FIG. 2 is a schematic flowchart of a wireless communication method according to an embodiment of the present application. The method 200 may be performed by a terminal device, and the terminal device is connected to a first network and a second network at the same time. As shown in FIG. 2, Method 200 includes the following:

S210. The terminal device determines that the total equivalent transmission power of the first network and the second network corresponds to the maximum equivalent uplink proportion corresponding to the maximum transmission power. When the maximum equivalent uplink proportion is reached, the The specific absorption ratio SAR of the electromagnetic wave of the terminal equipment reaches a predetermined value;

Optionally, in the embodiment of the present application, the predetermined value of the SAR may be a value specified by a standard, and the SAR may be preset on the terminal device to indicate the requirements of the electromagnetic radiation intensity of the terminal device.

Optionally, in the embodiment of the present application, the first network and the second network may share a network device (specifically, an access network device), that is, the network device may simultaneously provide services for the first network and the second network. In this case, the network device can learn the uplink proportion of the first network and the second network; or the network devices (specifically, access network devices) of the first network and the second network can be independent. In this case, the terminal device The uplink proportion of the first network can be obtained, and the uplink proportion of the first network can be further reported to the network device of the second network, or vice versa, which is not limited in this embodiment of the present application.

Optionally, in the embodiment of the present application, the first network is the primary network, and the second network is the secondary network, that is, the connection between the terminal device and the first network is the primary connection, and the connection between the terminal device and the second network Supplementary connection.

By way of example and not limitation, the first network may be an LTE network, and the second network may be an NR network. In this case, the terminal device may be referred to as an EN-DC terminal; or, the first network may be an NR network, The second network may be an LTE network. In this case, the terminal device may be referred to as an NE-DC terminal. Hereinafter, the first network is an LTE network and the second network is an NR network as an example for description, but the embodiment of the present application Not limited to this.

Optionally, in the embodiment of the present application, the LTE network and the NR network may adopt a common antenna design, that is, the LTE network and the NR network may work in the same frequency band, therefore, the SAR brought by the LTE network and the NR network is equivalent, That is, the SAR value brought by the same transmission power of the LTE network and the NR network is the same. The SAR of the terminal equipment is the sum of the SAR of the LTE network and the NR network. The SAR is affected by the transmission power and the uplink ratio. Generally speaking, the higher the transmission power, the larger the SAR, the larger the uplink ratio and the larger the SAR. Therefore, the SAR of the terminal device can be adjusted by adjusting the transmission power or the uplink proportion.

Specifically, in the embodiment of the present application, the terminal device may determine the maximum equivalent uplink ratio when the total transmission power of the LTE network and the NR network is the maximum transmission power, specifically, the transmission power of the LTE network may be set Is the first transmission power, the transmission power of the NR network is set to the second transmission power, wherein the sum of the first transmission power and the second transmission power is the maximum transmission power; further, it can be measured Under the above transmission power, the maximum value of the local radiated electric field strength of the terminal equipment to the human body is recorded as E _1. If the maximum electric field strength corresponding to the SAR index specified in the standard is E ₀ , the terminal equipment can determine the maximum equivalent upstream occupation The ratio is E ₀ / E ₁ , that is, when the equivalent upstream share of the terminal device reaches the maximum equivalent upstream share, the SAR of the terminal device reaches a predetermined value. Further, the terminal device may report the maximum equivalent uplink share to the network device, so that the network device controls the uplink share of the LTE network or NR network so that the equivalent uplink share of the terminal device does not exceed This maximum equivalent upstream ratio can avoid the SAR over-standard problem of the terminal equipment.

It should be understood that, in the embodiment of the present application, when determining the maximum equivalent uplink ratio, the terminal device may also adjust the first transmission power and the second transmission power, as long as the sum of the two is the maximum transmission power. Yes, then test the maximum value of the local radiated electric field strength of the terminal device to the human body under different first transmission power and second transmission power, corresponding to the combination of different first transmission power and second transmission power Among the maximum values of the local radiated electric field strength, the largest one is selected as E1 for calculating the maximum equivalent upstream ratio.

