Fig. 1 shows a kind of indicative flowchart of power determining method 100.Wherein, this method 100 can be performed by user equipment.As shown in figure 1, this method 100 includes：

S110, determines the Initial Trans of each connection object in connection object set, wherein, the connection object set includes all up channels and/or SRS waiting for transmission；

S120, when the Initial Trans sum of each connection object in the connection object set is more than maximum transmission power, priority ranking based on connection object corresponding informance, perform power reduction operation, to obtain the available launch power of each connection object in the connection object set, wherein, the available launch power sum of each connection object in the connection object set is not more than the maximum transmission power；

S 130, according to each self-corresponding available launch power of each connection object in the connection object set, sends each connection object in the connection object set.

Specifically, the corresponding up channel of the multiple carrier waves of simultaneous transmission and/or SRS (that is, connection object set are being needed）When, user equipment can first calculate the Initial Trans of each connection object in connection object set, after the Initial Trans of each connection object are calculated, the Initial Trans sum of each connection object can be compared by user equipment with maximum transmission power, when the Initial Trans sum of each connection object is less than or equal to maximum transmission power, each connection object in the connection object set can be directly transmitted, when the Initial Trans sum of each connection object is more than maximum transmission power, then need to perform power reduction operation, specifically can be first according to the priority ranking of connection object corresponding informance, and the corresponding informance of each connection object in the connection object set, determine the priority of each connection object, then power reduction operation can be performed according to the priority of each connection object, so as to obtain the available launch power of each connection object in the connection object set, wherein, the available launch power sum of each connection object in the connection object set is not more than the maximum transmission power, after the available launch power of each connection object in obtaining the connection object set, user equipment can be according to each self-corresponding available launch power of each connection object in the connection object set, send each connection object in the connection object set.

It should be noted that, in actual implementation process, due to reasons such as devices, the available launch power sum for each connection object being likely to result in connection object set exceedes the maximum transmission power of user equipment within a small period, but the available launch power sum of each connection object in the connection object set after device is stable is not more than maximum transmission power. In embodiments of the present invention, the Initial Trans of connection object are user equipment before power reduction operation is performed, the transmission power of the connection object of rule calculating is controlled according to related power, if maximum transmission power of the Initial Trans sum not less than user equipment of the connection object waiting for transmission of user equipment, then user equipment needs to launch corresponding connection object according to the Initial Trans, if the Initial Trans sum of the connection object waiting for transmission of user equipment has exceeded the maximum transmission power of user equipment, then user equipment needs to perform power reduction operation, to obtain the available launch power of each connection object.

It should be understood that, in embodiments of the present invention, available launch power for some connection object can be equal to its Initial Trans, its Initial Trans can also be not equal to, for example, for the higher connection object of priority, its available launch power can be equal to Initial Trans, and for the relatively low connection object of priority, its available launch power is then less than Initial Trans.

In embodiments of the present invention, it is necessary to which the corresponding up channel of the multiple carrier waves of simultaneous transmission and/or SRS can be to need in the corresponding up channel of the plurality of carrier wave of same sub-frame transmission and/or SRS;But, due to for needing the corresponding up channel of the multiple carrier waves of simultaneous transmission and/or SRS, although they need simultaneous transmission from the point of view of in time, but the subframe numbers that different up channels and/or SRS are sent may be inconsistent, accordingly, it would be desirable to the object of simultaneous transmission it can be appreciated that regular hour point or needed in the period transmission object.

In embodiments of the present invention, the connection object set, which includes all up channels and/or SRS waiting for transmission, means：In the case where only needing to transmission up channel, the connection object set includes all up channels waiting for transmission；In the case where only needing to transmission SRS, connection object set includes all SRS waiting for transmission;In the case where needing simultaneous transmission up channel and SRS, connection object set includes all up channels waiting for transmission and all SRS.

It should be understood that, in embodiments of the present invention, the priority ranking of connection object corresponding informance can be set in advance, can also be that user equipment is set according to high level configuration dynamic, can also user equipment obtained by other approach, the embodiment of the present invention does any restriction not to this.

