Description

Power determination method, user equipment and base station

Technical Field

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

Background

The Long Term Evolution-Advanced (Long Term Evolution-Advanced, abbreviated "LTE-a") system is a further Evolution and enhancement system of the third Generation Partnership Project (3rd Generation Partnership Project, abbreviated "3 GPP") Long Term Evolution (Long Term Evolution, abbreviated "LTE") system. In the LTE-a system, in order to meet the peak data rate requirement of the international telecommunication union for the fourth generation communication technology, a Carrier Aggregation (CA) technology, also called a Spectrum Aggregation (Spectrum Aggregation) technology or a bandwidth extension (bandwidth extension) technology, is introduced. In Carrier aggregation, the frequency spectrums of two or more Component carriers (Component carriers) are aggregated together to obtain a wider transmission bandwidth, and the frequency spectrums of the Component carriers can be adjacent continuous frequency spectrums, non-adjacent frequency spectrums in the same frequency band or even discontinuous frequency spectrums in different frequency bands; an LTE Rel-8/9 user equipment (user equipment, abbreviated as "UE") can only access one of the component carriers for data transceiving, and an LTE-a user equipment can simultaneously access a plurality of component carriers for data transceiving according to its capability and service requirements.

In order to support technologies such as dynamic scheduling, downlink Multiple Input Multiple Output (MIMO) transmission, Hybrid Automatic Repeat request (SR), and the like, a terminal needs to feed back various Uplink Control Information (UCI) including Channel State Information (CSI), Hybrid Automatic Repeat request (HARQ) Information, Scheduling Request (SR), and the like to a base station through a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH), wherein, the harq information can also be referred to as Acknowledgement (ACK) or Negative Acknowledgement (NACK), or 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 data scheduling of multiple downlink carriers is performed independently by each base station, that is, Uplink Control Information (UCI) of each carrier is fed back to each base station, so that a ue end may transmit UCI on multiple carriers, for example, multiple PUCCHs may be transmitted simultaneously or multiple PUSCHs with UCI may be transmitted, and thus, the sum of the transmission powers of all Uplink channels to be transmitted and/or Sounding Reference Signals (SRS) may exceed the maximum transmission power of the ue, and Information transmission of the ue may not be performed normally.

Fig. 1 shows a schematic flow diagram 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 the initial transmitting 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 transmitting power of each transmitting object in the transmitting object set is greater than the maximum transmitting power, based on the priority sequence of the corresponding information of the transmitting objects, executing a power reduction operation to obtain the available transmitting power of each transmitting object in the transmitting object set, wherein the sum of the available transmitting power of each transmitting object in the transmitting object set is not greater than the maximum transmitting power;

s130, sending 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 SRSs (i.e., a transmission object set) corresponding to multiple carriers need to be transmitted simultaneously, the ue may first calculate an initial transmit power of each transmission object in the transmission object set, after calculating the initial transmit power of each transmission object, the ue may compare the sum of the initial transmit powers of each transmission object with a maximum transmit power, when the sum of the initial transmit powers of each transmission object is less than or equal to the maximum transmit power, each transmission object in the transmission object set may be directly transmitted, and when the sum of the initial transmit powers of each transmission object is greater than the maximum transmit power, a power reduction operation needs to be performed, specifically, the ue may first sort the transmission object corresponding information according to a priority of the transmission object corresponding information and the transmission object corresponding information of each transmission object in the transmission object set, determining the priority of each transmission object, then performing a power reduction operation according to the priority of each transmission object, thereby obtaining an available transmission power of each transmission object in the transmission object set, wherein the sum of the available transmission powers of each transmission object in the transmission object set is not greater than the maximum transmission power, and after obtaining the available transmission power of each transmission object in the transmission object set, the user equipment may send each transmission object in the transmission object set according to the available transmission power corresponding to each transmission object in the transmission object set.

