Beam reporting enhancement for simultaneous IAB reception

An apparatus comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to:
• perform beam measurement for downlink beams received with the apparatus from at least one second node;
• schedule at least one third node for uplink transmission to the apparatus;
• determine one or more of the downlink beams that can be received simultaneously with a beam of the at least one third node based, at least partially, on the scheduling of the at least one third node and the performing of the beam measurement;
• and
• transmit results of the performed beam measurement, wherein the results comprise an indication of the one or more determined downlink beams that can be received simultaneously with the beam of the at least one third node.

An apparatus comprising:

• at least one processor;
• and
• at least one storing instructions that, when executed with the at least one processor, cause the apparatus to:
• transmit, to a first node, an indication of one or more resources a second node is configured to use for downlink transmission;
• receive, from the first node, beam reporting for the one or more resources, wherein the beam reporting comprises an indication of at least one resource of the one or more resources that can be received with the first node simultaneously with a beam of a third node;
• activate one or more of the at least one indicated resource;
• and
• perform downlink transmission, to the first node, with the one or more activated resources.
