1. One or more non-transitory computer-readable media having instructions that, when executed by one or more processors, cause a device to:
perform a plurality of beam measurements corresponding to a beam received by the device;
determine a plurality of local angle of arrival (AoA) estimates corresponding to the beam based at least in part on the plurality of beam measurements;
convert the plurality of local AoA estimates to a plurality of global AoA estimates;
convert a first set of local AoA estimates of the plurality of local AoA estimates to a first set of global AoA estimates of the plurality of global AoA estimates, the first set of local AoA estimates to correspond to a first time;
convert a second set of local AoA estimates of the plurality of local AoA estimates to a second set of global AoA estimates of the plurality of global AoA estimates, the second set of local AoA estimates to correspond to a second time;
determine a global AoA that corresponds to a first global AoA estimate of the first set of global AoA estimates and a second global AoA estimate of the second set of global AoA estimates based at least in part on a determination that the first global AoA estimate overlaps with the second global AoA estimate; and
utilize the global AoA to identify a beam received from a base station.
