Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, in an embodiment, a power adjustment method is provided and applied to a terminal device, where the terminal device includes:
step 101: and receiving a power adjustment instruction sent by the base station, wherein the power adjustment instruction comprises a target transmitting power.
In the communication process between the terminal device and the base station, the base station may require the terminal device to adjust its transmission power due to various factors (e.g., movement of the terminal device or human factors) that may cause the transmission power of the terminal device to change. That is, the base station may send a power adjustment instruction carrying the target transmission power to the terminal device, so as to require the terminal device to adjust the power based on the target transmission power, so as to meet the requirements of the base station.
Step 102: and under the condition that the target transmitting power belongs to the preset overlapping power range, acquiring first transmitting power corresponding to the target transmitting power within the preset overlapping power range.
In the terminal device, a preset overlap power range (which can be understood as a preset overlap power interval) is stored in advance, after the target transmission power is obtained, whether the target transmission power is within the preset overlap power range can be judged, and if the target transmission power is within the preset overlap power range, a first transmission power corresponding to the target transmission power within the preset overlap power range can be obtained, that is, the first transmission power also belongs to the overlap power range and corresponds to the target transmission power, and the first transmission power can be understood as a transmission power matched with the target transmission power.
Step 103: and acquiring a first target gain level corresponding to the minimum power consumption of a radio frequency power amplifier of the terminal equipment under the first transmission power.
The first transmit power may correspond to different predetermined gain levels, which means that the first transmit power may be transmitted at different predetermined gain levels. The power consumption (i.e. the power consumption of the radio frequency power amplifier) corresponding to the first transmission power exists in each preset gain level, and after the first transmission power is obtained, a first target gain level corresponding to the minimum power consumption in the first transmission power can be obtained.
Step 104: and adjusting the current gain level of the radio frequency power amplifier to a first target gain level, and adjusting the transmission power of the radio frequency power amplifier to a first transmission power.
The first target gain level is the gain level with the minimum power consumption corresponding to the first transmission power, in order to reduce the power consumption of the radio frequency power amplifier, the current gain level of the radio frequency power amplifier is adjusted to the first target gain level, and the transmission power of the radio frequency power amplifier is adjusted to the first transmission power corresponding to the target transmission power required by the base station, so that the communication quality is improved.
In the power adjustment method of the embodiment of the invention, if the target transmission power belongs to the preset overlapping power range, the first transmission power corresponding to the target transmission power in the preset overlapping power range is obtained, the first target gain level corresponding to the minimum power consumption of the radio frequency power amplifier of the terminal equipment under the first transmission power is obtained, the current gain level of the radio frequency power amplifier is adjusted to the first target gain level, and the transmission power of the radio frequency power amplifier is adjusted to the first transmission power. In the power adjustment process, under the condition that the target transmitting power belongs to the preset overlapping power range, the current gain level of the radio frequency power amplifier is adjusted to be the first target gain level corresponding to the minimum power consumption under the first transmitting power, so that the radio frequency power amplifier works in the minimum power consumption state under the first transmitting power, the power consumption of the radio frequency amplifier can be reduced, the power consumption of the terminal equipment is reduced, the standby time of the terminal equipment is prolonged, the use time of the terminal equipment can be prolonged, convenience is brought to users, and the user experience is improved.
In the embodiment of the present invention, the terminal Device may include, but is not limited to, a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
In one embodiment, adjusting the current gain level of the radio frequency power amplifier to the first target gain level may include: and under the condition that the current gain level of the radio frequency power amplifier is the same as the first target gain level, adjusting the current gain level of the radio frequency power amplifier to the first target gain level.
That is, if the current gain level of the rf power amplifier is not adjusted to the first target gain level, it indicates that the current gain level of the rf power amplifier is not the gain level with the minimum power consumption under the first transmit power, and in order to reduce the power consumption of the rf power amplifier, the current gain level of the rf power amplifier may be adjusted to the first target gain level. If the adjustment of the current gain level of the radio frequency power amplifier is the same as the first target gain level, the current gain level of the radio frequency power amplifier is the gain level with the minimum power consumption under the first transmission power, the current gain level of the radio frequency power amplifier does not need to be adjusted, and the current gain level of the radio frequency power amplifier is maintained.
