[0039] The multi-carrier communication method, apparatus, and communication device provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0040] Please refer to Figure 2 , Figure 2This is a flowchart of a multi-carrier communication control method provided by an embodiment of the present application, and the multi-carrier communication control method is applied to a network side device. Figure 2 As shown, the multi-carrier communication control method includes the following steps:

[0041] Step 201: When the terminal is in multi-carrier aggregation or supplementary uplink, the network side device obtains the ability of the terminal to support a maximum uplink transmission time duty cycle on each activated carrier frequency band, and the ability of the terminal to support a maximum uplink transmission time duty cycle under the carrier frequency band combination corresponding to the multi-carrier frequency band.

[0042] It should be noted that when the terminal is in multi-carrier aggregation, it means that the terminal can transmit on at least two carrier frequency bands at the same time; the activated carrier frequency band refers to the carrier frequency band on which the terminal can perform resource scheduling. Among them, the power level and the maximum uplink transmission time duty cycle supported by the terminal on each activated carrier frequency band are different. The terminal can report the maximum uplink transmission time duty cycle supported by the terminal under the carrier frequency band combination corresponding to the multi-carrier frequency band based on the power level on each activated carrier frequency band, and the ability to report the maximum uplink transmission time duty cycle supported by the terminal on each activated carrier frequency band. In this way, the network-side device can also obtain the above parameters reported by the terminal.

[0043] Step 202: The network-side device adjusts the actual uplink transmission time of the terminal on each of the activated carrier frequency bands to obtain the actual uplink transmission time duty cycle of the terminal on each of the activated carrier frequency bands, so that the actual uplink transmission time duty cycle of the terminal on each of the activated carrier frequency bands, the maximum uplink transmission time duty cycle capability supported by the terminal on each of the activated carrier frequency bands, and the maximum uplink transmission time duty cycle capability supported by the terminal under the carrier frequency band combination corresponding to the multi-carrier frequency bands meet a preset relationship.

[0044] It should be noted that after determining the transmission power corresponding to the activated carrier frequency band of the terminal, the terminal's ability to support the maximum uplink transmission time duty cycle on each activated carrier frequency band and the terminal's ability to support the maximum uplink transmission time duty cycle under the carrier frequency band combination corresponding to the multi-carrier frequency band, these two parameters can be considered to be certain values; and the actual uplink transmission time duty cycle of the terminal on each activated carrier frequency band is determined according to the terminal's signal transmission situation, which is not a fixed value.

[0045] In an embodiment of the present application, the network-side device adjusts the actual uplink transmission time of the terminal on each activated carrier frequency band, thereby obtaining the actual uplink transmission time duty cycle of the terminal on each activated carrier frequency band, so that the actual uplink transmission time duty cycle of the terminal on each activated carrier frequency band, the maximum uplink transmission time duty cycle capability supported by the terminal on each activated carrier frequency band, and the maximum uplink transmission time duty cycle capability supported by the terminal in the carrier frequency band combination corresponding to the multi-carrier frequency band meet a preset relationship, thereby ensuring that the terminal meets the overall radiation within the standard. The overall radiation of the terminal can be characterized by the specific absorption ratio (SAR) and the maximum permissible exposure (MPE). For example, when the above-mentioned preset relationship is met, 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, the overall radiation emitted simultaneously by the terminal on multiple activated carrier frequency bands will not exceed the standard, thereby avoiding damage to the user due to excessive radiation, thereby improving the user experience of the terminal.

[0046] Optionally, the terminal in the embodiment of the present application is a terminal having a transmit power greater than a preset power. The preset power may be 23dBm. In mobile communications, terminal power is defined as multiple power classes: 23dBm, 26dBm, 29dBm, 31dBm, and so on. In some implementation scenarios, a terminal having a transmit power greater than 23dBm may also be referred to as a high-power terminal.

[0047] In some embodiments, when the maximum transmit power supported by the target activated carrier frequency band is greater than the preset power, the terminal's capability of a maximum uplink transmission time duty cycle supported by the target activated carrier frequency band is a first preset value;

[0048] When the maximum transmit power supported by the target activated carrier frequency band is less than or equal to the preset power, the capability of the terminal to support a maximum uplink transmission time duty cycle in the target activated carrier frequency band is a second preset value;

[0049] The target activated carrier frequency band is any one of the activated carrier frequency bands corresponding to the multi-carrier aggregation.

