101, UE is at parameter information and the RSN of S-E-DPCCH to base station transmission E-TFCI, and wherein, the parameter information of this E-TFCI is used to obtain the auxilliary E-TFCI that flows by the base station, and the E-TFCI of auxilliary stream and RSN are used to receive upward data carried by data of S-E-DPDCH by the base station.

The application scenarios of present embodiment is in the UL mimo system, on E-DPDCH, carries and send main flow, carries and send the main flow control information corresponding at E-DPCCH.And on the new S-E-DPDCH that introduces, carry and the auxilliary stream of transmission; Carry and send auxilliary stream control information corresponding at S-E-DPCCH; Parameter information and RSN like the E-TFCI in the present embodiment; Obtain the E-TFCI of auxilliary stream for the base station according to the parameter information of E-TFCI, and accurately receive S-E-DPDCH according to the E-TFCI of auxilliary stream with RSN and go up data carried by data, thereby can guarantee effectively that the base station can accurately receive the auxilliary flow data of S-E-DPDCH transmission.

The transmission method of the control information of present embodiment, UE be through carrying parameter information and the RSN of E-TFCI on S-E-DPCCH, the parameter information of E-TFCI and RSN be with the corresponding S-E-DPDCH of S-E-DPCCH on the relevant control information of transmission data of carrying; And at parameter information and the RSN of S-E-DPCCH to base station transmission E-TFCI, wherein the parameter information of E-TFCI is used to obtain the auxilliary E-TFCI that flows by the base station, and the E-TFCI of auxilliary stream and RSN are used to receive upward data carried by data of S-E-DPDCH by the base station.The technical scheme of present embodiment; Can remedy the deficiency of the transmission means that lacks the control information in the UL MIMO technology in the prior art; A kind of transmission plan of control information efficiently can be provided, thereby guarantee transmission of uplink data in the UL mimo system effectively.

On above-mentioned basis embodiment illustrated in fig. 2, can also comprise following optional technical scheme, constitute optional embodiment embodiment illustrated in fig. 2.

In optional embodiment embodiment illustrated in fig. 2, the parameter information of E-TFCI specifically can comprise following several kinds of situation:

The parameter information of first kind of situation: E-TFCI is the E-TFCI of auxilliary stream.The required bit number of the E-TFCI of auxilliary stream and the E-TFCI of main flow is identical, all is k bit, 0＜k＜=7.

The parameter information of second kind of situation: E-TFCI is the side-play amount of the E-TFCI of auxilliary stream with respect to the E-TFCI of main flow;

Under the prerequisite of main flow channel quality more than or equal to auxilliary stream channel quality, the inevitable E-TFCI of the E-TFCI of auxilliary stream smaller or equal to main flow, then the E-TFCI of auxilliary stream is 0～-2 with respect to the side-play amount of the E-TFCI of main flow ^k-1.Conversely, under the prerequisite of main flow channel quality less than auxilliary stream channel quality, the E-TFCI of auxilliary stream is greater than the E-TFCI of main flow, and then the E-TFCI of auxilliary stream is-2 with respect to the side-play amount of the E-TFCI of main flow ^k-1～0.In double-stream mode; In the corresponding E-DPCCH of main flow, carried and sent the E-TFCI of main flow; Corresponding S-E-DPCCH carries and sends the side-play amount of the E-TFCI of auxilliary stream with respect to the E-TFCI of main flow at auxilliary stream; The base station can calculate the E-TFCI of auxilliary stream according to E-TFCI that receives main flow and the side-play amount of the auxilliary E-TFCI that flows with respect to the E-TFCI of main flow.In like manner under this second kind of situation, the E-TFCI of auxilliary stream also need take k bit with respect to the side-play amount of the E-TFCI of main flow and carry 0＜k＜=7.

The parameter information of the third situation: E-TFCI is the E-TFCI of the auxilliary stream index sign corresponding with respect to the side-play amount of the E-TFCI of main flow; It is the auxilliary stream E-TFCI Domain Index number in the present embodiment.

