[0020] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more complete and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present disclosure. However, those skilled in the art will realize that the technical solutions of the present disclosure can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, well-known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0021] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0022] The flowcharts shown in the accompanying drawings are only exemplary illustrations and do not necessarily include all steps. For example, some steps can be further decomposed, while some steps can be combined or partially combined. Therefore, the actual execution order may change according to the actual situation. Additionally, all the following terms "first" and "second" are only for the purpose of distinction and should not be construed as limitations of the present disclosure.

[0023] For convenience of description, it should be noted in advance that the term "in the working state" as used in the present disclosure refers to the state of continuously transmitting data.

[0024] In the current antenna power back-off control scheme, regardless of whether the antenna is in the working state, each antenna in the antenna system of the terminal device adjusts its transmission power with the power back-off value when all antennas are in the working state.

[0025] In the case where the antenna system includes at least one first antenna in the working state and at least one second antenna in the non-working state, considering that the second antenna is not in the state of continuously transmitting data, if the power back-off value of the first antenna is still configured as the power back-off value when all antennas are in the working state, it will cause the problem that the communication performance of the first antenna cannot be fully utilized while meeting the compliance requirements.

[0026] In view of this, the present disclosure provides a new antenna power adjustment scheme.

[0027] Reference Figure 1 , the terminal device 10 may be various electronic devices configured with multiple antennas and capable of corresponding communication capabilities, including but not limited to smart phones, tablet computers, smart wearable devices, etc.

[0028] The terminal device 10 may include an antenna system, and the antenna system may include more than two antennas. For example, a cellular antenna 101, a WiFi antenna 102, a Bluetooth antenna 103, etc.

[0029] It should be noted that, on the one hand, in the exemplary embodiments of the present disclosure, the same antenna name may correspond to multiple types of antennas. For example, although they are both WiFi antennas, 2.4G WiFi and 5G WiFi can be regarded as two different types of antennas; on the other hand, Figure 1 only the antenna situation included in the terminal device 10 is exemplarily shown. The terminal device 10 may also include only any two of the cellular antenna 101, the WiFi antenna 102, and the Bluetooth antenna 103, or may also include other types of antennas. The present disclosure does not limit the number of antennas equipped on the terminal device 10.

[0030] In one embodiment, the antenna system may be composed of a cellular antenna and a WiFi antenna. In another embodiment, the antenna system may include a cellular antenna, a WiFi antenna, and a Bluetooth antenna. Among them, the WiFi antenna may include a 2.4G WiFi antenna and / or a 5G WiFi antenna.

[0031] In addition, the antenna system may further include more than two MHB (Middle High Band) antennas. When a user holds some of the antennas, resulting in a performance decline and inability to support MHB signal transmission and / or reception, other non-held MHB antennas are used to support MHB signal transmission and / or reception.

[0032] Taking the scenario where the antenna system of the terminal device 10 includes the cellular antenna 101 and the WiFi antenna 102 as an example, some embodiments of the present disclosure will be described below.

[0033] In some embodiments of the present disclosure, in order to make the Specific Absorption Rate (SAR) meet the compliance requirements, when only the cellular antenna 101 is in the working state, a single cellular back-off value is called, that is, the power back-off value of the cellular antenna 101 when only the cellular antenna 101 is in the working state. When only the WiFi antenna 102 is in the working state, a single WiFi back-off value is called, that is, the power back-off value of the WiFi antenna 102 when only the WiFi antenna 102 is in the working state. When the cellular antenna 101 and the WiFi antenna 102 are both in the working state, for the cellular antenna 101, a combined power back-off value of the cellular antenna is called, that is, the power back-off value of the cellular antenna 101 when all antennas in the antenna system are in the working state; for the WiFi antenna 102, a combined power back-off value of the WiFi antenna is called, that is, the power back-off value of the WiFi antenna 102 when all antennas in the antenna system are in the working state.

