Detailed ways

The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings.

SAR is an index parameter that measures the electromagnetic radiation intensity of the terminal to the human body. It is generally used in the frequency band below 6 GHz. The standard has strict index requirements for the SAR value. Generally speaking, the higher the UE transmit power, the higher the SAR value, and the higher the proportion of the uplink time slot used, the higher the SAR. Therefore, high-power terminals (power>23dBm) have a higher SAR value than ordinary power terminals (power=23dBm). In order to prevent the SAR value from exceeding legal requirements, the proportion of the uplink time slot of the UE can be limited.

MPE (English: Maximum Permissible Emission, Chinese: Maximum Permissible Radiation) is another indicator parameter to measure the electromagnetic radiation intensity of the terminal to the human body. It is generally used in the frequency band above 6GHz, especially the millimeter wave frequency band. For millimeter wave terminals, in order to overcome the large propagation loss, a narrow transmit beam is generally used to concentrate the energy in the direction facing the base station. This also causes the millimeter wave terminal to easily form relatively strong electromagnetic radiation energy in a certain direction. In order to prevent the energy from harming human tissues, the International Standards Organization has also formulated corresponding standards to restrict the terminal from a certain direction when it is close to the human body. Radiant energy for a long time. The MPE is obtained by measuring the power density, and the average value of the power per unit area of the terminal in a certain direction during a period of time is used as the indicator. Generally speaking, the higher the terminal transmission power, the narrower the beam, and the higher the proportion of uplink transmission time, the higher the power density value.

Multi-frequency concurrency refers to the UE sending required data through electronic waves in multiple frequency bands, such as CA or dual connection. In a multi-frequency concurrency scenario, the UE may transmit the required data through electronic waves that cross 6 GHz (this value is only for illustration purposes, in actual communication scenarios, it can be determined according to the provisions of the standard protocol) two frequency bands. For example, in the dual connectivity (LTE+NR) mode, the two frequency bands that it may use may be less than 6 GHz and greater than 6 GHz, respectively. In this scenario, since SAR and MPE are respectively defined by different protocols, the UE cannot effectively ensure that SAR and MPE are not exceeded at the same time under multi-frequency concurrency.

Refer to Figure 1. Figure 1 is a schematic diagram of a network topology structure under multi-frequency concurrency provided by this application. As shown in Figure 1, the network topology structure includes: UE, PCell (English: Primary cell, Chinese: Primary cell), Scell (Secondary cell, Chinese: secondary cell). The UE is connected to the Pcell and the Scell respectively. Specifically, the UE can be connected to the Pcell through electromagnetic waves less than 6 GHz, and the UE can be connected to the Scell through electromagnetic waves greater than 6 GHz. Of course, in practical applications, the UE can also be connected to the Pcell through electromagnetic waves greater than 6 GHz, and the UE can be connected to the Scell through electromagnetic waves less than 6 GHz. Of course, in practical applications, the above-mentioned distinguishing frequency point may not be 6 GHz.

In this possible example, the acquisition of the radiation parameter specifically includes the following steps: acquiring the current maximum value of the communication parameter of the UE, and determining that the maximum value of the communication parameter corresponds to the mapping relationship between the maximum value of the communication parameter and the radiation parameter Radiation parameters.

In this possible example, when the UE does not configure the communication parameters issued by the network device or the feedback message includes the configuration suggestion, the total radiation of the UE is determined by the UE in real time. monitor.

In this possible example, when the real-time monitoring of the total radiation exceeds the radiation index value, the value of the communication parameter under concurrent multi-frequency band is reduced by the UE.

In this possible example, reducing the value of the communication parameter under the concurrent multi-band by the UE specifically includes the following steps: deactivating the Scell, reducing the value of the communication parameter of the Pcell, or reducing the value of the communication parameter of the Scell.

In this possible example, the communication parameters include: UE transmit power and/or UE uplink time slot ratio.

Wherein, the radiation parameter may specifically include at least one of the following: SAR, MPE. The aforementioned current cell may be a Pcell.

In step S202, the user equipment UE is concurrently using multiple frequency bands, and the UE sends the communication parameters or radiation parameters of the current cell to the network equipment, and the current cell is the primary cell Pcell.

In this possible example, sending, by the UE, the communication parameters or radiation parameters of the current cell to the network device specifically includes: the UE receives an inquiry request sent by the network device, and according to the inquiry request, the communication parameter or The radiation parameters are sent to the network device.

