Interference layer categorization and non zero power interference measurement resource for non linear precoding

A method for wireless communication at a network device, comprising:

• receiving, from a user equipment (UE), a support indicator that indicates a threshold quantity of non-linear precoding layers supported by the UE;
• transmitting a configuration of a first one or more reference signal ports associated with at least one data stream for the UE, the first one or more reference signal ports being different from a second one or more reference signal ports unassociated with the at least one data stream for the UE, wherein the configuration is based at least in part on the support indicator;
• transmitting an indicator indicating a categorization of each of the second one or more reference signal ports as corresponding to one of a first type of precoding layer or a second type of precoding layer, wherein a first subset of the second one or more reference signal ports are categorized as a non-linear precoding layer and a second subset of the second one or more reference signal ports are categorized as a linear precoding layer and wherein a quantity of the first subset of the second one or more reference signal ports is less than or equal to the threshold quantity of non-linear precoding layers supported by the UE;
• and
• transmitting the at least one data stream using the first one or more reference signal ports.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit, from the UE, a support indicator that indicates a threshold quantity of non-linear precoding layers supported by the UE;
• receive a configuration of a first one or more reference signal ports associated with at least one data stream for the UE, the configuration being based at least in part on the support indicator;
• identify a second one or more reference signal ports unassociated with the at least one data stream for the UE;
• receive an indicator indicating a categorization of each of the second one or more reference signal ports as corresponding to one of a first type of precoding layer or a second type of precoding layer, wherein a first subset of the second one or more reference signal ports are categorized as a non-linear precoding layer and a second subset of the second one or more reference signal ports are categorized as a linear precoding layer, and wherein a quantity of the first subset of the second one or more reference signal ports is less than or equal to the threshold quantity of non-linear precoding layers supported by the UE;
• receive a transmission associated with the first one or more reference signal ports;
• and
• decode the transmission to obtain the at least one data stream based at least in part on the categorization of the second one or more reference signal ports.
