Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

Referring to fig. 1, a flowchart of an implementation of a communication control method provided in an embodiment of the present application is shown, where the method may be applied to a communication device that has an antenna and is capable of performing signal transmission, such as a mobile phone. The technical scheme in the embodiment is mainly used for adjusting radiation generated by signal transmission of the communication equipment.

Specifically, the method in this embodiment may include the following steps:

step 101: the current usage status of the communication device is obtained.

The communication equipment comprises at least two first antennas required by a first communication type and at least two second antennas required by a second communication type. The first communication type may be a Mobile hotspot WiFi type, and the second communication type may be a Mobile communication type, such as 5G (5th generation Mobile networks), 4G such as LTE-a (Long Term Evolution-Advanced), or worldwide Interoperability for Microwave access wimax (world Interoperability for Microwave access), 3G such as universal Mobile Telecommunications System umts (universal Mobile Telecommunications System), or LTE, 2G such as global System for Mobile communications gsm (global System for Mobile communications), and so on.

In this embodiment, taking the communication device as an example of a mobile phone, the mobile phone includes at least two first antennas of a WiFi type, which are denoted by tx0 and tx1, and also includes at least two second antennas of a mobile communication type, such as a 5G antenna and a 4G antenna. Each antenna corresponds to a group of radio frequency transmitting channels respectively, and the antennas transmit signals through the radio frequency transmitting channels. The mobile phone realizes multiple communication modes of WiFi based on the first antennas, such as a multiple-in multiple-out (MIMO) mode and the like.

It should be noted that the current usage state at least includes that the communication module of the first communication type is in an operating state. That is, in the present embodiment, the communication module of the first communication type is in an operating state, and the communication module of the second communication type may or may not be in an operating state, based on which the current usage state of the communication device obtained in the present embodiment is a state in which the communication module of the first communication type is in an operating state and the communication module of the second communication type may or may not be in an operating state.

Taking the communication device as a mobile phone as an example, the current usage state of the mobile phone obtained in this embodiment is that the communication module of WiFi is in a running state, and the communication module of 5G or 4G may or may not be in a running state.

Step 102: and according to the current use state, obtaining communication limiting parameters of different radio frequency transmitting channels aiming at different working frequency bands corresponding to the communication module of the first communication type in the current use state.

In this embodiment, the communication limitation parameters for limiting the rf transmission path to perform signal transmission are obtained by analyzing the current usage state, and these communication limitation parameters may include a limitation parameter of the transmission power.

Specifically, the communication restriction parameter obtained in this embodiment is a parameter corresponding to the communication module of the first communication type, and includes communication restriction parameters of different radio frequency transmission paths on a plurality of different operating frequency bands. That is to say, the communication restriction parameters obtained in this embodiment include the communication restriction parameters corresponding to each first antenna in a plurality of different operating frequency bands in the current use state. Taking a mobile phone as an example, the communication limiting parameter includes a transmission power limiting parameter of each first antenna of the WiFi on a plurality of working frequency bands.

It should be noted that the working frequency band herein may include 4 frequency points in the 2.4GHz band and the 5GHz band, and is represented by a frequency point b1 in the 5GHz band, a frequency point b2 in the 5GHz band, a frequency point b3 in the 5GHz band, and a frequency point b4 in the 5GHz band.

Step 103: in a current use state, if the communication module of the first communication type operates based on the first operating frequency band, the signal transmission of the radio frequency transmission path corresponding to the first operating frequency band is limited by the communication limitation parameter corresponding to the first operating frequency band.

Specifically, when the radio frequency transmission path is adjusted, the adjustment is performed according to the current operating frequency band of the communication module of the first communication type. That is to say, when performing adjustment, in this embodiment, the working frequency band in which the communication module of the first communication type is currently located is determined first, for example, the 2.4GHz frequency band in which the communication module of the first communication type is located is determined first, and then the frequency point in the 5GHz frequency band in which the communication module of the first communication type is located is determined through frequency point detection. Therefore, in this embodiment, the operating frequency band in which each first antenna is located is determined, so as to obtain the first operating frequency band in which each first antenna is located, where it is to be specifically described here that one first antenna may correspond to one first operating frequency band, and may also correspond to two operating frequency bands, for example, the first antenna of WiFi is only located in the frequency band of 2.4GHz, or the first antenna of WiFi is located in one frequency point of the frequency bands of 2.4GHz and 5 GHz.

Therefore, in the communication limiting parameters obtained in step 102, the communication limiting parameter corresponding to the first operating frequency band in which each first antenna is located is obtained, and based on this, the signal transmission of the radio frequency transmission path corresponding to the first operating frequency band may be limited by the communication limiting parameter corresponding to the first operating frequency band, so as to adjust the radiation generated by signal transmission of the communication device.