In one embodiment, obtaining a target gain level corresponding to minimum power consumption of a radio frequency power amplifier in a terminal device under a first transmission power includes: acquiring at least two target power consumptions corresponding to at least two preset gain levels of a radio frequency power amplifier in terminal equipment under first transmission power, wherein the preset gain levels correspond to the target power consumptions one to one; comparing the at least two target power consumptions to obtain a first target gain level corresponding to the minimum power consumption of the at least two target power consumptions.
The radio frequency power amplifier in the terminal equipment can work at different gain levels, and the different gain levels correspond to different gains. In this embodiment, the rf power amplifier may correspond to at least two preset gain levels, that is, N preset gain levels, where N is an integer greater than 1. Each preset gain level can have a plurality of corresponding transmission powers, and the radio frequency power amplifier can output the corresponding transmission powers under different preset gain levels. Because the first transmission power is the transmission power within the preset overlapping power range, the first transmission power can correspond to at least two target gain levels in the N preset gain levels, and thus, at least two target power consumptions corresponding to the at least two target gain levels under the first transmission power can be obtained. The target gain levels correspond to the target power consumptions one by one, that is, each of the at least two target gain levels corresponding to the first transmission power corresponds to one target power consumption, that is, the first transmission power corresponds to at least two target power consumptions. Then, the at least two target power consumptions are compared, and a first target gain level corresponding to the minimum power consumption in the at least two target power consumptions is determined. After the at least two target power consumptions are obtained, the at least two target power consumptions can be compared to obtain the minimum power consumption, and therefore the first target gain grade of the minimum power consumption drinking can be obtained and used as the basis for subsequent gain grade adjustment. Subsequently, the current gain level of the radio frequency power amplifier is adjusted to a first target gain level, and the transmission power of the radio frequency power amplifier is adjusted to a first transmission power.
The method comprises the steps of obtaining the current gain level of a radio frequency power amplifier, adjusting the current gain level of the radio frequency power amplifier to be a first target gain level, adjusting the transmitting power of the radio frequency power amplifier to be a first transmitting power, enabling the radio frequency power amplifier to output the first transmitting power under the first target gain level with the minimum power consumption, and reducing the power consumption of the radio frequency power amplifier, so that the power consumption of terminal equipment can be reduced, and the power consumption of the terminal equipment can be reduced.
In one embodiment, obtaining a first transmit power corresponding to a target transmit power within a preset overlap power range includes: and determining a first transmitting power with the minimum difference value between the target transmitting power and the preset overlapping power range based on a first corresponding relation corresponding to different preset gain levels in at least two preset gain levels.
The first corresponding relation is a preset corresponding relation between transmitting power and power consumption, and the at least two preset gain levels comprise at least two target gain levels.
In this embodiment, the radio frequency power amplifier of the terminal device may correspond to at least two preset gain levels, that is, the radio frequency power amplifier may operate in any one gain level of the at least two preset gain levels. The at least two target gain levels corresponding to the first transmit power are at least two of at least two preset gain levels. Each preset gain level corresponds to a preset corresponding relation between transmitting power and power consumption, the preset corresponding relation between the transmitting power and the power consumption comprises preset transmitting power and power consumption corresponding to the preset transmitting power, and the number of the preset transmitting power in one first corresponding relation is multiple. After the target transmitting power within the preset overlapping power range is obtained, the preset transmitting power with the minimum difference value between the target transmitting power and the preset transmitting power in the corresponding relation between the preset transmitting power and the power consumption corresponding to the preset gain level can be used as the first transmitting power, so that the target transmitting power required by the base station is ensured to be closer, and the accuracy of output is improved. If the first transmission power is the same as the target transmission power, it indicates that the preset transmission power which is the same as the target transmission power required by the base station exists in the corresponding relation between the preset transmission power corresponding to the preset gain level and the power consumption, and thus, the target transmission power required by the base station can be output.
In one embodiment, the preset overlap power range includes an overlap range corresponding to each two of the at least two preset gain levels. The upper limit of the overlapping range is the maximum same preset transmitting power in the corresponding relationship between the two corresponding preset transmitting powers and the power consumption, and the lower limit of the overlapping range is the minimum same preset transmitting power in the corresponding relationship between the two corresponding preset transmitting powers and the power consumption.
