[0025] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0027] In the following description, references to “some embodiments,” “this embodiment,” “embodiments of the present application,” and examples, etc., describe a subset of all possible embodiments. However, it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

They are only for the convenience of clearly describing the embodiments of the present application and do not constitute any limitation on the embodiments of the present application.

[0029] Before further describing the embodiments of the present application in detail, the nouns and terms that may be involved in the embodiments of the present application are first described. The nouns and terms involved in the embodiments of the present application are subject to the explanations shown in Table 1 below.

[0032]

[0033] To facilitate understanding of the technical solutions of the embodiments of the present application, the following describes the relevant technologies or terms of the embodiments of the present application. The following relevant technologies or terms can be combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application.

[0034] To meet SAR regulatory standards, terminal devices control the transmit power to ensure that the rate of radio frequency energy absorbed by the human body is lower than a certain safety range value recognized by the regulations. Currently, mainstream communication methods of terminal devices (such as cellular communication, WiFi, Bluetooth, NFC, UWB and satellite communication, etc.) are all subject to SAR compliance control. When the terminal device continuously performs business and transmits signals at high power, it may exceed the specific absorption ratio SAR radiation energy limit value within the specified standard time window. Therefore, the terminal device needs to reduce the transmit power to ensure that it meets regulatory requirements. However, reducing the transmit power may result in deterioration of service performance, such as short video freezes, decreased download speeds and decreased upload speeds. To address this problem, the approach adopted in related technology 1 is that the terminal device reduces the transmit power to meet regulatory requirements, compares the power that each antenna port can transmit, and selects the antenna with the highest transmit power for transmission. The approach adopted in related technology 2 is that the terminal device reduces the transmit power to meet regulatory requirements, compares the power that each antenna can transmit and combines the quality of the received signals on each channel, and selects the appropriate antenna for transmission based on this.

[0035] The inventors of this application discovered during their research and analysis of related technology 1 that this solution only considers the transmission power of the current antenna and does not consider the signal reception quality. This may cause the terminal device to switch to an antenna with a poorer reception signal, thereby causing bit errors at the base station due to receiving a poor signal.

[0036] During their research and analysis of Related Art 2, the inventors of this application discovered that while this solution addresses the shortcomings of Solution 1 by taking signal reception quality into account and selecting the antenna with the best current transmit power and received signal, it does not, however, consider the impact of dynamic changes in Specific Absorption Ratio (SAR) radiation on other antennas. Consequently, transmit power remains limited even after antenna switching, potentially leading to performance degradation due to antenna ping-pong switching.

[0037] Based on this, the embodiments of the present application provide the following antenna control methods, devices, equipment, etc.

[0038] Figure 1 Schematic diagram of the implementation process of the antenna control method provided in the embodiment of the present application Figure 1 .like Figure 1 As shown, the method includes the following steps 101 to 104:

[0039] Step 101: determining target transmit power for at least one antenna of the terminal device in a next time window based on transmit energy information of the terminal device in a current time window;

[0040] Step 102: determining an equivalent value of a reception quality parameter of a receiving device in the next time window according to a target transmit power of the first antenna of the terminal device in the next time window;

[0041] Step 103: Select a target antenna from the at least one antenna according to the equivalent value of the reception quality parameter corresponding to each of the at least one antenna in the next time window;

[0042] Step 104: Control the terminal device to use the target antenna transmission power within the next time window.

[0043] It can be understood that in an embodiment of the present application, based on the transmission energy information of the terminal device in the current time window, the target transmission power of at least one antenna of the terminal device in the next time window is estimated; at this time, the working antenna / target antenna in the next time window is not selected based on the target transmission power of each antenna, but it is assumed that the equivalent value of the reception quality parameter of the corresponding receiving device is calculated when the antenna transmits the signal at the target transmission power; and based on the equivalent value of the reception quality parameter, the target antenna is selected from at least one antenna of the terminal device as the working antenna / target antenna for the next time window; this is beneficial to enhancing the receiving performance of the receiving end.

[0044] The following describes further optional implementations and related terms of each of the above steps.

[0045] Step 101: Determine the target transmit power of at least one antenna of the terminal device in the next time window based on the transmit energy information of the terminal device in the current time window.

[0046] In the embodiment of the present application, there is no limitation on the transmission energy information, and the transmission energy information may include the cumulative transmission energy of some antennas or all antennas of the terminal device in the current time window.

[0047] Regarding step 101, in some embodiments, step 101 may further include the following steps 1 and 2:

[0048] Step 1: determining a first accumulated transmission energy of an antenna transmission unit of the terminal device within a current time window;

[0049] In some embodiments, the antenna transmitting unit described in step one can be understood as an antenna set consisting of some or all of the antennas of the terminal device. In other embodiments, the antenna transmitting unit can also be understood as an antenna grouping. An antenna grouping may include one antenna or multiple antennas. In this application, a combination of one or more antennas is referred to as an antenna transmitting unit or an antenna grouping. The cumulative transmission energy of each antenna transmitting unit in the terminal device within the standard time window must meet the SAR regulatory requirements (i.e., predefined constraints). Different antenna transmitting units are deployed in different areas on the terminal device.

[0050] For example, Figure 2 Schematic diagram of the terminal device provided in the embodiment of the present application; Figure 2 As shown, the terminal device 200 includes two antenna transmitting units, namely, antenna transmitting unit 201 and antenna transmitting unit 202; wherein, antenna transmitting unit 201 is deployed in the upper left area of ​​the terminal device 200, and the unit includes antenna ANT0 and antenna ANT1; antenna transmitting unit 202 is deployed in the lower right area of ​​the terminal device 200, and the unit includes antenna ANT2 and antenna ANT3.

