Configuring a channel state information report

A method performed by a user equipment (UE), the method comprising:

• receiving a channel state information (CSI) reporting setting;
• receiving a CSI resource setting that corresponds to at least one CSI reference signal (CSI-RS) resource;
• identifying at least one combination of configurations;
• generating a set of CSI feedback parameters based on the at least one combination of configurations;
• and
• transmitting a set of at least one CSI report of a plurality of CSI reports to a network, wherein each CSI report of the at least one CSI report:
• comprises a channel quality indicator (CQI) indicating a configuration mode of a plurality of configuration modes, wherein the plurality of configuration modes comprises a first configuration mode and a second configuration mode, and wherein values of a subset of the set of CSI feedback parameters corresponding to the second configuration mode are computed in a differential manner with respect to values of an equivalent subset of the set of CSI feedback parameters corresponding to the first configuration mode;
• corresponds to at least one type of a codebook configured via a codebook configuration;
• comprises the set of CSI feedback parameters;
• and
• comprises at least one CSI part.

A base station, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the base station to:
• transmit a channel state information (CSI) reporting setting;
• transmit a CSI resource setting that corresponds to at least one CSI reference signal (CSI-RS) resource;
• receive a set of at least one CSI report of a plurality of CSI reports, wherein each CSI report of the at least one CSI report:
• comprises a channel quality indicator (CQI) indicating a configuration mode of a plurality of configuration modes, wherein the plurality of configuration modes comprises a first configuration mode and a second configuration mode, and wherein values of a subset of a set of CSI feedback parameters corresponding to the second configuration mode are computed in a differential manner with respect to values of an equivalent subset of the set of CSI feedback parameters corresponding to the first configuration mode;
• corresponds to at least one type of a codebook configured via a codebook configuration;
• comprises the set of CSI feedback parameters;
• and
• comprises at least one CSI part.
