[0156] FIG2A is an interactive diagram illustrating a method for determining transmit power according to an exemplary embodiment. As shown in FIG2A , the embodiment of the present disclosure relates to a method for determining transmit power, which is used in a communication system 100 and includes:

[0157] Step S2101: The terminal sends second information to the network device.

[0158] In some embodiments, the network device receives second information sent by the terminal.

[0159] In some embodiments, the terminal may be any type of communication device. The terminal may be a mobile terminal or a fixed terminal. For example, the terminal may be a mobile phone, a tablet computer, a smart office device, a smart home device, a vehicle-mounted device, and / or an aircraft device.

[0160] In some embodiments, the terminal may be a terminal supporting dual connectivity, multiple connectivity or carrier aggregation.

[0161] In some embodiments, the network device may include, but is not limited to, an access network device.

[0162] In some embodiments, the second information is used to indicate to the network device the power level of the uplink transmission of the terminal in different scenarios.

[0163] In some embodiments, the power class may be used to indicate the maximum transmit power supported by the terminal.

[0164] It should be noted that the transmit power of a terminal may generally be defined based on a power class (PC), that is, the maximum transmit power of the terminal cannot exceed a transmit power upper limit corresponding to the power class of the terminal.

[0165] In some embodiments, the second information includes at least one of the following:

[0166] The first information element (IE) is used to indicate the maximum transmit power of each frequency band of the terminal;

[0167] The second IE is used to indicate the maximum transmit power of the terminal's frequency band combination;

[0168] The third IE is used to indicate the maximum transmit power of each frequency band in the frequency band combination.

[0169] In some embodiments, the first IE may be used to carry the power level of each frequency band in multiple frequency bands supported by the terminal; that is, the terminal may report the power level of each frequency band (per band) supported by the terminal to the network device through the first IE.

[0170] It is worth noting that the power level carried by the first IE may be a power level at the frequency band level; the power level carried by the first IE is used to indicate the maximum transmit power supported by the terminal on each frequency band.

[0171] In some embodiments, the first IE may be ue-PowerClass.

[0172] In some embodiments, the second IE can be used to carry the power level of each frequency band combination in multiple frequency band combinations supported by the terminal; that is, the terminal can report the power level of each frequency band combination (per band combination) supported by the terminal to the network device through the second IE.

[0173] It is worth noting that the power level carried by the second IE can be the power level of the frequency band combination level; the power level of the frequency band combination level indicates the maximum transmit power on the frequency band combination. In other words, the sum of the transmit power of the terminal in each frequency band of the frequency band combination should be less than or equal to the maximum transmit power of the frequency band combination indicated by the power level corresponding to the frequency band combination.

[0174] In some embodiments, the second IE may be powerClass.

[0175] In some embodiments, the third IE can be used to carry the power level of each frequency band in each frequency band combination of multiple frequency band combinations supported by the terminal; that is, the terminal can report the power level of each frequency band (per band per band Combination) in each frequency band combination supported by the terminal to the network device through the third IE.

[0176] In some embodiments, the third IE may be ue-powerClassPerBandPerBC.

[0177] In some embodiments, the band combination may be a band combination of a carrier aggregation configuration.

[0178] Step S2102: The terminal sends first information to the network device.

[0179] In some embodiments, the network device receives first information sent by the terminal.

[0180] In some embodiments, the first information and the second information may be carried in the same message.

[0181] It is worth noting that the terminal may carry the first information and the second information in the same message, thereby sending the first information and the second information to the network device at the same time by sending the message to the network device.

[0182] In some embodiments, the first information and the second information may be carried in different messages.

[0183] In some embodiments, the first information is used by the network device to determine whether the terminal supports single-band transmission power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0184] In some embodiments, the terminal determines whether to send the first information to the network device based on its own capabilities.

[0185] It is worth noting that when a terminal is configured with carrier aggregation and determines to use a frequency band combination for carrier aggregation, if only one frequency band within the frequency band combination is in an operating state, the terminal may determine whether it needs to send first information to a network device based on the power capability of supporting or not supporting single-band transmit power within the frequency band when the frequency band combination is in an operating state. In this way, the first information can be used to inform the network device of the power capability of the terminal supporting or not supporting single-band transmit power within the frequency band when the frequency band combination is in an operating state, so that the network device can fully consider the power capability of the terminal when scheduling the terminal's transmit power, thereby achieving maximized uplink coverage.

[0186] In some embodiments, the first information is used to indicate that the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0187] It is worth noting that the terminal supports single-band transmission power in one frequency band when one frequency band of the frequency band combination is in working state. It can be understood that the maximum transmission power allowed by the terminal for single-band transmission in one frequency band of the frequency band combination configured by carrier aggregation depends on the single-band maximum transmission power corresponding to one frequency band.

[0188] Typically, if a terminal is configured with a band combination, regardless of whether the terminal is transmitting on a single band or multiple bands within the band combination, the network device considers the maximum transmit power of the band combination reported by the terminal when configuring transmit power for the terminal. This means that even if the terminal is transmitting on a single band within the band combination, its transmit power is limited by the band combination's maximum transmit power. This can result in over-constrained transmit power when the terminal is transmitting on a single band within the band combination.

[0189] In an embodiment of the present disclosure, if the terminal supports single-band transmission power in a frequency band when one frequency band of the frequency band combination is in an operating state, then when the terminal performs single-band transmission on a frequency band of the frequency band combination, the maximum transmission power of the terminal can depend only on the single-band maximum transmission power corresponding to one frequency band, and has nothing to do with the maximum transmission power of the frequency band combination; thereby, it is possible to select an appropriate power level according to the actual transmission situation of the terminal configured with the frequency band combination to avoid the problem of over-constraint of transmission power.

[0190] In some embodiments, the terminal sends first information to the network device, including:

[0191] When one frequency band of the frequency band combination is in an operating state, the terminal supports single-band transmission power in one frequency band and sends first information to the network device.

