Description

Power determination method, user equipment and base station

Technical Field

The present invention relates to the field of communications, and more particularly, to a power determination method, a user equipment, and a base station.

Background

The Advanced long term evolution (Long Term Evolution-Advanced, abbreviated as "LTE-a") system is a further evolution and enhancement system of the third generation partnership project (3 rd Generation Partnership Project, abbreviated as "3 GPP") long term evolution (Long Term Evolution, abbreviated as "LTE") system. In the LTE-a system, in order to meet the peak data rate requirement of the international telecommunications union for the fourth generation communication technology, a carrier aggregation (Carrier Aggregation, abbreviated as "CA") technology, also referred to as a spectrum aggregation (Spectrum Aggregation) technology or a bandwidth extension (Bandwidth Extension) technology, is introduced. In carrier aggregation, the spectrums of two or more component carriers (Component Carrier) are aggregated together to obtain a wider transmission bandwidth, and the spectrums of each component carrier can be adjacent continuous spectrums, non-adjacent spectrums in the same frequency band or discontinuous spectrums in different frequency bands; the LTE Rel-8/9 User Equipment (UE) can only access one of the component carriers for data transmission and reception, and the LTE-A User Equipment can access a plurality of component carriers for data transmission and reception according to the capability and service requirements.

To support dynamic scheduling and downlink mimo (Multiple Input Multiple Output, abbreviated

The terminal needs to feed back various uplink control information (Uplink Control Information, abbreviated as "UCI") including channel state information (Channel State Information, abbreviated as "CSI"), hybrid automatic repeat request (Hybrid Automatic Repeat request, abbreviated as "HARQ") information, scheduling request (Scheduling Request, abbreviated as "SR") and the like to the base station through a physical uplink control channel (Physical Uplink Control Channel, abbreviated as "PUCCH") and a physical uplink shared channel (Physical Uplink Shared Channel, abbreviated as "PUSCH"), wherein the hybrid automatic repeat request information may also be simply referred to as acknowledgement (ACK ")/negative acknowledgement (Negative Acknowledgement, abbreviated as" NACK "), or the hybrid automatic repeat request information may also be referred to as hybrid automatic repeat request acknowledgement (HARQ-ACK).

However, in the CA system between base stations, since the data scheduling of the multiple downlink carriers is performed independently by each base station, that is, uplink control information (Uplink Control Information, abbreviated as "UCI") of each carrier is fed back to each base station respectively, in this way, a ue end may transmit UCI on multiple carriers, for example, a case where multiple PUCCHs are simultaneously transmitted, or a case where multiple PUSCH with UCI is transmitted, in this way, a case where the sum of the transmission powers of all uplink channels and/or sounding reference signals (Sounding Reference Signal, abbreviated as "SRS") to be transmitted exceeds the maximum transmission power of the ue may occur, which results in that the information transmission of the ue cannot be performed normally.

Fig. 1 shows a schematic flow chart of a power determination method 100. Wherein the method 100 may be performed by a user equipment. As shown in fig. 1, the method 100 includes:

s110, determining initial transmission power of each transmission object in a transmission object set, wherein the transmission object set comprises all uplink channels and/or SRS to be transmitted;

s120, when the sum of the initial transmission power of each transmission object in the transmission object set is larger than the maximum transmission power, performing power reduction operation based on the priority order of the corresponding information of the transmission objects to acquire the available transmission power of each transmission object in the transmission object set, wherein the sum of the available transmission power of each transmission object in the transmission object set is not larger than the maximum transmission power;

S130, transmitting each transmission object in the transmission object set according to the available transmission power corresponding to each transmission object in the transmission object set.

