Certain aspects of the present disclosure provide techniques for beam pair selection. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), an indication to report one or more beam pairs to be used for full-duplex (FD) communication based on a timing constraint, wherein the timing constraint comprises a constraint on a time difference between receptions, at the UE, of a downlink (DL) signal and an uplink (UL) signal for each of the one or more beam pairs and transmitting a report specifying the one or more beam pairs in accordance with the indication, in accordance with aspects of the present disclosure.