Taking a mobile phone as an example, in this embodiment, after obtaining the transmit power limiting parameters of each first antenna of the WiFi on multiple working frequency bands, the first working frequency band where each first antenna of the WiFi is located is determined through frequency point detection, and then the transmit power limiting parameters corresponding to the first working frequency band where each first antenna is located are obtained, so that the transmit power of the transmit signal can be limited for the radio frequency transmit path of each first antenna according to the transmit power limiting parameters corresponding to the first working frequency band where each first antenna is located.

Specifically, the communication limitation parameter includes a limitation value for the communication parameter value, which may include a maximum value and/or a minimum value. Therefore, when the signal transmission of the radio frequency transmission path corresponding to the first working frequency band is limited, the following limiting modes can be adopted:

and limiting the communication parameter value of the signal transmitted by the radio frequency transmission path corresponding to the first working frequency band to be less than or equal to the maximum value, and/or limiting the communication parameter value of the signal transmitted by the radio frequency transmission path corresponding to the first working frequency band to be greater than or equal to the minimum value.

Taking a mobile phone as an example, in this embodiment, after obtaining the transmit power limiting parameters of each first antenna of the WiFi on multiple working frequency bands, the transmit power limiting parameters include the maximum value of the transmit power, and based on this, the first working frequency band where each first antenna of the WiFi is located is determined through frequency point detection, and then the maximum value of the transmit power corresponding to the first working frequency band where each first antenna is located is obtained, so that the maximum power of the radio frequency transmit path of each first antenna for signal transmission can be respectively limited not to exceed the maximum value of the transmit power corresponding to the first working frequency band where the first antenna is located, thereby realizing power limitation and avoiding higher radiation caused by excessively high transmit power.

As can be seen from the foregoing solution, in a communication control method provided in this embodiment of the present application, by obtaining a current use state of a communication device, since the current use state includes an operation state of a communication module of a first communication type, after obtaining communication limitation parameters for different radio frequency transmission paths of different operation frequency bands corresponding to the communication module of the first communication type according to the current use state, in the current use state, if the communication module of the first communication type operates based on the first operation frequency band, signal transmission of the radio frequency transmission path corresponding to the first operation frequency band is limited by the communication limitation parameters corresponding to the first operation frequency band. Therefore, in this embodiment, signal transmission of the radio frequency transmission path corresponding to the antenna is limited according to the use state of the communication device, so that the purpose of adjusting radiation generated by signal transmission can be achieved while signal transmission of the radio frequency transmission path is guaranteed.

In an implementation manner, when obtaining, according to the current usage state, communication restriction parameters of different radio frequency transmission paths corresponding to different operating frequency bands on a communication module of a first communication type in the current usage state in step 102, specifically, the following manner may be implemented:

and according to the current use state, obtaining a target limiting parameter group corresponding to the current use state in a preset limiting parameter list.

Wherein the list of restriction parameters may be stored in the communication device. And the limiting parameter list may include a plurality of limiting parameter sets, one limiting parameter set corresponding to a use status of one communication device. Therefore, the obtained target limiting parameter group comprises communication limiting parameters of different radio frequency transmission paths corresponding to different working frequency bands on the communication module of the first communication type in the current use state.

Specifically, the limiting parameter list in this embodiment may be represented in a matrix form, where each row of limiting parameters is a limiting parameter group, and each row of limiting parameters corresponds to a use state of the communication device. The restriction parameters in the corresponding rows may be different, with different usage states. Each row of limiting parameters, that is, each limiting parameter group, includes communication limiting parameters of different rf transmission paths corresponding to the communication module of the first communication type in the use state corresponding to the limiting parameter group, for example, includes communication limiting parameters of an rf transmission path through which each first antenna performs signal transmission on each operating frequency band.

As shown in fig. 2, tx0 and tx1 respectively represent two first antennas, and for example, a b1 frequency point of a 2.4GHz band and a 5GHz band, a b2 frequency point of a 5GHz band, a b3 frequency point of a 5GHz band, and a b4 frequency point of a 5GHz band are taken as examples, a limiting parameter list includes multiple rows of limiting parameters, each row of limiting parameters is a limiting parameter group, and one limiting parameter group includes maximum transmission power values of radio frequency transmission paths corresponding to the b1 frequency point of the 2.4GHz band and the 5GHz band, the b2 frequency point of the 5GHz band, the b3 frequency point of the 5GHz band, and the b4 frequency point of the 5GHz band of the two first antennas in a corresponding use state.

