In some embodiments, the first frequency band includes multiple carriers, and the multiple carriers support carrier aggregation within a single frequency band. It can also be understood that the first frequency band refers to a frequency band for carrier aggregation of multiple carriers within a single frequency band.

[0133] In some embodiments, the first frequency band refers to an intra-band CA (intra-band carrier aggregation frequency band) or the first frequency band refers to an intra-band CA (dual connectivity intra-band frequency band).

[0134] In some embodiments, intra-band carrier aggregation includes contiguous intra-band carrier aggregation or non-contiguous intra-band carrier aggregation. Optionally, contiguous intra-band carrier aggregation means that multiple carriers within a frequency band are contiguous, and the contiguous multiple carriers can be aggregated. Optionally, non-contiguous intra-band carrier aggregation means that multiple carriers within a frequency band are non-contiguous, and the non-contiguous multiple carriers can be aggregated.

[0135] In some embodiments, the name of the first information is not limited, and it can be, for example, indication information, reporting information, capability information, etc.

[0136] In some embodiments, the frequency bands included in the first frequency band combination perform carrier aggregation. In some embodiments, the frequency bands included in the first frequency band combination support carrier aggregation. In some embodiments, the frequency bands included in the first frequency band combination have the capability to perform carrier aggregation. In some embodiments, performing carrier aggregation on the frequency bands included in the first frequency band combination may also be referred to as inter-band carrier aggregation.

[0137] In some embodiments, the first frequency band combination includes multiple frequency bands, and the multiple frequency bands support carrier aggregation. In some embodiments, the first information includes frequency band identifiers of the multiple frequency bands included in the first frequency band combination, each frequency band identifier being used to indicate a frequency band. Optionally, the frequency band identifier is a frequency band identifier of frequency band 1, frequency band 2, or another identifier.

[0138] In some embodiments, the first information includes not only the first frequency band combination, but also at least one second frequency band combination, each second frequency band combination including at least two frequency bands. Alternatively, it can also be understood that the first information can also report at least one second frequency band combination. In the embodiment of the present disclosure, the first information can report multiple frequency band combinations, and the reported frequency band combinations are used to indicate the frequency band combinations supported by the terminal. Subsequently, the network device can configure the frequency band for carrier aggregation for the terminal based on the reported frequency band combinations.

[0139] Optionally, the second frequency band combination includes multiple frequency bands, and each frequency band may include a single carrier or multiple carriers. If a single frequency band includes multiple carriers, the multiple carriers support carrier aggregation.

[0140] In some embodiments, each frequency band supported by the terminal has a limited maximum power. The power transmitted on each frequency band cannot exceed the maximum power supported by that frequency band, and the total power transmitted on multiple frequency bands should also not exceed the total maximum power supported by the multiple frequency bands. The total maximum power can also be understood as the maximum total power.

[0141] The following describes how the terminal reports the maximum power.

[0142] In some embodiments, the first information includes a first maximum power, where the first maximum power refers to the maximum power supported by each frequency band included in the first frequency band combination before carrier aggregation is performed. In some embodiments, the number of the first maximum powers is the same as the number of frequency bands included in the first frequency band combination. In some embodiments, there is a one-to-one correspondence between the first maximum powers and the frequency bands included in the first frequency band combination.

[0143] In some embodiments, the first maximum powers corresponding to different frequency bands may be the same or different. In other words, the first maximum powers supported by different frequency bands may be the same or different.

[0144] For example, if the first frequency band combination includes frequency band 1, frequency band 2 and frequency band 3, the first maximum power included in the first information includes three first maximum powers, namely first maximum power 1, first maximum power 2 and first maximum power 3, among which the maximum power of frequency band 1 is first maximum power 1, the maximum power of frequency band 2 is first maximum power 2, and the maximum power of frequency band 3 is first maximum power 3.

[0145] In some embodiments, the maximum power supported by each frequency band of the terminal includes two cases, one of which is the maximum power supported by the frequency band before carrier aggregation is performed, and the other is the maximum power supported by the frequency band after carrier aggregation is performed.

[0146] In some embodiments, the terminal may report the maximum power supported by each frequency band before performing carrier aggregation through the first information. Alternatively, it may be understood that the first maximum power refers to the maximum power supported by an independent frequency band.