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

In the embodiment of the present invention, the initial transmission power of a 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 the initial transmission power thereof, for example, for a transmission object with higher priority, the available transmission power may be equal to the initial transmission power, and for a transmission object with lower priority, the available transmission power is smaller than the initial transmission power.

In the embodiment of the present invention, the uplink channels and/or SRSs corresponding to multiple carriers that need to be transmitted simultaneously may be uplink channels and/or SRSs corresponding to multiple carriers that need to be transmitted in the same subframe; however, for uplink channels and/or SRSs corresponding to a plurality of carriers that need to be transmitted simultaneously, although they need to be transmitted simultaneously in terms of time, subframe numbers sent by different uplink channels and/or SRSs may not be consistent, and therefore, objects that need to be transmitted simultaneously may also be understood as objects that need to be transmitted at a certain time point or within a certain time period.

In the embodiment of the present invention, the transmission object set includes all uplink channels and/or SRSs to be transmitted, which means that: under the condition that only the uplink channel needs to be transmitted, the transmission object set comprises all the uplink channels to be transmitted; under the condition that only the SRS needs to be transmitted, the transmission object set comprises all the SRSs to be transmitted; under the condition that the uplink channel and the SRS need to be transmitted simultaneously, the transmission object set comprises all uplink channels to be transmitted and all SRSs.

It should be understood that, in the embodiment of the present invention, the priority ranking 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 obtained by the user equipment through other approaches, and the embodiment of the present invention does not limit this.

In this embodiment of the present invention, the priority ranking of the information corresponding to the transmission object may include:

In this embodiment of the present invention, the performing the power reduction operation based on the priority ranking of the information corresponding to the transmission object may include:

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 (which may specifically be a PUSCH channel carrying UCI and a PUSCH channel not carrying UCI), or an SRS channel; the information corresponding to the transmission object may also refer to information carried by the transmission object, for example, the information corresponding to one transmission object may be uplink control information UCI, PUSCH data, or SRS; the correspondence information of the transmission target may also refer to information of a carrier corresponding to the transmission target, and the like.

A power reduction operation is performed based on the priority of each transport object in the set of transport objects.

In the embodiment of the present invention, the user equipment may determine the priority of each transport object in the transport object set only according to the priority ranking of the types of the transport objects and the type of each transport object in the transport object set; or determining the priority of each transmission object in the transmission object set according to the priority ordering 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 also be determined only according to the priority ranking of the carriers corresponding to the transmission objects and the carrier corresponding to each transmission object in the transmission object set.

In the embodiment of the present invention, the user equipment may also determine the priority of each transmission object according to one of the priority ranking of the types of the transmission objects, the priority ranking of the UCI carried by the transmission objects, and the priority of the carrier corresponding to the transmission objects, and determine the priority of the transmission objects with the same priority according to other two or one of the priority ranking of the types of the transmission objects, the priority ranking of the UCI carried by the transmission objects, and the priority ranking of the carrier corresponding to the transmission objects, 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 order of the types of the transmission objects, if the priorities of the transmission objects are determined to be the same according to the priority order of the types of the transmission objects, it is assumed that the transmission objects with the same priority determined according to the priority order of the types of the transmission objects 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 order of the UCI carried by the transmission objects, if the priorities of the transmission objects in the transmission object set S1 are determined to be the same according to the priority order of the UCI carried by the transmission objects, it is assumed that the 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 order of the priorities of the carriers corresponding to the transmission objects. For a plurality of transmission object sets S2 with the same priority in the transmission object set S1, if the PUCCH1 carrying HARQ-ACK transmission and the PUCCH2 carrying HARQ-ACK transmission are included in S2, they may also be sorted according to the number of bits of HARQ-ACK transmitted on PUCCH1 and PUCCH2, for example, the PUCCH with the larger number of bits of HARQ-ACK has higher priority than the PUCCH with the smaller number of bits of HARQ-ACK.