Among them, SARmax is the value of the SAR index; SAR1 is the current actual SAR value, MPEmax is the MPE index value; MPE1 is the current actual MPE value.

In this possible example, configuring, by the UE, the communication parameters of the primary cell Pcell and the communication parameters of the secondary cell Scell according to the radiation parameters specifically includes: keeping the values of the communication parameters of the Pcell different according to the margin of the radiation parameters. Change, add the communication parameter of the secondary cell Scell; or reduce the value of the communication parameter of the Pcell according to the margin of the radiation parameter, and add the communication parameter of the secondary cell Scell.

Take a practical example to illustrate, the implementation process is shown in Figure 2b;

Step S201a: The network device sends an inquiry message to the UE;

Step S201b: The UE monitors the maximum transmit power of the current cell, and sends the maximum transmit power to the network device;

Step S201c: The network device queries and obtains the radiation parameter corresponding to the maximum value of the transmission power according to the preset mapping relationship between the transmission power and the radiation parameter.

The above-mentioned preset mapping relationship between transmit power and radiation parameters can be set by the manufacturer at the factory.

In a possible example, if the network device determines not to add a Scell, the network device determines to keep the value of the communication parameter of the Pcell unchanged. The specific implementation manner may be, for example, when the network device determines not to add the Scell, the UE transmit power of the Pcell and/or the UE uplink time slot ratio remain unchanged. This situation is generally the case where the current radiation margin of the UE is zero. If Scell is added in this case, the UE may not meet the set conditions and cause the total radiation of the UE to exceed the standard (ie SAR ₁ /SAR _max +MPE ₁ /MPE _max ＞ 1) Therefore, the Pcell directly assumes that no Scell is added, and the value of the communication parameter of the Pcell remains unchanged.

In a possible example, if the network device determines to add a Scell, the network device configures the communication parameters of the Pcell and the communication parameters of the Scell according to the radiation parameters and meets the set conditions.

The above setting condition may be: the setting condition is: SAR ₁ /SAR _max +MPE ₁ /MPE _max ≤1;

The foregoing communication parameter may be multiple. For example, in an optional embodiment, the foregoing communication parameter may be: UE transmit power. In another optional embodiment, the aforementioned communication parameter may also be: UE uplink time slot ratio. In yet another optional embodiment, the aforementioned communication parameters may be: UE transmit power and UE uplink time slot ratio.

Optionally, the configuration of the communication parameters of the Pcell and the communication parameters of the Scell by the aforementioned network device according to the radiation parameter may specifically include any one of the following situations:

Case A: Keep the value of the communication parameter of the Pcell unchanged according to the radiation parameter, and add the communication parameter of the secondary cell Scell;

For the above situation A, the realizing scenario is mainly the situation where the radiation margin is not zero at this time, which can be specifically divided into the following ways:

Method A1. When the radiation parameter margin is greater than zero, keep the value of the Pcell communication parameter unchanged, and add the Scell communication parameter.

For the method A1, it is mainly for the case where the radiation parameter margin is relatively large. At this time, because the radiation margin is relatively large, the radiation margin is sufficient to ensure that the communication parameters of the Scell are added to still ensure that the above setting conditions are met, so the Pcell may not be changed. For communication parameters, just add the communication parameters of Scell directly.

Case B: Decrease the value of the communication parameter of the Pcell according to the radiation parameter, and add the communication parameter of the secondary cell Scell.

For the above case B, the radiation margin of the realized scene may be zero, and the radiation margin may also be greater than zero. Specifically, it can be divided into the following ways:

Method B1. When the radiation parameter margin is greater than zero, reduce the value of the Pcell communication parameter and add the Scell communication parameter.

For method B1, the radiation parameter margin is small. Although the radiation parameter margin is greater than zero, the setting conditions cannot be met after adding Scell. At this time, it is necessary to reduce the value of the Pcell communication parameter to increase the radiation. Margin, so as to ensure that the increased radiation margin can meet the requirements of adding Scell.

For the embodiment B1 specific scenario which may be implemented, assuming communications band is less than 6GHz Pcell, Scell communications band is more than 6GHz, Pcell determined SAR margin of the UE (SAR margin _{_{= 1-SAR 1 / SAR max}} ) is greater than Zero. At this time, when Pcell determines to keep Pcell unchanged, add Scell communication parameters, which cannot meet the set conditions. At this time, Pcell determines that the priority or weight of the service carried by the Scell is higher than the priority or importance of the service carried by Pcell. At this time, the Pcell reduces the value of its own communication parameter, that is, the Pcell reduces the service carried by itself, and adds the communication parameter of the Scell, that is, the Pcell increases the service carried by the Scell.