[0051] It can be understood that the first accumulated transmit energy refers to the accumulated transmit energy of an antenna transmitting unit in the current time window. This accumulated transmit energy is the sum of the accumulated transmit energies of each antenna in the antenna transmitting unit in the current time window. Taking antenna transmitting unit 201 as an example, the first accumulated transmit energy of antenna transmitting unit 201 in the current time window is the sum of the accumulated transmit energy of antenna ANT0 in the current time window (i.e., the integral of the transmit energy in the current time window) and the accumulated transmit energy of antenna ANT1 in the current time window.

[0052] Step 2: Determine the target transmission power of the first antenna in the antenna transmitting unit in the next time window based on the first cumulative transmission energy and predefined constraints; wherein the predefined constraints constrain the second cumulative transmission energy of the antenna transmitting unit within the standard time window to be less than the first energy threshold, and the sum of the lengths of the current time window and the next time window is the length of the standard time window.

[0053] It can be understood that by combining step one and step two into the overall scheme of the antenna control method, the future transmission power of the first antenna (i.e., the maximum transmission power in the next time window) is determined based on the cumulative transmission energy generated by the antenna transmitting unit in the current time window and the predefined constraints, so that the maximum transmission power is subject to the constraints; at this time, the working antenna in the next time window is not selected based on the maximum transmission power of each antenna, but the reception quality parameter of the first antenna is further combined to determine the equivalent value of the reception quality parameter of the corresponding receiving device when the first antenna is assumed to transmit the signal with the maximum transmission power; and based on the equivalent value of the reception quality parameter, the target antenna is selected from the antennas of at least one antenna transmitting unit of the terminal device as the working antenna for the next time window; in this way, the selected working antenna can not only meet the predefined constraints, but also enhance the receiving performance of the receiving end.

[0054] For step two, based on the first cumulative transmission energy and predefined constraints, determine the target transmission power of the first antenna in the antenna transmitting unit in the next time window; wherein, the predefined constraints constrain the second cumulative transmission energy of the antenna transmitting unit within the standard time window to be less than the first energy threshold, and the sum of the lengths of the current time window and the next time window is the length of the standard time window.

[0055] In some embodiments, the target transmit power of the first antenna in the next time window described in the above step 2 may be the maximum transmit power that the first antenna can transmit in the next time window under the premise of meeting predefined constraints, or the target transmit power of the first antenna in the next time window is less than the maximum transmit power.

[0056] In an embodiment of the present application, the predefined constraint condition complies with SAR regulatory requirements, and the first energy threshold is equal to the upper limit of radiation energy required by the SAR regulatory requirements, or the first energy threshold is less than the upper limit of radiation energy required by the SAR regulatory requirements. The standard time window is the time length specified by the SAR regulatory requirements. For example, the CE standard regulatory window is 360 seconds, that is, the length of the standard time window is 360 seconds; for another example, the FCC standard regulatory window is 100 seconds, that is, the length of the standard time window is 100 seconds. When the cumulative transmission energy of the antenna transmitting unit within the standard time window is lower than the first energy threshold, it indicates that the radiation level of the antenna transmitting unit is within a safe range.

[0057] For example, Figure 3 A schematic diagram of predicting maximum transmit power based on a time window provided in an embodiment of the present application; Figure 3 As shown, the current time window is T1, the next time window is T2, and the sum of the lengths of the current time window and the next time window is the length of the standard time window. It should be understood that the current time window refers to the period from the current moment to a previous moment. In one possible implementation, the standard time window can be divided into N equal parts, where N is greater than 1. Each equal part is referred to as a unit time window. In some embodiments, the length of a unit time window is greater than the minimum length of a signal transmitted by the antenna at one time. In one possible implementation, the next time window is a unit time window.

[0058] In the embodiment of the present application, there is no limitation on the length of the unit time window, and the length of the unit time window can be predefined. For example, the length of the unit time window is 200ms.

[0059] As mentioned above, the predefined constraint conditions constrain the second cumulative transmit energy of the antenna transmitting unit within the standard time window to be less than the first energy threshold, and the sum of the lengths of the current time window and the next time window is the length of the standard time window. Furthermore, based on the first cumulative transmit energy of the antenna transmitting unit in the current time window and the predefined constraint conditions, the target transmit power of the first antenna in the antenna transmitting unit in the next time window is determined. That is, the target transmit power of the first antenna in the next time window is determined under the predefined constraint conditions, and the target transmit power is constrained / limited by the predefined constraint conditions.

[0060] In some embodiments, as Figure 4 As shown, step 2 may further include the following steps 401 and 402:

[0061] Step 401, obtain the mean control power of the first antenna; wherein the mean control power is the average transmission power when the cumulative transmission energy of the first antenna in the standard time window is less than the first energy threshold.

[0062] It should be understood that the average control power of the first antenna can be understood as the average power level of the antenna's continuous transmission under the premise of ensuring compliance with the transmission energy within the standard time window. In one possible implementation, the average control power of the first antenna can be understood as a hardware performance parameter of the first antenna, that is, an inherent parameter, which can reflect the transmission performance of the first antenna. Therefore, the corresponding average control power of first antennas of different models or specifications may be different, and each antenna has its own average control power. In another possible implementation, the average control power of the antenna can be determined based on the historical transmission power of the antenna and the corresponding transmission duration.