Specifically, when uplink channels and/or SRS (i.e., a set of transmission objects) corresponding to multiple carriers need to be transmitted simultaneously, the ue may first calculate an initial transmission power of each transmission object in the set of transmission objects, after calculating the initial transmission power of each transmission object, the ue may compare a sum of the initial transmission powers of each transmission object with a maximum transmission power, when the sum of the initial transmission powers of each transmission object is less than or equal to the maximum transmission power, may directly send each transmission object in the set of transmission objects, when the sum of the initial transmission powers of each transmission object is greater than the maximum transmission power, may first determine a priority of each transmission object according to priority order of transmission object correspondence information and corresponding information of each transmission object in the set of transmission objects, and then may perform a power reduction operation according to the priority of each transmission object, thereby obtaining an available transmission power of each transmission object in the set of transmission objects, when the sum of the initial transmission powers of each transmission object is less than or equal to the maximum transmission power, and when the sum of the initial transmission powers of each transmission object in the set of transmission objects is greater than the maximum transmission object, the ue may then need to perform a power reduction operation.

It should be noted that, in the actual implementation process, due to a device or the like, the sum of the available transmission power of each transmission object in the transmission object set may exceed the maximum transmission power of the user equipment in a tiny period of time, but after the device is stabilized, the sum of the available transmission power of each transmission object in the transmission object set is not greater than the maximum transmission power.

In the embodiment of the present invention, the initial transmission power of the transmission object is the transmission power of the transmission object calculated by the user equipment according to the relevant power control rule before performing the power reduction operation, if the sum of the initial transmission powers of the transmission objects to be transmitted of the user equipment does not exceed the maximum transmission power of the user equipment, the user equipment needs to transmit the corresponding transmission object according to the initial transmission power, and if the sum of the initial transmission powers of the transmission objects to be transmitted of the user equipment exceeds the maximum transmission power of the user equipment, the user equipment needs to perform the power reduction operation to obtain the available transmission power of each transmission object.

It should be understood that in the embodiment of the present invention, the available transmission power for a certain transmission object may be equal to or not equal to its initial transmission power, for example, for a transmission object with a higher priority, the available transmission power may be equal to the initial transmission power, and for a transmission object with a lower priority, the available transmission power may be smaller than the initial transmission power.

In the embodiment of the present invention, the uplink channels and/or SRS that need to be transmitted simultaneously and correspond to multiple carriers may be uplink channels and/or SRS that need to be transmitted in the same subframe; however, since the uplink channels and/or SRS corresponding to the plurality of carriers need to be transmitted simultaneously, although they need to be transmitted simultaneously in terms of time, the subframe numbers of the different uplink channels and/or SRS transmissions may not be identical, and thus, the object needing to be transmitted simultaneously may be understood as an object needing to be transmitted within a certain time point or period.

In the embodiment of the present invention, the transmission object set includes all uplink channels and/or SRS to be transmitted means that: in the case that only an uplink channel needs to be transmitted, the transmission object set includes all uplink channels to be transmitted; in the case that only SRS needs to be transmitted, the transmission object set includes all SRS to be transmitted; in the case where the uplink channel and the SRS need to be transmitted simultaneously, the transmission object set includes all the uplink channels and all the SRS to be transmitted.

It should be understood that, in the embodiment of the present invention, the priority order of the information corresponding to the transmission object may be preset, or may be dynamically set by the user equipment according to a high-level configuration, or may be acquired by the user equipment through another way, which is not limited in the embodiment of the present invention.

In an embodiment of the present invention, the prioritization of the information corresponding to the transmission object may include:

In an embodiment of the present invention, performing a power reduction operation based on a prioritization of transmission object correspondence information may include:

determining the priority of each transmission object in the transmission object set according to the priority ordering of the corresponding information of the transmission objects and the corresponding information of each transmission object in the transmission object set;

in all embodiments of the present invention, the corresponding information of the transmission object may refer to a type corresponding to the transmission object, for example, the corresponding type of one transmission object may be a PRACH channel, a PUCCH channel, a PUSCH channel (may be specifically a PUSCH channel carrying UCI and a PUSCH channel not carrying UCI), or an SRS channel; the corresponding information of the transmission object may also refer to information carried by the transmission object, for example, the corresponding information of one transmission object may be uplink control information UCI, PUSCH data or SRS; the transmission object corresponding information may also refer to information of a carrier corresponding to the transmission object, or the like.

