Fig. 2A is an interactive schematic diagram illustrating a transmit power determination method according to an exemplary embodiment. As shown in fig. 2A, embodiments of the present disclosure relate to a transmit power determination method for a communication system 100, the method comprising:

step S2101: the terminal sends the second information to the network device.

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

In some embodiments, the terminal may be various types of communication devices. The terminal may be a mobile terminal or a fixed terminal. For example, the terminal may be a cell phone, tablet computer, smart office device, smart home device, vehicle-mounted device, and/or flying device.

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

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

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

In some embodiments, the power level may be used to indicate the maximum transmit power supported by the terminal.

It should be noted that, the transmission Power of the terminal may be generally defined based on a Power Class (PC), that is, the maximum transmission Power of the terminal cannot exceed the transmission Power upper limit value corresponding to the Power Class of the terminal.

In some embodiments, the second information includes at least one of:

A first information element (Information Element, IE) for indicating a single-band maximum transmit power for each band of the terminal;

And a third IE for indicating a maximum transmit power for each frequency band in the frequency band combination.

In some embodiments, the first IE may be used to carry a power level of each of a plurality of 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.

Note 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.

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

In some embodiments, the second IE may be used to carry a power level of each of a plurality of frequency band combinations supported by the terminal; that is, the terminal may report the power level of each band combination (per band combination) supported by the terminal to the network device through the second IE.

Note that the power level carried by the second IE may be the power level of the band combination level; the power class of the band combination class indicates the maximum transmit power over the band combination. That is, the sum of the transmission powers of the terminals in the respective frequency bands of the frequency band combination should be less than or equal to the maximum transmission power of the frequency band combination indicated by the power class corresponding to the frequency band combination.

In some embodiments, the second IE may be powerClass.

In some embodiments, the third IE may be used to carry power levels of respective frequency bands within each of a plurality of frequency band combinations supported by the terminal; that is, the terminal may report the power level of each frequency band (per band per band Combination) within each frequency band combination supported by the terminal to the network device through the third IE.

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

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

Step S2102: the terminal sends first information to the network device.

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

In some embodiments, the first information and the second information may be carried within the same message.

Note that the terminal may carry the first information and the second information in the same message, so that the first information and the second information are simultaneously transmitted to the network device by transmitting the message to the network device.

In some embodiments, the first information and the second information may be carried within different messages.

In some embodiments, the first information is used for determining, by the network device, whether the terminal supports single-band transmission power in one band when the one band of the band combination is in an operating state.

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

Note that, in the case where the terminal is configured with carrier aggregation and determines to use one band combination of carrier aggregation, if only one band within the band combination is in an operating state, the terminal may determine whether the first information needs to be transmitted to the network device according to the power capability of supporting or not supporting the single-band transmission power in one band when the one band of the band combination is in the operating state. Therefore, the first information can be utilized to inform the network device of the power capability of the terminal supporting or not supporting the single-band transmission power in one frequency band when the frequency band of the frequency band combination is in a working state, so that the network device can fully consider the power capability of the terminal when the transmission power of the terminal is scheduled, and the maximum uplink coverage is realized.

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

Note that, when the terminal supports the single-band transmission power in one band while the one band of the band combination is in the operating state, it is understood that the maximum transmission power allowed by the terminal to perform single-band transmission in the one band of the band combination configured by carrier aggregation depends on the single-band maximum transmission power corresponding to the one band.

In general, if a terminal configures a frequency band combination, no matter whether the terminal performs single-band transmission or multi-band transmission on one frequency band of the frequency band combination, the network device considers the maximum transmission power of the frequency band combination reported by the terminal when configuring the transmission power for the terminal. That is, even if the terminal performs single-band transmission on one band of the band combination, its transmission power may be limited by the maximum transmission power of the band combination, so that the transmission power is over-constrained when the terminal performs single-band transmission on one band of the band combination.

In the embodiment of the disclosure, if the terminal supports the single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in the working state, the maximum transmitting power of the terminal may depend only on the single-band maximum transmitting power corresponding to the one frequency band and is irrelevant to the maximum transmitting power of the frequency band combination under the condition that the terminal performs single-band transmitting on the one frequency band of the frequency band combination; therefore, the proper power level can be selected according to the actual transmitting condition of the terminal configured with the frequency band combination, so as to avoid the problem of over-constraint of transmitting power.

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

And when one frequency band of the frequency band combination is in a working state, the terminal supports single-band transmitting power of the one frequency band and sends first information to the network equipment.