In embodiments of the present invention, the priority ranking of connection object corresponding informance can include：At least one of UCI priority ranking of priority ranking carrier wave corresponding with connection object that the priority ranking of the type of connection object, connection object are carried.

In embodiments of the present invention, the priority ranking based on connection object corresponding informance, performs power reduction operation, can include：

According to the priority ranking of connection object corresponding informance, and each in the connection object set The corresponding informance of connection object, determines the priority of each connection object in the connection object set；In all embodiments of the invention, the corresponding informance of connection object can refer to the corresponding type of connection object, for example, the corresponding types of a connection object can be PRACH channels, PUCCH channels, PUSCH channels（Can be specially the PUSCH channels for carrying UCI and the PUSCH channels for not carrying UCI）Or SRS channels；The corresponding informance of connection object can also refer to the information of connection object carrying, and the corresponding informance of such as one connection object can be ascending control information UCI, PUSCH data or SRS;The corresponding informance of connection object can also refer to information of the corresponding carrier wave of connection object etc..

In embodiments of the present invention, the type for each connection object that user equipment can only in the priority ranking of the type of connection object and the connection object set, determines the priority of each connection object in the connection object set；The UCI that each connection object in the UCI that only can also be carried according to connection object priority ranking and the connection object set is carried determines the priority of each connection object in the connection object set；It is of course also possible to only determine the priority of each connection object according to the priority ranking carrier wave corresponding with each connection object in the connection object set of connection object correspondence carrier wave.

In embodiments of the present invention, a kind of priority of each connection object of determination in the priority of the priority ranking carrier wave corresponding with connection object for the UCI that user equipment can also be carried first according to the priority ranking of the type of connection object, connection object, in the case of it there is priority identical, other two kinds or a kind of priority for determining priority identical connection object in the priority ranking of the priority ranking carrier wave corresponding with connection object for the UCI that priority ranking, connection object further according to the type of connection object are carried.

For example, the priority of each connection object in connection object set S can be first determined according to the priority ranking of the type of connection object, if being determined according to the priority ranking of the type of connection object, the priority of multiple connection objects is identical, assuming that the multiple priority identical connection objects determined according to the priority ranking of the type of connection object constitute connection object set S1, each in connection object set S1, which transmits corresponding priority, to be further determined that to the priority ranking of the UCI as carrying further according to transmission, if determining that the priority of multiple connection objects in connection object set S1 is identical to the priority ranking of the UCI as carrying according to transmission, assuming that the multiple connection object composition set S2 of priority identical in connection object set S1, priority ranking further according to connection object correspondence carrier wave further determines that the priority of each connection object in set S2.It is multiple to priority identical in connection object set S1 to pass Defeated object set S2, if the S2 includes the PUCCH1 for carrying HARQ-ACK transmission and the PUCCH2 for carrying HARQ-ACK transmission, it can also be sorted according to the HARQ-ACK transmitted on PUCCH1 and PUCCH2 bit number, the small PUCCH of the big PUCCH of such as HARQ-ACK bit number bit number of the priority higher than HARQ-ACK priority.

For example, user equipment can determine the priority of each connection object in the connection object set according to the type of the priority ranking of the type of connection object, and each connection object in the connection object set；

When there is identical situation in the priority of each connection object in the connection object set that the priority ranking of the type according to connection object and the type of each connection object are determined, according to the priority ranking for passing the UCI that connection object is carried, and the UCI that each connection object in the connection object with equal priority is carried, determine that this has the priority of each connection object in the connection object of equal priority, or

According to the priority ranking of the corresponding carrier wave of connection object, and the corresponding carrier wave of each connection object in connection object with equal priority, determine that this has the priority of each connection object in the connection object of equal priority.