[0192] It can be understood that when the maximum transmission power allowed by the terminal for single-band transmission in a frequency band of the frequency band combination configured by carrier aggregation depends on the single-band maximum transmission power corresponding to a frequency band, the terminal sends the first information to the network device so that the network device configures the appropriate transmission power for the terminal according to the actual transmission situation of the terminal.

[0193] In some other embodiments, the method further comprises:

[0194] When one frequency band of the frequency band combination is in an operating state, the terminal does not support single-band transmission power in one frequency band and does not send the first information to the network device.

[0195] It is understandable that, when the maximum transmit power when the terminal is not allowed to perform single-band transmission in a frequency band of the frequency band combination configured for carrier aggregation depends on the single-band maximum transmit power corresponding to the frequency band, the terminal does not send the first information to the network device. That is, when the network device configures the transmit power for the terminal, the network device may determine the transmit power of the terminal based on the maximum transmit power of the frequency band combination reported by the terminal.

[0196] In some embodiments, a frequency band of the frequency band combination is in an operating state, including at least one of the following:

[0197] One band of the band combination is active;

[0198] There is uplink scheduling on one frequency band of the frequency band combination.

[0199] It is worth noting that, when one frequency band of the frequency band combination is in an activated state, it can be understood that only one frequency band among multiple frequency bands in the frequency band combination is in an activated state, and the other frequency bands are in a deactivated state.

[0200] Uplink scheduling on a frequency band in the frequency band combination can be understood as only one frequency band among multiple frequency bands in the frequency band combination is scheduled for uplink transmission.

[0201] It should be noted that only one of the multiple frequency bands in the frequency band combination is scheduled for uplink transmission. It can be that all the multiple frequency bands in the frequency band combination are in an activated state, but only one of the multiple frequency bands is scheduled for uplink transmission; or, it can be that only one of the multiple frequency bands in the frequency band combination is in an activated state, and the frequency band is scheduled for uplink transmission.

[0202] In some embodiments, the first information may be reported according to different frequency band combinations configured by the terminal.

[0203] In some embodiments, the reporting granularity of the first information may be per band combination.

[0204] Step S2103: The network device determines the configuration information of the uplink scheduling.

[0205] In some embodiments, the network device determines the configuration information of the uplink scheduling according to the power capability supported by the terminal when one frequency band of the frequency band combination is in an operating state.

[0206] In some embodiments, the power capability supported by the terminal when one frequency band of the frequency band combination is in an active state may indicate one of the following:

[0207] The terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in operation;

[0208] When a terminal is operating in one band of a band combination, it does not support single-band transmit power in one band.

[0209] It's worth noting that when configuring uplink scheduling, network equipment can fully consider the power capabilities of the terminal. If the terminal supports single-band transmit power in a frequency band combination when one band is active, the network equipment can configure transmit power based on the terminal's supported single-band transmit power; or, alternatively, configure uplink resources based on the terminal's supported single-band transmit power, thereby achieving maximum uplink coverage.

[0210] In some embodiments, the method further comprises:

[0211] The network device determines whether the terminal supports single-band transmit power in one frequency band when the terminal is in an operating state in one frequency band of the frequency band combination.

[0212] In some embodiments, the network device determines, based on whether the first information is received, whether the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0213] In some embodiments, the first information is used by the network device to determine whether the terminal supports single-band transmission power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0214] In some embodiments, the first information is used to indicate that the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0215] In the above embodiment, by limiting the first information to indicate that the terminal supports single-band transmission power in a frequency band when one frequency band of the frequency band combination is in a working state, the network device can obtain the power capability of the terminal that supports or does not support single-band transmission power in a frequency band when one frequency band of the frequency band combination is in a working state based on whether the first information is received, thereby effectively reducing signaling overhead.

[0216] In some embodiments, the network device determines whether the terminal supports single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state, including one of the following:

[0217] determining, based on whether the first information is received, whether the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state;

[0218] According to whether the first information and / or the third IE are received, it is determined whether the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0219] It is worth noting that there are two implementation methods for the network to determine whether the terminal supports single-band transmit power in one frequency band when the terminal is in an operating state in one frequency band of the frequency band combination.

[0220] In a first implementation manner, the network device may directly determine, based on whether the first information is received, whether the terminal supports or does not support single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state.

[0221] In a second implementation, the network device determines whether the terminal supports or does not support single-band transmission power in a frequency band when a frequency band of the frequency band combination is in an operating state based not only on whether the first information is received but also on whether the third IE is received.

[0222] In the first implementation, the transmit power of the terminal in a frequency band of the frequency band combination depends only on the single-band transmit power of a frequency band indicated by the first IE, and is not related to the maximum transmit power of the frequency band combination indicated by the second IE or the maximum transmit power of a frequency band of the frequency band combination indicated by the third IE.

[0223] In some embodiments, determining, based on whether the first information is received, whether the terminal supports single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state includes:

[0224] Upon receiving the first information, determining that the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state; or,

[0225] When the first information is not received, it is determined that the terminal does not support single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0226] It should be noted that the first information is used to indicate that the terminal supports single-band transmit power within a frequency band when one frequency band of the frequency band combination is in an operating state. If the network device receives the first information sent by the terminal, it may determine that the terminal supports single-band transmit power within a frequency band when one frequency band of the frequency band combination is in an operating state. If the network device does not receive the first information sent by the terminal, it may determine that the terminal does not support single-band transmit power within a frequency band when one frequency band of the frequency band combination is in an operating state.

[0227] It is worth noting that the method of determining whether the terminal supports single-band transmission power in a frequency band when a frequency band of the frequency band combination is in a working state is directly based on whether the network device receives the first information. The transmission power of the terminal in a frequency band of the frequency band combination depends only on the single-band transmission power of a frequency band indicated by the first IE, and has nothing to do with the maximum transmission power of the frequency band combination indicated by the second IE and the maximum transmission power of a frequency band of the frequency band combination indicated by the third IE.

