Mode four:

In embodiment of the present invention which, subscriber equipment can be according to the letter needing transmission in same subframe The priority of the physical uplink channel resource that channel state information report is corresponding, determines the channel status reported Information CSI.

Alternatively, subscriber equipment determines the CSI reported, including:

When needing at least one CSI report correspondence Same Physical to be reported that same subframe reports During row channel resource, the whole CSI report in the CSI report that at least one is to be reported by this are defined as this The CSI reported；

When at least one CSI report correspondence at least two thing to be reported that needs report in same subframe During reason uplink channel resources, with the physics of limit priority in the CSI report that at least one is to be reported by this All or part of CSI report that uplink channel resources is corresponding is defined as this CSI reported.

Preferably, in the CSI report that at least one is to be reported by this, the physical uplink with limit priority is believed Whole CSI report corresponding to road resource are defined as this CSI reported.Preferably, this limit priority Physical uplink channel resource is in this at least two physical uplink channel resource, has the upper of limit priority Report the physical uplink channel resource that the CSI report of type is corresponding, or there is the descending load of minimum carrier index The physical uplink channel resource that the CSI report of ripple is corresponding.

Such as, if the corresponding identical PUCCH resource of X CSI report that X descending carrier is corresponding, The CSI then reported is X the CSI report that this X descending carrier is corresponding；If this X descending load X the CSI report correspondence at least two PUCCH resource that ripple is corresponding, then the CSI reported is this extremely Lack two all or part of CSI reports corresponding to the highest PUCCH resource of PUCCH resource medium priorities Accuse.For example, it is possible to one of as follows determine that at least two PUCCH resource medium priority is the highest PUCCH resource:

Method one: that CSI that X CSI report medium priority that this X descending carrier is corresponding is the highest The PUCCH resource that report is corresponding is the highest for this at least two PUCCH resource medium priority PUCCH resource.That CSI report that X CSI report medium priority is the highest is this X CSI report That CSI report that in announcement, the priority of reporting types is the highest, if the CSI report of a descending carrier The priority phase of priority and the reporting types of the CSI report of another descending carrier of reporting types With, then the CSI report priority having the descending carrier of less carrier index corresponding is higher.Distinguishingly, If the priority of the reporting types of X the CSI report that all X descending carriers are corresponding is the most identical, then That CSI report that X CSI report medium priority is the highest is to have the descending carrier of minimum carrier index CSI report.If part CSI report is upper in X the CSI report that this X descending carrier is corresponding The priority of report type is identical, then first determine, according to reporting types priority, the CSI report that priority is the highest Accuse, however, it is determined that the highest CSI report of priority have multiple, the most again in the plurality of reporting types priority Using that CSI report corresponding with having minimum carrier index as X in the most much higher CSI report That CSI report that individual CSI report medium priority is the highest.

In which, determine at least two PUCCH resource medium priority by the method (method one) The highest PUCCH resource, so that it is determined that the method for the channel condition information CSI reported, can be equivalent to: K channel condition information CSI report in this X channel condition information CSI report is defined as this The channel condition information CSI report reported, this K channel condition information CSI report includes having The channel condition information CSI report of high priority reporting types, and this K channel condition information CSI report Announcement has same physical uplink control channel resource.

Method two: the PUCCH that in this at least two PUCCH resource, corresponding variable number is minimum or most Resource is the PUCCH resource that priority is the highest.

In which, determine at least two PUCCH resource medium priority by the method (method two) The highest PUCCH resource, so that it is determined that the method for the channel condition information CSI reported, can be equivalent to: K channel condition information CSI report in this X channel condition information CSI report is defined as this The channel condition information reported, this K channel condition information CSI report has same physical upload control Channel resource, and the value of this K is the channel condition information that all physical uplink control channel resources are corresponding Maximum in CSI report number.

Method three: in this at least two PUCCH resource, the total information bit number of corresponding CSI report is minimum PUCCH resource be the PUCCH resource that priority is the highest.PUCCH resource correspondence CSI report Total information bit number refer to CSI report total of at least one descending carrier corresponding to this PUCCH resource Information bit.

Should be understood that the embodiment of the present invention can also determine the physical uplink of limit priority according to other factors Channel resource, and this physical uplink channel resource is not limited to PUCCH resource, it is also possible to include it His resource, such as PUSCH resource etc..