In embodiments of the present invention, the type of connection object can be divided into PRACH, PUCCH, carry UCI PUSCH, do not carry UCI PUSCH and SRS, the priority ranking of the type of the connection object can include following at least one：

When there are PRACH, PRACH highest priority；

When PUCCH and PUSCH simultaneously in the presence of, PUCCH priority is higher than PUSCH priority, or, PUCCH priority be higher than the priority for the PUSCH for not carrying UCI and and carrying UCI PUSCH priority it is identical；

PRACH, PUCCH, PUSCH and SRS simultaneously in the presence of, SRS priority is minimum.Specifically, the priority ranking of the type of the connection object can also be：PRACH priority is higher than PUCCH priority, priority of the PUCCH priority higher than the PUSCH for carrying UCI, the priority for carrying UCI PUSCH is higher than the priority for the PUSCH for not carrying UCI, and the priority that UCI PUSCH is not carried is higher than SRS priority.Or the priority ranking of the type of the connection object can also be：PRACH priority is higher than PUCCH priority, and PUCCH priority is equal to the priority for the PUSCH for carrying UCI, and the priority for carrying UCI PUSCH is high In the priority for the PUSCH for not carrying UCI, the priority that UCI PUSCH is not carried is higher than SRS priority.

In the embodiment of the present invention, if PUCCH priority is identical with the priority for the PUSCH for carrying UCI, it may be such that more important UCI information is preferably protected in application scenes.For example when the UCI carried in the PUSCH for carrying UCI is HARQ-ACK, and PUCCH carry UCI be channel condition information when, PUCCH priority and the PUSCH for carrying UCI priority are first set to identical, to the PUCCH with equal priority and carry UCI PUSCH again and according to the UCI of carrying priority ranking determine priority, it can determine that the priority for the PUSCH for carrying hybrid automatic retransmission request information is higher, so as to carry out higher protection to hybrid automatic retransmission request information, it ensure that the transmission performance of such important information.Connect the scene of (Dual connectivity) for double-strand, or for the scene that UCI can be transmitted on multiple up-link carriers simultaneously, or for allowing the scene of multiple PUCCH simultaneous transmissions over a number of carriers to obtain the beneficial effect.

In embodiments of the present invention, the UCI that connection object is carried can be divided into hybrid automatic retransmission request information, dispatch request and channel condition information, wherein, the priority ranking for the UCI that connection object is carried can include following at least one：

In embodiments of the present invention, the priority ranking for the UCI that connection object is carried can include following at least one：

It should be understood that, in embodiments of the present invention, the UCI carried according to connection object determines the priority of each connection object, the priority of each connection object can be determined according to the priority of the UCI with greatest priority entrained by each connection object, for example, the UCI information that PUCCH channels 1 are carried only includes dispatch request, the UCI information that PUCCH channels 2 are carried only includes channel quality and indicated and pre-coding matrix, so, if the priority according to the content with greatest priority of carrying is ranked up, then the priority of PUCCH channels 1 is higher than the priority of PUCCH channels 2. In embodiments of the present invention, the priority ranking of connection object correspondence carrier wave can include：At least one of priority ranking that priority ranking, the carrier wave priority ranking of high-rise configuration, the priority ranking that the duplex mode based on carrier wave is determined, the priority ranking determined based on the corresponding transfer point of carrier wave and the RRC connections based on carrier wave that index number based on carrier wave is determined are determined.

In embodiments of the present invention, the index of carrier wave can be pre-configured with, and the importance that the carrier index being pre-configured with can be according to carrier wave relative to user equipment is configured.If be ranked up according to the order of importance from high to low, the index of the carrier wave of i.e. high importance is small, then the corresponding priority rule of carrier index is that the order of priority from high to low is the incremental order of carrier index, i.e. the small carrier wave of carrier index has higher priority.Certainly, it can also be ranked up according to the order of importance from low to high, the index of the carrier wave of i.e. high importance is big, then the corresponding priority rule of carrier index is that the order of priority from high to low can be the order that carrier index is successively decreased, i.e. the small carrier wave of carrier index has lower priority.

In embodiments of the present invention, the order of the corresponding priority ranking of carrier wave from high to low can be able to be high level for the high-rise order configured, the i.e. priority ranking by the semi-static order signaled.