It can be understood that, in the case that the maximum transmission power when the terminal allows the single-band transmission in one band of the band combination configured by carrier aggregation depends on the single-band maximum transmission power corresponding to the one 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.

In other embodiments, the method further comprises:

When one frequency band of the frequency band combination is in a working state, the terminal does not support single-band transmitting power of the one frequency band and does not send first information to the network equipment.

It may be appreciated that, in a case where the maximum transmission power when the terminal does not allow the single-band transmission in one band of the band combination configured by the carrier aggregation depends on the single-band maximum transmission power corresponding to the one band, the terminal does not transmit the first information to the network device. When the network device configures the transmitting power for the terminal, the network device can determine the transmitting power of the terminal according to the maximum transmitting power of the frequency band combination reported by the terminal.

In some embodiments, one frequency band of the frequency band combination is in an operational state, including at least one of:

One frequency band of the frequency band combination is in an activated state;

One frequency band of the frequency band combination is provided with uplink scheduling.

Note that when one frequency band of the frequency band combination is in an active state, it is understood that only one frequency band of the plurality of frequency bands within the frequency band combination is in an active state, and the other frequency bands are in a deactivated state.

The fact that one frequency band of the frequency band combination has uplink scheduling is understood as that only one frequency band of a plurality of frequency bands in the frequency band combination is scheduled to transmit uplink.

It should be noted that, only one frequency band is scheduled to transmit uplink in the frequency band combination, and the multiple frequency bands in the frequency band combination are all in an activated state, but only one frequency band in the multiple frequency bands is scheduled to transmit uplink; or only one frequency band in a plurality of frequency bands combined by the frequency bands is in an activated state, and the frequency band is scheduled to be transmitted in an uplink mode.

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

In some embodiments, the reporting granularity of the first information may be per-band combination (per band combination).

Step S2103: the network device determines configuration information of the uplink schedule.

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

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

the terminal supports single-frequency-band transmitting power in one frequency band when the frequency band of the frequency band combination is in a working state;

The terminal does not support single-band transmitting power in one frequency band when the frequency band of the frequency band combination is in an operating state.

Note that the power capability of the terminal may be fully considered when the network device performs the configuration of the uplink schedule. If the terminal supports single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state, the network equipment can configure the transmitting power according to the single-band transmitting power supported by the terminal; or configuring uplink resources based on single-band transmitting power supported by the terminal; thereby achieving maximum uplink coverage.

In some embodiments, the method further comprises:

the network device determines whether the terminal supports single-band transmission power in one frequency band when the one frequency band of the frequency band combination is in an operating state.

In some embodiments, the network device determines whether the terminal supports single-band transmission power in one band when the one band of the band combination is in an operating state according to whether the first information is received.

In the above embodiment, the first information is limited to indicate that the terminal supports the single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in the working state, so that the network device can obtain the power capability of the terminal that the terminal supports or does not support the single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in the working state according to whether the first information is received, thereby effectively reducing signaling overhead.

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

According to whether the first information is received, whether the terminal supports single-frequency-band transmitting power in one frequency band when the frequency band of the frequency band combination is in a working state is determined;

and determining whether the terminal supports single-band transmitting power in one frequency band when the frequency band of the frequency band combination is in an operating state according to whether the first information and/or the third IE are received.

It is worth noting that there are two implementations of the network in determining whether a terminal supports single-band transmit power in one band when the one band of the band combination is in operation.

In the first implementation manner, the network device may determine, directly according to whether the first information is received, whether the terminal supports or does not support single-band transmission power in one frequency band when the one frequency band of the frequency band combination is in a working state.

In a second implementation manner, the network device determines whether the terminal supports or does not support the single-band transmission power in one frequency band when the one frequency band of the frequency band combination is in an operating state according to whether the first information is received or not and whether the third IE is received or not.

In a first implementation, the transmission power of the terminal in one frequency band of the frequency band combination is only dependent on the single-frequency band transmission power of the one frequency band indicated by the first IE, and is independent of the maximum transmission power of the frequency band combination indicated by the second IE and the maximum transmission power of the one frequency band of the frequency band combination indicated by the third IE.

In some embodiments, determining whether the terminal supports single-band transmission power in one band when the one band of the band combination is in an operating state according to whether the first information is received includes:

When first information is received, determining that a terminal supports single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state; or alternatively

And when the first information is not received, determining that the terminal does not support single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state.