[0228] It can be understood that in this case, regardless of whether the network device receives the third IE, as long as the network device receives the first information, the network device can determine that the terminal supports single-band transmission power in one frequency band when one frequency band of the frequency band combination is in working state.

[0229] In some embodiments, the method further comprises:

[0230] When receiving the first information, the network device determines the power configuration of the uplink scheduling according to the first IE.

[0231] In some embodiments, the network device determines the power configuration of the uplink scheduling according to the first IE, including: configuring the transmit power according to the single-band transmit power indicated by the first IE.

[0232] It should be noted that when the network device receives the first information sent by the terminal, it can determine the single-band transmission power supported in one frequency band when one frequency band of the frequency band combination is in a working state; in this case, the network device can determine the maximum transmission power supported by one frequency band of the terminal when one frequency band of the frequency band combination is in a working state based on the single-band transmission power indicated by the first IE, so as to configure the transmission power according to the single-band transmission power indicated by the first IE, thereby reducing the situation where the terminal is over-constrained in power when performing single-band transmission on a frequency band of the frequency band combination.

[0233] In some embodiments, the method further comprises:

[0234] When the first information is not received, the network device determines the power configuration of the uplink scheduling according to the first IE and the second IE.

[0235] It should be noted that when the network device does not receive the first information sent by the terminal, it can be determined that the single-band transmission power in a frequency band is not supported when one frequency band of the frequency band combination is in a working state; in this case, the maximum transmission power supported by one frequency band when the terminal is in a working state is not only limited by the single-band transmission power indicated by the first IE, but also limited by the maximum transmission power of the frequency band combination indicated by the second IE.

[0236] In some embodiments, when the first information is not received, the network device may configure the transmit power of the terminal according to the minimum value of the maximum transmit power of the frequency band combination indicated by the second IE and the single frequency band transmit power indicated by the first IE.

[0237] In a second implementation, the network device determines whether the terminal supports single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state, depending not only on whether the first information is received, but also on whether the third IE is received.

[0238] In some embodiments, determining, based on whether the first information and / or the third IE is received, whether the terminal supports single-band transmit power in a frequency band when one frequency band of the frequency band combination is in an operating state includes one of the following:

[0239] When the first information is not received, determining that the terminal does not support single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state;

[0240] When the first information is received, it is determined whether the terminal supports the single-band transmit power of one frequency band when one frequency band of the frequency band combination is in an operating state according to whether the third IE is received.

[0241] It should be noted that the first information is used to indicate that the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state. If the network device does not receive the first information sent by the terminal, it may determine that the terminal does not support single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state. If the network device receives the first information sent by the terminal, it is necessary to further determine whether the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state based on whether the third IE is received.

[0242] In some embodiments, when the first information is received, determining whether the terminal supports single-band transmit power of a frequency band when one frequency band of the frequency band combination is in an operating state based on whether the third IE is received includes one of the following:

[0243] When the first information is received and the third IE is not received, determining that the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state;

[0244] When the first information and the third IE are received, it is determined that the terminal does not support single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0245] Since the third IE indicates the maximum transmit power supported by the terminal on each frequency band in the frequency band combination, when a frequency band combination using carrier aggregation is determined and only one frequency band in the frequency band combination is in working state, the priority of the third IE is higher than the priority of the first IE.

[0246] If the network device receives the first information sent by the terminal and does not receive the third IE, it can be determined that the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0247] If the network device receives the first information sent by the terminal and receives the third IE, it can be determined that the terminal does not support single-band transmission power in one frequency band when one frequency band of the frequency band combination is in an operating state; in this case, the terminal supports the maximum transmission power on one frequency band of the frequency band combination when one frequency band of the frequency band combination is in an operating state.

[0248] In some embodiments, the method further comprises:

[0249] When the first information and the third IE are not received, the network device determines the power configuration of the uplink scheduling according to the first IE and the second IE;

[0250] When the first information is not received and the third IE is received, the network device determines the power configuration of the uplink scheduling according to the second IE and the third IE.

[0251] It is worth noting that if the network device does not receive the first information, it means that the terminal does not support single-band transmit power in one band when one band of the band combination is in an operating state. In this case, when the network device determines the uplink scheduled power of the terminal, it needs to further determine whether the third IE is received.

[0252] It can be understood that since the third IE indicates the maximum transmit power of each frequency band of the frequency band combination, when the first information and the third IE are not received, the maximum transmit power supported by the terminal in one frequency band of the frequency band combination when the frequency band is in an operating state is limited by the single-band transmit power indicated by the first IE and the maximum transmit power of the frequency band combination indicated by the second IE.

[0253] In this case, the network device can configure the transmit power of the terminal according to the minimum value of the maximum transmit power of the frequency band combination indicated by the second IE and the single frequency band transmit power indicated by the first IE.

[0254] When the first information is not received and the third IE is received, the maximum transmit power supported by the terminal in one frequency band of the frequency band combination when the frequency band is in an operating state is limited by the maximum transmit power of each frequency band in the frequency band combination indicated by the third IE and the maximum transmit power of the frequency band combination indicated by the second IE.

[0255] In this case, the network device can configure the transmit power of the terminal according to the minimum value of the maximum transmit power of the frequency band combination indicated by the second IE and the single frequency band transmit power indicated by the third IE.

[0256] In some embodiments, the method further comprises:

[0257] When the first information is received and the third IE is not received, the network device determines the power configuration for uplink scheduling according to the first IE;

[0258] When receiving the first information and the third IE, the network device determines the power configuration of the uplink scheduling according to the third IE.

[0259] It is worth noting that if the network device receives the first information but does not receive the third IE, it indicates that the terminal supports a single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state. In this case, the network device can determine the maximum transmit power supported by the terminal in one frequency band of the frequency band combination when the terminal is in an operating state based on the single-band transmit power indicated by the first IE, and configure the transmit power according to the single-band transmit power indicated by the first IE, thereby reducing the situation where the terminal is over-constrained in power when performing a single-band transmission on a frequency band of the frequency band combination.