Taking a mobile phone as an example, after obtaining the usage status of the mobile phone in this embodiment, according to the usage status of the operation status of the communication module including WiFi, the maximum transmission power values of each first antenna of WiFi in the 2.4GHz band, the b1 frequency point of the 5GHz band, the b2 frequency point of the 5GHz band, the b3 frequency point of the 5GHz band, and the b4 frequency point of the 5GHz band in this usage status are obtained in fig. 2, that is, the maximum transmission power value of one row corresponding to the corresponding usage status is obtained, then, the first operating frequency band where each first antenna of WiFi is located is determined through frequency point detection, for example, tx0 is at b1 frequency points of the 2.4GHz band and the 5GHz band, tx1 is at b2 frequency points of the 2.4GHz band and the 5GHz band, and the maximum transmission power value of the first operating frequency band where each first antenna is located is obtained in the previously obtained row of maximum transmission power values, for example, tx0 corresponds to 11.5 mw at the 2.4GHz band, tx0 corresponds to 8.5 mw at the b1 frequency point of the 5GHz band, tx1 corresponds to 11.5 mw at the 2.4GHz band, tx1 corresponds to 9.5 mw at the b2 frequency point of the 5GHz band, so that the maximum power of signal transmission by the radio frequency transmission channel of each first antenna is limited not to exceed the maximum value of the transmission power corresponding to the first operating band where the first antenna is located, for example, the transmission power of tx0 at the 2.4GHz band is limited not to exceed 11.5 mw, the transmission power of tx0 at the b1 frequency point of the 5GHz band is limited not to 8.5 mw, the transmission power of tx1 at the 2.4GHz band is limited not to exceed 11.5 mw, and the transmission power of tx1 at the b2 of the 5GHz band is limited not to exceed 9.5 mw, thereby achieving the power limitation and avoiding higher radiation caused by excessive radiation power.

In one implementation, the current usage state of the communication device may include a first operation state of a first antenna required by the first communication type, a second operation state of a second antenna required by the second communication type, and a posture of the communication device relative to the user.

The first operation state may be any one of the following states:

in one case, the first operating state is: the first antenna is connected to the communication access point to enable the communication device to conduct signal transmission through a radio frequency transmission path of the first antenna.

That is, the first operating state may be a state in which the communication device is connected to the communication access point through the first antenna and signal transmission is achieved using the first antenna. Taking a mobile phone as an example, the first operation state is a state in which WiFi is connected to a communication access point such as a network router or the like so that the mobile phone performs signal transmission through WiFi, as shown in fig. 3. The mobile phone performs signal transmission through WiFi, which may be a case where the mobile phone performs data uploading and downloading through WiFi, or a case where the mobile phone performs voice call or video call through WiFi.

In another case, the first operating state is: the first antenna is connected with other equipment so that the communication equipment can carry out signal transmission with other equipment through a radio frequency transmission path of the first antenna.

That is to say, the first operating state may be a state in which the communication device directly connects with the other device through the first antenna to implement signal transmission between the communication device and the other device. Taking a mobile phone as an example, the first operation state is as follows: the handset is directly connected to another handset through WiFi to implement p2p mode and thus data upload and download or talk status, as shown in fig. 4.

In another case, the first operating state is: the first antenna is connected with other equipment so that the other equipment can carry out signal transmission through a radio frequency transmission path of the first antenna.

That is, the first operation state may be a state in which the communication apparatus provides the other apparatus with a function of performing signal transmission via the first antenna. Taking a mobile phone as an example, the first operation state is as follows: the mobile phone is used as a network access hotspot through WiFi so that another mobile phone can realize the states of data uploading and downloading or conversation, as shown in fig. 5.

And the second operating state may be any one of the following states:

in one case, the second operating state may be: and the radio frequency transmitting path of the second antenna at the first position on the communication equipment is in a signal transmission state.

In another case, the second operating state may be: a state that the radio frequency transmission path of the second antenna at a second position on the communication equipment carries out signal transmission;

in another case, the second operating state may be: the radio frequency transmitting path of the second antenna at the first position and the radio frequency transmitting path of the second antenna at the second position both stop signal transmission;

the first position is different from the second position, and the performance parameters for realizing communication are different between the second antenna at the first position and the second antenna at the second position on the communication equipment although the communication types are the same. Taking a mobile phone as an example, the first position is a top of the mobile phone, i.e., a position close to the earpiece, the second antenna in the first position may be a 5G antenna, the second position is a bottom of the mobile phone, i.e., a position close to the microphone, the second antenna in the second position may be a 4G antenna, and the communication performance achieved by the 5G antenna is better than that achieved by the 4G antenna.

