For example, according to certain aspects, devices may exchange information regarding the number of beamforming transmit sectors each device plans to use for both partial and full sector sweeps, as well as the number of receive antennas. The devices may also exchange timing information used to synchronize when the devices start to perform the partial and full sector sweeps, after detecting a lost link. onion °nolo momiooliolloomiliflo oimIE (10) International Publication Number WO 2018/160672 Al
