Beam training resource selection by FR2 sidelink UE

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

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determine to perform beam training with a second UE in a set of beam training resources that is semi-statically configured as part of a beam training occasion, the set of beam training resources including a first subset of beam training resources for UEs without a radio resource control (RRC) connection with a UE associated with the beam training and a second subset of beam training resources for UEs with an RRC connection with the UE associated with the beam training, the first subset of beam training resources and the second subset of beam training resources being non-overlapping;
• determine whether the first UE is RRC connected with the second UE;
• and
• perform beam training in the first subset of beam training resources based on a determination that the first UE is not RRC connected with the second UE or in the second subset of beam training resources based on a determination that the first UE is RRC connected with the second UE.

A non-transitory computer-readable medium storing computer executable code, the computer executable code when executed by at least one processor of a first user equipment (UE) causes the at least one processor to:

• determine to perform beam training with a second UE in a set of beam training resources that is semi-statically configured as part of a beam training occasion, the set of beam training resources including a first subset of beam training resources for UEs without a radio resource control (RRC) connection with a UE associated with the beam training and a second subset of beam training resources for UEs with an RRC connection with the UE associated with the beam training, the first subset of beam training resources and the second subset of beam training resources being non-overlapping;
• determine whether the first UE is RRC connected with the second UE;
• and
• perform beam training in the first subset of beam training resources based on a determination that the first UE is not RRC connected with the second UE or in the second subset of beam training resources based on a determination that the first UE is RRC connected with the second UE.
