[0022] Hereinafter, with reference to the drawings, some embodiments and their application scenarios will be used to describe in detail the multi-carrier communication method, apparatus, and communication device according to the embodiments of the present application.

[0023] FIG. 2 is a flowchart of a multi-carrier communication control method according to an embodiment of the present application, and the multi-carrier communication control method is used in a network-side device. As shown in FIG. 2, the multi-carrier communication control method includes the following steps.

[0024] Step 201, when the terminal is in multi-carrier aggregation or an auxiliary uplink, the network-side device obtains the ability of the terminal to support the maximum uplink transmission time duty ratio on each activated carrier frequency band and the ability of the terminal to support the maximum uplink transmission time duty ratio in a combination of carrier frequency bands corresponding to the multi-carrier frequency band.

[0025] It should be noted that when a terminal is in multi - carrier aggregation, it means that the terminal can simultaneously transmit on at least two carrier frequency bands. The activated carrier frequency band is the carrier frequency band on which the terminal can perform resource scheduling. Here, the power class and the maximum uplink transmission time duty ratio supported on each activated carrier frequency band of the terminal are different. The terminal reports the ability of the maximum uplink transmission time duty ratio supported by the combination of carrier frequency bands corresponding to the multi - carrier frequency band based on the power class on each activated carrier frequency band, and can report the ability of the maximum uplink transmission time duty ratio supported on each activated carrier frequency band. In this way, the network - side device can obtain the above - mentioned parameters reported by the terminal.

[0026] Step 202: The network - side device adjusts the actual uplink transmission time on each activated carrier frequency band of the terminal so that the actual uplink transmission time duty ratio on each activated carrier frequency band of the terminal, the ability of the maximum uplink transmission time duty ratio supported on each activated carrier frequency band of the terminal, and the ability of the maximum uplink transmission time duty ratio supported by the combination of carrier frequency bands corresponding to the multi - carrier frequency band of the terminal satisfy a preset relationship, and obtains the actual uplink transmission time duty ratio on each activated carrier frequency band of the terminal.

[0027] It should be noted that after determining the transmission power corresponding to the active carrier frequency band of the terminal, the two parameters, namely, the maximum uplink transmission time duty ratio supported by the terminal on each active carrier frequency band and the maximum uplink transmission time duty ratio supported by the terminal in the combination of carrier frequency bands corresponding to the multi-carrier frequency band, may be considered as constant values. However, the actual uplink transmission time duty ratio on each active carrier frequency band of the terminal is determined according to the signal transmission situation of the terminal and is not a constant value.

[0028] In the embodiment of the present application, the network-side device adjusts the actual uplink transmission time on each active carrier frequency band of the terminal, thereby obtaining the actual uplink transmission time duty ratio on each active carrier frequency band of the terminal, and making the actual uplink transmission time duty ratio on each active carrier frequency band of the terminal satisfy the preset relationship with the maximum uplink transmission time duty ratio supported by the terminal on each active carrier frequency band and the maximum uplink transmission time duty ratio supported by the terminal in the combination of carrier frequency bands corresponding to the multi-carrier frequency band, so as to ensure that the overall radiation of the terminal does not exceed the standard. Here, the overall radiation of the terminal may be characterized by the Specific Absorption Ratio (SAR) and the Maximum Permissible Exposure (MPE). For example, when the preset relationship is satisfied, the SAR of the terminal does not exceed the preset SAR threshold, or the MPE of the terminal does not exceed the preset MPE threshold. In this way, when the terminal is in multi-carrier aggregation, it can be ensured that the overall radiation emitted by the terminal simultaneously on multiple active carrier frequency bands does not exceed the standard, thereby avoiding damage to the user caused by the radiation exceeding the standard and further improving the user experience of the terminal.

[0029] Optionally, the terminal in the embodiments of the present application is a terminal with a transmission power greater than a preset power. Here, the preset power may be 23 dBm. In mobile communication, the power of a terminal is defined as multiple power classes such as 23 dBm, 26 dBm, 29 dBm, 31 dBm, etc. In some implementation scenarios, a terminal with a transmission power greater than 23 dBm may be called a high-output terminal.

[0030] In some embodiments, when the maximum transmission power supported by the target activation carrier frequency band is greater than a preset power, the ability of the terminal to support the maximum uplink transmission time duty ratio in the target activation carrier frequency band is a first preset value. When the maximum transmission power supported by the target activation carrier frequency band is less than or equal to the preset power, the ability of the terminal to support the maximum uplink transmission time duty ratio in the target activation carrier frequency band is a second preset value. Here, the target activation carrier frequency band is any one of the activation carrier frequency bands corresponding to the multi-carrier aggregation.