Should be understood that in S110, under carrier aggregation scene, base station can be quiet by high-level signaling half The cycle CSI that the state each descending carrier of configuration is corresponding reports pattern, report cycle, sub-frame offset and money Source indexes.Subscriber equipment can according to the report cycle corresponding to each descending carrier of high-level signaling instruction and Sub-frame offset, determines that current CSI reports the moment to need to report X the descending carrier of CSI, wherein, X1 is positive integer；Subscriber equipment can also be further according to each descending carrier pair of high-level signaling instruction The cycle CSI answered reports pattern, determines the CSI that in this X descending carrier, each descending carrier is corresponding The reporting types of report；Subscriber equipment can also be further according to descending load each in this X descending carrier The reporting types of the CSI report of ripple, knows in this X descending carrier on the CSI of each descending carrier Report content, i.e. knows the CSI report (Report) that in this X descending carrier, each descending carrier is corresponding； Subscriber equipment can also be further according to the CSI report that each descending carrier in this X descending carrier is corresponding Accuse, further determine that the information bit of the CSI report that each descending carrier is corresponding in this X descending carrier Number；Subscriber equipment can also report the moment to need to report CSI according to this each CSI determined further In the CSI that in X descending carrier of report, this X descending carrier, each descending carrier is corresponding reports Perhaps the information bit of the CSI report of each descending carrier in this X descending carrier, knows further The total information bit number of X the CSI report that this X descending carrier is corresponding.Subscriber equipment can also enter One step, according to the information bit of the CSI report of each descending carrier in this X descending carrier, determines this The X2 that in X descending carrier, any X2 (X2 is positive integer and X2 ＜ X) individual descending carrier is corresponding Total information bit of CSI report.Subscriber equipment can also according to high-level signaling instruction each descending The resource instruction that carrier wave is corresponding, knows the PUCCH resource that the CSI report of each carrier wave is corresponding.This X PUCCH format corresponding to X CSI report that individual descending carrier is corresponding can be identical, is the most all PUCCH format 3；The PUCCH lattice that X CSI report that this X descending carrier is corresponding is corresponding Formula can also differ, can be such as that in this X descending carrier, Y descending carrier is corresponding Y PUCCH format corresponding to CSI report is PUCCH format 3, remains X-Y carrier wave corresponding PUCCH format corresponding to X-Y CSI report is PUCCH format 2.

PUCCH resource corresponding to X CSI report that this X descending carrier is corresponding can be identical, It is the most all PUCCH format 3, and resource index corresponding to the CSI report of each carrier wave is the most identical, Or be all PUCCH format 2, and resource index corresponding to the CSI report of each carrier wave is the most identical； The PUCCH resource that the CSI report of this X descending carrier is corresponding can also differ, such as, can be The PUCCH resource that in this X descending carrier, the CSI report of Y descending carrier is corresponding is first PUCCH resource, the PUCCH resource that the CSI report of X-Y carrier wave of residue is corresponding is second PUCCH resource.The first PUCCH resource form corresponding with the second PUCCH resource can be different, Form corresponding to the such as first PUCCH resource is PUCCH format 3, the second PUCCH resource pair The form answered is PUCCH format 2；First PUCCH resource is corresponding with the second PUCCH resource PUCCH format can also be identical but resource index different, and such as PUCCH format can be all PUCCH format 3, but resource index corresponding to the first PUCCH resource is 10, the 2nd PUCCH Resource index corresponding to resource is 12.The value of resource index can be 0 to 512.

Outside should be understood that divided by upper several ways, in embodiment of the present invention step S110, it is possible to use it His method determines the CSI reported.

Therefore, the method for the transmitting channel state information of the embodiment of the present invention, it is possible to realize at same height Frame transmission is from the channel condition information of different descending carriers, and needs to pass in same subframe by consideration The reporting types of defeated channel status information reports and/or quantity, the capacity of corresponding physical uplink channel, The factors such as the attribute of descending carrier, the priority of physical uplink channel resource, number of coded bits, it is possible to protect The performance requirement of the channel condition information of card transmission, and high-power utilization ratio can be put forward；And this The method of inventive embodiments, additionally it is possible to improve the property of the channel condition information of the higher reporting types of priority Energy.