That is, the second operation state can be classified into the above cases: the second antenna in the first position is in operation and the second antenna in the second position is not in operation, the second antenna in the second position is in operation and the second antenna in the first position is not in operation, and neither the second antenna in the first position nor the second antenna in the second position is in operation.

Taking a mobile phone as an example, the second operation state of the second antenna required by the second communication type may have several situations: the state that the top 5G antenna transmits signals through its radio frequency transmission path, such as a mobile phone surfing the internet or talking through 5G, is shown in fig. 6; the state that the 4G antenna at the bottom performs signal transmission through its radio frequency transmission path, such as a mobile phone surfing the internet or talking through 4G, is shown in fig. 7; the state that the top 5G antenna and the bottom 4G antenna do not perform signal transmission, such as the state that the mobile phone closes the mobile communication network, as shown in fig. 8, and so on.

Of course, in other embodiments, the second antenna at the second position may also be an LTE, 3G, or 2G antenna, and the like, and all the implemented technical solutions are within the protection scope of the present application and will not be described in detail here.

In addition, the posture of the communication device relative to the user may include the following cases:

in one case, the pose of the communication device with respect to the user may be: gestures where the distance between the communication device and the user is greater than or equal to a first threshold. Wherein the first threshold may be determined from historical data, for example by setting the first threshold according to a maximum radiation distance that has an impact on the user. Taking a mobile phone as an example, the gesture of the mobile phone relative to the user may be a gesture that the distance between the mobile phone and the user is greater than a first threshold, that is, the mobile phone is away from the user, for example, a state that the user places the mobile phone on a desktop and opens the external player to perform a video call is shown in fig. 9.

In another case, the pose of the communication device with respect to the user may be: the distance between the communication device and the first operation body of the user is smaller than or equal to a second threshold value. Wherein the second threshold may be determined from historical data. The second threshold is less than the first threshold. That is, the posture of the communication device with respect to the user is a posture in which the communication device approaches the first manipulation body of the user.

In another case, the distance between the communication device and the second operation body of the user is less than or equal to the third threshold. Wherein the third threshold may be determined from historical data. The third threshold is less than the first threshold. That is, the posture of the communication device with respect to the user is a posture in which the communication device approaches the second manipulation body of the user.

Wherein the second threshold is different from the third threshold. The difference between the first operation body and the second operation body is that the first operation body is a specific operation body that is in direct contact with the communication device, and the second operation body is an operation body that is close to the communication device but may have another object interposed therebetween. The second threshold is lower than the third threshold. Taking a mobile phone as an example, the first operation body may be a head of a user, and when the user uses a handset to perform a voice call, the head of the user directly contacts the mobile phone, as shown in fig. 10; the second manipulation body may be a user's body such as the user's abdomen, chest or legs, with clothing spaced between the user's body and the mobile phone when the user places the mobile phone in a pocket of clothing, as shown in fig. 11.

It should be noted that the first operating state, the second operating state, and the posture of the communication device are different, and the communication limitation parameters obtained correspondingly are different.

Based on the above, the usage status of the communication device comprises at least three parts: the status part corresponding to the first antenna, the status part corresponding to the second antenna and the posture part of the communication device relative to the user, based on which, through the combination of different situations, the use status of the communication device can include the following situations:

one of the situations is: the first antenna is connected to the communication access point so that the communication device can perform signal transmission through the radio frequency transmission path of the first antenna, or the first antenna is connected with other devices so that the communication device can perform signal transmission with other devices through the radio frequency transmission path of the first antenna, or the first antenna is connected with other devices so that other devices can perform signal transmission through the radio frequency transmission path of the first antenna.

That is, in this case, only the first antenna is in operation and the second antenna is not.

One of the conditions is as follows: the first antenna is connected to the communication access point so that the communication device performs signal transmission through the radio frequency transmission path of the first antenna, and the radio frequency transmission path of the second antenna at the first position on the communication device performs signal transmission.

Taking a mobile phone as an example, in this case, the mobile phone performs network connection through WiFi, and at the same time, the mobile phone performs communication through the top 5G antenna.

One of the situations is: the first antenna is connected to the communication access point such that the communication device is in a state of transmitting signals through the radio frequency transmission path of the first antenna and the radio frequency transmission path of the second antenna at a second location on the communication device.

Taking a mobile phone as an example, in this case, the mobile phone performs network connection through WiFi, and at the same time, the mobile phone performs communication through a 4G antenna at the bottom.

