[0151] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0152] Step S2101: The terminal determines whether to send first information to the network device based on the terminal's transmission power and / or duty cycle coefficient.

[0153] In some embodiments, the transmit power of the terminal refers to the actual transmit power of the terminal in the corresponding frequency band. In some embodiments, the operating frequency band of the terminal includes a first frequency band and a second frequency band, and the transmit power of the terminal includes the transmit power of the terminal in the first frequency band and the transmit power of the terminal in the second frequency band. Optionally, the first frequency band may be FR1 and the second frequency band may be FR2.

[0154] In some embodiments, the duty cycle coefficient of the terminal refers to the duty cycle coefficient of the terminal in the corresponding frequency band. In some embodiments, the terminal operating frequency band includes a first frequency band and a second frequency band, and the duty cycle coefficient of the terminal includes the duty cycle coefficient of the terminal in the first frequency band and the duty cycle coefficient of the terminal in the second frequency band.

[0155] In some embodiments, the duty cycle coefficient of the terminal refers to the ratio between the duty cycle corresponding to the actual transmit power of the terminal in the corresponding frequency band and the duty cycle corresponding to the maximum transmit power corresponding to the restriction requirement. Optionally, the restriction requirement may be a SAR restriction requirement, an EIRP restriction requirement, or other restriction requirement, which is not limited in the embodiments of the present disclosure. Optionally, the SAR restriction requirement and the EIRP restriction requirement both refer to not exceeding the safety requirements of the object.

[0156] In some embodiments, the object refers to a user, an object using a terminal, a human body, etc., which is not limited in the embodiments of the present disclosure.

[0157] In some embodiments, the SAR limit requirement and the EIRP limit requirement are both fixed values. Optionally, the SAR limit requirement and the EIRP limit requirement are both agreed upon by the communication protocol or agreed upon in other ways, which are not limited in the embodiments of the present disclosure.

[0158] In some embodiments, if the SAR value of the terminal does not exceed the SAR limit requirement, it means that the impact of the terminal's SAR on the first object does not exceed the safety requirement; and if the SAR value of the terminal exceeds the SAR limit requirement, it means that the impact of the terminal's SAR on the first object exceeds the safety requirement.

[0159] Optionally, if the transmit power of the terminal does not exceed the transmit power corresponding to the SAR limit requirement, it means that the impact of the transmit power of the terminal on the first object does not exceed the safety requirements, and if the transmit power of the terminal exceeds the transmit power corresponding to the SAR limit requirement, it means that the impact of the transmit power of the terminal on the first object exceeds the safety requirements.

[0160] In some embodiments, if the transmission power of the terminal does not exceed the transmission power corresponding to the EIRP limit requirement, it means that the impact of the terminal's transmission power on the first object does not exceed the safety requirements, and if the transmission power of the terminal exceeds the transmission power corresponding to the EIRP limit requirement, it means that the impact of the terminal's EIRP on the first object exceeds the safety requirements.

[0161] In some embodiments, the terminal may determine whether to send the first information to the network device based on the terminal's transmit power. Alternatively, the terminal may determine whether to send the first information to the network device based on the terminal's transmit power and a duty cycle coefficient. Alternatively, the terminal may determine whether to send the first information to the network device based on the terminal's duty cycle coefficient.

[0162] In some embodiments, whether the terminal sends the first information to the network device includes: the terminal sends the first information to the network device, or the terminal does not send the first information to the network device.

[0163] In some embodiments, a risk coefficient is determined based on the transmission power and / or duty cycle coefficient of the terminal, and if the risk coefficient is greater than a risk threshold, it is determined to send the first information to the network device.

[0164] In some embodiments, a risk coefficient is determined based on the transmission power and / or duty cycle coefficient of the terminal, and if the risk coefficient is not greater than a risk threshold, it is determined not to send the first information to the network device.

[0165] In some embodiments, the risk threshold is defined by a communication protocol, configured by a network device, or set in another manner. In some embodiments, the risk coefficient is used to indicate the degree of electromagnetic radiation generated by the terminal. A higher risk coefficient indicates more electromagnetic radiation generated by the terminal and a higher safety impact on the first object. A lower risk coefficient indicates less electromagnetic radiation generated by the terminal and a lower safety impact on the first object.

[0166] In some embodiments, the terminal determines the risk factor based on the terminal's transmit power on the first frequency band, the terminal's transmit power on the second frequency band, the duty cycle coefficient on the first frequency band, and the duty cycle coefficient on the second frequency band.