For example, the user equipment may determine the priority of each transport object in the set of transport objects according to the priority ranking of the types of transport objects and the type of each transport object in the set of transport objects;

when the priority ranking of each transmission object in the transmission object set determined according to the type of the transmission object and the type of each transmission object are the same, determining the priority of each transmission object in the transmission objects with the equal priority according to the priority ranking of UCI carried by the transmission objects and the UCI carried by each transmission object in the transmission objects with the equal priority, or

And determining the priority of each transmission object in the transmission objects with the equal priority according to the priority sequence of the carriers corresponding to the transmission objects and the carrier corresponding to each transmission object in the transmission objects with the equal priority.

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

when the PRACH exists, the priority of the PRACH is highest;

when the PUCCH and the PUSCH exist simultaneously, the priority of the PUCCH is higher than that of the PUSCH, or the priority of the PUCCH is higher than that of the PUSCH not carrying UCI and is the same as that of the PUSCH carrying UCI;

Specifically, the priority ordering of the types of the transmission objects may also be: the priority of the PRACH is higher than that of the PUCCH, the priority of the PUCCH is higher than that of the PUSCH carrying the UCI, the priority of the PUSCH carrying the UCI is higher than that of the PUSCH not carrying the UCI, and the priority of the PUSCH not carrying the UCI is higher than that of the SRS. Or the priority ordering of the types of the transmission objects can also be: the priority of the PRACH is higher than that of the PUCCH, the priority of the PUCCH is equal to that of the PUSCH carrying the UCI, the priority of the PUSCH carrying the UCI is higher than that of the PUSCH not carrying the UCI, and the priority of the PUSCH not carrying the UCI is higher than that of the SRS.

In the embodiment of the invention, if the priority of the PUCCH is the same as that of the PUSCH carrying the UCI, 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, priority of PUCCH and priority of PUSCH carrying UCI are set to be the same, and then priority is determined for PUCCH and PUSCH carrying UCI having the same priority according to priority ordering of the UCI carried, that is, it can be determined that the priority of PUSCH carrying HARQ information is higher, so that HARQ information is protected higher, and transmission performance of important information of this type is guaranteed. This beneficial effect can be obtained for a Dual connectivity (Dual connectivity) scenario, or for a scenario in which UCI can be transmitted on multiple uplink carriers simultaneously, or for a scenario in which multiple PUCCHs are allowed to be transmitted on multiple carriers simultaneously.

In this embodiment of the present invention, UCI carried by a transport object may be divided into harq information, scheduling request, and csi, where the priority ordering of UCI carried by the transport object may include at least one of:

In this embodiment of the present invention, the priority ordering of UCI carried by the transport 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 transport object is determined according to the UCI carried by the transport object, and the priority of each transport object may be determined according to the priority of the UCI with the largest priority carried by each transport object, for example, the UCI information carried by PUCCH channel 1 only includes a scheduling request, and the UCI information carried by PUCCH channel 2 only includes a channel quality indication and a precoding matrix, so that if the UCI information carried by the content with the largest priority is sorted according to the priority of the content with the largest priority, the priority of PUCCH channel 1 is higher than the priority of PUCCH channel 2.

In this embodiment of the present invention, the prioritizing of the carriers corresponding to the transmission objects may include:

at least one of priority ordering determined based on the index sequence number of the carrier, carrier priority ordering configured by a higher layer, priority ordering determined based on the duplex mode of the carrier, priority ordering determined based on the transmission point corresponding to the carrier and priority ordering determined based on the 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 with respect to the user equipment. If the carriers are sorted in the order of importance from high to low, that is, the indexes of the carriers with high importance are small, the priority rule corresponding to the carrier indexes is that the priority is in the order of increasing the carrier indexes from high to low, that is, the carriers with small carrier indexes have higher priority. Of course, the carriers may be sorted according to the order from low to high in importance, that is, the index of the carrier with high importance is large, the priority rule corresponding to the carrier index is that the order of priority from high to low may be the order of decreasing carrier index, that is, the carrier with small carrier index has lower priority.

