signal may be determined according to the first transmission power and a first current transmission power threshold of the first target antenna.
In some embodiments, the processing procedure for determining the first target transmission power by the user terminal according to the first transmission power and the first current transmission power threshold corresponding to the first target antenna is as follows:
step one, judging whether the first transmitting power is larger than a first current transmitting power threshold value.
In implementation, the ue may determine whether the first transmit power is greater than a 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 two. If the first transmit power is not greater than the first current transmit power threshold, the user terminal may perform step three.
And step two, taking the first current transmission power threshold value as a first target transmission power.
In implementation, if the first transmit power is greater than the first current transmit power threshold, which indicates that the user terminal needs to reduce the transmit power of the first radio frequency signal, 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 15 dbm. 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 15 dbm.
And step three, taking the first transmitting power as a first target transmitting power.
In an implementation, if the first transmit power is less than or equal to the first current transmit power threshold, which indicates that the user terminal does not need to decrease the transmit power of the first radio frequency signal, the user terminal may 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 15 dbm. The first transmit power is less than the first current transmit power threshold, which indicates 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, one or more first radio frequency signals to be transmitted are transmitted through a first target antenna according to a first target transmission power.
In implementation, after the user terminal determines a first target antenna and a first target transmission power corresponding to the first radio frequency signal, the user terminal may transmit the first radio frequency signal through the first target antenna according to the first target transmission power. Therefore, the user terminal can reduce the reduction value of the current transmitting power of the first radio frequency signal, so that the current total transmitting power of the user terminal is improved, and the uplink performance of the user terminal is improved.
In some embodiments, after the transmission power of the first transmission signal is reduced, the user terminal may select a suitable second target antenna to transmit the second radio frequency information. For the case that the user terminal transmits different radio frequency signals through different antennas and for the case that the user terminal transmits different radio frequency signals through the same antenna, the manner in which the user terminal selects the second target antenna is also different, which is specifically as follows:
in the first mode, for the case that the user terminal transmits different radio frequency signals through different antennas, the processing procedure is as follows:
step 110, if the first transmission power is greater than the first current transmission power threshold, obtaining second transmission power corresponding to one or more second radio frequency signals to be transmitted, and determining a second target antenna from at least one antenna except the first target antenna among the at least two antennas, wherein the second current transmission power threshold of the second target antenna is the largest current transmission power threshold of each antenna in the at least one antenna.
And the second transmitting power is the transmitting power distributed 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 first radio frequency signal reduces the transmit power. The user terminal may obtain a second transmission power corresponding to a second radio frequency signal to be transmitted. And the second transmitting power is the transmitting power distributed by the connected base station for the second radio frequency signal. Then, the user terminal may select, from the antennas other than the first target antenna, the antenna with the largest current transmit power threshold as the second target antenna. Thus, the user terminal can be ensured to raise the transmission power of the second transmission power as much as possible.
Step 120, if the second transmission power is smaller than the second current transmission power threshold, determining a 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.
And the sum of the second target transmission power and the first current transmission power threshold is less than or equal to the maximum transmission power.
In implementation, after the user terminal determines the second target antenna, it may further determine whether the second transmission power is smaller than a second current transmission power threshold corresponding to the second target antenna. If the second transmission power is smaller than the second current transmission power threshold, the user terminal may determine a 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. And the sum of the second target transmission power and the first current transmission power threshold is less than or equal to the maximum transmission power.
Optionally, the processing procedure of determining, by the user terminal, 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 is as follows:
and step 121, determining a transmission power increase value corresponding to the second radio frequency signal 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.
In implementation, the ue may determine the transmit power boost value corresponding to the second rf 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 ue.
Optionally, the processing procedure of the user terminal determining 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 is as follows:
step 1211, a second difference between the second current transmit power threshold and the second transmit power is determined.
In an implementation, the user terminal may calculate a second difference between the second current transmit power threshold and the second transmit power. The second difference is a maximum value which can be used for increasing the transmission power of the second radio-frequency signal on the basis that the user terminal meets the SAR requirement.
Step 1212, determining a second sum of the first current transmit power threshold and the second transmit power, and determining a third difference between the maximum transmit power corresponding to the ue and the second sum.
In an implementation, the user terminal may also determine a first current transmit power threshold and a second sum of the second transmit power. Wherein the second sum is the current total transmit power of the user terminal. The ue may then determine a third difference between the maximum transmit power corresponding to the ue (i.e., the maximum transmit power of the signal that the ue is capable of transmitting) and the second sum. The third difference is a maximum value that can be used to increase the transmission power of the second radio frequency signal on the basis that the user terminal satisfies the maximum transmission power.
After determining the second difference and the third difference, the ue 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 performs step 213. If the second difference is less than or equal to the third difference, the user terminal performs step 214.
Step 1213, the third difference is used as the transmit power boost value corresponding to the second rf signal.
In an implementation, if the second difference is greater than the third difference, the user terminal may use the third difference as a transmit power boost value corresponding to the second rf signal.