[0031] Optionally, the preset power may be 23 dBm. When the maximum transmission power of the activated carrier frequency band is greater than 23 dBm, the maximum uplink transmission time duty ratio capability supported by this activated carrier frequency band is the first preset value. When the maximum transmission power of the activated carrier frequency band is 23 dBm or less, the maximum uplink transmission time duty ratio capability supported by this activated carrier frequency band is the second preset value. Here, the first preset value may be 0.5, and the second preset value may be 1. Of course, the first preset value may be other numerical values, and the second preset value may be other numerical values. The embodiments of the present application do not specifically limit this.

[0032] For example, if the maximum transmission power of the activated carrier frequency band is 26 dBm, the maximum uplink transmission time duty ratio capability supported by this activated carrier frequency band may be 0.5.

[0033] Optionally, in the embodiments of the present application, when the terminal does not report the maximum uplink transmission time duty ratio capability supported by the combination of carrier frequency bands corresponding to the multi-carrier frequency band of the terminal, the maximum uplink transmission time duty ratio capability supported by the combination of carrier frequency bands corresponding to the multi-carrier frequency band of the terminal is the first default value. When the maximum transmission power supported by the activated carrier frequency band is less than or equal to the preset power, the terminal does not report the maximum uplink transmission time duty ratio capability supported by the combination of carrier frequency bands corresponding to the multi-carrier frequency band of the terminal, and the maximum uplink transmission time duty ratio capability supported by the combination of carrier frequency bands corresponding to the multi-carrier frequency band of the terminal is the second default value.

[0034] Here, when the maximum transmission power supported by the activated carrier frequency band is greater than the preset power, the terminal reports the maximum uplink transmission time duty ratio support capability in the combination of carrier frequency bands corresponding to the multi-carrier frequency band. The value range of this parameter is from 0 to 1. Here, the preset power may be 23 dBm. For example, if the maximum transmission power supported by the terminal on the activated carrier frequency band is 26 dBm and the terminal does not report the maximum uplink transmission time duty ratio support capability in the combination of carrier frequency bands corresponding to the multi-carrier frequency band, by default, the maximum uplink transmission time duty ratio support capability of the terminal in the combination of carrier frequency bands corresponding to the multi-carrier frequency band is the first default value. For example, the first default value is 0.5. Of course, the first default value may be other numerical values within the range of 0 to 1, and the embodiments of this application do not specifically limit this.

[0035] When the maximum transmission power supported by the activated carrier frequency band is less than or equal to the preset power, for example, when the maximum transmission power supported by the terminal on the activated carrier frequency band is 23 dBm, the terminal does not need to report the maximum uplink transmission time duty ratio support capability in the combination of carrier frequency bands corresponding to the multi-carrier frequency band, and by default, the value of this parameter is the second default value. For example, the second default value is 1, and the second default value may be other numerical values, and the embodiments of this application do not specifically limit this.

[0036] It should be noted that the actual uplink transmission time duty ratio on each of the activated carrier frequency bands of the terminal, the ability of the terminal to support the maximum uplink transmission time duty ratio on each activated carrier frequency band, and the ability of the terminal to support the maximum uplink transmission time duty ratio in the combination of carrier frequency bands corresponding to the multi-carrier frequency band satisfy a preset relationship. This may mean that the ratio between the actual uplink transmission time duty ratio on each of the activated carrier frequency bands of the terminal and the ability of the terminal to support the maximum uplink transmission time duty ratio on each activated carrier frequency band is smaller than the ability of the terminal to support the maximum uplink transmission time duty ratio in the combination of carrier frequency bands corresponding to the multi-carrier frequency band, even if this is the case.

[0037] In the embodiments of the present application, the preset relationship is TIFF0007693093000001.tif12110, and here, n is the number of activated carrier frequency bands, xn is the nth activated carrier frequency band, and duty xn is the actual uplink transmission time duty ratio on the nth activated carrier frequency band of the terminal, and dutycycle xn is the ability of the terminal to support the maximum uplink transmission time duty ratio on the nth activated carrier frequency band, and CA_dutycycle is the ability of the terminal to support the maximum uplink transmission time duty ratio in the combination of carrier frequency bands corresponding to the multi-carrier frequency band.

[0038] For better understanding, the following will describe the solution according to the embodiments of the present application by means of several specific embodiments.