In S120, subscriber equipment is sent to base station by the physical uplink channel of such as PUCCH should The CSI reported.Alternatively, this CSI reported should be sent by physical uplink channel to base station, including: Subscriber equipment carries out chnnel coding to the CSI report in this CSI reported, and obtains CSI and encodes information； This CSI coding information is modulated by subscriber equipment, obtains CSI modulation symbol；Subscriber equipment should CSI modulation symbol is mapped on this physical uplink channel and is sent to this base station.

Alternatively, subscriber equipment sends this CSI reported by physical uplink channel to base station, also includes: CSI report in this CSI reported is ranked up by subscriber equipment, obtains CSI information bit sequence； Subscriber equipment carries out chnnel coding to the CSI report in this CSI reported, including: to this CSI information Bit sequence carries out chnnel coding, obtains CSI and encodes information.

Below in conjunction with Fig. 2, another embodiment of the present invention is described in detail.As in figure 2 it is shown, according to The method of the transmitting channel state information of the embodiment of the present invention includes:

In S210, subscriber equipment determines the channel condition information CSI reported, the CSI bag that this reports Include each CSI report at least one CSI report, and this at least one CSI report respectively with one Descending carrier is corresponding.This step S210 is similar to the S110 shown in Fig. 1, for sake of simplicity, at this no longer Repeat.

In S220, the CSI report in this CSI reported is ranked up by subscriber equipment, obtains CSI Information bit sequence.Where it is assumed that the CSI reported includes K CSI report, subscriber equipment is to this CSI report in the CSI reported is ranked up, i.e. K the CSI report reported is entered by subscriber equipment Row sequence, refers to that K CSI report is cascaded according to default rule by subscriber equipment and obtains reporting The information bit sequence that CSI is corresponding, i.e. CSI information bit sequence.Specifically, this step can be by as follows CSI report in a pair of mode this CSI reported is ranked up:

Mode one:

Alternatively, the order that subscriber equipment is incremented by according to the priority of the reporting types of CSI report, to this CSI report in the CSI reported is ranked up, if the priority of the reporting types of CSI report is identical, The order then successively decreased according to the carrier index of descending carrier corresponding to CSI report is ranked up.Specifically, first K CSI report is ranked up by the order being incremented by according to the priority of the reporting types of CSI report, If the priority of the reporting types of part CSI report is identical in K CSI report, then report according to CSI This part CSI report is ranked up by the order that the carrier index of the descending carrier accusing correspondence is successively decreased.Special Ground, when the priority of the reporting types of K CSI report is the most identical, only need to be according to CSI report pair K CSI report is ranked up by the order that the carrier index of the descending carrier answered is successively decreased.Use this sequence During method, if the total information bit number of this K CSI report is more than 11 bits and is odd number, this row Sequence method can improve the performance of the channel condition information of the higher reporting types of priority, thus ensure as far as possible The performance of the CSI report that performance requirement is high.

It should be noted that in step S210 (i.e. step S110) uses mode two to mode four When any one mode determines the CSI reported, if this step (step S220) uses which on this CSI report in the CSI of report is ranked up, and can improve the channel shape of the higher reporting types of priority The performance of state information, thus ensure the performance of the CSI report that performance requirement is high as far as possible.

Mode two:

Should be understood that subscriber equipment can also be incremented by according only to the attribute of the descending carrier corresponding with CSI report Or the order successively decreased, the CSI report in this CSI reported is ranked up, the attribute bag of descending carrier Include descending carrier index.The present invention preferably successively decreases according to the carrier index of descending carrier corresponding to CSI report Order, the CSI report in this CSI reported is ranked up.

Should also be understood that when the CSI reported finally determined when subscriber equipment only includes a CSI report, Need not be ranked up CSI report, i.e. flow process is directly from S210 to S230, and now S230 is the most right Information bit sequence corresponding to this CSI report carries out chnnel coding.When subscriber equipment is in step S230 When using independent channel coding, step S220 can also need not, and i.e. flow process is directly from S210 to S230.

In S230, the subscriber equipment CSI to reporting carries out chnnel coding, obtains CSI and encodes information. Wherein, the subscriber equipment CSI to reporting carries out chnnel coding and can carry out by one of the following two kinds mode:

Mode one: the CSI reported is carried out combined channel coding.