It should be noted that, the first information is used to indicate that the terminal supports the single-band transmitting power in one frequency band when the 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 can be determined that the terminal supports single-band transmitting power in one band when the one band of the band combination is in a working state. If the network device does not receive the first information sent by the terminal, it may be determined that the terminal does not support single-band transmission power in one band when the one band of the band combination is in an operating state.

The value is that, directly according to whether the network device receives the first information, whether the terminal supports the single-band transmission power of one band when the one band of the band combination is in an operating state is determined, the transmission power of the terminal in the one band of the band combination only depends on the single-band transmission power of the one band indicated by the first IE, and is irrelevant to the maximum transmission power of the band combination indicated by the second IE and the maximum transmission power of the one band of the band combination indicated by the third IE.

It will be appreciated that in this case, whether the network device receives the third IE or not, as long as the network device receives the first information, the network device may determine that the terminal supports single-band transmission power in one band when the one band of the band combination is in an operating state.

In some embodiments, the method further comprises:

And when the first information is received, the network equipment determines the power configuration of the uplink scheduling according to the first IE.

In some embodiments, the network device determines a power configuration of the uplink schedule according to the first IE, including: and configuring the transmitting power according to the single-band transmitting power indicated by the first IE.

When the network device receives the first information sent by the terminal, it can determine that the single-band transmitting power of one band is supported when the one band of the band combination is in the working state; in this case, the network device may determine, according to the single-band transmission power indicated by the first IE, a maximum transmission power supported by the terminal in the one band when the one band of the band combination is in the operating state, so as to configure the transmission power according to the single-band transmission power indicated by the first IE, thereby reducing a power overconstrained condition when the terminal performs single-band transmission on the one band of the band combination.

In some embodiments, the method further comprises:

And when the first information is not received, the network equipment determines the power configuration of the uplink scheduling according to the first IE and the second IE.

It should be noted that, when the network device does not receive the first information sent by the terminal, it may determine that the single-band transmitting power in one band is not supported when the one band of the band combination is in the working state; in this case, the maximum transmission power supported by the terminal in one frequency band of the frequency band combination is limited not only by the single frequency 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 when the one frequency band of the frequency band combination is in an operating state.

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

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

In some embodiments, according to whether the first information and/or the third IE are received, determining whether the terminal supports single-band transmission power in one frequency band when the one frequency band of the frequency band combination is in an operating state, including one of the following:

When the first information is not received, determining that the terminal does not support single-frequency-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state;

It should be noted that, the first information is used to indicate that the terminal supports the single-band transmitting power in one frequency band when the 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 be determined that the terminal does not support single-band transmission power in one band when the one band of the band combination is in an operating state. If the network device receives the first information sent by the terminal, it needs to determine whether the terminal supports the single-band transmitting power in one band when the one band of the band combination is in the working state according to whether the third IE is received.

In some embodiments, when the first information is received, determining whether the terminal supports a single-band transmission power of one band when the one band of the band combination is in an operating state according to whether a third IE is received, including one of the following:

When the first information is received and the third IE is not received, determining that the terminal supports single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state;

When the first information is received and the third IE is received, determining that the terminal does not support single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in an operating state.

Since the third IE indicates the maximum transmit power supported by the terminal on each frequency band in the frequency band combination, the priority of the third IE is higher than the priority of the first IE when it is determined that one frequency band combination using carrier aggregation is in an operating state and only one frequency band in the frequency band combination.

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

If the network equipment receives the first information sent by the terminal and receives the third IE, the network equipment can determine that the terminal does not support single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state; in this case, the terminal supports the maximum transmission power on one frequency band of the frequency band combination when the one frequency band of the frequency band combination is in an operating state.

In some embodiments, the method further comprises:

When the first information is not received and the third IE is not received, the network equipment determines the power configuration of uplink scheduling according to the first IE and the second IE;

and when the first information is not received and the third IE is received, the network equipment determines the power configuration of the uplink scheduling according to the second IE and the third IE.

Note that if the network device does not receive the first information, it indicates that the terminal does not support the single-band transmission power in one frequency band when the 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.

It can be appreciated that since the third IE indicates the maximum transmit power for each frequency band of the frequency band combination. And under the condition that the first information is not received and the third IE is not received, the maximum transmission power supported by the terminal in one frequency band is limited by the single-frequency band transmission power indicated by the first IE and the maximum transmission power of the frequency band combination indicated by the second IE when the terminal is in an operating state in one frequency band of the frequency band combination.