And performing a power reduction operation according to the priority of each transmission object in the transmission object set.

In the embodiment of the present invention, the user equipment may determine the priority of each transmission object in the transmission object set only according to the priority ranking of the types of the transmission objects and the type of each transmission object in the transmission object set; the priority of each transmission object in the transmission object set can be determined only according to the priority order of the UCI carried by the transmission object and the UCI carried by each transmission object in the transmission object set; of course, the priority of each transmission object may be determined only according to the priority order of the carriers corresponding to the transmission objects and the carriers corresponding to each transmission object in the transmission object set.

In the embodiment of the present invention, the user equipment may determine the priority of each transmission object according to one of the priority ranking of the type of the transmission object, the priority ranking of the UCI carried by the transmission object, and the priority of the carrier corresponding to the transmission object, and determine the priority of the transmission object with the same priority according to two other types or one of the priority ranking of the type of the transmission object, the priority ranking of the UCI carried by the transmission object, and the priority ranking of the carrier corresponding to the transmission object when the priorities are the same.

For example, the priority of each transmission object in the transmission object set S may be determined according to the priority ranking of the type of the transmission object, if the priorities of the plurality of transmission objects are determined to be the same according to the priority ranking of the type of the transmission object, it is assumed that the plurality of transmission objects with the same priority determined according to the priority ranking of the type of the transmission object form the transmission object set S1, then the priority corresponding to each transmission in the transmission object set S1 is further determined according to the priority ranking of UCI carried by the transmission object, if the priorities of the plurality of transmission objects in the transmission object set S1 are determined to be the same according to the priority ranking of UCI carried by the transmission object, it is assumed that the plurality of transmission objects with the same priority in the transmission object set S1 form the set S2, and then the priority of each transmission object in the set S2 is further determined according to the priority ranking of the carrier wave corresponding to the transmission object. If the plurality of transmission object sets S2 having the same priority among the transmission object sets S1 include PUCCH1 carrying HARQ-ACK transmission and PUCCH2 carrying HARQ-ACK transmission, the plurality of transmission object sets S2 may be ordered according to the number of bits of HARQ-ACK transmitted on PUCCH1 and PUCCH2, for example, PUCCH having a large number of bits of HARQ-ACK has a higher priority than PUCCH having a small number of bits of HARQ-ACK.

For example, the user device may determine the priority of each transport object in the set of transport objects based on the priority ordering of the types of transport objects and the type of each transport object in the set of transport objects;

determining the priority of each of the transmission objects having equal priority based on the priority ordering of the UCI carried by the transmission object and the UCI carried by each of the transmission objects having equal priority when the priority ordering of each of the transmission objects in the transmission object set determined based on the type of the transmission object and the type of each of the transmission objects is the same, or

The priority of each of the transmission objects with equal priority is determined according to the priority order of the carriers corresponding to the transmission objects and the carriers corresponding to each of the transmission objects with equal priority.

In the embodiment of the present invention, the types of the transmission object may be divided into PRACH, PUCCH, PUSCH carrying UCI, PUSCH not carrying UCI, and SRS, and the prioritization of the types of the transmission object may include at least one of the following:

When the PRACH exists, the PRACH has the highest priority;

when the PUCCH and the PUSCH exist simultaneously, the priority of the PUCCH is higher than the priority of the PUSCH, or the priority of the PUCCH is higher than the priority of the PUSCH without UCI and is the same as the priority of the PUSCH with UCI;

when PRACH, PUCCH, PUSCH and SRS coexist, the priority of SRS is lowest.