Step 1214, the second difference is used as the transmission power boost value corresponding to the second rf signal.
In an implementation, if the second difference is smaller than or equal to the third difference, the user terminal may use the second difference as a transmission power boost value corresponding to the second rf signal.
And step 122, taking the first sum of the second transmission power and the transmission power increasing value as a second target transmission power.
In implementation, after the user terminal determines the transmit power boost value corresponding to the second radio frequency signal, the first sum of the second transmit power and the transmit power boost value may be used as the second target transmit power of the second radio frequency signal.
Step 130, one or more second radio frequency signals to be transmitted are transmitted through the second target antenna according to the second target transmission power.
In implementation, after determining the second target transmission power of the second radio frequency signal, the user terminal may transmit the second radio frequency signal through the second target antenna according to the second target transmission power. Therefore, the user terminal can increase the transmission power of the second radio frequency signal as much as possible.
In the second mode, for the case that the user terminal transmits different radio frequency signals through the same antenna, the processing procedure is as follows:
step 210, if the first transmit power is greater than the first current transmit power threshold, obtaining a second transmit power corresponding to one or more second radio frequency signals to be transmitted, and determining a second target antenna from the at least two antennas, where the second current transmit power threshold of the second target antenna is the largest of the current transmit power thresholds of each of the at least two antennas.
And the second transmitting power is the transmitting power distributed 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 first radio frequency signal reduces the transmit power. The user terminal may obtain a second transmission power corresponding to a second radio frequency signal to be transmitted. And the second transmitting power is the transmitting power distributed 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. Thus, the user terminal can be ensured to raise the transmission power of the second transmission power as much as possible.
Step 220, if the second transmission power is smaller than the second current transmission power threshold, determining a 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.
And the sum of the second target transmission power and the first current transmission power threshold is less than or equal to the maximum transmission power.
In implementation, after the user terminal determines the second target antenna, it may further determine whether the second transmission power is smaller than a second current transmission power threshold corresponding to the second target antenna. If the second transmission power is smaller than the second current transmission power threshold, the user terminal may determine a 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. And the sum of the second target transmission power and the first current transmission power threshold is less than or equal to the maximum transmission power. The process of the user terminal determining 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 is similar to the step 120, and details are not repeated here.
Step 230, one or more second radio frequency signals to be transmitted are transmitted through the second target antenna according to the second target transmission power.
In implementation, after determining the second target transmission power of the second radio frequency signal, the user terminal may transmit the second radio frequency signal through the second target antenna according to the second target transmission power. Therefore, the user terminal can increase the transmission 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 downlink path loss of the second radio frequency signal, where the processing procedure is as follows:
step one, obtaining the current downlink path loss corresponding to the second radio frequency signal.
In implementation, the ue may continuously detect the current downlink path loss of the second rf signal according to a 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.
And step two, judging whether the current downlink path loss is larger than a prestored downlink path loss threshold value.
In an implementation, the user terminal may store a downlink loss threshold in advance. The downlink path loss threshold may be set empirically by a technician. After obtaining the current downlink path loss of the second radio frequency signal, the user terminal may determine whether the current downlink path loss value of the second radio frequency signal is greater than a pre-stored downlink path loss threshold. And if the current downlink path loss value of the second radio frequency signal is greater than the pre-stored downlink path loss threshold value, executing the third step. And 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 value, executing the step four.
And step three, determining a second target transmitting power according to the second current transmitting power threshold, the first current transmitting power threshold, the second transmitting power and the maximum transmitting 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 ue 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 ue. The process of determining the second target transmission power by the user terminal 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 is similar to the step 120, and is not repeated here.
And step four, taking the second transmitting power as second target transmitting power of the second radio frequency signals, and transmitting one or more second radio frequency signals to be transmitted through the second antenna according to the second target transmitting 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 transmission power is used as a second target transmission power of the second radio frequency signal, and one or more second radio frequency signals to be transmitted are transmitted through the second antenna according to the second target transmission power.
According to the method for improving the uplink performance, the user terminal obtains the first transmission power corresponding to one or more first radio frequency signals to be transmitted. When the first transmission power is greater than a current transmission power threshold of a first antenna to which the first radio-frequency signal currently belongs, and at least one antenna with the current transmission power threshold greater than the current transmission power threshold of the first antenna exists in at least one antenna except the first antenna in the at least two antennas, the user terminal determines a first target antenna with the first current transmission power threshold being closest to the first transmission power in the forward direction from the at least one antenna with the current transmission power threshold greater than the current transmission power threshold of the first antenna. Then, the user terminal determines a first target transmission power according to the first transmission power and the first current transmission power threshold. And then, the user terminal transmits one or more first radio frequency signals to be transmitted through the first target antenna according to the first target transmission power. In this way, the ue may reduce the reduction value of the current transmission power of the first rf signal (e.g., may not reduce the current transmission power of the first rf signal), so as to increase the current total transmission power of the ue (e.g., the sum of the transmission powers currently used by the ue to transmit the first rf signal and the second rf signal), thereby increasing the uplink performance of the ue.