[0034] The combined power back-off value is usually greater than the back-off value corresponding to when the antenna is in the working state alone, that is, the combined power back-off value of the cellular antenna is usually greater than the single-cellular back-off value, and the combined power back-off value of the WiFi antenna is usually greater than the single-WiFi back-off value. That is to say, compared with the back-off value corresponding to when the antenna works alone, the combined power back-off value usually has more back-off, for example, 1 to 3 dB more back-off.

[0035] This combined back-off method does not consider whether both the cellular antenna 101 and the WiFi antenna 102 are in the working state. The configuration is simple and can ensure that the SAR value of the terminal device 10 meets the compliance requirements.

[0036] However, the cellular antenna 101 and the WiFi antenna 102 are not necessarily both in the working state. In this case, if the above combined back-off method is adopted, it may cause the problem of reduced transmission power and affect the communication experience. For example, when the cellular antenna 101 is in the non-working state, such as the standby state (IDLE state) of connecting to the network but not continuously transmitting data, if the combined power back-off value of the WiFi antenna is still used to adjust the transmission power of the WiFi antenna 102 under the condition of meeting the compliance requirements, it will result in a relatively low transmission power of the WiFi antenna 102 and affect the actual WiFi usage experience.

[0037] To solve this problem, the terminal device 10 can identify the working states of the cellular antenna 101 and the WiFi antenna 102.

[0038] If the cellular antenna 101 is in the non-working state and the WiFi antenna 102 is in the working state, the single-WiFi back-off value can be called to adjust the transmission power of the WiFi antenna 102. In this case, the single-cellular back-off value can also be called to adjust the transmission power of the cellular antenna 101, or no back-off operation is performed on the cellular antenna 101.

[0039] If the WiFi antenna 102 is in the non-working state and the cellular antenna 101 is in the working state, the single-cellular back-off value can be called to adjust the transmission power of the cellular antenna 101. In addition, in this case, the single-WiFi back-off value can also be called to adjust the transmission power of the WiFi antenna 102, or no back-off operation is performed on the WiFi antenna 102.

[0040] If both the cellular antenna 101 and the WiFi antenna 102 are in the working state, the corresponding combined power back-off value is called to adjust the transmission powers of the cellular antenna 101 and the WiFi antenna 102 respectively.

[0041] Thus, under the condition that the SAR value meets the compliance requirements, the terminal device 10 can enable the cellular antenna 101 or the WiFi antenna 102 to have a relatively high transmission power, which helps to improve the user's communication experience.

[0060] The units described in the embodiments of the present disclosure may be implemented in software or in hardware, and the described units may also be provided in a processor. Among them, the names of these units do not constitute a limitation to the unit itself in some cases.

[0061] The antenna power adjustment method according to the embodiments of the present disclosure can be applied to a terminal device. The terminal device includes an antenna system, and the antenna system includes at least one first antenna in a working state and at least one second antenna in a non-working state.

[0062] The antenna power adjustment method may include: reducing the transmission power of the first antenna to a first transmission power. Wherein, the absolute value of the difference between the transmission power of the first antenna and the first transmission power is a first power back-off value, and the first power back-off value is less than the combined power back-off value of the first antenna. The combined power back-off value of the first antenna is the power back-off value of the first antenna when all antennas in the antenna system are in a working state.

[0063] It can be understood that the terminal device can control the transmission power of the first antenna to be reduced by the first power back-off value, and the first power back-off value is the amplitude by which the transmission power of the first antenna is reduced.

[0064] Figure 3 Schematically shows a flowchart of the antenna power adjustment method according to the exemplary embodiments of the present disclosure. Refer to Figure 3 , the antenna power adjustment method may include the following steps:

[0065] S32. Obtain the first power back-off value; wherein, the first power back-off value is less than the combined power back-off value of the first antenna, and the combined power back-off value of the first antenna is the power back-off value of the first antenna when all antennas in the antenna system are in a working state.

