Interference pattern measurement and signaling

An apparatus for wireless communications at a network entity, comprising:

• one or more processors;
• and
• instructions stored in one or more memories and executable by the one or more processors, individually or collectively, to cause the apparatus to:
• obtain a reporting message comprising information indicative of one or more interference patterns, the one or more interference patterns associated with one or more signals that interfere with a message transmitted via a physical downlink channel;
• and
• output a control message indicating a configuration for a plurality of reference signals associated with estimation of an interference covariance matrix, wherein the configuration is based at least in part on the one or more interference patterns.

A method for wireless communications at a user equipment (UE), comprising:

• detecting one or more signals that interfere with a message received via a physical downlink channel;
• performing, for a plurality of symbol periods associated with the physical downlink channel, one or more interference covariance matrix estimation computations based at least in part on the one or more signals, wherein one or more interference patterns across the plurality of symbol periods are based at least in part on the one or more interference covariance matrix estimation computations for the one or more signals;
• and
• transmitting, to a network entity, a reporting message comprising information indicative of the one or more interference patterns.
