For example, if the first band combination includes band 1, band 2 and band 3, the first maximum power included in the first information includes 3, which are respectively a first maximum power 1, a first maximum power 2 and a first maximum power 3, where the maximum power of band 1 is a first maximum power 1, the maximum power of band 2 is a first maximum power 2, and the maximum power of band 3 is a first maximum power 3.

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 one of which is the maximum power supported by the frequency band after carrier aggregation is performed.

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 is also understood that the first maximum power refers to the maximum power supported by the separate frequency band.

Alternatively, the first maximum power is expressed in terms of ue-PowerClass. The parameter of the first maximum power is represented by any one of ue-PowerClass (terminal power class), ue-PowerClass-v1610 (terminal power equal v 1610) or ue-PowerClass-v1700 (terminal power class-v 1700).

In the embodiment of the disclosure, the power on each frequency band cannot exceed the first maximum power corresponding to the frequency band. That is, if the frequency band is a separate frequency band, or a frequency band in which carrier aggregation is not performed, the power in the frequency band cannot exceed the first maximum power corresponding to the frequency band.

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

In some embodiments, each frequency band supported by the terminal corresponds to a maximum power, and for a plurality of frequency bands for which carrier aggregation is performed, there is also a limit to the total maximum power of the plurality of frequency bands.

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

For example, the first band combination includes 3 bands, namely, band 1, band 2 and band 3, wherein the maximum power corresponding to band 1 is maximum power 1, the maximum power corresponding to band 2 is maximum power 2, the maximum power corresponding to band 3 is maximum power 3, and the second maximum power corresponding to the first band combination is maximum power 4, wherein the maximum power 4 is different from the sum of the maximum power 1, the maximum power 2 and the maximum power 3. That is, the maximum power 4 is not determined by the sum of the maximum power 1, the maximum power 2, and the maximum power 3.

Alternatively, the second maximum power is represented by powerClass. The parameter of the second maximum power is represented by either PowerClass or PowerClass-v1610 (power class-v 1610).

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

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 may be understood that, in the case where 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 may 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 as the second maximum power. In the embodiment of the present disclosure, the maximum power supported by the first frequency band multiplexes the second maximum power, that is, the second maximum power extension is applied to the maximum power of the first frequency band.

In some embodiments, the maximum power supported by the first frequency band refers to the maximum power of the first frequency band after performing in-band carrier aggregation and carrier aggregation with other frequency bands in the first frequency band combination. Alternatively, it may be understood that the maximum power supported by the first frequency band refers to the maximum power supported by the first frequency band after the in-band carrier aggregation and the inter-band carrier aggregation are performed. It should be noted that, in the embodiments of the present disclosure, the maximum power supported by the first frequency band may be the maximum power obtained by performing in-band carrier aggregation by using the first frequency band and performing carrier aggregation with other frequency bands in the first frequency band combination, which is not limited in the embodiments of the present disclosure.

In some embodiments, the second maximum power is configured maximum power, and the first band is an in-band, so that the maximum power supported by the first band is determined as the second maximum power, thereby reducing resource overhead.

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.

In the embodiment of the present disclosure, the power in the first frequency band cannot be higher than the second maximum power, and it is also understood that the total power in the first frequency band cannot be higher than the second maximum power.

In some embodiments, 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 a minimum value of a third maximum power and a second maximum power corresponding to the first frequency band, and the third maximum power refers to the maximum power supported by the first frequency band before carrier aggregation is performed. Alternatively, it may 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 value between the third maximum power and the second maximum power corresponding to the first frequency band.

In some embodiments, the first frequency band before carrier aggregation is performed refers to after the first frequency band performs in-band carrier aggregation, and before the first frequency band performs carrier aggregation with other frequency bands in the first frequency band combination. Alternatively, it may be understood that the first frequency band before carrier aggregation is performed means that the first frequency band performs in-band carrier aggregation, and the first frequency band does not perform inter-band carrier aggregation.

In the 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, and the terminal also needs to report the maximum power supported by the first frequency band separately at this time, so that the maximum power supported by the first frequency band is determined as the minimum value of the third maximum power and the second maximum power corresponding to the first frequency band.

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, reporting the maximum power supported by the first frequency band is described, and if the maximum power supported by the first frequency band is the same as the second maximum power, reporting the maximum power supported by the first frequency band is not required, but the second maximum power is used as the maximum power supported by the first frequency band.

In some embodiments, reporting the maximum power supported by the first frequency band separately may also be understood as determining the maximum power supported by the first frequency band by the third maximum power and the second maximum power.

For example, if the first band combination is made up of nX-nYC, where nYc means that the band of nY is the first band, that is, the band is the intra-band carrier aggregated band, and therefore the total power cannot exceed the second maximum power, when the second maximum power is greater than the first maximum power of nYC, the maximum supportable at nYC is determined by the third maximum power of nYC.