[0063] It should be noted that in the embodiment of the present application, the first antenna does not refer to a specific antenna in the antenna transmitting unit, but generally refers to an antenna in the antenna transmitting unit. It is described as the "first antenna" to facilitate the clear description of subsequent embodiments. The "first antenna" here has no specific meaning and can be understood as an antenna.

[0064] Step 402: Determine the target transmit power of the first antenna in the next time window based on the mean control power of the first antenna, the first accumulated transmit energy, and the predefined constraint condition.

[0065] In some embodiments, the target transmit power may be the maximum transmit power of the first antenna in the next time window. In other embodiments, the target transmit power may be less than the maximum transmit power of the first antenna in the next time window.

[0066] It can be understood that in the embodiment of the present application, by obtaining the mean control power, the system can evaluate whether the antenna has a higher power usage potential in the next time window without violating the SAR limit. This helps to select an antenna with better performance for transmission in subsequent decisions. That is, by introducing a method of combining the mean control power with the first cumulative transmission energy, the target transmission power (such as the maximum transmission power) of the next time window is predicted. In this way, on the basis of meeting SAR regulations, the available power range of the antenna in the future period can be more accurately judged, thereby avoiding overly conservative power restrictions and improving communication performance. At the same time, combined with predefined constraints, it is ensured that the prediction results will not violate regulatory requirements, so that intelligent power allocation and antenna switching decisions can be implemented, further enhancing the transmission capacity and stability of the uplink.

[0067] In an embodiment of the present application, the first cumulative transmission energy and the second cumulative transmission energy may be cumulative values ​​obtained by normalizing the transmission power using the mean control power.

[0068] In a scenario where the terminal device uses only one working antenna to transmit power in the next time window, in one possible implementation of step 402, the maximum transmit power of the first antenna in the next time window may be determined according to the following formula (1):

[0069] W T1 +T2*P predict,ANT / P limit,ANT <W REG (1);

[0070] Wherein, T1 is the current time window, T2 is the next time window, and W T1 is the first cumulative emission energy, P predict,ANT is the maximum transmit power of the first antenna in the next time window, P limit,ANT is the average control power of the first antenna, P predict,ANT / P limit,ANT is the transmit power of the first antenna at T2 (normalized value), T2*P predict,ANT / P limit,ANT is the cumulative transmission energy of the antenna transmitting unit at T2, W REG It can be understood that formula (1) is an example of the predefined constraint condition.

[0071] Furthermore, formula (1) can be transformed into the following formula (2):

[0072]

[0073] It can be understood that based on formula (1) or formula (2), the maximum transmission power P of the first antenna in the next time window can be calculated. predict,ANT .

[0074] In a scenario where the terminal device uses M (M is greater than 1) working antennas to transmit power in the next time window, in a possible implementation of step 402, the maximum transmit power of the multiple first antennas in the next time window can be determined according to the following formula (3):

[0075]

[0076] Wherein, ANT j represents the jth first antenna in an antenna transmitting unit, P predict ,ANT j represents the maximum transmit power of the jth first antenna in the next time window, P limit,ANT j represents the average control power of the j-th first antenna.

[0077] Step 102: Determine an equivalent value of a reception quality parameter of a receiving device in the next time window according to a target transmission power of the first antenna of the terminal device in the next time window.

[0078] Further, in some embodiments, step 102 includes: determining an equivalent value of a reception quality parameter of the receiving device in the next time window based on a target transmission power of the first antenna in the next time window and a current reception quality parameter of the first antenna.

[0079] In the embodiment of the present application, the type of the current reception quality parameter of the first antenna is not limited. In short, the parameter is used to represent the signal reception quality of the first antenna. For example, the current reception quality parameter of the first antenna is Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), or Signal to Interference plus Noise Ratio (SINR). For another example, the current reception quality parameter of the first antenna is a comprehensive value of at least two parameters among RSRP, RSRQ, and SINR.

[0080] In the embodiments of the present application, the type of receiving device is not limited. In short, the receiving device is a device that establishes a communication connection with the terminal device and is capable of receiving wireless signals transmitted by the terminal device's antenna. For example, the receiving device can be another terminal device (such as in a D2D communication scenario); for another example, the receiving device can be a network device (such as a wireless access device such as a base station device).

[0081] It will be understood that the equivalent value of the reception quality parameter is a theoretical value estimated based on the target transmit power (e.g., maximum transmit power) of the first antenna in the next time window and the current reception quality parameter of the first antenna. In other words, the equivalent value is the reception quality parameter of the receiving device assuming that the first antenna transmits signals at the target transmit power in the next time window.

[0082] In an embodiment of the present application, the reception quality parameter equivalent value may be an equivalent value of RSRP, RSRQ or SINR, or a comprehensive value of at least two parameter equivalent values ​​of RSRP, RSRQ and SINR.

[0083] For the above steps, based on the target transmit power of the first antenna in the next time window and the current reception quality parameter of the first antenna, an equivalent value of the reception quality parameter of the receiving device in the next time window is determined. In some embodiments, for example Figure 5 As shown, the following steps 501 and 502 may be further included:

[0084] Step 501: Determine the current reception quality parameter of the reference antenna in the terminal device.

[0085] It is understood that a reference antenna refers to an antenna selected as a comparison benchmark in a terminal device, used to evaluate the relative performance of other antennas in the same environment. In the embodiments of the present application, there is no limitation on the reference antenna; the reference antenna can be any transmitting antenna in the terminal device. For example, in some embodiments, the reference antenna can be the currently operating antenna in the terminal device.

[0086] Step 502: Determine the equivalent value of the reception quality parameter of the receiving device in the next time window based on the target transmission power of the first antenna in the next time window, the current reception quality parameter of the first antenna, and the current reception quality parameter of the reference antenna.