If the parameter information of E-TFCI adopts above-mentioned first kind of situation and second kind of situation, the last parameter information that needs the E-TFCI of carrying k bit of S-E-DPCCH.In order to save the bit number of the parameter information that is used to carry E-TFCI on the S-E-DPCCH effectively, can be 0 as an interval with respect to the side-play amount of the E-TFCI of main flow with the E-TFCI that assists stream in the embodiment of the invention, be called first interval.The auxilliary E-TFCI that flows is divided between several region with respect to other side-play amounts of the E-TFCI of main flow as far as possible, and each interval is divided into n side-play amount, and n is more than or equal to 1.And get the included side-play amount maximum in this interval as this interval side-play amount, the side-play amount that last interval comprises can less than other etc. the side-play amount of by stages.For example get k=7 in the present embodiment; N=4; Is that the situation of positive number is that example is explained with the E-TFCI of auxilliary stream with respect to the side-play amount of the E-TFCI of main flow; The corresponding relation of side-play amount as shown in table 4, interval side-play amount and corresponding call number, the E-TFCI that can know the auxilliary stream that first is interval is 0 with respect to the side-play amount of the E-TFCI of main flow, promptly interval side-play amount is 0.The the 2nd to the 30th interval, each interval comprises 4 side-play amounts, interval accordingly side-play amount is the 4th side-play amount in this interval, is that 4, the 3 intervals are that 8, the 4 intervals are 12 or the like like the 2nd interval.The 32nd interval only comprises 7 side-play amounts (being between the side-play amount 120-127), and corresponding interval side-play amount is 127.Then each interval being provided with that an auxilliary stream E-TFCI Domain Index number identifies should the interval, and totally 32 intervals can adopt 5 bits to represent call number like this, and corresponding each call number can obtain corresponding interval side-play amount.

Table 4

Above-mentioned table 4 is to be that the situation of positive number is an example with the E-TFCI of auxilliary stream with respect to the side-play amount of the E-TFCI of main flow; In the practical application; The E-TFCI of auxilliary stream is a positive number with respect to the side-play amount of the E-TFCI of main flow; When the E-TFCI of auxilliary stream was negative with respect to the side-play amount of the E-TFCI of main flow, situation was similar, repeats no more at this.Be with k=7 in the foregoing description, n=4 is the technical scheme that example is described the embodiment of the invention, and in the practical application, k and n also can get other integers, 0＜n＜=k＜=7.

By the relation of above-mentioned table 4, the corresponding call number of side-play amount between can supporting region on the S-E-DPCCH, and send to the base station; Number get access to corresponding interval side-play amount according to auxilliary stream E-TFCI Domain Index like this; Go up the interval side-play amount that the corresponding call number of interval side-play amount of carrying is obtained correspondence according to S-E-DPCCH again, and then go up the E-TFCI of the main flow that receives and the E-TFCI that interval side-play amount is obtained auxilliary stream correspondence according to E-DPCCH.

Adopt the scheme of above-mentioned the third situation, when n gets 4, only need k-2bit to carry the parameter information of E-TFCI, for first kind of situation and second kind of situation, can reduce the carrying bit number on the S-E-DPCCH, improve efficiency of transmission.

In the such scheme, except first interval and last interval, each number of the side-play amount that comprises in each interval between other mesozones equates.In the practical application, the side-play amount number that comprises in each interval between other mesozones can be unequal, and for example in the less section of side-play amount, the side-play amount number in every interval is less, and the side-play amount number in the bigger section of side-play amount in every interval is more.For each interval, still get the interval side-play amount of this interval side-play amount maximum as this interval.For example total interval number is O; Promptly corresponding call number is O; Then shared log2 (O) bit carries the parameter information of E-TFCI, because interval number is less than the number of side-play amount, therefore with respect to above-mentioned first kind of situation and second kind of situation; Can reduce the carrying bit number on the S-E-DPCCH, improve efficiency of transmission.

The index that the E-TFCI of the auxilliary stream of the parameter information of the 4th kind of situation: E-TFCI is corresponding with the ratio of the E-TFCI of main flow identifies, i.e. auxilliary stream E-TFCI Domain Index in the present embodiment number.

Under the prerequisite of main flow channel quality more than or equal to auxilliary stream channel quality; The inevitable E-TFCI of the E-TFCI of auxilliary stream smaller or equal to main flow; Promptly the inevitable TBS smaller or equal to main flow of the TBS of auxilliary stream size is big or small, and then the TBS size of auxilliary stream must be to be the number between 0～1 with respect to the TBS magnitude proportion of main flow.The ratio of E-TFCI of representing E-TFCI and the main flow of this auxilliary stream with the p bit, promptly 1/2 ^p～1, as shown in table 5.The auxilliary stream TBS size of go up carrying according to S-E-DPCCH adds that with respect to main flow TBS magnitude proportion E-DPCCH goes up the E-TFCI value of the main flow of carrying, and just can obtain assisting the TBS size that flows is the maximum TBS piece less than floor (the big or small * ratio value of main flow TBS).

Table 5

For example: the E-TFCI Domain Index that solves main flow according to E-DPCCH number is 65, and promptly the corresponding TBS of mainstream data is 1217; And the E-TFCI Domain Index of auxilliary stream number is 4, p=5, and the TBS size that can obtain auxilliary stream according to table is with respect to main flow TBS magnitude proportion

Promptly the TBS size of auxilliary stream does $(\mathrm{Floor}(217\×\frac{5}{32})=190),$ Obtaining the corresponding TBS of auxilliary flow data according to table again is 185.