In the embodiment of the present invention, the priority ranking corresponding to the carriers may be a sequence configured by a higher layer from high to low, that is, the priority ranking may be a sequence notified by a semi-static signaling by the higher layer.

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, the carrier 1 is from a macro base station, and the carrier 2 is from a micro base station, where the carrier priority is the transmission point priority, or the base station priority. Taking the example that the user equipment aggregates two uplink carriers, the priority corresponding to the carriers may be that the priority of the carrier corresponding to the Macro base station (Macro) is higher than the priority of the carrier corresponding to the micro base station (Pico). This situation is mainly used in a scenario when Radio Resource Control (RRC) Control information and/or SPS service is transmitted, and better protection of RRC Control information and/or SPS service data can be achieved at this time.

In this embodiment of the present invention, the prioritizing of the carriers corresponding to the transmission objects may include: the priority ranking determined based on the duplex mode of the carriers may be, for example, that the priority of the carrier with the duplex mode being Frequency Division Duplex (FDD) is smaller than the priority of the carrier with the duplex mode being Time Division Duplex (TDD).

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

the priority of the PUCCH transmitted on the carrier with the duplex mode of frequency division duplex is smaller than that of the PUCCH transmitted on the carrier with the duplex mode of TDD, and the PUCCH transmitted on the carrier with the duplex mode of FDD and the PUCCH transmitted on the carrier with the duplex mode of TDD can be the PUCCH carrying 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 this time, the UCI carried by the PUSCH carrying UCI transmitted on the carrier with the duplex mode being TDD includes harq information.

In all embodiments of the present invention, when the priority ranking of the carrier corresponding to the transmission object is the priority ranking determined based on the duplex mode of the carrier, it is beneficial to the scenario of TDD and FDD combined application. For example, in this scenario, if the PUCCH transmitted on the carrier in the FDD mode and the PUCCH transmitted on the carrier in the TDD mode coexist, and both the PUCCH transmitted on the carrier in the FDD mode and the PUCCH transmitted on the carrier in the TDD mode are PUCCHs carrying HARQ-ACKs of multiple downlink subframes, while the PUCCH transmitted on the carrier in the FDD mode may carry only HARQ-ACK of one downlink subframe, then the PUCCH transmitted on the carrier in the TDD mode is prioritized based on the carrier duplexing mode, and the priority of the PUCCH transmitted on the carrier in the TDD mode is higher than the priority of the PUCCH transmitted on the carrier in the FDD mode, so that the performance of the PUCCH transmitted on the carrier in the TDD mode is ensured, and data of multiple downlink subframes on the carrier in the TDD mode does not need to be retransmitted, the system performance is improved.

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

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

and executing power reduction operation in a mode of sequentially reducing the power of each transmission object in the transmission object set from low to high according to the priority order of each transmission object in the transmission object set until the sum of the obtained available transmitting power of each transmission object in the transmission object set is less than or equal to the maximum transmitting power.

In the embodiment of the present invention, the manner of sequentially performing power reduction from low to high according to the priority order of the transmission objects 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 with the priority order of n is not 0, where m is the number of the transmission objects in the transmission object set, m is greater than or equal to n greater than or equal to 1, and the transmission objects with the priority order of 1 have the lowest priority.