[0147] Optionally, the first maximum power is represented by ue-PowerClass (terminal power class). The parameter of the first maximum power is represented by any one of ue-PowerClass (terminal power class), ue-PowerClass-v1610 (terminal power class v1610), or ue-PowerClass-v1700 (terminal power class-v1700).

[0148] In the disclosed embodiments, the power on each frequency band cannot exceed the first maximum power corresponding to that frequency band. In other words, if the frequency band is a separate frequency band, or a frequency band that does not perform carrier aggregation, the power on that frequency band cannot exceed the first maximum power corresponding to that frequency band.

[0149] In some embodiments, the first information includes a second maximum power, where the second maximum power refers to the total maximum power supported by all frequency bands included in the first frequency band combination after carrier aggregation. In some embodiments, each frequency band combination corresponds to a second maximum power. In some embodiments, there is a one-to-one correspondence between frequency band combinations and second maximum powers. In some embodiments, the number of frequency band combinations is the same as the number of second maximum powers.

[0150] In some embodiments, each frequency band supported by the terminal has a corresponding maximum power, and for multiple frequency bands performing carrier aggregation, the total maximum power of the multiple frequency bands is also limited.

[0151] It should be noted that the total maximum power supported by all frequency bands included in the first frequency band combination after carrier aggregation in the embodiments of the present disclosure is not the sum of the maximum powers supported by all frequency bands after carrier aggregation. Alternatively, it can be understood that the second maximum power is a self-defined total maximum power supported by all frequency bands included in the first frequency band combination after carrier aggregation.

[0152] For example, the first frequency band combination includes three frequency bands, namely frequency band 1, frequency band 2, and frequency band 3. The maximum power corresponding to frequency band 1 is maximum power 1, the maximum power corresponding to frequency band 2 is maximum power 2, and the maximum power corresponding to frequency band 3 is maximum power 3. The second maximum power corresponding to the first frequency band combination is maximum power 4, where maximum power 4 is different from the sum of maximum power 1, maximum power 2, and maximum power 3. In other words, maximum power 4 is not determined by the sum of maximum power 1, maximum power 2, and maximum power 3.

[0153] Optionally, the second maximum power is represented by powerClass (power class). The parameter of the second maximum power is represented by either PowerClass (power class) or PowerClass-v1610 (power class-v1610).

[0154] In the embodiment of the present disclosure, the sum of the power on each frequency band included in the first frequency band combination cannot exceed the second maximum power corresponding to the first frequency band combination.

[0155] In some embodiments, the maximum power supported by the first frequency band is the same as the second maximum power, and the maximum power supported by the first frequency band is the second maximum power. Alternatively, it can also be understood that, when it is determined that the maximum power supported by the first frequency band is the same as the second maximum power, the maximum power supported by the first frequency band is determined to be the second maximum power. Alternatively, it can also be understood that if the maximum power supported by the first frequency band is the same as the second maximum power, the maximum power supported by the first frequency band is determined to be the second maximum power. In the embodiment of the present disclosure, the maximum power supported by the first frequency band reuses the second maximum power, that is, the second maximum power extension is applied to the maximum power of the first frequency band.

[0156] In some embodiments, the maximum power supported by the first frequency band refers to the maximum power after the first frequency band performs intra-band carrier aggregation and performs carrier aggregation with other frequency bands in the first frequency band combination. Alternatively, it can also be understood that the maximum power supported by the first frequency band refers to the maximum power supported after the first frequency band performs intra-band carrier aggregation and inter-band carrier aggregation. It should be noted that the maximum power supported by the first frequency band involved in the embodiments of the present disclosure can be replaced by the maximum power after the first frequency band performs intra-band carrier aggregation and performs carrier aggregation with other frequency bands in the first frequency band combination, and the embodiments of the present disclosure are not limited to this.

[0157] In some embodiments, the second maximum power is a configured maximum power, and the first frequency band is an in-band frequency band. Therefore, the maximum power supported by the first frequency band is determined as the second maximum power to reduce resource overhead.