[0087] It is understood that the target transmit power can be the maximum transmit power of the first antenna in the next time window. The maximum transmit power refers to the highest power level that the first antenna can transmit in the next time window. This value is affected by regulatory SAR limits. While meeting human safety standards, the transmit power should be increased as much as possible to enhance communication performance.

[0088] In some embodiments, the reception quality parameter equivalent value is a simulated value determined based on the maximum transmit power of the first antenna in the next time window, the current reception quality parameter, and the current reception quality parameter of the reference antenna. This equivalent value is used to estimate the signal quality performance that the receiving end will obtain if the first antenna is used to transmit signals at the first antenna's maximum transmit power in the next time window. This equivalent value comprehensively considers the transmit power and received signal quality, and can more comprehensively guide the selection of antenna switching strategies.

[0089] It can be understood that in the embodiments of the present application, by combining the target transmit power of the first antenna, the current reception quality parameters of the first antenna, and the current reception quality parameters of the reference antenna, the signal reception performance of the receiving device over a period of time in the future can be dynamically predicted, thereby providing data support for antenna switching. In this way, signal degradation caused by blind switching can be avoided, while maximizing communication performance while meeting SAR compliance.

[0090] In some embodiments, the parameter type of the current reception quality parameter of the first antenna, the current reception quality parameter of the reference antenna, and the equivalent value of the reception quality parameter is the same, for example, all are RSRP, RSRQ or SINR; or, all are comprehensive values ​​of RSRP and RSRQ, or all are comprehensive values ​​of RSRP and SINR, or all are comprehensive values ​​of RSRQ and SINR, or all are comprehensive values ​​of RSRP, RSRQ and SINR.

[0091] In step 502, an equivalent reception quality parameter value of the receiving device in the next time window is determined based on the target transmit power of the first antenna in the next time window, the current reception quality parameter of the first antenna, and the current reception quality parameter of the reference antenna. Exemplarily, in one possible implementation, the equivalent reception quality parameter value = the target transmit power of the first antenna in the next time window + the current reception quality parameter of the first antenna - the current reception quality parameter of the reference antenna.

[0092] For example, the equivalent value of the reception quality parameter of the first antenna can be determined according to the following formula (4):

[0093] RecievePower BaseStation,ANT j =P predict,ANT j +RSRP ANT j -RSRP BaseRef (4);

[0094] Among them, RecievePower BaseStation,ANT j represents the equivalent value of the received power of the jth first antenna (ie, ANT j) (ie, an example of the equivalent value of the received quality parameter), P predict,ANT j Indicates the maximum transmit power of the jth first antenna, RSRP ANT j represents the current RSRP of the jth first antenna, RSRP BaseRef Indicates the current RSRP of the terminal device's current working antenna.

[0095] In one possible implementation, the reference antenna is the current working antenna. It can be understood that in the embodiment of the present application, through the above formula (4), the system can quantitatively compare the switching benefits of different antennas, thereby achieving better communication performance optimization while ensuring SAR compliance. By introducing a calculation method for the equivalent value of the reception quality parameter, the impact of antenna switching on the uplink can be more accurately evaluated. In this way, misjudgment caused by relying solely on the maximum transmit power of the antenna can be avoided, thereby achieving more intelligent antenna switching decisions, which can significantly improve communication performance and improve the user's communication experience in a weak field environment.

[0096] Step 103: Select a target antenna from the at least one antenna according to the equivalent value of the reception quality parameter corresponding to each of the at least one antenna in the next time window.

[0097] It can be understood that the equivalent value of the reception quality parameter corresponding to an antenna can be obtained through the above steps. The method for determining the equivalent value of the reception quality parameter corresponding to each antenna of the terminal device is the same. As mentioned above, the terminal device may have one antenna transmitting unit or multiple antenna transmitting units. Through step 103 or a further implementation of step 103 described below, the target antenna can be selected from the antennas of the antenna transmitting units of the terminal device (that is, from all antennas of the terminal device), and the selection is based on the equivalent value of the reception quality parameter corresponding to each antenna.

[0098] In some embodiments, the at least one antenna in step 103 is an antenna of multiple antenna units. Step 103 may further include: selecting a target antenna from the antennas of the multiple antenna transmitting units of the terminal device according to the equivalent values ​​of the reception quality parameters corresponding to the antennas of the multiple antenna transmitting units in the next time window.

[0099] It can be understood that in the embodiment of the present application, the target transmit power of each antenna in the next time window is calculated separately for different antenna transmitting units, and each antenna transmitting unit only needs to meet the predefined constraints separately. However, when selecting a candidate working antenna, the antennas of multiple antenna transmitting units of the terminal device participate in the competition together. In this way, when an antenna of a certain antenna transmitting unit is selected as the working antenna and transmits at the target transmit power in the next time window, the antenna of another antenna transmitting unit is not selected as the working antenna for power transmission. The smaller the cumulative transmit energy, the lower the power used by the antenna in the same time, and the higher the degree of compliance with the SAR limit. Therefore, in the next time window or subsequent time windows, more margin will be accumulated (that is, the difference between the cumulative energy transmitted by the unit in the standard time window and the first energy threshold is large, that is, there is more margin to reach the first energy threshold). Therefore, the antenna of the antenna transmitting unit may have a larger target transmit power subsequently, and thus have a greater chance of being selected as the working antenna. Therefore, under the premise of ensuring the SAR compliance of the terminal device, it is beneficial to extend the time for the working antenna to transmit signals at the target transmit power, thereby improving the communication performance of the terminal device.