In this case, the network device may configure the transmission power of the terminal according to the minimum value of the maximum transmission power of the band combination indicated by the second IE and the single-band transmission power indicated by the first IE.

And under the condition that the first information is not received and the third IE is received, when one frequency band of the frequency band combination is in an operating state, the maximum transmission power supported by the one frequency band of the terminal is limited by the maximum transmission power of each frequency band in the frequency band combination indicated by the third IE and the maximum transmission power of the frequency band combination indicated by the second IE.

In this case, the network device may configure the transmission power of the terminal according to the minimum value of the maximum transmission power of the band combination indicated by the second IE and the single-band transmission power indicated by the third IE.

In some embodiments, the method further comprises:

when the first information is received and the third IE is not received, the network equipment determines the power configuration of uplink scheduling according to the first IE;

and when the first information is received and the third IE is received, the network equipment determines the power configuration of the uplink scheduling according to the third IE.

Note that if the network device receives the first information and does not receive the third IE, it indicates that the terminal supports single-band transmission power in one band when the one band of the band combination is in an operating state. In this case, the network device may determine, according to the single-band transmission power indicated by the first IE, a maximum transmission power supported by the terminal in the one band when the one band of the band combination is in the operating state, so as to configure the transmission power according to the single-band transmission power indicated by the first IE, thereby reducing a power overconstrained condition when the terminal performs single-band transmission on the one band of the band combination.

If the network equipment receives the first information and receives the third IE, the terminal is not supported by the single-frequency-band transmitting power of one frequency band when the one frequency band of the frequency band combination is in a working state; the terminal supports maximum transmit power over one of the frequency bands of the frequency band combination when the one of the frequency bands of the frequency band combination is in an operational state.

In this case, the network device may determine, according to the maximum transmission power of each frequency band in the frequency band combination indicated by the third IE, the maximum transmission power supported by one frequency band of the frequency band combination when the one frequency band of the frequency band combination is in the working state; and configuring the transmitting power according to the single-band transmitting power indicated by the third IE, so as to reduce the power over-constraint condition when the terminal transmits the single band on one frequency band of the frequency band combination.

In some embodiments, the method further comprises one of:

When one frequency band of the frequency band combination is in an operating state, the terminal supports single-band transmitting power of the one frequency band, and when only one carrier wave transmits on the one frequency band, the maximum transmitting power supported by the terminal in the operating state of the one frequency band of the frequency band combination is determined according to the single-band transmitting power of the one frequency band;

when one frequency band of the frequency band combination is in an operating state, the terminal supports single-frequency band transmitting power of the one frequency band, and when a plurality of carriers are transmitted on the one frequency band, the maximum transmitting power supported by the terminal in the one frequency band is determined according to the maximum transmitting power of carrier aggregation in the frequency band corresponding to the one frequency band.

Note that, depending on the frequency Band in which the carrier aggregation is located, the carrier aggregation may include inter-Band (inter-Band) carrier aggregation and intra-Band (intra-Band) carrier aggregation. When the terminal is configured with intra-Band carrier aggregation, the terminal simultaneously transmits a plurality of carriers on the corresponding frequency Band.

Under the condition that the terminal supports single-band transmitting power in one frequency band when the frequency band of the frequency band combination is in a working state, proper transmitting power can be selected according to the number of carriers actually transmitted in the frequency band.

In some embodiments, the term "information" may be interchangeable with terms of "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", "data", etc.

In some embodiments, the term "send" may be interchangeable with terms of "transmit," "report," "transmit," and the like.

The transmission power determining method according to the embodiments of the present disclosure may include at least one of step S2101 to step S2103. For example, step S2101 may be implemented as a separate embodiment, and step S2101 in combination with step S2103 may be implemented as a separate embodiment, but is not limited thereto.

In some embodiments, step S2101 and step S2102 may be performed in exchange for one another or simultaneously.

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

In some embodiments, steps S2102, S2103 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It can be appreciated that in the case where the terminal does not have uplink transmissions, the network device does not need to determine configuration information for uplink scheduling.

Fig. 2B is an interactive schematic diagram illustrating a method of determining transmit power according to an exemplary embodiment. As shown in fig. 2B, embodiments of the present disclosure relate to a transmit power determination method for a communication system 100, the method comprising:

Step S2201: the terminal sends the second information to the network device.

In some embodiments, the optional implementation of step S2201 may refer to the optional implementation of step S2101 of fig. 2A, and other relevant parts in the embodiment related to fig. 2A, which are not described herein.