[0158] In some embodiments, when the maximum power supported by the first frequency band is the same as the second maximum power, the maximum power supported by the first frequency band is determined to be the second maximum power.

[0159] In the embodiment of the present disclosure, the power in the first frequency band cannot be higher than the second maximum power, which can also be understood as the total power in the first frequency band cannot be higher than the second maximum power.

[0160] In some embodiments, the maximum power supported by the first frequency band is different from the second maximum power, and the maximum power supported by the first frequency band is the minimum of the third maximum power corresponding to the first frequency band and the second maximum power, where the third maximum power refers to the maximum power supported by the first frequency band before carrier aggregation is performed. Alternatively, it can be understood that when the maximum power supported by the first frequency band is different from the second maximum power, the maximum power supported by the first frequency band is determined to be the minimum of the third maximum power corresponding to the first frequency band and the second maximum power.

[0161] In some embodiments, the first frequency band before carrier aggregation is performed refers to after intra-band carrier aggregation is performed on the first frequency band and before carrier aggregation is performed on the first frequency band with other frequency bands in the first frequency band combination. Alternatively, it can be understood that the first frequency band before carrier aggregation is performed refers to after intra-band carrier aggregation is performed on the first frequency band and before inter-band carrier aggregation is performed on the first frequency band.

[0162] In an embodiment of the present disclosure, if the maximum power supported by the first frequency band is different from the second maximum power, the maximum power supported by the first frequency band cannot be determined as the second maximum power. At this time, the terminal also needs to report the maximum power supported by the first frequency band separately. Therefore, the maximum power supported by the first frequency band is determined as the minimum value of the third maximum power corresponding to the first frequency band and the second maximum power.

[0163] It should be noted that, in the above embodiment, if the maximum power supported by the first frequency band is different from the second maximum power, it is indicated that the maximum power supported by the first frequency band is reported. If the maximum power supported by the first frequency band is the same as the second maximum power, there is no need to report the maximum power supported by the first frequency band, but the second maximum power is used as the maximum power supported by the first frequency band.

[0164] In some embodiments, separately reporting the maximum power supported by the first frequency band can also be understood as determining the maximum power supported by the first frequency band by using the third maximum power and the second maximum power.

[0165] For example, if the first frequency band combination consists of nX-nYC, where nYc means that the frequency band of nY is the first frequency band, that is, the frequency band is an intra-band carrier aggregation frequency band, so its total power cannot exceed the second maximum power. When the second maximum power is greater than the first maximum power of nYC, the maximum power supportable on nYC is determined by the third maximum power of nYC.

[0166] It should be noted that the disclosed embodiment is described based on the first maximum power to facilitate determination of the maximum power supported by the first frequency band. In another embodiment, the first information may also directly indicate the maximum power of the first frequency band. In some embodiments, the first information is dedicated information specifically for reporting the maximum power of the first frequency band.

[0167] In some embodiments, the first information is sent when the maximum power of the first frequency band is different from the first maximum power corresponding to the first frequency band. In some embodiments, the maximum power of each carrier on the first frequency band is the minimum of the first maximum power and the maximum power of the first frequency band.

[0168] In some embodiments, the first information includes a fourth maximum power, where the fourth maximum power refers to the maximum power supported by each frequency band included in the first frequency band combination after carrier aggregation is performed. In the embodiments of the present disclosure, each frequency band included in the first frequency band combination will perform carrier aggregation, and the maximum power supported by the frequency bands performing carrier aggregation before and after carrier aggregation may be different. Therefore, the terminal can report the fourth maximum power, that is, the maximum power supported by each frequency band in the first frequency band combination after carrier aggregation is performed.

[0169] In some embodiments, the fourth maximum power is represented by ue-PowerClassPerBandPerBC (terminal power class per frequency band per combination). The parameter of the fourth maximum power is represented by ue-PowerClassPerBandPerBC-r17 (terminal power class per frequency band per combination - r17).

[0170] In the embodiment of the present disclosure, the power on each frequency band included in the first frequency band combination cannot exceed the corresponding fourth maximum power.

[0171] In some embodiments, the number of the fourth maximum powers is the same as the number of frequency bands included in the first frequency band combination. In some embodiments, the fourth maximum powers are in a one-to-one correspondence with the frequency bands included in the first frequency band combination.

