A method and apparatus for feeding back and receiving a CQI and a communications system. The method for feeding back a CQI includes: receiving by a user equipment indication information for NOMA CQI feedback transmitted by a base station, the indication information including at least an NOMA power allocation factor; calculating an NOMA signal-to-interference plus noise ratio based on the NOMA power allocation factor; obtaining a corresponding NOMA CQI based on the NOMA signal-to-interference plus noise ratio; and feeding back the NOMA CQI to the base station. Therefore, by feeding back the NOMA CQI by the user equipment, quantization error accumulation may be reduced and accuracy of MCS selection may be enhanced.
An apparatus for feeding back a channel quality indicator (CQI), configured in a user equipment of a non-orthogonal multiple access (NOMA) system, the apparatus comprising:
