Claims
- 1. A communications method comprising:
measuring a signal strength of a carrier; and determining a signal quality estimate based on the measured signal strength.
- 2. The method of claim 1, wherein the signal strength is a received signal strength indicator (RSSI) of a downlink signal for a co-sited carrier.
- 3. The method of claim 1, wherein the signal quality estimate is an estimate of CPICH Ec/IO.
- 4. The method of claim 1, further comprising estimating a value of RSCP.
- 5. The method of claim 4, wherein the estimated value of the RSCP is based on a difference of frequencies and a difference of transmission powers.
- 6. The method of claim 4, wherein the signal quality estimate is based on the measured signal strength and the estimated value of RSCP.
- 7. The method of claim 1, further comprising avoiding uplink interference based on the determined signal quality estimate.
- 8. The method of claim 1, further comprising detecting interference based on the determined signal quality estimate.
- 9. The method of claim 1, further comprising performing a handover based on the determined signal quality estimate.
- 10. A method for uplink interference avoidance comprising:
determining a signal quality based on a signal strength of a co-sited carrier; and performing an operation based on the determined signal quality in order to avoid uplink interference.
- 11. The method of claim 10, further comprising measuring the signal strength of the co-sited carrier.
- 12. The method of claim 11, wherein the signal strength is a received signal strength indicator (RSSI) of a downlink signal for the co-sited carrier.
- 13. The method of claim 10, wherein the signal quality is an estimate of CPICH Ec/IO.
- 14. The method of claim 10, wherein determining the signal quality includes estimating a value of RSCP.
- 15. The method of claim 14, wherein the estimated value of RSCP is based on a difference of frequencies and a difference of transmission powers.
- 16. The method of claim 14, wherein the signal quality is based on the measured signal strength and the estimated value of RSCP.
- 17. The method of claim 10, wherein performing an operation comprises performing a handover based on the determined signal quality.
- 18. A communications system comprising:
at least one network device in a communications network; and a mobile device, the mobile device operatively connected to the communications network, wherein the mobile device measures a signal strength of a carrier, and the communication system includes a capability to determine a signal quality estimate based on the measured signal strength.
- 19. The system according to claim 18, wherein the network device comprises a radio network controller to determine the signal quality estimate.
- 20. The system of claim 18, wherein the signal strength is a received signal strength indicator (RSSI) of a downlink signal for a co-sited carrier.
- 21. The system of claim 18, wherein the signal quality estimate is an estimate of CPICH Ec/IO.
- 22. The system of claim 18, wherein the communications system further includes the capability to estimate a value of RSCP.
- 23. The system of claim 22, wherein the estimated value of RSCP is based on a difference of frequencies and a difference of transmission powers.
- 24. The system of claim 22, wherein the signal quality estimate is based on the measured signal strength and the estimated value of RSCP.
- 25. The system of claim 18, wherein the communications system avoids uplink interference based on the determined signal quality estimate.
- 26. The system of claim 18, wherein the communications system detects interference based on the determined signal quality estimate.
- 27. The system of claim 18, wherein the communications system performs a handover based on the determined signal quality estimate.