[0172] In some embodiments, if the maximum power supported by the first frequency band is different from the first value, it is determined that the first information includes a fourth maximum power, where the first value refers to the minimum value of the first maximum power and the second maximum power corresponding to the first frequency band, the first maximum power refers to the maximum power supported by the first frequency band before carrier aggregation is performed, and the second maximum power refers to the total maximum power supported by all frequency bands included in the first frequency band combination after carrier aggregation is performed. Alternatively, it can be understood that, if the maximum power supported by the first frequency band is different from the first value, it is determined that the first information needs to include a fourth maximum power, and the fourth maximum power is used to indicate the maximum power supported by each frequency band.

[0173] In an embodiment of the present disclosure, if the minimum value of the first maximum power and the second maximum power corresponding to the first frequency band is different from the maximum power supported by the first frequency band, the maximum power supported by the first frequency band cannot be directly determined by multiplexing at this time. Therefore, the maximum power supported by the first frequency band needs to be reported separately at this time. Therefore, the total maximum power supported by all frequency bands included in the first frequency band combination after carrier aggregation is performed is reported.

[0174] For example, if the first maximum power corresponding to the first frequency band is maximum power 1, the second maximum power is maximum power 2, and the maximum power 1 is less than the maximum power 2, then it means that the minimum value is maximum power 1, and the maximum power supported by the first frequency band is maximum power 3, that is, maximum power 1 and maximum power 3 are different, so the fourth maximum power needs to be carried in the first information, and the maximum power supported by each frequency band is indicated by the fourth maximum power.

[0175] In some embodiments, the fourth maximum power is the maximum power supported by the first frequency band after carrier aggregation. That is, if the maximum power supported by the first frequency band is different from the first value, the first information includes the maximum power supported by the first frequency band after carrier aggregation. For other frequency bands in the first frequency band combination, the maximum power supported before carrier aggregation can be reused. In some embodiments, the other frequency bands in the first frequency band combination are all single-carrier frequency bands.

[0176] In some embodiments, if the maximum power supported by the first frequency band is the same as the first value, it is determined that the first information does not include the fourth maximum power, the first value refers to the minimum value of the third maximum power and the second maximum power corresponding to the first frequency band, the maximum power supported by the first frequency band is the first value, and the maximum power supported by other frequency bands in the first frequency band combination except the first frequency band is the maximum power supported by the other frequency bands before carrier aggregation is performed.

[0177] In an embodiment of the present disclosure, if the minimum value of the first maximum power and the second maximum power corresponding to the first frequency band is the same as the maximum power supported by the first frequency band, it means that the first frequency band can reuse the existing maximum power at this time. Therefore, the maximum power supported by the first frequency band reuses the minimum value of the third maximum power and the second maximum power, and the other frequency bands in the first frequency band combination reuse the maximum power supported by other frequency bands before performing carrier aggregation.

[0178] In some embodiments, "before performing carrier aggregation on other frequency bands" refers to before performing carrier aggregation between other frequency bands, or can also be understood as before performing carrier aggregation on other frequency bands with the first frequency band, or can also be understood as before performing inter-band carrier aggregation on other frequency bands. In some embodiments, the other frequency bands in the first frequency band combination refer to single-carrier frequency bands. Alternatively, the other frequency bands can also be understood as frequency bands that do not perform intra-band carrier aggregation.

[0179] In some embodiments, the maximum power supported by the first frequency band is the fourth maximum power corresponding to the first frequency band included in the first information. Alternatively, it can be understood that, if the first information includes the fourth maximum power, the maximum power supported by the first frequency band is the fourth maximum power corresponding to the first frequency band included in the first information. Alternatively, it can be understood that, if the first information includes the fourth maximum power, the maximum power supported by the first frequency band is based on the fourth maximum power corresponding to the first frequency band included in the first information.

[0180] For example, if the first information includes frequency band 1, frequency band 2 and frequency band 3, the fourth maximum power corresponding to frequency band 1 is the fourth maximum power 1, the fourth maximum power corresponding to frequency band 2 is the fourth maximum power 2, the fourth maximum power corresponding to frequency band 3 is the fourth maximum power 3, and frequency band 1 is the first frequency band, that is, frequency band 1 is the frequency band for performing in-band carrier aggregation, so the maximum power supported by the first frequency band is the fourth maximum power 1 corresponding to frequency band 1.

