A system and/or method for determining an Angle of Arrival (AoA) of a signal by a base station. The technique may include configuring different time intervals and multiple phase shifts across an antenna array of the base station. The technique may include receiving the signal from UEs at the different time intervals and the multiple phase shifts across the antenna array. The technique may include estimating phase angles of the signal received at the different time intervals and the multiple phase shifts. The technique may include determining the AoA of the signal received from the UEs based on the phase angles of the signal received at the different time intervals and the multiple phase shifts.