[0260] If the network device receives the first information and receives the third IE, it means that the terminal does not support single-band transmission power in one frequency band when one frequency band of the frequency band combination is in working state; however, the terminal supports the maximum transmission power on one frequency band of the frequency band combination when one frequency band of the frequency band combination is in working state.

[0261] In this case, the network device can determine the maximum transmit power supported by a frequency band when the terminal is in a working state based on the maximum transmit power of each frequency band in the frequency band combination indicated by the third IE; and configure the transmit power according to the single-band transmit power indicated by the third IE to reduce the situation where the terminal is over-constrained in power when performing single-band transmission on a frequency band in the frequency band combination.

[0262] In some embodiments, the method further comprises one of the following:

[0263] The single-band transmit power supported by the terminal in a frequency band when one of the frequency band combinations is in an operating state, and when only one carrier is transmitting on a frequency band, the maximum transmit power supported by the terminal in a frequency band when one of the frequency band combinations is in an operating state is determined based on the single-band transmit power of the frequency band.

[0264] When a frequency band of the frequency band combination is in working state, the terminal supports single-band transmission power in a frequency band, and when multiple carriers are transmitted on a frequency band, the maximum transmission power supported by the terminal in a frequency band when a frequency band of the frequency band combination is in working state is determined according to the maximum transmission power of the carrier aggregation in the frequency band corresponding to the frequency band.

[0265] It is worth noting that carrier aggregation can include inter-band carrier aggregation and intra-band carrier aggregation, depending on the frequency band in which the carriers are aggregated. When a terminal is configured with intra-band carrier aggregation, multiple carriers are transmitted simultaneously on the corresponding frequency band.

[0266] When a frequency band of the frequency band combination is in an operating state and the terminal supports single-band transmission power in a frequency band, the terminal can select an appropriate transmission power according to the number of carriers actually transmitted on a frequency band.

[0267] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0268] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".

[0269] The transmit power determination method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2103. For example, step S2101 may be implemented as an independent embodiment, and step S2101 combined with step S2103 may be implemented as an independent embodiment, but is not limited thereto.

[0270] In some embodiments, step S2101 and step S2102 may be executed in an interchanged order or simultaneously.

[0271] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that when a frequency band of the frequency band combination is in an operating state, the terminal does not support single-band transmit power in the frequency band, and the terminal may not send the first information to the network device.

[0272] In some embodiments, step S2102 and step S2103 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that when the terminal does not have uplink transmission, the network device does not need to determine the configuration information of the uplink scheduling.

[0273] FIG2B is an interactive diagram illustrating a method for determining transmit power according to an exemplary embodiment. As shown in FIG2B , the embodiment of the present disclosure relates to a method for determining transmit power, which is used in a communication system 100 and includes:

[0274] Step S2201: The terminal sends second information to the network device.

[0275] In some embodiments, the optional implementation of step S2201 can refer to the optional implementation of step S2101 in Figure 2A and other related parts of the embodiment involved in Figure 2A, which will not be repeated here.

[0276] Step S2202: The terminal sends first information to the network device.

[0277] In some embodiments, the network device receives first information sent by the terminal.

[0278] In some embodiments, the first information and the second information may be carried in the same message.

[0279] It is worth noting that the terminal may carry the first information and the second information in the same message, thereby sending the first information and the second information to the network device at the same time by sending the message to the network device.

[0280] In some embodiments, the first information and the second information may be carried in different messages.

[0281] In some embodiments, the first information is used by the network device to determine whether the terminal supports single-band transmission power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0282] In some embodiments, the terminal sends first information to the network device, including:

[0283] First information is sent to the network device according to whether the terminal supports single-band transmission power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0284] It is worth noting that when a terminal is configured with carrier aggregation and determines to use a frequency band combination for carrier aggregation, if only one frequency band within the frequency band combination is in an operating state, the terminal may send first information to the network device based on the power capability of supporting or not supporting single-band transmit power within the frequency band when the frequency band of the frequency band combination is in an operating state. In this way, the different information content carried by the first information can be used to inform the network device of the power capability of the terminal supporting or not supporting single-band transmit power within the frequency band when the frequency band of the frequency band combination is in an operating state, so that the network device can fully consider the power capability of the terminal when scheduling the transmit power of the terminal, thereby achieving maximized uplink coverage.

[0285] In some embodiments, the first information is used to indicate whether the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0286] It can be understood that the terminal can send the first information to the network device to use the first information to inform the network device whether the terminal supports single-band transmission power in a frequency band when a frequency band of the frequency band combination is in a working state, so as to facilitate the network device to determine the maximum transmission power of the terminal for single-band transmission on a frequency band of the frequency band combination.

[0287] It should be noted that the first information may include one or more indicator bits, and different bit values ​​of the indicator bits indicate whether the terminal supports single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state. It is worth noting that each indicator bit corresponds to a frequency band combination configured for carrier aggregation.

[0288] In some embodiments, the first information having a first value is used to indicate that the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state;

[0289] The first information having the second value is used to indicate that the terminal does not support single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0290] Here, the first value and the second value can be different bit values ​​of the indicator bit; the specific values ​​of the first value and the second value can be set according to actual needs, and the embodiments of the present disclosure do not limit this. In some embodiments, the first value can be 1 and the second value can be 0.

[0291] In some embodiments, sending first information to a network device according to whether the terminal supports single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state includes:

[0292] The terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state, and sends first information having a first value to the network device;

[0293] When one frequency band of the frequency band combination is in an operating state, the terminal does not support single-band transmit power in the frequency band, and sends first information having a second value to the network device.

[0294] It should be noted that the terminal supports single-band transmission power in a frequency band when one frequency band of the frequency band combination is in working state. It can be understood that the maximum transmission power allowed by the terminal for single-band transmission in a frequency band of the frequency band combination configured by carrier aggregation depends on the single-band maximum transmission power corresponding to a frequency band.