That is, after determining the priority of each transmission object based on the priority ranking, the transmission power of the transmission object with the lowest priority may be reduced first, and if the initial transmission power of the transmission object with the lowest priority can meet the reduction requirement, that is, if the initial transmission power of the transmission object 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, only the transmission object with the lowest priority is reduced in power to obtain the available transmission power of the transmission object with the lowest priority, and the available transmission powers of other transmission objects are equal to the initial transmission power; if the initial transmitting power of the transmission object with the lowest priority can not meet the reduction requirement, the transmission object with the lowest priority is subjected to power reduction to obtain that the available transmitting power of the transmission object with the lowest priority is 0, and then, the power of the transmission object with low priority is reduced, if the initial transmission power of the transmission object with low priority can meet the reduction requirement, that is, when the sum of the initial transmission power with the lowest priority and the initial transmission power with the next 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, performing power reduction on the transmission object with the lower priority to obtain the available transmission power with the lower priority, wherein the available transmission power of other transmission objects (the transmission objects except the transmission object with the lower priority and the transmission object with the lowest priority in the transmission object set) is equal to the initial transmission power; if the initial transmission power of the transmission object with the lower priority can not meet the reduction requirement, the transmission object with the third lowest priority is subjected to power reduction, and the like, until the sum of the available transmission power of each transmission object in the transmission object set is equal to the maximum transmission power of the user equipment.

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

In the embodiment of the present invention, the operation of power reduction may be to scale the objects to be power reduced, 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 amount of power may also be subtracted from the initial transmit power of the transmitting 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 the scale of all the transmission objects, i.e. it can be formulated

The coefficient w is obtained by w (a + b + c) ═ d, so that the powers of the transmission object ABC that need to be reduced are wa, wb, and wc, respectively, i.e., the available transmit powers are a-wa, b-wb, and c-wc, respectively, can be obtained. If the same power is subtracted from the initial transmit power of the transmission object that needs to be power-reduced, i.e., if e is obtained according to equation 3e ═ d, then the power that needs to be reduced by the transmission object A, B, C is d/3, i.e., the available transmit powers are a-d/3, b-d/3, and c-d/3, respectively.

It should be understood that the power reduction of the transmission object may be performed according to other manners. For example, all transport objects may be power-reduced, for example, according to the formula ma + nb + pc ═ D, where the numerical relationship between m, n, and p may be determined according to the priorities of the corresponding transport objects, so that the transmission power to the transport object A, B, C may be respectively ma, nb, and pc.

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

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 needs to send multiple objects to be transmitted on the same subframe, and the sum of the transmission powers of the 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, such as an absolute value of the transmit power or a relative value of the transmit power.

Example 1:

the object to be transmitted is a PUCCH channel 1 that needs to be transmitted on carrier 1 and a PUCCH channel 2 that needs to be transmitted on carrier 2, in this example, only the priorities of the channels are compared, and then the priorities of the two channels are the same, so that the transmit powers of the two PUCCH channels can be reduced with equal power, and the reduction coefficient can be obtained according to the following formula:

wherein

Wherein,

is a linear value of the 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:

objects to be transmitted are a PUSCH (physical uplink shared channel) 1 carrying UCI (uplink control information) and a PUSCH 2 carrying UCI, wherein the PUSCH 1 carries UCI and the PUSCH 2 carries UCI, the PUSCH 1 carries UCI and CQI/PMI, the PUSCH 2 carries uplink control information which is CQI/PMI, priority sequencing can be carried out according to the UCI carried in the two channels because the two channels are PUSCHs, priority of the PUSCH 2 of the PUSCH 1 is higher than that of the CQI/PMI, namely, the transmitting power of the PUSCH on the carrier 2 can be reduced to obtain available transmitting power, and therefore, the linear value of the available transmitting power of the PUSCH 2 on the carrier 2 is

Wherein,

is a linear value of the maximum transmit power,

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

Example 4:

in two uplink carriers aggregated by the user equipment, a carrier 1 is from a macro base station, a carrier 2 is from a micro base station, and if a channel to be transmitted by the sub-frame user equipment is two PUSCH channelsThe objects to be transmitted are a PUSCH (physical uplink shared channel) 1 which needs to be transmitted on a carrier 1 and does not carry UCI and a PUSCH 2 which needs to be transmitted on a carrier 2 and does not carry UCI, the carrier 1 is from a macro base station, and the carrier 2 is from a micro base station, so that the priority of the PUSCH 1 is higher than that of the PUSCH 2, namely, the transmitting power of the PUSCH 2 can be reduced to obtain available transmitting power, and therefore, the linear value of the available transmitting power of the PUSCH 2 corresponding to the micro base station is equal to

