As shown in Figure 1, be the structure of HS-SICH channel of the prior art and the sketch map of decoding scheme.
ACK/NACK is used to support the HARQ feedback information of (Hybrid Automatic Repeat request mixes automatic repeat requests).Information bit is 1bit.
Can learn that from the result of emulation the importance of ACK/NACK bit is very high, if make a mistake with very big to systematic influence.Like this, ACK/NACK needs the very high coding of reliability and guarantees its performance.The scheme that adopts 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 is accomplished; Can be through measuring P-CCPCH (Primary Common Control Physical Channel; Primary Common Control Physical Channel) RSCP (Received Signal Code Power, received signal code power)/ISCP (Interference Signal Code Power, Interference Signal Code Power) carries out channel estimating. according to estimated result; UE chooses appropriate C QI and feeds back according to known HS-PDSCH (High Speed Physical Downlink Shared Channel, high-speed physical downlink shared channel (HS-PDSCH)) resource allocation status.CQI needs very high reliability equally, because NodeB (Node B, the i.e. base station) transformat that decision is sent according to CQI next time.The coding of CQI can be respectively RTBS and RMP.

In concrete application scenarios, the size of the HS-SCCH information dropout sign that HS-SICH information is comprised is specially 1 bit.
Different with existing technical scheme is that HS-SCCH information dropout sign 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 invention has the following advantages:
Through using the technical scheme of the embodiment of the invention, in the HS-SICH information of terminal equipment feedback, removed recommendation modulation system (RMF) information, increased HS-SCCH information dropout sign.Channel quality only just can be judged according to the recommendation transmission block size (RTBS) that terminal equipment reports in the base station; So; Can save the feedback of recommending modulation system; And the HS-SCCH information dropout that increases sign can make the base station judge the error probability of HS-SICH and HS-SCCH accurately, thereby, the power control that the base station can be optimized according to corresponding error probability statistical result accurately.
Below, the application scenarios in conjunction with concrete describes the technical scheme that the embodiment of the invention proposed.
In order to realize the goal of the invention of the embodiment of the invention; UE adopts the encoding scheme of optimizing when sending HS-SICH information, remove original 1 bit RMF information; And use 1 bit HS-SCCH Information sign position to replace, carry HS-SCCH information dropout sign in this flag bit.
The feasibility of handling like this is 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 generally is not used.
As shown in Figure 4, be the sketch map of structure and the encoding scheme of the HS-SICH after the improvement that the embodiment of the invention proposed.
Wherein, The implication of HS-SCCH Information sign position is: be used to make the base station can judge the loss situation of UE side HS-SCCH information in view of the above; UE whenever detects and loses a HS-SCCH; The information that just will send in the HS-SCCH Information sign position of a HS-SICH information of base station is changed to " 1 ", otherwise UE is changed to " 0 " with the information in the HS-SCCH Information sign position of HS-SICH information.
For example: UE has found omission 2 HS-SCCH (can judge) through the HCSN territory of HS-SCCH; So; The information that UE will send in the HS-SCCH Information sign position of follow-up 2 HS-SICH information of base station is changed to " 1 "; Make this section in the period, the number that the entrained information of HS-SICH information that UE sends to the base station is changed to the HS-SCCH flag bit of " 1 " equals the number that UE does not separate right HS-SCCH information.
After base station side receives such HS-SICH information; Can get access to the HS-SCCH information reception condition of UE side according to the information number that is changed to " 1 " in the HS-SCCH flag bit; And and then confirm to issue the error probability of HS-SCCH, thereby, carry out the adjustment of power control strategy.
In order to confirm relevant information, concrete processing procedure is following:
At first, suppose that information in the HS-SCCH flag bit that the Loss Rate Y=base station end of HS-SCCH information receives is changed to the HS-SCCH number that send the number/base station of " 1 ", like this, Y can obtain from the base station end statistics.
Wherein, the information in the HS-SCCH flag bit that base station end is received is changed to the number of " 1 ", is the quantity that aforesaid terminal equipment detects the sign of HS-SCCH information dropout, so this parameter representes that with L above-mentioned formula can be abbreviated as:
Y＝L/N (1)
Then, setting the probability that indicates bit-errors among the HS-SICH is B.
Suppose in a period of time; N HS-SCCH information has been sent out in the 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), fixes decoding, the flag bit of then receiving for the number of the HS-SICH of " 1 " is:
L＝M(1-B)+(N-2M)B+0.5M＝1.5M-3MB+NB (2)
Wherein, suppose when UE does not send out HS-SICH that during the fixed test of base station, the probability that is " 1 " for " 0 " and empty inspection with the empty inspection of flag bit is identical, respectively account for 1/2.
Then according to the definition of Y, in formula (2) substitution formula (1), it is following to obtain shifting the result onto:
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, then by (3):
X＝(Y-B)/(1.5-3*B) (4)
Wherein, 3*B relative 1.5 is very little amounts, so above-mentioned formula (4) can be similar to be simplified as follows:
X＝(Y-B)/1.5 (5)
Can confirm C through 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 of the definite method quality of reception of above-mentioned relation of equal quantity.
Like this,, just can solve the error probability B of HS-SICH based on each above-mentioned formula, 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 invention can be consistent with existing TS25.222 agreement, also can adopt novel coded system, such as the RA sign indicating number, comes further to improve performance.
Through the resulting formula of above-mentioned derivation, base station side can obtain the error probability of HS-SICH and the error probability of HS-SCCH, thereby the base station can better be dispatched and relevant treatment such as RRM.