[0066] In the exemplary embodiments of the present disclosure, the states of the antennas in the antenna system can be divided into: a transmission state of continuously transmitting data, a standby state of being connected to the network without continuously transmitting data, and a disconnected state of not being connected to the network. Among them, the transmission state is a working state, the standby state and the disconnected state are non-working states, and the standby state can also be referred to as the IDLE state or the idle state.

[0067] It can be understood that generally, it can be determined whether an antenna is in a disconnected state by the amount of data transmitted and received or the connection identifier.

[0068] According to some embodiments of the present disclosure, when the antenna is connected to the network, it is possible to determine which antennas are in a working state and which antennas are in a non-working state based on the transmitted data of the antenna. Wherein, the transmitted data may include the data transmission amount and / or the data transmission time gap.

[0069] In an embodiment where the transmitted data includes the data transmission amount, if within a unit time, the data transmission amount of an antenna is greater than the transmission amount threshold, it can be determined that the antenna is in a working state; if the data transmission amount is not greater than the transmission amount threshold, it can be determined that the antenna is in a non-working state.

[0070] In an embodiment where the transmitted data includes a data transmission time gap, if it is determined that the data transmission time gap of an antenna is less than a transmission time threshold, it can be determined that the antenna is in an operating state; if the data transmission time gap is not less than the transmission time threshold, it can be determined that the antenna is in a non-operating state.

[0071] In an embodiment where the transmitted data includes a data transmission amount and a data transmission time gap, the comparison result between the data transmission amount of the antenna and a transmission amount threshold can be used as a first state determination result, and the comparison result between the data transmission time gap of the antenna and the transmission time threshold can be used as a second state determination result. Then, based on the first state determination result and the second state determination result, it can be determined whether the antenna is in an operating state or a non-operating state. For example, the first state determination result and the second state determination result can be combined in a weighted manner to determine the state of the antenna.

[0072] It should be noted that the present disclosure does not limit the specific values of the transmission amount threshold and the time threshold, which can be thresholds obtained by developers through experiments or analysis considering the SAR value of the terminal device.

[0073] According to some other embodiments of the present disclosure, for an antenna, the terminal device can be provided with a flag bit or identification information representing the antenna state, and the antenna state can be determined through the flag bit or the identification information.

[0074] In some embodiments, for a cellular antenna, if the terminal device is not in a call state and there is no continuous data upload, it is determined that the cellular antenna is in a standby state, that is, a non-operating state. For a WiFi antenna, if the terminal device is in a call state and there is no continuous data upload for the WiFi antenna, it is determined that the WiFi antenna is in a standby state, that is, a non-operating state.

[0075] In an exemplary embodiment of the present disclosure, based on the above process, at least one first antenna in an operating state and at least one second antenna in a non-operating state can be determined from the antenna system equipped in the terminal device.

[0076] For each first antenna, the terminal device can obtain a corresponding first power back-off value to control the transmission power to be reduced to a first transmission power.

[0077] According to some embodiments of the present disclosure, a first power back-off value can be determined based on the antenna combination obtained from the first antenna. The antenna combination can be used to characterize the combination mode of the types of the first antenna, that is, the combination of antennas that are simultaneously in the working state in the antenna system. For example, "cellular + 2.4G WiFi" is an antenna combination, "cellular + 2.4G WiFi + 5GWiFi" is another antenna combination, and "cellular + Bluetooth" is also an antenna combination. In addition, only one antenna can also be an antenna combination. For example, a single "cellular" can also be used as an antenna combination.

[0078] First, the terminal device can determine the antenna combination obtained from the first antenna.

[0079] Next, the terminal device can determine a back-off value mapping table corresponding to the antenna combination based on the antenna combination, and use the back-off value mapping table to find out the power back-off value of the first antenna as the first power back-off value. The back-off value mapping table contains the mapping relationship between the antenna and the power back-off value.