[0039] Embodiment 1 When the terminal is in two - carrier aggregation, that is, the terminal can transmit simultaneously on two activated carrier frequency bands, and the number of activated carrier frequency bands of the terminal is 2 (n = 2). In such a case, the above - preset relationship may be represented by the following formula: TIFF0007693093000002.tif1281Here, duty x1 is the actual uplink transmission time duty ratio on the first activated carrier frequency band x1 of the terminal, and dutycycle x1 is the ability of the terminal to support the maximum uplink transmission time duty ratio on the first activated carrier frequency band x1, and duty x2 is the actual uplink transmission time duty ratio on the second activated carrier frequency band x2 of the terminal, and dutycycle x2 is the ability of the terminal to support the maximum uplink transmission time duty ratio on the second activated carrier frequency band x2. CA_dutycycle is the ability of the terminal to support the maximum uplink transmission time duty ratio for the combination of carrier frequency bands corresponding to these two carrier frequency bands.

[0040] In this embodiment, the network - side device adjusts the actual uplink transmission times on the activated carrier frequency band x1 and the activated carrier frequency band x2 of the terminal respectively. Further, the terminal obtains the actual uplink transmission time duty ratios duty x1 and duty x2 on the two activated carrier frequency bands of the terminal respectively. After calculating the actual uplink transmission time duty ratios on the two carrier frequency bands of the terminal using the above formula, make them less than or equal to CA_dutycycle, and further ensure that the overall radiation when the terminal transmits simultaneously on these two activated carrier frequency bands does not exceed the standard.

[0041] Embodiment 2 When the terminal is on the supplementary uplink (SUL), the maximum transmit power that the terminal supports by default on the SUL is 23 dBm, and the maximum uplink transmission time duty cycle capability dutycycle that the terminal supports on this link sul is 1. The terminal can transmit simultaneously on the new radio (NR) carrier frequency band, that is, the terminal can transmit simultaneously on two activated carrier frequency bands (NR and SUL carrier frequency bands), and the number of activated carrier frequency bands of the terminal is 2 (n = 2). In such a case, the above preset relationship may be expressed by the following formula: TIFF0007693093000003.tif1282 Here, duty x1 is the actual uplink transmission time duty cycle on the NR carrier frequency band of the terminal, and dutycycle x1 is the maximum uplink transmission time duty cycle capability that the terminal supports on the NR carrier frequency band, and duty sul is the actual uplink transmission time duty cycle on the supplementary uplink SUL of the terminal, and dutycycle sul is the maximum uplink transmission time duty cycle capability that the terminal supports on the supplementary uplink SUL, and CA_dutycycle is the maximum uplink transmission time duty cycle capability that the terminal supports in the combination of carrier frequency bands corresponding to the NR and SUL carrier frequency bands.

[0042] In this embodiment, the network-side device adjusts the actual uplink transmission time on the NR and SUL carrier frequency bands of the terminal respectively, and further adjusts the actual uplink transmission time duty cycles duty x1 and duty sulAfter obtaining the above respectively, the actual uplink transmission time duty ratio on two carrier frequency bands of the terminal is calculated using the above formula and then made not more than CA_dutycycle. Furthermore, it can be ensured that the overall radiation when the terminal simultaneously transmits on these two carrier frequency bands does not exceed the standard.

[0043] Embodiment 3 When the terminal is in three-carrier aggregation, the terminal can simultaneously transmit on three activated carrier frequency bands, that is, the number of activated carrier frequency bands of the terminal is 3 (n = 3). In such a case, the above preset relationship may be represented by the following formula: TIFF0007693093000004.tif12104 Here, duty x1 is the actual uplink transmission time duty ratio on the first activated carrier frequency band x1 of the terminal, and dutycycle x1 is the ability of the terminal to support the maximum uplink transmission time duty ratio on the first activated carrier frequency band x1, and duty x2 is the actual uplink transmission time duty ratio on the second activated carrier frequency band x2 of the terminal, and dutycycle x2 is the ability of the terminal to support the maximum uplink transmission time duty ratio on the second activated carrier frequency band x2, and duty x3 is the actual uplink transmission time duty ratio on the third activated carrier frequency band x3 of the terminal, and dutycycle x3 is the ability of the terminal to support the maximum uplink transmission time duty ratio on the third activated carrier frequency band x3, and CA_dutycycle is the ability of the terminal to support the maximum uplink transmission time duty ratio on the combination of carrier frequency bands corresponding to these three carrier frequency bands.