Each preset gain level corresponds to a first corresponding relation, each first corresponding relation relates to the preset transmitting power and the power corresponding to the preset transmitting power, if frequency range overlapping can exist between the first corresponding relations of any two preset gain levels, and the overlapping range is empty, the overlapping range is not overlapped. The preset overlap power range includes a corresponding overlap range of every two preset gain levels of the at least two preset gain levels. For example, there are three preset gain levels, i.e., a first preset gain level, a second preset gain level and a third preset gain level, an overlap range f1 of the first preset gain level and the third preset gain level is [ P1, P3], the first preset gain level and the second preset gain level f2 are [ P4, P8], the overlap range f3 of the second preset gain level and the third preset gain level is [ P9, P12], and thus, the preset overlap power range includes overlap ranges f1, f2 and f 3.
It is understood that the overlapping ranges of the two preset gain levels are determined according to the preset transmission powers in the respectively corresponding first corresponding relations. Because the first corresponding relation of each preset gain level relates to the preset transmitting power, the same preset transmitting power in the first corresponding relation of the two preset gain levels can be found out, a closed interval from the minimum same preset transmitting power to the maximum same preset transmitting power is used as an overlapping range of the two preset gain levels, and the preset transmitting power in the overlapping range in the first corresponding relation of one preset gain level in the two preset gain levels is in one-to-one correspondence with the preset transmitting power in the overlapping range in the first corresponding relation of the other preset gain level in the two preset gain levels and is the same. For example, the overlapping range of the first preset gain level and the second preset gain level is [ P4, P8], the preset transmission powers between [ P4, P8] in the first corresponding relationship of the first preset gain level are P5, P6 and P7, and the preset transmission powers between [ P4, P8] in the first corresponding relationship of the second preset gain level are also P5, P6 and P7, which are corresponding and the same. Therefore, the preset overlapping power range and the preset transmitting power in the corresponding relation between the preset transmitting power corresponding to the preset gain level and the power consumption can be related, and the accuracy of the preset overlapping power range can be improved.
In an example, taking an example that the radio frequency power amplifier corresponds to two preset gain levels, where the two preset gains include a first preset gain level and a second preset gain level, as shown in table 1, the two preset gains are a table of correspondence between preset transmission power and power consumption corresponding to the radio frequency power amplifier in the terminal device. Namely, a comparison table of each preset transmitting power and power consumption of the radio frequency power amplifier at a first preset gain level and a second preset gain level is established in the terminal equipment in advance. Wherein STATE1 represents a first preset gain level, which is a high gain level, STATE0 represents a second preset gain level, which is a low gain level, and the gain corresponding to the first preset gain level is greater than the gain corresponding to the second preset gain level, that is, the amplification factor of the terminal device is greater than the second preset gain level when the terminal device is at the first preset gain level. In table 1, the STATE1 output power indicates the preset transmission power (i.e., the preset output power) at the first preset gain level, the STATE0 output power indicates the preset transmission power at the second preset gain level, the STATE1 power consumption indicates the power consumption corresponding to the preset transmission power at the first preset gain level, and the STATE0 power consumption indicates the power consumption corresponding to the preset transmission power at the second preset gain level. Among the corresponding preset transmitting powers in the two preset gain levels, P4, P5, P6, P7 and P8 are the same preset transmitting power, P4 is the minimum same preset transmitting power, P8 is the maximum same preset transmitting power, and P5, P6 and P7 are in one-to-one correspondence in the first corresponding relationship corresponding to the two preset gain levels and are the same. The two predetermined gain levels can be set to P4, P8, and thus the predetermined overlap power range can be P4, P8. Under the condition of the same power, the corresponding power consumptions are not only different, such as the size of P4 in the STATE1 STATE and the size of P4 in the STATE0 STATE are the same, but also different from I1-4 and I0-1.
TABLE 1
The terminal equipment can detect whether the base station requires the terminal equipment to carry out power adjustment, if the base station does not require the terminal equipment to adjust the power, the terminal maintains the current STATE, if the terminal equipment is required to adjust the power, a power adjustment instruction carrying target transmission power is sent to the terminal equipment, if the terminal equipment obtains a target transmission power size bit P required to be transmitted by the base station and required by the terminal equipment, whether the P is in a preset overlapping power range [ P4, P8] corresponding to the table 1 is judged, if the P is not in the preset overlapping power range [ P4, P8], the terminal equipment responds to the power adjustment instruction of the base station, second transmission power corresponding to the P is determined from the table 1, for example, the second transmission power is P12, if the current gain level of the radio frequency power amplifier is in STATE0 and the transmission power can be in P12, the transmission power of the radio frequency power amplifier is adjusted to be the second transmission power P12 corresponding to the P, and maintains the operating STATE of the current STATE0 gain level.