Conversely, under the prerequisite of main flow channel quality less than auxilliary stream channel quality, can adopt the E-TFCI and the ratio of assisting the E-TFCI that flows of the parameter information main flow of E-TFCI, other can repeat no more at this with reference to the technical scheme of the foregoing description.

And adopt the scheme of above-mentioned the 4th kind of situation, for first kind of situation and second kind of situation, this scheme can reduce the carrying bit number on the S-E-DPCCH, improves efficiency of transmission.

Further alternatively, in optional embodiment embodiment illustrated in fig. 2, can also comprise the steps:

(1) UE also carries the satisfaction identification information on S-DPCCH or S-E-DPCCH;

(2) UE sends the satisfaction identification information to the base station on S-DPCCH or S-E-DPCCH, and this satisfaction identification information is used for confirming by the base station whether UE is satisfied with to total License Value of this data transfer of base station assigns.

The restriction that step 100 in this step (1) and (2) and the foregoing description and step 101 can not have sequencing.

Satisfaction identification information in the present embodiment specifically can be " Happy " bit that puts down in writing in the foregoing description; And the definition of " Happy " bit should to be UE give this data transfer (corresponding single current during single-stream mode for base station assigns; Comprise main flow and auxilliary stream during double-stream mode) total License Value whether be satisfied with, so not necessarily need issue this " Happy " bit separately to auxilliary stream.Therefore present embodiment proposes on S-DPCCH, to carry " Happy " bit, and " Happy " bit that can cancel on the E-DPCCH this moment issues, and " Happy " bit that also can keep on the E-DPCCH issues.The position of " Happy " bit in S-DPCCH can change the fixed territory among the S-DPCCH in the UL-CLTD system into " Happy " bit territory, perhaps also can in the S-DPCCH in the UL-CLTD system, increase 1 bit newly and carry " Happy " bit.Through on S-DPCCH, sending " Happy " bit; Just can other territory be changed in " Happy " bit territory among the original E-DPCCH,, be used for sending other control informations like Rank territory or PPI territory; Guarantee the integrality of UL-MIMO control information transmission, improved the reception correctness of base station.

Further alternatively, in optional embodiment embodiment illustrated in fig. 2, can also comprise the steps:

(a) UE carries the number of data streams identification information on S-DPCCH, E-DPCCH or S-E-DPCCH;

(b) UE sends the number of data streams identification information to the base station on S-DPCCH, E-DPCCH or S-E-DPCCH, and this number of data streams identification information is used for confirming that by the base station UE data flow transmitted is single current or double fluid.

This step (i) and (ii) with the foregoing description in the restriction that can not have sequencing of step 100 and step 101.

For example when stream transmission, process identification (PID) is used to indicate main flow or auxilliary stream to go up the corresponding concurrent process of data block transmitted number; When single-stream transmission, process identification (PID) is used to indicate the corresponding process number of the data block of single-stream transmission or is used to indicate the not corresponding process number of data block transmitted of single current.Further; Because concurrent process only has two, i.e. No. 0 process and No. 1 process are when stream transmission; If process identification (PID) is used to indicate the corresponding concurrent process of data block transmitted on the main flow number, then auxilliary stream to go up inevitable corresponding another concurrent process of data block transmitted number; If process identification (PID) is used to indicate auxilliary stream to go up the corresponding concurrent process of data block transmitted number, inevitable corresponding another concurrent process of data block transmitted number on the main flow then; If the major-minor journey sign that flows to is sent simultaneously, then can directly obtain.Promptly when stream transmission, can simultaneously on E-DPCCH and S-DPCCH, perhaps on E-DPCCH and S-E-DPCCH, send process identification (PID) simultaneously, to represent on E-DPDCH and S-E-DPDCH, carrying the corresponding process of data respectively with the district.Process identification (PID) encoding scheme like below table 7 is an example.Can the fixed territory among the S-DPCCH in the UL-CLTD system be changed into concurrent process indication (Parallel Process Indicator like this; PPI) territory, to carry process identification (PID), this moment, corresponding process was 0 00 of concurrent process, was 1 11 of concurrent process.Perhaps can change the Rank territory into through " Happy " bit territory on the E-DPCCH, to carry Rank information, this moment, corresponding process was 00 of concurrent process, was 11 of concurrent process.Perhaps can also on S-E-DPCCH, increase the PPI territory to carry process identification (PID), what this moment was corresponding can increase x bit, for example adopts No. 1 process of x 1 expression, adopts No. 0 process of x 0 expression.

Table 7

		Concurrent process 0	0
Concurrent process 1	1

Because the up employing of UMTS is synchronized process,, only just can confirm current process according to subframe numbers (or radio frame number) so in original HARQ information, do not have the information of process number.And in the UL mimo system, each TTI has two concurrent processes at most, if there is not indication information, may obscure when retransmitting again.Therefore can introduce concurrent process indication PPI to indicate current process identification (PID), in order to distinguish two concurrent processes that possibly occur under the UL-MIMO system.