In embodiments of the present invention, the CSI reported is entered by subscriber equipment to the feelings of combined channel coding Condition, the actual CSI information bit sequence for obtaining step S220 is entered combined channel coding, is specifically wrapped Include: the total information bit number of K CSI report of the reporting status information of channel determined when subscriber equipment During less than or equal to 11 bit, Randt's Miller RM (Reed-Muller) (32, O) code is used to carry out Coding；When the total information bit number of this K CSI report is more than 11 bit, use double Randt's Miller RM (Reed-Muller) (32, O) code encodes.Should be understood that the embodiment of the present invention is double to use Randt's Miller RM code illustrates as a example by carrying out chnnel coding, but the embodiment of the present invention is not limited to this, Such as can also use tail-biting convolutional code (Tail Biting Convolutional Code, referred to as " TBCC ") Carry out chnnel coding.

When utilizing double Randt's Miller RM (32, O) code, K the channel status information reports reported is entered During row chnnel coding, subscriber equipment carries out chnnel coding to this CSI information bit sequence and may include that

The total information bit of K channel status information reports is divided into two parts by subscriber equipment.Specifically, If this total information bit number is even number, then this total information bit is divided into information bit equal by subscriber equipment Two parts；If this total information bit number is odd number, then at subscriber equipment, this total information bit is divided into In two parts information bit, the information bit of Part II 1 ratio fewer than the information bit of Part I Special；

Subscriber equipment utilizes RM (32, O) code to encode the information bit that every part is corresponding；

Alternately from two parts coded information bits, choose coded-bit with Qm bit for granularity, obtain One new sequences of code bits, wherein Qm is the modulation system of CSI report, for example, quaternary phase shift Keying (Quadrature Phase Shift Keying, referred to as " QPSK ") modulation system.

If " upper according to CSI report of subscriber equipment that in S220, the sort method of K CSI report is The order that the priority of report type is incremented by, is ranked up the CSI report in this CSI reported, if The priority of the reporting types of CSI report is identical, then according to the carrier wave of descending carrier corresponding to CSI report The order successively decreased of index is ranked up ", then due in S230, if the channel shape of X descending carrier When the total information bit number of state information report is odd number, the information bit of Part II is than Part I Few 1 bit of information bit, now can make the CSI report of the reporting types that priority is higher be in Containing the part of less information bit, and coded method corresponding to the two partial information bit and money Source is consistent, thus can improve the performance of the CSI report of the higher reporting types of priority, thus protects as far as possible The performance of the CSI report that card target performance requirement is high.

It should be noted that the rule in S220 being ranked up CSI report can also be: subscriber equipment According to the order of the decreasing priority of the reporting types of CSI report, the CSI of this X descending carrier is reported Announcement is ranked up, if reporting types is identical, the order being incremented by according to the carrier index of descending carrier is arranged Sequence；But now in S230, in two parts information bit that total information bit is divided into by subscriber equipment, The information bit that Part I is corresponding needs few 1 bit of the information bit more corresponding than Part II, The performance of the CSI report of the higher reporting types of priority can be improved, thus ensure that target capabilities is wanted as far as possible Seek the performance of high CSI report.

Mode two: to the CSI report belonging to the first reporting source of channel state information type in the CSI reported Independent channel coding is carried out with the CSI report belonging to second channel state information report type.

In embodiments of the present invention under which, if the reporting types of K CSI report broadly falls into first CSI reporting types or broadly fall into the 2nd CSI reporting types, then combine letter to this K CSI report Road encodes, and the CSI information bit sequence i.e. obtained step S220 carries out combined channel coding；If K In individual CSI report, the reporting types of X1 (X1 is positive integer and X1 ＜ K) individual CSI report belongs to One CSI reporting types, the reporting types of X2 (X2 is positive integer and X2 ＜ X) individual CSI report belongs to 2nd CSI reporting types, then carry out independent channel volume to X1 CSI report and X2 CSI report Code, and before carrying out independent channel coding, can be the most respectively to X1 CSI report and X2 CSI report It is ranked up, respectively obtains the first CSI report information bit sequence and the second CSI report information bit sequence Row, sort method can be that the carrier index of the descending carrier corresponding according to CSI report is successively decreased or incremental suitable Sequence is ranked up.

