Modulation processing method and device

A base station, comprising:

• a configuration information transmitting unit, configured to:
• transmit a high-layer configuration signaling to a user equipment (UE), wherein the high-layer configuration signaling is used to indicate whether to support a high-order Quadrature Amplitude Modulation (QAM) modulation scheme, and the high-order QAM modulation scheme is a modulation scheme of M QAM, wherein M is a number greater than 64;
• wherein, the base station further comprises:
• a channel state information receiving unit, configured to receive channel state information of the UE, wherein the channel state information at least comprises channel quality indication (CQI) information, when the high-layer configuration signaling indicates not supporting the high-order QAM modulation scheme, the CQI information is obtained based on the first CQI table which does not support the high-order QAM modulation scheme, when the high-layer configuration signaling indicates supporting the high-order QAM modulation scheme, the CQI information is obtained based on the second CQI table which supports the high-order QAM modulation scheme.

A user equipment (UE), wherein, the UE comprises:

• a configuration information receiving unit, configured to receive a high-layer configuration signaling transmitted by a base station, wherein the high-layer configuration signaling is used to indicate whether to support a high-order Quadrature Amplitude Modulation (QAM) modulation scheme, and the high-order QAM modulation scheme is a modulation scheme of M QAM, wherein M is a number greater than 64;
• wherein, the UE further comprises:
• a channel state information reporting unit, configured to:
• transmit channel state information to the base station, wherein the channel state information comprises at least channel quality indication (CQI) information, and when the high-layer configuration signaling indicates not supporting the high-order QAM modulation scheme, the CQI information is obtained based on a first CQI table which does not support the high-order QAM modulation scheme, and when the high-layer configuration signaling indicates supporting the high-order QAM modulation scheme, the CQI information is obtained based on a second CQI table which supports the high-order QAM modulation scheme.