[0100] In some embodiments, as Figure 6 As shown, step 103 may further include the following steps 601 and 602:

[0101] Step 601: Select an antenna having the largest equivalent value of the reception quality parameter from the antennas of the at least one antenna transmitting unit as a candidate antenna.

[0102] It can be understood that the equivalent value of the reception quality parameter is used to measure the equivalent performance of an antenna when transmitting a signal to a receiving device at the target transmit power in the current communication state. The higher the equivalent value, the better the communication link quality that the antenna can provide.

[0103] A candidate antenna is an antenna with the highest equivalent value selected after sorting by the equivalent values ​​of the reception quality parameters. This antenna has the best signal transmission capability and, provided it meets the regulatory SAR limits, may become the operating antenna (i.e., the target antenna) in the next time window.

[0104] It can be understood that in the embodiment of the present application, by using the equivalent value of the reception quality parameter as the screening basis, antennas with better signal transmission quality can be preferentially selected, avoiding the problem of increased signal bit error rate due to sole reliance on transmission power, thereby improving the stability and reliability of the communication link.

[0105] In a possible implementation, an antenna having the largest equivalent value of the reception quality parameter is selected from all antennas of the terminal device as a candidate antenna.

[0106] Step 602: Select the target antenna from the candidate antennas and the current working antenna.

[0107] Understandably, Figure 6 In the illustrated embodiment, the target antenna refers to the antenna ultimately selected for power transmission in the next time window, and the currently operating antenna refers to the transmitting antenna currently in use by the terminal device. This embodiment combines the current operating status with the predicted future transmit capability, avoiding the ping-pong effect caused by frequent handovers while maximizing available transmit power while maintaining SAR compliance, thereby improving terminal communication performance.

[0108] In the embodiments of the present application, by introducing equivalent values ​​of reception quality parameters and making a comprehensive judgment based on the currently operating antenna, the optimal transmit antenna under the current conditions can be selected. This can improve the quality perception of the received signal by the receiving device (such as a base station), thereby improving the communication efficiency of the uplink, effectively reducing communication delays, and improving the overall user network experience.

[0109] Furthermore, in some embodiments, step 601 may include: when the candidate antenna is the current working antenna, the current working antenna is the target antenna. That is, in the next time window, the terminal device does not perform antenna switching, but continues to use the current working antenna for signal transmission.

[0110] It's understood that the currently active antenna refers to the antenna port currently used by the terminal device to transmit signals. In wireless communication systems, devices typically support multiple antenna configurations to implement MIMO or multi-antenna switching. The selection of the currently active antenna directly affects uplink transmission performance and the receiving device's assessment of received signal quality.

[0111] In practical applications, if the currently active antenna has the highest equivalent value of the reception quality parameter among all antennas, it indicates optimal transmission capability and reception conditions, and does not violate SAR regulatory limits. Continuing to use this antenna as the active antenna for the next time window can avoid performance fluctuations and resource waste caused by frequent antenna switching. Maintaining a stable antenna connection is crucial for improving the user experience, especially in high-throughput scenarios such as video streaming and online gaming.

[0112] In this embodiment of the present application, by determining whether the candidate antenna is consistent with the current working antenna, a decision is made as to whether to retain the current working antenna as the working antenna (i.e., the target antenna) for the next time window. This reduces the frequency of antenna switching, thereby reducing system resource consumption and improving communication stability and overall performance.

[0113] Furthermore, in some other embodiments, step 601 may include: if the candidate antenna is not the current working antenna, selecting the target antenna from the candidate antenna and the current working antenna based on a relationship between average control powers of the candidate antenna and the current working antenna;

[0114] Among them, the mean control power is the average transmission power when the cumulative transmission energy of the corresponding antenna in the standard time window is less than the first energy threshold.

[0115] It can be understood that the candidate antenna is the antenna with the largest reception quality parameter equivalent value among the antennas of the at least one antenna transmitting unit. When the candidate antenna is not the current working antenna, it means that the reception quality parameter equivalent value corresponding to the candidate antenna is greater than the reception quality parameter equivalent value corresponding to the current working antenna.

[0116] The average controlled power is the maximum permissible average power that meets radiated energy limits. This average power can be used to determine an antenna's suitability for the current communication task, thus preventing SAR (Specific Absorption Rate) violations caused by excessive instantaneous power.

[0117] When the candidate antenna is not the current working antenna, that is, when the candidate antenna has the largest equivalent value of the reception quality parameter among all antennas and is not the current working antenna, by comparing the average control power of the candidate antenna and the current working antenna, it can be determined which antenna has a higher available transmission capability while meeting SAR compliance. If the average control power of the candidate antenna is higher than that of the current working antenna, the candidate antenna is selected as the target antenna to improve communication performance and reduce the possibility of ping-pong switching. In this way, the transmitting antenna can be selected more reasonably, thereby improving the quality of the received signal of receiving equipment such as base stations and enhancing the stability of the uplink; thus, the user's communication experience in weak field environments can be improved, and the overall communication efficiency and performance of the terminal device can be improved.

[0118] Furthermore, in some embodiments, the target antenna is selected from the candidate antennas and the current working antenna based on the relationship between the mean control power of the candidate antenna and the current working antenna, including: if the mean control power of the candidate antenna is greater than the mean control power of the current working antenna, the candidate antenna is selected as the target antenna.