It should be noted that, the embodiments of the present disclosure are described with reference to the first maximum power so as to determine 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, and the maximum power of the first frequency band is reported exclusively.

In some embodiments, the first information is transmitted 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.

In some embodiments, the first information includes a fourth maximum power, and the fourth maximum power refers to a maximum power supported by each frequency band included in the first frequency band combination after carrier aggregation is performed. In the embodiment of the present disclosure, each frequency band included in the first frequency band combination may perform carrier aggregation, and the maximum power supported by the frequency band performing carrier aggregation may be different between before and after performing carrier aggregation, so that the terminal may report the fourth maximum power, that is, the maximum power supported by each frequency band in the first frequency band combination after performing carrier aggregation.

In some embodiments, the fourth maximum power is expressed in terms of ue-PowerClassPerBandPerBC (terminal power class per band per combination). The fourth maximum power parameter is expressed by ue-powerclassperband perbc-r17 (terminal power class per band per combination-r 17).

In an 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.

In some embodiments, the fourth maximum power is the same number of frequency bands included within the first frequency band combination. In some embodiments, the fourth maximum power is in a one-to-one correspondence with the frequency bands included in the first frequency band combination.

In some embodiments, if the maximum power supported by the first frequency band is different from the first value, determining that the first information includes the fourth maximum power, where the first value is a minimum value between the first maximum power and the second maximum power corresponding to the first frequency band, the first maximum power is the maximum power supported by the first frequency band before carrier aggregation is performed, and the second maximum power is the total maximum power supported by all frequency bands included in the first frequency band combination after carrier aggregation is performed. Alternatively, it may be understood that, in the case where the maximum power supported by the first frequency band is different from the first value, it is determined that the fourth maximum power needs to be included in the first information, and the maximum power supported by each frequency band is indicated by the fourth maximum power.

In the 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 in a multiplexing manner at this time, so that the maximum power supported by the first frequency band needs to be reported separately at this time, and therefore, the total maximum power supported by all frequency bands included in the first frequency band combination after carrier aggregation is performed is reported.

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 maximum power 1 is smaller than maximum power 2, 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 that 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.

In some embodiments, the fourth maximum power is a maximum power supported by the first frequency band after carrier aggregation is performed. 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 is performed. And for other frequency bands in the first frequency band combination, multiplexing the maximum power supported before carrier aggregation. In some embodiments, the other frequency bands in the first frequency band combination are all single carrier frequency bands.

In some embodiments, if the maximum power supported by the first frequency band is the same as a first value, it is determined that the first information does not include the fourth maximum power, where the first value is a minimum value of a third maximum power and a 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 powers supported by other frequency bands except for the first frequency band in the first frequency band combination are the maximum powers supported by the other frequency bands before carrier aggregation is performed.

In the 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 is indicated that the first frequency band can multiplex the existing maximum power at this time, so that the maximum power supported by the first frequency band multiplexes the minimum value of the third maximum power and the second maximum power, and other frequency bands in the first frequency band combination multiplex the maximum powers supported by other frequency bands before carrier aggregation is performed.

In some embodiments, before carrier aggregation is performed on other frequency bands, or before carrier aggregation is performed on other frequency bands and the first frequency band, or before inter-band carrier aggregation is performed on other frequency bands. In some embodiments, the other frequency bands in the first frequency band combination refer to single carrier frequency bands. Alternatively, other frequency bands may be understood as frequency bands in which no in-band carrier aggregation is performed.

In some embodiments, the maximum power supported by the first frequency band is a fourth maximum power corresponding to the first frequency band included in the first information. Alternatively, it may be understood that, in the case where 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 may 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.

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

It should be noted that, if the first maximum power, the second maximum power, and the fourth maximum power exist in the first information reported by the terminal at the same time, the maximum power of the first frequency band may be determined by using a minimum value of the first maximum power and the second maximum power corresponding to the first frequency band, or may be determined by using the fourth maximum power, which is not limited in the embodiment of the present disclosure. Or if the first maximum power, the second maximum power and the fourth maximum power exist in the first information reported by the terminal at the same time, determining by adopting the fourth maximum power.

Embodiments of the present disclosure are described below by way of example.

In some embodiments, ue-PowerClass is the maximum power of a single band before carrier aggregation, powerClass is the total maximum power after carrier aggregation, ue-PowerClass per band per bc is the maximum power of each band after carrier aggregation, see table 1, if only the band of carrier aggregation, the total power is not present, and the maximum power of a single band is ue-PowerClass; if Intra-band CA is present, the total power is powerClass and the Intra-band power is Min (IE powerClass, IEue-PowerClass); alternatively, if Inter-band CA is present, the total power is powerClass, the Intra-band power is Min (IE powerClass, IE ue-powerClass) or ue-PowerClassPerBandPerBC; if Inter-band including Intra-band CA is present, the total power is PowerClass and the Intra-band power is Min (IE PowerClass, IE ue-PowerClass) or ue-PowerClassPerBandPerBC.