Step S2202: the terminal sends first information to the network device.

And sending first information to the network equipment according to whether the terminal supports single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state.

Note that, in the case where the terminal is configured with carrier aggregation and determines to use one band combination of carrier aggregation, if only one band within the band combination is in an operating state, the terminal may transmit the first information to the network device according to the power capability of supporting or not supporting the single-band transmission power in one band when the one band of the band combination is in the operating state. Therefore, the power capability of the single-frequency band transmitting power supported or not supported in one frequency band when the terminal is in a working state in the frequency band combination can be informed to the network equipment by utilizing different information contents carried by the first information, so that the network equipment can fully consider the power capability of the terminal when the transmitting power of the terminal is scheduled, and the maximum uplink coverage is realized.

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

It can be understood that the terminal can send the first information to the network device to inform the network device by using the first information, and whether the terminal supports the single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state, so that the network device can conveniently determine the maximum transmitting power of the terminal for transmitting the single-band in the one frequency band of the frequency band combination.

It should be noted that the first information may include one or more indication bits, and different bit values of the indication bits are used to indicate whether the terminal supports the single-band transmission power in one frequency band when the one frequency band of the frequency band combination is in an operating state. Note that each indication bit corresponds to one band combination of the carrier aggregation configuration.

In some embodiments, the first information having a first value is used to instruct the terminal to support the single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in an operating state;

And the first information with the second value is used for indicating that the terminal does not support single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in an operating state.

Here, the first value and the second value may be different bit values of the indication bit; specific values of the first value and the second value may be set according to actual requirements, which is not limited in the embodiments of the present disclosure. In some embodiments, the first value may be 1 and the second value may be 0.

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

When one frequency band of the frequency band combination is in a working state, the terminal supports single-band transmitting power of the one frequency band and sends first information with a first value to the network equipment;

When one frequency band of the frequency band combination is in a working state, the terminal does not support single-band transmitting power in the one frequency band, and sends first information with a second value to the network equipment.

It should be noted that, when the terminal supports the single-band transmission power in one band when the one band of the band combination is in the working state, it is understood that the maximum transmission power allowed by the terminal to perform single-band transmission in the one band of the band combination configured by carrier aggregation depends on the maximum transmission power of the single-band corresponding to the one band.

Based on this, in the embodiment of the disclosure, when the terminal supports the single-band transmitting power in one band when the one band of the band combination is in the working state, the terminal sends the first information with the first value to the network device, so that the network device configures the transmitting power for the terminal when the terminal performs the single-band transmitting on the one band of the band combination according to the single-band maximum transmitting power of each band supported by the terminal.

Under the condition that the terminal does not allow the maximum transmitting power when the terminal performs single-band transmission in one frequency band of the frequency band combination configured by carrier aggregation to depend on the single-band maximum transmitting power corresponding to the one frequency band, the terminal can send first information with a second value to the network equipment, so that the network equipment configures the transmitting power for the terminal according to the maximum transmitting power of the frequency band combination supported by the terminal.

Thus, the maximum transmitting power of the terminal for transmitting the single frequency band on one frequency band of the frequency band combination is related to the maximum transmitting power of the single frequency band of the frequency band actually transmitted by the terminal, and is not related to the maximum transmitting power of the frequency band combination; therefore, the proper power level can be selected according to the actual transmitting condition of the terminal configured with the frequency band combination, so as to avoid the problem of over-constraint of transmitting power.

One frequency band of the frequency band combination is in an activated state;

Step S2203: the network device determines configuration information of the uplink schedule.

In some embodiments, the method further comprises:

And the network equipment determines whether the terminal supports single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state according to the first information.

In the above embodiment, the first information is used to indicate the power capability of the terminal that supports or does not support the single-band transmission power in one frequency band when the one frequency band of the frequency band combination is in the working state, so that the network device can obtain the power capability of the terminal according to the information content of the first information, so that the power capability of the terminal can be fully considered when the network device schedules the transmission power of the terminal, and the maximum uplink coverage is realized.

In some embodiments, the network device determines, according to the first information, whether the terminal supports single-band transmission power in one band when the one band of the band combination is in an operating state, including one of:

according to whether first information with a first value is received or not, whether the terminal supports single-frequency-band transmitting power in one frequency band when the frequency band of the frequency band combination is in a working state or not is determined;

And determining whether the terminal supports single-band transmitting power in one frequency band when the frequency band of the frequency band combination is in a working state according to whether first information and/or third IE with a first value are received.