[0050] Optionally, the preset power may be 23dBm. When the maximum transmit power of the activated carrier frequency band is greater than 23dBm, the maximum uplink transmission time duty cycle capability supported by the activated carrier frequency band is a first preset value. When the maximum transmit power of the activated carrier frequency band is less than or equal to 23dBm, the maximum uplink transmission time duty cycle capability supported by the activated carrier frequency band is a second preset value. The first preset value may be 0.5, and the second preset value may be 1. Of course, the first preset value may also be other values, and the second preset value may also be other values, which are not specifically limited in the embodiments of the present application.

[0051] For example, if the maximum transmit power of the activated carrier frequency band is 26 dBm, the maximum uplink transmission time duty cycle capability supported by the activated carrier frequency band may be 0.5.

[0052] Optionally, in an embodiment of the present application, when the terminal does not report the capability of the maximum uplink transmission time duty cycle supported by the terminal under the carrier frequency band combination corresponding to the multi-carrier frequency band, the capability of the maximum uplink transmission time duty cycle supported by the terminal under the carrier frequency band combination corresponding to the multi-carrier frequency band is a first default value;

[0053] 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 capability of the maximum uplink transmission time duty cycle supported by the terminal under the carrier frequency band combination corresponding to the multi-carrier frequency band, and the capability of the maximum uplink transmission time duty cycle supported by the terminal under the carrier frequency band combination corresponding to the multi-carrier frequency band is the second default value.

[0054] Among them, when the maximum transmission power supported by the activated carrier frequency band is greater than the preset power, the terminal will report the ability of the maximum uplink transmission time duty cycle supported under the carrier frequency band combination corresponding to the multi-carrier frequency band, and the value range of this parameter is 0~1. Among them, the preset power can be 23dBm. For example, the maximum transmission power supported by the terminal on the activated carrier frequency band is 26dBm. If the terminal does not report the ability of the maximum uplink transmission time duty cycle supported under the carrier frequency band combination corresponding to the multi-carrier frequency band, the ability of the maximum uplink transmission time duty cycle supported by the terminal under the carrier frequency band combination corresponding to the multi-carrier frequency band is defaulted to the first default value, for example, the first default value is 0.5. Of course, the first default value can also be other values ​​in the range of 0~1, and the embodiments of the present application do not make specific restrictions on this.

[0055] When the maximum transmission power supported by the activated carrier frequency band is less than or equal to the preset power, for example, the maximum transmission power supported by the terminal on the activated carrier frequency band is 23dBm, the terminal does not need to report its ability to support the maximum uplink transmission time duty cycle under the carrier frequency band combination corresponding to the multi-carrier frequency band, and the default value of this parameter is the second default value, for example, the second default value is 1, and the second default value can also be other values, which is not specifically limited in the embodiments of the present application.

[0056] It should be noted that the actual uplink transmission time duty cycle of the terminal on each of the activated carrier frequency bands, the maximum uplink transmission time duty cycle capability supported by the terminal on each of the activated carrier frequency bands, and the maximum uplink transmission time duty cycle capability supported by the terminal under the carrier frequency band combination corresponding to the multi-carrier frequency bands satisfy a preset relationship. It can be that the ratio between the actual uplink transmission time duty cycle of the terminal on each of the activated carrier frequency bands and the maximum uplink transmission time duty cycle capability supported by the terminal on each of the activated carrier frequency bands is less than the maximum uplink transmission time duty cycle capability supported by the terminal under the carrier frequency band combination corresponding to the multi-carrier frequency bands.

[0057] In the embodiment of the present application, the preset relationship is:

[0058]

[0059] Wherein, n is the number of activated carrier frequency bands, xn is the nth activated carrier frequency band, duty xn dutycycle is the actual uplink transmission time duty cycle of the terminal on the nth activated carrier frequency band. xn CA_dutycycle is the maximum uplink transmission time duty cycle capability supported by the terminal on the nth activated carrier frequency band, and CA_dutycycle is the maximum uplink transmission time duty cycle capability supported by the terminal in the carrier frequency band combination corresponding to the multi-carrier frequency band.