[0181] It should be noted that if the first information reported by the terminal includes a first maximum power, a second maximum power, and a fourth maximum power at the same time, the maximum power of the first frequency band may be determined by using the minimum of the first maximum power and the second maximum power corresponding to the first frequency band, or by using the fourth maximum power, which is not limited in the present embodiment. Alternatively, if the first information reported by the terminal includes a first maximum power, a second maximum power, and a fourth maximum power at the same time, the fourth maximum power shall be used for determination.

[0182] The following describes the embodiments of the present disclosure by way of examples.

[0183] In some embodiments, ue-PowerClass is the maximum power of a single frequency band before carrier aggregation, powerClass is the total maximum power after carrier aggregation, and ue-PowerClassPerBandPerBC is the maximum power of each frequency band after carrier aggregation. See Table 1. If it is only the frequency band for carrier aggregation, the total power does not exist, and the maximum power of a single frequency band is ue-PowerClass; if intra-band CA exists, the total power is powerClass, and the intra-band power is Min(IE powerClass, IE ue-PowerClass); or, if inter-band CA exists, the total power is powerClass, and the intra-band power is Min(IE powerClass, IE ue-PowerClass) or ue-PowerClassPerBandPerBC; if inter-band including intra-band CA exists, the total power is powerClass, and the intra-band power is Min(IE powerClass, IE ue-PowerClass) or ue-PowerClassPerBandPerBC.

[0184] Table 1

[0185] The following describes how to determine the power using frequency bands n1 and n41 as examples. Table 2 shows the maximum power of frequency bands in various situations.

[0186] Table 2

[0187] The power corresponding to PC3 is 23dBm, the power corresponding to PC2 is 26dBm, and the power corresponding to PC1.5 is 29dBm. For n1 alone, the reported power is ue-PowerClass = PC3, which determines the maximum power supported by n1 to be 23dBm. For n41 alone, the reported power is ue-PowerClass = PC1.5, which determines the maximum power supported by n41 to be 29dBm. For CA_n1C (in the case of intra-band carrier aggregation of multiple carriers within the n1 band), no power is reported, so the total maximum power is 23dBm, and the maximum power supported by n1 is 23dBm. For CA_n41C (in the case of intra-band carrier aggregation of multiple carriers within the n41 band), the reported IE powerClass = PC2 (total maximum power) determines the total maximum power to be 26dBm, and the maximum power supported by n1 is 26dBm. For CA_n1A-n41A (the case of single n1 and single n41 carrier aggregation), if IE powerClass = PC2 is reported and ue-PowerClassPerBandPerBC is not reported, the total maximum power is determined to be 26dBm, the maximum power supported by n1 is 23dBm, and the maximum power supported by n41 is 26dBm; if IE powerClass = PC2 is reported and n41 reports PC3 through ue-PowerClassPerBandPerBC, the total maximum power is determined to be 26dBm, the maximum power supported by n1 is 23dBm, and the maximum power supported by n41 is 23dBm (or, it can also be understood that if IE powerClass = PC2 and n41 is reported through ue-PowerClassPerBandPerBC, the maximum power of n41 is based on ue-PowerClassPerBandPerBC.For CA_n1A-n41C (where only n1 and n41 perform intra-band carrier aggregation, and n1 and n41 perform carrier aggregation), if IE powerClass = PC1.5 is reported, ue-PowerClassPerBandPerBC is not reported, and IE power class for n41C for n41 performing intra-band carrier aggregation is not reported, the total maximum power is determined to be 29 dBm, the maximum power supported by n1 is 23 dBm, and the maximum power supported by n41 is 29 dBm (which can be understood as, if IE powerClass = PC2 is reported, IE power class for n41C = PC2 and ue-PowerClassPerBandPerBC is not reported, then n1 is based on ue-PowerClass = PC3, and the maximum power of n41 is based on IE powerClass = PC1.5); if IE powerClass = PC2 is reported, ue-PowerClassPerBandPerBC is not reported, and IE power class for n41 performing intra-band carrier aggregation is reported If n41C=PC2, the total maximum power is determined to be 26dBm, the maximum power supported by n1 is 23dBm, and the maximum power supported by n41 is 26dBm (it can be understood that if IE powerClass=PC2 and IE power class for n41C=PC2 are reported, and ue-PowerClassPerBandPerBC is not reported, then n1 is based on ue-PowerClass=PC3, and the maximum power of n41 is based on IE powerClass=PC2); if IE powerClass=PC2 is reported, n41 reports PC3 through ue-PowerClassPerBandPerBC, and the IE power class for n41C for n41 to perform intra-band carrier aggregation is not reported, then the total maximum power is determined to be 26dBm, the maximum power supported by n1 is 23dBm, and the maximum power supported by n41 is 23dBm (it can be understood that if IE If powerClass = PC2 and n41 is reported using ue-PowerClassPerBandPerBC, the maximum power of n1 is based on ue-PowerClass = PC3, and the maximum power of n41 is based on ue-PowerClassPerBandPerBC.