[0295] Typically, if a terminal is configured with a band combination, regardless of whether the terminal is transmitting on a single band or multiple bands within the band combination, the network device considers the maximum transmit power of the band combination reported by the terminal when configuring transmit power for the terminal. This means that even if the terminal is transmitting on a single band within the band combination, its transmit power is limited by the band combination's maximum transmit power. This can result in over-constrained transmit power when the terminal is transmitting on a single band within the band combination.

[0296] Based on this, in an embodiment of the present disclosure, when the terminal supports single-band transmission power in a frequency band when a frequency band of the frequency band combination is in a working state, the terminal sends first information with a first value to the network device, so that the network device configures the transmission power for the terminal when performing single-band transmission on a frequency band of the frequency band combination based on the single-band maximum transmission power of each frequency band supported by the terminal.

[0297] When the maximum transmission power of a terminal that is not allowed to perform single-band transmission in a frequency band combination configured by carrier aggregation depends on the single-band maximum transmission power corresponding to a frequency band, the terminal may send first information with a second value to the network device so that the network device configures the transmission power for the terminal according to the maximum transmission power of the frequency band combination supported by the terminal.

[0298] In this way, the maximum transmission power of the terminal performing single-band transmission on a frequency band of the frequency band combination is related to the maximum transmission power of the single-band of the frequency band actually transmitted by the terminal, but is not related to the maximum transmission power of the frequency band combination; thereby, it is possible to select an appropriate power level according to the actual transmission situation of the terminal configured with the frequency band combination to avoid the problem of over-constraint of transmission power.

[0299] In some embodiments, a frequency band of the frequency band combination is in an operating state, including at least one of the following:

[0300] One band of the band combination is active;

[0301] There is uplink scheduling on one frequency band of the frequency band combination.

[0302] It is worth noting that, when one frequency band of the frequency band combination is in an activated state, it can be understood that only one frequency band among multiple frequency bands in the frequency band combination is in an activated state, and the other frequency bands are in a deactivated state.

[0303] Uplink scheduling on a frequency band in the frequency band combination can be understood as only one frequency band among multiple frequency bands in the frequency band combination is scheduled for uplink transmission.

[0304] It should be noted that only one of the multiple frequency bands in the frequency band combination is scheduled for uplink transmission. It can be that all the multiple frequency bands in the frequency band combination are in an activated state, but only one of the multiple frequency bands is scheduled for uplink transmission; or, it can be that only one of the multiple frequency bands in the frequency band combination is in an activated state, and the frequency band is scheduled for uplink transmission.

[0305] In some embodiments, the first information may be reported according to different frequency band combinations configured by the terminal.

[0306] In some embodiments, the reporting granularity of the first information may be per band combination.

[0307] Step S2203: The network device determines the configuration information of the uplink scheduling.

[0308] In some embodiments, the network device determines the configuration information of the uplink scheduling according to the power capability supported by the terminal when one frequency band of the frequency band combination is in an operating state.

[0309] In some embodiments, the power capability supported by the terminal when one frequency band of the frequency band combination is in an active state may indicate one of the following:

[0310] The terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in operation;

[0311] When a terminal is operating in one band of a band combination, it does not support single-band transmit power in one band.

[0312] It's worth noting that when configuring uplink scheduling, network equipment can fully consider the power capabilities of the terminal. If the terminal supports single-band transmit power in a frequency band combination when one band is active, the network equipment can configure transmit power based on the terminal's supported single-band transmit power; or, alternatively, configure uplink resources based on the terminal's supported single-band transmit power, thereby achieving maximum uplink coverage.

[0313] In some embodiments, the method further comprises:

[0314] The network device determines, based on the first information, whether the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0315] In some embodiments, the first information is used by the network device to determine whether the terminal supports single-band transmission power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0316] In some embodiments, the first information is used to indicate whether the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0317] In the above embodiment, the first information is used to indicate whether the terminal supports or does not support the power capability of single-band transmission power in a frequency band when a frequency band of the frequency band combination is in a working state, so that the network device can obtain the power capability of the terminal based on the information content of the first information, so that the network device can fully consider the power capability of the terminal when scheduling the transmission power of the terminal to achieve maximized uplink coverage.

[0318] In some embodiments, the network device determines, based on the first information, whether the terminal supports single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state, including one of the following:

[0319] determining, based on whether first information having a first value is received, whether the terminal supports single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state;

[0320] According to whether the first information and / or the third IE having the first value are received, it is determined whether the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0321] It is worth noting that there are two implementation methods for the network to determine whether the terminal supports single-band transmit power in one frequency band when the terminal is in an operating state in one frequency band of the frequency band combination.

[0322] In a first implementation manner, the network device may directly determine, based on whether first information having a first value is received, whether the terminal supports or does not support single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state.

[0323] It should be noted that the first information with the first value is used to indicate that the terminal supports single-band transmission power in a frequency band when one frequency band of the frequency band combination is in a working state; the first information with the second value is used to indicate that the terminal does not support single-band transmission power in a frequency band when one frequency band of the frequency band combination is in a working state.

[0324] In the second implementation method, the network device determines whether the terminal supports or does not support the single-band transmission power in a frequency band when a frequency band of the frequency band combination is in a working state based not only on whether the first information with the first value is received, but also on whether the third IE is received.

[0325] In the first implementation, the transmit power of the terminal in a frequency band of the frequency band combination depends only on the single-band transmit power of a frequency band indicated by the first IE, and is not related to the maximum transmit power of the frequency band combination indicated by the second IE or the maximum transmit power of a frequency band of the frequency band combination indicated by the third IE.