[0119] It can be understood that from the above formula (1), the average control power P of the antenna is limit,ANT The larger the value, the smaller the contribution of the antenna to the radiation of the human body, and the slower the rate of consuming the remaining transmission energy; therefore, if the equivalent value of the reception quality parameter corresponding to the candidate antenna is greater than the equivalent value of the reception quality parameter corresponding to the current working antenna, and the average control power of the candidate antenna is greater than the average control power of the current working antenna, selecting the candidate antenna as the working antenna for the next time window is beneficial to extending the signal transmission time of the terminal device on one antenna while ensuring the SAR compliance of the terminal device and the receiving performance of the receiving device, thereby improving the performance deterioration problem caused by antenna ping-pong switching.

[0120] In some embodiments, the target antenna is selected from the candidate antennas and the current working antenna according to the relationship between the average control power of the candidate antennas and the current working antenna, such as Figure 7 As shown, the following steps 701 to 704 may be further included:

[0121] Step 701: If the average control power of the candidate antenna is less than or equal to the average control power of the current working antenna, determine the third cumulative transmission energy of the candidate antenna when transmitting at the rated transmission power within a preset time period.

[0122] It can be understood that the third cumulative transmit energy is calculated by calculating the total energy generated by the candidate antenna continuously transmitting at its rated transmit power for a preset duration. This parameter is used to predict the upper limit of the candidate antenna's transmit capability after the handover, providing a basis for subsequent decision-making. This allows for an early assessment of the candidate antenna's transmit potential, allowing for a reasonable assessment of its suitability as the next operating antenna, thereby improving overall communication performance and reducing the risk of ping-pong handovers.

[0123] Step 702: Determine the cumulative value of the third accumulated transmission energy and the first accumulated transmission energy of the antenna transmission unit where the candidate antenna is located in the current time window.

[0124] It can be understood that the first accumulated transmission energy is the sum of all transmission energies generated by the antenna transmission unit in the current time window. It is calculated based on historical transmission records and reflects the actual usage of the antenna transmission unit in the past period of time.

[0125] Step 702 adds the predicted third cumulative transmit energy to the current first cumulative transmit energy to obtain a total cumulative transmit energy value. This process helps determine whether switching to the candidate antenna will exceed the energy limits of SAR regulations. This ensures effective control of the total energy before switching, thereby avoiding performance degradation or regulatory violations caused by exceeding safety limits, thereby ensuring communication stability and user health and safety.

[0126] Step 703: If the accumulated value is less than the first energy threshold, select the candidate antenna as the target antenna;

[0127] Alternatively, in step 704, if the accumulated value is greater than or equal to the first energy threshold, the current working antenna is the target antenna.

[0128] It can be understood that if the accumulated value is less than the first energy threshold, it indicates that the candidate antenna still meets the SAR regulatory requirements after switching and has high transmission potential. Therefore, it can be selected as the target antenna, thereby fully utilizing the terminal device's transmission capabilities while ensuring compliance. This can achieve higher transmission efficiency without violating the SAR standard, thereby improving uplink quality, improving the communication experience, and reducing latency.

[0129] If the accumulated value is greater than or equal to the first energy threshold, switching to the candidate antenna would cause the SAR to exceed the standard, so it is safer to continue using the current antenna. This step introduces a conservative strategy to prevent performance fluctuations or regulatory risks caused by excessive switching. This effectively avoids high-risk switching operations, maintaining communication stability, and ultimately extending the device's optimal operating time, improving user satisfaction.

[0130] It can be understood that the above embodiment describes two situations; wherein:

[0131] The first case is: if the reception quality parameter equivalent value corresponding to the candidate antenna is greater than the reception quality parameter equivalent value corresponding to the current working antenna, and the average control power of the candidate antenna is less than or equal to the average control power of the current working antenna, and the accumulated value is less than the first energy threshold, then the candidate antenna is selected as the target antenna;

[0132] It can be understood that in the first case, although the mean control power of the candidate antenna is less than or equal to the mean control power of the current working antenna, if the cumulative value of the third cumulative transmission energy and the first cumulative transmission energy when the candidate antenna transmits at the rated transmission power within the preset time period is less than the first energy threshold specified in the predefined constraint condition, the candidate antenna will still be selected as the target antenna; this is beneficial for the terminal device to transmit signals with a larger transmission power (such as the rated transmission power of the candidate antenna) in the next time window, thereby benefiting the improvement of the uplink performance of the terminal device.

[0133] Among them, in the second case, if the equivalent value of the reception quality parameter corresponding to the candidate antenna is greater than the equivalent value of the reception quality parameter corresponding to the current working antenna, and the average control power of the candidate antenna is less than or equal to the average control power of the current working antenna, and the cumulative value is greater than or equal to the first energy threshold, then antenna switching is not performed, but the current working antenna is used as the working antenna for the next time window. In this way, the SAR of the terminal device is prevented from being non-compliant within the standard time window, that is, the second cumulative transmission energy in the standard time window exceeds the first energy threshold at the end of the next time window.

[0134] It's understood that an antenna's rated power is a hardware performance parameter, or inherent parameter, of the antenna. This parameter represents the maximum RF power the antenna can stably output over a long period of time under specific operating conditions (such as frequency, impedance matching, and ambient temperature). It is determined by the antenna's design parameters (gain, efficiency, and bandwidth) and the supporting RF circuitry (power amplifier and feeder).