[0259] FIG6 is a flow chart of an indication method according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to an indication method, and the method includes:

[0260] In step S6101, the terminal or network device applies per band combination power reporting to the intra-band CA / DC case, and extends the per band per band combination power reporting to inter-band including intra-band CA / DC.

[0261] In some embodiments, for per-band combination reporting of intra-band CA, if its power class is different from UE power class, IE powerClass must be reported, otherwise it may not be reported.

[0262] In some embodiments, for inter-band including intra-band CA, when the power class on the component band is different from the Min (IE powerClass, IE ue-PowerClass), it must be reported, otherwise it may not be reported. LR receiver types include OOK-based receivers and OFDM-based receivers.

[0263] In some embodiments, the per-band combination power reporting in existing standards is extended to apply to intra-band CA / DC cases, or the per-band per-band combination power reporting is extended to apply to inter-band including intra-band CA / DC, and the following rules are defined: (The intra-band CA / DC may include both intra-band continuous CA / DC and intra-band discontinuous CA / DC)

[0264] In some embodiments, for any combination (intra-band CA, inter-band CA, inter-band including intra-band CA), the total power level cannot exceed the power level reported for that band combination. For intra-band CA, if its power level is lower than the power level reported per band combination, the per band combination power level on the intra-band CA must be reported.

[0265] In some embodiments, the power class of each band in a band combination is determined by Min(IE powerClass, IE ue-PowerClass). For example, when reporting CA_nX-nYC, the total power cannot exceed the power class reported for that band combination. When the per-band combination power class is greater than the per-band combination power reported for nYC (i.e., intra-band CA alone), the latter determines the maximum power class supported on nYC.

[0266] In some embodiments, when the terminal also reports per-band per-band combination power classes (e.g., ue-PowerClassPerBandPerBC-r17), the maximum power of each band cannot exceed the power class corresponding to ue-PowerClassPerBandPerBC-r17. Furthermore, the per-band per-band combination reporting rules stipulate that if the power class of a component band differs from the Min (IE powerClass, IE ue-PowerClass), it must be reported. Otherwise, it need not be reported.

[0267] In another embodiment, dedicated reporting signaling for intra-band CA / DC can be introduced, such as intra-bandpowerClass. This signaling is required to be reported when the intra-band CA / DC power differs from ue-PowerClass; otherwise, it is not reported. The total power of intra-band CA / DC depends on intra-bandpowerClass, and the power on each carrier is determined by (Min(IE intra-bandpowerClass, IE ue-PowerClass)).

[0268] In another embodiment, in the inter-band including intra-band CA / DC case, the power of the band including CA / DC depends on min(IE powerClass, IE intra-bandPowerClass).

[0269] In another embodiment, if the terminal also reports per-band per-band combination power classes (e.g., ue-PowerClassPerBandPerBC-r17), the maximum power of each band cannot exceed the power class corresponding to ue-PowerClassPerBandPerBC-r17. Furthermore, the per-band per-band combination reporting rule requires that if the power class of a component band differs from the Min (IE powerClass, IE ue-PowerClass), it must be reported. Otherwise, it need not be reported.