[0060] For better understanding, the solutions provided in the embodiments of the present application will be described below through several specific implementation methods.

[0061] Implementation Method 1

[0062] When the terminal is in the case of two carrier aggregation, that is, the terminal can transmit on two activated carrier frequency bands at the same time, that is, the number of activated carrier frequency bands of the terminal is 2 (n=2); in this case, the above preset relationship can be expressed by the following formula:

[0063]

[0064] Among them, duty x1dutycycle is the actual uplink transmission duty cycle of the terminal on the first activated carrier frequency band x1. x1 The maximum uplink transmission time duty cycle capability supported by the terminal on the first activated carrier frequency band x1, duty x2 dutycycle is the actual uplink transmission duty cycle of the terminal on the second activated carrier frequency band x2. x2 CA_dutycycle is the maximum uplink transmission time duty cycle capability supported by the terminal on the second activated carrier frequency band x2, and CA_dutycycle is the maximum uplink transmission time duty cycle capability supported by the terminal under the carrier frequency band combination corresponding to the two carrier frequency bands.

[0065] In this embodiment, the network side device can adjust the actual uplink transmission time of the terminal on the activated carrier frequency band x1 and the activated carrier frequency band x2 respectively, thereby obtaining the actual uplink transmission time duty ratio duty of the terminal on the two activated carrier frequency bands. x1 and duty x2 , so that the actual uplink transmission time duty cycle of the terminal on the two carrier frequency bands calculated using the above formula is less than or equal to CA_dutycycle, thereby ensuring that the overall radiation emitted by the terminal on the two activated carrier frequency bands simultaneously does not exceed the standard.

[0066] Implementation Method 2

[0067] When the terminal is in the Supplementary Uplink (SUL), the maximum transmit power supported by the terminal on the SUL by default is 23dBm, and the maximum uplink transmission time duty cycle supported by the terminal on the link is dutycycle. sul is 1;

[0068] The terminal can transmit on the New Radio (NR) carrier band at the same time, that is, the terminal can transmit on two activated carrier bands (NR and SUL carrier bands) at the same time, and the number of activated carrier bands of the terminal is 2 (n=2); in this case, the above preset relationship can be expressed by the following formula:

[0069]

[0070] Among them, duty x1 dutycycle is the actual uplink transmission time duty cycle of the terminal on the NR carrier frequency band. x1 The maximum uplink transmission time duty cycle capability supported by the terminal on the NR carrier frequency band, duty sul dutycycle is the actual uplink transmission duty cycle of the terminal on the supplementary uplink SUL.sul It is the capability of the terminal to support a maximum uplink transmission time duty cycle on the supplementary uplink SUL, and CA_dutycycle is the capability of the terminal to support a maximum uplink transmission time duty cycle under the carrier frequency band combination corresponding to the NR and SUL carrier frequency bands.

[0071] In this embodiment, the network side device can adjust the actual uplink transmission time of the terminal on the carrier frequency band NR and SUL respectively, thereby obtaining the actual uplink transmission time duty ratio duty of the terminal on these two carrier frequency bands. x1 and duty sul , so that the actual uplink transmission time duty cycle of the terminal on the two carrier frequency bands is less than or equal to CA_dutycycle after calculation using the above formula, thereby ensuring that the overall radiation emitted by the terminal on the two carrier frequency bands simultaneously does not exceed the standard.