Specifically, the prioritization of the type of the transmission object may also be: the PRACH is higher than the PUCCH, the PUCCH is higher than the PUSCH carrying UCI, the PUSCH carrying UCI is higher than the PUSCH not carrying UCI, and the PUSCH not carrying UCI is higher than the SRS. Or the prioritization of the type of the transport object may also be: the PRACH priority is higher than the PUCCH priority, the PUCCH priority is equal to the PUSCH priority carrying UCI, the PUSCH priority carrying UCI is higher than the PUSCH priority not carrying UCI, and the PUSCH priority not carrying UCI is higher than the SRS priority.

In the embodiment of the invention, if the priority of the PUCCH is the same as the priority of the PUSCH carrying the UCI, the more important UCI information can be better protected in some application scenes. For example, when UCI carried in PUSCH carrying UCI is HARQ-ACK and UCI carried by PUCCH is channel state information, the priority of PUCCH and the priority of PUSCH carrying UCI are set to be the same, and then the priority is determined by sorting PUCCH and PUSCH carrying UCI with the same priority according to the priority of UCI carried, so that the priority of PUSCH carrying HARQ is determined to be higher, thus the HARQ is protected to a higher level, and the transmission performance of the important information is guaranteed. This benefit can be obtained for the scenario of dual link (Dual connectivity), or for the scenario where UCI may be transmitted simultaneously on multiple uplink carriers, or for the scenario where multiple PUCCHs are allowed to be transmitted simultaneously on multiple carriers.

In the embodiment of the present invention, UCI carried by a transmission object may be divided into hybrid automatic repeat request information, scheduling request and channel state information, where prioritization of UCI carried by a transmission object may include at least one of the following:

In the embodiment of the present invention, the prioritization of UCI carried by the transmission object may include at least one of the following:

It should be understood that, in the embodiment of the present invention, the priority of each transmission object is determined according to the UCI carried by the transmission object, and the priority of each transmission object may be determined according to the priority of the UCI carried by each transmission object and having the greatest priority, for example, UCI information carried by PUCCH channel 1 includes only a scheduling request, UCI information carried by PUCCH channel 2 includes only a channel quality indication and a precoding matrix, so that if the priorities are ordered according to the priority of the content carried and having the greatest priority, the priority of PUCCH channel 1 is higher than the priority of PUCCH channel 2.

In the embodiment of the present invention, the prioritization of the carriers corresponding to the transmission object may include:

at least one of a priority ranking determined based on an index sequence number of a carrier, a carrier priority ranking configured by a higher layer, a priority ranking determined based on a duplex mode of the carrier, a priority ranking determined based on a transmission point corresponding to the carrier, and a priority ranking determined based on an RRC connection condition of the carrier.

In the embodiment of the present invention, the index of the carrier may be preconfigured, and the preconfigured carrier index may be set according to the importance of the carrier relative to the user equipment. If the order is in the order from high to low, that is, the index of the carrier with high importance is small, the priority rule corresponding to the carrier index is the order in which the priority is increased from high to low, that is, the carrier with small carrier index has higher priority. Of course, the order may be sorted according to the order from low importance to high importance, that is, the carrier with high importance has a large index, and the priority rule corresponding to the carrier index is that the order from high importance to low importance may be the order in which the carrier index decreases, that is, the carrier with small carrier index has a lower priority.

In the embodiment of the present invention, the order of the priority orders corresponding to the carriers from high to low may be the order configured by the higher layer, that is, the order of the priority orders may be the order that the higher layer notifies through semi-static signaling.

In the embodiment of the present invention, the carrier may correspond to a corresponding transmission point, or may correspond to a corresponding base station, for example, carrier 1 is from a macro base station, and carrier 2 is from a micro base station, where the carrier priority is the transmission point priority, or is the base station priority. Taking the example that the ue aggregates two uplink carriers, the priority corresponding to the carriers may be higher than the priority of the carriers corresponding to the Macro base stations (Macro). The situation is mainly used for transmitting the radio resource control (Radio Resource Control, abbreviated as "RRC") control information and/or the semi-persistent scheduling (SPS) service of the user equipment, and can realize better protection of the RRC control information and/or the semi-persistent scheduling (Semi Persistent Scheduling, abbreviated as "SPS") service data.