[0080] Specifically, each antenna combination is configured with an identifier, and the identifier has a one-to-one correspondence with the back-off value mapping table. Thus, the corresponding back-off value mapping table can be determined through the identifier of the antenna combination. For example, if the identifier of "cellular + 2.4GWiFi" is pre-recorded as z, and the back-off value mapping table corresponding to the identifier z is Table Z. In this case, if the antenna combination determined currently is "cellular + 2.4G WiFi", the back-off value mapping table Z corresponding to "cellular + 2.4G WiFi" can be determined by means of the identifier z.

[0081] In the exemplary embodiment of the present disclosure, the back-off value mapping table stores the mapping relationship between the antenna and the back-off value. Thus, after determining the back-off value mapping table corresponding to the antenna combination, the power back-off value of each antenna in the antenna combination can be found out by using the back-off value mapping table.

[0082] The power back-off value of each antenna under different antenna combinations can be determined in advance. Specifically, the electromagnetic wave absorption ratio test values of each antenna in the antenna system when they are respectively in the working state can be determined in advance, and then, in combination with the electromagnetic wave absorption ratio test values of each antenna when they are respectively in the working state and an electromagnetic wave absorption ratio threshold value, the power back-off values of each antenna under different antenna combinations can be determined respectively. The electromagnetic wave absorption ratio threshold value can be obtained based on compliance requirements.

[0083] Taking the example that the antenna combination only includes one antenna A, the threshold value of the specific absorption rate determined based on compliance requirements is C W / kg, and the measured value of the specific absorption rate of antenna A in the full-power transmission state is D W / kg. If D is less than or equal to C, power back-off may not be required. If D is greater than C, an intermediate power back-off value E can be determined, where E = 10lg(D / C). Subsequently, considering a certain measurement error, finally, in the case where the antenna combination only includes antenna A, the power back-off value E1 corresponding to antenna A can be obtained.

[0084] Taking the example that the antenna combination includes antenna A and antenna B, both antenna A and antenna B are in the working state. Compared with the case where only antenna A exists, when the antenna combination includes antenna A and antenna B, the SAR standard for one antenna is tightened, and the back-off value is relatively large.

[0085] The threshold value of the specific absorption rate can be divided according to the relative magnitudes of the measured values of the specific absorption rate when antenna A and antenna B are in the transmission state respectively. For example, the threshold value allocated to antenna A is C1 W / kg, and the threshold value allocated to antenna B is C2 W / kg. In this case, the intermediate power back-off value F of antenna A = 10lg(D / C1). Similarly, after considering the measurement error, finally, in the case where the antenna combination includes antenna A and antenna B, the power back-off value F1 of antenna A can be obtained. Similarly, the power back-off value F2 of antenna B in this case can be obtained.

[0086] For the same antenna A, different antenna combinations may correspond to different power back-off values. For example, the above-determined F1 is usually greater than E1.

[0087] Similarly, in the case where the antenna combination includes more than three antennas, the corresponding power back-off values can also be determined based on the above process, which will not be elaborated here.

[0088] Figure 4 The process of determining the power back-off value is schematically shown. Specifically, the antenna combination in the working state (i.e., the antenna combination of the first antenna) is determined from all the antennas in the antenna system equipped in the terminal device, and then the corresponding back-off value mapping table is determined according to this antenna combination. Next, according to this back-off value mapping table, the power back-off values of each antenna in the antenna combination can be determined.

[0089] In addition, in addition to pre-constructing the back-off value mapping table, in some other embodiments of the present disclosure, the first power back-off value can also be calculated in real time based on the above calculation process, and the calculation process will not be elaborated here.

[0090] According to some other embodiments of the present disclosure, first, the terminal device can determine the number of the first antennas. Next, the first power back-off value can be determined based on the number of the first antennas.

[0091] In these embodiments, the power back-off value may be related only to the number of the first antennas, that is, related to the number of antennas in the antenna system that are in the working state, and is independent of the type of the antennas. For example, for "cellular + 2.4G WiFi" and "cellular + 5G WiFi", for the cellular antennas, they are both in a scenario where two antennas are in the working state. Although there are differences between "2.4G WiFi" and "5G WiFi", the power back-off values corresponding to the cellular antennas are the same, that is, the first power back-off values are the same.