[0044] In this embodiment, the network-side device adjusts the actual uplink transmission times on the three activated carrier frequency bands x1, x2, and x3 of the terminal respectively, and further adjusts the duty ratio of the actual uplink transmission time duty on each of the activated carrier frequency bands of the terminal x1 and duty x2 and duty x3 and obtains them respectively. After calculating the duty ratio of the actual uplink transmission time on the three carrier frequency bands of the terminal using the above formula, it is made less than or equal to CA_dutycycle. Furthermore, it can be ensured that the overall radiation when the terminal simultaneously transmits on these three activated carrier frequency bands does not exceed the standard.

[0045] Embodiment 4 When the terminal is in n-carrier aggregation, the terminal can simultaneously transmit on n activated carrier frequency bands, and the number of activated carrier frequency bands of the terminal is n (n≥2). In such a case, the preset relationship may be expressed by the following formula TIFF0007693093000005.tif12110Here, n is the number of the activated carrier frequency bands, and duty x1 is the duty ratio of the actual uplink transmission time on the first activated carrier frequency band x1 of the terminal, and dutycycle x1 is the maximum uplink transmission time duty ratio supportable by the terminal on the first activated carrier frequency band x1, and duty x2 is the duty ratio of the actual uplink transmission time on the second activated carrier frequency band x2 of the terminal, and dutycycle x2 is the maximum uplink transmission time duty ratio supportable by the terminal on the second activated carrier frequency band x2, and duty xn is the duty ratio of the actual uplink transmission time on the nth activated carrier frequency band xn of the terminal, and dutycycle xnis the maximum uplink transmission time duty cycle supportable by the terminal on the nth activated carrier frequency band xn, and CA_dutycycle is the maximum uplink transmission time duty cycle supportable by the terminal in the combination of carrier frequency bands corresponding to these n carrier frequency bands.

[0046] It should be noted that for a single activated carrier frequency band among them, such as x1, when the terminal reports that the maximum transmit power supported on this activated carrier frequency band x1 is 26 dBm and the maximum uplink duty cycle supported by the terminal is maxUplinkDutyCycle-PC2-FR1, the maximum uplink transmission time duty cycle supportable on this activated carrier frequency band is dutycycle x1 = maxUplinkDutyCycle-PC2-FR1.

[0047] For a single activated carrier frequency band among them, such as x2, the terminal reports that the maximum transmit power supported on this activated carrier frequency band x2 is 29 dBm and the maximum uplink duty cycle supported by the terminal is maxUplinkDutyCycle-PC2-FR1. When the maximum uplink duty cycle actually supported by the terminal is maxUplinkDutyCycle-PC2-FR1×0.5, the maximum uplink transmission time duty cycle supportable on this activated carrier frequency band is dutycycle x2 = maxUplinkDutyCycle-PC2-FR1×0.5.

[0048] In this embodiment, the network-side device adjusts the actual uplink transmission time of the terminal on each of the n activated carrier frequency bands, and further adjusts the actual uplink transmission time duty cycle duty x1 duty x2 ···dutyxn After obtaining them respectively and calculating the actual uplink transmission time duty ratio on the n carrier frequency bands of the terminal using the above formula, it is made to be equal to or less than CA_dutycycle. Furthermore, it is possible to ensure that the overall radiation simultaneously emitted by the terminal on these n activated carrier frequency bands does not exceed the standard.

[0049] Figure 3 is a flowchart of another multi-carrier communication control method according to an embodiment of the present application, and the multi-carrier communication control method is used in a terminal. As shown in Figure 3, the multi-carrier communication control method includes the following steps.

[0050] Step 301, when the terminal is in multi-carrier aggregation or an auxiliary uplink, the terminal reports to the network-side device the ability of the maximum uplink transmission time duty ratio supported by the terminal on each activated carrier frequency band and the ability of the maximum uplink transmission time duty ratio supported by the terminal in the combination of carrier frequency bands corresponding to the multi-carrier frequency band.

[0051] Here, the actual uplink transmission time duty ratio on each of the activated carrier frequency bands of the terminal, the ability of the maximum uplink transmission time duty ratio supported by the terminal on each activated carrier frequency band, and the ability of the maximum uplink transmission time duty ratio supported by the terminal in the combination of carrier frequency bands corresponding to the multi-carrier frequency band satisfy a preset relationship.

[0052] In an embodiment of the present application, when the terminal is in multi-carrier aggregation, the terminal reports to the network-side device the maximum uplink transmission time duty ratio capability supported by the terminal on each activated carrier frequency band and the maximum uplink transmission time duty ratio capability supported by the terminal in a combination of carrier frequency bands corresponding to the multi-carrier frequency band.