[0326] In some embodiments, determining, based on whether first information having a first value is received, whether the terminal supports single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state includes one of the following:

[0327] When the first information has a first value, determining that the terminal supports a single-band transmit power of one frequency band when one frequency band of the frequency band combination is in an operating state;

[0328] When the first information has the second value, it is determined that the terminal does not support single-band transmit power of one frequency band when one frequency band of the frequency band combination is in an operating state.

[0329] It should be noted that different information contents of the first information are respectively used to indicate whether the terminal supports or does not support single-band transmit power in a frequency band when one frequency band of the frequency band combination is in an operating state. If the network device receives first information with a first value sent by the terminal, it can be determined that the terminal supports single-band transmit power in a frequency band when one frequency band of the frequency band combination is in an operating state. If the network device receives first information with a second value sent by the terminal, it can be determined that the terminal does not support single-band transmit power in a frequency band when one frequency band of the frequency band combination is in an operating state.

[0330] It is worth noting that the method of determining whether the terminal supports the single-band transmission power in a frequency band when a frequency band of the frequency band combination is in a working state is directly based on the information content of the first information received by the network device. The transmission power of the terminal in a frequency band of the frequency band combination depends only on the single-band transmission power of a frequency band indicated by the first IE, and has nothing to do with the maximum transmission power of the frequency band combination indicated by the second IE and the maximum transmission power of a frequency band of the frequency band combination indicated by the third IE.

[0331] It can be understood that in this case, regardless of whether the network device receives the third IE, as long as the network device receives the first information with the first value, the network device can determine that the terminal supports single-band transmission power in one frequency band when one frequency band of the frequency band combination is in a working state.

[0332] In some embodiments, the method further comprises:

[0333] When receiving the first information having the first value, the network device determines the power configuration for uplink scheduling according to the first IE.

[0334] In some embodiments, the network device determines the power configuration of the uplink scheduling according to the first IE, including: configuring the transmit power according to the single-band transmit power indicated by the first IE.

[0335] It should be noted that when the network device receives the first information with a first value sent by the terminal, it can determine the single-band transmission power supported in a frequency band when a frequency band of the frequency band combination is in a working state; in this case, the network device can determine the maximum transmission power supported by the terminal in a frequency band when a frequency band of the frequency band combination is in a working state based on the single-band transmission power indicated by the first IE, so as to configure the transmission power according to the single-band transmission power indicated by the first IE, thereby reducing the situation where the terminal is over-constrained in power when performing single-band transmission on a frequency band of the frequency band combination.

[0336] In some embodiments, the method further comprises:

[0337] When receiving the first information having the second value, the network device determines the power configuration for uplink scheduling according to the first IE and the second IE.

[0338] It should be noted that when the network device receives the first information with the second value sent by the terminal, it can be determined that the single-band transmission power in a frequency band is not supported when one frequency band of the frequency band combination is in a working state; in this case, the maximum transmission power supported by one frequency band when the terminal is in a working state is not only limited by the single-band transmission power indicated by the first IE, but also by the maximum transmission power of the frequency band combination indicated by the second IE.

[0339] In some embodiments, upon receiving the first information having the second value, the network device may configure the transmit power of the terminal according to the minimum value between the maximum transmit power of the frequency band combination indicated by the second IE and the single frequency band transmit power indicated by the first IE.

[0340] In a second implementation, the network device determines whether the terminal supports single-band transmission power in a frequency band when a frequency band of the frequency band combination is in an operating state, not only depending on whether the first information with the first value is received, but also depending on whether the third IE is received.

[0341] In some embodiments, determining, based on whether first information and / or a third IE having a first value is received, whether the terminal supports single-band transmit power in a frequency band when a frequency band of the frequency band combination is in an operating state includes one of the following:

[0342] When the first information has a second value, determining that the terminal does not support single-band transmit power of one frequency band when one frequency band of the frequency band combination is in an operating state;

[0343] When the first information has the first value, it is determined whether the terminal supports single-band transmit power of one frequency band when one frequency band of the frequency band combination is in an operating state according to whether the third IE is received.

[0344] It should be noted that the first information with different values ​​is used to indicate whether the terminal supports or does not support single-band transmit power in a frequency band when one frequency band of the frequency band combination is in an operating state. If the network device receives the first information with the second value sent by the terminal, it can determine that the terminal does not support single-band transmit power in a frequency band when one frequency band of the frequency band combination is in an operating state. If the network device receives the first information with the first value sent by the terminal, it is necessary to further determine whether the terminal supports single-band transmit power in a frequency band when one frequency band of the frequency band combination is in an operating state based on whether the third IE is received.

[0345] In some embodiments, when the first information has the first value, determining, based on whether the third IE is received, whether the terminal supports single-band transmit power of a frequency band when a frequency band of the frequency band combination is in an operating state includes one of the following:

[0346] When the first information has the first value and the third IE is received, determining that the terminal does not support single-band transmit power of one frequency band when one frequency band of the frequency band combination is in an operating state;

[0347] When the first information has the first value and the third IE is not received, it is determined that the terminal supports single-band transmit power of one frequency band when one frequency band of the frequency band combination is in an operating state.

[0348] Since the third IE indicates the maximum transmit power supported by the terminal on each frequency band in the frequency band combination, when a frequency band combination using carrier aggregation is determined and only one frequency band in the frequency band combination is in working state, the priority of the third IE is higher than the priority of the first IE.

[0349] If the network device receives the first information with the first value sent by the terminal and does not receive the third IE, it can be determined that the terminal supports single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0350] If the network device receives the first information with the first value sent by the terminal and receives the third IE, it can be determined that the terminal does not support the single-band transmission power in one frequency band when one frequency band of the frequency band combination is in an operating state; in this case, the terminal supports the maximum transmission power on one frequency band of the frequency band combination when one frequency band of the frequency band combination is in an operating state.

[0351] In some embodiments, the method further comprises:

[0352] When the first information has the second value and the third IE is not received, the network device determines the power configuration of the uplink scheduling according to the first IE and the second IE;

[0353] When the first information has the second value and the third IE is received, the network device determines the power configuration of the uplink scheduling according to the second IE and the third IE.

