Abstract

The present invention discloses a method, device and system for self-adaptive retransmission. In the scheme of the present invention, a base station determines the transmitting mode of the next transmission and the data to be transmitted according to the result that the user equipment processes the current double code stream data and the downlink quality information which is measured and reported by the user equipment. According to the current downlink status effectively, for the code stream with transmission error, the application of the scheme for self-adaptively selecting the transmitting mode of the retransmission enables flexibly selecting the optimum retransmission multiple antennas transmitting mode from the double code stream multiplex mode, the diversity transmitting mode and single code stream multiplex mode, and obtaining the gains which contains retransmission gain. The application of the present invention can save the system resource and improve the transmission success rates by using the real time change of the channel sufficiently, thereby improving the whole performance of the system.

1 The method of this method is shown in

2 The flow chart of the method used in this book is shown in the figure 3

4 The indication of the device in this book

5 Li Benming, the general gesture of this. Hugh way

In the present specification, the user's various conditions and the downlink health information of each user's measurement determine the number of shots and the number of next shots.

The means and function of the purpose of the purpose The method, device and system described herein are described in detail below.

This paragraph, shown in Figure 1, this method includes the following steps

Step 101: Take the user's situation, and include

Sent to the user, each received by the user

If the user is not able to respond to the AC information user, the AC information will be reversed. Step 102: The user measures the uplink and downlink information, and the downlink information includes a carrier ratio, a matrix, and an index of the coding matrix.

Since in the existing wood, the measurement of the above-mentioned downlink information is a function that the user already has, the user's respective measurement is no longer available.

Step 103: AC information of the user's various mediations, number of re-AC information, and comparison of the phase of the in-phase letter matrix

The matrix is greater than 1 , indicating that the same phase is weak, you can use the way sheep, special step 104

If the matrix is equal to 1 , it means that the same phase is stronger. In particular, step 105 needs to explain that the AC information of the user's opposites indicates that the downlink is very good, and the user has not yet appeared.

The AC information indicates that the downside is not good. The above-mentioned God situation is still in accordance with the existing practice in the wood, that is, the multi-day shooting method is not changed, and the same multi-day shooting method is used last time.

Step 104, the carrier ratio is used In the case of the rest, the carrier ratio is obtained by the gain of the carrier on each user, as shown in 2, and the following steps are included.

Step 201: respectively determine a different CS (od a o a d Cod gSche e, and encoding method)

, the ratio of the carrier ratio of the solid S R S R ax, of, 10%

In step 202, if the carrier ratio is greater than SR and the upper gain is obtained, if the carrier ratio is greater than SR, then in step 203, if the carrier ratio is not greater than SR, then the carrier ratio of the special step 204 is greater than SR, The CS and mode are those that can meet the communication requirements. The carrier ratio is not greater than SR. If the previous CS and mode cannot meet the communication requirements, the lower the CS, CS, the lower the required ratio.

In step 203, the carrier ratio is greater than S R , indicating that the downlink is better and can be higher or larger, so it can be any of the following modes.

The first and the new ones, that is, the new ones

The second will reduce the original RB (Resources, Re o ce Boc), CS does not, and mediation.

Step 204: The carrier ratio is not greater than S R , indicating that the downlink is poor, and the RB is not and the CS is lowered.

of. Step 105: The most recent segment is shown by index 3 of the precoding matrix on each user, and includes

In step 301, the value of the reception in , the value of , can be equal to the multiple of TT (Ta o T e eva, the same). The TT can be the same, or the sub-multiple, the different requirements, and the recent paragraphs are the same.

Step 302: The index of the precoding matrix on each user in the pre-receiving window sent by the user, whether the index of the coding matrix is normalized, and if yes, the information is in the case of a special condition, and the special step 303 otherwise indicates that the information is not the case. Special step 304

Step 303, the way sheep.

Step 304, sheep way sheep.

In the following, we have the ability to take the rest of the way.

Send to users

Analyze the user's reverse ACK/AC information, and the parsed information is new.

The former child, the next + - before, the child is TT. In the (eq e cy v o pex, ) system, the fixed 4 is in the T (e v o pex g, ) system, and the upstream and downstream sub-configurations are 1 in different uplink and downlink sub-configurations.

In the T system, there are 7 different gods in the uplink and downlink configuration, and the configuration is determined by the high level of the system. With configuration 0, it can be used as the descending sub-zero 0, 1, 5, 6 4 meson, combined with 1, in the sub-user, the user's reverse AC / AC information can be reversed with the 7-Meson, that is, 7, on the uplink sub-8

In sub 6 , the inverse AC / AC information is the same as the 4 meson , ie 4 , on the upstream sub 1 .

If the user's opposite AC information is expressed, then according to the previous multi-day shot, the new user's counter-balanced AC information indicates that the user is still in accordance with the previous multi-day shooting method. AC information, and AC information, then the sheep must be.

Step, sheep can include the way Way b sheep way C way.

Among them, the way. Can subdivide force

The number of the number contains the number of the new number and the number of the mediation 2) Since the number required is reduced by half, the original RB can be halved, and the CS number is not

3) The number of original RBs of the sheep is not, CS is reduced, that is, and the coding mode is lowered.

However, the number of sheep in the above three ways, in the user's own, if the original bit is not, then the ARQ can be combined, and the ARQ can be increased. Otherwise, the original bit can not be combined with the ARQ, and the ARQ cannot be gained.

In the above method, the user needs to reverse the information of the downlink. The number of CS= 0, RB 24, last used

In 3, P ( ecod gax dcao ) indicates that the index CS of the precoding matrix on each user indicates the coding mode, and the above CS may be the same or different RV ( ed da cy o ) for the remaining version, the new RV ( Ew daa dcao, new instructions) 0 means new , =1 means. Usually TE sets the upper limit of 4, so RV is 0 to 3.

In the last 1 , 2 , the next step of the shooting method

Step 1 Compare R (Ra dcao ) 1 of the reversed matrix of the user. If R is greater than 1, then step 2, if R is equal to 1, then step 3.