Assuming that the total transmit power is P _max , the maximum value of the local radiated electric field intensity of the terminal device to the human body can be tested when the first transmit power is P _max / 2 and the second transmit power is P _max / 2, which is denoted as E _11. When the first transmit power is 2P _max / 3 and the second transmit power is P _max / 3, the maximum value of the local radiated electric field strength of the terminal device to the human body can be tested, which is denoted as E ₁₂ , or it can also be When the first transmit power is 3P _max / 4 and the second transmit power is P _max / 4, the maximum value of the local radiated electric field strength of the terminal device to the human body is tested, which is denoted as E _13. Further, it can be set at E ₁₁ , E ₁₂ and E ₁₃ select the maximum value as E1 for determining the maximum equivalent upstream ratio.

It should be understood that, in the embodiments of the present application, since the LTE network and the NR network can adopt a common antenna design, the contributions of the LTE network and the NR network to the SAR value at the same transmission power are generally the same, that is, E ₁₁ , The error between E ₁₂ and E ₁₃ is not large. In the actual test, it is sufficient to test only the maximum value of the local radiated electric field intensity of the terminal device to the human body in one case. For example, when only the first transmission power and the second transmission power are both 1/2 of the maximum transmission power, the maximum value of the local radiated electric field strength of the terminal device to the human body is used to calculate the maximum equivalent uplink ratio E1.

In the embodiment of the present application, the uplink and downlink ratio of the LTE network is usually statically or semi-statically configured, for example, 60%, 50%, 40%, 30%, 25% or 10%, etc. Therefore, the SAR of the LTE network Mainly affected by the transmission power, the uplink proportion of the NR network is usually semi-static or dynamic configuration, that is to say, the uplink and downlink ratio of the terminal equipment on the LTE network side is usually unchanged, while the uplink of the NR network side The proportion can be adjusted dynamically, and the window length of the upstream proportion can be any value. Therefore, the SAR value of the NR network is affected by the transmission power and the upstream proportion.

In the embodiment of the present application, when the terminal device accesses the LTE network, the terminal device can learn the uplink configuration information of the LTE network according to the system broadcast message of the LTE network, which includes the uplink and downlink configuration ratio of the LTE network, which can also be understood as The uplink proportion of LTE network.

In the embodiment of the present application, the terminal device may determine the current equivalent uplink ratio of the terminal device. For example, the terminal device may combine the first network and the second network according to the current uplink ratio of the first network and the second network. Second, the current transmit power of the network determines the current equivalent uplink share of the terminal equipment. It can be seen from the above description that the size of the SAR value of the terminal device is proportional to the transmission power and the uplink ratio. The larger the transmission power, the larger the SAR, the larger the uplink ratio, and the larger the SAR. The effective uplink share is greater than the maximum equivalent uplink share. For the terminal device, the current equivalent uplink share of the terminal device can be reduced by reducing the transmission power of the first network and / or the transmission power of the second network Ratio, so as to make it less than or equal to the maximum equivalent uplink ratio, so as to avoid the goal of SAR exceeding the standard of terminal equipment; for network equipment, you can reduce the uplink ratio of the first network and / or the second network In the manner of the uplink ratio, the current equivalent uplink ratio of the terminal equipment is reduced so as to be less than or equal to the maximum equivalent uplink ratio, so as to achieve the purpose of avoiding the SAR of the terminal equipment exceeding the standard.

In the following, with reference to specific embodiments, a specific implementation manner of the terminal device to avoid the SAR exceeding the standard will be described.

In the embodiment of the present application, the scheduling window length of the NR network is window, and the network device schedules the uplink proportion of the NR network in units of the window length, assuming that the transmission power in the window of the NR network is P ₂ , where P ₂ is linear Power value, the proportion of upstream is D _N2 . The transmission power of the LTE network is P ₁ , where P ₁ is also a linear power value, and the uplink proportion is D _N1 . Assuming that the maximum transmission power of the terminal device is P _max , the equivalent upstream proportion D _{en of} the terminal device in the window can be determined according to the following formula.