One of the situations is: the first antenna is connected with other devices, so that the other devices can perform signal transmission through the radio frequency transmission path of the first antenna, and the radio frequency transmission path of the second antenna at the first position on the communication device can perform signal transmission.

Taking a mobile phone as an example, in this case, the mobile phone serves as a network access hotspot through WiFi, and is provided for other mobile phones to perform network connection, and meanwhile, the mobile phone performs communication through a 5G antenna at the top.

One of the situations is: the first antenna is connected with other devices, so that the other devices can carry out signal transmission through the radio frequency transmission path of the first antenna, and the radio frequency transmission path of the second antenna at the second position on the communication device is in a signal transmission state.

Taking a mobile phone as an example, in this case, the mobile phone serves as a network access hotspot through WiFi, and is provided for other mobile phones to perform network connection, and meanwhile, the mobile phone performs communication through a 4G antenna at the bottom.

In one case, the first antenna is connected to the other device, so that the other device performs signal transmission through a radio frequency transmission path of the first antenna, and a distance between the communication device and the first operation body of the user is smaller than or equal to the second threshold.

Taking a mobile phone as an example, in this case, the mobile phone performs network connection through WiFi, and meanwhile, the mobile phone approaches the head of the user in the network conversation process using WiFi.

One of the conditions is as follows: the first antenna is connected to the communication access point, so that the communication equipment performs signal transmission through the radio frequency transmission path of the first antenna, the radio frequency transmission path of the second antenna at the first position on the communication equipment performs signal transmission, and the distance between the communication equipment and the first operation body of the user is smaller than or equal to a second threshold value.

Taking a mobile phone as an example, in this case, the mobile phone performs network connection through WiFi, and meanwhile, the mobile phone approaches the head and performs communication through a 5G antenna at the top.

One of the situations is: the first antenna is connected to the communication access point, so that the communication equipment performs signal transmission through the radio frequency transmission path of the first antenna, the radio frequency transmission path of the second antenna at a second position on the communication equipment performs signal transmission, and the distance between the communication equipment and the first operation body of the user is smaller than or equal to a second threshold value.

Taking a mobile phone as an example, in this case, the mobile phone performs network connection through WiFi, and meanwhile, the mobile phone approaches the head and performs communication through the 4G antenna at the bottom.

One of the situations is: the first antenna is connected to the communication access point, so that the communication equipment performs signal transmission through a radio frequency transmission path of the first antenna, and the distance between the communication equipment and the second operation body of the user is smaller than or equal to a third threshold value.

Taking a mobile phone as an example, in this case, the mobile phone performs network connection through WiFi, and meanwhile, the mobile phone is placed in a user's pocket.

One of the conditions is as follows: the first antenna is connected to the communication access point, so that the communication device performs signal transmission through the radio frequency transmission path of the first antenna, the radio frequency transmission path of the second antenna at the first position on the communication device performs signal transmission, and the distance between the communication device and the second operation body of the user is smaller than or equal to a third threshold value.

Taking a mobile phone as an example, in this case, the mobile phone performs network connection through WiFi, and at the same time, the mobile phone is placed in a pocket and performs communication through a top 5G antenna.

One of the situations is: the first antenna is connected to the communication access point, so that the communication device performs signal transmission through the radio frequency transmission path of the first antenna, the radio frequency transmission path of the second antenna at the second position on the communication device performs signal transmission, and the distance between the communication device and the second operation body of the user is smaller than or equal to a third threshold value.

Taking a mobile phone as an example, in this case, the mobile phone performs network connection through WiFi, and at the same time, the mobile phone is placed in a pocket and performs communication through a 4G antenna at the bottom.

Of course, the usage status of the communication device in this embodiment may also include other situations, which are not described in detail herein.

In a specific implementation, when the current usage state of the communication device is obtained in step 101, the following processing is performed:

the method includes the steps that a first operation state is obtained by monitoring the current working state of a first antenna, for example, whether the first antenna is connected to a communication access point, is directly connected with other equipment, is used as a network access hotspot by other equipment or not is monitored, and the first operation state is obtained;

the current working state of the second antenna is monitored to obtain a second running state, for example, whether the second antenna at each position on the communication equipment carries out signal transmission is monitored, and if the second antenna is in a state of uploading and downloading data or in a state of a call in progress, the second running state is obtained;

the distance information relative to the user is collected through a sensor on the communication device, and then the posture of the communication device relative to the user is obtained.