[0354] It is worth noting that if the first information has the second value, it means that the terminal does not support single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state. In this case, when the network device determines the uplink scheduled power of the terminal, it needs to further determine whether the third IE is received.

[0355] It can be understood that since the third IE indicates the maximum transmit power of each frequency band of the frequency band combination, when the first information has the second value and the third IE is not received, the maximum transmit power supported by the terminal in one frequency band of the frequency band combination when the frequency band is in an operating state is limited by the single-band transmit power indicated by the first IE and the maximum transmit power of the frequency band combination indicated by the second IE.

[0356] In this case, the network device can configure the transmit power of the terminal according to the minimum value of the maximum transmit power of the frequency band combination indicated by the second IE and the single frequency band transmit power indicated by the first IE.

[0357] When the first information has the second value and the third IE is received, the maximum transmit power supported by the terminal in one frequency band of the frequency band combination when the frequency band is in an operating state is limited by the maximum transmit power of each frequency band in the frequency band combination indicated by the third IE and the maximum transmit power of the frequency band combination indicated by the second IE.

[0358] In this case, the network device can configure the transmit power of the terminal according to the minimum value of the maximum transmit power of the frequency band combination indicated by the second IE and the single frequency band transmit power indicated by the third IE.

[0359] In some embodiments, the method further comprises:

[0360] When the first information has the first value and the third IE is not received, the network device determines the power configuration of the uplink scheduling according to the first IE;

[0361] When the first information has the first value and the third IE is received, the network device determines the power configuration of the uplink scheduling according to the third IE.

[0362] It is worth noting that if the network device receives the first information having the first value and does not receive the third IE, it indicates that the terminal supports the single-band transmit power in one frequency band when one frequency band of the frequency band combination is in an operating state. In this case, the network device can determine the maximum transmit power supported by the terminal in one frequency band of the frequency band combination when the terminal is in an operating state based on the single-band transmit power indicated by the first IE, and configure the transmit power according to the single-band transmit power indicated by the first IE, thereby reducing the situation where the terminal is over-constrained in power when performing single-band transmission on one frequency band of the frequency band combination.

[0363] If the network device receives the first information with the first value and receives the third IE, it means that the terminal does not support the single-band transmission power in one frequency band when one frequency band of the frequency band combination is in working state; however, the terminal supports the maximum transmission power on one frequency band of the frequency band combination when one frequency band of the frequency band combination is in working state.

[0364] In this case, the network device can determine the maximum transmit power supported by a frequency band when the terminal is in a working state based on the maximum transmit power of each frequency band in the frequency band combination indicated by the third IE; and configure the transmit power according to the single-band transmit power indicated by the third IE to reduce the situation where the terminal is over-constrained in power when performing single-band transmission on a frequency band in the frequency band combination.

[0365] In some embodiments, the method further comprises one of the following:

[0366] The single-band transmit power supported by the terminal in a frequency band when one of the frequency band combinations is in an operating state, and when only one carrier is transmitting on a frequency band, the maximum transmit power supported by the terminal in a frequency band when one of the frequency band combinations is in an operating state is determined based on the single-band transmit power of the frequency band.

[0367] When a frequency band of the frequency band combination is in working state, the terminal supports single-band transmission power in a frequency band, and when multiple carriers are transmitted on a frequency band, the maximum transmission power supported by the terminal in a frequency band when a frequency band of the frequency band combination is in working state is determined according to the maximum transmission power of the carrier aggregation in the frequency band corresponding to the frequency band.

[0368] It is worth noting that carrier aggregation can include inter-band carrier aggregation and intra-band carrier aggregation, depending on the frequency band in which the carriers are aggregated. When a terminal is configured with intra-band carrier aggregation, multiple carriers are transmitted simultaneously on the corresponding frequency band.

[0369] When a frequency band of the frequency band combination is in an operating state and the terminal supports single-band transmission power in a frequency band, the terminal can select an appropriate transmission power according to the number of carriers actually transmitted on a frequency band.

[0370] The transmit power determination method involved in the embodiments of the present disclosure may include at least one of steps S2201 to S2203. For example, step S2201 may be implemented as an independent embodiment, and step S2201 combined with step S2203 may be implemented as an independent embodiment, but is not limited thereto.

[0371] In some embodiments, step S2201 and step S2202 may be executed in an interchanged order or simultaneously.

[0372] In some embodiments, step S2202 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that when a frequency band of the frequency band combination is in an operating state, the terminal does not support single-band transmit power in the frequency band, and the terminal may not send the first information to the network device.

[0373] In some embodiments, step S2202 and step S2203 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that when the terminal does not have uplink transmission, the network device does not need to determine the configuration information of the uplink scheduling.

It is understood that when a frequency band of the frequency band combination is in an operating state, the terminal does not support single-band transmit power in the frequency band, and the terminal may not send the first information to the network device.

[0460] One band of the band combination is active;

[0461] There is uplink scheduling on one frequency band of the frequency band combination.

[0462] FIG5 is an interactive diagram illustrating a method for determining transmit power according to an exemplary embodiment. As shown in FIG5 , the embodiment of the present disclosure relates to a method for determining transmit power, which is used in a communication system 100 and includes one of the following steps:

[0463] Step S5101: The terminal sends first information to the network device.

[0464] In some embodiments, the first information is used by the network device to determine whether the terminal supports single-band transmission power in one frequency band when one frequency band of the frequency band combination is in an operating state.

[0465] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, network device side, etc. embodiments, which will not be repeated here.

[0466] In some embodiments, as shown in Table 1, the power configuration of the terminal in single frequency band and frequency band combination cases.

[0467] Table 1

[0468] Among them, for the power configuration of the frequency band combination (such as CA_nXA-nYA), that is, the case where there is a single carrier on each frequency band, its total power capability is limited by the power level reported by the frequency band combination (for example, powerClass, powerClass-v1610); at the same time, the power on each frequency band, that is, nX and nY, cannot exceed the power level reported by its single frequency band (for example, ue-PowerClass, ue-PowerClass-v1610, ue-PowerClass-v1700).

