Method and apparatus for reporting channel state information

An apparatus for configuring channel state information reporting, the apparatus comprising:

• a first transmitter, configured to transmit a channel state information (CSI) report configuration, the CSI report configuration being related to L CSI sub-reports, the CSI report configuration comprising a first sub-configuration list, the first sub-configuration list comprising L sub-configurations, one of the L sub-configurations corresponds to one of the L CSI sub-reports;
• a second transmitter, configured to transmit indication information, the indication information being used to trigger/indicate/activate M sub-configurations of the L sub-configurations, M equals to or more than 1 and less than or equal to L;
• wherein the CSI report configuration is for semi-persistent reporting on PUSCH;
• and a first trigger state list is configured via a higher layer signaling, the first trigger state list comprising a set of trigger states;
• or, the CSI report configuration is for aperiodic reporting on PUSCH;
• and a second trigger state list is configured via a higher layer signaling, the second trigger state list comprising a set of trigger states.

A communication system, comprising:

• a network device, configured to transmit a channel state information (CSI) report configuration and indication information;
• and
• a terminal equipment, configured to receive the CSI report configuration and the indication information;
• wherein the CSI report configuration is related to L CSI sub-reports, the CSI report configuration comprising a first sub-configuration list, the first sub-configuration list comprising L sub-configurations, one of the L sub-configurations corresponds to one of the L CSI sub-reports;
• the indication information is used to trigger/indicate/activate M sub-configurations of the L sub-configurations, M equals to or more than 1 and less than or equal to L;
• wherein the CSI report configuration is for semi-persistent reporting on PUSCH;
• and a first trigger state list is configured via a higher layer signaling, the first trigger state list comprising a set of trigger states;
• or, the CSI report configuration is for aperiodic reporting on PUSCH;
• and a second trigger state list is configured via a higher layer signaling, the second trigger state list comprising a set of trigger states.