In the embodiment of the present invention, the prioritization of the carriers corresponding to the transmission object may include: the prioritization determined based on the duplexing of the carriers may be, for example, such that the priority of the carriers that are frequency division duplexing (Frequency Division Duplexing, FDD) in the duplexing mode is less than the priority of the carriers that are time division duplexing (Time Division Duplexing, TDD) in the duplexing mode.

Specifically, the prioritization based on the transmission object correspondence information may include at least one of:

the priority of the PUCCH transmitted on the carrier wave with the duplex mode being the frequency division duplex is smaller than that of the PUCCH transmitted on the carrier wave with the duplex mode being the TDD, and at the moment, the PUCCH transmitted on the carrier wave with the duplex mode being the FDD and the PUCCH transmitted on the carrier wave with the duplex mode being the TDD can be the PUCCH carrying the hybrid automatic repeat request information;

the priority of the PUCCH transmitted on the carrier with the duplex mode being FDD is smaller than the priority of the PUSCH carrying UCI transmitted on the carrier with the duplex mode being TDD, and at the moment, the UCI carried by the PUSCH carrying UCI transmitted on the carrier with the duplex mode being TDD comprises the hybrid automatic repeat request information.

In all embodiments of the present invention, when the priority order of the carriers corresponding to the transmission objects is determined by the duplex mode of the carriers, the present invention is beneficial to the scenario of combined TDD and FDD applications. For example, in this scenario, if the PUCCH transmitted on the carrier with duplex mode being FDD and the PUCCH transmitted on the carrier with duplex mode being TDD coexist, and both the PUCCH transmitted on the carrier with duplex mode being FDD and the PUCCH transmitted on the carrier with duplex mode being TDD are PUCCHs carrying hybrid automatic repeat request information, typically, the PUCCH transmitted on the carrier with duplex mode being TDD carries HARQ-ACKs of multiple downlink subframes, and the PUCCH transmitted on the carrier with duplex mode being FDD may only carry HARQ-ACKs of one downlink subframe, then at this time, according to the priority ordering determined based on the carrier duplex mode, the priority of the PUCCH transmitted on the carrier with duplex mode being TDD is higher than the priority of the PUCCH transmitted on the carrier with duplex mode being FDD, thereby ensuring performance of the PUCCH transmitted on the carrier with duplex mode being TDD, so that data of multiple downlink subframes on the carrier with duplex mode being TDD does not need to be retransmitted, and system performance is improved.

In the embodiment of the present invention, the prioritization of the carriers corresponding to the transmission object may include: the prioritization determined based on the RRC connection situation of the carriers may be, for example, higher priority for the carriers supporting RRC connection than for the carriers not supporting RRC connection, or higher priority for the carriers carrying RRC information than for the carriers not carrying RRC information. In the embodiment of the present invention, the ue may determine the priority of the transmission object according to the priority ranking determined based on the RRC connection condition, for example, if carrier 1 is a carrier supporting RRC connection and carrier 2 is a carrier not supporting RRC connection, the priority of carrier 1 is higher than the priority of carrier 2, that is, no matter what types of transmission objects corresponding to carrier 1 and carrier 2 are, or what UCI of transmission objects corresponding to carrier 1 and carrier 2 is, the priority of the transmission object corresponding to carrier 1 is higher than the priority of the transmission object corresponding to carrier 2. When the priority of the transmission object is determined according to the priority ranking determined based on the RRC connection condition, the priority of the transmission object may be further determined according to the priority of the type corresponding to the transmission object and/or the priority of the UCI carried by the transmission object when the transmission object with the same priority still exists.