[0469] If the terminal also reports the power level of each frequency band in the frequency band combination (for example, ue-PowerClassPerBandPerBC-r17), the maximum power of each frequency band cannot exceed the power level corresponding to ue-PowerClassPerBandPerBC-r17.

[0470] From the above, it can be seen that if the terminal is configured with a frequency band combination, even if only a single frequency band is transmitted during the actual transmission process (for example, only one component carrier is activated), its total power is still limited by the power level reported by the frequency band combination (for example, powerClass, powerClass-v1610), which may cause the power on the frequency band to be over-constrained.

[0471] For example, if band X reports ue-PowerClass as PC2, but the band combination that includes band X reports powerClass as PC3, even if band X is the only band in the combination operating (for example, if other bands are deactivated), the power of band X will be limited to PC3. This will affect the uplink coverage of band X and thus affect communication performance.

[0472] Based on this, the embodiments of the present disclosure introduce a new terminal capability, which can select an appropriate power level according to the actual transmission situation of the terminal, thereby avoiding the above-mentioned over-constraint problem.

[0473] In some embodiments, a new terminal capability may be introduced, for example, enablepowerclassexception, which indicates whether the terminal is allowed to transmit in a band combination configuration when only a single band is transmitting, and its maximum power depends only on:

[0474] (1) IE ue-PowerClass reported on a single frequency band, when only one carrier is transmitting on that frequency band;

[0475] (2) IE powerClass reported by the frequency band combination, when multiple carriers are transmitting simultaneously on the frequency band.

[0476] Example embodiment 1:

[0477] A new terminal capability can be introduced, for example, enablepowerclassexception, which indicates whether the terminal is allowed to transmit only on a single band in a band combination configuration, and its maximum power depends only on the IE ue-PowerClass reported by the single band.

[0478] Here, when only a single frequency band is transmitting, it means that other frequency bands are in a deactivated state; or, it means that only one frequency band is scheduled for uplink transmission.

[0479] Terminal capabilities are reported based on different frequency band combinations, that is, the reporting granularity is per band combination.

[0480] For example, as shown in Table 2, the terminal reports the following information.

[0481] Table 2

[0482] When enablepowerclassexception=0 or does not exist, when the terminal is configured for CA_nX-nY carrier aggregation, the maximum power on its single frequency band, such as nX or nY, depends on min{IE ue-PowerClass, IE powerClass} or IE ue-PowerClassPerBandPerBC.

[0483] When enablepowerclassexception=1, when the terminal is configured for CA_nX-nY carrier aggregation, the maximum power on its single frequency band, such as nX or nY, depends only on the IE ue-PowerClass, that is, it is not related to the IE powerClass and the IE ue-PowerClassPerBandPerBC.

[0484] In another case, if the IE ue-PowerClassPerBandPerBC is also reported on the frequency band, the maximum power on the single frequency band depends on the IE ue-PowerClassPerBandPerBC. Based on this, when the terminal's power configuration is as shown in Table 2, when nX and nY in CA_nX-nY carrier aggregation only transmit on a single frequency band, for example, nX transmits and nY is deactivated, or nY transmits and nX is deactivated, the maximum power supported by the terminal is as shown in Table 3.

[0485] Table 3

[0486] Example embodiment 2:

[0487] The above terminal capabilities also apply to intra-band carrier aggregation band combinations. However, in an intra-band band combination, when only a single band is transmitted, only a single carrier is transmitted.

[0488] For example, the single-band IE ue-PowerClass for nX reports PC2, while in the case of intra-band carrier aggregation, the corresponding IE powerClass for nXC reports PC3. When nX in the intra-band frequency band combination transmits only a single carrier, the maximum power supported by the terminal is shown in Table 4.

[0489] Table 4

[0490] Example embodiment 3:

[0491] The above terminal capabilities also apply to frequency band combinations where inter-band carrier aggregation is included. As shown in Table 5, the terminal reports the following information:

[0492] Table 5

[0493] When enablepowerclassexception=0 or does not exist, when the terminal is configured for CA_nX-nY carrier aggregation, the maximum power on its single frequency band, such as nX or nY, depends on min{IE ue-PowerClass, IE powerClass} or IE ue-PowerClassPerBandPerBC.

[0494] When enablepowerclassexception=1, when the terminal is configured for CA_nX-nY carrier aggregation, the maximum power on its single frequency band, such as nX or nY, depends only on the IE ue-PowerClass, that is, it is not related to the IE powerClass and the IE ue-PowerClassPerBandPerBC.

[0495] In another case, if the IE ue-PowerClassPerBandPerBC is also reported on the frequency band, the maximum power on the single frequency band depends on the IE ue-PowerClassPerBandPerBC.

[0496] When enablepowerclassexception = 0 or does not exist, when the terminal is configured for CA_nXA-nYC carrier aggregation, there is same-band continuous carrier aggregation (for example, nYC) on its single frequency band. The maximum power of the carrier aggregation on its single frequency band depends on the power reported during the same-band carrier aggregation, that is, it depends on min{IE powerClass for inter-band, IE powerClass for intra-band}.

[0497] When enablepowerclassexception = 1, when the terminal is configured for CA_nXA-nYC carrier aggregation, there is same-band continuous carrier aggregation (for example, nYC) on its single frequency band. The maximum power of the carrier aggregation on its single frequency band depends on the IE powerClass for intra-band reported during the same-band carrier aggregation.

[0498] Based on this, when the power configuration of the terminal is as shown in Table 5, when nX and nY in the CA_nX-nY carrier aggregation have only single-band transmission or when there is transmission in the same-band continuous carrier aggregation nYC in the CA_nXA-nYC carrier aggregation, the maximum power supported by the terminal is as shown in Table 6.