[0167] In an embodiment of the present disclosure, the terminal can obtain the transmission power on the first frequency band and the transmission power on the second frequency band, and can also obtain the duty cycle coefficient on the first frequency band and the duty cycle coefficient on the second frequency band. The terminal can then calculate the risk coefficient for the obtained transmission power and duty cycle coefficient, and then determine whether it exceeds the risk threshold based on the risk coefficient.

[0168] In some embodiments, a first product of the terminal's transmission power on a first frequency band and a duty cycle coefficient on the first frequency band is obtained, a second product of the terminal's transmission power on a second frequency band and a duty cycle coefficient on the second frequency band is obtained, and the sum of the first product and the second product is determined as a risk coefficient.

[0169] Optionally, the terminal determines the ratio of the duty cycle corresponding to the terminal's transmit power in the first frequency band to the duty cycle corresponding to the terminal's maximum transmission that meets SAR limit requirements in the first frequency band as the duty cycle coefficient in the first frequency band.

[0170] Optionally, the terminal determines the ratio of the duty cycle corresponding to the terminal's transmit power in the second frequency band to the duty cycle corresponding to the terminal's maximum transmission that meets SAR limit requirements in the second frequency band as the duty cycle coefficient in the second frequency band.

[0171] Optionally, the risk coefficient is expressed using the following formula: C = A*P 实发 / P 限值 +B*EIRP 实发 / EIRP 限值 , where C is the risk factor, P 实发 Indicates the actual transmitted power of the terminal in the first frequency band, EIRP 实发 Indicates the EIRP actually transmitted by the terminal in the second frequency band, P 限值 Indicates the maximum transmit power of the terminal when it meets the SAR limit requirements in the first frequency band. The limit may be different for different first frequency bands; EIRP 限值 Indicates the maximum transmit power of the terminal when it meets the MPE (Maximum Permissible Exposure) limit requirement in the second frequency band. The limit can be different for different second frequency bands. A and B are the coefficients corresponding to the duty cycle. A is the current P 实发 Duty cycle / P 限值 The corresponding duty cycle, B is the current EIRP 实发 Duty cycle / EIRP 限值 The corresponding duty cycle.

[0172] In some embodiments, the present disclosure does not limit the name of the risk coefficient, which may be, for example, a monitoring coefficient, a risk monitoring value, a radiation value, an electromagnetic radiation value, etc.

[0173] In some embodiments, the present disclosure does not limit the name of the risk threshold, which may be, for example, a reference threshold, a monitoring threshold, a radiation threshold, etc.

[0174] In some embodiments, the terminal determines the risk factor based on the terminal's transmit power in the first frequency band and the terminal's transmit power in the second frequency band. In the disclosed embodiment, the terminal's main safety impact on the first object is due to its transmit power, so the terminal can determine whether to send the first information based on its own transmit power.

[0175] In some embodiments, the sum of the transmit power of the terminal in the first frequency band and the transmit power in the second frequency band is determined as the risk coefficient.

[0176] Alternatively, C=P 实发 / P 限值 +EIRP 实发 / EIRP 限值 , where C is the risk factor, P 实发 Indicates the actual transmitted power of the terminal in the first frequency band, EIRP 实发 Indicates the EIRP actually transmitted by the terminal in the second frequency band, P 限值 Indicates the maximum transmit power of the terminal when it meets the SAR limit requirements in the first frequency band. The limit may be different for different first frequency bands; EIRP 限值 Indicates the maximum transmit power of the terminal when the MPE limit requirement is met in the second frequency band. The limit can be different for different second frequency bands.

[0177] Step S2102: The terminal sends first information to the network device.

[0178] In some embodiments, the network device receives the first information sent by the terminal. In some embodiments, the terminal sends the first information. In some embodiments, the network device receives the first information.

[0179] In some embodiments, when determining that the first information needs to be sent to the network device, the terminal sends the first information to the network device.

[0180] In some embodiments, the first information indicates that the terminal presents a security risk, where the security risk refers to a safety impact on the first subject during operation of the terminal. In some embodiments, the security risk may also refer to an impact on the first subject's body during operation of the terminal. Alternatively, the terminal may also refer to electromagnetic radiation exceeding a specified level generated by the terminal during operation of the first subject.

[0181] In some embodiments, the first information may also be understood as indicating that there is a safety hazard in the terminal, or that the terminal does not meet working requirements, or that the terminal's transmission power does not meet requirements.