Wherein,

is a linear value of the maximum transmit power,

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

Example 5: the object to be transmitted is a PUCCH (physical uplink control channel) 1 which needs to be transmitted on a carrier wave 1 and a PUSCH (physical uplink shared channel) 1 which needs to be transmitted on a carrier wave 2 and carries UCI (uplink control information), the channels can be compared, the priority of the PUCCH1 is higher than that of the PUSCH 1 because the priority of the PUCCH is higher than that of the PUSCH, namely, the transmitting power of the PUSCH 1 can be reduced to obtain the available transmitting power, and therefore the linear value of the available transmitting power of the PUSCH 1 is equal to

Wherein,

is a linear value of the maximum transmit power,

is the available transmit power of PUCCH channel 1 (equal to the initial transmit power).

Example 6: the objects to be transmitted are PUCCH channel 1 which needs to be transmitted on carrier 1, PUSCH channel 1 which does not carry UCI and PUSCH channel 1 which needs to be transmitted on carrier 2The PUSCH channel 2 of the UCI may be power-reduced because the priority of the PUCCH channel is greater than the priority of the PUSCH channel, and may be power-reduced equally because there are two PUSCH channels, so that the available transmission power of the PUSCH channel 1 and the PUSCH channel 2 may be obtained as

Wherein,

is a linear value of the 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 the UCI carried by the PUCCH channel 1 is CQI/PMI, and the 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 sequence of the types of the transmission objects, since the priority of the PUCCH is equal to the priority of the PUSCH carrying UCI, the priority sequence of the UCI carried by the PUCCH1 and the priority sequence of the UCI carried by the PUSCH 1 need to be further performed, since the priority of the hybrid automatic repeat request information is higher than the CQI/PMI, the priority of the PUCCH1 is lower than the priority of the PUSCH 1, that is, the transmitting power of the PUCCH on the carrier 1 can be reduced to obtain the available transmitting power, so that the linear value of the available transmitting power of the PUSCH 1 on the carrier 2 is equal to the linear value of the available transmitting power of the PUSCH 1 on the carrier 2

Wherein,

is a linear value of the 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:

objects to be transmitted are a PUCCH channel 1 which needs to be transmitted on a carrier 1 and a PUCCH channel 2 which needs to be transmitted on a carrier 2, where 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, where the carrier 1 is a carrier in which a duplex mode is FDD, and the carrier 2 is a carrier in which a duplex mode is TDD. Firstly, the channels corresponding to the transmission objects can be compared according to the priority sequence of the types of the transmission objects, since the two channels are both PUCCH channels, UCI carried by PUCCH channel 1 and UCI carried by PUCCH channel 2 need to be further prioritized according to the priority sequence of UCI carried by the transmission objects, since both channels carry harq information, carrier 1 corresponding to PUCCH channel 1 and carrier 2 corresponding to PUCCH channel 2 need to be further prioritized according to the priority sequence of the carriers corresponding to the transmission objects, since the duplex mode of carrier 1 corresponding to PUCCH channel 1 is FDD and the duplex mode of carrier 2 corresponding to PUCCH channel 2 is TDD, the priority of carrier 2 corresponding to PUCCH channel 2 is higher than that of carrier 1 corresponding to PUCCH channel 1, that is, the priority of PUCCH channel 2 is higher than that of PUCCH channel 1, that is, the transmit power of the PUCCH on carrier 1 may be reduced to obtain the available transmit power, such that the linear value of the available transmit power of PUCCH channel 1 on carrier 1 is

Wherein,