In the embodiment of the present invention, performing the power reduction operation according to the priority of each transmission object may include:

In the embodiment of the invention, the mode of sequentially carrying out power reduction according to the priority order of the transmission objects from low to high meets the requirement that the available transmission power of the transmission objects with the priority order of n+1 is equal to the initial transmission power under the condition that the available transmission power of the transmission objects with the priority order of n is not 0, wherein m is the number of the transmission objects in the transmission object set, m is not less than or equal to n and not less than 1, and the priority of the transmission objects with the priority order of 1 is the lowest.

That is, after determining the priority of each transmission object based on the priority ranking, power reduction may be performed on the transmission power of the transmission object with the lowest priority first, and if the initial transmission power of the transmission object with the lowest priority can meet the reduction requirement, that is, when the initial transmission power with the lowest priority is greater than the difference between the initial transmission power of each transmission object in the transmission object set and the maximum transmission power of the user equipment, power reduction is performed only on the transmission object with the lowest priority to obtain the available transmission power of the transmission object with the lowest priority, where the available transmission power of other transmission objects is equal to the initial transmission power; if the initial transmission power of the transmission object with the lowest priority can not meet the reduction requirement, firstly carrying out power reduction on the transmission object with the lowest priority to obtain the available transmission power of the transmission object with the lowest priority as 0, then carrying out power reduction on the transmission object with the lowest priority, and if the initial transmission power of the transmission object with the lowest priority can meet the reduction requirement, namely, when the sum of the initial transmission power with the lowest priority and the initial transmission power with the lowest priority is larger than the difference between the initial transmission power of each transmission object in the transmission object set and the maximum transmission power of user equipment, carrying out power reduction on the transmission object with the lowest priority to obtain the available transmission power with the lowest priority, wherein the available transmission power of other transmission objects (other transmission objects except the transmission object with the lowest priority and the transmission object with the lowest priority in the transmission object set) is equal to the initial transmission power; and if the initial transmitting power of the transmission object with the lowest priority can not meet the reduction requirement, performing power reduction on the transmission object with the third highest priority, and so on until the sum of the available transmitting power of each transmission object in the transmission object set is smaller than or equal to the maximum transmitting power of the user equipment.

In the embodiment of the invention, when a plurality of transmission objects exist under the same priority, the equal power reduction can be performed on the plurality of transmission objects under the same priority.

In the embodiment of the present invention, the operation of equal power reduction may be equal power reduction of the objects to be subjected to power reduction in proportion, that is, the ratio of the initial transmission power to the available transmission power of each transmission object subjected to power reduction is the same value. The same value of power may also be subtracted from the initial transmit power of the transmission object that needs to be power reduced.

Assuming that the transmission objects of the same priority that need to perform power reduction include transmission objects A, B and C, the initial transmission power corresponding to transmission object a is a, the initial transmission power corresponding to transmission object B is B, the transmission power of transmission object C is C, and the power that needs to be reduced is d. The equal power reduction operation can be directly performed on all the transmission objects in proportion, i.e. according to the formula

w (a+b+c) =d gives the coefficient w, so that the power of the transmission object ABC that needs to be reduced can be obtained as wa, wb and wc, respectively, i.e. the available transmit powers as a-wa, b-wb and c-wc, respectively. The same value of power may be subtracted from the initial transmit power of the transmission object to be power reduced, i.e., e may be obtained according to the formula 3e=d, where the power of the transmission object A, B, C to be reduced is d/3, i.e., the available transmit powers are a-d/3, b-d/3, and c-d/3, respectively.

It should be appreciated that embodiments of the present invention may also power down the transmission object in accordance with other manners. For example, power reduction may be performed on all transmission objects, for example, according to the formula ma+nb+pc=d, where the numerical relationship among m, n, and p may be determined according to the priority of the corresponding transmission object, so that the transmission power of the transmission object A, B, C may be equal to ma, nb, and pc, respectively.

Of course, in the embodiment of the present invention, power reduction may be performed in other manners, which is not limited by the embodiment of the present invention.