Method B2. When the radiation parameter margin is equal to zero, reduce the value of the Pcell communication parameter and add the Scell communication parameter.

For the method B2, it is mainly for the case of no radiation parameter margin. At this time, although the radiation parameter margin is equal to zero, if the value of the Pcell communication parameter remains unchanged at this time, Scell cannot be added, but the service at this time needs to add Scell. At this time, it is necessary to reduce the value of the Pcell communication parameter to increase the radiation margin, so as to ensure that the increased radiation margin can meet the requirements of adding Scell.

For method B2, the specific scenario of its implementation can be as follows. It is assumed that the communication frequency band of Pcell is less than 6GHz, and the communication frequency band of Scell is greater than 6GHz. Pcell determines that the SAR margin of the UE is equal to zero. Obviously, if the communication parameters of Pcell are guaranteed at this time When Scell is added without changing the value, the set condition cannot be satisfied. Therefore, the Pcell needs to reduce the value of its own communication parameters. For example, in an optional embodiment, when the Pcell determines that the priority or weight of the service carried by the Scell is higher than the priority or importance of the service carried by the Pcell, The Pcell reduces the value of its own communication parameter, that is, the Pcell reduces the service carried by itself, and adds the communication parameter of the Scell, that is, the Pcell increases the service carried by the Scell.

Referring to Fig. 3a, the embodiment shown in Fig. 3a provides a method for configuring communication parameters under concurrent multi-frequency bands. The radiation parameters in this method are SAR as an example. Of course, in practical applications, other radiation parameters can also be used, such as MPE. The communication parameter in this embodiment takes the maximum transmission power as an example. Of course, in practical applications, the above communication parameter may also be the uplink time slot ratio. The method shown in Figure 3a is implemented in the network topology shown in Figure 1, where the working frequency band of the Pcell shown in Figure 1 can be less than 6 GHz, and the working frequency band of the Scell shown in Figure 1 can be greater than 6GHz, the method is shown in Figure 3a, including the following steps:

Step S301: When the network device (the network device to which the Pcell belongs) determines that the UE is in multi-frequency concurrency, it sends an inquiry message to the UE;

Step S302: After receiving the inquiry message, the UE queries the maximum transmit power of the current cell (Pcell), determines the SAR ₁ corresponding to the maximum transmit power according to the mapping relationship between power and SAR, and sends the SAR ₁ to the Pcell.

Step S303: After receiving the SAR ₁ , the network device determines whether the SAR margin is greater than zero, if not greater than zero, and executes step S304a, if greater than zero, executes step S304b.

The above SAR margin = 1-SAR ₁ /SAR _max .

Step S304a: The network device chooses not to add Scell;

Step S304b: The network device keeps the maximum transmit power of Pcell unchanged, adds the maximum transmit power of Scell and meets the set conditions (the above set conditions can be referred to the description of the embodiment shown in Figure 2a, which will not be repeated here)

Optionally, the above step S304a may also be replaced by step S304c in some specific cases. The above specific cases include but are not limited to: when the UE needs to use a large bandwidth of the Scell in the frequency band above 6 GHz when providing a high rate. Of course, the above specific situation can also be when other UEs need frequency bands above 6 GHz. For example, the priority of services in the frequency band above 6 GHz is higher than the priority of services in the frequency band below 6 GHz; of course, in practical applications, it can also be Other specific situations, such as user settings, pre-configuration, etc.

Step S304c: The network device reduces the maximum transmission power of the Pcell, adds the maximum transmission power of the Scell and satisfies the set conditions.

Optionally, the above step S304b can also be replaced by step S304d.

Step S304d: The network device reduces the maximum transmission power of the Pcell, adds the maximum transmission power of the Scell and satisfies the set conditions.

For the above-mentioned step S304d, the situation mainly occurs when the SAR margin is greater than zero, but relatively small, that is, if the maximum transmit power of Pcell is kept unchanged, and the maximum transmit power of Scell is directly added, the set condition cannot be met, and it needs Control the Pcell to give up part of the transmission power to borrow to the Scell to ensure that the maximum transmission power of the Scell is added to meet the set conditions.

