Abstract

Systems, methods and computer programs are disclosed for providing an indication of a decoding problem in a wireless system. A problem is detected in decoding uplink physical control channels for a Dedicated Physical Control Channel (DPCCH) or an Enhanced Dedicated Physical Control Channel (E-DPCCH). A modified Up Link (UL) Dedicated Channel (DCH) frame having a spare field modified to indicate a Transport Format Combination Indicator (TFCI) decode failure is sent. In response to receiving the modified UL DCH frame, an Up Link (UL) Outer-Loop Power Control (OLPC) is controlled to keep a signal-to-interference ratio (SIR) of the UL DPCCH within a predetermined range.

Claims

1. A method for providing an indication of a decoding problem, comprising:

detecting a problem in decoding uplink physical control channels for a Dedicated Physical Control Channel (DPCCH) or an Enhanced Dedicated Physical Control Channel (E-DPCCH);

sending a modified Up Link (UL) Dedicated Channel (DCH) frame having a spare field modified to indicate a Transport Format Combination Indicator (TFCI) decode failure; and

in response to receiving the modified UL DCH frame, controlling an Up Link (UL) Outer-Loop Power Control (OLPC) to keep a signal-to-interference ratio (SIR) of the UL DPCCH within a predetermined range.

2. The method of claim 1, wherein the sending the modified UL DCH frame is used for 2G, 3G, 4G, Long-Term Evolution (LTE) or 5G Radio Access Technologies (RATs).

3. The method of claim 1, further comprising using, by the OLPC, the modified UL DCH frame to readjust gain factors.

4. The method of claim 1, further comprising using, by the OLPC, the modified UL DCH frame to readjust power offsets.

5. The method of claim 1, further comprising using, by the OLPC, the modified UL DCH frame to optimize power consumption of uplink control and data channels to maximize cell capacity.

6. The method of claim 1, further comprising using, by the OLPC, the modified UL DCH frame offline to readjust gain factors.

7. The method of claim 1, further comprising using, by the OLPC, the modified UL DCH frame offline to readjust power offsets.

8. The method of claim 1, further comprising using, by the OLPC, the modified UL DCH frame offline to optimize power consumption of uplink control and data channels to maximize cell capacity.

9. The method of claim 1, further comprising using, by the OLPC, the modified UL DCH frame to set a low-bound limit in an SIR target to ensure the DPCCH and the E-DPCCH SIR do not fall below the low-bound limit.

10. A non-transitory computer-readable medium containing instructions which, when executed, cause a wireless communications system to perform steps comprising:

detecting a problem in decoding uplink physical control channels for a Dedicated Physical Control Channel (DPCCH) or an Enhanced Dedicated Physical Control Channel (E-DPCCH);

17. The non-transitory computer-readable medium of claim 10, further comprising instructions wherein the OLPC uses the modified UL DCH frame offline to optimize power consumption of uplink control and data channels to maximize cell capacity.

18. The non-transitory computer-readable medium of claim 10, further comprising instructions wherein the OLPC uses the modified UL DCH frame to set a low-bound limit in an SIR target to ensure the DPCCH and the E-DPCCH SIR does not fall below the low-bound limit.

19. A system for providing an indication of a decoding problem, comprising:

a User Equipment (UE);

a base station in wireless communication with the UE;

wherein a problem is detected by the UE in decoding uplink physical control channels for a Dedicated Physical Control Channel (DPCCH) or an Enhanced Dedicated Physical Control Channel (E-DPCCH);