If the base station requires the target transmission power P transmitted by the rf power amplifier to be within the preset overlap power range [ P4, P8], for example, the base station requires the target transmission power P4 transmitted by the terminal device, and at this time, the P4 is within the preset overlap power range, the power consumption I1-4 (corresponding to STATE1) and the power consumption I0-1 (corresponding to STATE0) respectively corresponding to two gain levels STATE1 and STATE0 of the rf power amplifier under the same preset transmission power (P4) are detected. Then, comparing the sizes of I1-4 and I0-1, if I1-4 is greater than I0-1, if the current gain level of the radio frequency power amplifier is STATE1, adjusting the current gain level of the radio frequency power amplifier to STATE0, if the current gain level of the radio frequency power amplifier is STATE0, maintaining the current gain level unchanged, and adjusting the transmission power of the radio frequency power amplifier to P4. If I1-4 is smaller than I0-1, if the current gain level of the radio frequency power amplifier is STATE0, the current gain level of the radio frequency power amplifier is adjusted to STATE1, if the current gain level of the radio frequency power amplifier is STATE1, the current gain level is maintained unchanged, and then the transmitting power of the radio frequency power amplifier is adjusted to P4 so as to meet normal communication between the terminal equipment and the base station.
By establishing the corresponding relation between the preset transmitting power and the power consumption of the radio frequency power amplifier in the working states with different gain levels, the radio frequency power amplifier is ensured to work in a low power consumption state no matter the terminal equipment is transited to a weak signal area from a strong signal area or transited to the strong signal area from the weak signal area, the power consumption of the terminal equipment is reduced, the service life of the whole machine is prolonged, and the user experience is improved.
In one embodiment, adjusting the transmit power of the radio frequency power amplifier to a first transmit power comprises: and adjusting the input power of the radio frequency power amplifier to enable the transmission power of the radio frequency power amplifier to be the first transmission power.
The output power of the radio frequency power amplifier, namely the transmission power, is determined by the input power and the gain, and after the current gain level of the radio frequency power amplifier is adjusted to the first target gain level, the accurate adjustment of the transmission power can be realized by adjusting the input power.
In one embodiment, the method further comprises: under the condition that the target transmitting power does not belong to the preset overlapping power range, acquiring second transmitting power corresponding to the target transmitting power; acquiring a second target gain level corresponding to the radio frequency power amplifier in the terminal equipment under a second transmitting power; under the condition that the current gain level of the radio frequency power amplifier is different from the second target gain level, adjusting the current gain level of the radio frequency power amplifier to the second target gain level, and adjusting the transmission power of the radio frequency power amplifier to the second transmission power; and under the condition that the current gain level of the radio frequency power amplifier is the same as the second target gain level, adjusting the transmission power of the radio frequency power amplifier to be second transmission power.

step 205: and under the condition that the current gain level of the radio frequency power amplifier is the same as the second target gain level, adjusting the transmission power of the radio frequency power amplifier to be second transmission power.
If the target transmitting power does not belong to the preset overlapping power range, the working state without two or more gain levels can realize the output with the transmitting power matched with the target transmitting power. At this time, the second transmitting power corresponding to the target transmitting power can be obtained, the second target gain level to which the second transmitting power belongs is determined, whether the current gain level of the radio frequency power amplifier is the second target gain level or not is judged, if yes, the current gain level of the radio frequency power amplifier is in a level needing to be switched, the current gain level of the radio frequency power amplifier is maintained unchanged, and the transmitting power of the radio frequency power amplifier is adjusted to the second transmitting power immediately. Otherwise, after the current gain level of the radio frequency power amplifier needs to be adjusted to the second target gain level, the transmitting power of the radio frequency power amplifier is adjusted to the second transmitting power, and the radio frequency power amplifier is ensured to output with the second transmitting power.