In a first implementation manner, the network device may determine, directly according to whether the first information with the first value is received, whether the terminal supports or does not support single-band transmission power in one frequency band when the one frequency band of the frequency band combination is in a working state.

It should be noted that, the first information with the first value is used to instruct the terminal to support the single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in the working state; the first information with the second value is used for indicating that the terminal does not support the single-frequency-band transmitting power in one frequency band when the frequency band of the frequency band combination is in a working state.

In a second implementation manner, the network device determines whether the terminal supports or does not support the single-band transmission power in one frequency band when the one frequency band of the frequency band combination is in an operating state according to whether the first information with the first value is received or not and whether the third IE is received or not.

In some embodiments, determining whether the terminal supports single-band transmission power in one band when the one band of the band combination is in an operating state according to whether first information with a first value is received, includes one of:

when the first information has the second value, determining that the terminal does not support single-frequency-band transmitting power of one frequency band when the frequency band of the frequency band combination is in a working state.

It should be noted that, different information contents of the first information are respectively used for indicating that the terminal supports or does not support the single-band transmitting power in one frequency band when the frequency band of the frequency band combination is in a working state. If the network device receives the first information with the first value sent by the terminal, it can be determined that the terminal supports single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state. If the network device receives the first information with the second value sent by the terminal, it can be determined that the terminal does not support single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state.

The value is that, directly according to the information content of the first information received by the network device, whether the terminal supports the single-band transmission power of one band when the one band of the band combination is in the working state is determined, the transmission power of the terminal in the one band of the band combination only depends on the single-band transmission power of the one band indicated by the first IE, and is irrelevant to the maximum transmission power of the band combination indicated by the second IE and the maximum transmission power of the one band of the band combination indicated by the third IE.

It may be appreciated that in this case, whether the network device receives the third IE or not, as long as the network device receives the first information having the first value, the network device may determine that the terminal supports the single-band transmission power in one band when the one band of the band combination is in an operating state.

In some embodiments, the method further comprises:

And when receiving the first information with the first value, the network equipment determines the power configuration of the uplink scheduling according to the first IE.

When the network device receives the first information with the first value sent by the terminal, the network device can determine single-band transmitting power supported in one frequency band when the one frequency band of the frequency band combination is in a working state; in this case, the network device may determine, according to the single-band transmission power indicated by the first IE, a maximum transmission power supported by the terminal in the one band when the one band of the band combination is in the operating state, so as to configure the transmission power according to the single-band transmission power indicated by the first IE, thereby reducing a power overconstrained condition when the terminal performs single-band transmission on the one band of the band combination.

In some embodiments, the method further comprises:

and when the first information with the second value is received, the network equipment determines the power configuration of the uplink scheduling according to the first IE and the second IE.

When the network device receives the first information with the second value sent by the terminal, it can determine that the single-band transmitting power of one frequency band is not supported when the one frequency band of the frequency band combination is in a working state; in this case, the maximum transmission power supported by the terminal in one frequency band of the frequency band combination is limited not only by the single frequency 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 when the one frequency band of the frequency band combination is in an operating state.

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 a minimum value of the maximum transmit power of the band combination indicated by the second IE and the single-band transmit power indicated by the first IE.

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

In some embodiments, according to whether the first information and/or the third IE having the first value are received, determining whether the terminal supports single-band transmission power in one frequency band when the one frequency band of the frequency band combination is in an operating state, including one of the following:

When the first information has a second value, determining that the terminal does not support single-frequency-band transmitting power of one frequency band when the one frequency band of the frequency band combination is in a working state;

when the first information has a first value, whether the terminal supports single-frequency-band transmitting power of one frequency band when the frequency band of the frequency band combination is in a working state is determined according to whether the third IE is received.

It should be noted that, the first information with different values is used to indicate that the terminal supports or does not support the single-band transmitting power in one frequency band when the frequency band of the frequency band combination is in the working state. If the network device receives the first information with the second value sent by the terminal, it can be determined that the terminal does not support single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state. If the network device receives the first information with the first value sent by the terminal, on the basis of the first information, whether the terminal supports single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state is determined according to whether the third IE is received or not.

In some embodiments, when the first information has the first value, determining whether the terminal supports the single-band transmission power of one band when the one band of the band combination is in the operating state according to whether the third IE is received, where the determining includes one of:

When the first information has a first value and a third IE is received, determining that the terminal does not support single-frequency-band transmitting power of one frequency band when the one frequency band of the frequency band combination is in a working state;

And when the first information has a first value and the third IE is not received, determining that the terminal supports single-frequency-band transmitting power of one frequency band when the frequency band of the frequency band combination is in a working state.