In one implementation manner, when the signal transmission of the radio frequency transmission path corresponding to the first operating frequency band is limited by the communication limitation parameter corresponding to the first operating frequency band in step 103, the following may be implemented:

Specifically, the communication restriction instruction may include a communication restriction parameter corresponding to each first antenna corresponding to the first communication type in the corresponding first operating frequency band, so that after the communication restriction instruction is sent to the controller corresponding to each first antenna, the controller on the first antenna triggers the radio frequency transmission path on the first antenna to restrict signal transmission according to the corresponding communication restriction parameter, for example, to restrict the transmission power of the signal.

The controller corresponding to the first antenna may be a control chip of the antenna, the control chip has a storage area therein, and after receiving a communication restriction instruction sent by the communication device on the controller, the controller analyzes the communication restriction instruction, so as to analyze a plurality of communication restriction parameters included in the communication restriction instruction, for example, the communication restriction parameters corresponding to each first antenna on one or more first operating frequency bands where the first antenna is located, and further buffer the communication restriction parameters into a storage area in the controller, when the controller performs signal transmission on the first antenna, the controller reads the communication restriction parameters corresponding to the first operating frequency band where the first antenna is currently located from the storage area, so as to restrict the signal transmission of the first antenna. Further, when the current working frequency band of the first antenna is switched to another first working frequency band, the communication limitation parameter corresponding to the switched working frequency band is read in the storage area of the controller, so as to limit the signal transmission of the first antenna after the working frequency band is switched.

Taking a mobile phone as an example, a processor in the mobile phone obtains a maximum value of transmission power corresponding to one frequency point of a 2.4GHz frequency band and a 5GHz frequency band where two first antennas containing WiFi are respectively located, for example, the maximum value of transmission power of tx0 on the 2.4GHz frequency band is 11.5 mw, the maximum value of transmission power of tx0 on a b1 frequency point of the 5GHz frequency band is 8.5 mw, the maximum value of transmission power of tx1 on the 2.4GHz frequency band is 11.5 mw, the maximum value of transmission power of tx1 on a b2 frequency point of the 5GHz frequency band is 9.5 mw, and then the four maximum values of transmission power are put together in a communication restriction instruction and sent to respective control chips of the two first antennas of WiFi, so that after the control chips in the first antennas receive the communication restriction instruction, the four maximum values of transmission power are analyzed by a driving layer thereof and stored in a storage area in the control chips, when the first antenna needs to transmit signals, the maximum value of the transmitting power corresponding to the current working frequency band of the first antenna is read from the storage area of the control chip and transmitted to the modulation-demodulation module in the first antenna, for example, tx0 is currently in the 2.4GHz band, the control chip reads 11.5 mw from the memory area and transmits it to the tx0 modem module, and further for example, tx1 is currently at the b2 frequency point of the 5GHz band, the control chip reads 9.5 mw from the memory area and transmits it to the tx1 modem module, so that the modulation and demodulation module adjusts the transmitting power of the transmitting signal according to the maximum value of the transmitting power received by the modulation and demodulation module, thereby limiting the maximum transmit power of the transmit signal to be lower than the maximum transmit power value in the communication limit instruction, therefore, the purpose of limiting the transmission power is achieved, and the phenomenon that the radiation to a user is higher due to the fact that the transmission signal power is too high is avoided.

Furthermore, when the working frequency band of the first antenna is switched, the control chip reads the maximum value of the transmitting power corresponding to the working frequency band after the first antenna is switched from the storage area, for example, tx0 switches from 2.4GHz band to b1 frequency point of 5GHz band, then the control chip reads 8.5 mw from the storage area and transmits it to tx0 modem module, and further, for example, tx1 switches from b2 frequency point of 5GHz band to 2.4GHz band, then the control chip reads 11.5 mw from the storage area and transmits it to tx1 modem module, so that the modulation and demodulation module adjusts the transmitting power of the transmitting signal according to the maximum value of the transmitting power which is received again by the modulation and demodulation module, thereby limiting the maximum transmit power of the transmit signal to be lower than the maximum transmit power value in the communication limit instruction, therefore, the purpose of limiting the transmission power is achieved, and the phenomenon that the radiation to a user is higher due to the fact that the transmission signal power is too high is avoided.

It should be noted that, in this embodiment, there may be a case where any one of the first operating state of the first antenna, the second operating state of the second antenna, and the posture of the communication device relative to the user changes, based on which, it may be determined that the current use state of the communication device changes, at this time, the technical solution in this embodiment may be re-executed, for example, step 101 to step 103 may be re-executed to implement dynamic adjustment of signal transmission, so as to improve the real-time performance of adjustment.

Therefore, in the embodiment, the signal transmission of the radio frequency transmission path corresponding to the antenna is limited according to the use state of the communication device, so that the purpose of adjusting the radiation generated by the signal transmission can be achieved while the signal transmission of the radio frequency transmission path is ensured.