In order to more clearly understand the present invention, the power determining method of the present invention will be described below with reference to several examples, where in the following examples, it is assumed that a ue aggregates two uplink carriers, i.e. carrier 1 and carrier 2, and multiple objects to be transmitted need to be sent on the same subframe, and the sum of the transmission powers of the respective transmission objects is greater than the maximum transmission power of the ue. For convenience of description, the transmit power in the following examples is characterized by a linear value of the transmit power, but may be characterized by other values, for example, an absolute value of the transmit power or a relative value of the transmit power.

Example 1:

the object to be transmitted is PUCCH channel 1 to be transmitted on carrier 1 and PUCCH channel 2 to be transmitted on carrier 2, in this example, only the priorities of the channels are compared, and if the priorities of the two channels are the same, the transmitting power of the two PUCCH channels may be reduced in equal power, and the reduction coefficient may be obtained according to the following formula:

Example 2:

the objects to be transmitted are a PUCCH channel 1 to be transmitted on a carrier 1 and a PUCCH channel 2 to be transmitted on a carrier 2, wherein UCI transmitted by the PUCCH channel 1 is hybrid automatic repeat request information (HARQ) information, and PUUCI transmitted by CCH channel 2 is CQI/PMI, because the two channels are PUCCH channels, the UCI carried by the two channels can be prioritized according to the respective UCI, and because the priority of the hybrid automatic repeat request information is higher than that of CQI/PMI, the priority of PUCCH channel 1 is higher than that of PUCCH channel 2, namely, the transmission power of PUCCH on carrier 2 can be reduced to obtain the available transmission power, thus the linear value of the available transmission power of PUCCH channel 2 on carrier 2 is

Wherein (1)>

Is a linear value of maximum transmit power, +.>

Is a linear value of the available transmit power of PUCCH channel 1 (equal to the linear value of the initial transmit power).

Example 3:

the objects to be transmitted are a PUSCH channel 1 carrying UCI to be transmitted on a carrier 1 and a PUSCH channel 2 carrying UCI to be transmitted on a carrier 2, wherein UCI carried by the PUSCH channel 1 is hybrid automatic repeat request information and CQI/PMI, uplink control information carried by the PUSCH channel 2 is CQI/PMI, and since the two channels are PUSCH, priority ranking can be performed according to UCI carried in the two channels respectively, and since the priority of the hybrid automatic repeat request information is higher than that of CQI/PMI, priority of a PUSCH channel 2 of the PUSCH channel 1, that is, transmission power of PUSCH on the carrier 2 can be reduced to obtain available transmission power, and thus, the available transmission power linear value of the PUSCH channel 2 on the carrier 2 is

Wherein (1)>

Is a linear value of the maximum transmit power,

is the available transmit power (equal to the initial transmit power) for PUSCH channel 1.

Example 4:

in the two uplink carriers aggregated by the user equipment, carrier 1 comes from a macro base station, carrier 2 comes from a micro base station, if the channel to be transmitted by the user equipment of the subframe is two PUSCH channels, the object to be transmitted is PUSCH channel 1 which needs to be transmitted on carrier 1 and PUSCH channel 2 which needs to be transmitted on carrier 2 and does not carry UCI, because carrier 1 comes from the macro base station, carrier 2 comes from the micro base station, the priority of the PUSCH channel 1 is higher than that of the PUSCH channel 2, namely, the transmission power of the PUSCH channel 2 can be reduced to obtain the available transmission power, and therefore, the available transmission power linear value of the PUSCH channel 2 corresponding to the micro base station is

Wherein (1)>

Is a linear value of the maximum transmit power,

is the available transmit power (equal to the linear value of the initial transmit power) for PUSCH channel 1.

