Techniques for rank-aware interference rejection based on neighbor cell layer notification

A first network entity, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the first network entity to:
• receive, from a user equipment (UE) served by the first network entity, a first message comprising a request for a quantity of transmission layers scheduled to be used by one or more neighbor network entities for communication within a communication resource;
• transmit, to a second network entity, a second message comprising a request for the quantity of transmission layers for the communication resource;
• receive, from the second network entity, a third message comprising an indication of the quantity of transmission layers for the communication resource;
• and
• transmit, to the UE, the indication of the quantity of transmission layers for the communication resource.

A second network entity, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the second network entity to:
• receive, from a first network entity, a message comprising a request a quantity of transmission layers scheduled to be used by one or more neighbor network entities for communication within a communication resource;
• request, from at least one neighbor network entity of the one or more neighbor network entities, a quantity of transmission layers scheduled to be used by the at least one neighbor network entity for communication within the communication resource;
• and
• transmit, to the first network entity, an indication of the quantity of transmission layers scheduled to be used by the at least one neighbor network entity for communication within the communication resource.