The technical solution Pcell provided in this application solicits the opinions of the UE before configuring the Scell. The Pcell can be used to ensure that the UE’s SAR and MPE joint indicators do not exceed the standard (that is, meet the set conditions), and it is no longer necessary for the UE to monitor communication parameters and other factors in real time. It can achieve more power saving, so it has more power saving, and considers the combination of SAR and MPE to avoid excessive radiation and improve the safety of UE.

Referring to FIG. 3b, the embodiment shown in FIG. 3b provides a communication parameter configuration method. The radiation parameter in the method is MPE as an example. Of course, in practical applications, other radiation parameters, such as SAR, can also be used. The communication parameter in this embodiment is taken as an example of the upstream time slot ratio. Of course, in practical applications, the above communication parameter may also be the maximum transmission power. The method shown in Figure 3b is implemented in the network topology shown in Figure 1, where the working frequency band of the Pcell shown in Figure 1 can be greater than 6 GHz, and the working frequency band of the Scell shown in Figure 1 can be less than 6GHz, the method is shown in Figure 3b, including the following steps:

Step S301b: When the network device (the network device to which the Pcell belongs) determines that the UE is in multi-frequency concurrency, it sends an inquiry message to the UE;

Step S302b. After receiving the inquiry message, the UE queries the maximum transmit power of the current cell (Pcell), determines the MPE ₁ corresponding to the maximum transmit power according to the mapping relationship between power and MPE, and the UE determines the Scell according to the margin of the MPE Configuration proposal; UE sends the configuration proposal to Pcell.

The above-mentioned MPR margin = 1-MPE ₁ /MPE _max .

The above configuration suggestions include but are not limited to: not adding Scell or adding Scell. Of course, when adding a Scell, the configuration suggestion may also include: the proportion of the uplink time slot of the Scell or the proportion of the uplink time slot of the Pcell.

Step S303b: The network device configures the Scell according to the configuration proposal.

The technical solution Pcell provided in this application solicits the opinions of the UE before configuring the Scell, and then executes the configuration recommendation according to the configuration recommendation reported by the UE, so that the Pcell can be used to ensure that the UE's SAR and MPE joint indicators do not exceed the standard (that is, meet the set conditions) , For UE, it is no longer necessary to monitor communication parameters and other factors in real time, which can achieve more power saving, so it has more power saving, and considers the combination of SAR and MPE to avoid excessive radiation and improve the safety of UE.

Referring to Fig. 4a, the embodiment shown in Fig. 4a provides a communication parameter configuration method. The radiation parameters in the method are SAR as an example. Of course, in practical applications, other radiation parameters, such as MPE, can also be used. The communication parameter in this embodiment takes the maximum transmission power as an example. Of course, in practical applications, the above communication parameter may also be the uplink time slot ratio. The method shown in Figure 4a is implemented in the network topology shown in Figure 1, where the working frequency band of the Pcell shown in Figure 1 can be less than 6 GHz, and the working frequency band of the Scell shown in Figure 1 can be greater than 6GHz, the method is shown in Figure 4a, including the following steps:

Step S401: When the network device (the network device to which the Pcell belongs) determines that the UE is in multi-frequency concurrency, it sends a Scell configuration message to the UE, where the configuration message includes: the maximum transmission power of the Scell;

Step S402: The UE queries the maximum transmit power of the current cell, determines the SAR ₁ corresponding to the maximum transmit power according to the mapping relationship between power and SAR, and when the SAR margin is determined to be zero, sends a rejection message to the network device, and the rejection message carries SAR margin is zero;

Step S403-1: The network device receives the rejection message and does not add Scell according to the rejection message.

Step S403-2: The network device receives the rejection message, reduces the maximum transmission power of the Pcell and satisfies the set conditions, and sends an Scell configuration message to the UE again to inform the UE.

In the technical solution provided by this application, after configuring the Scell, the Pcell receives the rejection message sent by the UE, and then adjusts the communication parameters of the Scell according to the rejection message. In this way, the Pcell can be used to ensure that the UE’s SAR and MPE joint indicators do not exceed the standard (that is, meet the set conditions ), for the UE, there is no need to monitor communication parameters and other factors in real time, which can achieve more power saving, so it has more power saving, and considers the combination of SAR and MPE to avoid excessive radiation and improve the safety of UE .

Referring to Fig. 4b, the embodiment shown in Fig. 4b provides a communication parameter configuration method. The radiation parameters in the method are SAR as an example. Of course, in practical applications, other radiation parameters, such as MPE, can also be used. The communication parameter in this embodiment takes the maximum transmission power as an example.