[0182] It should be noted that the disclosed embodiments use the example of first information indicating that a terminal presents a security risk. In another embodiment, the first information indicates that the terminal's risk factor is greater than a risk threshold. This risk factor or risk threshold is similar to that in the above embodiment and will not be further described here. Alternatively, the first information indicates the terminal's own risk factor.

[0183] In other embodiments, the first information is used to indicate that the terminal has a radiation hazard.

[0184] In other embodiments, the first information is used to indicate that the electromagnetic radiation of the terminal exceeds a radiation threshold.

[0185] In another embodiment, the first information is used to indicate that the transmit power and / or duty cycle of the terminal needs to be adjusted.

[0186] In another embodiment, the first information is used to indicate that parameters of the terminal need to be adjusted.

[0187] Optionally, the first information carries a risk factor, which indicates that the terminal has a security risk. Optionally, the first information has one bit. If the bit is 1, it indicates that the terminal has a security risk, or that the terminal's risk factor is greater than a risk threshold. Alternatively, the terminal's transmit power and / or duty cycle needs to be adjusted. Alternatively, if the bit is 0, it indicates that the terminal has a security risk, or that the terminal's risk factor is greater than a risk threshold. Alternatively, the terminal's transmit power and / or duty cycle needs to be adjusted.

[0188] In some embodiments, the first information further includes second information, where the second information is used to indicate that the transmit power and / or duty cycle coefficient of the terminal is adjusted according to the first rule.

[0189] In the embodiment of the present disclosure, when the terminal determines that there is a security risk, the terminal will determine the adjustment method according to the first rule, and then send a second message to the network device, instructing the network device to adjust the transmission power and / or duty cycle coefficient according to the second information.

[0190] In some embodiments, the first rule includes at least one of the following:

[0191] (1) Reduce the terminal's transmit power and / or duty cycle on the corresponding frequency band according to the frequency band priority.

[0192] In some embodiments, each frequency band has a corresponding priority, and the transmit power and / or duty cycle coefficient of the terminal on the corresponding frequency band is reduced in order of priority from high to low or from low to high.

[0193] In some embodiments, the terminal preferentially reduces the transmit power and / or duty cycle coefficient on the frequency band with the highest priority, then reduces the transmit power and / or duty cycle coefficient on the frequency band with the second highest priority, and so on, reducing the transmit power and / or duty cycle coefficient on frequency bands with other priorities. In some embodiments, reducing the transmit power and / or duty cycle coefficient includes reducing the transmit power, reducing the duty cycle coefficient, or reducing the transmit power and duty cycle coefficient.

[0194] In some embodiments, reducing the duty cycle coefficient includes reducing the duty cycle corresponding to the transmission power of the terminal in the corresponding frequency band.

[0195] In some embodiments, the transmit power and / or duty cycle of the terminal on the corresponding frequency band may be reduced multiple times according to the priority of the frequency band until the terminal no longer poses a security risk. In some embodiments, the transmit power and / or duty cycle of the terminal on the corresponding frequency band may be reduced multiple times according to the priority of the frequency band until the risk factor of the terminal is less than a risk threshold.

[0196] (2) Prioritize reducing the terminal's transmit power and / or duty cycle in frequency bands with smaller PHRs.

[0197] In some embodiments, the terminal preferentially reduces the transmit power and / or duty cycle of the terminal on the frequency band with the smallest PHR. It then reduces the transmit power and / or duty cycle of the terminal on the frequency band with the PHR next to the smallest PHR. Similarly, it reduces the transmit power and / or duty cycle of the terminal on frequency bands with other PHRs.

[0198] In some embodiments, the transmit power and / or duty cycle of the terminal on a frequency band with a smaller PHR may be reduced multiple times until the terminal no longer poses a security risk. In some embodiments, the transmit power and / or duty cycle of the terminal on a frequency band with a smaller PHR may be reduced multiple times until the risk factor of the terminal is less than a risk threshold.

[0199] (3) Prioritize reducing the terminal's transmit power and / or duty cycle in frequency bands with larger PHRs.

[0200] In some embodiments, the terminal preferentially reduces the transmit power and / or duty cycle of the terminal on the frequency band with the largest PHR. It then reduces the transmit power and / or duty cycle of the terminal on the frequency band with the second-highest PHR. This process is repeated until the transmit power and / or duty cycle of the terminal on other frequency bands with the highest PHR are reduced.