[0072] Implementation Method 3

[0073] When the terminal is in three carrier aggregation, the terminal can transmit on three activated carrier frequency bands at the same time, that is, the number of activated carrier frequency bands of the terminal is 3 (n=3); in this case, the above preset relationship can be expressed by the following formula:

[0074]

[0075] Among them, duty x1 dutycycle is the actual uplink transmission duty cycle of the terminal on the first activated carrier frequency band x1. x1 The maximum uplink transmission time duty cycle capability supported by the terminal on the first activated carrier frequency band x1, duty x2 dutycycle is the actual uplink transmission duty cycle of the terminal on the second activated carrier frequency band x2. x2 The maximum uplink transmission time duty cycle capability supported by the terminal on the second activated carrier frequency band x2, duty x3 dutycycle is the actual uplink transmission duty cycle of the terminal on the third activated carrier frequency band x3. x3 CA_dutycycle is the maximum uplink transmission time duty cycle capability supported by the terminal on the third activated carrier frequency band x3, and CA_dutycycle is the maximum uplink transmission time duty cycle capability supported by the terminal under the carrier frequency band combination corresponding to these three carrier frequency bands.

[0076] In this embodiment, the network side device can adjust the actual uplink transmission time of the terminal on the three activated carrier frequency bands x1, x2 and x3 respectively, and then obtain the actual uplink transmission time duty cycle duty of the terminal on each of the activated carrier frequency bands. x1 、duty x2 and duty x3 , so that the actual uplink transmission time duty cycle of the terminal on the three carrier frequency bands is less than or equal to CA_dutycycle after calculation using the above formula, thereby ensuring that the overall radiation emitted by the terminal on the three activated carrier frequency bands simultaneously does not exceed the standard.

[0077] Implementation Method 4

[0078] When a terminal is in n carrier aggregation, it can transmit on n activated carrier frequency bands at the same time, that is, the number of activated carrier frequency bands of the terminal is n (n≥2). In this case, the above preset relationship can be expressed by the following formula:

[0079]

[0080] Wherein, n is the number of activated carrier frequency bands, duty x1 dutycycle is the actual uplink transmission duty cycle of the terminal on the first activated carrier frequency band x1. x1 The maximum uplink transmission time duty cycle capability supported by the terminal on the first activated carrier frequency band x1, duty x2 dutycycle is the actual uplink transmission duty cycle of the terminal on the second activated carrier frequency band x2. x2 The maximum uplink transmission time duty cycle capability supported by the terminal on the second activated carrier frequency band x2, duty xn dutycycle is the actual uplink transmission duty cycle of the terminal on the nth activated carrier frequency band xn, xn CA_dutycycle is the maximum uplink transmission time duty cycle capability supported by the terminal on the nth activated carrier frequency band xn, and CA_dutycycle is the maximum uplink transmission time duty cycle capability supported by the terminal under the carrier frequency band combination corresponding to these n carrier frequency bands.

[0081] It should be noted that for a single activated carrier frequency band, such as x1, if the maximum transmit power supported by the terminal on the activated carrier frequency band x1 is 26dBm, and the maximum uplink duty cycle supported by the terminal is maxUplinkDutyCycle-PC2-FR1, then the maximum uplink transmission time duty cycle capability supported on the activated carrier frequency band is dutycycle x1=maxUplinkDutyCycle-PC2-FR1.

[0082] For a single activated carrier frequency band, for example, x2, if the maximum transmit power supported by the terminal on the activated carrier frequency band x2 is 29dBm, the maximum uplink duty cycle supported by the terminal is reported as maxUplinkDutyCycle-PC2-FR1, and the maximum uplink duty cycle actually supported by the terminal is maxUplinkDutyCycle-PC2-FR1×0.5, then the maximum uplink transmission time duty cycle capability supported on the activated carrier frequency band is dutycycle x2 =maxUplinkDutyCycle-PC2-FR1×0.5.

[0083] In this embodiment, the network side device can adjust the actual uplink transmission time of the terminal on n activated carrier frequency bands respectively, and then obtain the actual uplink transmission time duty cycle duty of the terminal on each of the activated carrier frequency bands. x1 、duty x2 …duty xn , so that the actual uplink transmission time duty cycle of the terminal on the n carrier frequency bands calculated using the above formula is less than or equal to CA_dutycycle, thereby ensuring that the overall radiation emitted by the terminal on these n activated carrier frequency bands simultaneously does not exceed the standard.

[0084] Please refer to Figure 3 , Figure 3 This is a flowchart of another multi-carrier communication control method provided by an embodiment of the present application, wherein the multi-carrier communication control method is applied to a terminal. Figure 3 As shown, the multi-carrier communication control method includes the following steps:
