In the GSM system, the requirements for carrier-to-interference ratio are? (Multiple choice)

• A.  Adjacent frequency carrier-to-interference ratio: C/I ≥ -9dB, add 3dB margin in engineering, ie C/I ≥ -6dB
• B.  Same frequency carrier-to-interference ratio: C/I ≥ 9dB, add 3dB margin in engineering, ie C/I ≥ 12dB
• C.  Carrier-to-interference ratio when the carrier deviates from 400KHz: C/I (carrier/interference) ≥ -61dB
• D.  Carrier-to-interference ratio when the carrier deviates from 400KHz: C/I (carrier/interference) ≥ -41dB