Alternatively, to the CSI report belonging to the first reporting source of channel state information type in the CSI reported Independent channel coding is carried out with the CSI report belonging to second channel state information report type, including:

At least one first CSI report respectively this CSI reported included and at least one the 2nd CSI Report carries out chnnel coding, obtains this CSI and encodes information, and the reporting types of this first CSI report belongs to Oneth CSI reporting types, the reporting types of this second CSI report belongs to the 2nd CSI reporting types, should The performance requirement of the oneth CSI reporting types is higher than the performance requirement of the 2nd CSI reporting types.

Alternatively, this at least one first CSI report and at least one respectively this CSI reported included Individual second CSI report carries out chnnel coding, including:

It is respectively this at least one first CSI report and this at least one second CSI report distribution first volume Code bit number and the second number of coded bits, this first number of coded bits is more than this second number of coded bits；

Respectively according to this first number of coded bits and this second number of coded bits, to this at least one first CSI report and this at least one second CSI report carry out chnnel coding.

Specifically, subscriber equipment is utilized respectively RM (32, O) code, to by under the X1 after sorting The first CSI report information bit sequence sequence that the CSI report of row carrier wave is formed, and by sorting after The second CSI report information bit sequence sequence that the CSI report of X2 descending carrier is formed is carried out respectively Number of coded bits that the CSI report of X1 descending carrier after chnnel coding, and sequence is corresponding and sequence After number of coded bits corresponding to the CSI report of X2 descending carrier differ, be specifically as follows sequence After chnnel coding corresponding to the CSI report of X1 descending carrier after bit number, after sequence Bit number after the chnnel coding that the CSI report of X2 descending carrier is corresponding.

Such as, RM (32, the O) code channel status to X1 descending carrier after sequence it is utilized respectively After the channel status information reports of information report and X2 descending carrier carries out chnnel coding, and sequence Bit number after the chnnel coding that the channel status information reports of X1 descending carrier is corresponding isThe channel status information reports pair of X2 descending carrier after sequence Bit number after the chnnel coding answered is Wherein, Q_mFor modulation Coded system, For the total information bit number of CSI report corresponding with X2 descending carrier for X1, For the total information bit number of the CSI report of X1 descending carrier, β_offsetThe value notified for high-level signaling, It can be such as the value of the semi-static notice of high-level signaling.

In this step, channel status information reports and X2 the descending carrier to X1 descending carrier Channel status information reports carry out absolute coding, and the channel status information reports of X1 descending carrier Corresponding more coded-bit, is equivalent to give more resource the channel status of X1 descending carrier Information is reported, thus improves the performance of the channel status information reports of X1 descending carrier, it is ensured that The channel condition information of X1 descending carrier.Alternatively, it is also possible to by the channel of X1 descending carrier The coded-bit that status information reporting is different with the distribution of the channel status information reports of X2 descending carrier Method so that the channel status information reports of X1 descending carrier reaches the signal to noise ratio that performance objective requires The signal to noise ratio that performance objective requires is reached identical with the channel status information reports of X2 descending carrier, from And the performance requirement raising avoiding the occurrence of the channel status information reports because of X1 descending carrier to be met is sent out Penetrate power, and this transmitting power performance requirement to the channel status information reports of X2 descending carrier For superfluous problem, it is possible to put forward high-power utilization ratio.

It should be noted that the channel status information reports to X descending carrier carries out independence in this step The method of chnnel coding can be also used for other scene, such as, send letter on PUCCH channel when needs When channel state information CSI report and mixed automatic retransfer confirmation ACK/NACK, due to The performance objective of ACK/NACK requires the performance objective requirement higher than CSI report, thus itself and this step In rapid, the performance objective of the channel status information reports of X1 descending carrier requires higher than X2 descending load The situation of the channel status information reports of ripple is similar to, thus the side that the independent channel in this step can be encoded The situation that method is applied to CSI report and ACK/NACK transmits simultaneously, concrete grammar is retouched with this step State similar, only need to the channel status information reports of X1 descending carrier in this step be changed into be transmitted ACK/NACK, the channel status information reports of X2 descending carrier in this step is changed into be passed Defeated CSI report, concrete mechanism repeats no more.

In S240, this CSI coding information is modulated by subscriber equipment, obtains CSI modulation symbol.

In S250, this CSI modulation symbol is mapped on this physical uplink channel concurrently by subscriber equipment Give this base station.
