Techniques for selecting beams in full duplex wireless communications

An apparatus for wireless communication, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• transmit, to a user equipment (UE), a first indication of a set of candidate downlink beams corresponding to multiple downlink beams transmitted from one or more transmit/receive points (TRPs);
• transmit, to the UE, a second indication of a set of candidate uplink beams of multiple uplink beams, wherein at least one downlink beam in the set of candidate downlink beams includes a downlink beam combination of multiple downlink beams or at least one uplink beam in the set of candidate uplink beams includes an uplink beam combination of multiple uplink beams;
• transmit, to the UE, each candidate downlink beam in the set of candidate downlink beams;
• and
• receive, from the UE, a third indication of a set of candidate beam pairs based on receiving each candidate downlink beam in the set of candidate downlink beams while transmitting each candidate uplink beam in the set of candidate uplink beams.

A method for wireless communication, comprising:

• receiving, from a network node, a first indication of a set of candidate downlink beams corresponding to multiple downlink beams received from one or more transmit/receive points (TRPs);
• receiving, from the network node, a second indication of a set of candidate uplink beams of multiple uplink beams, wherein at least one downlink beam in the set of candidate downlink beams includes a downlink beam combination of multiple downlink beams or at least one uplink beam in the set of candidate uplink beams includes an uplink beam combination of multiple uplink beams;
• performing beam pair measurements of each candidate downlink beam in the set of candidate downlink beams received while transmitting each candidate uplink beam in the set of candidate uplink beams to select a set of candidate beam pairs each including one of the candidate downlink beams and one of the candidate uplink beams;
• and
• reporting, to the network node, a third indication of the set of candidate beam pairs.

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

• transmitting, to a user equipment (UE), a first indication of a set of candidate downlink beams corresponding to multiple downlink beams transmitted from one or more transmit/receive points (TRPs);
• transmitting, to the UE, a second indication of a set of candidate uplink beams of multiple uplink beams, wherein at least one downlink beam in the set of candidate downlink beams includes a downlink beam combination of multiple downlink beams or at least one uplink beam in the set of candidate uplink beams includes an uplink beam combination of multiple uplink beams;
• transmitting, to the UE, each candidate downlink beam in the set of candidate downlink beams;
• and
• receiving, from the UE, a third indication of a set of candidate beam pairs based on receiving each candidate downlink beam in the set of candidate downlink beams while transmitting each candidate uplink beam in the set of candidate uplink beams.