P ₁ * D _N1 + P ₂ * D _N2 = P _max * D _en formula (1)

P ₁ + P ₂ = P _max formula (2)

From the above formula (1) and formula (2) can be obtained:

D _en = D _N1 * P ₁ / P _max + D _N2 * P ₂ / P _max formula (3)

In order to avoid the SAR of the terminal equipment exceeding the standard, the equivalent upstream share D _{en of} the terminal equipment needs to be less than or equal to the maximum equivalent upstream share D _max , that is, D _N1 * P ₁ / P _max + D _N2 * P ₂ / P _max ≤D _max .

Since the uplink proportion of the LTE network is usually statically configured or semi-statically configured, that is, the uplink proportion of the LTE network is usually a fixed value, then the uplink proportion of the NR network can be controlled to make the equivalent uplink proportion of the terminal equipment less than Or equal to the maximum equivalent upstream share, that is, the upstream share of the second network needs to meet the following conditions:

D _N2 ≤ [D _max -D _N1 * (P ₁ / P _max )] / (1-P ₁ / P _max ) Formula (4)

Therefore, in order to avoid the problem that the SAR of the terminal device exceeds the standard, the network device needs to control it to satisfy the formula (4) when scheduling the uplink share of the NR network, that is, the maximum uplink share of the NR network is [D _max -D _N1 * (P ₁ / P _max )] / (1-P ₁ / P _max ).

Optionally, in a specific embodiment, if the transmission power of the first network and the transmission power of the second network are both 1/2 of the maximum transmission power, that is, P ₁ = P ₂ = P _max / 2, for example, both P ₁ and P ₂ are 23 dBm, and P _max is 26 dBm, then the maximum uplink proportion of the second network can be simplified to D _N2-max = 2D _max -D _N1 .

Optionally, in the embodiment of the present application, when the uplink proportion of the NR network is greater than the maximum proportion of the NR network, in this case, the terminal equipment may be at risk of SAR exceeding the standard, therefore, the terminal equipment may reduce the LTE network And the total transmit power of the NR network, optionally, the terminal device may also not send uplink data on a time unit capable of uplink transmission.

As an optional embodiment, if the connection between the terminal device and the LTE network is the main connection, the terminal device preferentially reduces the transmission power of the NR network. Optionally, in some cases, the terminal device may also disconnect from the NR network and only keep the connection with the LTE network, for example, if the degree of decrease in the transmission power of the NR network is greater than a certain threshold (for example, 3dB), In this case, it can be considered that the signal of the NR network is weak enough to support the communication connection of the terminal device on the NR network side. Therefore, the terminal device can disconnect from the NR network and only keep the connection with the LTE network.

Optionally, as another optional embodiment, if the connection between the terminal device and the NR network is the main connection, the terminal device may preferentially reduce the transmission power of the LTE network to reduce the SAR of the terminal device. Similarly, the terminal device can also disconnect from the LTE network and only keep the connection with the NR network. For example, if the reduction of the transmission power of the LTE network is greater than a certain threshold (for example, 3dB), in this case, it can be considered The weak signal of the LTE network is not enough to support the communication connection of the NR network side of the terminal device. Therefore, the terminal device can disconnect from the LTE network and only keep the connection with the NR network

Optionally, as yet another embodiment, if the uplink proportion of the NR network is greater than a certain threshold, and the threshold is greater than the maximum uplink proportion of the NR network, in this case, even if it can be considered that even if the transmit power of the NR network is reduced, the The SAR of the terminal device also has the risk of exceeding the standard. Therefore, the terminal device can choose to disconnect from the NR network and only keep the connection with the LTE network.

Optionally, in a specific embodiment, the terminal device reduces the transmission power of the first network and / or the second network, so that the reduced power of the first network and the second network The transmission power satisfies the following conditions: P ₁ × D _N1 + P ₂ × D _N2 ≤P _max × D _max , where P ₁ , P ₂ , and P _max are all linear power values.

That is to say, in the embodiment of the present application, when the SAR of the terminal device has a risk of exceeding the standard, the terminal device may choose not to use or reduce the use of the secondary network for data transmission, thereby reducing the contribution of the secondary network to the SAR of the terminal device the amount.

Similarly, for a network device, when the SAR of the terminal device is at risk of exceeding the standard, the network device may choose to reduce the uplink proportion of the secondary network, thereby reducing the contribution of the secondary network to the SAR of the terminal device.