For the case where n41 alone exists, the reported power is ue-powerclass=pc 1.5, and then the maximum power supported by n41 is determined to be 29dBm. For ca_n1c (where multiple carriers in the n1 band are aggregated in band), if no report is given, the total maximum power is determined to be 23dBm, and the maximum power supported by n1 is determined to be 23dBm. For ca_n41c (where multiple carriers within the n41 band are aggregated in-band), if IE powerclass=pcs 2 (total maximum power) is reported, then the total maximum power is determined to be 26dBm, and the maximum power supported by n1 is determined to be 26dBm. For ca_n1a-n41A (case where single n1 and single n41 are carrier aggregated), if IE powerclass=pc2 is reported, ue-powerClass per band per bc 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 the reporting IE powerclass=pc2, n41 is PC3 reported by ue-powerClass per bandperbc, then the total maximum power is determined to be 26dBm, the maximum power supported by n1 is determined to be 23dBm, the maximum power supported by n41 is determined to be 23dBm (alternatively, it can be understood that if IE powerclass=pc2 and n41 is reported by ue-powerClass per bandperbc, then the maximum power of n41 is determined to be 29dBm, the maximum power supported by n1 bc is determined to be 29dBm, and the maximum power supported by n1A-n41C (where single n1 and n41 perform carrier aggregation), if the reporting IE powerclass=pc 1.5, and the reporting IE powerClass per pert 41 performs in-band carrier aggregation, then the maximum power supported by n41 is determined to be 29dBm, the maximum power supported by n1 bc is determined to be 29dBm, and the maximum power supported by n41 is determined to be 2 = PC1.5, and the maximum power supported by n41 is determined to be 2 = PC 4; if IE powerclass=pc2 is reported, ue-PowerClassPerBandPerBC is not reported, and IE power class for n41 c=pc2 is reported where n41 performs in-band carrier aggregation, then the total maximum power is determined to be 26dBm, the maximum power supported by n1 is 23dBm, the maximum power supported by n41 is 26dBm (it can be understood that IE powerclass=pc2 and IE power class for n 3543c=pc2 are reported, ue-PowerClassPerBandPerBC is not reported, then n1 is subject to ue-powerclass=pc3, the maximum power of n41 is subject to IE powerclass=pc2), if IE powerclass=pc2 is reported, n41 is subject to PC3 by ue-powerssperdbbc, then IE power class for n C is not reported where n41 performs in-band carrier aggregation, 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 is understood that if IE powerclass=pc 2 and n41 is reported by ue-powerClass per bandper bc, the maximum power of n1 is based on ue-powerclass=pc 3 and the maximum power of n41 is based on ue-powerClass per bandper bc).

Fig. 6 is a flow chart illustrating an indication method according to an embodiment of the present disclosure, and as shown in fig. 6, the embodiment of the present disclosure relates to an indication method, where the method includes:

in step S6101, the terminal or the network device extends per band combination power reporting to be applicable to intra-band CA/DC case, per band per band combination power reporting to be applicable to inter-band including intra-band CA/DC.

In some embodiments, for the per-band combination reporting of intra-band CA, if its power level is not the same as the UE power class, the IE powerClass must be reported, otherwise it may not be reported.

In some embodiments, for inter-band including intra-band CA, when the power level on the constituent band is different from Min (IE powerClass, IE ue-powerClass), then reporting is necessary, otherwise no reporting may be necessary. LR receiver types include OOK-based and OFDM-based receivers.

In some embodiments, the power reporting of per band combination in the existing standard is extended to fit within the intra-band CA/DC case and or Per band per band combination power reporting is extended to fit within-band including intra-band CA/DC and the following rules are defined: (the intra-band CA/DC may include continuous CA/DC in the same band, and discontinuous CA/DC in the same band)

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

In some embodiments, the power level on a single band for its composition on a band combination is determined by Min (IE powerClass, IE ue-powerClass). For example: the total power of ca_nx-nYC, when reported, cannot exceed the power level reported by the band combination, and the maximum supportable power level at nYC is determined by the latter when the per band combination power level is greater than nYC, i.e., per band combination reported by intra-band CA alone.

In some embodiments, when the terminal also reports per band per band combination power levels (e.g., ue-PowerClassPerBandPerBC-r 17), the maximum power of each band cannot exceed the corresponding power level of ue-PowerClassPerBandPerBC-r 17. And per band per band combination reports rules that must be reported when the power level on the constituent band is different from Min (IE powerClass, IE ue-powerClass).