Example 5: the object to be transmitted is PUCCH channel 1 to be transmitted on carrier 1 and PUSCH channel 1 to be transmitted on carrier 2 carrying UCI, the channels may be compared, and since the priority of PUCCH channel is higher than that of PUSCH channel, the priority of PUCCH channel 1 is higher than that of PUSCH channel 1, i.e. the transmission power of PUSCH channel 1 may be reduced to obtain the available transmission power, so that the available transmission power linear value of PUSCH channel 1 is

Wherein (1)>

Is a linear value of maximum transmit power, +.>

The available transmit power (equal to the initial transmit power) for PUCCH channel 1.

Example 6: the objects to be transmitted are a PUCCH 1 which needs to be transmitted on a carrier 1, a PUSCH 1 which does not carry UCI and a PUSCH 2 which needs to be transmitted on a carrier 2, wherein the priority of the PUCCH is higher than that of the PUSCH, the power of the PUSCH can be reduced, and the two PUSCH can be subjected to equal power reduction due to the existence of the two PUSCH, so that the available transmitting power of the PUSCH 1 and the PUSCH 2 can be obtained as follows

Wherein (1)>

Is a linear value of maximum transmit power, +.>

Example 7: the objects to be transmitted are a PUCCH channel 1 which needs to be transmitted on a carrier 1 and a PUSCH channel 1 which needs to be transmitted on a carrier 2 and carries UCI, wherein UCI carried by the PUCCH channel 1 is CQI/PMI, and UCI carried by the PUSCH channel 1 is hybrid automatic repeat request information. Firstly, the channels corresponding to the transmission objects can be compared according to the priority ordering of the types of the transmission objects, since the priority of the PUCCH channel is equal to the priority of the PUSCH channel carrying UCI, the UCI carried by the PUCCH channel 1 and the UCI carried by the PUSCH channel 1 are further required to be prioritized according to the priority ordering of the UCI carried by the transmission objects, and since the priority of the hybrid automatic repeat request information is higher than the CQI/PMI, the priority of the PUCCH channel 1 is lower than the priority of the PUSCH channel 1, i.e. the transmission power of the PUCCH on the carrier 1 can be reduced to obtain the available transmission power, therebyThe available transmit power linear value of PUSCH channel 1 on carrier 2 is

Wherein (1)>

Is a linear value of maximum transmit power, +.>

Is a linear value of the available transmit power of PUSCH channel 1 (equal to the linear value of the initial transmit power).

Example 8:

the objects to be transmitted are a PUCCH channel 1 to be transmitted on a carrier 1 and a PUCCH channel 2 to be transmitted on a carrier 2, wherein UCI transmitted by the PUCCH channel 1 is hybrid automatic repeat request information, UCI transmitted by the PUCCH channel 2 is also hybrid automatic repeat request information, wherein the carrier 1 is a carrier with a duplex mode of FDD, and the carrier 2 is a carrier with a duplex mode of TDD. Firstly, the channels corresponding to the transmission objects can be compared according to the priority ordering of the types of the transmission objects, since the two channels are both PUCCH channels, the UCI carried by PUCCH channel 1 and UCI carried by PUCCH channel 2 need to be further prioritized according to the priority ordering of UCI carried by the transmission objects, since both channels carry hybrid automatic repeat request information, the carrier 1 corresponding to PUCCH channel 1 and carrier 2 corresponding to PUCCH channel 2 need to be further prioritized according to the priority ordering of the carriers corresponding to the transmission objects, since the duplex mode of the carrier 1 corresponding to PUCCH channel 1 is FDD, the duplex mode of the carrier 2 corresponding to PUCCH channel 2 is TDD, the priority of the carrier 2 corresponding to PUCCH channel 2 is higher than the carrier 1 corresponding to PUCCH channel 1, that is, the priority of the PUCCH channel 2 is higher than the priority of PUCCH channel 1, that is, the transmit power of PUCCH on PUCCH 1 can be reduced to obtain the available transmit power, and thus the available transmit power linear value of PUCCH channel 1 is the available transmit power

Wherein (1)>

Is a linear value of maximum transmit power, +.>