If the network device receives the first information with the first value sent by the terminal and does not receive the third IE, the network device can determine that the terminal supports single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state.

If the network equipment receives the first information with the first value sent by the terminal and receives the third IE, the network equipment can determine that the terminal does not support single-band transmitting power in one frequency band when the one frequency band of the frequency band combination is in a working state; in this case, the terminal supports the maximum transmission power on one frequency band of the frequency band combination when the one frequency band of the frequency band combination is in an operating state.

In some embodiments, the method further comprises:

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

And when the first information has the second value and the third IE is received, the network equipment determines the power configuration of the uplink scheduling according to the second IE and the third IE.

Note that if the first information has the second value, it indicates that the terminal does not support the single-band transmission power in one band when the one band of the band combination is in the working 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.

It can be appreciated that since the third IE indicates the maximum transmit power for each frequency band of the frequency band combination. And under the condition that the first information has a second value and the third IE is not received, the maximum transmission power supported by the terminal in one frequency band is limited by the single-frequency band transmission power indicated by the first IE and the maximum transmission power of the frequency band combination indicated by the second IE when the one frequency band of the frequency band combination is in an operating state.

Under the condition that the first information has the second value and the third IE is received, when one frequency band of the frequency band combination is in a working state, the maximum transmission power supported by the one frequency band is limited by the maximum transmission power of each frequency band in the frequency band combination indicated by the third IE and the maximum transmission power of the frequency band combination indicated by the second IE.

In some embodiments, the method further comprises:

when the first information has a first value and the third IE is not received, the network equipment determines the power configuration of uplink scheduling according to the first IE;

and when the first information has the first value and the third IE is received, the network equipment determines the power configuration of the uplink scheduling according to the third IE.

Note that if the network device receives the first information with the first value and does not receive the third IE, it indicates that the terminal supports the single-band transmission power in one band when the one band of the band combination is in the working state. In this case, the network device may determine, according to the single-band transmission power indicated by the first IE, a maximum transmission power supported by the terminal in the one band when the one band of the band combination is in the operating state, so as to configure the transmission power according to the single-band transmission power indicated by the first IE, thereby reducing a power overconstrained condition when the terminal performs single-band transmission on the one band of the band combination.

If the network equipment receives the first information with the first value and receives the third IE, the terminal is not supported by the single-frequency-band transmitting power of one frequency band when the frequency band of the frequency band combination is in a working state; the terminal supports maximum transmit power over one of the frequency bands of the frequency band combination when the one of the frequency bands of the frequency band combination is in an operational state.

In some embodiments, the method further comprises one of:

Fig. 5 is an interactive schematic diagram illustrating a transmit power determination method according to an exemplary embodiment. As shown in fig. 5, embodiments of the present disclosure relate to a transmit power determination method for a communication system 100, the method comprising one of the following steps:

Step S5101: the terminal sends first information to the network device.

In some embodiments, the method may include the method of the embodiments of the communication system side, the terminal side, the network device side, and the like, which are not described herein.

In some embodiments, as shown in table 1, the power configuration of the terminal is in the case of single band and band combination.

TABLE 1

Wherein, for the power configuration of the band combination (e.g., ca_ nXA-nYA), i.e., where each band is single carrier, the total power capability is limited by the power class reported by the band combination (e.g., powerClass, powerClass-v 1610); while the power on each band, nX and nY, cannot exceed the power class reported by its single band (e.g., ue-PowerClass, ue-PowerClass-v1610, ue-PowerClass-v 1700).

If the terminal also reports the power level of each frequency band in the frequency band combination (e.g., ue-PowerClassPerBandPerBC-r 17), the maximum power of each frequency band cannot exceed the power level corresponding to ue-PowerClassPerBandPerBC-r 17.

As can be seen from the above, if the terminal configures a band combination, even in the case of only single band transmission (for example, only 1 component carrier is in an active state) in the actual transmission process, the total power of the terminal is still limited by the power class (for example, powerClass, powerClass-v 1610) reported by the band combination, which may cause power over-restriction on the band.

For example, ue-PowerClass reported in the band X is PC2, powerClass reported in the band combination containing the band X is PC3, and even if only the band X in the band combination is in operation (e.g. other bands are in a deactivated state), the power of the band X is limited to PC3. This affects the uplink coverage of band X and thus affects the communication performance.

