CQI comprises recommendation modulation system (Recommended Modulation Format, RMF) and recommends transmission block size (Recommended Transport Block Size, RTBS).
As shown in Figure 1, be the structure of HS-SICH channel of the prior art and the schematic diagram of decoding scheme.
ACK/NACK is the feedback information for supporting HARQ (Hybrid Automatic Repeat request, mixed automatic retransfer request).Information bit is 1bit.
Can learn from the result of emulation, the importance of ACK/NACK bit is very high, if made a mistake very large to systematic influence.Like this, ACK/NACK need to have the coding that reliability is very high to ensure its performance.The scheme adopting is the method for repeated encoding.
CQI is another very important feedback information, is used to indicate current channel quality.Channel estimating is at UE (User Equipment, subscriber equipment) side completes, can be by measuring P-CCPCH (PrimaryCommon Control Physical Channel, Primary Common Control Physical Channel) RSCP (ReceivedSignal Code Power, received signal code power)/ISCP (Interference Signal Code Power, Interference Signal Code Power) carry out channel estimating. according to estimated result, UE is according to known HS-PDSCH (High Speed Physical Downlink Shared Channel, high-speed physical downlink shared channel (HS-PDSCH)) resource allocation status chooses suitable CQI and feeds back.CQI needs very high reliability equally, because NodeB (Node B, i.e. base station) determines the transformat sending according to CQI next time.The coding of CQI can be respectively RTBS and RMP.
RTBS adopts the R-M coding of similar TFCI (Transport Format Combination Indicator, transport format combination identifiers), and RMF can adopt simple repeated encoding to complete.
In general, HS-SICH is mapped to TSI, and adopts 16 spreading factor.
HS-SICH also needs to keep uplink synchronous.HS-SICH initial timing comes from up DPCH (Dedicated Physical Channel, DPCH), and synchronous maintains according to the SS order on HS-SCCH, and step-length comes from high level.But do not receive HS-SCCH transmission time because UE has, now, the reception of SS order comes from the descending DPCH following, until receiving HS-SCCH, UE transmits.The definite timing relationship of HS-DSCH and HS-S1CH is decided by high level.

Different from existing technical scheme, HS-SCCH information dropout mark, has taken HS-SICH information Central Plains and has been useful on the resource of transmitting RMF information.
Compared with prior art, the embodiment of the present invention has the following advantages:
By the technical scheme of the application embodiment of the present invention, in the HS-SICH information of terminal equipment feedback, remove recommendation modulation system (RMF) information, increase HS-SCCH information dropout mark.The recommendation transmission block size (RTBS) that base station only reports according to terminal equipment just can be judged channel quality, so, can save the feedback of recommending modulation system, and the HS-SCCH information dropout increasing mark can make base station judge accurately the error probability of HS-SICH and HS-SCCH, thereby, the power control that base station can be optimized according to the statistics of corresponding error probability accurately.
Below, in conjunction with concrete application scenarios, the technical scheme that the embodiment of the present invention is proposed describes.
In order to realize the goal of the invention of the embodiment of the present invention, UE, in the time sending HS-SICH information, adopts the encoding scheme of optimizing, and removes original 1 bit RMF information, and use 1 bit HS-SCCH Information sign position to replace, in this flag bit, carry HS-SCCH information dropout mark.
The feasibility of processing is like this because base station side will be calculated the code check that UE recommends, as long as know that the RTBS information of UE side feedback is just passable, RMF information is not generally used.
As shown in Figure 4, the structure of HS-SICH and the schematic diagram of encoding scheme after the improvement proposing for the embodiment of the present invention.
Wherein, the implication of HS-SCCH Information sign position is: for making base station can judge accordingly the loss situation of UE side HS-SCCH information, UE often detects and loses a HS-SCCH, just will send to the information in the HS-SCCH Information sign position of a HS-SICH information of base station to be set to " 1 ", otherwise the information in the HS-SCCH Information sign position of HS-SICH information is set to " 0 " by UE.
For example: UE finds undetected 2 HS-SCCH (can judge by the HCSN territory of HS-SCCH), so, UE will send to the information in the HS-SCCH Information sign position of follow-up 2 HS-SICH information of base station to be set to " 1 ", make in this period of time, the number that the entrained information of HS-SICH information that UE sends to base station is set to the HS-SCCH flag bit of " 1 " equals UE does not separate the number of right HS-SCCH information.
Base station side receives after such HS-SICH information, can get according to the information number that is set to " 1 " in HS-SCCH flag bit the HS-SCCH information reception condition of UE side, and and then determine and issue the error probability of HS-SCCH, thereby, carry out the adjustment of power control strategy.
In order to determine relevant information, concrete processing procedure is as follows:
First, suppose that information in HS-SCCH flag bit that the Loss Rate Y=base station end of HS-SCCH information receives is set to the HS-SCCH number that the number/base station of " 1 " sends, like this, Y can obtain from base station end statistics.
Wherein, the information in the HS-SCCH flag bit that base station end is received is set to the number of " 1 ", is aforesaid terminal equipment and detects the quantity of the mark of HS-SCCH information dropout, so this parameter represents with L, above-mentioned formula can be abbreviated as:
Y＝L/N (1)
Then, set in HS-SICH and indicate that the probability of bit-errors is B.
Suppose within a period of time, N HS-SCCH information has been sent out in base station, and wherein have M UE not receive, so, UE will be to base station feedback N-M HS-SICH information, wherein, the information in the entrained HS-SCCH Information sign position of M HS-SICH information is that the information in the entrained HS-SCCH Information sign position of " 1 ", a N-2M HS-SICH information is " 0 ".
Suppose that base station side does not activate detection (judgement that signal has or not), is fixed decoding, the number of the HS-SICH that the flag bit of receiving is " 1 " is:
L＝M(1-B)+(N-2M)B+0.5M＝1.5M-3MB+NB (2)
Wherein, suppose in the time that UE does not send out HS-SICH, when the fixed test of base station, the probability that is " 1 " for " 0 " and empty inspection by empty flag bit inspection is identical, respectively account for 1/2.
, according to the definition of Y, by formula (2) substitution formula (1), obtain shifting result onto as follows:
Y＝L/N＝(1.5M-3MB+NB)/N
＝(1.5-3B)*(M/N)+B＝(1.5-3B)X+B (3)
Wherein, establish X=M/N, be the reception error probability of the HS-SCCH of UE side, by (3):
X＝(Y-B)/(1.5-3*B) (4)
Wherein, 3*B relative 1.5 is very little amounts, so it is as follows that above-mentioned formula (4) can be similar to simplification:
X＝(Y-B)/1.5 (5)
Can determine C by the soft bit of ACK/NACK and flag bit at receiving terminal (base station side), and there is following relation of equal quantity in C:
C＝X+B (6)
The method of measurement of the similar and existing HS-SICH channel quality of reception of definite method of above-mentioned relation of equal quantity.
Like this, based on above-mentioned each formula, just can solve the error probability B of HS-SICH, and the error probability X of HS-SCCH:
X＝2Y-2C (7)
B＝3C-2Y (8)
The coding flow process of HS-SICH in the embodiment of the present invention can be consistent with existing TS25.222 agreement, also can adopt novel coded system, such as RA code, further improves performance.
The formula obtaining by above-mentioned derivation, base station side can obtain the error probability of HS-SICH and the error probability of HS-SCCH, thus base station can better be dispatched and the relevant treatment such as RRM.
