… beam alignment without scanning the space. Given all possible directions for setting the
antenna beam… Our results show that it reduces beam alignment delay by orders of magnitude. In …

… In this paper, we proposed an efficient Beam Alignment (BA) scheme for mm-Wave
multiuser MIMO systems. In the proposed scheme, the AoA/AoD of a strong MPC component is …

… In order to align BS/UE beams, a hierarchical training approach that employs multi-resolution
beam codebooks is considered. In the beam alignment process, we assume that the BS …

… beamalignment scheme followed by data communication is optimal, and we prove the
optimality of a decoupled fractional search method, which decouples over time the alignment of …

Recently, millimeter-wave (mmWave) bands have been postulated as a means to accommodate
the foreseen extreme bandwidth demands in vehicular communications, which result …

… the problem of beam alignment in millimeter wave (mmWave… the transmitter and receiver
beams need to be aligned, which … , requiring more frequent beam alignment and signal training. …

… Abstract—Owing to abundant spectrum resources, millimeter wave (mmwave) … with beam
alignment (BA) as an important step to achieve the array gain. Efficient BA relies on the beam …

… to-many millimeter wave beam alignment protocol that efficiently aligns the beams of many
APs … must address two key questions: (1) How does BounceNet align the beams of all the APs …

… To align the beam direction of a large number of antennas, we develop a beam alignment
… Then, we propose a soft-decision beam alignment (soft-alignment) algorithm that exploits …

… Therefore, fast UAV beam alignment is required to reduce the significant overhead brought
by beam training and link mobility. In this paper, we consider the problem of beam alignment …