In embodiments of the present invention, carrier wave can be corresponding with corresponding transfer point, or say can be corresponding with corresponding base station, for example carrier wave 1 comes from macro base station, carrier wave 2 comes from micro-base station, and now carrier wave priority is transfer point priority, or says as base station priorities.So that user equipment has polymerize two up-link carriers as an example, the corresponding priority of the carrier wave can be corresponding to macro base station（Macro the priority of carrier wave), which is higher than, corresponds to micro-base station（Pico the priority of carrier wave).Such a situation is mainly used in transmitting the wireless heterogeneous networks of user equipment（Radio Resource Control; cylinder claims " RRC ") control information and/or scene during semi-continuous scheduling SPS business; the preferable protection to RRC control information and/or semi-continuous scheduling (Semi Persistent Scheduling, cylinder claims " SPS ") business datum can now be realized.

In embodiments of the present invention, the priority ranking of connection object correspondence carrier wave can include：The priority ranking that duplex mode based on carrier wave is determined, for example, can be that the priority for the carrier wave that duplex mode is FDD (Frequency Division Duplexing, FDD) is less than duplex mode for time division duplex（Time Division Duplexing, TDD) carrier wave priority.

Specifically, the priority ranking based on connection object corresponding informance can include following at least one：It is less than in the priority that duplex mode is the PUCCH transmitted on the carrier wave of FDD in the priority that duplex mode is the PUCCH transmitted on TDD carrier wave, can is now the PUCCH for carrying hybrid automatic retransmission request information in the PUCCH for the upper transmission that duplex mode is the PUCCH that is transmitted on FDD carrier wave and is TDD in duplex mode; It is less than the priority in the PUSCH that duplex mode is the carrying UCI transmitted on TDD carrier wave in the priority that duplex mode is the PUCCH transmitted on FDD carrier wave, the UCI that carrying UCI that now should be in duplex mode to be transmitted on TDD carrier wave PUSCH is carried includes hybrid automatic retransmission request information.

In all embodiments of the invention, when the priority ranking that the priority ranking of connection object correspondence carrier wave determines for the duplex mode based on carrier wave, the scene for TDD and FDD use in conjunction is beneficial to.For example, under this scene, if be the PUCCH that is transmitted on FDD carrier wave in duplex mode and be that the PUCCH transmitted on TDD carrier wave is present in duplex mode simultaneously, and this be the PUCCH transmitted on FDD carrier wave in duplex mode and be somebody's turn to do when it is all to carry the PUCCH of hybrid automatic retransmission request information that duplex mode, which be the PUCCH transmitted on TDD carrier wave, the PUCCH that should be generally transmitted in duplex mode on TDD carrier wave carries the HARQ-ACK of multiple descending sub frames, and may only carry the HARQ-ACK of a descending sub frame in duplex mode for the PUCCH transmitted on FDD carrier wave, so now according to the priority ranking determined based on carrier duplex mode, it is higher than in the priority that duplex mode is the PUCCH transmitted on TDD carrier wave in the priority that duplex mode is the PUCCH transmitted on FDD carrier wave, so as to ensure that in duplex mode be the PUCCH transmitted on TDD carrier wave performance, so that duplex mode need not retransmit for the data of multiple descending sub frames on TDD carrier wave, improve systematic function.

In embodiments of the present invention, the priority ranking of connection object correspondence carrier wave can include：The priority ranking that RRC connections based on carrier wave are determined, the priority for the carrier wave for not supporting RRC connections can be for example higher than for the priority for the carrier wave for supporting RRC connections, or the priority for the carrier wave for not carrying rrc message can be higher than for the priority of the carrier wave of carrying rrc message.In the embodiment of the present invention, user equipment can first determine the priority of connection object according to the priority ranking that should be determined based on RRC connections, if such as carrier wave 1 is the carrier wave of support RRC connections, carrier wave 2 is the carrier wave for not supporting RRC connections, then the priority of carrier wave 1 is higher than the priority of carrier wave 2, i.e. no matter what carrier wave 1 and the corresponding type of the corresponding connection object of carrier wave 2 be, or no matter what the UCI that carrier wave 1 and the corresponding connection object of carrier wave 2 are carried is, the priority of the corresponding connection object of carrier wave 1 is higher than the priority of the corresponding connection object of carrier wave 2.After the priority of connection object is determined according to the priority ranking that should be determined based on RRC connections, when still having priority identical connection object, the priority for the UCI that can be carried further according to the priority and/or connection object of connection object corresponding types further determines that the priority of connection object.

