Configurations for omitting channel state information

A base station for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory, wherein the at least one processor is configured to:
• configure one or more channel state information reporting parameters for a channel state information report, the one or more channel state information reporting parameters comprising a number of frequency domain bases, a number of spatial domain bases, a number of non-zero coefficients (NNZCs), or any combination thereof;
• transmit, to a user equipment (UE), an indication to use one of one or more channel state information omission configurations for omitting a portion of the channel state information report, wherein a first channel state information omission configuration of the one or more channel state information omission configurations corresponds to the channel state information report including at least a first portion of the NNZCs and excluding at least a second portion of the NNZCs, wherein the first portion of the NNZCs and the second portion of the NNZCs are each based at least in part on a spatial domain basis, a frequency domain basis, one or more layers, a strength metric, or any combination thereof;
• transmit, to the UE, a trigger for the channel state information report that is based at least in part on the configured one or more channel state information reporting parameters;
• and
• receive, from the UE, the channel state information report that omits a portion of the channel state information report in accordance with the one of the one or more channel state information omission configurations based at least in part on the indication.

A method for wireless communication performed by a user equipment (UE), comprising:

• receiving, from a base station, a trigger for a channel state information report;
• identifying a payload for the channel state information report and uplink resources for transmitting the channel state information report based at least in part on the trigger;
• identifying one or more channel state information reporting parameters associated with generating the channel state information report, the one or more channel state information reporting parameters comprising a number of frequency domain bases, a number of spatial domain bases, a number of non-zero coefficients (NNZCs), or any combination thereof;
• determining to use one or more channel state information omission configurations to omit a portion of the channel state information report, wherein the determination is based at least in part on the one or more channel state information reporting parameters, the payload, and the uplink resources, wherein a first channel state information omission configuration of the one or more channel state information omission configurations corresponds to the channel state information report including at least a first portion of the NNZCs and dropping at least a second portion of the NNZCs, wherein the first portion of the NNZCs and the second portion of the NNZCs are each based at least in part on a spatial domain basis, a frequency domain basis, one or more layers, a strength metric, or any combination thereof;
• and
• transmitting, to the base station, the channel state information report that excludes the omitted portion based at least in part on the determination.

• and
• receiving, from the UE, the channel state information report that omits a portion of the channel state information report in accordance with the one of the one or more channel state information omission configurations based at least in part on the indication.