[0092] For another example, "cellular + 2.4G WiFi" and "cellular + 2.4G WiFi + 5G WiFi" include different numbers of antennas. Therefore, the determined power back-off values of the cellular antennas are also different.

[0093] In addition, the power back-off values of the first antennas under different numbers can be determined in advance. The specific method can be by manual setting or testing. The present disclosure does not limit the specific values of the power back-off values.

[0094] In addition, it should be noted that in view of the fact that the antenna system targeted by the present disclosure includes at least one first antenna in the working state and at least one second antenna in the non-working state, in order to fully exert the communication performance of the antennas, the first power back-off value is configured to be less than the combined power back-off value of the first antennas. Wherein, the combined power back-off value of the first antennas is the power back-off value of the first antennas when all the antennas in the antenna system are in the working state.

[0095] S34. Reduce the transmission power of the first antennas to the first transmission power. The absolute value of the difference between the transmission power of the first antennas and the first transmission power is the first power back-off value.

[0096] After the first power back-off value is determined in step S32, the terminal device may control the transmission power of the first antennas to be reduced by the first power back-off value, so that the transmission power of the first antennas is reduced to the first transmission power. For example, for the first antenna A, if the determined power back-off value is 3 dB, the transmission power of the first antenna A can be reduced by 3 dB.

[0097] For at least one second antenna in the non-working state in the antenna system, in one embodiment, the transmission power of the second antennas may be reduced to the second transmission power. Wherein, the absolute value of the difference between the transmission power of the second antennas and the second transmission power is the second power back-off value, and this second power back-off value is the power back-off value of the second antennas when only the second antennas are in the working state in the antenna system. In addition, in another embodiment, the transmission power of the second antennas may not be adjusted, that is, the transmission power of the second antennas remains unchanged.

[0098] In some embodiments of the present disclosure, when the terminal device determines that the specific absorption rate (SAR value) exceeds the standard, it performs the operations of step S32 and step S34.

[0099] First, the terminal device can determine the current specific absorption rate of the terminal device through its own algorithm for calculating the specific absorption rate; next, the current specific absorption rate can be compared with the specific absorption rate threshold, where the specific absorption rate threshold is the critical value to meet the compliance requirements. Due to different local regulations or standards, the specific absorption rate threshold may vary, and it is a known value, which is not limited in the present disclosure.

[0100] If the current specific absorption rate of the terminal device is greater than the specific absorption rate threshold, it means that the current specific absorption rate has exceeded the standard. In this case, the operations of the above-mentioned step S32 and step S34 can be performed.

[0101] The following will refer to Figure 5 to illustrate the entire process of adjusting the antenna power in the embodiments of the present disclosure.

[0102] In step S502, the SAR value of the terminal device can be determined. In step S504, it is judged whether the SAR value of the terminal device exceeds the standard. If it does not exceed the standard, it returns to step S502 to perform the next round of SAR value determination process; if it exceeds the standard, step S506 is executed.

[0103] In step S506, the terminal device determines the antenna combination of the antennas that are simultaneously in the working state in the antenna system it is equipped with.

[0104] In step S508, the terminal device can determine the power back-off value of each antenna in the antenna combination. Among them, in the pre-executed step S500, the power back-off value of each antenna under different antenna combinations can be determined in advance.

[0105] In step S510, the terminal device adjusts the transmission power of each antenna in the working state by using the power back-off value determined in step S508.

[0106] Taking the antenna system of the terminal device including two antennas as an example, the antenna power adjustment process of the present disclosure will be described below. Among them, the first antenna and the second antenna can be any two of a cellular antenna, a WiFi antenna, and a Bluetooth antenna. In addition, as described above, in the case of regarding the 2.4G WiFi antenna and the 5G WiFi antenna as two types of antennas, the first antenna and the second antenna can also be any two of a cellular antenna, a 2.4G WiFi antenna, a 5G WiFi antenna, and a Bluetooth antenna. Those skilled in the art can understand that, in terms of the cellular antenna and the Bluetooth antenna, they can be further divided into multiple types of antennas, and the present disclosure does not limit this.

