Example embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage medium for beamlock on a plurality of antenna arrays. In a method, a first apparatus receives a beamlock message from a second apparatus. The beamlock message indicates that one or more transmitting beams are to be locked on a first list of antenna arrays and/or one or more receiving beams are to be locked on a second list of antenna arrays. Based on the beamlock message, the first apparatus performs beamlock of the one or more transmitting beams and/or the one or more receiving beams.