Optionally, in the embodiment of the present application, the uplink proportion of the NR network is scheduled by the network device, or determined by the terminal device autonomously. That is, the uplink transmission of the terminal device may be uplink transmission scheduled based on the network device, or it may also be an uplink transmission initiated independently by the terminal device.

It should be noted that the uplink proportion in the embodiments of the present application may be regarded as the proportion of time domain resources that can be used for uplink transmission in a time unit. Alternatively, a time unit may be one or more subframes, or It is one or more time slots, or may be one or more mini time slots, etc., which is not limited in this embodiment of the present application. Suppose there are 10 time slots in a subframe. If 3 time slots in the 10 time slots can be used for uplink transmission and 7 time slots can be used for downlink transmission, the uplink proportion can be 30%.

It should be understood that in the embodiments of the present application, similar indicators such as the ratio of uplink and downlink resources (that is, the ratio of resources used for uplink transmission to resources used for downlink transmission in a time unit) may also be used to determine whether it is necessary to reduce the SAR, this embodiment of the present application does not limit this.

Above, with reference to FIG. 2, the wireless communication method of the embodiment of the present application is described in detail from the perspective of a terminal device, and below with reference to FIG. 3, the wireless communication method of the embodiment of the present application is described in detail from the perspective of a network device. The description on the network device side and the description on the terminal device side correspond to each other. For a similar description, refer to the foregoing embodiment.

FIG. 3 is a method of wireless communication according to another embodiment of the present application. The method 300 may be performed by a network device in the communication system shown in FIG. 1. The network device may provide services for both the first network and the second network. As shown in FIG. 3, the method 300 may include the following:

S310. The network device receives the maximum equivalent uplink ratio reported by the terminal device, where the maximum equivalent uplink ratio is when the total transmission power of the first network and the second network is the maximum transmission power. When the specific absorption ratio SAR of the electromagnetic wave of the terminal equipment reaches a predetermined value, the corresponding equivalent upstream ratio;

S320. The network device controls the uplink share of the first network and / or the uplink share of the second network, so that the equivalent uplink share of the terminal device is less than or equal to the maximum equivalent uplink Proportion.

For the determination method of the maximum equivalent uplink proportion, reference may be made to the related description in the foregoing embodiment, and details are not described herein again.

When the network device receives the maximum equivalent uplink share reported by the terminal device, it can control the uplink share of the first network and / or the uplink share of the second network to make the equivalent uplink share of the terminal device The ratio is less than or equal to the maximum equivalent uplink ratio, so that the SAR over-standard problem of the terminal device can be avoided.

It should be understood that, for the determination method of the equivalent uplink share of the terminal device herein, reference may be made to the determination method of the equivalent uplink share D _en of the terminal device in the foregoing embodiment, that is, the network device may determine the terminal device in a similar manner The equivalent uplink share of the network is further controlled by controlling the uplink share of the first network and / or the uplink share of the second network so that the equivalent uplink share of the terminal device is less than or equal to the maximum equivalent uplink share For brevity, I will not repeat them here.

It can be seen from formula (3) that the equivalent uplink share of the terminal equipment is proportional to the uplink share and transmit power of the first network, and the uplink share and transmit power of the second network. At least one of the uplink ratio and the transmission power, and the at least one of the second network's uplink ratio and the transmission power is proportional, can achieve the purpose of reducing the equivalent uplink ratio of the terminal device, and thus can reduce the SAR of the terminal device.

Hereinafter, the first network is an LTE network and the second network is an NR network as an example for description, but the embodiments of the present application are not limited thereto.

Optionally, in some specific cases, since the uplink proportion of the LTE network is usually statically configured or semi-statically configured, the network device can reduce the equivalent uplink proportion of the terminal device by adjusting the uplink proportion of the NR network Specifically, the uplink proportion of the NR network needs to satisfy the foregoing formula (4). Therefore, in order to avoid the problem that the SAR of the terminal device exceeds the standard, the network device needs to control it to satisfy the formula (4) when scheduling the uplink proportion of the NR network.

Optionally, the first network is a long-term evolution LTE network, the second network is a new wireless NR network, and the first network and the second network operate in the same frequency band.