[0107] The determined first antenna is the antenna in the working state, and the second antenna is the antenna in the non-working state. The first power back-off value can be obtained, and the first power back-off value is used to adjust the transmission power of the first antenna, that is, the transmission power of the first antenna is reduced by the first power back-off value, and the adjusted transmission power is the first transmission power. Among them, the first power back-off value is less than the combined power back-off value of the first antenna, and the combined power back-off value of the first antenna is the power back-off value of the first antenna when both the first antenna and the second antenna are in the working state.

[0108] In addition, on the premise of meeting the SAR value compliance requirements, the second power back-off value can also be determined, and the second power back-off value is used to adjust the transmission power of the second antenna, that is, the transmission power of the second antenna is reduced by the second power back-off value, and the adjusted transmission power is the second transmission power. Among them, the second power back-off value is the power back-off value of the second antenna when only the second antenna in the antenna system is in the working state.

[0109] Next, refer to Figure 6 , taking the antenna system including a cellular antenna and a WiFi antenna as an example, an exemplary implementation scenario of the present disclosure will be described.

[0110] In step S600, the terminal device determines the working states of the cellular antenna and the WiFi antenna. Specifically, the working states of the cellular antenna and the WiFi antenna can be determined when it is determined that the SAR value exceeds the standard.

[0111] In step S612, it is determined that the cellular antenna is in the standby state and the WiFi antenna is in the transmitting state. In this case, step S614 is executed. In step S614, the power back-off value of the WiFi antenna when only the WiFi antenna is working is used to adjust the transmission power of the WiFi antenna, that is, the transmission power of the WiFi antenna is controlled to be reduced by the power back-off value of the WiFi antenna when only the WiFi antenna is working.

[0112] In step S622, it is determined that both the cellular antenna and the WiFi antenna are in the transmitting state. In this case, step S624 is executed. In step S624, the transmit power of the WiFi antenna is adjusted using the power back-off value of the WiFi antenna when the cellular antenna and the WiFi antenna are operating simultaneously (i.e., the combined power back-off value of the WiFi antenna); and the transmit power of the cellular antenna is adjusted using the power back-off value of the cellular antenna when the cellular antenna and the WiFi antenna are operating simultaneously (i.e., the combined power back-off value of the cellular antenna).

[0113] In step S632, it is determined that the WiFi antenna is in the standby state and the cellular antenna is in the transmitting state. In this case, step S634 is executed. In step S634, the transmit power of the cellular antenna is adjusted using the power back-off value of the cellular antenna when only the cellular antenna is operating, that is, the transmit power of the cellular antenna is controlled to be reduced by the power back-off value of the cellular antenna when only the cellular antenna is operating.

[0114] In addition, an embodiment of the present disclosure also provides another antenna power adjustment method, which can be applied to a terminal device. The terminal device includes an antenna system, and the antenna system includes at least one first antenna in the operating state and at least one second antenna in the non-operating state.

[0115] The another antenna power adjustment method may include: reducing the transmit power of the first antenna to a first transmit power, where the first transmit power is greater than the combined transmit power of the first antenna. Here, the combined transmit power of the first antenna is the transmit power obtained by reducing the transmit power of the first antenna by the combined power back-off value of the first antenna, and the combined power back-off value of the first antenna is the power back-off value of the first antenna when all antennas in the antenna system are in the operating state.

[0116] In this embodiment, by configuring the result of reducing the transmit power of the first antenna to be greater than the combined transmit power of the first antenna, the effect of improving the communication ability of the first antenna can be achieved.

[0117] Specifically, the above-mentioned first power back-off value can still be used to reduce the transmit power of the first antenna, so that the determined first transmit power after reduction is greater than the combined transmit power of the first antenna. It can be understood that here it still refers to controlling the transmit power of the first antenna to be reduced by the first power back-off value, and the specific operation process will not be elaborated.