In an implementation manner, the parameter obtaining unit 1202 is specifically configured to: according to the current use state, obtaining a target limiting parameter group corresponding to the current use state in a preset limiting parameter list, wherein the target limiting parameter group comprises communication limiting parameters of different radio frequency transmitting paths corresponding to different working frequency bands on the communication module of the first communication type in the current use state;

In one implementation, the transmission limiting unit 1203 is specifically configured to: and sending a communication limiting instruction to a controller corresponding to the first working frequency band, wherein the communication limiting instruction comprises a communication limiting parameter corresponding to the first working frequency band, so that the controller corresponding to the first working frequency band triggers a radio frequency transmitting channel corresponding to the first working frequency band to limit signal transmission according to the communication limiting parameter.

It should be noted that, the specific implementation of each unit above may refer to the corresponding content in the foregoing, and is not detailed here.

Referring to fig. 13, a schematic structural diagram of a communication device provided in a third embodiment of the present application is shown, where the communication device may be a communication device that has an antenna and is capable of performing signal transmission, such as a mobile phone. The technical scheme in the embodiment is mainly used for adjusting radiation generated by signal transmission of the communication equipment.

Specifically, the communication device in this embodiment may include the following structure:

at least two first antennas 1301 required by a first communication type, wherein the first antennas 1301 are provided with radio frequency transmitting channels correspondingly;

at least two second antennas 1302 required by the second communication type, wherein the second antennas 1302 correspond to radio frequency transmission paths;

a processor 1303, configured to obtain a current usage state of the communication device, where the current usage state at least includes that a communication module of a first communication type is in an operating state; according to the current use state, obtaining communication limiting parameters of different radio frequency transmitting channels of different working frequency bands corresponding to the communication module of the first communication type in the current use state; in the current use state, if the communication module of the first communication type operates based on the first operating frequency band, the signal transmission of the radio frequency transmission path corresponding to the first operating frequency band is limited by the communication limitation parameter corresponding to the first operating frequency band.

It should be noted that the communication device may further include other components, such as a display, a touch screen, and an audio player, to implement corresponding functions.

As can be seen from the foregoing solution, in the communication device provided in the third embodiment of the present application, by obtaining the current use state of the communication device, since the current use state includes the operation state of the communication module of the first communication type, after the communication restriction parameter for the different rf transmission paths in the different operation frequency bands corresponding to the communication module of the first communication type is obtained according to the current use state, in the current use state, if the communication module of the first communication type operates based on the first operation frequency band, the signal transmission of the rf transmission path corresponding to the first operation frequency band is restricted through the communication restriction parameter corresponding to the first operation frequency band. Therefore, in this embodiment, signal transmission of the radio frequency transmission path corresponding to the antenna is limited according to the use state of the communication device, so that the purpose of adjusting radiation generated by signal transmission can be achieved while signal transmission of the radio frequency transmission path is guaranteed.

In one implementation, the communication device in this embodiment may further include the following structure, as shown in fig. 14:

It should be noted that, for the specific implementation of the processor in this embodiment, reference may be made to the corresponding contents in the foregoing, and details are not described here.

In specific implementation, a mobile phone is taken as an example to illustrate the embodiments in the present application in detail:

first, most mobile phones support Wifi MIMO mode in 5G communication mode, and in 5G products, the millimeter wave (millimeter wave) antennas of 2G, 3G, 4G or 5G, sub6, etc. are separated. In a Non-independent Networking (NSA) scenario, a scenario in which a main radio frequency such as LTE or 5G is transmitted with Wifi becomes complicated.

Therefore, in order to reduce radiation to the user while ensuring high throughput of WiFi communication, the embodiment of the present application proposes: based on the design of Hardware Hardware of the mobile phone, according to different WiFi communication scenes and different scenes that LTE, 2G, 3G, 4G or 5G and a Wireless Local Area Network (WLAN) transmit simultaneously, the transmitting power of Wifi is set to be the corresponding maximum transmitting power Plimit.

Specifically, in this embodiment, a limiting parameter list as shown in table1 is stored on the mobile phone, where the limiting parameter list includes 11 scenario WLAN power tables (i.e. the usage states in the foregoing): default Power table and Power table1-Power table 10. Each Power table corresponds to the maximum transmission Power of the two antennas tx0 and tx1 respectively corresponding to 5 different frequency bands, that is, the values recorded in each cell of table1, where the 5 different frequency bands are: 2.4 frequency band, 5GHz b1 frequency band, 5GHz b2 frequency band, 5GHz b3 frequency band, and 5GHz b4 frequency band.