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

In some embodiments, a new terminal capability may be introduced, e.g., power class exception (enablepowerclassexception) is allowed, which indicates whether the terminal is allowed in a band combining configuration, and its maximum power depends only on when only a single band is transmitting in the band combining configuration:

(1) IE ue-PowerClass reported by a single frequency band, when only 1 carrier wave transmits on the frequency band;

(2) And the frequency band is combined with IE powerClass reported when a plurality of carriers are transmitted simultaneously on the frequency band.

Example embodiment 1:

A new terminal capability may be introduced, e.g., power class exclusions (enablepowerclassexception) may be allowed, indicating whether the terminal is allowed in a band combination configuration, the maximum power of which depends only on the reported IE ue-PowerClass for a single band when only a single band is transmitted in the band combination configuration.

Here, when there is only a single band with emissions means that the other bands are in a deactivated state; or that only 1 frequency band is scheduled for uplink transmission.

Reporting the terminal capability according to different frequency band combinations, namely reporting granularity is per frequency band combination (per band combination).

For example, as shown in table 2, the terminal reports the following information.

	IE ue-PowerClass	IE powerClass
			nX	PC1.5
nY	PC2
			CA_nX-nY		PC2

TABLE 2

When enablepowerclassexception =0 or absent, the maximum power of e.g. nX or nY on its single band depends on min { IE ue-PowerClass, IE powerClass } or IE ue-PowerClassPerBandPerBC when the terminal is configured for ca_nx-nY carrier aggregation.

When enablepowerclassexception =1, when the terminal is configured for ca_nx-nY carrier aggregation, its maximum power on a single band, for example nX or nY, is in one case dependent only on IE ue-PowerClass, i.e. independent of IE powerClass and IE ue-PowerClassPerBandPerBC.

In another case, if IE ue-PowerClassPerBandPerBC is also reported on the band, the maximum power on the single band depends on IE ue-PowerClassPerBandPerBC. Based on this, in the case that the power configuration of the terminal is shown in table 2, when nX and nY in ca_nx-nY carrier aggregation have only single band transmission, for example, nX transmission, nY deactivation, or nY transmission, nX deactivation, the maximum power supported by the terminal is shown in table 3.

	The nX maximum power depends on	The nY maximum power depends on
			Enablepowerclassexception = 0 or absence of	PC2	PC2
enablepowerclassexception＝1	PC1.5	PC2

TABLE 3 Table 3

Example 2:

the terminal capability is also applicable to frequency band combination of intra-band carrier aggregation in frequency bands. However, in the intra-band combination, only single band transmission means that only a single carrier is transmitted.

For example, single-band IE ue-PowerClass of nX reports PC2, while in the case of intra-band carrier aggregation, corresponding IE powerClass of nXC reports PC3. The maximum power supported by the terminal when nX in the intra-band combination is only single carrier transmitted is shown in table 4.

	The maximum power in the case of nX single carrier depends on
		Enablepowerclassexception = 0 or absence of	PC3
enablepowerclassexception＝1	PC2

TABLE 4 Table 4

Example embodiment 3:

the above terminal capability is also applicable to inter-band combining including intra-band carrier aggregation. As shown in table 5, the terminal reports the following information:

	IE ue-PowerClass	IE powerClass
			nX	PC1.5
nY	PC2
			nYC		PC2
CA_nXA-nYC		PC3

TABLE 5

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

When enablepowerclassexception =0 or does not exist, when the terminal is configured to ca_ nXA-nYC carrier aggregation, there is an in-band continuous carrier aggregation (e.g. nYC) on its single band, and the maximum power of carrier aggregation on its single band depends on that reported when the in-band carrier aggregation is performed, that is, on min { IE powerClass for inter-band, IE powerClass for intra-band }.

When enablepowerclassexception =1, when the terminal is configured to ca_ nXA-nYC carrier aggregation, there is an in-band continuous carrier aggregation (e.g. nYC) on its single band, and the maximum power of carrier aggregation on its single band depends on IE powerClass for intra-band reported during in-band carrier aggregation.

Based on this, in the case where the power configuration of the terminal is shown in table 5, the maximum power supported by the terminal is shown in table 6 when nX and nY in ca_nx-nY carrier aggregation are transmitted only in a single band or there is a transmission on the same band continuous carrier aggregation nYC in ca_ nXA-nYC carrier aggregation.