[0135] For example, a possible implementation of antenna selection is described as follows:

[0136] Assume that the terminal device includes four antennas ANT0 to ANT3, and the current working antenna of the terminal device is ANTx (x may be 0 / 1 / 2 / 3);

[0137] (1) If RecievePower BaseStation,ANTx If it is the highest value among all antennas, the antenna will not switch and the terminal device will still work on antenna ANTx;

[0138] (2) If the antenna ANTy meets the following conditions: RecievePower BaseStation,ANTy RecievePower BaseStation,ANTx (i.e., antenna ANTy is the candidate antenna), then execute the following step 1:

[0139] Step 1: If the average control power of ANTy is greater than ANTx, that is, P limit,ANTy >P limit,ANTx , then switch the working antenna to antenna ANTy; thereby ensuring that the current TX is on an antenna that can transmit a larger average power; otherwise, if P limit,ANTy ≤P limit,ANTx , then execute step 2;

[0140] Step 2: If W is satisfied groupA,T1 +T min_gap *P max,ANTy / P limit,ANTy <W REG , the working antenna is switched to antenna ANTy; otherwise, it remains at ANTx.

[0141] Among them, W groupA,T1 is the first cumulative transmission energy of the antenna transmitting unit where the antenna ANTy is located in the current time window, T min_gap is the preset time mentioned above, P max,ANTy is the rated transmission power of antenna ANTy, T min_gap *P max,ANTy / P limit,ANTy The antenna ANTy is set to groupA,T1 Rated transmit power P max,ANTy The third cumulative transmission energy when transmitting; W REG is the first energy threshold.

[0142] Step 104: Control the terminal device to use the target antenna transmission power within the next time window.

[0143] It is understood that if the target antenna is the currently working antenna, the terminal device does not switch antennas when the next time window arrives, but maintains the current working antenna and continues to transmit signals using the antenna in the next time window. If the target antenna is not the currently working antenna, the terminal device switches antennas when the next time window arrives.

[0144] The following examples describe possible implementations of the antenna control method described in one or more of the above embodiments.

[0145] In the following implementation scheme, by combining the maximum transmit power of each antenna of the current radio unit, the RSRP of the received signal, and the cumulative value of the radiation energy value in the current time window, a better-performing antenna can be selected for signal transmission, which can significantly improve the communication experience brought to the end user by the radio unit.

[0146] Figure 8 A schematic diagram of the framework of the implementation scheme provided in the embodiment of the present application; Figure 8 As shown, the framework of the implementation solution includes a radiation energy control unit 801, an information collection unit 802, an antenna switching decision unit 803, an antenna switching control unit 804, a transceiver, and antenna 0 (ANT0) to antenna 3 (ANT3).

[0147] Information collection unit 802, used to collect information about each transceiver's antenna position, transmit power, maximum transmit power allowed on each antenna, and RSRP of the received signal on each antenna;

[0148] The radiation energy control unit 801 is used to calculate the cumulative transmission energy W in the current time window T1 based on the historical radiation power value of the Transceiver. T1 , and determine the maximum power P that all current antennas can transmit in the next time window T2 predict,ANT0 , P predict,ANT1 , P predict,ANT2 , P predict,ANT3 .

[0149] The specific process is as follows:

[0150] The transmission energy value of an antenna is obtained by multiplying the transmission energy value of the antenna by the transmission time of the antenna. The energy value is accumulated to obtain the cumulative transmission energy W of the current time window T1. T1 , under the condition that the cumulative transmitted energy value in the entire standard time window is lower than the SAR value constraint, it is used to determine the maximum power that can be transmitted in the next time window T2. The corresponding formula is shown in the following formula (5):

[0151] (WT1 +T2*P predict,ANT / P limit,ANT )<W REG

[0152]

[0153] Figure 9 A schematic diagram of determining the maximum transmit power based on a time window provided in an embodiment of the present application; Figure 9 As shown, the total accumulated transmit energy of all transmit antennas in the current time window T1 is normalized, and based on this, the normalized transmit energy value allowed in the target unit time window T2 is determined.

[0154] It should be noted that the length of the unit time window can be customized by the manufacturer. In short, the standard time window specified by the regulations can be divided into N equal parts, where N is greater than 1. In addition, the unit time window is greater than the minimum time (i.e., minimum duration) of each transmission of the terminal device.

[0155] Total time length T REG :T1+T2=T REG ; Among them, T REG This is the standard time window specified by regulations. For example, the CE standard window is 360 seconds, and the FCC standard window is 100 seconds. T2 is customized by the manufacturer, for example, it can be defined as 200ms.

[0156] When the antennas are far enough apart, the SPLSR concept introduced in FCC regulation KDB447498D01 GeneralRF Exposure Guidance v06 can be used to group antennas into multiple antenna transmission units. Each group can ensure that the cumulative transmission energy of its regulatory time window (i.e., standard time window) meets the regulatory standards. For example, Figure 2 A schematic diagram of grouping antennas of a terminal device provided in an embodiment of the present application; Figure 2 As shown, considering that the distance between antenna ANT0 and antenna ANT1 is relatively close, the distance between antenna ANT2 and antenna ANT3 is relatively close, and the distance between ANT0 and ANT1 and ANT2 and ANT3 is relatively far, antenna ANT0 and antenna ANT1 can be classified into group A (i.e. Group A, also known as antenna transmitting unit A), and antenna ANT2 and antenna ANT3 can be classified into group B (i.e. Group B, also known as antenna transmitting unit B). The maximum power transmitted in the next time window T2 is calculated based on the cumulative transmission energy of the antennas in each group in the current time window.