[0201] In some embodiments, the transmit power and / or duty cycle of the terminal on a frequency band with a larger PHR may be reduced multiple times until the terminal no longer poses a security risk. In some embodiments, the transmit power and / or duty cycle of the terminal on a frequency band with a larger PHR may be reduced multiple times until the risk factor of the terminal is less than a risk threshold.

[0202] (4) Prioritize reducing the terminal's transmit power and / or duty cycle in frequency bands with better signal-to-noise ratios.

[0203] In some embodiments, the terminal preferentially reduces the transmit power and / or duty cycle of the terminal on the frequency band with the best signal-to-noise ratio. It then reduces the transmit power and / or duty cycle of the terminal on the frequency band with the second-highest signal-to-noise ratio. This process continues in this manner, before reducing the transmit power and / or duty cycle of the terminal on frequency bands with other signal-to-noise ratios.

[0204] In some embodiments, the transmit power and / or duty cycle of the terminal on a frequency band with a good signal-to-noise ratio may be reduced multiple times until the terminal no longer poses a security risk. In some embodiments, the transmit power and / or duty cycle of the terminal on a frequency band with a good signal-to-noise ratio may be reduced multiple times until the risk factor of the terminal is less than a risk threshold.

[0205] (5) Prioritize reducing the terminal's transmit power and / or duty cycle in frequency bands with poor signal-to-noise ratios.

[0206] In some embodiments, the terminal preferentially reduces the transmit power and / or duty cycle of the terminal on the frequency band with the worst signal-to-noise ratio. It then reduces the transmit power and / or duty cycle of the terminal on the frequency band with the second-worst signal-to-noise ratio. This process is repeated for frequency bands with other signal-to-noise ratios.

[0207] In some embodiments, the transmit power and / or duty cycle of a terminal on a frequency band with a poor signal-to-noise ratio may be reduced multiple times until the terminal no longer poses a security risk. In some embodiments, the transmit power and / or duty cycle of a terminal on a frequency band with a poor signal-to-noise ratio may be reduced multiple times until the terminal's risk factor is less than a risk threshold.

[0208] In some embodiments, the first information further includes a maximum transmit power when a SAR limit requirement is met and / or a maximum transmit power when an MPE limit requirement is met.

[0209] In an embodiment of the present disclosure, the terminal directly sends the maximum transmit power when the SAR limit requirement is met and / or the maximum transmit power when the MPE limit requirement is met to the network device. The network device can then determine that the terminal has a security risk based on the first information reported by the terminal, and then adjust the transmit power and / or duty cycle coefficient of the terminal based on the maximum transmit power when the SAR limit requirement is met and / or the maximum transmit power when the MPE limit requirement is met, so that the adjusted terminal no longer has a security risk.

[0210] Step S2103: The network device determines the third information according to the first rule.

[0211] In some embodiments, the third information is used to instruct adjustment of the transmit power and / or duty cycle of the terminal; the third information is determined by the network device according to the first rule.

[0212] In some embodiments, the first rule includes at least one of the following:

[0288] The trigger condition may be as follows: monitoring whether the following formula is greater than a preset value. In one embodiment, the preset value is 1. If so, a report is triggered:

[0289] A*P 实发 / P 限值 +B*EIRP 实发 / EIRP 限值

[0290] Among them, P 实发 Indicates the actual transmitted power of the terminal in the FR1 frequency band

[0291] EIRP 实发 Indicates the EIRP actually transmitted by the terminal in the FR2 frequency band

[0292] P 限值 Indicates the maximum transmit power of the terminal when it meets the SAR limit requirements in the FR1 frequency band. The limit can be different for different FR1 frequency bands.

[0298] 3. According to the signal-to-noise ratio of each frequency band, such as giving priority to reducing the transmission power or duty cycle of the frequency band with poor signal-to-noise ratio, or giving priority to reducing the transmission power or duty cycle of the frequency band with good signal-to-noise ratio

The base station performs power control on the terminal based on the information reported by the terminal.

[0300] In one embodiment, the terminal reports P 限值 and EIRP 限值 When the terminal reports that there is a human safety risk, the base station will 限值 and EIRP 限值， The current transmit power of the terminal can be used to determine how to reduce transmit power to better balance human safety requirements and communication performance requirements. For example, whether to reduce the power or duty cycle of only the FR1 or FR2 band, or to reduce the power or duty cycle of both FR1 and FR2 simultaneously, to ensure that the target power after the reduction meets the following conditions:

[0301] A*P 目标 / P 限值 +B*EIRP 目标 / EIRP 限值 Less than or equal to the preset value
