1. A method of wireless communication for a first user equipment (UE), comprising:
determining (1) a first set of candidate beam pair links (BPLs) associated with a first sidelink (SL), the first UE transmitting data to a second UE via the first SL and (2) a second set of candidate BPLs associated with a second SL, the first UE receiving data from the second UE via the second SL;
determining a configuration for full-duplex (FD) beam training based on the determined first set of candidate BPLs and the determined second set of candidate BPLs, the configuration for FD beam training comprising a plurality of instances for which the first UE transmits and receives reference signals (RS) at a same time;
selecting, based on the determined configuration for FD beam training, (1) a first BPL in the first set of candidate BPLs for the first SL and (2) a second BPL in the second set of candidate BPLs for the second SL; and
establishing FD communication with the second UE based on the selected first BPL and the selected second BPL.
