The use of high-frequency bands like millimeter-wave and terahertz causes higher path loss and shadowing, which leads to the requirement of narrow beams. Beam Alignment (BA) is a method to efficiently adjust the direction of these beams by exploiting the channel sparsity at high frequencies. This research focuses on the uplink scenario where there are multiple paths between the user equipment and the base station. The goal is for the base station to find the best beams with a given resolution with the least number of time slots by using a hybrid beamforming technique to scan the angular region. To achieve this, a group testing framework is developed with associated analog and hybrid BA strategies. Simulation studies show that these strategies improve performance in both noiseless and realistic 5G mmWave BA settings.
