Optimal Single-User Interactive Beam Alignment with Feedback Delay

  title={Optimal Single-User Interactive Beam Alignment with Feedback Delay},
  author={Abbas Khalili and Shahram Shahsavari and Mohammad Ali Amir Khojastepour and Elza Erkip},
Communication in Millimeter wave (mmWave) band relies on narrow beams due to directionality, high path loss, and shadowing. One can use beam alignment (BA) techniques to find and adjust the direction of these narrow beams. In this paper, BA at the base station (BS) is considered, where the BS sends a set of BA packets to scan different angular regions while the user listens to the channel and sends feedback to the BS for each received packet. It is assumed that the packets and feedback received… 



On Single-User Interactive Beam Alignment in Millimeter Wave Systems: Impact of Feedback Delay

This paper investigates BA strategies that operate under arbitrary fixed feedback delays and reveals potential performance improvements in terms of the BA duration it takes to achieve a fixed expected width of the UR over the stateof-the-art BA methods which do not consider the effect of delay.

On Optimal Multi-user Beam Alignment in Millimeter Wave Wireless Systems

A class of multi-user BA schemes where the base station performs a one shot scan of the angular domain to simultaneously localize multiple users to minimize the average of expected width of remaining uncertainty regions (UR) on the AoDs after receiving users' feedbacks is considered.

Efficient Beam Alignment for Millimeter Wave Single-Carrier Systems With Hybrid MIMO Transceivers

The proposed BA scheme is highly robust to fast channel variations caused by the large Doppler spread between the multipath components, and it is shown that after achieving BA, the beamformed channel is essentially frequency-flat, such that single-carrier communication needs no equalization in the time domain.

Optimal Beam-Sweeping and Communication in Mobile Millimeter-Wave Networks