TABLE1 list of limiting parameters

Wherein the values in table1 represent the unit of transmit power in db.

The Default Power table and Power table1-Power table10 in Table1 are described as follows:

default Power table: WLAN or dual Band simultaneousdbs (dual Band simultaneous) for WLAN, that is: only WiFi is in working state and the main rf antenna does not transmit continuously.

Wherein, the WLAN means: WiFi connects the access network, realizes directly connecting promptly WiFi direct with other cell-phones through WiFi, perhaps: the mobile phone is used as a network access hotspot through WiFi so as to facilitate other mobile phones to access the network;

DBS for WLAN refers to: WiFi is connected with a network access (station) and simultaneously performs Wifi direct connection, and the WiFi and the station work at 2.4GHz and 5G Hz respectively; or: WiFi is connected to the network and simultaneously used as Wifi hotspot services, and the WiFi and the Wifi hotspot services work at 2.4GHz and 5G Hz respectively.

Power table 1: WLAN and Top ANT TX, that is: wifi connection, and the top antenna (5G) is also continuously transmitting;

power table 2: WLAN and Bot ANT TX, that is: wifi connection, and the bottom antenna (e.g. LTE, 2G, 3G or 4G) is also transmitting continuously;

power table 3: hotspot and Top ANT TX, that is: the mobile phone is in Hotspot, and the top antenna also continuously transmits;

power table 4: hotspot and Bot ANT TX, that is: the mobile phone is used as Hotspot, and the bottom antenna also continuously transmits;

power table 5: WLAN SA and At Head, that is: wifi connection, meanwhile, VoWifi calls and the mobile phone is close to the head of the person;

power table 6: WLAN and Top ANT TX and At Head, that is: wifi connection, and the top antenna is also continuously transmitting, and meanwhile, the mobile phone is close to the head of a person;

power table 7: WLAN and Bot ANT TX and At Head, that is: the mobile phone is connected with the Wifi, the bottom antenna continuously transmits, and meanwhile the mobile phone is close to the head of a person, for example, the mobile phone is in a call through LTE, 2G, 3G or 4G or in a call through WiFi;

power table 8: WLAN SA BodyWorn, that is: wifi connection, and the mobile phone is close to the human body, such as placing a pocket;

power table 9: WLAN and Top ANT TX and body, that is: wifi connection, and the top antenna is also continuously transmitting, if uploading and downloading data, and meanwhile, the mobile phone is close to the human body;

power table 10: WLAN and Bot ANT TX and body word, that is: wifi connects to the bottom antenna is also continuously transmitting, and the cell phone is close to the human body simultaneously.

Based on the correspondence between the use status and the antenna operating frequency shown in table1, the mobile phone monitors the use status of its own operating scene, such as the operating status of the WiFi antenna, the operating status of the LTE, 2G, 3G, 4G, or 5G antenna, and the placement position of the mobile phone relative to the user, in real time, so as to determine a row of values corresponding to the current use status of the mobile phone in 11 statuses in table1, and based on this, after determining the frequency bands of the two WiFi antennas by frequency point detection on the mobile phone, the maximum value of the transmission power of each antenna respectively corresponding to WiFi is obtained in the determined row of values, for example, found in table 1: tx0 corresponds to 11.5 mw at 2.4GHz, tx1 corresponds to 9 mw at b2 band at 5GHz, and then after the two values are sent to the antenna chip in the form of instructions, the antenna chip analyzes the values through the driving layer and distributes the values to the modem module of each antenna for adjusting the transmission power of the transmission signal to avoid exceeding the values, thereby realizing power limitation.

Further, when the mobile phone finds that the use state, such as the working frequency band of the antenna or the scene, changes, the transmission power is adjusted again according to the above processing method.

Therefore, in the embodiment of the application, different power limit values are set according to different use scenes of the Wifi, so that an antenna without a human body approaching can keep a higher transmitting power upper limit, the throughput rate of signal transmission of the WiFi is guaranteed, and overhigh radiation is avoided.

In addition, in the embodiment of the application, different power limit values are also set for WiFi by distinguishing different scenes in which LTE, 2G, 3G, 4G, or 5G and WLAN transmit simultaneously. For example, in the NSA mode of 5G, LTE, 2G, 3G, 4G, or 5G and WiFi may be simultaneously transmitted, or only WiFi may be transmitted, so that after the distinction is made, by setting different power limit values, it can be ensured that when transmission power back-off is not needed more, a higher power upper limit can be provided on the premise of avoiding too high radiation, and the user experience of the mobile phone by the user is improved by improving the throughput of signal transmission.
