Statistical projection for controlling BLER

1. A method of determining a block error rate (BLER) and determining if the BLER is above, below or on BLER target comprising;

determining a pair of thresholds including an upper threshold and a lower threshold for a predetermined confidence level;

determining a threshold in total number of blocks received; determining a Required Compensation BLER from a number of bad blocks, a total number of blocks received and a maximum total number of blocks to receive for a purpose of statistical significance;

comparing the Required Compensation BLER against the upper and lower threshold to determine if the BLER is above the BLER target, below the BLER target or inconclusive;

wherein, if the threshold in total number of blocks received is reached, then the inconclusive result is reinterpreted as the BLER being on target.

2. The method of claim 1 wherein the pair of thresholds are valid for any number of received blocks, a specific BLER target, and a specific confidence value.

3. The method of claim 1 wherein the BLER is determined from a number of bad blocks divided by a total number of blocks received.

4. The method of claim 1 wherein the Required Compensation BLER is calculated by determining a first value by subtracting a total number of blocks received so far from the maximum number of blocks to be received and dividing a total number of bad blocks allowed by the first value.

5. The method of claim 1 wherein the threshold for the total number of blocks received is calculated by determining a first value by subtracting the lower threshold from the BLER target, determining a second value by multiplying the BLER target by a BLER target range factor and subtracting the lower threshold from the result, and dividing the first value by the second value.

6. The method of claim 1 wherein when the BLER is significantly above the BLER target then increasing a Signal to Interference Ratio (SIR) target.

7. The method of claim 1 wherein when the BLER is significantly below the BLER target then decreasing a Signal to Interference Ratio (SIR) target.

8. The method of claim 1 further comprising resetting block statistics.

9. A method of determining a block error rate (BLER) and determining if BLER is above, below or on BLER target comprising:

determining a set of pairs of thresholds including an upper threshold and a lower threshold for a predetermined confidence level per pair;

determining a maximum total number of blocks received;

determining a BLER from a number of bad blocks and a total number of blocks received; comparing the BLER against a particular upper and lower threshold from the set of pairs of thresholds to determine if the BLER is above the BLER target, below the BLER target or inconclusive;

wherein, if the maximum total number of blocks received is reached, then the inconclusive result is reinterpreted as the BLER being on target.

10. The method of claim 9 wherein the pair of thresholds are valid for any number of received blocks, a specific BLER target and a specific confidence value.

11. The method of claim 9 wherein the BLER is determined from a number of bad blocks divided by a total number of blocks received.

12. The method of claim 9 wherein the threshold for the total number of blocks received is calculated by determining a first value by subtracting the lower threshold from the BLER target, determining a second value by multiplying the BLER target by a BLER target range factor and subtracting the lower threshold from the result, and dividing the first value by the second value.

13. The method of claim 9 wherein when the BLER is significantly above the BLER target then increasing a Signal to Interference Ratio (SIR) target.

14. The method of claim 9 wherein when the BLER is significantly below the BLER target then decreasing a Signal to Interference Ratio (SIR) target.

15. The method of claim 9 further comprising resetting block statistics.