[0157] The maximum power transmitted by ANT0 or ANT1 in the next time window T2 is expressed as follows:

[0158] (W groupA,T1 +T2*P predict,ANTj / P limit,ANTj )<W REG

[0159]

[0160] Wherein, in formula (6), j = 0 or 1;

[0161] The maximum power transmitted by ANT2 or ANT3 in the next time window T2 is expressed as follows:

[0162] W groupB,T1 +T2*P predict,ANTj / P limit,ANTj <W REG

[0163]

[0164] Wherein, in formula (7), j = 2 or 3;

[0165] The antenna switching decision unit 803 is used to select an antenna based on the maximum transmit power of each antenna calculated by the radiation energy control unit 801 and the RSRP (SNR) received by the information acquisition unit 802 (the SNR may also be considered). The overall decision strategy is as follows:

[0166] a. Calculate the maximum power P that each antenna of the terminal device can transmit based on the radiation energy control unit 801 predicAt,NT0 、P predict,ANT1 、P predict,ANT2 、P predict,ANT3 and the RSRP of the current corresponding antenna ANT0 、RSRP ANT1 、RSRP ANT2 、RSRP ANT3 Based on this, the equivalent value of the base station's received power is calculated as shown in the following formula (8): BaseStaion,ANT0 、RecievePower BaseStation,ANT1 、RecievePower BaseStation,ANT2 and RecievePower BaseStation,ANT3 :

[0167] RecievePower BaseStation,ANTx =P predict,ANTx +RSRP ANTx -RSRP BaseRef (8);

[0168] Among them, P predict,ANTxis the maximum power that antenna ANTx can transmit, RSRP ANTx RSRP of the terminal device's antenna ANTx; ReceivePower BaseStation,ANTx The transmission power of the antenna ANTx at the terminal device is P predict,ANTx In the case of , the equivalent value of the corresponding received power on the base station side (i.e., an example of the equivalent value of the reception quality parameter);

[0169] b. Assume that the terminal device's Transceiver TX is currently transmitting on antenna ANTx (x may be 0 / 1 / 2 / 3). If RecievePower BaseStation,ANTx If it is the highest value among all antennas, the antenna will not switch and will remain at ANTx.

[0170] c. If the antenna ANTy meets the RecievePower BaseStation,ANTy >RecievePower BaseStation,ANTx , then execute step 1 or step 2 as follows:

[0171] Step 1: If the average control power of antenna ANTy is greater than ANTx P limit,ANTy >P limit,ANTx , then immediately switch to ANTy to ensure that the current TX is on an antenna that can transmit a larger average power; otherwise, execute step 2;

[0172] Step 2: If W is satisfied groupA,T1 +T min_gap *P max,ANTy / P limit,ANTy <W REG , then switch to ANTy, where T min_gap For the set P max,ANTy The minimum transmission time is to ensure that the antenna can be switched at least with P max,ANTy Emit a certain time P max,ANTy ; Otherwise continue to stay in ANTx;

[0173] The antenna switching control unit 804 is configured to control the Transceiver to select a corresponding antenna for power transmission according to the antenna switching decision result.

[0174] Figure 10 Schematic diagram of the implementation process of the antenna control method provided in the embodiment of the present application Figure 2 ;like Figure 10 As shown, the method includes the following steps 1001 to 1005:

[0175] Step 1001, calculating the historical radiation energy of corresponding groups on multiple antennas;

[0176] Step 1002: Calculate the maximum power that each antenna can transmit at a future time T2 based on the historical radiation energy.

[0177] Step 1003, obtaining the current RSRP of each antenna;

[0178] Step 1004: Calculate the equivalent value of the received power of the base station when each antenna transmits based on the RSRP and the future maximum transmit power (i.e., an example of the target transmit power);

[0179] Step 1005: Based on the equivalent value of the base station's received power of each antenna, the radiation energy value of the group time window, the maximum transmit power of each antenna, and the average control power, determine the antenna that needs to be switched, and switch to the corresponding antenna by controlling the Transceiver.

[0180] It can be understood that in the above implementation scheme, the TX of the terminal device is allowed to switch to an antenna that enables the base station side to receive better power, thereby enhancing the uplink transmission capability of the terminal device and enhancing the communication performance.

[0181] It can be understood that in the above implementation, the access capability and connection capability of the wireless unit can be improved in a weak field, thereby improving the user's weak field communication experience.

[0182] Table 2 shows the stuttering performance of the above-mentioned implementation scheme (i.e., this technical scheme) and the above-mentioned related technology 2 in the game scene; as shown in Table 2, compared with related technology 2, the overall stuttering rate of this technical scheme is reduced from 0.96% to 0.13%, and the effect is obvious.

[0183] Table 2

[0184]

[0185] As you can understand, in the above implementation, future transmit power is determined based on the radiated energy value, and the base station's equivalent received power is introduced in conjunction with RSRP. This ensures that the terminal device's TX signal is located on the antenna that best receives the base station signal, thereby improving uplink performance. This means that the terminal device's antenna transmits at a power level that meets regulatory requirements while ensuring base station reception performance.

[0186] It can be understood that in the above implementation scheme, SPLSR grouping and antenna switching are combined, and the future transmission power and accumulated transmission energy are calculated separately for the radiation energy values ​​of antennas in different groups, and introduced into antenna switching to ensure that the duration of maximum transmission power can be increased under the premise of compliance.

[0187] It should be noted that the above implementation scheme is applicable to terminal devices with multiple wireless transmission units, including but not limited to mobile phones, tablets, and wearable watches. Multiple wireless transmission units include but are not limited to cellular, WiFi, BT, satellite communication, UWB, and NFC. In the embodiments of this application, the type of antenna is not limited and can support the transmission of at least one of cellular, WiFi, BT, satellite communication, UWB, and NFC signals.

[0188] It should be noted that although the steps of the method of the present application are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all steps must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps; or steps in different embodiments may be combined to form a new technical solution.