In embodiments of the present invention, according to the priority of each connection object, power reduction operation is performed, can be included： Power reduction operation is performed in the way of the priority orders of each connection object in the connection object set carry out power reduction successively from low to high, until the available launch power sum of each connection object in the connection object set got is less than or equal to the maximum transmission power.

In embodiments of the present invention, this is met in the way of the priority orders of connection object carry out power reduction successively from low to high in the case that the available launch power for being n in priority ranking is not 0, priority ranking is equal to the requirement of Initial Trans for the available launch power of n+1 connection objects, wherein, m is the number of the connection object in the connection object set, m> n >L, and priority ranking is minimum for the priority of 1 connection object.

I.e., based on priority ranking, after the priority for determining each connection object, the transmission power of connection object that can be first minimum to priority carries out power reduction, if the Initial Trans of the minimum connection object of priority can meet reduction when requiring, i.e., when the minimum Initial Trans of priority are more than the difference of the maximum transmission power of the Initial Trans of each connection object and user equipment in connection object set, only the carry out power reduction of the connection object minimum to priority is to obtain the available launch power of the minimum connection object of the priority, the available launch power of other connection objects is equal to Initial Trans；If the Initial Trans of the minimum connection object of priority can not meet reduction and require, then connection object first minimum to priority carries out power reduction, the available launch power for obtaining the minimum connection object of the priority is 0, then, the connection object low to preferential level carries out power reduction, if the Initial Trans of the low connection object of preferential level can meet reduction and require, i.e., when being more than the difference of the maximum transmission power of the Initial Trans of each connection object and user equipment in connection object set by the minimum Initial Trans of priority and the low Initial Trans sum of preferential level, the carry out power reduction of the connection object low to preferential level is to obtain the available launch power that the preferential level is low, other connection objects（Except the low connection object of preferential level and the minimum transmission of priority are to other connection objects in addition to property in connection object set）Available launch power be equal to Initial Trans；If the Initial Trans of the low connection object of preferential level can not meet reduction and require, then the connection object third from the bottom to priority ranking carries out power reduction, by that analogy, until the small sum of the available launch power of each connection object in connection object set is in the maximum transmission power equal to user equipment.

In embodiments of the present invention, when there is multiple connection objects under same priority, constant power reduction can be carried out to multiple connection objects under the same priority.

In embodiments of the present invention, the operation of constant power reduction can be to carry out constant power reduction in proportion to the object for needing to perform power reduction, that is, it is identical value to have carried out the Initial Trans of each connection object of power reduction and the ratio of available launch power.Can also be to needing to carry out power reduction The Initial Trans of connection object subtract the power of identical numerical value.

Assuming that needing the connection object for performing the same priority of power reduction to include connection object A, B and C, the corresponding Initial Trans of connection object A are a, the corresponding Initial Trans of connection object B are b, connection object C transmitting power is c, and it is d to need the power being contracted by.Operation directly can be reduced to the constant power of execution in proportion of all connection objects, you can with according to formula

W (a+b+c)=d obtains coefficient w, it is thus possible to obtain power respectively wa, wb and the wc being contracted by the need for connection object ABC, i.e. available launch power is respectively a-wa, b-wb and c-wc.Can also be to needing the Initial Trans for the connection object for carrying out power reduction to subtract the power of identical numerical value, i.e. can be according to formula 3e=d, obtain e, then connection object A, B, C needs the power respectively d/3 being contracted by, i.e., available launch power is respectively a-d/3, b-d/3 and c-d/3.

It should be understood that the embodiment of the present invention can also carry out power reduction according to other modes to connection object.For example, power reduction can all be carried out to all connection objects, for example, can be according to formula ma+nb+pc=D, wherein, numerical relation between m, n and p can be determined according to the priority of corresponding connection object, so as to being respectively ma, nb and pC o when the transmission power of connection object, B, C

Certainly, in embodiments of the present invention, power reduction can also be carried out otherwise, and the embodiment of the present invention is defined not to this.
